Comparison Nokia 800 Tough 4 GB / 0.5 GB vs Nokia 8110 4G 4 GB / 0.5 GB

The largest volume of memory card with which the phone supports. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious cards often use advanced technologies that are not supported by all devices, and sometimes phones simply do not have enough power to process large amounts of data. Therefore, for the convenience of choosing in our catalog, the maximum supported volume is indicated.

In fact, there are cases when some devices may exceed the claimed characteristics. However, it is worth focusing on official data, because, if officially supported volume is exceeded, normal operation of the card is not guaranteed.

The presence of a flash on the main camera of the phone.

Flash is a lamp for illuminating the photographed scene, it significantly expands the possibilities of shooting. In particular, it allows you to shoot in low light and against bright light. In addition, the flash can usually also be used as a flashlight(see "Options"), which eliminates the need to install two light sources in the phone.

The type of SIM card used in the mobile phone. The term SIM here means all types of cards for identification in mobile networks, including 3G networks, CDMA, etc. (although formally such cards may have other names). The type of such a card is primarily described by its form factor. Here are the most common options:

— micro SIM. The largest type of sim cards widely used in modern devices: its' size is 15x12 mm. It was introduced back in 2010, nowadays it is being replaced by more compact and advanced nano-SIM and eSIM. Keep in mind that a microSIM card can be made by simply cutting a larger mini-SIM to the dimensions mentioned above. However this is associated with a certain risk and requires accuracy, so it is better to contact your mobile carrier to replace the SIM card with a suitable one.

— Nano-SIM. The smallest form factor of classic (replaceable) SIM-cards is 12x9 mm. In such cards the frames are cut off almost to the very chip. This standard appeared back in 2012, but it is still extremely common. Like microSIM, a card for a slot of this format can be made by cutting a larger SIM card, but this requires extreme accuracy and is not recommended.

— e-SIM. This type of SIM card is an electronic module that is built directly into the device and cannot be replaced. To authorize in the network of a mobile carrier, you need to make the appropriate settings in the eSIM. Those m...odules are able to save several sets of settings at once, which makes it easy to switch between different carriers — no need to bother with the physical replacement of the SIM card, just change the profile in the settings. Another advantage of such modules is compactness. However, before buying a phone with an eSIM, you should clarify whether this technology is supported by your mobile carrier — even nowadays, not every network is compatible with such modules.

— nano+eSIM. An option found in smartphones with two SIM cards. The built-in eSIM module in such a device is complemented by a slot for a replaceable nanoSIM card. The features of each of these card types are detailed above. It is convenient to keep the main phone number (s) on eSIM, and use replacement cards for temporary numbers. Such scenario may come in handy if you travel abroad a lot — you can install cards from local carriers in the traditional nanoSIM slot.

The quantity and types of removable cards (SIM, memory cards) that can be installed in the phone. On E-Catalog this parameter is specified only for devices that allow the installation of more than one SIM card — most often that means 2 SIM cards, however, you can find devices with three or even four corresponding slots.

Initially several slots mean that several phone numbers can be used on one device. Thus it is possible to combine personal and work numbers, separate plans for calls and the Internet, etc. in one device. However modern devices (especially smartphones) often provide the combined design “SIM + SIM / memory card " : one of the slots is intended only for SIM, the second can be used both for a SIM card or for a memory card such as microSD or Nano Memory (see "Memory card slot"). At the same time, there is no separate slot for a memory card in the device, so the user has to choose between the second number and additional storage. Therefore, if you want to use 2 SIM cards and a memory card at the same time, you should pay attention to models where this is directly stated.

It is also worth considering that individual slots may differ in the type of compatible SIM cards; see below for details.

Types of communications supported by the device in addition to mobile networks.

