How to fix an Android phone that doesn't charge or discharges when connected to a power source

It could be really confusing to see the charging sign on your phone when connected to your charger only for your battery percentage to remain at the same level for hours or in fact drop steadily. If you’re a heavy user then you must have encountered this on one or two occasions (see https://journal.hovatek.com/how-to-fix-an-android-phone-that-automatically-goes-off-or-shuts-down-frequently/ ) but that isn’t to say that light users are exempted from this puzzling phenomenon.

Lets look at it from a less-techy perspective for a moment. If you connect your charger (which is supposed to increase battery levels) but the battery levels are dropping instead, then it must either mean that the phone isn’t being charged at all or the battery is being consumed faster than its being charged. Now that we’ve established this, lets proceed.

Why is my Android phone discharging despite being connected to a power source?

Common causes of this issue are:

  • Faulty power source: If you’re charging using a PC (via USB cord) or from a faulty power source then this is possible
  • Faulty USB port: A loose, cracked or broken phone USB port could be a cause
  • Faulty charger: If the charger is faulty or not powerful enough then you can expect something like this
  • Buggy ROM: If you flashed a custom ROM / Firmware upgrade with power efficiency bugs then you have another possible culprit
  • Heavy usage during charging: If you’re running processor / battery intensive processes during charging then you have another possible cause
  • Faulty battery: Some batteries have problems retaining charge after extensive use

      You mean while on, the battery level remains constant or even drops while charging?

    infinix zero, when ever i plug it in, it’ll show sign of charging but go off immediately. Holding the volume increase button makes the screen flash light and go off again.

          connect the phone to a PC with battery inside. Does it keep making the connection-disconnection sound?

            The battery is most likely drained. You’ll need to boost it

    Good day
    My tecno y4 suddenly stopped powering on. It shows ”experience smart life” and remains that way.
    Also, it shows a lightning bolt in the battery when the charger is connected.
    I have changed battery and charger but i still have the same issue.
    The rom of the phone is the one dat came wit the phone.

    Please, come to my rescue.
