Fixed: iPhone battery drain issue post iOS 17 updates

I have seen multiple threads here regarding new iphone battery drain issues but no solid solution. I did some troubleshooting and found below steps which really helped with my iphone 15 pro max battery life.


I noticed “hotspot” was turned on and also “Call on other devices” post ios 17 update.

  1. I turned off hotspot by going to settings —— hotspot and switch toggle to off

2. settings ——— cellular——— turn off call on other devices.

in addition make sure your bluetooth is off when not in use. Make sure to turn off through settings and not just from control panel. Settings —— Bluetooth—— turn toggle to off.


this has immensely helped me with iphone battery drain issue and my iphone is holding the charge all day despite me playing games and spending lots of time on social media. Hope this helps

I also created a video about this issue but community guidelines prevent to post here

same here I have until January 16 to return my phone Apple support gave me the same options they gave you, I didn't try to exchange my phone for another, because I don't think that would solve my issue based on the community here, it seems like the issue is widespread. I have a problematic iPhone 11 that I could go back to, but I don't really want to do that. It's just unfortunate this iPhone 15 I have in my hand cost me US$1029 that's not cheap. I hope Apple comes up with a fix, but I'm not confident about it.

I thank you for the information, but I turned off all of that before I even set this phone up. I always do. Bluetooth included. I’ve been hacked many times on many phones (hopefully this one is safe so far).

also lately this phone is getting red hot even when not in use. My friend said her 15 gets hot and mine has been getting hot since I got it but now I am talking burning hot and I’m lucky if it lasts until 1 o’clock in the afternoon. I thank you for your attempt but I’m back to square one. I think we all got stuck if you want another truth.

I can tell you what it has to do with it! When you live on a budget, a new phone is a big extravagance.

thus, when the phone has an obviously common issue that affects its performance and you cannot use it half the time and you have to spend your time on something like this to see if somebody out there might know if there’s a fix that is why the two go together. Every year comes out with a new phone before Christmas people run to get the new phone only to find out it’s worse than any of the predecessors. I’m sorry but I think if you think about it and pray about it, you might understand it better.

My opinion only of course because we got stuck! My SE my 11 and my 12 had none of these problems and they did not get hot as a red poker while sitting in my pocket not being used.

Sometimes you have to use Bluetooth and for some people like you all the time. You should not have to rearrange your usage of what has become your identifier in life and possibly work because Apple has made a bad product.
