1. Before leaving the factory, the battery is activated and pre-charged, so the battery has some residual power. Some people say that the battery still has insufficient standby time even after charging according to the adjustment period. Assuming that the battery is indeed a genuine battery, in this case, the adjustment period should be extended and 3 to 5 full charge and discharge cycles should be performed.
2. If the newly purchased mobile phone battery is lithium-ion, the first 3-5 charges are generally called the adjustment period, and should be charged for more than 14 hours to ensure full activation of the lithium ions. Lithium-ion batteries do not have a memory effect, but they have strong inertia. They should be fully activated to ensure optimal performance in future use.
3. Some automated smart fast chargers only indicate a 90% charge when the indicator light changes. The charger will automatically switch to a slower charging speed to fully charge the battery. It is best to use the battery after it is fully charged; otherwise, the battery life will be shortened.
4. Do not intentionally discharge lithium-ion batteries before charging, as improper discharge can damage the battery. When charging, use slow charging as much as possible and reduce fast charging time; do not exceed 24 hours. The internal chemical substances of the battery will be fully activated and achieve optimal performance after three to five complete charge-discharge cycles.
5. Please use original or reputable brand chargers. Lithium-ion batteries must be charged with a dedicated lithium-ion battery charger and the instructions must be followed. Otherwise, the battery may be damaged or even dangerous.
6. Many users often leave their phones on while charging, which can easily damage the phone's lifespan. During charging, the phone's circuit board heats up, and if there is an incoming call at this time, there may be a momentary backflow current, which can damage the internal components of the phone.
7. Battery lifespan depends on the number of charge-discharge cycles, so you should avoid charging the battery when it still has residual power, as this will shorten its lifespan. If your phone has been turned off for more than 7 days, you should fully discharge the battery and then fully charge it before using it again.
