Hi guys, I've had my MBP for about 4 months now. The battery health has always been around the mid 90s for the entire time. I went on vacation for two weeks and left the laptop alone during that time. Now taht I'm back, I noticed that my battery health is at 61%. It's been around this mark for a few days now, and it it only lasts about 1.5hrs if it is not hooked up to the charger. Is there any way this health can bounce back, or am I screwed?
