Huawei Watch GT 4 vs Huawei Watch GT 5

“SpO2 is usually around those values, to check if it works properly you gotta see if its able to detect a drop in your oxygen saturation when it happens, which is not a scenario you get in your everyday life. I sincerely don't care much about SpO2 parameter, if I'd be in need of checking mine or someone else saturation I would never use a watch. Yet, in a YouTube video the reviewer went on a plan and measured his blood saturation there and GT4 overestimated all values (giving ~98/99 when his saturation dropped due to altitude). Once again, don't care about this parameter but I wouldn't trust that watch in recording it. I'll use this conversation to ask you a few questions about the GT4 if you don't mind, I think that this will work as well to understand if buying it or going for the balance. - I see you answered about the altimeter, thanks for that! Does it also track staircase steps? - is there anything like Readiness? - how's the gym app? What does it do, which infos and functionalities gives? - does the watch allow playback control of Spotify and tidal? (I'm more interested in tidal) - how's the compatibility for no-huawei android phones? (in case you got one). Do you miss out smth? If you can answer some of these question I'd really appreciate!”

“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.”
