Experts tell you: how to activate the new batteries

"The new phone's battery must be charged for more than 8 hours, and repeat several times to fully charge and discharge in order to successfully 'activate' the battery to reach the maximum capacity. Mobile phones and laptop batteries are best used up and recharged to reduce the number of charging and extend battery life. The above "battery protection method" periodically went viral on Weibo and WeChat.

Many experts have confirmed to reporters that these methods can not only fail to protect the battery, but will cause damage to it. The best way to protect your battery is to use it often and recharge it often.

Network spread: the new battery needs to be activated by discharge

The truth: no need for discharge at all

Smart phones are widely used, and it is widely reported on social networking sites that the new phone must be fully charged for 8 hours, then fully discharged, and repeatedly activated several times to fully enable the phone's battery to reach its maximum capacity.

Ou Wu, deputy editor-in-chief of Guokr, handed over a piece of information to reporters which showed that the above approach is completely wrong. Previously, nickel-cadmium rechargeable batteries and nickel-hydride rechargeable batteries did need to be "activated". Today, Li-ion batteries are mostly used, and their initialization is done while the battery is being manufactured. They do not need to be activated through deep charging and discharging. As long as it's a lithium-ion battery, it doesn't need to be activated.

Network spread: the mobile phone battery will explode charging all night

The truth: the legitimate battery can't explode

If the phone is always plugged in to charge even with full power, will the phone battery explode?

According to the data of shell network, lithium ion battery has the possibility of fire and explosion in high voltage, over charge, over discharge, short circuit and high temperature and other cases, there is a possibility of fire and explosion. But this is only a possibility, in the current engineering condition, it's almost impossible. At present, lithium ion batteries are equipped with safety protection devices, which will automatically cut off the battery circuit when over-charging, over-discharging and short-circuit.

Only fake batteries in charge not unplug the power supply in time, is likely to cause the battery explosion.

Network spread: battery run out to refill can prolong life

The truth: it will damage the battery

Each battery can support hundreds of times of charge, all this hundreds of times, the battery will become invalid. The way to extend battery life is to recharge the battery each time it runs out.

Shenzhen rising sun mobile terminal industry institute Yanbiao. Sun said, A charge of 100 percent and then use up 100 percent, this is a cycle life. Using 10% once and then charging 10% again for 10 cycles is also considered a cycle life.

Batteries like the human body, he told reporters, "fixed" is not healthy for a long time. Long periods of "disuse" after charging and long periods of plugged in power cords are not healthy, and battery capacity is irreversibly reduced." The healthiest thing to do is to exercise your batteries regularly: use it whenever you have a chance. Plug in a power cord and charge it up when you're almost done."

Network spread: Playing games while charging damages the battery

The truth: high temperature does damage the battery

Is it true that playing games while charging your phone can harm your phone's battery?

Electrical engineer Guobin.Cao said, "high temperature" does have an impact on the battery. Under the condition of high temperature, the battery capacity will decrease irreversibly. If the phone in the sun insolates, great damage to the battery life. On the contrary, if big put battery in air conditioning room to blow air conditioning in summer, do benefit the battery health.

Is playing games while charging your phone harmful to your battery? Guobin.Cao said, In fact, when charging USB power is divided into two ways after entering the phone, one way to charge the battery, the other way to support the phone module such as the display screen power supply. If playing mobile phone game very intense, cell phone chips heat up at high temperature, will indeed damage the health of the battery.