This list includes two types of characteristics. The first is the communication technology itself: Wi-Fi (including advanced standards Wi-Fi 5 (802.11ac) , Wi-Fi 6 (802.11ax), Wi-Fi 6E (802.11ax) , Wi-Fi 7 (802.11be)), Bluetooth (including the new generation Bluetooth v 5 in the form of a version 5.0, 5.1, 5.2, 5.3 and 5.4), NFC, satellite communication. The second type is additional functions implemented through one or another communication standard: this is primarily aptX support (including aptX HD, aptX Adaptive and aptX Lossless) and even a built-in walkie-talkie. Here is a more detailed description of each of these characteristics:

— Wi-Fi 4 (802.11n). Wi-Fi is a wireless communication technology that in modern phones can be used both to access the Internet through wireless access points, and for direct...communication with other devices (in particular, cameras and drones). Wi-Fi is a must for smartphones, but is extremely rare in traditional phones. Specifically, Wi-Fi 4 (802.11n) provides data transfer speeds of up to 600 Mbit/s and uses two frequency ranges at once - 2.4 GHz and 5 GHz, making it compatible with earlier 802.11 b/g standards and with more new Wi-Fi 5 (see below). Wi-Fi 4 is considered a relatively modest standard by modern standards, but it is still quite sufficient for most tasks.

- Wi-Fi 5 (802.11ac). The Wi-Fi standard (see above), which is the successor to Wi-Fi 4. In theory, it supports speeds of up to 6.77 Gbps, and also uses the 5 GHz band - it is less loaded with extraneous signals and more noise-resistant than the traditional 2.4 GHz. For compatibility purposes, a smartphone with a Wi-Fi 5 module may provide support for earlier standards, but it would not hurt to clarify this point separately.

- WiGig (802.11ad). Further, after Wi-Fi 5, the development of Wi-Fi standards, characterized primarily by the use of the 60 GHz band. In terms of maximum speed, it is virtually no different from Wi-Fi 5, however, the higher frequency increases the channel capacity, so that when several gadgets simultaneously communicate with one common device (for example, a router), the communication speed does not drop as much as in earlier standards. On the other hand, the 802.11ad signal is almost incapable of passing through walls; Manufacturers use various tricks to compensate for this shortcoming, but the best communication quality is still achieved only with direct visibility. Relatively little equipment for the WiGig standard is currently being produced, and it is not compatible with earlier versions of Wi-Fi; Therefore, smartphones usually provide support for other standards.

- Wi-Fi 6 (802.11ax). A standard developed as a direct development and improvement of Wi-Fi 5. Uses the ranges from 1 to 7 GHz - that is, it is capable of operating at standard frequencies of 2.4 GHz and 5 GHz (including equipment of earlier standards), and in others frequency bands. The maximum data transfer rate has increased to 10 Gbps, but the main advantage of Wi-Fi 6 was not even this, but the further optimization of the simultaneous operation of several devices on the same channel (improving the technical solutions used in Wi-Fi 5 and WiGig). Thanks to this, Wi-Fi 6 gives the lowest speed drop among modern standards when the channel is busy.

- Wi-Fi 6E (802.11ax). The Wi-Fi 6E standard is technically called 802.11ax. But unlike basic Wi-Fi 6 (for more details, see the corresponding paragraph), which is named similarly, it provides for operation in the unused 6 GHz band. In total, the standard uses 14 different frequency bands, offering high throughput in the most crowded places with many active connections. And it is backwards compatible with previous versions.

— Wi-Fi 7 (802.11be). The technology, like the previous Wi-Fi 6E, is capable of operating in three frequency ranges: 2.4 GHz, 5 GHz and 6 GHz. At the same time, the maximum bandwidth in Wi-Fi 7 was increased from 160 MHz to 320 MHz - the wider the channel, the more data it can transmit. The IEEE 802.11be standard uses 4096-QAM modulation, which also allows more symbols to be accommodated in a data transmission unit. From Wi-Fi 7 you can squeeze out a maximum theoretical information exchange speed of up to 46 Gbps. In the context of using wireless connections for streaming and video games, the implemented MLO (Multi-Link Operation) development seems very interesting. With its help, you can aggregate several channels in different ranges, which significantly reduces delays in data transmission and ensures low and stable ping. And Multi-RU (Multiple Resource Unit) technology is designed to minimize communication delays when there are many connected client devices.

