Extreme battery drain in iPhone post update

iPhone 13 battery is horrible I charge my phone to 90 percent every night and like the past two days I’ve woke up and it had drain drastically to like 80-60 percent I’m on iPhone 13 maximum capacity 90 percent

Same with me .

the day when I updated the software to 17.5.1 .. the phone becomes dead by evening itself ..

apple should fix these bugs

I'm having the same issue! I have an iPhone 13 Pro Max, and after the update, my battery life just plummets as soon as I get up in the morning. I have to fully charge it at least by noon now, and my phone is constantly super hot! I can feel the heat coming off my phone all the time, and when I'm driving in the car, it's almost unusable because it overheats. It was never like this before the update! I literally have to take my phone out of its case and hold it in front of the air conditioner to get it down to a normal level of heat. I completely stopped putting my phone on the dash because it was so bad and it still gets overheated because it heats even more then it's plugged in and charging while using car play and the GPS.

i think the problem in your apps

do you download any hard game ?

when you finish used any programme

swep up and close open recently to ensure thats programs are not running in the background and battery consumption

I have an iPhone 14 since middle of August last year. So around 9 months.

I updated iOS to 17.5.1 today. I had 93% of battery life before an update, after an update - 91%.

2% lost after an update, not doing them anymore . . .

I don't use my phone very often FYI.

Only for music and calls, eventually some tik toks. Daily usage is for like 2-5 hours.

Me also in my 15PM in addition theres is lagging once you open the application even in vids, camera and some other application its really crazy for a thousand box mobile phone you will get less.please apple fix this.

But if we are using our phones in the exact same manner as always it is reasonable to suspect the update. I have had this happen numerous times over the years with my iPhone 13, then there will be additional update soon after which corrects the battery drain issue.

Hello, I am also facing same issue. After updating to 17.5.1 my battery doesn’t last 6hrs. Before it was lasting full day. At night almost 40-50% battery was there. But now after update it switched off today. Apple need to bring another update asap. Even battery life is reduced.

I signed up here to specifically report the battery life drainage since the update to 17.5.1. I’ve had several iPhones and this is the first time I’m concerned about the product. I’m not even done paying it off!

Not only doesn't my iPhone battery last for a day of normal use after the iOS 17.5.1 update, but the update to watchOS 10.5 that I did at the same time puts my Apple Watch in the red before end of day too.

It is very frustrating, and my daily usage of my phone or watch have not changed at all.

This issue is driving me nuts! I am convinced there is something bad in the 17.5.1 update. Since I updated to this version, none of my batteries in my 14 pro phone, apple watch and iPad are holding their charges.

Hello, I'm using iPhone 15 Basic. 128Gb.

i'm having this battery drain, unresponsive screen and heating issues (Warm to Hot device) since updating my iOS from 17.5 to 17.5.1

My battery health was fine. But the Battery life wasn't, and the heating issues is very annoying.

is there any chance to fix this? Or iPhone 15 basic just sucked at it?

I’ve got the pattern: Apple does something without notifying me on my iPhone XS, then for a short period of time it returns after last update of minor version to normal battery usage ONLY to keep user patient and make user to upgrade to the next major version. Every time after such upgrade (don’t tell me to reboot and update apps, it’s always done) the battery is draining again. So, the question is only: what exactly Apple is doing silently on iphones?

standby battery timing is worse on my iPhone 15 Pro Max after updating to 17.5.1. every night i charge my iphone to 100% and turn off wifi aswell. the battery drop from 100% to 90% daily without even touching my iphone. it

Same issue - noticeably excessive battery drain after 17.5.1 update.

Same issue across 3 devices - iPad Pro / iPhone12 / iPhone SE 3rd Gen.

Devices been used in same manner since new, no changes made to settings and then hey presto after update, having to charge more frequently and battery draining even when devices sat not being used.
