It will have an impact.
Because during the charging process of the battery, the current flows to the inside of the battery, the chemical reaction inside the battery will occur, resulting in electrochemical changes in the positive and negative electrode materials and internal resistance changes.
If the fast charge mode is frequently used or overcharged, the internal temperature of the battery will rise too fast, which will damage the life and performance of the battery. In addition, mastering the correct charging method and charging time, as well as choosing the right charger can also effectively extend the service life and stability of the battery.
If the user can correctly operate the charging bank, mobile phone battery, etc., for reasonable management and maintenance, to ensure its long-term stability and performance.
nothing influential
Yes, the phone battery left 50% charge, it will not affect the battery. In many people's concept, the battery will be better to use less than 20% before charging, and this is true in the era of nickel batteries. But to the current era of lithium batteries, really let the phone power down to 20% or even automatic shutdown, the damage to the battery is very large, will cause slow charging, battery is not used, and even battery life is reduced.
In addition, if the phone is used to automatically shut down, the lithium battery will be too low due to excessive discharge, which may not be able to start and charge.
No impact, the current battery is generally lithium batteries or lead-acid batteries, and there is no impact memory effect.
Nickel-cadmium batteries have a charge memory effect, but these batteries are now rarely used.
Just bought a mobile phone, the first charge to 50%, in fact, there is no impact, because the current battery is different from the previous battery process, most of the batteries are lithium batteries, do not need to be fully full for the first time, but should not often let the phone keep in a state of insufficient power, the damage to the battery is more serious, try to use more charge, Keep your phone's battery level at a certain limit
It doesn't matter. Lithium battery charge and discharge is a number of times. I'll give you a charge when you're done. This has no effect on the battery. On the contrary, the battery life can be extended.
