Apple Watch sudden battery drain?

This is a follow up to my previous posts. I found that my iPhone and Apple Watch were still draining faster than they should.

Reviewing the diagnostic logs from my iPhone and watch, I found TrustedPeersHelper still taking a lot of CPU on both devices. My mac has been fine, but something still wasn't right with my other devices.

So, this time I ran this terminal command from my mac: tpctl reset

I was then forced to login to iCloud on my mac and iPhone, but ever since my watch and iPhone are not running hot. Yesterday, I wore my watch from 7 am to midnight, and I still had 60% remaining on my watch, and 70% on my iPhone.

The "tpctl reset" resolved all of my battery issues!

If you don't have a mac, I'd recommend calling Apple or going to an Apple store. They must have a way to do the equivalent of "tpctl reset" on your behalf from their side. I hope this helps everyone.

Ok, using iWatch Series 4 and iPhone XS. Watch iOS is 6.1 and Phone is 13.2.2. What I noticed over the last three weeks since upgrading the systems is that my watch would only get about 8 hours before I have to recharge. Ironically, phone is just as bad as the watch. So, I Reset all settings on phone and kept all content and unpaired watch and re-paired watch as new.

So, today, watch is at 98% after taking off charger 2 hours ago and phone also seems back to normal usage.

Note, I walk in the morning and for a 30 minute walk the watch would drain about 8% during those 30 minutes. Phone would also drain like the watch. Today, watch was at 98% after the walk and phone was at 99%.

Will keep you posted as the day goes along.

After disabling Analytics, my watch is back to normal. It's been on my wrist for 9 hours and I still have 70% battery remaining! It's tip #2 in this YouTube video (you can stop at ~ 40 seconds in if you only want this one tip).

Finally tried the following steps in these threads and posts as I had a Macbook Air (Catalina 10.15.3), iPhone 11 Pro (iOS 13.3.1), iPad (6th gen) (iPadOS 13.3.1), Apple Watch S4 Wifi (watchOS 6.1.2), and Apple TV 4K all logged into the same Apple ID and was able to confirm this "TrustedPeersHelper" process running wild on the Macbook and appears to be the culprit of the crazy battery drain.

After this, TrustedPeersHelper is utlizing 0% CPU consistently on the Macbook and seeing less than 2% drain per hour on the Apple Watch (all default settings) with normal (watch-like) use during the day and silent/do-not-disturb/theater mode on at night.

Hi Matt,

I had the same problem. Noticed the walkie talkie function was switched on - on the watch, so turned it off. Powered off the watch (Series 3), powered off the phone, (XR) Re-started the phone and when fully back on, re-started the watch. It sorted the issue with me. Some have done this and made some difference others had no joy. I believe apple are working to sort the issue but try this as an option.

Cheers

Much better now since I upgraded to 6.1. I don’t have a full day yet but woke up yesterday after sleeping and starting the night with 90% woke up with 30%. The update arrived and it took me a while early morning to charge it just to update it. After update charged the battery to 79%

Updated at end of day only down to 40%. I had already worked out by then so this is just a day at work.

put it down for a full charge before going to bed. Big thing I’ve noticed with this battery drain is losing over 30% (60% that last night) just sleeping. After a full night sleep, lost only 1%.

that’s a huge improvement.

I’ll report back at end of day to see with a work out and normal days use what the consumption is but highly recommend you all update to 6.1

I turned off a bunch of background refresh apps I don’t use and turned the music playlist syncing off, did the restarts. And had a great response battery life seems to be about what it was before if not better, I wore it for 16hrs and went to bed with it at 68%. Good luck everyone

After a hard reset and setup as new, it took maybe a week and a half before the battery came back to normal on my Series 5 LTE. Now getting about 24hrs from 100%-0. Workouts are still a killer though.

Using pretty much the defaults with background app refresh, AoD, Hey Siri and Noise detection. Only thing turned off is Walkie-Talkie.

I have a Series 2 running WatchOS 6.1 - I was having major drainage issues (dead in 3hrs) - I think turning off all Podcasts and Music from auto downloading to my watch is what fixed it for me. The day I did that, watch went back to normal - well, as normal as the Series 2 is these days!

I had the same problem as everyone else after a recent upgrade to the latest IOS and WatchOS. I tried everything mentioned here (power off and on of the iPhone and Watch, unpairing and re-pairing, etc.). Nothing worked. I was getting ready to go to the nearest Apple Store when I tried the power off and on procedure one more time, and then I also turned off Bluetooth in Settings on my iPhone. I turned Bluetooth on again in a few minutes and let the iPhone reconnect to the Watch. I don't know why, but this worked! It has now been three days, and still no more rapid battery drain. Hope it holds.

Phone is an iPhone 8 and watch is a series 4.

In my previous post I thought I solved the problem. That lasted about 10 days. I had occasion to reboot my iPhone, and the problem came back. This time I did go to the Apple Store. We went over all the things I tried. It seems that Apple is aware of the problem. The only thing I didn't do was to restore my watch as new when I tried the unpairing/repairing. When I got home I tried this and it did work. Been working for about 5 days now. I don't know if my problem has been fixed now, but at least I have a case number with Apple Support (my warranty runs out today, but they said that was not a problem if the battery drain still persists). One thing they did ask is, when I got my series 4 watch, did I set it up as new, or did I restore it from my previous series 3 watch. I couldn't remember, but if I did a restore maybe that's part of the problem. In any event, I would recommend anyone with this problem to got to an Apple Store and open up a case file.

A previous poster already brought it up, but you folks should look into the diagnostic logs for the watch (see Watch App, General>Diagnostic Logs). For me it said ‘TrustedPeersHelper’ and I posted the solution here: https://discussions.apple.com/thread/251111200

if you look through the logs, see if there’s a process with absurd CPU time.

60% battery remaining after 14 hours (Apple Watch 4).

I completely agree with your frustration there and that Apple should have a more rigorous software quality control system in place. However, that being said, you probably want to get a resolution for your problem.

It might not have anything to do with the problem which I had! I would suggest looking into the diagnostic logs to see if there’s any process that is causing an unusual high number of CPU hours. Also, see if the battery drains that much if you place the Watch in Airplane mode for a while and simultaneously turning off Bluetooth on your iPhone (no Internet connection for your Watch). You can also try other things like turning off notifications completely, turning off all background processes, and setting up the watch as a new watch and seeing if the battery drain persists.

Good luck!

The hard reset didnt work for me. It was the unpairing of the apple watch and then repairing as a new device that worked for me. I had no issues until 6.1. Its been stable for the past week so far.
