Nokia6500C should be turned on or off when charging?

Of course, it's good to shut down. Because the boot will have current and is unstable, there will be the problem of burning the phone or battery, which can avoid electromagnetic radiation to the greatest extent.

During travel, or for fear of delay**, many friends will use the travel charger to charge their mobile phones when they run out of power. When charging in the power-on state, there are no adverse effects as long as the phone is not operated. However, if you make and receive calls**, send text messages, surf the Internet**, ringtones, MMS, and play games, it will cause harm to mobile phones, people, and batteries.

There are three reasons: First of all, the voltage of the mobile phone when charging is higher than that when it is standby, if you make a call at the same time, the voltage will exceed the usual many times at the moment of calling or connecting to the network, which is easy to damage the sensitive parts inside the mobile phone. Secondly, when using a mobile phone while the mobile phone is charging, the radiation dose is dozens of times that of usual, and the damage to the human body is self-evident.

Third, since the battery life is calculated according to the charging and discharging cycle, the number of charging directly affects the battery life of the mobile phone. If the power supply is plugged and unplugged many times during charging, the battery life will be reduced due to repeated discharge. Therefore, when the mobile phone is powered on and uses the travel charger, it must not be called**.

If there is an important callback, it is recommended to use a different callback. As a last resort, you should also unplug the charging power supply and connect it again.

There are two ways to think about it:

1.For mobile phones, charging off is definitely better than charging at power.

2.It's better for you to charge it on than to charge it off, so you don't miss ** or text messages.

1.Is there a charging display when charging with direct charging? If not, it is possible that the battery is dormant, and the battery needs to be activated with a cradle charger or universal charger.

2.If you confirm that the battery is sufficient, it still can't be turned on, you can try to put the phone on hard.
