My battery life was terrible
I followed the ifixit guide and the repair went fine until it came to removing the battery. It's glued in to the case and on the video they show how to pull the adhesive around the battery. This is actually next to impossible and both parts of the adhesive snapped. Of course ifixit offer another product to help in the event of this happening, some sort of microwavable heat bag which presumably melts the glue - I suspect they may have applied that before they did their demo. Anyway, I thought for what was supposed to be a cost saving exercise I wasn't going to purchase more products so against all of ifixit's advice I got a pair of pliers and yanked and twisted the battery out, releasing the potentially life threatening toxic chemicals into the air. After that they kind of leave you a bit in the lurch and just tell you to reverse the steps. I managed to do this, getting the little plugs back in was kind of a pain. I then switched the phone on, expecting it to crackle and ignite, but it actually just worked as normal and now the battery life is acceptable again.
This cost me $30. I'd rather spend $50 and have someone do it for me.
