    Having the extact same issue.. Phone mysteriously goes into battery draining mode then disappears. When i do manage to catch the app causing the issue.. Guess what it's "googles framework".. Followed all of the tweaking steps. Removed all software that doesn't get used. Disabled all functions the same way. Turned off all auto start. Have memory in super clean mode, etc. I even crippled the phones ability to use location services, cell phone carrier location. The phone starts to overheat then it starts draining the battery, checked the battery meter and it shows like 4hrs remaining form a 96% battery and all power functions are reading normal in the Battery meter. I have restart the phone before it drains the battery to nothing. I have 4 business apps running, that 's it, very disappointed and now with the super mem clean function i get no notifications for e-mail, teams, etc..

  • @Ahsaan As a first step, charge your phone to 100% and put it in flight mode before going to bed. It should only drain a couple of percent during the night. If that's the case, it's possible you have an app chugging data in the background and draining battery.

  • Hey, Asus Family ther's a good news for you guys, I think I've found the solution for your queries!

    Now, Jot down what I say on a paper & follow them as I did(Read until the end):

    Part 1 ( You can skip this if you're a geek)

    -Turn off unwanted services like location, bluetooth, network(Wi-fi,Mobile Data) until you really need them. Keep an eye on these services.

    -Turn off notifications and restrict background data usage from app settings of unwanted and not so important apps for you like games, FB, Insta etc...You really don't need them I guess.

    -Turn off auto-brightness and set brightness according to your surroundings manually. Lower brightness will give you even more battery.

    -Set low display sleep time like upto 1 minute or 2 minute if you really need it!

    -Turn off haptic feedback, touch to vibrate/tones on keyboard and others. Turn off lock and unlock sounds. Turn off touch sounds. I think you really don't need them. Turn off all unwanted sounds from sound settings.

    -Keep your homescreens as simple as possible and fill em'up only with your most frquent apps and widgets...don't try to get all the widgets up and running for you always on the homescreen.

    Part 2 ( Mandatory for every user, even non-Asus, Sorry only for Asus, this is Zentalk right!🤣)

    Here are even more important things to save battery:

    -Turn off 'Hey Google' or 'Ok Google' from 'VoiceMatch' settings because you don't need the mic always running for you.

    -Don't use a battery saver until you really need them(You'll only need it if battery is low). Battery saver reduces clock speed and I know many people use battery saver to do cpu and gpu heavy tasks with Battery Saver On, This increases strain on cpu and gpu and they run for a longer time for the same process without battery saver...This will drain your battery drastically. You can use battery saver only when your battery is low like 25-30% or can always use it if you don't perform heavy tasks on battery saver mode, it mostly only used for calls, texting messages, slight surfing and other basic but important things because you probably don't have your charger around all the time!

    -Try to switch off unwanted gestures like all ' Zenmotion' gestures from 'System' in Settings and 'Smart Screen On' in Display settings etc... Until you really really need them!

    - After every Software/FOTA update from Asus 'wipe out the cache partition' from bootloader menu( Swith off your phone and Hold down Power+Volume down button until you see the Asus logo ,, now navigate using the Volume buttons and select using the power buttons)

    -Last but not the least, Recalibrate your battery( Surf the web to find out how to Recalibrate


    If still you are facing battery issues, then it's time to get a new battery! Or even a new device.
