Why You Should Replace Your Phone Battery?

With your mobile phone facing daily use (likely for hours on end), your battery will start to deteriorate leaving you in a constant state of charging your phone. This is entirely natural with batteries but can have a huge impact on the performance of your smartphone the longer you allow it to deteriorate. Replacing your phone battery can return your device to its previous quality and ensure you get the very best performance out of your smartphone as you can.

When Should you Replace your Battery?

The biggest indication of when you need to replace the battery is, fairly evident, the battery life. If your phone used to last all day on a single charge but is now struggling to make it to lunchtime, then you are likely having serious battery issues. Replacing your old battery with a fresh one is the only way to counteract this.

There are several other factors that an old battery can affect that you may have not previously considered. Some of the warning signs you should look out for are:

  • Screen Glitches
  • Slow Performance
  • Phone shutting down or rebooting automatically
  • Crashing applications
  • Phone overheating easily

Will Replacing my Battery Void my Warranty?

This depends on the manufacturer of your device but usually, it will not void a warranty. However, if you have had your phone long enough where your battery starts to deteriorate, your warranty would likely have already expired.
