Battery Drain on iOS 26 and iOS 26.0.1.

Could you scroll further down and upload your App and System Activity Usage as well please?

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.

Mine too after update to 26.0.1 my battery draining fast.

What is your Battery Health and what apps are consuming your Battery at Settings > Battery?

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.

What does the Battery settings pane say is using your battery?

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!

I have an iphone 13 pro with 94% battey health on ios 18.7 it lasted me the whole day with 5 to 6 hours of screen on time with this mew update ios 26.0.1 (4 days post update) i find myself having to charge the phone twice a day maybe 3 times and it’s so bad that i find myself losing aroud 10% every hour with the phone idle and no apps nor bothing running in the backround no app refresh no location on no nothing

And so the saga continues. Used my phone this morning like I have done for the last two years. Read and replied to a few texts, read and replied to a few emails, made several phone calls, no web searches, no instagram, no news apps, no YouTube. I went from 100% at 6:00 am to 35% by noon. Before iOS 26 I would still be at or near 75% during the same time. As a repeat, battery health went from 100% pre-update to 80% post update. Jeff, if all of us are at fault and Apple has done nothing wrong, please explain the drop in battery health within minutes of updating to 26? Also, please explain why it takes 4 to 5% of my battery life just to do a restart on my phone.
