At present, when smart phones are not talking, the highest power consumption is the display screen, especially the large-screen mobile phone; The current charger is generally less than 1A charging current, generally between 200 and 500, generally in accordance with the 3-stage charging, that is, fast charge - slow charge - trickle.
Therefore, when the screen is bright, most of the current is to maintain the display, and the current charged to the battery is very small; The time is longer.
Solutions: 1, try not to; Try not to use the phone while charging, keep the screen black; 2.
If you must use the screen, you can only turn down the brightness of the screen and see it clearly.
3, change the current of the charger, generally with a charging bank and other mobile power supply current is relatively large, charging time is very short. However, the battery is generally not charged, generally to 80%. It's not great for the battery either.
Hope I can help you.
