Can Power Bank Spoil A Phone Battery

 

Yes, power bank can spoil not just your battery but even the charging ic. And these are the cause.

1. Bad quality power bank

Felixamos:
Hello guys, so I went to fix my phone charging port today and the phone repairer advised me against charging constantly with a power bank. According to him, it could spoil a phones battery.. How true is this? Have you had any personal experience?

2. Your Power Bank Has The Wrong Voltage
Having the wrong voltage in your power bank will lead to problems. The ideal voltage to charge a phone is 5V. If any power bank gives a voltage of 4.2V or less, it will drain your battery instead of charging it.

Any voltage output greater than 5V will extensively damage your phone’s circuits by overloading it more than it can handle.

3. You Are Overcharging:
Power banks should essentially be used sparingly. Using power banks to constantly keep your phone at 100% charge will over time damage the battery, which will lead to your phone not being able to retain its charge for long.

To avoid these problems, avoid using your power bank to overcharge your phone. Use it for emergencies, and even when you do use it avoid charging your phone up to 100%.h
