Battery drain in iOS 14.7.1

Hi,


Battery drain is happening after updated to iOS 14.7, the percent is jumping from 77% to 71% without almost any use, I am using the iPhone 11 Pro normal and my battery health is still on 100%.


Is anyone experiencing this too?


iPhone 11 Pro, iOS 14

After the last iOS update 14.7.1 my phone’s (iPhone 11) battery seems to be decreasing at twice the speed. Doesn’t even last 12 hours. It was performing fine till a day before the update.


Anyone else facing the same problem?

Yes I have this too, only since upgrading to 14.7.1 from 14.7 earlier this week.


The battery drained 50% this morning from a full charge in 3 hours. I didn’t touch the phone.


The main culprit is the browser, according to the data.


iPhone 11 Pro. Battery health is 88% but this drain problem only started happening after the upgrade.

I also experienced battery drain on my iPhone 11 Pro (HK edition with 2 physical SIMs).


What I realize was happening after updating to 14.7.1 is my "primary" line will always appear to have no reception when I wake the phone, it takes a few second for reception to fully restore.


While my "secondary" line has full reception as usual.


I figured, my "primary" line must be constantly trying to establish reception, I was draining the battery at approximately 10% every hour.


Decided to "Reset Network" settings to see if it will fix my issue, I am glad to report that my battery drain was solved with this action.


My "primary" line and "secondary" line are both showing full reception as usual. It's been 5 hours since full charge, and my battery life has not dropped even 1% through my usual usage practices.

I checked the battery usage and a message told me I'd been using the device more than usual since the update: WRONG. I shut it off completely after charging at 10 p.m., turned it on this morning to watch a movie--as usual--and the battery level had plummeted. Usually, the device stays on after I pull the plug on charging and it works on tasks while I sleep. Turning it on must have taxed the battery, eh? Device is 16 months young.

My device (Face ID sensors) is over heating after updating iOS to 14.7 (and then 14.7.1). I disabled Face ID and then try to set it up, but now it's unavailable and shows a warning message that iPhone needs to cool down before using it. Battery is draining drastically without any usage. I'm not sure if this is a hardware or software issue. Any solution?

I have this too, From the upgrade of 14.6. But yesterday I upgraded 14.7.1 still the same problem have.


The battery drained very quickly like if I charged 100% and even though I have not touched the phone, check it within an hour it shows 85% or 80%

Background running also I checked. Nothing there. And I have done a network reset also.


Model: iPhone XS Max. Battery health is 100% but this drain problem only started happening after the upgrade of 14.6 till now(14.7.1)
