According to Apple's official regulations, the health of iPhone is above 80% within 1 year after purchase. Because the warranty of Apple's mobile phone is 1 year, if you don't buy AppleCare+ separately, in theory, this mobile phone has nothing to do with Apple after being used for 1 year. If there is any fault, you need to pay extra for official after-sales maintenance.
The lithium polymer battery of smart phone has a long service life. Under normal circumstances, the capacity of a mobile phone will drop to about 70% after more than 500 charge and discharge cycles. In this case, the battery life of the mobile phone will be obviously insufficient. However, 500 charging and discharging cycles does not mean 500 charging, but the whole process of mobile phone power from 0 to 100% and then to 0.
Under normal circumstances, it usually takes 2 days for an Apple mobile phone to complete a complete charge and discharge cycle. 500 cycles is enough for iPhone to use 1000 days, which means that the battery capacity of iPhone will be reduced to about 70% after normal use for about 2 years and 7 months.
So the battery capacity of iPhone 1 1 dropped by 6% in one month. According to this progress, 10 will use up 60% in a month, which is obviously abnormal.
However, the loss of lithium polymer battery is not linear. It may decrease by 6% in the first month, but it will remain at 94% in the second month. Therefore, it is better to observe more when encountering the phenomenon that new mobile phones consume too fast. If it falls below 80% within 1 year, it may be the quality problem of the battery. You can go to Apple and ask for a new battery for free after sale.
In addition, the loss and fast charging of Apple's mobile phone have little to do with overnight charging. Because iPhone 1 1 itself supports fast charge function, this function has been repeatedly tested by Apple, and normal use of fast charge will not lead to rapid battery decay. Similarly, there is a charging protection chip in the iPhone. When the phone detects that the battery is full, it will stop charging the battery.
Therefore, under normal circumstances, even if the battery is charged overnight every day, it will not lead to rapid battery decay. However, the bad habits of some netizens will also lead to battery wear.
For example, charging while playing games, in this case, there will be high heat inside the mobile phone, which will cause the chemicals inside the battery to fall off from the positive and negative electrodes, thus shortening the battery life. In addition, every time you use your mobile phone, it will be dead until it is automatically turned off, which will also seriously affect the life of the battery.
Pay more attention to the following aspects in daily use to reduce the loss of battery health of Apple mobile phones.
First, try not to let the mobile phone be in a state of low battery power, which is conducive to alleviating the rapid decline of battery health. Nowadays, all mobile phones use lithium batteries. The best way to maintain lithium batteries is to keep them fully charged.
It should be noted that the natural enemy of lithium batteries is high temperature, so we don't recommend you to charge while playing large games, which will lead to serious fever. Secondly, the current Apple mobile phones are all designed with a double-layer motherboard, which has poor heat dissipation. If you play games while charging at this time, it will undoubtedly generate twice as much heat as other mobile phones, which is fatal to lithium batteries.
Second, choose a regular charger to charge. Apple supports 18W fast charging, but Apple doesn't come standard with 18W fast charging (this year's 1 1pro /MAX has come standard), users need to buy it themselves, but Apple's official fast charging is too expensive, so many people will choose to buy a third party.
If it is a third-party Apple-certified fast charger, it is fine, but if it is some fast chargers without Apple certification, it may cause harm to our Apple mobile phone.
Based on this, we do not recommend that you use chargers and charging cables without Apple certification, including roadside charging treasures. We don't recommend them. Such a charging cable may have quality problems. If you are caught, the damage to the battery will be huge.
Generally speaking, as long as you don't play with your mobile phone when charging, always keep the battery charge at 40% to 100% and use the officially certified charger and charging cable, the battery health of Apple's mobile phone will be protected to the greatest extent.
