Iphone 5s Stuck On Apple Logo After Battery Replacement. Connect iphone to computer then do the apple power on. Force rebooting forces your iPhone to turn off and then turn back on no matter what condition it is in.

Is that common to happen to an iPhone 5s. Restore your iPhone by following the on-screen prompts. If your iPhone is stuck on the Apple logo If you have iOS 13 or later and have tried restoring your iPhone from a backup or migrating your iPhone from a previous device then the Apple logo and progress bar may display on your screen for more than one hour.
After a bettery remove and replace not the RR we all hope for her phone did similar things as yours.
Let go when iTunes or Finder detects your iPhone. Phone goes into a boot loop where the apple logo would appear for around 4-5 seconds before going black and then repeat after 2ish seconds. Usually the iPhone is frozen on the Apple logo screen and wont turn off. You left out the part about keeping track of screw sizes and non-magnetic screw.
