Super Easy Repair Worth Doing Yourself
Everything in my MacBook Pro has been working great since the day I bought it—with the sole exception of the battery. While it wasn't an issue in the first couple of years I owned the device, over the last few months my battery life degraded to the point that I'd be lucky to have my computer last more than 90 minutes unplugged.
The repair was... shockingly easy. I'd expected it to be somewhat of an ordeal, but honestly, the only remotely challenging part of the process is cutting through the adhesive that holds the old battery down so you can insert the new one.
I really only have three small pieces of advice:
1. Be liberal with the adhesive remover—especially for the larger middle portion of the battery. I did three applications total there, letting the remover sit for 2 minutes before cutting part way under the battery and repeating until it was removed—and was much happier for it.
2. Take the opportunity to clean out the MacBook with some compressed air. Mine was SUPER dusty when I opened it up.
3. Just a heads up that the extra drive tips are found in the blue base of the screwdriver. It took me a second to find them.
