After a new update, you might feel the device is warm. You can wait for couple of days’ post update. Also, to be noted that phones heat up under intensive usage such as gaming, prolong use of camera or under extreme temperature. 
Please follow below steps may improve battery backup: 
1. Close apps that are not used (Bluetooth, WiFi, GPS, etc.)
2. Adjust sleep time and brightness (Settings > Display)
3. Boost memory when you see memory consumption is high with no app running,
4. check for background running applications, stop/disable unwanted apps, you can manage apps from auto-start manager. 

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.
