Q: Battery problem!!!!heating up while charging and battery loosing in short time

Hi swaraj.vidhate,

If you are experiencing what appears to be unusually short battery life, you may want to check out the "Power/Battery: Battery life seems short" section of the following article:

In particular, the Restore iPhone step will help isolate if any potential issue is software or hardware related.

With regard to the iPhone warming during charging:

When using the device or charging the battery, it is normal for it to get warm. The exterior of the device functions as a cooling surface that transfers heat from inside the device to the cooler air outside.

If you are still having issues with the battery life, or have any further concerns, there is a link to Apple iPhone Support at the bottom of the Hardware Troubleshooting document; I am sure they would be happy to be of assistance.

Cheers,
