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. 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. Unfortunately, about 3 months later, the new battery began to have another issue. It did not swell, but the battery would only last about 30 minutes to an hour. 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. 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 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. Does anyone have any other suggestions as to why the battery would be draining so quickly? Update:
Thanks!
mmm … CoconutBattery is showing a healthy battery and the charging logic appears to be working just fine as well. So let’s dig a bit deeper here, disconnect the MagSafe charger and run your system until it dies (30~60 mins?) don’t let it sleep! As soon as it stops plug in your MagSafe and quickly run CoconutBattery taking a fresh snapshot and post it here again.
