Apple Watch battery draining fast after 6.2.1 update

Here's how I ensure my watch never runs out. Every morning, I put my watch on the charger until it gets to about 99%, where it always sticks for an hour or more, often never reaching 100%. At that point, I reboot my watch, and it comes up with 100% battery every time, immediately. After that, the watch acts correctly. I would tell this to Apple but I really have to clue where to send the information. Hopefully they read this forum occasionally. I believe this shows the problem is in software.

Hey there Comus01,

Have a good one!

similar issues since updating last week.

Started happening during the last week after I

updated to latest WatchOS 6.2.1 (Model A1978 44mm S4 Nike).

My watch will just be dead randomly when it should have plenty of life

left. Sometimes it will give the red/dead charge indicator on screen

when I attempt to turn it back on. Other times it will be dead, I turn

it on, get white apple logo, and then it acts fine for a couple mins,

then dead again.

My watch seems to be totally fine at the higher charge levels (over 70%), but once it

dips down below, it just turns off randomly.

Super frustrating. Worried this bug will snap my 700+ day 3-ring streak.

I got my S4 around release date. It's approx 17 months old. Never had an issue like this before with any other update. Have tried soft restart, and force reboot (both buttons 10 seconds), and restarting my iPhone (both ways, soft and force).

Have not yet attempted unpair/repair...

Mine is dead in 5 hours. Just talked with Apple support and they did a battery diagnostics test and it came back with no problems. Since I have apple care tho, they’re sending me a new one. They said it shouldn’t be draining that fast, especially after I did a factory reset on It.

What is "this" that worked for you? I'm seeing a lot of vague posts here. For me, the thing that works is to make sure my watch says 100% charged when I take it off the charger. If it sticks on 99%, I reboot the watch with the two side buttons while still on the charger and when it comes back online it always says 100% and works fine for that day. I do this every day because it works so why not?

Unfortunately my series 2 is still having issues. I did chat with support and they recommended I do a phone call next. The tech said it could be my battery. My watch was fine before the update. No issues with charging or draining until after the update. It was immediate difference. Now it’s worthless. I’m beyond frustrated. I bought a new charger like they recommended. The watch will say it’s 100% charged, but once I put it on my wrist, it’s dead 2 mins later.

You're welcome. It has been more than two weeks and I no longer have this issue. It does look like the "charge then turn off" method worked.

I have the exact same issue with my series 4 with cellular. I have had version 2,3 and 4 of the watch and never had a problem with updates until now. Have shut off and turned watch back on several times over the last few days. Like you, no new programs or changes. This is truly a bad update.

Dear friends!

I have a Series 3 that was working perfectly until a week ago... I updated to 6.2.1 and now the battery drains in half a day... Tried to reboot, reset and hard-reset... Nothing works!!

Does anyone know what to do?

Thanks!

Dani

Hey do u got any solution for this issue.... I stopped using Apple Watch as i was having same issue , like its getting turned off automatically even when the battery is fully charged... help me to get rid of this problem

I have a series 2 and since the update I am having same issues. I haven’t been able to use my watch for more than 2 hours. Previously with workouts, using apps, etc., my watch would last at least a day and a half. It turns itself off randomly and won’t turn in until I put back on charger. Then it turns on saying I have 100% battery. Take it off and put on, 1 hour later I’m at 20% then it turns off again. Other times I put on charger and it won’t charge past 65%. Before update it charged and worked great. I’m so frustrated. I was told I could send it in for $250. Really Apple!!!

Yeah, this thing has a way of returning in a couple of weeks. It would be great if in a month you can let us know how it's going! I have "fixed" this problem by resetting phone and watch a few times and it always comes back. I have not done a factory reset of both devices yet. I guess I'm incredulous that such a horribly destructive procedure is necessitated by a bug that Apple is not even acknowledging as real from what I can tell.

After a few months having this problem (posted here before), and after visiting the Apple store where I was said that there were no defect in the battery, my watch died and it's only showing the "snake screen of death".

So, the warranty is only for one year and I'm screwed. Worst purchase ever.
