Holy crap. Series 4 on the most recent beta. Battery drops to 20% left after 6-8 hours, and I don’t even do anything on the watch but look at the time. Anybody else experiencing this??

Not me. I have the Series 3 42mm and could easily exceed 2 days on a single charge. Beta 5, 6 and 7 have all been great in regards to battery life. Battery life on my watch is actually slightly better than watchOS 5, which surprises me for being on a beta of a new version of watchOS.

On beta 8 now and seems like it’s done settling in. This morning I unplugged at 03:35 and was at 100%. It is now 06:24 and still at 100%, and I’ve been walking a lot this morning (my job consists of a good amount of exercise).

For you, I recommend unpairing and repairing your watch. If that doesn’t work, maybe the next update will fix your issues but I think unpairing and repairing will fix that. But, you’ll find out the actual result when you do it.

Yep not me either. AW4 Nike 44mm.

On WatchOS5 my watch would come off charge at 7am and go back on at midnight with about 15% left (I do about 1 ½ hours workouts in the day).

On WatchOS6 since beta 6 and my watch is 35-40% at the end of the day - so much better than OS5!

I think maybe a re-pair may fix it.

I’ve been having problems with my AW (series 4, 44 mm) battery for about a month, when I was on WatchOS 5 and iOS 12.

Re-pairing didn’t fix it so I tried updating to the betas, without any luck. About 8% battery loss every hour, good for just 12 hours.

Today I thought I saw some improvement, with 16% left after 12 hours. And right then, when I was looking at the screen, the watch turned off and the “charge now” (the icon with the charger) appeared.

Sending feedback right now.

The thing is, I have been completely unable to fix the battery issue. I come from Android and my Huawei Watch 2 with LTE was sluggish and less useful (it could do the same things, but in a more cumbersome way). But I had never problems to make a day with it from bed to bed, and that was with the screen always on.

I didn’t think this kind of things happened with Apple hardware (it started with non beta software). I guess grass is always greener on the other side.

Maybe you have a worn out battery. It happens.

Same story with me but OS 5.3. After the update the battery lasts max 8-9 hours even on airplane mode. I tried every possible solution (unpair-pair, erase all contents, switch off notifications, wifi off, bluetooth off-on, checked workout, paired with a friend's iPhone), everything. I visited local apple retail store that they are official apple retails in Greece and their reply (twice) that the watch is ok and nothing came up on diagnostics by the technicians. They also told me that they send it to apple in Europe (??) and nothing came up.

Now what???

Any suggestions are appriciated!

Did they run any battery related diagnostics?

I suppose so! They first run some random diagnostics and then they kept it for a week or so and they send it to Apple in Europe somewhere to check it too. According to them nothing wrong was found but the watch still lasts max 9hrs.

Try removing a of the third party apps from the watch for a day and see if that helps battery life. I’ve heard of people saying apps got ‘stuck’ and ran continuously on their watches. If you get better battery life, try reinstalling them one at a time until you find the culprit (or maybe it goes away entirely when the app reinstalls.)

No third party apps installed. I tried that too

Is your iPhone on iOS 13? If so, my battery life decreased after I updated my iPhone. Now on watchOS 6 beta 8 and the battery life is better than 5.2 & 5.3.

Here are my steps I use when I get unexpected bad battery use

  1. Check the battery usage vs standby. On the watch app, General>Usage. My usage time is typically 15-20% of the standby time. When I have battery issues, that percentage jumps to 40-100%
  2. Check which apps have Background App Refresh turned on. I have them all of except the ones that truly need it on.
  3. Restart
  4. If that doesn't help, I restart both the aw and the iPhone.
Rarely have to go past step 3

This was one of the first that i checked. Usage time is just a little ie 10-20% of stand by. Restart didn't work and i tried all the ways (iPhone watch and the opposite)
