iOS 16 Battery Drain Thread

[rob2bob]

Hmmm your experience of battery drain and being warm is similar to mine. Did you delete the 3rd party app emails too?

I deleted all mail accounts (5 of them) within the iOS mail app as that is the only source of mail on my phone. Today battery still at 62% from the 100% charge ... looking good 36 hrs on! (Update: 43 hrs now and still a respectable 40%.)

I’m glad and surprised by the battery on 16.6 public release. My 13 P, with 88% battery health managed to work for 7 hours and drain 55%. I see that just apps that are using gps and full screen brightness drain the battery faster, but i think is normal.

Just did this last night. I even did my 3rd party ones too. Let’s see how this goes!

After upgrading from iOS 15.6.1 to iOS16 my phones battery draining much faster..
Specially last few months it's noticeable..
It's really heartburning for my 13 pro max 😑😑😑

Some versions on iOS16 (and other iOS versions too) seem to have affected battery life, but it might not only be down to iOS issues. 16.6 seem to be one of the better in terms of less bugs and battery drain.

Have a look at some of the advice in the thread.
I updated to iOS 16.6 recently and reinstalled the fitness app (I don't use it) and its a massive difference. The battery life and hot phone issues are gone. Not sure what sorted it, maybe its a combo.
The only issue I have now is that "find my phone" are using my GPS all the time, still doesn't seem to have an impact on the battery.

So my advice is to jump on 16.6, you should do it anyway if you have a look at the security issues that it fixes.

I just got inspiration from this. But without deleting my email’s accounts I setup data download in manual for all my accounts with the exception of iCloud. Probably your intuition is right. Push and auto check for emails is probably another battery drain culprit.

If you want push mail though (as I do) I leave it toggled on and my solution is working for now still!

Push drains battery no matter what device/OS or service you are using.

True. And clearly depends mainly on if mail is actually being sent by those push accounts. The Fetch ones eg Gmail can be more battery hungry so arguably leave those toggled to manual if one is concerned vs automatic.

But for me it was clearly an issue when Mail was running almost 24/7 in the background as it was before my fix. I’m now getting 2 days+ out of a full charge easily (push mail still on) whereas before I would not even make a day. No Mail running in background showing now. Result.

Welp, it didnt really fix my issue...

I'm going to try a 'reset all settings' and see if that does the trick.

Maybe reset network settings first. Less drastic.

completely and you are no adding them back??
I couldn't do that, I need my emails

Yes. As per earlier post. All added back after.

Well! It seems Reset All Settings did the trick! Must slower battery drain this time. And this is with Background Refresh turned on too! I might not mess with anything from here on out to keep it like this.

🔋 Battery life update.

Pre-ordered iPhone 14 Pro Max.

Battery life has been degraded to 91%. Single charge - Averaging roughly 6 hours or so.

Lot's of posts and youtubers are saying the same. Kind of seems unacceptable. My iPhone 11, almost 4 years old, still has 84% battery and I use it about 4 hours a day, used to be closer to 6.

Last update killed my 14 pro again, came good with the previous one from the previous one lol

+1.

Why does my phone get so hot when applying an update? It’s apparently well-known that heat damages batteries. Perhaps the update could be done more slowly to keep the device cool?

The other thing is the X days of settling down after an update. Why would spotlight re-indexing have to occur after every update? That is, why can’t they find a way to keep and re-use the previous index?

The whole battery life/update situation has gone on far too long and is spoiling the iOS experience, in my view.

Me too. My 14 Pro Max battery has been notably draining much faster with iOS 16.6, even though the maximum capacity is still 100%.

On the first few days of the update, the update actually happened to improve battery life for me. Then for some reason, it became much worse later on…

Here’s what I got on the first day of the update. I ended up the day with 50% left down from charging to 92% the previous night. And I’m an average-to-heavy user. Such an impressive battery life, right ?

On the other hand, here’s what I’m normally getting these days on the same version with the same usage. It has been notably draining a lot faster and I’m not sure why.. it hasn’t been so great.

My phone always gets really hot when I install software updates as well. And starting from iOS 16.5.1, battery life hasn’t been so great for me..
I hope we see some improvements for battery life with iOS 17.

Battery Life has been trash on my iPhone 14 Pro Max 1TB (Unlocked).

I certainly believe iPhone 14 lineup in battery life is not that great. I feel like iPhone 13 Pro Max battery was a lot better compare to this iPhone. I really hope a better battery management system takes its place in the iPhone 15 Line up.

As you can see below barely push 5 Hours throughout the day. I was also on Wi-Fi all day. 0-100% Overnight charging. This is just unacceptable!

Glad to see the return of your avatar pics!

I'm not seeing any battery issues at all on my iPhone 13, thankfully.
