iOS 17.2.1 Battery Drain

I’m experiencing the same issue and it’s frustrating. It’s another move to make us upgrade to the latest iPhone 15–this is getting old Apple. You did this with versions 4-6. I’m happy with my 13 and don’t want to upgrade because your latest software is made to optimize your latest iPhone.

I wish there was a way to rollback IOS versions.

I have an iPhone 15 Pro since 1,5 months and just can tell you that the battery drain is very high with iOS 17.2.1, there‘s also an overheating sometimes which I don’t understand. As Apple said, the 15 Pro & Pro Max are „Gaming iPhones“ - I have no idea how that should work as I‘m doing very normal tasks (no Gaming!) and my battery gets empty very fast.

It took my phone out completely. Finally got it restored and now battery drain. Usually in my morning routine I use 5-8% of battery life, I am currently down 27% and haven’t even finished morning stuff.

I'm having the same issue. I applied the update last night and today I woke up took my phone off the charger checked my messages then googled what was new with the update and 20 min later from the time I unplugged my phone for the charger I'm down to 14% 🤬😤

No new apps or change in usage. Hopefully this is corrected for us all immediately

To add, what I noticed is that when i am out and on Cellular, the screen idle time is insanely high. That could probably be the cause, anyone else having very high screen idle numbers?

I have AOD and Standy OFF

iPhone 14Pro a year old, 3 1/2 hours after full charge battery is down to 50% only using iMessage and a taking few photos. Tried deleted vpn profile and restarting as suggested. Makes no difference. We need a fix please Apple support!

I have the exact problem with my SE2020. Battery used to last 2 days but now after 17.2.1 without using it and leaving it on standby it drains right down and into the red. My battery health is 100% as the phone is not very old. When Apple sort this, they better, I will not update my iOS anymore.

I have four Apple devices and my wife’s iPhone SE 2020 is fine with no issues, that is because she hasn’t updated from 16.4.1. The Wife is always right as they say.

Please sort it out soon Apple for your loyal customers.

I’ve noticed the last few days or so that my battery is draining more quickly than before. By the end of the day, I’m down to approximately 30% or so. I’ve never been below 60 percent on a normal day of usage but now battery is draining more quickly. Have iPhone 13 Pro Max, iOS 17.2.1

Well I am totally agree with you. I am using iPhone 15 pro max & before updating to 17.2.1 my battery life was so good & now its getting horrible day by day i don't know what’s wrong with the latest update & why Apple don’t listen to users to give bug free experience. Hope to see a quick fix next week

Same here on iPhone 12. Updated from the most recent ios16 and there’s a very noticeable drain on the battery.

I’m just doing the usual basic stuff: email, reading news etc. In the time I logged into this site and typed this reply, the battery has dropped 2%!

SAME HERE, I have the 15 pro and been averaging about an hour idle time even though I never used AOD or standby mode like ever, also only happens on cellular… Only been getting 5-6hrs before needing to charge it again also, before it was usually like 6.5-7 before needing to recharge, its sad really as I bought this phone to be able to last me quite a while which it did a while ago and still at 100% health

After 17.2.1 my battery drain is very fast I used charge my iPhone 13 every other day I don’t use my iPhone a lot I have an iPad this morning iPhone 13 Pro Max was 80% and now is 36 I didn’t even use it no phone calls or nothing and numbers are gone down constantly without any use now I’m typing and lost 3%

Same here.

iPhone 15 Pro Max (bought on pre save) just updated to 17.2.1 and suddenly battery is horrible.

I have same usage of the phone that before and now I end the day by 20% (before I had around 60% at the end of the day).

12 Pro Max - same problem 😭

When I facetime it used to charge normally and now (updated to 17.2.1 last night) it doesn't even keep the pace and the battery is draining...even with very low briggtness! 😡😡😡

17.2.1 Battery Drain (12 Promax) - Normally I will get through the day using about 50% of the Battery.

Today not using the phone much at all I’ve gone from 100% to totally flat before getting home.

Never thought I’d say this but thinking about ditching Apple.

Not Happy at all ☹️
