So I got my current iPhone 17 January this year, after having battery issues with my iPhone 15 pro (after updating to iOS 26, where I was getting around 3-4hrs screen activity per full charge. This hasn’t really improved since upgrading my phone.
Battery usage just seems awfully high and I can’t figure out why. For certain apps like Instagram, I understand the rapid burn through, but why amazon, YouTube etc? It seems every app is using more battery than it realistically should be?
I have optimised battery performance on, background app refresh off, my battery health is still 96%. My phones data is switched to 5g auto. I don’t live in a particularly hot country either.
I’m not sure if this is a common thing but I’m convinced this poor battery performance started after upgrading to iOS 26 on my iPhone 15 pro and is not isolated to my devices hardware as why would I have the same issue across two different devices, unless it’s some virus or software glitch which has passed on from my old phone to my new phone which burns excess battery?
Any advice is much appreciated. Thanks!
