How to Fix iPhone 15 Pro Battery Drain After iOS 18?

Since upgrading to iOS 18.1 RC on my iPhone 15 Pro Max, my battery life has significantly deteriorated. Despite implementing various measures, including minimizing background app refreshes, reducing the number of location services, and disabling push email etc, the battery continues to drain at an accelerated rate. During idle periods at night, the battery consumption has nearly reached 10%, compared to a mere 2-3% with iOS 17.

I never had the weather widget on my i15 Pro since day one with iOS17, but yet still facing this Battery Draining issue after updating to iOS18.

Home & Lock Screen is the culprit.

I have only used my phone for about 2 hours this morning playing music via Bluetooth and making a few phone calls totaling about 1 hour and have lost 30%. I hope there is an update soon to fix this. Battery health is still 99% on my year old phone. 175 charge cycles.

I have the same issue too, i’ve been trying to get a solution for this problem for the past couple of days, but nothing changes. My phone is around 1 month old now (Iphone 15 Pro) and for me, for some reason “Home & lock screen” is draining my battery super fast. I don’t even have “display always on” in the settings. Before iOS 18 it was working totally fine, could go a day without charging, now I have to charge it twice in a day. I hope they fix this, because for this amount of money, this phone shouldn’t drain too much.

Same here. I have an iPhone 15 pro max. Same issue. Before iOS 18 my battery was stellar. Now I need to charge it like 6pm when I never had that problem on iOS 17.

this needs an urgent fix. A fast fix.

+ 1, it is the exact same problem that I am facing. I use a 15 Pro MAX and battery has been draining since the ios18 upgrade. Surprisingly the Home & Lock Screen is taking away 10%+ of the battery usage. What is the fix for this?

Same. iPhone 15, and have noticed a significant change in my daily battery drain since updating. Don’t even enjoy most of the iOS 18 features, and nothing has changed in my usage. But I’m 50% by middle of my day when I used to never get below 75% by now.

It’s awful. I feel like Apple does this intentionally every year to get people to buy new phones. iPhone 15 Pro Max

Apple has already stated many years ago that they had never, nor would ever "do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades.

Same exact thing here. iPhone 15 ProMax and Ios 18 is completely draining the battery in record time! I've watched a bunch of videos on YouTube and changed all the suggested settings and nothing. I shouldn't have to do that anyway, things were just fine on iOS 17. Before the update if I burned through more than 50% battery during the day, that was a lot. No idea what to do here, is completely frustrating and now I'm what? Gonna have to buy a back up battery to walk around with all day??

I have the standard 15 and have only had it for a few months. I will be on my phone for 5 minutes and literally lose 5% or more. It's insane because I've never had an issue with a battery like this before. They need to fix this battery drain with an update fast, because it's dropping beyond normal speed

I’ve tried nearly everything. Less than 10 hours battery life when I could get much more. iPhone 15 Pro base model. Please send help Apple. My Ultra 2 watch gets multiple days now, it’s like the life went from my phone to my watch 😅

I have the same issue, along with using pandora I noticed on riding my Harley 97% before leaving and opening pandora riding almost 3 hours round trip and playing pandora battery was at 7% upon arrival at home.

Same issue on my iPhone 14 Pro Max.

great battery life for a long time, but iOS 18 occupies 30% extra battery life per day.

This is on top of already doing the guide stuff and turning off all the cool options like always on display, tracking, blah blah.

I've updated my iPhone 15 Pro to iOS18.0.1 this morning, but it does not rectify the Battery Life Draining Fast issue. Home & Lock Screen still consume a lot of battery compare to my iPhone 13 Pro on iOS 17.7.

Apple, please look into this Battery Life Draining issue seriously.

Same here. Battery on 15 pro max literally cut in half. I went to B 18.1 to fix the keyboard lag issue but battery is still awful. Charging times are MUCH slower now on MagSafe chargers too which is ridiculous, so I can’t even properly charge it on my OffRoam car chargers during the day because it’ll only charge like a percent every 5 minutes. Either way, my battery has been awful and continues to be awful on the 15 PM. capacity down to 92% too after a year (got it on release in 2023). I honestly can’t believe it’s this bad. I don’t think I’ve ever had an iPhone whose capacity dropped so much and battery life was this bad ever.
