Messy iPhone 5s Battery Replacement
A couple of months ago, my four year old iPhone 5S had a severe shutdown. It was all black, and wouldn't start until after a couple of hours connected to the charger. I panicked, thinking the phone was dead.
Luckily it booted up again, but afterwards I have had to charge my phone every night. If not I would risk a shutdown the following day.
The repair itself was moderately difficult. Firstly, the plastic bezel wanted to seperate from the glass panel. With a handy plastic opening tool, I got the screen assembly up and supported with a hair tie.

The touch ID cable bracket was easily removed with the spudger. With the battery ready to go, I started to work out the adhesive strips, but disaster! I put too much power and tore them both off. Hair dryer and plastic card to the rescue.
I managed to get the battery out, leaving it with a significant bend. Good thing I let the phone shut down at 1% battery level. Removing old adhesive and applying new strips, while making sure to not touch the new adhesive, very important.
Replacement battery goes in, easy. Reassembling the touch ID bracket was difficult. The adhesive tab was in the way due to poor bending and tucking, but eventually I got the bracket on. Assembling the display back on was a little tricky, making sure to get the top of the display in place.
Success! My phone booted up as normal, following a hard reset.
1. Discharge the phone! Even if you are super careful, the battery bends easily.
2. Be patient with the adhesive! Try to be as gentle as possible. Slow and easy does it.
3. Supporting the display 90° will simplify the repair. It also helps preserve the phone.
4. Have a magnetic tray. The screws are tiny! Very handy, if you have a messy desktop.
