Battery drain in iOS 14.7.1

All-

I did eventually notice improvement after resetting network settings. I had previously posted I didn’t notice a change. It just took a couple hours after the reset. I also did a total factory reset and set up my phone as brand new by connecting it to my MacBook Pro. I probably didn’t HAVE to do this, but I figured, why not? My phone’s battery usage is now superb. (iPhone 11 Pro Max 256gb)

I went to an Apple Store yesterday. I was told 95% battery health was too good to replace the battery.

They told me to do another backup then erase followed by restore from back (using iTunes on a pc).

This process took at least 4 hours so it was too late to determine if there is any benefit from this enterprise.

GUYS I THINK I FOUND THE FIX.

I reinstalled iOS in my iPhone.Here's the steps for you to reinstall the iOS with your Mac-

So please connect your iPhone with your Mac first, then Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then, press and hold the Side button until you see the recovery mode screen.

Then on your Mac, you will get the option to restore or update, choose Update. Your computer will try to reinstall iOS or iPadOS without erasing your data.

This has worked for me, Battery life is a lot better.

Also I don’t know how to reinstall with a Windows computer but I am sure the steps are online.

I am facing the same issue. I have an iPhone XS Max with 85% battery.

before updating to 14.7.1 I could last a day with a single 30 minute charge during the day.

But updating to 14.7.1 is draining the battery like crazy! Now I have to charge it 2-3 times a day!!

I'm using a iPhone 11 pro max and after i have updated the IOS to 14.7.1, my battery drained so fast that i can't even use my mobile much when I'm on the road or outside of my house. Would there be a fix coming out soon? otherwise, it will be so inconvenient to me... :(

I have just updated my iPhone XS Max with 14.7.1. My battery is draining fast and the signal of my phone is worse and when I'm connected to my home wifi it's running slow.

My wifi is fine on other devices as I'm getting 200 mbps

It actually is much worse. I’m having the phone plugged in and watching Amazon Video, and the battery doesn’t charge! What have you done Apple? I don’t want to go through the pain of downgrading but seems this is the only option for now. Resetting Network setting didn’t help.

On iOS and iPad OS 14.7.1 I am experiencing increased background usage even though background app refresh is turned off. I also got the message saying that the device was being used more than usual after the 14.7.1 update.

I don’t want to update system to 14.7.1 but I had to do that cuz mobile data stop working for no reason, now I have battery issues #apple #battery_bugs"

Michal ~ What model of iPhone is it?...

Does it still have its original battery?

And what's the Maximum Capacity % here?...

My iPhone 12 Pro Max is only 4 months old, the battery health is at 100%, but the battery life of each charge is significantly shorter than it was before the IOS 14.7 update. The battery was lasting the whole day since I got it, but not anymore. It’s very disappointing. A fix should’ve come through already.

Yes batteries can go quite suddenly. If you read my user tip you will have seen my own battery went quite suddenly with 83% "health". People have been blaming the last thing to happen (eg update) since the forum began.

Do the self-discharge test and come back tomorrow.

The solutions don’t provide a lasting or consistent fix. I reset my network settings and the improvement lasted a day or two. I did a backup and restore and again the improvement lasted a day. I closed all my open tabs in Safari and this seems to have fixed the problem most of the time, but I still get random days where the battery drains to 50% from full charge within 2-3 hours when idle.

I have an iPhone 11 Pro. Battery health was 96% before updating to 14.7.1, after the update it dropped to 86%. The phone hasn’t been jailbroken or had any modifications made to it.

I work in IT and know what I’m doing when it comes to isolating an issue. I’ve been back and forth with this problem and I still don’t have an explanation other than a fix being rushed out to fix a security flaw without proper testing. Sometimes that is fair enough and the security issue warrants a fix that causes other problems. It would be nice if Apple acknowledged this in some ways if it was the case though…..

My iPhone XR doesn't have excessive battery drain while I'm connected to WiFi, but it does have the battery issue when it's connected to only cellular. Is that the same issue everyone else is having?

If you haven't heard, iOS 14.8 has been released. Although I don't have an iPhone with the battery issue, I hope this update works for everyone.

Same here. I have the iphone 7 and after shutting down at 40% I cannot turn it back on because the battery is under 1%…
