Popular questions about Samsung Galaxy Watch8 40mm LTE

Verified 2 september, Serhii Shkurupii

How does the 40 mm Samsung Galaxy Watch8 differ from the LTE version?

The current 40mm version connects to your phone via Bluetooth and Wi‑Fi. For eSIM and 4G mobile internet, you need the 40mm LTE or 44mm LTE version — it’s more convenient if you want to leave your smartphone at home.Source:Specifications

Is it worth switching from Galaxy Watch7 to Samsung Galaxy Watch8?

The upgrade is justified if you need Running Coach, vascular load assessment, an antioxidant index, and Google Gemini on your wrist. The case is thinner, and maximum brightness has increased from 2,000 to 3,000 nits, but the previous generation’s core workout-tracking capabilities were already strong.Source:SpecificationsExpert reviews

Will I have to charge the Samsung Galaxy Watch8 every day?

Generally, yes, especially with Always-On Display. In a typical scenario with overnight wear and a GPS workout, the watch lasted about 26 hours with AOD and up to 39 hours without it; charging takes approximately 64 minutes.Source:SpecificationsExpert reviews

Which smartphones are they fully compatible with?

Samsung Galaxy Watch8 requires a smartphone running Android 12 or later with at least 1.5 GB of RAM. You can also connect a phone from another brand, but some advanced features, including certain AI insights, snore tracking, and gestures, are available only with Samsung smartphones.Source:Expert reviews

How useful are smartwatches for running?

Samsung Galaxy Watch8 are suitable for regular running: dual-frequency GPS recorded routes accurately in testing, while the heart rate usually differed from the reference watch by no more than 5 bpm. Running Coach builds a plan after a 12-minute test, although its workout prompts may seem repetitive.Source:Expert reviews

Will the 40 mm Samsung Galaxy Watch8 be suitable for a slim wrist?

Yes, this is the most compact version in the lineup: the case is 8.6 mm thick and weighs 30 g without the strap. This format is more comfortable for a smaller wrist and for sleep, but the screen here is smaller than on the 44 mm version.Source:Specifications

Can they be worn while swimming and in the rain?

The Samsung Galaxy Watch8 are suitable for swimming and everyday contact with water: IP68 protection and 5 ATM water resistance are specified. Sapphire glass also provides better protection for the screen against scratches during everyday wear.Source:Specifications
