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 . . .

My Problem

Battery would not hold charge

My Fix

Tedious but OK

My Advice

During reassembly, when reconnecting the battery connector, align the top screw hole with the screw hole in the pressure contact by holding them together with the sharp pointed plastic tool given. Then push the sharp pointed plastic tool tip into the screw . . .

The battery life for the phone was getting short so that I had to limit activities to keep the battery charged enough to last the whole day. Seeing that the new battery was inexpensive and came with a complete kit of tools seem very encouraging.

My Problem

Battery would only hold a charge for 24 hrs.

My Problem

Not used yet as battery of my older 4S hasn't begun to show signs of failure.

Replacement was ordered in anticipation of being needed before long.

Very impressed with prompt shipping, smart packaging of battery and tool kit and excellent instructions. I may not be able to wait until actually needed! . . .

My Problem

My old iPhone 4s original battery was draining from full to 1% in a matter of minutes and was no longer under guarantee so I chose the diy repair option.

My Problem

My battery was not lasting long and dying when it reached about 30-35%

My Fix

Repair was pretty easy but tedious. Only took about 10 minutes.

My Problem

My phone just could not keep a charge.

My Fix

Amazing. The biggest challenge was not losing those tiny screws.

My Problem

I ordered the replacement battery because my phone has gotten slower and slower when opening apps. Recent news stories about Apple deliberately slowing phones down to help battery life. So I decided to replace it to see what would happen.

My Fix

The repair was very simple. I was able to get the old battery . . .
