iPhone 3GS Battery Replacement

Mi Problema

I got a used iPhone 3GS via Craigslist a few weeks before leaving for a year long trip to Africa. It performed wonderfully! However, the combination of it being my only source of internet connectivity for the year and it coming to me used meant the battery couldn't hold a charge! Getting it fixed in Africa was an option—an expensive one! I decided to wait until I got back stateside to decide what I was going to do about the battery.

Having Apple replace the battery seemed like a waste of good money better spent on a brand new phone. Likewise was sending it off to a 3rd party repair service (I didn't think I could live without my phone for 2-3 days). I also was a little leery about using a local service without having any testimonials to refer to. So I finally ordered the battery, a suction cup, and some extra spudgers from and got to work!

Mi Solucion

The repair went smooth. I unboxed my iFixit purchases and I sat to work on a flat surface with an adjustable lamp so I could be sure to see everything. The 3GS battery guide was great, and so were other people's comments on things to look out for.

My replacement experience took about 30 minutes, as I didn't want to make any stupid mistakes and break any cables or scratch any circuits.

It took a while to separate the screen from the body of the phone, but patience and the spudger helped to ease it loose. The other two things that added lots of time to the replacement was accidently discovering that I apparently have a foreign iPhone without the locking tab discussed in Step 6 (the ribbon cable just slides up out of the socket), and that the battery was solidly stuck to the bottom case due to the adhesive (and very heavy use in Africa).

I loosened the adhesive by placing some napkins in a frying pan and then placing the iPhone on the napkins. I set the heat to high and let the napkins get hot enough to where it would be only slightly uncomfortable to the touch. About two minutes of that heat and the adhesive loosened enough to where I could use the spudger to pry the battery from the bottom case.

The new battery works like a charm! Now that I've done this one repair, I could probably do another in about ten minutes, with most of the time devoted to either separating the screen from the case or liberating a stubborn glued battery from the bottom case. Thanks, iFixit!

Mi Consejo

• Read all the instructions first (paying close attention to any of the warnings in red) before doing any repairs.

• Peruse some user submitted reports to make sure you aren't caught off-guard by a first repair.

• Have a work area with plenty of light.

• The old battery can be really stuck to the bottom case. The layout of the adhesive on the old battery is just like the adhesive on the new: it's all around the edges. If you think you're using too much force in removing it, then carefully heat the bottom of the phone for a few minutes (I used a frying pan, several napkins, and enough heat and time to simulate heavy phone/data usage). The spudger should then be able to liberate the battery from the bottom of the case.

Happy iFixing!
