mbp battery health just went from around 70% to 55%

how many cycles? if it drops below 80% before it hits 300 cycles then yes you can get a free replacement.

 

have you ever calibrated your battery?

 

How long does an average charge last?

 

i would say calibrate it one more time and if it is still acting weird bring it in.

 

Send it back to apple.

 

ha yea or do that

 

thats definitely too low... I have 88 cycles with 100% health

 

I'm just over a year, at 95 cycles and 91% health. So for you, get a new battery for sure.

 

Sorry to hijack, but I am experiencing a similar dilemma.

My MacBook is 2 1/2 years old. Though the Cycle Count is only 104, my Battery Health is a paltry 57%.

I also try to recalibrate my battery and I have the latest battery firmware.

I know my battery isn't as fresh as the OP's, but, given my Cycle Count, isn't this also abnormal?

Thanks!

 

They replace batteries? Can't believe that... Few years back I had Thinkpad X41 and in a year, I've butchered my battery (from ~6h to 2.5h), but I've been going through some 3 charge/recharge cycles a day ;-)

 

Yes, I had them replace the one on my Macbook also when I had one. They mailed me the new one first, then I had 2 weeks to return the old one. They put a $129 hold on my card until I sent it back, but I agreed to that. The other option is sending your battery in and waiting for Apple to send you a new one (so you must go without a battery for a while), or going to an Apple store.
