iPhone 12 Pro Severe Battery Drain

well the 14.2 update didn’t provide any relief. Apple told me to backup, reset to factory and then restore. Also useless. I, like many of you see a constant drain of battery while on wifi and idle.

Hi,

I have had the same issue in the UK. I returned my first device and the second is the same. Had a call with the Apple Tech team, and they advise I did a complete factory reset from iTunes (not a back up) and download all your apps again - so basically you are starting as if it is a brand new phone - but they made no difference either.

I am still getting around 5 hour basic use (and that just social media and emails) in a 24 hour period with the rest of the time the phone is on standby before needing to recharge . It drains 15-20% overnight - and everything background is turned off. (and that is without 5G as we do not have it where I Live). I was told if this didn't work the only other thing would be a new ID - but cant see how that would work , especially with other having the same issues

There is obliviously a bigger issue here, as I didn't have this issue with my 11, which lasted a few days . Come on Apple - how can you still be having this issues 12 phones in !

Are you on 5G? The 5G radios use significantly more power than the LTE radios, no matter what the device:

It isn’t an indexing issue. I think it’s related to the new modem.

If so many of us are reporting this, this has got to be an actual issue. I suspect it is a software thing since the phone works pretty good when I’m actually using it!

How odd...

So there is a constant rapid drain on the battery while idle. You can see that here. Phone was on wi-fi, no activity

I wonder when apple will do something about this - clearly an issue here

14.2.1 made no difference for me
