Hi all and thanks for posting regarding the battery issues of 6.2.1 (17T530)
I’m now on my 3rd Apple Watch 5 that’s been kindly replaced by my cellular provider EE and all watched have had this diabolical issue of battery drain .. all of the updates (6.0, 6.1 and now 6.2.1 (17T530)) have had terrible battery life issues (normally 8-10 hrs max with all the new features turned off including 4G cellular and very minimal apps ) and nothing has resolved this issue (on all 3 watches) also I’ve unpaired both Apple watches and iPhone and set all of them up as new ... I’ve also noticed a big battery drain on my iPhone overnight if wearing the watch to track my sleep and when wearing the watch over night with 8 hrs sleep the watch is completely dead when I wake up, another concerning issue is the battery charges up silly fast and then sticks on 96% for over an hour and I’ve had occasions when the watch reaches 50% it’s asking my to place the watch onto the charger as low battery is indicated ... I really don’t know what Apple are thinking About but they seriously need to get this issue fixed and sorted for once before I switch to Android just so I can have some reliability in just battery life reinsurance ... everything I own is an Apple product (iMac, MacBook Pro, HomePod, AirPods, PowerBeats3 Apple Watch 5) as I like to have everything linked but it’s getting to the stage where I feel Apple just does not care about its customers anymore and now this issue regarding the Apple watches battery life is pushing me further to the Android and windows end of the Spectrum as Apple products have started to behave like something that you buy From a cheapie Sunday market and as unreliable.
i do hope that Apple are listening to us and reading and taking note of what we are saying as I can see a lot of people vanishing from Apple products and sadly I’ll be one of them
