Google Pixel Watch 3 vs Huawei Watch GT 5

“GT5 runs huawei own OS and no access to any google services - so not an option per what you are looking for. In terms of wear os watches you longest battery life is: technically the ticwatch atlas / enduro - standard is up to 5 days, but then extensive use of lcd screen and turning off features (essential modes) can extend it out further - but not a fan of their support or their durability (been issues with both). Then next best is OnePlus Watch 2 (up to 4 days) or Watch 3 (up to 5 days) - however can extend out to up 16 days by switching into their own os - however this takes away all the google services (incl nfc pay) - however only takes about 1 min to reboot back into wear os. Mixed use will generally give you between 5-12 days. Samsung GW Ultra - up to 3 days. For the rest you are looking at 1-2 days depending on model and size of model. Alt: no google services, but do offer their own payment system: Garmin with Garmin Pay; and Amazfit with Zepp Pay (note this is pretty restricted depending on country). For GT5 note that it looks like Huawei may be doing a deal with Curve which then may give them a payment option in some European countries.”

“In fitness and health tracking like sleep ecg makes it more precise usually - but in second it really depend on manufacturer, as i found pixel watch 3 with ecg less precise than apple watch se2. And yea i did this testing multiple times (sleeping, sport tracking..) and weared them in same time (usually one on one wrist, switched it between left and right too, foe be sure about results.”
