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
Nah, I give up. Seems like every solution helps for a while, but then again phone starts to melt.
What I’ve tried so far during last 2 months:
After every fix I saw that battery becomes ok. But next day all of a sudden I feel that phone is warm, and battery dropped by 20% in an hour, all while standby. Funny enough I have cheap old redmi phone which I use for development, and it lasts a week on standby.
I’ve tried to hook up Xcode and watch activity monitor, but after I connected bug seems missing and I can’t even make my phone warm. Anyway, I don’t even know what to watch, because most of the processes don’t show up at google, or maybe it’s gpu that works hard.
My iPad has been lasting all day with normal use before this last update now it goes flat in less than two hours and even being plugged in on charge it continues to lose power.

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.
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?
Usually not much to respond to, but in this case the situation is ridiculous.
After 14.7 / 14.7.1 my iPhone SE 2020 acts like an old laptop that can only run on an adapter.
It seems there is no battery any more in my iPhone.
Charging to 100% is useless, it drains in a few hours while doing nothing.
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.

V_savings ~ Try resetting your Network Settings. Go to Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.
The above was suggested by NCheok in this same thread you've posted in. See NCheok's post here:

As the battery is six years old, I wonder whether that high 91% maximum capacity is accurate. Whilst you await possible comments from others here, consider having the battery replaced:

BMinCO ~ The long process of applying an iOS update can kill a weak, aging battery. The "peak power issue" and the "extra battery pack" making no difference attests to the weak state of your iPhone 6s's battery. ...Is it still the original one? And what's the Maximum Capacity % here?...
Settings > Battery > Battery Health
Considering the model and age, it's quite likely the battery simply needs to be replaced:

I'd take a look at this first:
http://www.apple.com/batteries/maximizing-performance/
https://support.apple.com/HT208387
https://support.apple.com/HT210512
Also cross reference the issue with different chargers(or computer), all USB ports (if using a computer), and different cords (if possible).
However, if those steps don't work, you don't want to call AppleCare, and you're worried whether it's a hardware or software issue, follow these steps:
Back up
https://support.apple.com/en-us/HT203977
Restore to factory
https://support.apple.com/en-us/HT204184
If your battery is still draining while plugged in, without any of your data or apps on the phone, then it's probably safe to say you need to get the battery checked out by Apple.
If your battery is perfect again, then you can restore your phone from the backup and see if everything is still good.
Restore from backup

I hope that helps and good luck!
If the issue still occurs after a full factory restore and the phone isn't struggling to connect to cellular/wifi, then it sounds like you've narrowed it down to the OS as the cause of the issue. The last iOS notes about an issue of the battery reading not being accurate was brought up in iOS 14.5 (https://support.apple.com/en-us/HT212247).
I didn't notice the issue until 14.6 and my phone's issue was solved after backing up my phone to my computer, although the iOS and MacOS were already up-to-date. I have noticed that my cellular strength is less, but it doesn't seem to be affecting the battery. I also wonder if the adoption of 5G is having an effect for the people that reset the network settings and still have the battery drainage issue.
Hopefully Apple will release 14.7.2 to address people still having the battery issue so we're not waiting for iOS 15 to address it.
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.

I have had the same issue on iphone 6s. I upgraded to 14.7.1 after replacing with a new battery.
2 days ago had got the battery replaced (with a genuine apple battery) at an authorized service center and after that I upgraded to ios 14.7.1
Tried everything:
Still not resolved. Battery drains out in a few hours without any activity.
Wish I had not upgraded. Also since 14.7.1 is a signed version so cannot downgrade as well. Apple please help!!
