Hello, I took delivery of a brand new MBP 13" base model last week, direct from Apple. I installed my apps, one of which is battery health, and as I've checked it over the last few days, it's gone from 100% when new, to now sitting at 95%. Bare in mind, the laptop has now 5 charge cycles on, so I wouldn't have expected this to move. Is this normal, or do I potentially have a defective battery? Many thanks.