— Bluetooth. Direct wireless communication technology between various devices. In mobile phones it is used primarily for connecting headphones, headsets and wrist gadgets such as fitness bracelets, but other methods of application are also possible - remote control mode, direct file transfer, etc. In modern mobile phones there can be different versions of Bluetooth, here are their features:

• Bluetooth v 4.0. A fundamental update (after version 3.0), introducing another data transmission format - Bluetooth Low Energy (LE). This protocol is designed primarily for miniature devices that transmit small amounts of information, such as fitness bracelets and medical sensors. Bluetooth LE allows you to significantly save energy during such communication.
• Bluetooth v4.1. Development and improvement of Bluetooth 4.0. One of the key improvements was the optimization of collaboration with 4G LTE communication modules - so that Bluetooth and LTE do not interfere with each other. In addition, this version makes it possible to simultaneously use a Bluetooth device in several roles - for example, to remotely control an external device while simultaneously streaming music to headphones.
• Bluetooth v4.2. Further, after 4.1, the development of the Bluetooth standard. It did not provide any fundamental updates, but received a number of improvements regarding reliability and noise immunity, as well as improved compatibility with the Internet of Things.
• Bluetooth v 5.0. Version introduced in 2016. The key innovations were the further expansion of capabilities associated with the Internet of Things. In particular, in the Bluetooth Low Energy protocol (see above), it became possible to double the data transfer rate (up to 2 Mbit/s) at the cost of reducing the range, and also quadruple the range at the cost of reducing the speed; In addition, a number of improvements have been introduced regarding simultaneous work with a large number of connected devices.
• Bluetooth v5.1. Update of the version described above v 5.0. In addition to general improvements in the quality and reliability of communication, this update introduced such an interesting feature as determining the direction from which the Bluetooth signal is coming. Thanks to this, it becomes possible to determine the location of connected devices with centimeter accuracy, which can be useful, for example, when searching for wireless headphones.
• Bluetooth v 5.2. The next update after 5.1 is Bluetooth 5 generation. The main innovations in this version are a number of security improvements, additional optimization of power consumption in LE mode and a new audio signal format for synchronizing parallel playback on multiple devices.
• Bluetooth v 5.3. The Bluetooth v 5.3 wireless protocol was introduced at the dawn of 2022. Among the innovations in it, they accelerated the process of negotiating a communication channel between the controller and the device, implemented the function of quickly switching between the operating state in a low duty cycle and a high-speed mode, and improved the throughput and stability of the communication by reducing susceptibility to interference. When unexpected interference occurs in Low Energy mode, the procedure for selecting a communication channel to switch from now on has been accelerated. There are no fundamental innovations in protocol 5.3, but a number of qualitative improvements are evident in it.
• Bluetooth v5.4. Protocol version 5.4, which was introduced at the beginning of 2023, increased the range and speed of data exchange, which is well suited for use in applications that require communication over long distances (for example, smart home systems). Also in Bluetooth v 5.4, the energy-saving BLE mode has been improved. This version of the protocol uses new security features to protect data from unauthorized access, has increased communication reliability by selecting the best channel for communication, and prevents communication losses due to interference.

- aptX support. aptX technology was developed to improve the quality of sound transmitted over Bluetooth. When transmitting sound in a regular format, without aptX, the signal is compressed quite heavily, which affects the sound quality; This is not critical when talking on the phone, but it can significantly spoil the impression of listening to music. In turn, aptX allows you to transmit an audio signal with virtually no compression and achieve sound quality comparable to a wired communication. Such features will be especially appreciated by music lovers who prefer Bluetooth headphones or wireless speakers. Of course, to use aptX, both your smartphone and external audio device must support it.

- aptX HD support. aptX HD is a further development and improvement of the original aptX technology, allowing you to transmit sound in even higher quality - Hi-Res (24-bits/48kHz). According to the creators, this standard allows you to achieve signal quality superior to AudioCD and sound purity comparable to wired communication. The latter is often questionable, but it can be argued that overall aptX HD provides very high sound quality. On the other hand, all the advantages of this technology become noticeable only on Hi-Res audio - with quality 24-bits/48kHz or higher; otherwise, the quality is limited not so much by the characteristics of the communication as by the properties of the source files.

