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. Replacing your phone battery can return your device to its previous quality and ensure you get the very best performance out of your smartphone.

When Should you Replace your Battery?

The battery life is the biggest indication of when you need to replace the battery. 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

After around 2/3 years, you will likely start to notice a few of these happening to your phone. This is a fairly natural part of a phone’s lifespan as lithium batteries cannot last forever.

You can check the health of your battery on your iPhone in the settings, look for “Battery” and then “Battery Health”. Apple recommends replacing the battery when the percentage goes under 80%.

On Android, you can see how long a full charge will last through the settings. Go to “Battery” then “Battery Usage”. You won’t get a solid number of how your battery’s health is, but you can get a good idea.

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 that your battery starts to deteriorate, your warranty would likely have already expired.

Make sure to check with your specific manufacturer for their warranty and battery replacement rules.

Do I Need To Backup My Phone Before Getting A New Battery?

You should always back up any saved data on your phone before any repair. Getting a replacement battery does not involve any of your personal data and therefore shouldn’t effect anything you have saved on your phone.

As with any repair, there are some rare times it goes wrong, this is why we fully recommend backing up your phone, just to be safe.
