Draining Fast and Not charging

I don't know if this will work but you can try it Your phone may have a failing battery, a broken charging stand, a bad charging block, or a background software loop. Since it drained fast and charged slowly on a stand, the issue is likely a weak power supply, a worn battery cell, or optimized charging limits.

Check Your Hardware

Try a cable: Plug the phone directly into a wall charger with a cord instead of using the stand.
Swap the block: Use a different power brick to see if the charging speed improves.
Inspect the port: Clean any lint out of the phone port with a wooden toothpick.
Check Your Software
View battery usage: Open your settings and look at the battery menu to find rogue apps.
Turn off adaptive settings: Disable adaptive charging or battery protection modes that slow down night charging.
Test in safe mode: Reboot your phone in safe mode to see if a hidden app causes fast draining.
