iphone 15 pro battery drain IOS17.1

Issue is Apple software update.

I saw this issue battery drain with no all refresh with 15pro out the box.

then update came out. Issue gone.

then fine for many weeks.

then recent (week or so) 17.1.2 patches phone and battery issue back again.

drains from full to 20% over night with barely any use.

im going to find out how to roll back patch to 17.1.1

Huh? Your battery's backside is sitting on iOS 17.1.2? Or your battery is made of pirate treasure?

Perhaps you should update to iOS 17.2.

I bought 15 pro recently and the battery is a huge problem. It drains even faster than my old iphone 11. Any suggestions how do I fix or if this is a common issue through out 15 pro community?

My iPhone 15 Pro has fantastic battery life. You might find that, for the first couple of days, it's draining more quickly than you might expect because it's doing a lot of background tasks related to the initial set up.

Just perform reset all settings and that’s done trust me

just reset all settings it deletes nothing from the phone

No it didn’t. Had my new iPhone 15 pro max for less than a month. Battery worked normal all till Sunday. Then Monday it was like I had the phone for years 7% battery drained every 10 min even if I wasn’t on my phone with all recommended settings turned off

100% an issue. I did not read all these replies but the few I skimmed that are suggesting storage capacity and whatnot would be completely unrelated.

I use my iPhone to shoot content and stream. Shooting video I get about a third of the battery time compared to my iPhone 14 Pro that was just about a year old. Same video recording settings. Streaming on TikTok about half the battery time.

I am sure this will be one of those issues they resolve with an iOS software update in the near feature, I doubt it's the hardware itself.

My day 1 released Pro 15 was battery whacked then Apple released an update not long after lunch and magically the battery was fine. 17.1.1 was operating perfectly fine no battery drain. It lasted amazingly long. Much better than my previous 13 pro. 17.1.2 patch and the battery is back to problems again. I have all background everything off. I am in low power mode. Last night it drained in low power mode from 70% to 30% off charge This is an apple issue. It is not an issue they need to fix it. 17.1.1 was perfectly fine. I can’t believe the size of Apple does these things. Amazing amazing. Samsung? Who am I kidding I can’t leave Apple.

I wrote it wrong i mean reset all settings

not factory reset

You turn your phone off and the battery was going from 48 to 38 %

phone was completely turned off ?

You have to uncheck some things on location services

Same problem here. At first I thought it was something from old iPhone (bloat) transferred to this one via backup restore. So I decided to erase and reinstall everything manually, I didn’t even restored settings or anything else.

Now I think is something else. Battery drainage is based on user account and not by apps, settings or cellular signal…. You simply deserve so much battery performance.

chaim195,have you checked your ph storage capacity to make sure you have enough head room. If you have added a large amount of new apps and have a huge supply of undeleted email(with pictures) messages with same undeleted ph recents and voice mail which all use a lot of power when all added together but if nothing has changed then it’s a puzzle.

Although that advice is good, your reason is not quite right. Large amounts of data don't have a significant effect on battery usage once they are already stored on the phone. Having insufficient free storage space will affect how smoothly the phone works and can potentially lead to data loss.

Cellular signal (or lack thereof) has a huge effect on battery drain. Certain apps can also use up battery quickly.

I am very concerned. I bought the iPhone 15 pro today. I downloaded all my stuff from my old phone. The battery went down of 30%. The phone is so warm since… It’s scary. I feel the phone is about to explode. I regret my choice. I’ve always been an iPhone owner. Maybe this one is the last one !

Wtf is wrong with this phone the battery is draining like mad have switched off everything nothing is running the background bg refresh is off always display is off still 10 percent battery drained in one hour while the phone is not being used 😩😩

You will nothing lose

Just have to type in the Wi-Fi password after that

Resetting to factory settings deletes EVERYTHING on the phone. Unless there is a back up to be reloaded, yes, you WILL lose everything.
