I have just installed Ubuntu 14.04 in my new laptop. Every thing is fine except the battery timing. When it is 100% fully charged the time starts from 16 hours and drops to 2 hours in just seconds then after that it again starts to increase from 2:30 to 2:45 from this to 3:00 and then to 3:30 and then again to 3:03 and it continues to change and sometimes it will start to decrease and then next moment it will start to increase. I am worried about it what should i do is it damaging my battery. Is there any solution to it?

Laptop battery life can become unpredictable when it is on the verge of going completely bad. Occasionally, and by that I mean one time out of ten, I can wake up a purportedly bad battery by repeatedly running down its 2-20 minute life span and putting it on charge until it thinks it is full, and after a few such cycles it wakes up and charges very long and then runs for ten hours or something incredible.

So just to be clear, it may not be a software issue, or even a laptop issue. I'd hate to have you spend a lot of money on a new battery for you to find out, but you may need to. If you give me the brand and model I'll see if I can find a good deal under $25.

  • There is rarely, if ever, a good reason to install windows. Let me put it this way, Do you intend to connect it to The Internet?

  • @user4687489, I take your question to mean, will the battery continue to get worse. The answer is, "probably", but in actuality, using the method I described, it could get better. Most laptop batteries use multiple parallels sets. The laptop can run with only one set. Most laptops use two sets. Some laptops use three sets. Each time a set fails, you lose that much capacity, so if you had two sets to begin with, the amount of capacity you would lose would be half.
