Hi Realyashdeep,

How much battery is draining per hour and in idle mode?

Your device seems to be on the old firmware. Please update your device to .186 firmware

You may monitor the battery performance after the updating the device and follow the below steps.

1. Check which apps are draining your battery
2. Uninstall apps/reinstall them
3. Never manually close apps
4. Remove unnecessary widgets from the home screen
5. Turn on Airplane Mode in low-signal areas
6. Go Airplane Mode at bedtime
8. Turn off notifications
9. Turn off GPS when not in use
10. Enable Power Saver Mode
11. Dim the screen – intelligently/ Decrease screen timeout/ Stop vibration
12. Let your phone battery die once a month
13. Restart your phone

Let us know if you still face the issue.

If you have not received the update, you may manually download the firmware.

You can also go to ASUS official website to download newer firmware and instruction manual.
Note:

    Please make sure the firmware SKU you download is conformed to what on your phone, eg., WW -> WW, CN -> CN, TW -> TW. Incorrect SKU will lead to update failure.
    You can not change the SKU from one to another, eg., WW -> TW, and also can not downgrade your firmware, eg., V2.20.40.13 -> V2.19.40.18.
    During update process, please charge your phone with AC adaptor or make sure the phone has at least 15% battery life.


Steps for update:
1. Go to "Need Help?" page of ASUS official website http://www.asus.com/support to download ZIP file of firmware.
    Note: Double click the ZIP file after downloading is completed. If the content is another intact ZIP file (as shown in red on picture below),
              please upzip the file again.
             If the content is not an intact ZIP file (as shown in yellow), you do not have to do anything.
             Close the ZIP file after check.
   


2. Connect your phone with PC via micro USB cable, and copy the ZIP file to the root directory of internal storage of phone.
   


3. Detach micro USB cable from the phone to make the notification for firmware update poped up on status bar.
   

4. Tap "System Update File Detected..." and follow steps to update firmware.

Note: Steps or photos shown above may have variation by different models.


For some upgraded versions that have great difference, e.g., from Jelly Bean (Android 4.3) to KitKat (Android 4.4),
you may need to upgrade to a "bridge version" in advance to proceed.
Please see picture below for example.
