I have a Model A1398. I recently bought a replacement battery from you and installed it. With constant use it runs out of charge in about 8 hours. What is the expected life of a charge?
Thats a hard value to define! Just like a car having two exact cars one with just one person in it and the other with a whole family and luggage the distance the car can travel on a tank of fuel will not be the same. This same problem happens here as the applications and what they are doing will effect the systems run time. When I’’m writing I can get about 8 hours so thats about the best you’ll get. If you are watching vids or other heavy CPU/GPU processing your time will be less unplugged.
