Hi,
I know the battery life in OS X was never very good on the Probook line, but I am afraid OS X is also somehow destroying the battery.
Recently I found out that I can only squeeze out around 1 hour of life from the battery and then the laptop dies without warning, and just a moment before dying it was showing circa 30% charge remaining in the menu bar. In Windows 7 / 8 the situation was the same, regardless any brightness settings or wifi on/off etc. So I started investigating and tried to put a new battery from another, month old Probook to my Probook, and suddenly the battery life was OK, at 2,5 hours, and the laptop died when it should, at 0% of battery remaining.
When you open System Information, you can see the full charge capacity of the battery in mAh. The original capacity of the battery should be around 4400 mAh, which corresponds with what I have seen with the new battery in my Probook. When I put there the one which drained in a hour, it showed only 2300 mAh. I thought that the battery just degraded with its lifetime, because I used the laptop quite heavily. But when I looked after next two days, the capacity was only 1800 mAh.
I don't think the battery should degrade more than 10% in two days, that seems just wrong.
So I asked some people with a Probook who never installed OS X and had just Windows 7 on it. Virtually all of them said that when their laptop was new, they had a battery life of 5-6 hours, and after a year they still have a battery life of 4-5 hours, which is quite impressive and truly doesn't correspond with my experience.
I wanted to ask, does anyone of you have the same problem, or better, could you post your full charge capacity, which you see in System Information, along with some info about how long can your Probook last on battery in OS X / Windows, and how long do you own and use it?
Thanks in advance,
František Nesveda
