LCD flicker and power button issue after batter replacement

I started replacing the battery on an iPhone 5S but I'm having issues:

I can boot up the phone by pressing the power button, but once it's booted it doesnt seem to work anymore. Unless I press it 3 times, then the emergency menu pops up.

It also works if I press the power button if the phone's locked. But I can't lock the phone if I press it again. Volume buttons also don't work.

Also having issues with LCD flicker, but this could resolve by itself?

I checked the upper component cable but can't see any damage. Also didn't pry there. Very first time I have this issue, especially because the cable doesn't show any damages at all.

Same issue happens with another battery and with the original battery.

Any ideas?

*edit: the very weird thing is: when I want to lock the screen with assistive touch, it doesn't work either. Looks like a software issue then? Same problem after reset

  • *edit2: after connecting to wifi ( and auto set right time) it all works again.. Except the flicker , but I assume that's some static that should go away by itself?

the flicker is USUALLY the screen callibrating to the phone. i usually tell customers to give the screen three days to let it settle, and if it continues, to replace the screen.

Just an FYI, screen flicker commonly occurs on iPhone screens when you unplug the battery while the screen is turned on.

It seems to go away faster the longer you have the screen off.


eh. i turn every iphone i do off. and it still happens pretty frequently. (using OEM parts for carrier warranties) and im pretty sure the iphone was off whilst he was changing the battery. though id be quite impressed if he could do it without the phone turning off.


Pretty bad luck you got there, I rarely have this issue occur. I use all aftermarket screens though.


Thanks. The flicker resolved after a few hours. The issues with the power button etc still weird me out. All was solved after connecting to wifi and having the date set right :/ .


the date and time can set off a lot of problems with a device. dont let it get to you. i have seen much more obscure problems from the time an date. (wont charge while on, the home button not working, texts not getting through, but able to send them, etc.) date and time problems are common if its not set right. and i was confident it would resolve itself. our shop has done over 250k repairs as of last month. ive seen it too many times to count.
