A question about the Macbook Pro 13" battery health.

Hi. I just got a new Macbook Pro 13" i5. The battery health is 88% (using iStat Pro Widget) but I can get about 4:30 to 5 hours of battery usage. Is this normal?

Another thing, The bottom of the body is really hot but I can't feel any heat on the trackpad or the whole keyboard area. Is there any heating problem with it?

Thanks.

If its brand new, it should be 100%. You should take it to you nearest apple store (if you have one) And get them to check it out. The design capacity of the mbp 13 battery is 5770mAh. What does iStat say?

The bottom tends to get hot.

Have you fully charged it and allowed the battery to run down until it tells you to plug in yet? Many Mac laptops report inaccurate battery health until the first charge cycle - my retina MacBook Pro arrived saying 96% health, but it's been at 100% ever since that first charge.

No, it's not normal. It is perfectly normal if your battery health (maximum capacity) is more or less than 100%, even when brand new, or if it fluctuates up or down over time, but not as low as 88% when brand new. For further details, read the CHECKING STATUS AND HEALTH section of the following link.

This should answer most, if not all, of your battery questions:

You don't need to do that with current batteries, and the built-in batteries in the newer Mac unibody notebooks come pre-calibrated and do not require regular calibration like the removable batteries.
