After updating my iPhone from iOS 18.5 to iOS 26, it completely stopped working properly. The Wi-Fi turns off automatically whenever the screen goes dark, the system is lagging terribly, and the worst part is the battery — it won’t charge at all. It stays stuck at 1%, and after a short while, the phone just resets itself (probably because the battery is actually empty), but it never charges beyond that 1%.
Has anyone else experienced something like this after updating to iOS 26? If so, how did you fix it? I’d really appreciate any help or advice.
Im Using iPhone 11 Promax
Beta 1 versions are usually quite laggy, especially on devices with older hardware like the iPhone 11 Pro Max. That’s completely normal, and Apple will gradually improve performance in later beta releases.
I usually restart my iPhone if it’s not behaving as expected. However, if you feel it’s affecting your daily usage, I recommend downgrading to iOS 18.5 or waiting for more stable iOS 26 beta updates.
You can find the guide for downgrading without data loss here:
This update bricked my phone, it won’t charge, and its so dead it won’t recognize when I plug it into a computer to try a downgrade.
Been charging for a couple of hours now and nothing. It does recognize its plugged in, and the time shows correct on the screen.
Is there a way to downgrade the iPhone without turning it on? cause 1% doesnt last long and it keeps shutting down the phone in a short while after I turn it on.
