Determine battery cycle count for Mac notebooks When you can top off! It's better for your systems battery. I have yet to do this, and told him this didn’t make logical sense, as for three straight months, I hadn’t installed one new program.ĭoes anyone have any other suggestions as to why the battery would be draining so - You don't want to discharge below the 1/3 point as you'll burn a cycle as the stress of charging a low charged battery is what kills them. The Genius Bar associate advised me to do a clean uninstall and reinstall of the macOS and still see if I was having the issue, as he assumed that the problem was caused by one of the applications''/programs that was draining the battery. I took it back into the Apple Store, and they ran a comprehensive diagnostic test on it (supposedly), which found no issues with the battery. It did not swell, but the battery would only last about 30 minutes to an hour. Unfortunately, about 3 months later, the new battery began to have another issue. Thankfully, (and probably due to liability reasons), the battery was replaced, as well as the bottom part that had been bent out of shape due to the swelling. I have a Mid 2015 15” Macbook Pro Retina that had a swollen battery, so I took it in for repair at the Apple Store.
