How to charge the phone best for the battery? According to the power adapter manufacturers , there are many mechanisms for the decline of lithium-ion batteries, which can be roughly divided into abuse recession and normal decline. Abuse of recession can be avoided, including overcharge, over discharge, low temperature, high power charge and discharge, and so on. To protect the battery, you should avoid these conditions.

Overcharge: Electronic devices have circuit protection, which is generally not the case, so users do not have to worry. Overdraw: This is a vague concept. In general, try not to use the phone below 20% of the power, especially if you use the phone below 5%, it will cause irreversible damage to the battery.  

Low temperature: mainly refers to the high temperature charging hazard. Electronic devices are generally protected (ipad is not charged at low temperatures), so users do not have to worry. High-power charge and discharge: The discharge of electronic equipment is generally mild. Just keep playing the game, the phone can also support for three or four hours, which is up to 0.2C discharge, very gentle, users do not have to worry. Charging is also protected by the circuitry of the charger and electronics, so users don't have to worry.

Normal decline is unavoidable. The main influencing factors are the integral of the depth of discharge and the state of charge at rest.Depth of charge integration: It can also be called the number of discharge cycles, such as from 100% to 50%, which is 0.5 cycles. This means that the more you use it, the faster the recession. But if the mobile phone is bought, it can be used. ANENPOWER's recommendation is to maintain the mobile phone's power level at 30%-50% low battery level until it is 2 hours before going out and then full to 100%. This is the best battery for your phone.
