Should I Replace My MacBook Pro?

-

i'm concerned battery life of macbook pro. i've had on month , istat pro says health @ 97%. i've charged today , went down 100% 95% in 5 minutes. in fifteen minutes down 92%. on average, i've charged everyday since got it. it's gone through 36 cycles. loses battery life when wake sleep. i've never been able use more 5 hours.

yesterday, brought take notes @ uni. in span of 2 hours , 30 minutes battery depleted 48%. had been using note-taking program journler , maybe 15 minutes of internet use in all.

there wrong , should replace it? i've checked other forums , have seen drastic improvement in battery life 2 or 3 weeks after got it. mine, however, doesn't seem improving.

p.s. sorry if sounds i'm having nervous breakdown. want make situation clear possible.
 

battery health fluctuates; being @ 97% normal , have shipped @ 97%, there variances in batteries. mine 17 months old, , istat menu(and coconut battery) rate battery @ 86%, few months ago @ 84%, before 89%, checked maybe last month , 90%.

far lasting 5 hours, first remember it's "up 7 hours," assuming have '11 since it's less month old, you're doing 5 hours doesn't sound unreasonable.
