Battery life always decreases after time, but I think 90% during 1 year and 4 months is a bit too fast. [br]

Do you feel like there is a 90% decrease in battery life or do you think it feels to be less? [br]
If you feel like it hasn’t lost that much battery time, it’s probably the program that is wrong. If you feel like it is correct, I don’t think it’s a normal decrease in battery time.
