Hello. My iPhone 5 (1st generation) running iOS 10.3.3 has a broken power button. I was able to to manage locking the screen using Assistive Touch, but I haven't found a way to completly power it off. Can you help me find a way to power down my phone?
Just hold down the lock icon on assistive touch until the power off dialogue appears, i do the same on my 4s. Remember that when the phone is powered down, with a broken power button, the only way to turn it on again is by plugging the phone into a power source.
