1, iphone motherboard and battery have protective measures, which will cut off the input when it is full, so it can be said that the damage to the battery is negligible. In the future, the iphone will prompt 20% power, and everyone can charge. Never wait for the battery to run out before charging, that is, charging and using. Deep discharge is harmful to the battery.
2. Can't the 2.iphone battery work? Yes, it's really not durable. Everyone trusts Apple's optimization too much. You should know that the iphone battery is only 3000mAh at most, which is a hardware limitation. Which part of Apple's mobile phone saves electricity? CPU, GPU coprocessor? Stop it, the processor is so big, the technology is not advanced, the battery is dragging its feet, and the screen consumes a lot of power.
There are still some aspects that Apple has been saving materials in recent years, and the parts have shrunk seriously. 5s Sony battery is not needed, and a bunch of spare tires ATL COS SDI LGC have been used. The battery indicator has not been replaced since 6. Can you believe it?
3. Factors that affect the health of the battery: The temperature that affects the most, when everyone doesn't think the temperature is very low or high, charging is very slow? That's right. If the temperature is too low or too high, the protection device on the motherboard will start to protect the phone and battery. In fact, coulometer is not enough. Just charge at room temperature. Try not to play games when charging. If the temperature is low, install a game, run it and charge it.
4. I don't know what is the truth of the 6S automatic shutdown door? Anyway, the 6S and 6SPLUS around me are not automatically turned off, and the coordinates are all in the Yangtze River Delta region, but 6S, 6S PLUS, 7,7 Plus are all the same meter. It is not clear whether it will automatically shut down in large quantities after one year.
5. The battery of iPhone 7 is waterproof, but don't go into the water, or the water will break, and Apple won't guarantee it, because Apple even saves waterproof glue.
6. The battery is a consumable. Let's relax. If the loss is more, please replace the battery. Many friends bought batteries on Taobao, and many sellers claimed that 0 was defective. I can tell you that many unscrupulous merchants use machines to exchange them. The original factory generally has 1 ~ 2 defective batteries, and those batteries are exposed as long as they are connected with professional tools. And those DIY high-capacity batteries. I have seen many people change, and I am also holding a wait-and-see attitude. I'm worried about the source of the battery and those parts and the reliability of the burning parts.
