How to charge smart phones is the best way to charge smart phones!
Sihai network: when mobile phones enter the era of smart phones, many people still keep the traditional charging methods of mobile phones. For example, the first time a new mobile phone is charged, it must be full for 12 hours, and it can only be charged when the power is used up. In fact, these are all wrong methods. Let's see what are the mistakes in charging smart phones!
1. The new battery needs to be fully charged for 12 hours?
The first charge doesn't need to be full for 12 hours, which is what old-fashioned NiMH batteries need to do. The batteries used in smart phones and laptops are mostly lithium-ion batteries or polymer lithium batteries. For the first time, just like normal charging, the battery full indicator light is on.
2. Can reducing the charging times prolong the battery life?
Lithium battery has no memory effect and can be charged at any time. In order to reduce the number of charges, the battery is deliberately used up and refilled, which does not extend the battery life, but has a negative impact on the battery life. In fact, lithium battery charging pays attention to "eat less and eat more". Frequent shallow charging and discharging is more helpful to prolong its service life.
3. When charging, the battery will explode?
Lithium battery generally has safety protection circuit and various safety devices to ensure that the circuit of battery will be cut off automatically in case of overcharge, discharge and short circuit. Therefore, unless there is a quality problem, the battery will not explode due to long-term charging.
But from a safety point of view, when charging, do not cover anything on the battery or put it on the bed to avoid fire. In addition, try not to answer the phone when charging, because the electromagnetic radiation of the mobile phone during charging will be relatively large.
4. Recharge after the battery is used up?
Try to use up the battery power of mobile phone, and it is better to use automatic shutdown. This method is only applicable to nickel battery, so as to avoid memory effect. Now most of the mobile phones in the market use lithium batteries. The number of rechargeable batteries is closely related to the depth of battery discharge. When the lithium battery is in low power consumption, the loss is relatively large, so when the power consumption is exhausted, recharging will accelerate its loss. The battery can last for a long time at 40% ~ 60% power.
5. Will overnight charging damage the mobile phone?
When the mobile phone is not unplugged after charging, the mobile phone is powered directly through the power supply, which reduces the charging times of the battery and helps to extend the battery life. However, if you always play games on the power supply, the phone may overheat due to the high heat generated by the power supply, which will have an impact on the battery, so as long as the phone is not overheated, the overnight charging will not damage the battery.
6. The mobile phone does not need to be shut down or restarted
Should the phone be turned off like a computer? Apple recommends that users turn off the phone once a week to extend battery life.
