4s battery replacement

My Problem

Battery was down to 70% of original capacity according to Battery Doctor app.

My Fix

The screws are incredibly small. If you have trouble taking the screws off the bezel, you might want to re-evaluate the replacement, the screws inside are smaller. If you have poor near vision, you might not be able to get the screws and the pressure sensor lined up properly.

My Advice

I would the replacement part tray while swapping out the battery.
