========================================
Facing severe battery drain issue. There is definitely a bug with software, the idle battery drain is too damn high. To make it worse, the phone struggles to even give a screen-on time of 3 hours now and refuses to charge till 100 even with the supplied charger. One of the most peculiar thing i found out was my phone died due to battery drain, i connected it to the charger and booted it, and suddenly the battery is at 56% ?! Can someone please fix this? It's a very serious issue considering the times that we are living in!

Please follow below steps may improve battery backup:
1. Enable “Power saver” (Settings > Power management)
2. Close apps that are not used (Bluetooth, WiFi, GPS, etc.)
3. Adjust sleep time and brightness (Settings > Display)
4. Boost memory when you see memory consumption is high with no app running,
5. check for background running applications, stop/disable unwanted apps, you can manage apps from auto-start manager. 

You may also 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.
