It's been about a year I purchased a my Airpods and have never misused them like dropping in water etc. Recently I've noticed that i'm getting little over 3 hours of music/movie playback from Airpods. It used to be over 4 hours earlier. Checked this on both my iPhone & macs. Also the left airpod now seems to have lower battery. All the time. It discharges till 30% evenly, both right and left, then all of a sudden, the left starts to drop drastically. Typically at twice the rate of right airpod. For example, when right would be 21%, left would be 9%. And when the left goes to 0, the right still has 9-10% left in it. Then as soon as I plug both in the case, the left shows 12-15% charged and right 10-11%. The music continues until the left drops to 8-9% and goes dead. I've tried discharging both of airpods till zero, reset the airpods, reset connection to mac and iPhone. At this point I need to know whether this is a hardware malfunction; cause if it is, I'll need to give Apple center a visit.