- Support for aptX LL. A modification of aptX technology, designed to minimize signal transmission delays. Encoding and decoding a signal when transmitting audio via Blueooth with aptX inevitably takes some time; This is not critical when listening to music, but in videos or games there may be a noticeable desynchronization between the image and sound. The aptX LL technology does not have this shortcoming; it also gives a delay, but this delay is so small that a person does not notice it.

- Support for aptX Adaptive. Further development of aptX; actually combines the capabilities of aptX HD and aptX Low Latency, but is not limited to this. One of the main features of this standard is the so-called adaptive bitrate: the codec automatically adjusts the actual data transfer rate based on the characteristics of the broadcast content (music, game audio, voice communications, etc.) and the congestion of the frequencies used. This, in particular, helps reduce energy consumption and increase communication reliability; and special algorithms allow you to broadcast sound quality comparable to aptX HD (24 bits/48 kHz), using much less transmitted data. And the minimum data transfer latency (at the aptX LL level) makes this codec excellent for games and movies.

– Support for aptX Lossless. The next branch of development of aptX technology, which allows you to transmit CD-quality sound over a wireless Bluetooth network without loss or use of compression. At the same time, audio broadcasting with sampling parameters of 16 bits / 44.1 kHz is carried out with a bitrate of about 1.4 Mbit/s - this is about three times faster than in the aptX Adaptive edition. Support for aptX Lossless began to be introduced in late 2021 as part of Qualcomm's Snapdragon Sound initiative, which is available on smartphones, headphones and speakers with a Snapdragon 8 Gen 1 processor and later.

— NFC chip. NFC is a technology for wireless communication over ultra-low distances, up to 10 cm. One of the most popular applications of this technology in smartphones is contactless payments, when the device actually plays the role of a credit card: just bring the device to a terminal that supports contactless technology like PayPass or PayWave. Another common way to use NFC is to automatically connect to another NFC-compatible device via Wi-Fi or Bluetooth: gadgets brought close to each other automatically set up a communication, and the customer only needs to confirm it. Other options are technically possible: recognizing smart cards and RFID tags, using the device as a travel card, access card, etc. However, such use formats are much less common.

- Infrared port. The infrared port looks like a small “eye”, usually on the top end of the phone. This equipment allows you to turn your phone into a remote control for controlling various equipment - just install the appropriate application. At the same time, we note that among such applications you can find an option for almost any device - from TVs to air conditioners, hoods, etc. Accordingly, the “smartphone remote control” turns out to be very universal.

— Walkie-talkie. Built-in radio module that allows you to use the phone as a walkie-talkie - for communication over relatively low distances without using SIM cards. Of course, for such communication you will need another walkie-talkie (or a phone with this function). The specific frequencies supported by the built-in radio module should be clarified separately; however, all phones with this feature operate in one or more standard bands. In practice, this means that they are capable of communicating not only with similar phones, but also with classic civilian walkie-talkies - provided they match the supported bands. The communication range is usually quite low; however, the built-in walkie-talkie can be very useful for tech in situations where conventional mobile communications are ineffective or unavailable. Typical examples of such situations are staying “far from civilization”, in an area of poor treatment, or traveling abroad, where roaming is expensive.

– Satellite communication. The satellite communication function is intended to send emergency alerts to rescue services in emergency situations. Smartphones with the ability to connect to satellite frequencies can communicate with emergency services in areas where there is no mobile network treatment. For better signal reception from satellites, it is advisable for the customer to be in an open space. At the stage of function formation, only ready-made requests can be transferred. In the future, it is planned to support full messaging via satellite communications, but a separate fee will be charged for them.

Inputs and outputs of the smartphone.

This paragraph usually specifies the type of charging and data port (most often it's USB-C), and whether the smartphone has a mini-jack (3.5 mm)(there are devices without it). It can also indicate the interface of the USB-C port up to the high-speed third version ( USB-C v 3), the location of the 3.5 mm jack (headphone output) and additional ports for a more specific purpose.

