There is no overheating.
The Battery is 26.5 Degree Celcius in day around 3pm.
Normally earlier Battery was near 35 Degree Celcius
Now it is 27.2 Degree Celcius. (10:58 PM, 23 Oct 2013)
Actually when in day I check it was 37%.
Around 3am today, it showed 4% only.
In day it became to 26.5 Degree Celcius in day around 3pm
What happened in between 12 hours that it gained charge?
Why Temperature is so different at different times and charge comes back?
Battery is now 32% with temperature of 28.2%
during 1-2 min the app I am checking is making it hot 1 Degree Celcius.
It means now it is discharging at normal rate.
Yesterday after 100% charge it showed 30-40% only after few hours.
Lets see what happens.
I have not charged it today
& will try to check its temperature.
This is certainly not a virus effect.

After I put my problem in BCMT,
Battery is behaving good.
If You are feeling that
Your Mobile is dead
or battery is not working fine
or Charging is getting delayed.
Don't panic. Just keep your Mobile phone warm.
That is all,
You have to do.
Should I put my mobile phone on Burning Flame
of Candle / Gas Stove
or put it an oven?
Keep it warm.
After charging keep it with you under jacket, in shirt
or in pant's pocket.
Mobile should be near your body and it should not exposed to room temperature.
If you attend call with phone to take it out.
Place near ear & face and hold / cover it with your hand perfectly.
It will get heat of your body and will not get cold as room temperature /
be prone to low temperature.
You may have to charge it twice immediately after first charge.
Do it immediately.
While charging, put mobile in any padded protection from cold.
It is good to provide any type of heat insulation.
If you have come out of home/office where you have not any kind of charing.
Just put it in your pocket.
Wait till it is warm.
This trick may work sometimes.
These all above tricks can be tried on Camera batteries also.
Those who are in Delhi.
