Is there an efficient way to calibrate the battery of my tablet in order to prove or disprove the very low battery backup than using some Apps.?

The context is that my tablet is giving a very low battery back up and when I contacted customer care, they are asking me to do a battery calibration by using some app. But, by some other posts in this forum and other help, I was able to understand that Battery Calibration apps does not make a much difference in battery backup improvement or to prove that my battery is really problematic. And there rises this question.

Thanks for your suggestions in advance.

And did you try that app? Because maybe, it could help, and then you could answer your own question just by doing it? –  ndsmyter Feb 16 '13 at 11:02
    
the app is on trial. It will take some time to get to know the exact result after some full cycles of discharge and recharge right? So this question is intermediary to that. –  RinoTom Feb 16 '13 at 11:03
    
Ah ok, makes sense :-) –  ndsmyter Feb 16 '13 at 11:41

The best method is the manual DIY method :D

Step 1: Drain your battery by using it normally until it turns off by itself
Step 2: Power-on your phone, if it wakes up and you see some power left, do step 1
Step 3: If phone is now drained to the point it can't wake up, Charge it to 100%
Step 4: Once fully charged, power-on phone, and charge it again. Leave it until completely charged
Step 5: Unplug, use, and enjoy.

This makes the phone remember the minimum and maximum voltage, discharge rate and other factors that constitute the battery capacity

WARNING: Do not do this frequently! It will put strain on Li-ion batteries that majority of phones use now. Do this if and only if you are noticing shutdowns on yellow battery bar, cannot charge 100%, and erratic battery capacity display. But still I do this once a month to keep my battery calibrated.

Actually I had done these steps after doing the recalibration using an app. But, it doesn't show any better improvement in battery backup. So may be my battery is running in bad state or these steps are not enough. –  RinoTom Feb 21 '13 at 13:39
    
If your tablet is a year old or more, and you're a heavy user, then it might be the battery that needs replacement. Are you experiencing fast battery drain? –  forums Feb 21 '13 at 16:42
    
My tablet is just only 4 months old –  RinoTom Feb 21 '13 at 16:46

I see. So tablet already has a faulty battery meter. You can use android's built-in battery graph in settings or other battery logging apps to convince them of consistently low readings –  forums Feb 21 '13 at 17:18
