How to Replace the Battery in your Smartphone?

If you have the same smartphone for two years now, it must have deteriorated your battery. Your smartphone is not running the same amount of time it used to, indicating a drained battery. The number of charge cycles determines the lifespan of smartphone batteries. It means that when you fully charge your smartphone's battery and then drain it, it's one charge cycle. Some other phone manufacturers define this cycle to be only half drained and then put to charge again. Most lithium-ion batteries are effective up to 500 charge cycles. Then they go downhill at a rapid rate. The same battery, when new, used to run for 24 hours straight, now lasts only 6 hours. Yes, that is very common in smartphones. Now before we move on to the battery replacement guide, let's look at the signs you need to replace the battery.

Signs You Need To Replace The Battery In Your Smartphone

·        Reduced Battery Life

The most obvious sign is the battery timing itself. If you have noticed your phone's full battery runs out of charge very quickly now, it's time to retire that old battery.

·        Random Boot Loops

A reboot loop or boot loop is when your phone restarts on its own randomly. It's totally fine when a new update is being installed. Other than that, if your phone goes on a reboot frenzy, there is a serious issue with its battery.

·        Reboot at a Certain Threshold

If your phone reboots suddenly after reaching a certain battery threshold, it is also a sign that you need to replace the battery. For instance, if the phone restarts on its own whenever it drops to 30% battery, the battery needs to be replaced. These were a few signs, but if you want to be really sure, you can contact a cell phone repair company. At this stage, it is also important to check the health of your battery.

Check the Battery's Health

The easiest way to check the battery's health on an android or iOS phone is

  • Go to Settings
  • Go down and select Battery
  • Tap Battery health

Once in there, you can view all the essential stats of your phone's battery. For a smartphone that doesn't have any battery health viewing feature, you can install separate apps to check battery health.

Replacing The Battery In Your Smartphone

Finally, here is a simple way to replace the battery in your smartphone. If you are doing it on your own, make sure you own a phone that has a removable battery.

  • Save all your documents on the phone if you use them for work.
  • Close all the running apps
  • Turn off the phone
  • Carefully remove the back cover of the phone
  • Replace the battery with a new one

In case you have a phone with a non-removable battery, you will need to approach a professional cell phone service company. Trying to replace the battery in a non-removable battery phone on your own is risky and can damage the phone.


When it comes to replacing the parts of your smartphone, always consult a professional. Battery replacement by a professional smartphone repair company is far better than trying all the DIY methods. The proper adhesive in these devices prevents the user from making any such changes to the phone's hardware. Tampering that adhesive can damage the phone completely.