The main ports are used primarily for charging the battery, for connecting various accessories to the phone and for connecting the device itself to the computer via a cable. 3.5 mm port (mini-Jack) is intended primarily for headphones and other audio accessories, although other usage formats are possible. Here is a more detailed description of the different types of connectors:

— USB-C. A relatively new type of universal interface, a kind of successor to microUSB, which is increasingly used in mobile devices. USB-C differs from its predecessor primarily in slightly larger dimensions and a convenient two-sided design: thanks to it, it does not matter which side to insert the plug. In addition, this interface allows you to implement more advanced functions than microUSB — in particular, certain fast charging technologies were originally created specifically for USB-C. USB standard supported by this ty...pe of connector can be specified separately. Today the options are:

• USB-C 3.2 gen1. The standard formerly known as USB 3.0 and USB 3.1 gen1. Provides data transfer rates up to 4.8 Gbps.
• USB-C 3.2 gen2. The current name for the standard, formerly USB 3.1, then USB 3.1 gen2. The connection speed on this interface can reach 10 Gbps.
• USB-C 3.2 gen2x2. A standard (formerly known as USB 3.2) that delivers twice the speed of "regular" USB 3.2 gen2, up to 20Gbps. Unlike previous versions, it was created specifically for the USB-C connector.

— microUSB. A universal connector, which formerly was extremely widely used in portable devices (with the exception of Apple devices). It is less convenient and technically advanced than USB-C, therefore it is gradually losing popularity; however, there are still quite a few devices with microUSB out there.

— Lightning. Apple's proprietary connector used exclusively in the iPhone. It has a double-sided design that allows you to connect the plug in either direction. In modern iPhones, it is used both as a universal one and for connecting headphones (in 2016, Apple abandoned the 3.5 mm audio output in their smartphones).

— Original port. The one that does not belong to the types described above. Nowadays, such solutions are extremely rare — standard interfaces are more convenient and versatile, as they allow you to use not only "native" accessories, but also solutions from third-party manufacturers.

— USB A. Full-size USB port — similar to those used in PCs and laptops for connecting various peripherals. It has a similar purpose in phones, it is mainly used for flash drives and other external accessories (the specific set of supported devices should be specified separately). Usually, it is supplemented with a more traditional universal connector like microUSB or USB-C; in general, for a number of reasons, it is very rare.

— Magnetic connector. A connector that uses a permanent magnet instead of a standard plug system to hold the cable. Such solutions are used mainly in devices with water protection (see "Waterproof"), and most often — to charge the battery in addition to standard universal connectors (usually microUSB or USB-C). The main convenience of the magnetic connector is that it does not need plugs to protect it from water. It simplifies the connection and disconnection of the charger, and secondly, the wear of the plugs on standard ports is minimized — they do not need to be opened and closed every time you charge the smartphone. However only a special “native” cable is suitable for a magnetic connector; but if this cable is lost or broken, it may be possible to charge in the usual way, through a traditional universal connector.

— Mods contacts. Contacts for connecting special additional modules that expand the functionality of the device. Such equipment is usually found in some rugged phones. The modules themselves are usually a kind of "cases" that are put on the back of a smartphone; in such a “case” there may be, for example, an additional battery, a gamepad or even a thermal vision mod.

— Mini-jack (3.5 mm). A connector primarily used to connect wired headphones and other audio devices (such as portable wired speakers). Such a connection is extremely popular among audio accessories (and not only for "mobile" purposes); so finding headphones, a headset or speakers for this connector is usually not a problem. In addition, the 3.5 mm jack can also be used for more specific tasks — for example, connecting a selfie stick, a card reader or exchanging data with wearable fitness sensors and other specific equipment. However, such features are rarely used and require the installation of special applications, but connecting headphones is the initial function of such a connector, available by default. So the mini-jack connector is often called the "headphone output".

— Location of the headphone output. The 3.5 mm output described above in modern phones can be located on the top, bottom or side of the device. However, the latter option is generally less convenient than the first two, and therefore is rare. And the choice for this indicator depends primarily on how exactly you are going to carry the phone and which side will be used to connect headphones to it; For different situations, the options will also be different.

The capacity of the battery that the mobile phone is equipped with.

Theoretically, the high capacity of the battery allows the device to work longer on one charge. However, actual battery life time will also depend on the power consumption of the gadget — and it is determined by the hardware specs, the operating system, special solutions provided in the design, etc. So in fact, phones with capacious batteries in general have "long battery life”, however, the actual battery life can differ markedly even for two models with similar specifisations. Therefore, for an accurate assessment, it is better to focus not on the battery capacity, but on the operating time in different modes directly claimed by the manufacturer (see below).

