Sir my model is asus zenfone max m1 (not pro) and my problem is some times I am using mobile and my battery percentage is 78% and suddenly it falls to 76% and then it is normal and this problem happens after some times like this falling 2% battery
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.
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.
