iPhone 15 Pro, 96% battery health. It all started last week when i was still on a 18.2 beta version. I figured updating would fix it but it s even worse now. It charges quickly and drains as quickly. Randomly shuts down at i.e. 93% battery percentage. After power off, it powers up with 10%, repeats the cycle and then it just sticks at 10%. I’ll update when I know for how long it stays like this. Meanwhile do you guys have any idea how to temporarily fix it or a workaround for the issue until further update will fix it?
iOS 18.3 (22D5040d) issues with unexpected shut downs and heavy battery drain
More than anything I just want to get out of this update. My phone won’t stay on unless it’s plugged in. Same issues you’re having after the 18.2 update. my phone shows 90% battery, shuts off and cuts back on showing 10%
This is the first time I have experienced such battery drainage with my iPhone 15 plus max. Hardly touching at work, my phone is at 33-43% by 8 hrs. It charges ridiculously fast and dies ridiculously fast.
Not experienced any random shutdowns yet, but battery drainage is happening and having to use a case because of the amount of heat being generated while just reading the Daily Mail‘s news app on a iPhone is 15 Pro Max (model number MU773ZD/A)
Just a theory but if you check your analytics I’m sure you would find some type of correlation connecting your battery being used with other services in the background unbeknownst to you
Mine is the issue with the battery charge of 15 plus. Though it charges at an average speed, it reaches upto 80% and not 100% , even if the optimised charge option is unenabled . In addition there is a lot of heat generation. The service executives re installed the iOS18 full version and have asked to use the device for one wee. But no use, it is again frustrating. 28 percent charge is drained per hour. All was fine before I installed 18.2 iOS. My phone is just 8 months old and has 99percent battery life with 140 cycle count. So sad because I purchased it after saving Money for a long time.
For what it is worth, I just updated my iphone XR from IOS 17.7.2 to 18.3 and regret it, not only due to the horrid Photos app, but relevant here, Battery drain is significantly increased. Up through IOS 17.7.2, battery drain was never more than 2-4% per-day. I don't use the phone much other than to check a message or transfer a file or photo from the PC to the phone or vice-versa using Files over smb.
After update to 18.3, battery drain jumped to 13-15% per-day with the same average use. That is a 3-5 fold increase in battery drain. I've disabled the privacy invading scan my photos for landmarks, and since this phone isn't AI capable, the AI nonsense shouldn't be causing additional battery drain -- but something is -- and it is significant.
Take this as another data-point on the 18.3 battery-drain issue. There really is no reason I should see increased battery-drain on an XR, but it is significant. The only other issue that may be related to the drain is I've noticed touch-sensitivity is wildly high. For example this causes the Weather app to launch the secondary pages (like "Conditions") when simply trying to scroll up/down. Touch-pressure sensitivity was never this bad in releases up though IOS 17. Not sure if that causes additional drain, but it is worth reporting.
Let me know if you are interested in any other settings. Most everything (Siri, Dictation, Notifications, etc. are all disabled), so the phone should idle with minimal battery demand.
My phone turns off at 90 comes back up and shows %10 and immediately turns back off
Apple what have you done? I taught 18.3.1 was going to be better
Same problem in my iPhone 15 Pro, With 18.3 the battery drop suddenly and App Contacts consume about 70% its insane!
I have 15 Pro Max, and its battery health was 100% till cycle 223, after the 223rd cycle it started dropping its health and is now 95% at 264 cycles.
99% - 226 cycles - 29th January 2025 95% - 264 cycles - 24 February 2025
What is going on....
