Based on technical spec, my MBP can stay alive about around 7 hours on battery, however in real life, it can stay around 4 hours

Around 20% my mac goes into sleep mode and asks me to recharge it.

Answer:

You will get a message telling you your battery should be replaced.


In your case, the battery is indeed normal. The cycle count for the year is okay, the charge information looks fine to me (6702 maximum is right for its age). At the current rate of depletion you should have another two years life in it.

Happy to have helped. It was so useful that you published the details of the battery; I shall be reporting the post in case your user name should not be there. If the hosts agree they may remove those images but as the matter is solved, that doesn't matter.
