watchOS 6.2 draining battery fast

I have an Apple Watch Series 4. It has always had good battery life. I usually go to bed at the end of a full day with greater than 30% battery left, sometimes greater than 50%. I updated to watchOS 6.2, and next day my battery was dead by the middle of the day. I tried turning off and on, but it didn't help. I tried erasing the Watch and reinstalling the OS. Seemed back to normal the next day. But every day since then, the battery life has gotten worse and worse. It can no longer make it through the day.

i saw on another post that bluetooth stacks is corrupt, so i’ve turned off my bluetooth for now and left in wifi. use the bluetooth settings in your watch to turn off bluetooth. My watch is at 100% since my last charge at 9am. if it makes it through the night, then the problem is at least isolated. what to do from there is anyone’s guess.

Hey Everyone. Today is 5/14/2020

A temporary solution worked and for the first time in weeks my watch didn't just shut down pretending it has low battery. From my watch I went to settings - bluetooth - and turned it off.

Another person posted he was convinced after reading the log that it was an issue with the Bluetooth Stack. Now I don't claim to know what that is and what it does or how to fix, so my hunch was to turn it off. It worked and I turn on bluetooth for just a minute in the evening so that my health data can populate to my phone.

Hope someone or apple can post a fix for the bluetooth stack.

Hi all!


I managed to fix the issue by going into Health app and delete old data from old devices as described. Now my battery level drain is back to normal with being about 77% in the evening at 8PM, started using the clock at 6AM. It seems there might have been a lot of data being transferred back and forth between the watch and the phone?

Well this might have fixed it. After repeatedly resetting watch, clearing data, turning EVERYTHING off one thing at a time, unpairing, repairing, talking to Apple support... nothing worked. I could literally watch the battery drain before my very eyes. I deleted years worth of health data and then reset watch and repaired I’m back to normal battery usage. Series 2, Watch OS 6.2.5, iPhone XR iOS 13.4.1. Whew...I really did not want to buy a new watch. Thanks!

Well...It didn’t fix it. Yesterday I took my watch off the charger at 7 AM and 4 PM it was down to 25%. Last night I turned off all background refresh except for Messages phone and WhatsApp. Today I took my watch off the charger at 7 AM and at 2 PM it was down to 11%. I did pretty much the same thing today as I did yesterday. Background refresh getting turned off completely for tomorrow. This sucks. And the poor battery life happened out of nowhere. What happened on Monday 5/18? I was looking at the logs and see bugType 211 in almost every one. Here is one occurrence, though there are many variations...

”{"os_version":"Watch OS 6.2.5 (17T608)","incident_id":"9FC8CBA8-7BED-46A2-B878-D3EA4951F4FC","crashreporter_key":"7db539e26d419f0fb9e079bdbee00af9699a3ec0","timestamp":"2020-05-24 21:19:26.38 -0400","bug_type":"211"}

I’ll call Apple again tomorrow.

I can confirm that I had BIIIG problems with the battery life on my watch, 4 series LTE after upgrade prior to 13.5. It was down to 20% after lunch. But since I went inside the health app on my phone, pressed my profile, devices and deleted all old devices, the battery is now the best again. In the evening it is down to maybe 75%. There was definitely something weird going on with old data being sent between the phone and the watch.


I have also now upgraded to 13.5 without any issues being added.


Health -> Profile (your portrait) -> Devices (integrity section) -> Delete any old unused devices

I think everyone is in agreement that it is a software issue vs hardware. My watch 4 was suffering the same as everyone else until the latest 6.2.5 arrived and now my watch is working as good as new and hopefully Apple will release another update soon.


It would probably help Apple if we indicate watchOS and watch series when posting.


watchOS 6.2.5

Series 4

Update corrected battery issue.


May 25, 2020 3:39 PM in response to JanisG1

And then today… 7 AM off the charger background refresh turned off. No 3rd party apps running. Health data capturing turned off. Deleted cycle tracking app… Why the **** that should be installed by default is beyond me. 5:30 PM 10% battery. Did the same thing I do every day. Cripes! My Apple Watch is now officially… Just a watch.

Series 2 watchOS 6.2.5 iPhone XR iOS 13.4.1

problem started all of a sudden way after I installed 6.1.2. 6.2.5 made it worse. It’s got to be something in the communication between phone and watch. I wish I had paid attention to when I went to 6.1.2 and 13.4.1. I do it manually but I will start logging it.

I had this issue, I deleted all the watch profiles that was backed up, did a full delete and didn’t back up by saved profile.


I did new Watch setup and the latest update came a few days later.


Before the drain started, I would go to bed rat 40-50% and with battery drain it weighs die before 8 hours of use.


My watch is back to normal now and last night I put on the charger at bed and it was at 50% again.


Something fixed it.... Good luck!!!

May 28, 2020 7:22 AM in response to Sei Shin Ryu

Clearing the watch is voluntary and this is the first time I tried since the first watch because I was concerned that I might have had a hardware issue and I was trying to isolate the problem - 6.2.5 on Watch 4 fixed whatever bug was crawling around.


it is not acceptable that you have to wipe the clock with every update ...
