Normal battery degradation?

So I bought my S6231 last December, and have been using it between 15 minutes and 2 hrs per day on battery, with a recharge every 3 days or so, so I figure 100+ recharges so far.

Originally the battery was definitely giving me 3-4 hours on a full charge. However, nowadays I am lucky to get 3 hours with 2 1/2 more typical.

Should I be experiencing such dramatic loss of capacity after only 1 year / 100 cycles? Or should I be looking for another reason why the battery is draining? I don't think there is any new software that would be hitting the hard drive more often, for example.

 

One thing you could do is run a test now using something like battery eater pro. I recommend the idle test. Then run the same thing in a month or two to see where you are. Degredation is normal but a 25% loss in a year is a lot, unless you're underestimating the cycles. Anyway, I'd start with getting a baseline and go from there.

 

The lithium batteries that are used in most modern electronics lose battery life as a funtion of AGE, not just usage. And that cureve starts to accelerate after a while. On other words if you just sat the batter down in your drawer and NEVR used it - it would have the same problem you see there.


Just buy another battery if you need 4 hrs life. Dont waste your time other than that. Its not any fault in the laptop or the specific battery that you own. You can't fight it, mitigate it, or cure it. Its the nature of the material - and death. Its not escapable.
