Symptoms of a Weak Battery on an Android Device

Here are some symptoms to look for to identify whether your phone battery health is dying:

  • Phone isn’t turning on: If your phone doesn’t even power on, it means that its battery is completely out of juice. It’s hard for a battery to charge again once it loses all charge.
  • Works only when plugged in: If your phone only turns on when it’s plugged in and immediately turns off as soon as it’s plugged out of the charger, this also means that your phone’s battery is dead.
  • Battery heats up: If your phone battery heats up above 90 F, it also indicates that your battery doesn’t have great health. 
  • Swollen battery: Overcharging your phone can sometimes result in a swollen battery, which is a major sign of an unhealthy battery. Plus, using a phone with a swollen battery is dangerous as it can explode anytime.
  • Battery doesn’t last: If your phone’s battery fails to last even 8 hours after full charge, your battery health is extremely poor.

Tips and Tricks to Make Your Phone Battery Last Longer

If your phone’s battery health is declining and you want it to last longer, here are some tips that might help.

  • If you cannot charge your phone and want your battery to last a little longer so you can use it in an emergency, a great way to do this is by turning off your Bluetooth and WiFi.
  • Stop the background usage of apps that are consuming the most power.
  • Never charge your phone more than 99%, as overcharging can damage battery health.
  • Don’t charge your phone with the charger of other devices. Always use the original charger because it is made for the voltage of your phone’s battery. 
  • Reduce the brightness of your phone’s display and reduce the timer for its auto lock screen. 
  • Phone batteries’ charge level drops faster if placed in a hot atmosphere. Therefore, you need to keep your phone somewhere cool, especially while charging, to make it last longer.
  • Most phones nowadays also come with battery saver modes. If your phone has one, you can also turn it on to save battery.
  • Vibration utilizes more battery than a ringtone. Thus if your phone is on vibration, you need to turn it off.
  • Location services are also battery drainers, so you should only turn them on using Google Maps or other location-based apps.