The presence of water protection of the device; also in this paragraph, the specific level of such protection according to the IP standard is usually specified — for example, models with indicators IP67, IP68 and IP69 are classified as waterproof. The last two levels IP68/IP69K often coexist - devices with the “69th” protection rank are a priori protected according to the “68th” requirements.

The two digits in the IP designation indicate the levels of protection against adverse factors. At the same time, water protection is directly indicated by the last digit, but the first characterizes the level of resistance to dust and other contaminants. In modern mobile phones, you can find the following levels of protection:

5 — dust resistance (dust can get inside in small quantities that do not affect the operation of the device);
6 — dust protection (dust does not penetrate inside at all).

Lower levels of protection in mobile phones are not indicated (such device will no longer be dustproof, and there is no need to specify its specs). However, there are models that have an X instead of first digit — for example, IPX7. This means that this device has not been certified for dustproofing, although in fact the level of such protection can be quite high. So, in our example, moisture resistance of 7 means the poss...ibility of complete immersion in water, which means that such a case is closed very tightly from dust too.

As for moisture resistance, here the options:

— 2. The minimum level specified for mobile phones is protection from drops and splashes at an angle of up to 15° from the operating position of the device (usually screen up). Allows you to withstand moderate rain without strong winds.
— 3. Protection against drops at an angle up to 60° (medium rain with strong wind against the screen position).
— 4. Protection against splashes from any direction (rain with strong wind regardless of the position).
— 5. Protection against water jets from any direction (showers, storms).
— 6. Protection against wave impacts and strong water jets.
— 7. The minimum level that should be considered real water resistance. Allows you to endure short-term (up to half an hour) immersion under water to a depth of 1 m.
— 8. Possibility of long-term (30 minutes or more) immersion to a depth of more than 1 m, with continuous work in the immersed state. Specific depth and time limits may vary.
— 9. Protection against high temperature water jets (possibility of intensive washing with hot water under high pressure).

In general, a higher level of protection, on the one hand, provides an additional guarantee in case of adverse situations, on the other hand, it affects at least the price, and often also the dimensions and weight of the device. Also note that a waterproof phones can also be made shockproof (see below) — this is not necessary, but it is often found in models designed for use in extreme conditions.

Special shock protection provided in the design of the phone.

The specific level of such protection may vary, but at a minimum it allows you to endure falls onto a hard surface from a height of about 1 - 1.2 m without consequences. Many models also have more respectable indicators; These details should be clarified separately. Keep in mind that we are usually talking about the body; the screen may have other impact resistance characteristics, these depend primarily on the coating (see “Main display”). And if you need maximum durability, it’s best to complement the screen with a special protective accessory.

In any case, shockproof devices are designed mainly for users who often have to be in extreme conditions: climbers, military personnel, rescuers, etc. In light of this, such models are usually also made waterproof (see above).

There are also models with MIL-STD-810 protection standard. Initially, MIL-STD-810 is a set of specifications that establishes certain levels of protection for electrical equipment from environmental factors. The standard was developed to test military equipment for the US Army to ensure that it remains operational under a variety of adverse conditions. It imposes quite stringent requirements on the test subjects: the level of resistance of the product to impacts during falls and shakes is checked, vibration tests are carrie...d out, the operation of the device is tested in a wide temperature range, in the rain, in fog, under the influence of sand, dust, etc. However, the MIL-STD-810 label in “civilian” products does not always mean the highest degree of protection. This is due to the lack of strict regulation of testing. Thus, the most cunning vendors test the gadgets being tested according to literally one or two points of the program from an extensive list and often deliberately do not disclose which tests were passed. Accordingly, the specific features of such protection remain reliably unknown. The standard has been in force since 1962. Each new version of it is indicated by a letter of the Latin alphabet at the end. The further the letter in the alphabet, the more modern the version of the certificate. Since 2008, the MIL-STD-810G specification has been in force everywhere, and in 2019 a new edition of the MIL-STD-810H standard was approved.
