When your phone’s battery loses while charging, it indicates that your battery is dead, your phone is draining faster than it is charging, or your charger is not giving out enough voltage or ampere rate for efficient charging. 

So, in this case, what you can do is check out those mentioned tips and find out what really is going on in your phone’s battery. 

In this article we deeply discuss the battery losing problem while charging. So stick around until the end to find out what you’ve been looking for. Welcome to Battery Principles. 

What causes the phone battery to drain while charging?

As we’ve mentioned above, there can be many reasons for this problem. So there is a checklist that you need to check out before you send the phone to a repair shop. 

• Confirm you are using the original charger. 

If you are not using the original charger that came with the phone, it affects your battery badly because the output voltage and the ampere rate are not at their best matching states.

So the best thing is to use the original charger as long as you can, and if the charger is damaged, do not go for cheaper low quality solutions.

• Confirm no app is draining the battery. 

As we’ve discussed in our articles on this blog, there are tons of applications that drain your battery faster. So when the battery is dying while charging, check out those applications and remove them to find out what really happens inside. 

• Ensure the charging port is not loose. 

The charging port on your phone may corrode if it is exposed to moisture or is kept in a humid environment. The contacts will become blocked by dirt, debris, and dust, which will stop the port from functioning properly.

Depending on the model and whether you purchase a standalone charging port or a flex cable/assembly, you should budget between $2 and $30 for a new charging port.

• Confirm the battery is well connected.

This is only applicable when your phone’s battery is removable. So if your battery is removable, then take the battery out and check the connections. If the pins are corroded or the shine has been reduced, then clean the pins and set the battery again. 

So when you have confirmed that there is nothing wrong with it, then you have to bring the phone to a repair shop to replace the battery, because when the battery is dead or when the health is very low, then the battery cannot be repaired and all you can do is replace the battery.

Is it okay to use phone while charging?

Your smartphone can be used while charging, yes. Using your phone while it is charging carries no risk. In order to provide enough power for continuous use, the battery charges more slowly when your phone is in use while it is being charged.
