Battery Drain on iOS 26 and iOS 26.0.1.

You’re not addressing Apple here. This is a user forum.

I suggest a visit to the Samsung or Google community forums. They have virtually the same complaints about their phones on Android.

Either way good luck!

I am also having the same issue with IPhone 15! My battery is draining completely in a half days use since the IOS 26 update! I have the power save made on, background app refresh is off, and I deleted every unused app from my phone already. There are no apps that need updates either.

4 min of YouTube draining 10% is for sure normal 🤣. I used to watch 45 min for 10% with iOS 18. I used my iPad 20 min today and it’s down 21%, if that not an issue I don’t know what is. Even if Apple fixes it in 1-2-3 months, the battery is also ruined by many more cycles than necessary. I think it should be looked into urgently and Apple should really focus hard on avoiding this on each update. It’s happens almost every time a new OS is released.

I'm almost a month after an update. I have the transparency feature turned off so my user interface look poorly. My iPhone 13 Pro Max is still using 40/50% of battery more in comparison to ios 18 and previous. I REGRET updating the system and I don't see anything being done to fix it...

I updated over 2 weeks ago. Indexing was over long ago.

4 days with barely any usage, 21% in a day is really not ok when with ios18 on the same device it lasted 3x longer. I use the iPad only after work for 30min or so, it used to last 2 weeks between charges, now 3-4 days. The issue is if I really use it for a couple of hours it depletes the battery completely.

The same issue is happening with me in my model 13 pro , replaced new battery og from apple service on 1 may 2025 after updating to ios 26 my battery issue started coming sometimes it stop charging when i plug in , and from a week a highly major issue is coming ie my battery is draining unnecessary without touching at night drop was of 15-20%

My screen freezes COMPLETELY and the battery drain is significant after this 26 upgrade. I had a brand new 16 that is suddenly a brick. I am so angry. I want to return this phone and buy one with an operating system that works. And don’t tell me to update apps and turn off options to fix this piece of s. This has ruined my phone.

There's something a little strange about the reports from Battery. I made a 1 hour facetime call this morning. After it terminated (and I terminated the facetime app) Battery said that Facetime had used 11% of the battery. When I checked battery a 1/2 hour later, it said that Facetime had used 19% (even though Facetime wasn't running). I just checked again - now about 6 hours after it finished, and it said that Facetime had used 25%. Can someone explain what's going on?

I spent a lot of money to buy the new iPhone 16 PM. At first, the battery worked well with iOS 18. However after the update to iOS 26, everything changed. It ruined my new phone, and now I don’t feel like I’m using a new device anymore. The battery is draining super fast even though the phone is new and the battery cycle count is only 45. I updated to version 26.1 today but the battery is still draining super fast. Why is Apple doing this to us and not fixing this major issue?

You just need to make note of the person you are responding to. For example you responded to my post where it says: "Oct 12, 2025 7:06 AM in response to martinjames1962".

That person did not provide their battery health which was the reason for my question and that person did not say their phone was brand new. I understand how you may have been confused, so hopefully that will help. It does make it more difficult when others simply provide "me too" posts without providing any information for a resolution.

I think it's actually very convenient for Apple supporters to put a blame on WhatsApp, however we've seen number of reports here from US customers not using this app (which is not that popular in US) yet still being affected by the issue.

Hello team Apple

i have iphone 15 pro max, in February 2026 will be exactly 2 years of use. 2 months ago i have checked my iPhone battery capacity and it was 91% and after the update of ios 26 it dropped to 88 last month and now to 87 ! Honestly it is very frustrating to drop this fast. This is not my first iphone but this is the first one that the battery drops quickly like only one month apart !! Can you do something abt it ?

Same issues, the batery in the best of cases is consumed around half of the time before updating.

Several day since the update has applied and the issue still continue.

Hope this issue won't be ignored as wifi desconections on iOS18.

Regards

I upgraded to 26.1 and the iPhone 17 Pro is great, but the M1 iPad is still horrible. I was getting 1 week of occasional usage before, now it's down to 2 days at most and the consumption is nothing, 4% Youtube, 1% safari, the other 80% idle...and I disabled already all the things I've seen in recommendations, from the new animations to the notification of apps in background, etc.

I'm genuinely looking for guidance on how to downgrade, at this point I'm also fine doing a system reset.
