Should have done this sooner...

Mijn probleem

Battery life was horrible...2-3 hrs on a full charge. Battery percentage would steadily fall, reach 30%, and shut off; and would not turn back on unless connected to a charger.

Mijn oplossing

Repair took about 30 min. I wouldn't consider myself a noob when it comes to things like this but I am by no means a pro, either. The instructions are really straightforward and easy to follow...and I took my time to ensure it was done properly.

Mijn advies

It's been three days since I completed the battery swap and everything is working perfectly. My battery life is great...the phone lasts all day and I come home with 65%-70% battery life on steady, moderate use.

My advice.... I was admittedly skeptical, I've heard stories of other places trying to pass off old and refurbished batteries as "new," so not buying directly from Apple made me nervous (which I couldn't do because my phone is out of warranty). However, this place is totally legit. No problems whatsoever and I would recommend this place to anyone. So if you are on the fence about whether or not you should buy from ifixit, don't be.
