Some knowledge of the iPhone 5s lithium battery

Many iPhone5S users after iOS 7.0.6 complain that the device has faster battery consumption and problems with heat dissipation. According to the foreign media OSXDaily report: "In some cases, the battery consumption becomes very fast, and the user can basically count the percentage of the battery." Among them, the battery and cooling effects brought by the iOS7.0.6 update are especially serious for the iPhone5s device.

So what should we do if the battery consumption is so serious? The solution provided by the Apple Support Community for this issue is as follows:

Hard start the device by holding down the Home button and the key for 10 seconds simultaneously. However, before a forced restart, the user needs to keep the device in a multitasking state (double-click the state where the Home button appears) to close each application.

Obviously this method is troublesome and we can only expect Apple to re-update the next system. However, since it comes to the battery, Xiaobian is here to analyze the maintenance of iPhone5s lithium battery, charging tips and common misunderstandings.

Most of the misunderstandings about the use of lithium batteries are due to misunderstanding of related terms, so it is necessary to explain them specifically.

1, memory effect: Nickel-hydrogen rechargeable battery common phenomenon, the specific performance is: If you start using the battery if you are not fully charged for a long time, the battery's power will drop significantly, even if you want to be full in the future is also full of dissatisfaction. Therefore, an important way to maintain NiMH batteries is that the electricity must be used up before it can start charging. If it is fully charged, it is allowed to be put into use. The memory effect of commonly used lithium batteries can be negligible.

2, fully charged, fully discharged: this is for lithium batteries. Complete discharge refers to the process of adjusting the power consumption smart device, such as a mobile phone, to the lowest power state until the mobile phone automatically shuts down. Fully charging refers to the process of fully discharging a powered smart device, such as a mobile phone, to the charger until the phone says “full”.

3. Over-discharge: After full discharge, if other methods continue to be used, a small amount of power will remain inside the lithium battery after complete discharge, but this part of the power is crucial for the activity and life of the lithium battery, such as: forcibly turning on the mobile phone and battery again. If the small light bulb consumes residual power, this is called over-discharge, which will cause irreversible damage to the lithium battery.

4. Protection chip: The lithium battery has extremely strict requirements on the current and voltage of the battery when it is charged and discharged. In order to protect the battery from being damaged due to abnormal external environment, a chip for managing the working state of the battery will be set inside the battery body. This chip also has the function of recording battery capacity and correcting battery capacity. Now, even if it is a cottage mobile phone battery will not save this key protection chip, or the cottage phone battery cannot be used for a long time.
