Battery Drain on iOS 26 and iOS 26.0.1.

Me too, with my iPhone 15 plus, which is totally brand new, i bought 3 weeks ago

after updating to ios26 and then 26.0.1, I noticed a total shift from battery life, drastic downfall !!!!

burning battery without doing anything!

I urge you to come with a rapid solution to this massive, frustrating problem!

Yea True.. Battery life was at 85% before the update. Two days after the update, it was shown as 83%.

Now that I look at it today, it's 82% and the battery health is decreasing in an increasingly short period of time.

Very Disappointed Apple!

I surely hope so! My little iPhone 13 mini is draining like there's a hole in it (85% battery health, low power mode does not seem to help, I only have 3 widgets on the lock screen - Clock/Weather/Calendar, and removing them did not seem to make a difference). I don't want a bigger phone. I like the smaller phone. It fits in my pocket. My desktop Apple mouse is also draining rapidly, and I have to change the AA batteries much more frequently. I try to remember to turn off the mouse when I am not using the desktop (mini m4), but I often forget to turn it off. It is an older Magic Mouse. There is much to like about iOS 26.01 (and Tahoe 26.01), but the battery drain is a real and ongoing problem.

I previously posted my iPhone 13 went from 47% to 10% instantly (and even 100% to 10% instantly) and kept restarting. It got to the point I had to keep my phone constantly on the charger, until I saw the screen was swelling open. I didn’t remember it doing that at all before the new iOS, but clearly it had become a hardware issue now. Fortunately I was able to get a new iPhone 17 from AT&T the next day (and I was due a free upgrade).

iOS 26 is so far working great on a NEW IPHONE 17, and it is very smooth. So far the battery is doing well on the new phone (but I don’t have anything to compare it to). With light use I charge it every other day, and moderate use every day.

So it looks like this iOS works alright for NEW phones, but was either not designed with old phones in mind, or (hopefully not) intended to tank old phones.

You have to appreciate Apple’s gentle way of saying that you should probably upgrade your iPhone hardware to 17 series as well.

Interestingly users of 16 series were not spared as we have seen number of reports from customers who purchased even iPhone 16 Pro Max models and are affected after upgrade to iOS 26.

My phone battery life is terrible after iOS 26 update. 3 weeks now and battery dies twice a day. Prior to update it would last over a day. Already contacted apple and they said nothing is wrong with my phone after diagnostic. Terrible

On iOS 26. My battery used at night when I was sleeping was around ~5% when I killed all the background apps. Now the usage is around 15-20% in the same period with all apps killed. This is definitely not normal

sry for msg

my phone battery drain quick after update ios 26.

before update. ios 26.

in ios 18. ill use my phone 1 day. now i cant use my iphone after update ios 26. because. cant use phone battery drain very quickly. plz gave the solution for that problem. thank you.

Sorry you are dealing with this. iOS 26 absolutely destroyed my cell phone and Apple Watch battery life.

both products just over a year old not even paid off and the battery is horrendous on both

i know I know it’s a ME problem. With 2,000$ worth of Apple products I should have to turn off every single feature just to make it to through the day.

after 13 years with Apple this experience has really shown me that it’s time to switch

once these devices are paid off it’s a Samsung phone and a garmin watch hands down

apple is not what it used to be

I've done all that. BTW Apple should correct the page about force restart. As described it *does not work* on my iPhone. When I press/release volume up and then volume down, and then press and hold the right side button it just activates Siri. In order to do force restart I need to simulataneously press and hold the volume up and the right side button.

Hello~ I don’t have the ability here to censor anything. I am a forum member just like you are. If you are having your posts edited then likely there’s a good reason for it. I do however have a tip for you…discussion of moderation isn’t allowed here. This is Apple’s site so their rules apply. How do you know that you didn’t offend someone?

I’m having the same issue, my iPhone 16 pro max had 100 percent battery capacity hold, and now it dropped to 95 since the update, and I literally have to charge my phone every day now instead of every other day. It was 96 percent capacity last week and it’s 95 now. This sucks because this phone battery is getting bad faster than my iPhone 11. We should at least get battery replacements for the price we pay.

I really don’t get it. I never ever charge any of my iphones overnight. Never. I’m still keeping my 13 Pro Max, battery health is 94% (original), I usually plug it when it reaches 30%, then charge up to 80 / 85%, and, every other month, I let it charge till 100%.

Never charged it overnight - and, since day 1, when I go to bed around 1 AM, let’s say the battery is 72%, when I wake up around 5:30AM it is still at 72%. Never missed a beat. And now, aproaching day 1460 (4 years), it’s still behaves the same way.

Oh, BTW, same with my Macs.-L)

Won’t talk about MBA M3 (16GB and 1TB) since it’s new (less than a year).

But I still cherish a dear beloved MBP mid 2012 - 87% battery health (O-R-I-G-I-N-A-L), which is the last model with a DVD drive and upgradable - now with 16GB and 1TB as well.

Maybe I’m lucky, and certainly I’m not an expert in tech as most of you guys, but apparently I’m doing something the right way (hope it holds…)

And, finally, didn’t have the “courage” yet to update my devices to neither IOS26, nor MacOs26, nor iPadOS 26.

Waiting a bit more to get things more stable.

Just wanted to share some thoughts with y’all.

Cheers.

The same problem is on my 15pro , ever since the update my phone does within 4hours whether I use it or not. If I leave it overnight with 80% battery I wake up in the morning to a battery dead phone. I have to charge my phone 4-5 times a day. Currently I've just switched it off and switched to an Android which I last charged 100% over 24hrs ago still it is on 17%. Can anybody help me with this issue. I do not use it at all . Just for calls I have deleted meta apps due to it not being optimised for iOS 26 ... Yet I am facing ridiculous battery drain. Home and lock screen is the battery drainer

It has nothing to do with a fresh iOS 26 installation, the issue still remains after more than a month. Feels like my almost new iPhone 16 Pro Max has changed into a very old iPhone although max battery is still at 100%
