In today’s time, the battery of the smartphone ends quickly and people resort to the power bank to use the phone throughout the day. But many people do not know that keeping the power bank cable in the phone for hours can be harmful for both the phone and your health. If you too are negligent during charging from the power bank, then be careful.

1. Impact on phone battery due to overcharging
Charging the phone for a long time from the power bank is at risk of overcharging. Although modern smartphones have an auto cut feature, but not all power banks have this technology. Due to this, the performance of the battery gradually starts to weaken and the phone starts discharging quickly.

2. Heating problem
When you keep the phone connected to the power bank for hours, there is a constant pressure on the battery, which can make both the phone and the power bank warm. This can damage the motherboard or charging circuit of the phone.

3. Threat of blast
Low quality or long use of local power bank can cause blasts. Many times after overheating and full charge, the cable can cause a short circuit, which can cause a phone or power bank to burst.

4. Charging in sleep is most dangerous
Some people sleep overnight and sleep with the power bank. This habit can also be harmful for health, as electromagnetic radiation can affect your brain. Also, the risk of explosion in the battery also increases.

5. Repeatedly charging with power bank reduces battery life
On repeated charging from the power bank, the charging cycle of the phone’s battery is completed quickly, which reduces its age.
