Hi, you may try and recalibrate battery:
To recalibrate battery, charge your phone to 100% without interruption.
then discharge it normally till 0%(phone gets switched off).
charge it to 100% in switched off condition and keep it in that state for a little more time.
now switch on your phone in charged condition and unplug when ASUS logo appears.
keep the phone unused for 5 mins.
you will get far better battery life as the battery stats.bin file will be updated.
