MPB Battery capacity dropping already after 7 weeks

[Brambo]

I've got my MBP C2D for 7 weeks. Battery capacity used to be at 5500+. Since a day or so it is dropping, and the battery won't charge beyond 96%, see picture.

Calibrating didn't help, charging overnight also didn't change anything.
I understand that the capacity of a rechargeable battery drops when used. But it seems to me the battery capacity is going down rather quick, too quick if you ask me. Any ideas on what to do?

I also have 21 charge cycles but mine says 99%.

It could be just the software bugging or something, I found mine said 96% a couple of weeks ago then straightened out back to 99%. I don't think these things are 100% accurate all the time.

My MacBook Pro is also 7weeks old, and it has been up and down for the last while, but I am not too worried.

My original battery is at 132 cycles, and 98% capacity, When there was a recall on these batteries, I did the replacement thing and did not send the original back, Glad I didn't because the new battery is at 22 cycles, and 88% capacity

 

[Karpfish]

what was the recall for?

You didnt send back the original? They haven't said anything to you?

wow compared to yours mine is pretty impressive, it's probably because i havent gone thru many cycles. i was going to take it with me on a trip, but i didnt.

Mine is also 7 weeks but with only 4 cycles and looks pretty good.

 

[Brambo]

Woh! that's a real super-charged battery you got there!
Anyway, looks like I'm worrying too much indeed, mine seems to be recovering also. But I'm still wondering how it'll be in a few months time...

 

[daneoni]

Im at the same both as you. 7 Weeks and at 96%...lame. I get 97% if im lucky, in fact i think i only saw 99% for a few days only. I do have alot of cycles though.

My macbook is 3 months old, with 43 cycles and 84% capacity. Somethings definitely wrong with it...

 

[Cybergypsy]

I had Apple replace mine the 2 one was sooooooo much better

 

[khunsanook]

7 months and 129 charge cycles later and I'm still at 98 percent.

Here's my C2D MBP,

oh my god, i have no idea what happened but i calibrated my battery and it went down 200 mAh from an earlier post when i was at 5495 mAh

 

[eluk]

It's improving.

 

[Brambo]

It's improving.

Man! Tell us your secret! What did you do? When did you calibrate? How?

That's what happened with mine, but it seems to be recovering to 5404 (coming from 5288) since my last charge. Strange.

I've got 14 load cycles and 7 weeks, and she's already fluctuating. 98, 96, 97%

I'm trying since it's new to do full drain and re-charges on the battery.

 

[chendo]

It's improving.

Did you do anything in particular to get that capacity?

 

[faustfire]

Me too! Don't know why or how though.

 

[SC68Cal]

Take it with a grain of salt. A lot of it. Frankly, the whole measuring battery capacity is so haphazard and unreliable I just don't pay attention to it.

 

[eluk]

Man! Tell us your secret! What did you do? When did you calibrate? How?

Did as per Apple instructions the day I bought it. It varies a little and today is slightly down.

 

[eluk]

Went by the book.

Mines topping 7000 now, crazy!
