iPhone 15 Pro Battery Drain Issue

I have bought iPhone 15 pro recently. The expectation is battery should be efficient, but is performing poor than iPhone 11. Especially Findmy app is used all night. The battery went down from 55% to 32%. Please help me to fix this?

I’m having the same issue and it’s ridiculous. I remember when I got the iPhone 13 the day it came out, my battery lasted 2 whole days before I had to charge it. Only took about 30 minutes to fully charge. I traded it in with 84% battery capacity, but it was still working great. Now with the iPhone 15 Pro, the battery life doesn’t last half a day and it takes about an hour to charge.

also having this same problem, been using the phone for two days, have gone through today and disabled always on screen, disabled background refresh etc. which I’m hoping will help. I’ve been getting battery life comparable to my iPhone 12 with 65% battery health, I just want my phone to last the day, is there any word about Apple updating their software or is this a hardware issue, will a new iPhone 14 be better for battery life? I feel like I’ve never had this problem with a brand new iPhone before.

I have the same problem with my iPhone 15 Pro. Must say I am very disappointed. I paid a lot for a new phone and the battery is seriously barely better than my iPhone 11 Pro with a battery condition of 79%. I'm going back to the store tomorrow to address this issue and find a reasonable solution. I'm not going to spend 1300 euros on a phone with a bad battery.


The previous times I bought a new iPhone I could easily use it for 1.5 to 2 days without charging. It's ridiculous that this is no longer possible while Apple promises 26 hours of battery life when watching videos.

It looks like it's not constant : the battery drops in waves, and not every time. Maybe it's a problem of battery "too new" comboned by the new phone doing some sync / update of data and/or app updates / downloads ?


I asked my wife to let it discharge until shutdown 3 or 4 times to see if it clears the issue before goint to an Apple Store for an exchange.


It looks like it can loose 15% in 10 minutes but then stay in the same % for hours. very irregular.


Putting it in battery save and cutting all features like always on, bt, wifi, gps = changes nothing to the issue.


The battery health panel says 100% peak performance but on the graph I can see the staircase like moments where it drops. Today there was two of those drops.


But it looks like it will be able to handle a full day or more. ( 15 pro max 17.0.2 )


So there is some nuance to this problem.


I don't see any staircase in the 14 pro max battery health. With light use my 14 pro max loses 25% a day. (it's an idle phone waiting for sms)

I don’t think the first few charge cycles of an Iphone battery see any change in capacity whatsoever. As for restoring new phone from backup and synching settings, pics etc, unless you are talking massive volunes if data a day will see that all done. Location services were my biggest drain. With Safari location setting switched off as soon as I opened any web page the location setting status icon appeared (what gives? Bugs perhaps?) Turning off Location services totally has nade a difference but using maos then requires swithing loc services back on and to precent rinsing battery, turning loc setting back off, hassle! I think exchanging phone a waste of time, clearly Apple have either some Ios bugs to zap or more ominously, the 15 pro is destined to provide pathetic battery life to all who have one. Rumour has it the 16 pro and max will be bigger. If true thatcwill be to accommodate appropriately sized battery perhaps?
