Comment on Supercapacitors Batteries charges in seconds without degradingparent

My three-year-old MBP lasts about an hour. I think it lasted like 6-8 hours at first.

If it's under warranty, that's worth taking in. When I got my MBP repaired under warranty they also noticed my battery was doing worse than it should for the number of cycles and replaced it no questions without me having to ask. I believe rated is 80% health after 1000 cycles, and mine was somewhere around 75% after 8 or 900---you can check the these values in system information, I believe.

Warranty was only for a year. I had it repaired at some point for some heatsink issue, and they offered they could swap out the battery while at it (i.e. no extra labor). But it would've cost me 300$ CAD just for the battery, which seemed expensive at the time. Now I regret not paying for that..

Does it run the same OS, software, etc as before, though?
