97%

[BigJohno]

How come my battery is only showing a 97% charge even when plugged in? I have a brand new MBP.

Thanks

Have you synced your battery lately?

calibrate it. Unplug the power. Pop in a DVD and let it play until the computer goes to sleep at 0%. Then plug it back in and hopefully it should go back to 100%.

Calibration usu. does the trick for me.

If you plug in your computer when the battery is at 93% or higher, it won't charge it. This helps prevent overcharging.

You should also calibrate your battery every month or two to ensure that it's capacity is being read correctly.

it's normal, here's my answer from a previous post.

here (http://docs.info.apple.com/article.html?artnum=88344)'s what apple says about it and for those too lazy to click, here ya go
Some PowerBook G4, iBook, MacBook Pro and MacBook computers may not show the battery as 100 percent charged in Mac OS X, even when the power adapter is plugged in. The battery appears to stop charging between 93 percent and 99 percent. (PowerPC-based computers may stop charging between 95 and 99 percent; Intel-based computers may stop charging between 93 and 99 percent.)

This is normal. The batteries used in these computers are designed to avoid short discharge/charge cycles in order to prolong the overall life of the battery. Because of this, when setting the Mac OS X battery status menu bar icon to display charge state by percentage, you may notice that the reported charge stays between 93 or 95 percent and 99 percent. When the battery level eventually drops below 93 or 95 percent, it will charge all the way to 100 percent.

well, this thread had gave me a good sleep option, I was worried that, after the battery update, mine battery was a candidate to be replaced.... hopefully, it will be normal, now I plug it, below 85% and....everything is alright...

love my MBP, good night!

97% is great mine is at 89% but it changes evry day.

After that battery update my battery dipped to 71 after calibration, and has climbed back up by itself to 89. So weird.

Before the update and calibration it was 93 give or take 2%.
