Your mobile power does not last as long as before?
Poor-quality manufacturing or prolonged use can reduce significantly batteries capacity to store energy. Charge the depleted battery with Prufen. If mAh is observed to reduce significantly, then the problem is with the battery. If battery mAh is within specification, then the problem is that there are too many power hungry apps running.
To check the mAh of your Mobile/Tablet, search the web with “Battery capacity mAh xxx” where xxx is your Phone/Tablet model.
