WatchOS 7.5 battery drain

Anyone else having a horrible battery life on the latest watch update? I have the series 5 on watch OS 7.5. Since the update my watch won’t make it 16 hours.


Before the update, I would be able to go to bed with my watch at 100%, use it for sleep mode and wake up alarm. Exercise in the morning for 30 minutes and go on my day. At night I would still have 20-30% battery before charging it. 

Doing the same routine, 2 days in a row my watch doesn't make it past lunch. I do not use the always on display function either.


Last night I reset my watch and restored from backup. Charged to 100%, went to bed wearing it, woke up this morning to 70%.


Hope a new update comes fast or wearing the watch is pointless with this terrible battery drain.

I’ve had the same issue.


After a week trying different routes, I’ve found what has worked and that is turning off the environmental sound measurements functionality in Privacy at least until Apple fixes the bug.


It looks like the functionality is running constantly in the back taking too much power, since the battery drains at a constant pace.


Hope it helps others!

Same. If I add exercise into my day I’m having to charge the S6 3 times a day now, before update it was once a day and no where near dead. I’m very frustrated, this update has made the watch a very bad experience. Been a user since the original and this is the worst the battery has ever been in this entire time.


Was perfectly fine pre update to 7.5.


I tried restart and reset and nothing is working to fix it.

Facing the same issue here. I did a restart of watch & phone - no use.


already apple watches battery is pathetic when compared to other smart watches with this bug, it is simply not usable !!


this is not acceptable for a premium grade device such as Apple Watch. All these things should have been tested before they release the software to masses.


fix this ASAP, apple !!!

For the last 24 hours or so, my watch has behaved more normally. I didn't change anything, which makes me wonder if there was some app update that fixed it. I don't trust it yet since this is the first time since the 7.5 update a couple of weeks beforehand. I have no idea which app it might have been, if it was even an app update that did it. There is a long list of updated apps listed in the App Store.
