iPhone 4s battery replacement instructions could be more detailed

My Problem

My old battery would only last a day, fully charged with minimal use.

My Fix

Went well. Relatively easy procedure. After completion, phone would not turn on until placed on charger. Then was searching for Wi-Fi without success. It Then turned of and would only intermittently flash the Apple logo. I reread the instructions and all the comments by people who encountered difficulties. Opened the phone and put a slight bend in the copper clip that contacts the metal plate in the back cover of the phone. It then worked perfectly. I assume I flattened the clip slightly when replacing it.

My Advice

1. Diagram with parts named so problems post replacement are more easy to troubleshoot based on other's comments.

2. More formal instruction on troubleshooting problems resulting from procedure

3. Suggest instruction include working on static free surface, Not touching metal and magnetic tools to other components in the phone and suggest the use of a magnifier.
