Is it harmful to the battery to play while charging the phone?

We charge mobile phones, sometimes the charging time is short, but sometimes we often forget to unplug the charger. It's like recharging before going to bed at night, and unplugging the charger until you wake up in the morning. If the battery charging time is too long, the charge will exceed the battery's rated capacity. However, some mobile phones generally have an automatic protection mechanism, which automatically disconnects after being fully charged. But it is not ruled out that some inferior chargers and chargers are not equipped with protection circuits. Therefore, it is recommended that you unplug the charger after charging 100%. Mobile phone over-discharge When the battery is too low, there will often be such a situation: because the phone's battery is too low, it automatically shuts down. But after restarting, you will find that the phone still has some remaining power to use (battery power picks up). Automatic shutdown is a protection mechanism for mobile phone batteries by the factory. Over-discharge of the battery leads to a rise in battery power and will cause serious damage to the battery life. Therefore, it is recommended that you add energy to your mobile phone when the battery is below 20%. The temperature is too high. The battery temperature is too high, which will also affect the service life of the mobile phone battery. Frequent use of the battery will discharge and generate heat, which will increase the temperature of the phone. Of course, it is normal for some mobile phones to have a fever, just like Xiaomi phones, which are born for fever. But other mobile phones should control the running time of the program and pay attention to heat dissipation. The temperature is too low When the cell phone battery temperature is below 0 degrees Celsius, it is not allowed to charge the cell phone. Because when the temperature of the mobile phone is too low, charging the mobile phone can easily cause serious damage to the mobile phone. For the life of the mobile phone, try to do this as little as possible. The charger current is too large. Each mobile phone charger has certain parameters such as power, current and voltage. Using high-power charging to charge the mobile phone, there is no doubt that the battery life of the mobile phone will inevitably decrease. Just like roads and cars, there will be problems sooner or later when large trucks cross small roads. In the worst case, it will cause the battery to explode, catch fire, and so on. So it's better to use the original charger with official configuration. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
