My Problem
My iPhone 4s battery was weak and running out of power after a couple hours of use.
My Fix
Your iFixit video was very accurate and I am glad I bought the tools with the battery. Everything went well!
My Advice
The tools are critical to a successful repair, so I recommend you buy them with the battery.
One Comment
Without your efixit video I would not have been able to replace the battery.
