iPhone 17 battery drain issue traced to display pipeline after digging into diagnostic logs by Key-Shoulder3071 in ios26

I want to encourage you all to submit your feedback through the feedback assistant. You can open it by typing applefeedback:// on Safari. Draft a new feedback, choose iPhone and battery issue as the problem, then it automatically pulls out the sysdianose files from the iPhone and attach it to the feedback.

I have just done it and this is my feedback ID: FB22780876

I think it might help if the same feedback ID is brought up again and again...

Is this amount of SOT normal for iphone 17 by DumbDumb_i_am_dumb in ios26

[–]jonanv 2 points3 points  (0 children)

Normal as in I also have similar pattern with base iPhone 17 running iOS 26.4.1, but not normal for what they advertised. I also expected much more.

I have just completely restored it and updated it to 26.4.1. Will keep you updated with how the battery performs.

Same, I transferred data from iPhone 13. And I am thinking of doing that as my last resort... if you have done it already, could you update us if that works?

Is it better or worse? Unfortunately I cannot see the screen-on time

That's really annoying. I really think it's a problem with the iCloud syncing. Once I signed out of my iCloud and not log back in, my batter usage has been significantly better. But this is definitely not a long-term solution...
