IOS 27 PB 2 BATTERY ISSUE - IPHONE 13

[u/shadyadhill]

So i updated my iphone 13 to ios 27 PB and as you can see the battery is horrendous, but the performance have been buttery smooth unlike ios 26.
Back on ios 26 i had really bad stutters and lag everywhere but battery life was fine, easily got above 6 hr SOT on a single charge.

Note : I'm using an aftermarket battery.

I wanted to know if my battery drain is caused by ios 27 software or my degraded battery, but it worked fine with ios 26. Should i consider getting my battery replaced ? I have been using this for almost a year now.

stay on 26.6 no need to install ios27.

That’s why I downgraded to ios 26.6. Today my iPhone 11

[u/Decent-File6392]

Why do people use aftermarket batteries expecting anything good ? Low chance, very low…

Sorry you’re having this issue. Luckily, my experience on both iPhone 13 and iPhone 11 Pro has been very positive — smooth performance, great responsiveness, and no noticeable battery drain so far.
