I wanna to report about my experience that :-
IOS Version 15.4 = Battery Drain fast while you use the Phone
IOS Version 15.4.1 = Battery Drain fast while the Phone in mode Stand by (Not use)
Today, I already upgrade my iphone 13 pro max from Version 15.4 to Version 15.4.1 in Time :10.00 am, battery = 71 %
but Time : 12.00 noon now battery remaining about 61 %, , I only click app only a few 2-3 minutes,
iPhone 13 Pro Max, iOS 15
Here are some articles that may help.
This was from last night. Kept my phone plugged in till I went to sleep. Closed all apps. Cell service off, bluetooth off, just wireless. At 03:00 woke up, used app to turn off heat - closed the app. Battery drained at a rapid pace all night and I woke up to a 1% battery.
My iPhone 6s battery drains from 100% to zero overnight. During the day it does the same thing. My phone is set up for battery preservation (no automatic updates, no background refresh, etc). This is new with the new updates. Prior to this, my battery life was normal. My phone has been made unreliable by this update. To use it without keeping it plugged in all day I will have to buy an external battery and keep it hooked up to that.
Apple needs to address this and re-issue a new update.
I'm using iphone 13, and my 15.4.1 drains faster than ios15.4. I updated to 15.4.1 a few days ago.
I have wifi, bluetooth turned off, and disabled app background refresh. I also has power saving mode on. From 00:00-7:00 nothing was using battery. Who knows what happened during my dreaming?!
My battery health is "Maximum Capacity 81%". Two weeks ago when this problem began - with the new software update - the battery health was 87%. This new software is killing my battery. I cannot use my phone for any normal length of time without having it plugged in to an outlet or to a spare/portable battery.
Yes. My iPhone XS Max was absolutely fine. Never, ever seen the battery go into the red. It could easily go into the second day with moderate use. Now I can barely make it to 14:00 when I need to plug in charger. Really not happy
I'm sure Apple got what it wanted. My 6S was all I needed, but the battery killer iOS made it unusable. The battery was fine, whatever the new iOS was doing to it killed it. I "tapped out" and had to buy a new phone. With the exact same phone settings, the new phone just sips from the battery.
If Battery drain so faster than last Version (15.4)
Who wanna pair the iphone with Airpod or Apple Watch??
iphone 7plus battery is draining faster after the 15.4.1 update than before
