The optimal operating temperature of the iPhone is between 16°C and 22°C. When the ambient temperature is near or below 5°C, the density of the battery electrolyte will be reduced, leading to deterioration of battery performance and weakening of discharge capacity, causing the battery to automatically shut down. device when powered, causing random jumps. power values and charging difficulty. This is a problem for lithium. Due to the temperature characteristics of the battery, pay attention to the insulation of the machine. Let it warm up in a high temperature room and it will return to normal. You can usually put it in the inside pocket of a body temperature coat.
Should iPhone 8 battery be drained and recharged?
How to make iPhone 8 battery last longer We all know that Apple mobile phone battery is notnot very durable? sustainable. It will last one or two years. It's time to replace it with a new one. In fact, it's often because we use it incorrectly. Let's share some methods to tell you how to extend iPhone 8 battery life.
1. Avoid using fast charging
Many friends who own an iPhone also own an iPad. They probably all know that charging an iPhone with an iPad takes longer than using it. However, any type of fast charging technology will increase the battery temperature to some extent, and high temperature is actually one of the reasons for battery wear, so if it is not necessary, all the world should use normal charging speed, which will be faster than using fast charging which makes phone batteries last longer. Additionally, you can also reduce battery lossie caused by high heat when removing the cell phone case when charging.
2. Avoid using the phone while charging
Although many friends are accustomed to using a "power bank" to charge their cell phones while playing games or continuing to browse the web. Web, this is not as fast as using it. The reason for the charge is similar. Charging and using the phone all the time will significantly increase the battery temperature, which is more likely to consume battery life than fast charging.
3. Try to keep the battery between 40% and 80%
Old “eco-friendly” nickel-metal hydride batteries have a “memory effect” if the battery is. not completely exhausted after first use, for example, if the battery still has 20%, charge it to 60% then use it. The memory effect will cause the battery will no longer be able to use just below 20% and. above 60% capacity, which will shorten battery life. Big discount. However, the structure of currently used lithium-ion batteries can be considered to be opposite in principle. Additionally, there is no memory effect and the batteries also wear out due to overheating.
Frequently draining the battery to 0% and then automatically turning it off will not only cause the cell phone battery to continuously consume charging cycles, but may also cause the battery to "deep discharge" at lithium, which will cause "deep discharge" of the lithium battery. also increases battery loss. In fact, Apple's official website mentions that the optimal operating temperature of the iPhone battery is between 0 degrees Celsius and 35 degrees Celsius. If the user plans to store the phone for a long timee period and not using it, it is best to charge the device. reduce by half before storing.

Under normal circumstances, if Apple batteries have only 80-85% remaining, the normal usage life should be approximately 2 years. Battery capacity cannot be artificially increased unless the battery is replaced. You have to pay attention to it every day. For protection, it is best to turn off and charge first. There is no power output and the temperature is relatively low. Apple mobile phones can often be used for more than 3 years. replace the battery when it reaches 80%.
Precautions for charging mobile phones
1. It should be noted that the best way to charge your cell phone is to not charge it for a long time. When themobile phone battery is exhausted, it is necessary to charge the mobile phone in time. Do not wait until the mobile phone battery shows 0 before charging the mobile phone. Otherwise, battery life may be shortened.
2. When charging your mobile phone, do not charge it for too long. Do not leave your phone charging, otherwise it will reduce battery life. It is best to keep the mobile phone battery charge between 50% and 70%. When charging, when the mobile phone tells you that the battery is full, remove the charging plug immediately.
3. It should be noted that when charging the mobile phone, it is best not to charge the mobile phone overnight. Since smartphone batteries are usually lithium batteries, charging the phone overnight will affect battery life.
