Hey everyone, I'm new to this forum, but I just had a question about my battery for my MBP bought late Feb 2016. It's been around 40 days now and I'm on 20 charge cycles + I have 6528 charge capacity. I usually use my MBP for uni and it goes down to about 50-60% before I'm able to fully charge it again at the end of the day. But sometimes it goes lower. Is this normal? Or should I be concerned? Thanks in advance.
