By: Editorial Team

Theirs is nothing more frustrating than plugging in your smartphone. And find out that instead of charging the battery discharges slowly.

Here’s why your iPhone or android smartphone discharging while charging. And what you can do to solve the problem.

How Does Charging and Discharging Work?

A battery has a cathode, anode and an electrolyte. Cathodes are denoted by the positive (+) sign, anodes are denoted by the minus (-) sign and the electrolytes are the substance or material between them.

Electrolytes help the ions not electrons in batteries to move from the anode to the cathode and vice versa.

There are several types of batteries out there. But, lithium-ion batteries are the ones used in smartphones.

And your smartphone charger is a switch or cable that completes the circuit. Once the circuit is completed charging happens.

Chemical reactions start to take place when you connect your smartphone to a power source. Electrons then start to move from where they are a lot to where they are less.

In this case, they move from the cathode (+) to the anode (-) when the battery is being charged.

Once the battery is fully charged, it sends a signal to the charger and shuts off the power delivery.

Or it might be that you disconnect your smartphone once it reaches your desired power level. Stopping the charging process.

Once the charging process has ended. The electrons start to flow from the negative side (anode) to the positive side (cathode). This movement is what supplies power to your smartphone device.

Once all the electrons have gone over to the cathode. Your battery runs out of power and requires a recharge.

Why Is My Phone Charger Draining My Battery?

Faulty Charger or Charging Port

Another culprit might be your charger or charging port. Check your charger if they are faults. Don’t forget to check the USB cable. It might be damaged.

If there are no faults then it might be that your charger’s voltage is not enough to supply the battery with power. This makes the battery discharge occur even when plugged in.

Your USB charging port might also be faulty interrupting power supply. A faulty USB charger port might prevent full contact with the USB cable.

Heavy Usage Whiles Charging

Smartphones are like mini-computers and so they consume a lot of power. Using your smartphone heavily whiles charging is definitely going to cause the battery to discharge.
