Battery Health

Hi veerainpatel

What happens with most laptop batteries is the laptop is constantly plugged in and that over time reduces the lifespan of the battery. My recommendations above were if that is the case. If you use your laptop on batteries on a regular basis, all the better
for the health of your battery.

It is normal to have an initial drop in the charging capacity of a new battery, but that will level out, don't worry . . .

 

N97 mini battery level drops suddenly

I've observed my N97 mini's battery level dropping abruptly from 4 bars to 1 bar (with low battery alarm). The phone's slightly more than a month old and using the latest 11.x.x firmware. Did a bit of googling, and found several suggestions on how to save
battery (turn off everything 'smart' on ur phone). That's not the point anyways. I need to find out why the battery level drops suddenly (like what happens when ur battery's dying out), and *not* why the battery lasts X hrs. I'm not sure about this, but I
think this mostly happens when the battery level is slightly below max, and I use any app that needs the GPS functionality. But then, there doesn't seem to be any problem with the GPS hardware in the phone, 'coz it usually gets a GPS lock in less than a minute
(mostly within seconds). Could it be related to the algo used to show the battery level, or is it that its my battery that's faulty? Any others out there having the same problem?
