My Asus phone's battery used to last 2 days easily, but from the past 6 months or so the phone drains very quickly. The phone barelt gives a one day battery with around only 2 hours of screen time. Asus please help me rectify this issue. I am hopeless now, I think even iPhone see with half the battery size of this phone gives more sot than asus zf max pro m2.

Hi, when you say that your SOT (Screen on Time) has gone down, can you share the SOT after trying the below:
1. Charge the battery to 100% & use as per your normal usage pattern
2. When the battery strength reaches 10%, go to settings = Battery => Tap on the battery icon & share the graph
3. settings => Battery => Check the screen & share the same

Also, 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. 
5. Check the following article for more information: https://www.asus.com/in/support/article/604/
