When an Android phone is in use, the system automatically records battery power information. After the phone battery has been used for a period of time, due to irregular use (such as unplugging the phone before it is fully charged), the battery information recorded by the phone system will gradually become inaccurate or incomplete, which can easily lead to recording errors. As a result, even though the battery still has power, the system may default to running out of power and automatically shut down the phone.
So, how can we get the system to re-record complete battery information, calibrate the battery, and restore it to optimal performance?
1. With the phone powered on normally, fully charge it and then unplug it;
2. Then turn off the phone, plug it in to charge until it is fully charged, and then unplug the power cord.
3. Power on the phone, and once it has fully booted into the system, immediately power it off again.
4. Now connect the charger and wait for a while until the phone is fully charged;
5. After that, unplug the power cord, and you can turn it on and use it normally.
How to maintain your mobile phone battery
1. Before leaving the factory, the manufacturer activates and pre-charges the batteries, so they all have some residual power. Some people say that even after charging the batteries according to the adjustment period, the standby time is still seriously insufficient. Assuming that the batteries are genuine, in this case, the adjustment period should be extended and 3 to 5 more 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 that the lithium ions are fully activated. Lithium-ion batteries do not have a memory effect, but they have strong inertia. They should be fully activated to ensure that they can achieve optimal performance in future use.
3. Some chargers only indicate a 90% charge when the indicator light changes. The charger will automatically switch to slow charging to fully charge the battery. It is best to use the battery after it is fully charged, otherwise the usage time will be shortened.
4. Lithium batteries do not need to be specifically discharged before charging; improper discharge can damage the battery. When charging, use slow charging as much as possible and reduce fast charging; the charging time should not exceed 24 hours. The internal chemical substances of the battery will only be fully "activated" and achieve optimal performance after three to five complete charge-discharge cycles.
5. Please use original or reputable brand chargers. Lithium batteries must be charged with lithium battery-specific chargers 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, it may generate 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 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.
8. All mobile phone batteries have self-discharge. When not in use, nickel-metal hydride batteries will discharge about 1% of their remaining capacity per day, while lithium batteries will discharge about 0.2% to 0.3% per day. When charging the battery, try to use a dedicated socket and do not share a socket with other household appliances such as televisions.
9. Do not expose the battery to high or low temperatures. For example, during the hottest days of summer, do not leave your phone in a car exposed to direct sunlight, or in an air-conditioned room where it is directly exposed to cold air. It is normal for the battery to get a little warm while charging, but it should not be subjected to extreme heat. To avoid this, it is best to charge at room temperature and not cover the phone with anything.
10. Lithium-ion batteries must be charged with a dedicated charger; otherwise, they may not reach full charge, affecting their performance. After charging is complete, avoid leaving the battery on the charger for more than 12 hours. When not in use for an extended period, the battery should be separated from the phone.
