Battery Health

This is my first Mac, and is about a year in a half old, I have noticed severely decreased battery lifespan and am curious if anyone can give me some advice on if I should break down and buy a replacement. I have attempted to search around and find out what some of this means, but I haven't had much luck. Conflicting answers regarding the Charge Remaining.. That is such a low number, it has me worried. :\

MacBook Pro Retina Display Battery Health problem

Hello,

I was just wondering why my MacBook Pro 15" Retina Display, which is just 3 months old, would have only about 98% battery health after 23 cycles!

When i bought it i had ~102% so 8700mAh from 8500mAh! Now i can only reach 8349mAh anymore! Does anybody have the same issue or am I the only one with a bad battery in my MacBook? I know, that these numbers are not very accurate! But if there are missing 2% charge after 3 months...

Maybe it's only a similar problem to the following! I hope this will be fixed soon.

(If there are any Mountain Lion Developers in this forum... this is for you)

I also found a bug concerning battery charge! When my MacBook is fully charged, it says 100%, not really fascinating. But the thing is, it already shows 100% when there are only about 96% charge in the battery! So... I shut down my computer when the charging-light went green, reset the SMC and... wow... it's orange again!! So PLEASE fix this bug!

I don't know how to change system language so sorry for my german screenshot!

Is this normal: MBA Mid2012 Battery Health down to 80% @ 184 cycles and 24 weeks usage?

MBA Mid2012 Battery Health down to 80% @ 184 cycles and 24 weeks usage. Is this normal? Also, when I drain down to less than 5% battery indicator tells me to service battery. Should I be alarmed and have it serviced/have the batteries replaced?

Battery health deterioration

I've a MBA Mid-2011 model. As you see from Coconut Battery report; the age of the Mac is just 18 months and with 359 recharge cycles so far. The battery health has deteriorated so fast; now it hardly holds half-an-hour of power capacity.

From all the help and advice, I gathered from the web; I've tried SMC, PRAM reset and also recalibration of the battery. Also, upgraded to the latest version of the Mac OS X (10.8.2) in the hopes of finding some solution to this, but with no avail.

I understand that it should work for at least 1000 cycles or more. Could it be a faulty battery? Are there any other options apart from getting the battery replaced?

Macbook Air 2012 - After 220 Cycles health down to 88 %

Hi there,

 

My Macbook Air is down to 88 % battery life after just 220 cycles...  I tried everything to get it up again, but nothing helped.

This 12 % is nearly 40 mins of ussage and in many ocassions it´s really needed.

 

Do you guys know if that´s normal ? I´ve read that Apple guarantee that after 1000 cycles battery is still over 80 %. In my case that doesn´t seem feasibly.

 

Do you think I´ll get a new one ? I bought it at the Apple Online Store (cause the 8 GB RAM upgrade) but I have a physical Apple Store that I could go to.

 

Thanks in advance four your help
