Ongoing battery drain 16 Pro

[Velli]

I know, another “my battery drains too fast” thread… But I have to share my issue:

I have a 16 Pro, since launch. Battery health 90%. In the beginning my battery life was excellent, 7-8 hours on-screen use a day with plenty battery to spare. But basically since ios26 update, almost a year now, my battery life has been down the drain. Today I have 3 hours screen on, 2 hours screen off, with 19% left. It’s unbearable at this point. This was a day of light use, on days where I actively use my phone I am recharging at least once per day.

There is no single app that is the culprit. 16% drain is 20 minutes of Safari. 12 % drain is 24 minutes of LinkedIn. The rest is max 4% per app. So it’s a widespread issue.

I kept telling myself that it was just reindexing, that it’s a bug that will be fixed soon, etc. I’m one of those always telling people who complain after an update that they just have to wait. I’ve now waited for 10-11 months, and it’s still useless. I upgraded from a 13 Mini, and at this point the Mini had better battery…

I’m not even expecting any suggestions at this point. I guess ll I can do is wait for iOS 27, and hope for the best. I don’t want to go for public beta, because in my experience getting off the bet again meant re-install. On the other hand, that’s probably what I should do to try and fix this…

Sigh.

iOS 26.6. seem to have helped some but not everyone experiencing battery drain, have you updated and tested the latest version?
I'm using a 16 pro myself but haven't had any of the issues you describe so can't really help. But, I have disabled a few things that might be the reason I don't see these issues.

* I don't use any of the AI functions that comes with iOS 26.
* All background services are disabled
* I have uninstalled most social media ish apps (linkedin, facebook etc) only thing I do have is reddit
* BT devices I use are my airpods and Polar watch, that's about it.
* Make sure you have decent amount of storage free (if its a 256gb version, try and have around 20% free) this will stop constant maintanance and cut down on network usage.
* No VPN software more other than the regular Apple relay stuff.
* See if you can optimize safari, cut down on preload stuff, remove extensions, clear history and close tabs, prevent cross site tracking
* Have a look i privacy and security, location services and tweak apps and sites, set never or while using if necessary.
* Turn off Always on display

Above is a few things off the top of my head.
I have to say that 26.6 brought a bit of a boost when it comes to stand by time. It's holiday times here so don't have my regular usage pattern so hard to say how much better it is. It will be interesting to see what's its like on my regular commute and usage pattern.

The “you just have to wait” is a massive, perpetually damaging myth, that people have repeated so much that it’s “common knowledge”.

The battery life drop never recovers and you should not defend iOS updates with that myth again.

That said… people have overwhelmingly reported a 20% drop, occasionally 30% drop from iOS 18 to 26 on the 16 series. This “from 8 hours of SOT with battery to spare to 3 hours with 19% left” is not a common report. Sounds too awful.

If you’ve tried tweaking settings and it hasn’t worked, considering that battery life is that awful I’d just try restoring and setting up as new, honestly.

iOS 26 is bad… it’s not THAT bad.

Thanks. I have not installed 26.6 yet, but will today. I’ll go through your suggestions, and see what happens over the next days.

I think I found the culprit, and yes the problem was me being stupid, not the phone…

I never actually checked how full my storage was… I “knew” that it was only about half full. But apparently I accidentally downloaded a huge playlist at some point, which completely filled the drive. I deleted the downloads, and so far it seems better. I will see what happens after a few days. Thanks for the pointers 👍

Glad you found it. I tend to forget how much a full storage affects battery time myself. Has happened a few times over the years that I get a boost when clearing out stuff and making sure I have about 10-20% free space.
Back in the days its was obvious that you were running out of space and got notification that it was the case, now iOS generally does a lot of magic in the background before telling you its full and the maintanance magic seem to impact battery life as well.

Random but another thing that can improve your battery life is turning Adaptive Power Mode on😃
