Battery Drain on iOS 26 and iOS 26.0.1.

Good morning everyone,

I would like to report a VERY SERIOUS problem with the battery and performance.

I have a NEW iPhone 15 with 100% battery capacity and only 22 cycles (which I did myself; when it arrived, it was at 0).

However, after updating to iOS 26 (and even with iOS 26.0.1, the situation remains the same), I continue to have VERY SERIOUS problems with the battery life of my NEW phone.

Today, I was busy all day and did not use my phone from 8 a.m. to 4 p.m., yet it still dropped from 90% to 45% WITHOUT DOING ANYTHING. No apps were open, the “Refresh apps in background” option was not enabled, the screen was set to turn off automatically after 30 seconds, and automatic brightness was enabled. So it's definitely not the phone's fault because it's BRAND NEW with a 100% ORIGINAL battery, nor is it the settings because it was in PERMANENT POWER SAVING mode. So the fault lies solely with iOS. There are no excuses.

I am writing this message to urge Apple to resolve this issue as soon as possible because, from what I have read on X, I am not the only one.

Has anyone else had this problem?

Thank you very much and have a good day.

iPhone 15, iOS 26

Had the same issue on my iphone 16 after upgrading to 26.0.1.

i did these things and battery life seems to be normal. Following are the things i did.

update all the apps manually and do a hard reset by pressing volume up, release, volume down, release & finally hold power button until you see the apple logo. This will force your iphone to restart.
turn on reduce motion from setting. This will disable lockscreen 3d image feature. But maybe this helped to reduce my battery draining. (accessibility—> motion)
turn on the prefer cross-fade transitions(accessibility—> motion). This will disable modern transitions and new glass effect.

somehow these things prevented my rapid battery draining issue.

also please note that for first 2-3 days there are some background processes running to indexing after the update. So maybe that will also take a huge battery power for that process better to give 2-3 days and then try these methods. All or one will help you.

When you tap the apps with the exclamation point what does it indicate?

What does Home & Lock Screen show? It’s cut off in the bottom image.

No, Apple does not permit a downgrade. What 5 or 6 apps are consuming the most battery capacity on a daily basis? Do any of the apps show background activity?

Removing Facebook from my phone has helped. However, battery life is still poor. Battery health is 85%. Apps are up to date. Apple needs to address the issue.

I had the battery problem initially but it went away after I followed the instructions on the following video. I hope it helps you too.

Completely unrelated hardware issue.

I suggest you take your phone in to be examined.

I've tried everything, resetting network settings, hard resetting by pressing Volume Up + Volume Down and holding the power button. I strongly believe it's a software optimisation issue.

It certainly is possible. We can't rule out app usage of background processes or indexing is still going on if you are seeing high usage of Home & Lock Screen though at this point, without seeing the apps consuming the battery.

The next update is currently in beta and being testing and as I said before, we are unable to comment on the issues that have been resolved relating to battery usage in that update. No release date has been set, but you may find improvement when it is officially released.

I updated to 26 on the day it came out on my 16 Pro Max, battery was dicey for a few days and then corrected itself, but 2 weeks later suddenly out of nowhere, the battery has completely tanked, this morning October 3rd 2025 I left the house with 51% at 6:30 am and ended up on 20% by 10:30 am with my screen on time being only 1hr 40mins?? The standby time has also worsened severely, I’m losing 20 a 25% battery overnight, for comparison back when I had the 13 Pro Max on iOS 15 that phone never dropped more than 5% which is honestly unacceptable. I have no idea what’s going on. Has anyone else experienced this? Where the battery corrected itself and then weeks later went downhill?

Your first 7 apps using the most battery capacity are all non-Apple apps. They account for almost 80% of your battery consumption. How is this Apple’s fault?

I get it that those are the apps you want to use and give enjoyment etc. But you need to be reporting the issue to the support teams for the apps causing your issues. I use none of those apps and I’m getting the best battery life I’ve ever had on an iPhone.

Sorry, you have an app issue, not an iOS issue.

Trust me, way more than 300 people are having issues with Meta apps. Facebook is really the only app doing better than in the past. Instagram and WhatsApp are really struggling right now. Just keep checking daily for updates. I’m a photographer and Instagram is a big deal for many photographers. But people are struggling because Zuckerberg doesn’t care. I get it.

Report your frustration to Apple and on Meta’s apps. Truthfully, they’re terrible towards their customers.

I am charging my iPhone 13 right now because it shutdown without warning on me. It was in low power mode at 47%, but instantly went from 47% to 10%… INSTANTLY! And I had already done all the things recommended to reduce battery drain. The problem is 100% software!

Do not try to gaslight us by saying it’s our fault and we need to be patient. ios 26 is bad on battery reading. Hopefully it improves in a few days, and hopefully there is an update, but the ios is messed up!
