iPhone battery draining after iOS 18 Update

I’m currently on IOS 18.0.1 & my battery drains pretty quick. hopefully they fix the battery drainage issue on the feature iOS update. ANY SOLUTIONS TO THIS ?

I updated to iOS -8 yesterday and my phone battery is draining twice as fast as normal. Is there some new setting that need to disable ?

same here

Any online form for submitting this issue to a develop team?

The issue STARTED with 18.0.1 for

My iphone 15 battery is draining drastically. 2% battery health dropped in two consecutive days. Very poor optimization done by the devs

that happened to me either

this is happening to me also. I’m having percentage anxiety.

Battery drains to fast constantly hot as well

Been on iOS 18 since day 1 of launch on my iPhone 12 Pro and can confirm that the battery is draining faster than when I was on the latest version of iOS 17. I’d say it’s as bad as the earlier versions of iOS 17… hope they resolve this in subsequent updates

Battery drain can be prevented by resetting the settings of the iPhone (Settings - General - Transfer or Reset iPhone - Reset - Reset all settings). It will not delete any data.

It helped in my case - iPhone 14 plus post updating to ios 18 and battery drain is back to normal scenario.

This issue is not unique to the iOS 18 update.

I’ve noticed that battery life gets impacted every single time have updated the iOS on any of my iPhones I have had since iPhone 1. This is especially true if the update coincides with the launch of a new iPhone model. Even when I have paid to have the battery replaced, it doesn’t seem to help the issue

Actually, such battery drain is a norm after each iOS upGrade and some iOS upDate. It will recover eventually.

However each upGrade will tax the battery a lot. My older iphone 11’s battery health always degraded with each upGrade. For the last upGrade from iOS 16 to iOS 17, I put the phone on a towel with an ice pack below during the upGrading process 🤣.

I am choosing not to upGrade my old iphone 11 and iphone 15 plus this time.

I am using iPhone 15 pro max and after I updated it to iOS 18, my device battery is draining drastically, previously I have to charge it once a day but now with my same daily routine I have to charge atleast twice a day.

It’s not about getting one to up-grade. Just upgraded to iPhone 16 running iOS 18. My old phone was an iPhone 11 running iOS 17.6. Never realized how good I had it battery wise. Maybe I got lucky, cause the old phone would hold its charge for 2 days before needing a recharge. Though after 5 years i was having to recharge it every night.

So, I decided to up grade. I needed 5G anyway. This new phone sucks power, about 6% per every hour of active use. Either I have a defective battery or Apple needs an update to iOS 18.
