Usually, the rated life of cell phone lithium batteries is 500 times longer. In fact, it would be nice to be able to charge and discharge for 400 cycles!
The batteries in most smartphones are lithium batteries. Although Apple mobile phone is considered a high-end smartphone, its battery is not special and is also a lithium battery type.
According to some laboratory test results, the lifespan of lithium batteries is about 500 times. Seeing this, my friends, do not be nervous. The so-called 500 times does not mean charging 500 times, but refers to the manufacturer's constant depth of discharge.
During daily use of cell phones, when we charge cell phone batteries, the depth of discharge achieved will change. The so-called 500 times lifespan is just a valuetheoretical, and these 500 times refer. At "500 charging cycles", it may take several times to count as one charging cycle. In other words, a cell phone battery can be used for about 3 years. This has a certain relationship with the frequency of charging. usage and the number of charging times.
For lithium batteries that meet the GB/T 18287-2000 standard, the official lifespan is >300 times. >Regarding the material of Apple batteries, we should mention the "GB/T 18287-2000" standard for batteries, which is customized for lithium batteries. The batteries supplied by major Apple battery suppliers to Apple are. compliant with this standard, which means that Apple batteries use "lithium batteries".
We can refer to Figures 1, 2 and 3 below for the test items and indicators of the standards. of implementation of “GB/T 18287-2000”.can confirm that Apple batteries are lithium batteries.
How to use Apple mobile phones with long battery life
1. Today's iPhones all use lithium polymer batteries:
Lithium polymer batteries (Li. -Polymer, also known as lithium polymer battery): Compared to previous batteries, It is a high-energy, miniaturized and lightweight chemical battery. In terms of shape, lithium polymer batteries have ultra-thin characteristics and can be made into batteries of different shapes and capacities to meet the needs of certain products. The theoretical minimum thickness of this type of battery can reach 0.5 mm.
2. In order to increase battery life, the upcoming iPhone 7 may increase battery capacity, but Apple will not take this simple approach.
3. Apple filed a patent applicationand for a hydrogen fuel cell: will the iPhone 7 last a week?

1. The battery cannot be used until it is completely exhausted, because Apple mobile phones are lithium-ion. Leaving the battery charge below 20% or charging it after it is depleted will destroy the chemical activity inside the lithium battery and cause the battery life to age. 2. When you can't sleep at night, leaving your phone on all night will hurt battery life. Since the lithium battery is continuously charged at 100% power for a long time and at high voltage, the battery will age faster. 3. Charge the phone to 100%, then unplug it. If the phone remains charged at 100%, the battery will be in a high voltage state. 4. Always maintain the bat levelerie of your mobile phone between 65 and 80% and the battery life will be longer. This method is suitable for most Apple brand mobile phone models. Therefore, you can charge your iPhone anytime and anywhere, and you cannot charge it until the battery runs out. Also, do not pay too much attention to the battery health, as the battery is a consumable item and will age after prolonged use.
