I picked up a 2012 13" Retina Pro for cheap from a friend. The battery only has 179 charge cycles, but it's not lasting long for what I use it for, so I've been thinking about having it replaced. It was a backup laptop for my friend, and for me, my only use is terminal (ssh / programming), and safari with 4-5 tabs. The issue is I'm only getting about 3-4hrs tops... and this is with the brightness set less than 50%. For a battery with only 179 cycles, I expected 6+ hrs using terminal and safari. (No youtube or Netflix either). So my question is, can I pay the Battery Service fee to have it replaced? Or will Apple refuse until the battery is failing? The other issue is that the keys are worn with a lot of wear and although they all work fine, I know the battery/top case comes with the new keyboard. I'm just not clear if Apple replaces if you pay, or if they only replace if they decide you need it (and you pay). Thanks.
