Battery Drain on iOS 26 and iOS 26.0.1.

What does Lock Screen show for usage?

IOS 26 is a really disappointing experience. I am facing heat and battery drain issues. The biggest problem is there is no official way to go back to IOS 18 which was giving a good battery backup and less heat.

The UI liquid glass, I don't like it at all, its so bad.

I don't know why apple is release new versions of IOS without doing proper testing.

I hope apple will fix this issue soon.

yes, even I am facing the exact same issue. I updates to iOS 26 2 days ago and my phone has been heating up while charging and the battery is draining almost 3 times as fast. I would usually be down to 50 percent charge from 90 at the end of my work day with extensive usage but now in down to 50 percent from 100 at 12.pm with very minimal use and low power mode on. This is a new iPhone 16 purchased is July of this year. Apple team please help

Similar experience on my iPhone15 Pro. It's not new, but I noticed an extreme drop after updating to 26.01.

When I updated to iOS26, on the same day, besides the horrible UX/UI of Liquid Glass and several bugs (that you would totally expect from a small indie company such as Apple) I didn't noticed any major effect to battery.

26.01 however is destroying my battery. What a nightmare of an update.

this also happens to me.. i have background app refresh, low power mode, and clean energy mode all enabled while i have a newer iphone and my battery life is 93%. before downloading the update, after a full day, i would have around 45% but with the update, not even 2 hours later while being inactive has me on 29%. PLEASE FIX THIS!!

With iOS 18, the battery on my regular iPhone 16 lasted until about 11 PM, reaching 20% by then. With iOS 26, doing exactly the same things, I now reach 20% battery around 4 PM. So yes, iOS 26 causes severe battery drain. The user interface, even though it hasn’t changed that much, seems to require much more power. Please optimize it!

While my iPhone 15 Pro is not new, I am experiencing severe battery drain after updating to iOS 26. I did the update the day it came out, so almost 3 weeks ago. Prior to the update I could go all day from 6:30 am to 10:30 pm and still have 30% to 40% battery power left. Put on the charger, connected to WiFi overnight each time. After the update I am down to 15% of less by 5:00 pm. No new apps, same settings as before. When using my go to news app that I use every day, I can literally watch the battery percentage drop while I am reading the news. 15 minutes on the app and I will lose 10% to 15%. Yes, I have updated that app, no change. After this situation began I researched online some possible solutions. Here is what I have done so far:

-Turned down the Liquid Glass feature (useless feature IMO) to the minimum available

-Turned off the Always On Home Screen feature I was using since purchasing the phone

-Turned on Adaptive Power

-Automatic Screen Brightness has always been on

-Cycled my phone off and on

-Updated apps

Nothing has changed…nothing. My wife and I own a MacBook Pro, iPad Pro, two iPhones, iMac, Apple Watch Ultra, Apple Watch 10, Apple TV, HomePod, HomePod Mini. I feel like we are pretty committed Apple customers. This has to be the worst experience we have had in all the years of being immersed in the Apple universe. Please…someone, do something to fix this very real issue.

Called Apple Support, ultimately got on the phone with a supervisor and while he was doing a screen share with my phone, disconnected the call and did not call back. Great service. I guess I need to inconvenience myself even more and make a Genius Bar appointment. Or maybe this is just Apple’s way to force me to spend $1000+ to purchase a new iPhone 17 so I can use my phone all day like I used to be able to do prior to the update.

I have the same issue on my Iphone 13 Pro Max. Not the newest battery, but no problem lasting a day and a half with quite a lot of use. Now it is all drained in 6 hours. Hope this can be corrected, Apple…. Quite dissatisfied at the moment.

The 26 & 26.01 updates are DRAINING MY BATTERY! I text all day for my work and from 7:30am-12pm my battery is down below 40% I can barely make it to 3:30pm without being under 15%. This is total BS and needs to be fixed ASAP! I don’t appreciate having to buy more power cords and blocks to now try and charge on my 30 min lunch break! Apple ****** me off. Let us decide what features we want. FIX THE BATTERY!

I did an update this week and I am having the exact same problem. I have an iPhone 15 that is one year old.

My battery health says it’s fine however my battery is draining after a few hours and I am not using it any differently than usual. Today I had to charge it three times and on a normal day I still have over 45% at the end of the day.

I don’t know dude, maybe you don’t have problems while others do. It’s not hard to understand. Why does a $800+ phone drain so much battery only AFTER a particular big update? It worked perfect iOS 18. But I’m sure it’s all 1 big coincidence that a plethora of users are complaining at once

the truth is ios 26 has battery drain issue ,some are saying use power save mode ,,why we use in power saver mode thats ios pblm not our pblm , i am facing huge battery drain in 26 ios then i update to 26.0.1 but still same issue ,, in have updated all apps and its been 20 days still facing battery drain issue ,, and there is no option to change to previous 18.5 ios ,, 70% battery when is restart it gets 64% ,, phone iphone 15 plus ,,,

I agree and have the same with a year old 16 pro. Battery is 100% health all apps closed and battery drains within 8 hours. My wife has the same phone and hers is worse son and daughter have 15 and 13 and theirs are worse. All on 26.01. Was on the beta and that seemed to have sorted it. Come on Apple not acceptable.
