The health of mobile phone battery refers to the ratio between its capacity and the initial design capacity.Generally, the health of newly purchased mobile phone batteries should be close to 100%.With the increase of time and use times, the health of the battery will gradually decline.
Generally speaking, when the health of mobile phone battery is less than 80%, it can be considered that it has begun to decline.When the health degree reaches below 70%, there may be obvious problems such as shortened endurance.In this case, the user may need to consider replacing the battery or replacing the mobile phone.
However, not everyone will strictly follow this standard.For users who use mobile phone functions slightly and pay little attention to the endurance, they may not feel a significant impact after their health is less than 80%.
To keep the cell phone battery healthy, there are some precautions to follow: avoid excessive charging and discharging as far as possible, avoid high temperature environment, conduct complete charging and discharging regularly to balance the pressure between cells, select regular brands and original accessories, etc
To sum up, cell phone batteries between 90% and 100% are considered normal;80% - 90% means it is still good;Between 70% and 80%, pay attention to the battery life;Below 70%, it may cause some inconvenience to the use of mobile phones.However, this is only a rough reference range, and it cannot completely and accurately measure everyone's use needs and habits.
80% of the batteries are healthy and do not need to be replaced. Determine whether the battery needs to be replaced: 1. From the perspective of standby time, if a mobile phone can be used normally for 20 hours after being fully charged after the initial purchase, and can only be used for 10 hours after being fully charged for a period of time, it indicates that the mobile phone battery is aging.In addition to the short standby time, if the power of the phone drops suddenly during normal use, it also proves that the battery has aged. 2. The most professional way to detect whether the battery is aging is to rely on professional software.Android phones can be used by Jinshan Battery Doctor or Battery Manager and other software.Check the fully charged capacity first, and then compare it with the standard capacity of the battery.
Maintenance skills of mobile phone battery: 1. Never charge the mobile phone to 100% before powering off, so that it can be charged continuously after 100%.The full charge form of the battery will create pressure on the battery itself, and the abnormal low battery of the mobile phone will also cause abnormal damage to the mobile phone battery. 2. To prevent the battery from charging at too high temperature, this is to inform everyone not to charge while playing with the phone, because the temperature of the phone will become very high when the CPU has a fever, and charging in this form will cause serious damage to the battery.
1. The battery is excessively worn and has been completely damaged
Generally speaking, this kind of situation is rare. You can check the battery health through our education.The battery health of an iPhone in normal use is above 85% within one year and above 75% within two years.But if you use it for one year and it has dropped by 80%, there are only two possibilities. One is that you have bought a fake, and the other is that you often commit the battery damage behavior mentioned in the previous chapter.I have seen people who charge their batteries several times a day because they play card games, but the battery health of their mobile phones has dropped to 78% in less than half a year.
2. Battery management IC is damaged
This is mostly due to the mobile phone falling on the ground, which leads to the main board component desoldering. The probability is very small.If the battery cannot be charged and the main board is damaged, the store will charge you more than 500 so-called fees for replacing the main board. In fact, it only needs more than 100 power supply ICs to be replaced.
3. Non original charger, charging line damaged
This is easy. Ask someone for an original iPhone charger and charging cable.
4. Mobile phone system failure
Press the power button+Home button at the same time until the Apple logo appears, and force the iPhone to restart. This should solve the problem.
5. The gold finger of the charging port is oxidized or dirty
Scratch the golden finger of the charging port on the iPhone with the Sim card pin provided with the iPhone, and try to scrape off some oxide on it (generally, this problem occurs on an old iPhone that has been used for more than 1-2 years). If the iPhone is charged when the lightning port is wet, the pins on the lightning port or cable will be corroded, causing permanent damage or failure to work, resulting in connection problems with iPhone or accessories. If this prompt appears, you can do this: 1. Unplug all cables or accessories.Do not insert them until they are completely dry. 2. Turn the lightning connector down and tap the iPhone gently with your hand to drain the rest of the liquid.Place iPhone in a ventilated, dry area. 3. Wait at least 30 minutes before attempting to charge with a lightning cable or connect lightning accessories. If you see the reminder again, there is still liquid in the lightning port or under the pin of the lightning cable.Please leave iPhone in a ventilated and dry area for one day.In the meantime, you can try charging iPhone or connecting lightning accessories again.It may take up to 24 hours for complete drying. 4. If you have a wireless charger, you can still use it to charge iPhone.
