Can the phone be fully charged when it is used up?

For those who continue to charge after filling, I believe many of my friends will meet in daily life. Many friends have to charge the mobile phone before going to bed, and then pull out the data cable the next day, which will result in charging the mobile phone every time. There are several hours of trickle charging. So, the question is, after the phone is fully charged, if it continues to charge, will it cause problems with the phone? Before that, let us first introduce whether there is a need for trickle charging after the phone is fully charged.

First of all, it is recommended to have time to rush.

Most mobile phones now use lithium batteries, which no longer need to be fully discharged and filled, and the first time does not take more than 12 hours. Multiple plugging and unplugging the power supply will not affect the battery, so in actual use, as long as there is power, the phone can be charged at any time.

Second, when is the fastest?

In terms of efficiency, the general mobile phone has the fastest charging efficiency when 15%-20% of the battery is left. Therefore, it is not recommended to charge when the phone is running low because the phone will receive too much current. Of course, it is not recommended to charge when the power is higher than 50%, because this will not only make the charging efficiency low, but also cause the voltage to rise to 2 times and the battery is lost.

So we see that mobile phones on the market will remind you to charge when the power is 20% (different brands are different), and at 10%, the phone will have a red warning that the battery is too low. In other words, when the phone's power is less than 20%, it starts to hungry, and we should feed it.

Finally, don't continue to charge after full power.

Today's lithium batteries do not need to be fully charged and then powered down. If the phone is fully charged but connected to the power supply, it will affect the battery life. Because the phone is fully charged, it will continue to charge in "Trickle Charge" mode to maintain full battery status. If you continue to charge, the battery of the mobile phone will be affected by the current, and some chemical components will be destroyed, which will affect the efficiency of use.

Remind that after the phone is fully charged, the voltage inside the battery will rise, increasing the battery load. A mobile phone lithium battery may instantaneously discharge a large amount of current under special conditions of temperature, humidity and poor contact, causing spontaneous combustion or explosion, and overcharging is one of the causes of such problems.

Warning: Of course, at some time, if the battery is really unbearable, it will lead to incomplete data reception and serious data loss, but don't worry that we can use the Apple Recovery Wizard to recover some data that was accidentally deleted in the iPhone. It is safer to use the Mobile Data Recovery Wizard to restore lost data.
