Battery Drain on iOS 26 and iOS 26.0.1.

I recently got an ipad air few weeks ago. With ios 18 as default so when I updated to ios 26 and now 26.1 my battery performance drastically decreasd. I use 80 percent limit, turned off background activity, tried force restart and factory reset but nothing brings back the old ios 18 battery performance, even if I charge it to full I only get 4 hours of battery. Should I try doing a clean install? Please help me.

I too have experienced this issue & agree it’s a big problem. I’ve also had continued sound issues with my apps, requiring constant re-setting of my phone. I thought the update would fix both issues but I was wrong.

You may not be aware that Apple always rounds down the tenths of a percent in the battery readings.

So, when you say that your battery was at 99%......it may have actually been at 99.1%.

And, when you say that your battery was at 98%.....it may have actually been at 98.9%.

So, when it looked like the battery declined from 99% to 98% in 4 days, a decline of 1%.....what may have actually happened was the battery declined from 99.1% to 98.9%.......a drop of only .2%.

You don't need to worry about the battery. Just remember to replace the battery when it is down to 80%

How is it Apple’s fault third party apps aren’t optimized? Do you want apps banned from the App Store until they’re updated? Maybe you think iPhones should be made with larger batteries and weigh twice as much and be twice as thick (not to mention even more expensive)? In my opinion it’s unrealistic expectations people have because they spent a lot of money on a new device and expect perfection. It just doesn’t happen in a modern world.

EXACTY. I see nothing but 2 Apple engineers on their alt accounts blaming everyone else. The bottom line is this: my phone with a brand new, apple installed battery, is having issues 2 weeks after completing iOS 26 update. No issues before, and I’ve given plenty of indexing time, so don’t give me that nonsense.

how about these people grow a brain with some nuance and realize that maybe the apple gods didn’t optimize this OS for their older phones, just a thought, but they’ll probably reply with more excuses.

I see someone with a vivid imagination. I use my real name so you can easily search who I am and know the veracity of my answers. Unlike vimal256 that could easily be a AI bot or just a troll with nothing better to do.

Mine it's iPhone pro 16 I was just at apple my battery is working on full capacity and right after the update my battery goes down in few hours. Before that I it won't be wasted below 60% even in good use . And that's why I came to check what the new update did that the battery is draining just like after every big update and something is switched on to do so hidden till ppl figure it out .

Thank you Andrea-Filice for your patience and persistence in this battle. I experience similar symptoms and have tried many of the “fixes” suggested by Apple with little or no success. I havent the time or patience to spend on it but will strive to endure until Apple truly corrects the problem, or I’ll explore Samsung options. Thanks and best of luck.

Crazy battery drain now nothing changed in my use yet now I have to charge a couple of times a day and see my second app down 9% usage for something that was open 30 minutes (the app connects to my solar system) that’s just insane

Good morning battery drain team! Latest status. Removed my phone from the charger after overnight charging at 6:00am. Battery showing 100%. Laid the phone down on the kitchen counter. 2 hours later with no use at all, battery was down to 94%. But, according to John, it must be user error or incompetence, lol.

Not only battery drain issue i am facing in my iphone 14. also it has bugs in wallpaper settings.while i am trying to set up my wallpaper from lock screen screen gets laggy. Need to solve these issues asap

This is called obsoletion.

the iOS is optimize for the phone they want you to buy not the phone you have.

No matter how many things they’ll give you the option to turn off, the drainage will still be credited to all the new features causing the drain regardless if you turn off the features and never use them.

this message will self destruct in as many moments it takes someone else to censor it.

I am also having the same issue after updating to the new IOS 26.0.1 I have an iPhone 14 pro.

I use to be able to go 12 hours now I can't even get 6 hours out of my device with out charging it.

Apple needs to fix this issue ASAP

Yes I have the Same issue with my iPhone 16 Pro.

use to go all day with out needing a charge now I have to keep it on the charger most of the day. I should just go back to a land line if I need to be tied to a wall outlet all day.
