My mobile phone is used too fast.

There are many reasons why mobile phones consume power quickly. External power consumption as long as you unplug the things that use electricity. The key is internal power consumption, which will be consumed if you are not careful.

First, distinguish between external power consumption and internal power consumption.

External power consumption:

The power supply is reversely output through the mobile phone interface OTG, such as USB fan, lamp, mouse, keyboard and a series of things that can be powered through the USB interface. These gadgets don't seem to feel anything, but they consume a lot of electricity.

Internal power consumption:

This part mainly refers to the transfer mechanism of flash, camera, screen, speaker and other hardware and system software. The most power-consuming part of most mobile phones should be the screen. Because under normal circumstances, the interaction between mobile phones and people is carried out through the screen, so basically as long as you use the mobile phone, the screen of the mobile phone will light up.

Take Red Rice note2 (a semi-finished mobile phone produced by Chestnut Xiaomi in August of 20 15), which is equipped with MTK Helio X 10 ten-core processor (that is, the God U with one core and nine cores looking at the wind), and then use Tianma Screen (it seems that Xiaomi was sued in that year, so you can go and see it if you are interested).

The key point is that in a complete power consumption cycle (100%-3%), due to the magical operation of this generation of God U, the processor actually only accounts for less than 10% of the power consumption, while the screen power consumption is as high as 80%. Light up the screen and the power begins to collapse.

After finishing the screen, I walked to the camera. This is also a big power consumer. Generally, it consumes electricity with the screen, except that some people like to put their cameras on the screen to take pictures. Basically, neither of the two brothers has run away. The most intuitive thing is to turn on the shooting mode, and the calorific value of the mobile phone will rise sharply.

For example, in time-lapse photography, the camera is always on, and most mobile phones can't last for three hours. It is not easy for a small-capacity mobile phone like iphone to last for two hours.

Compared with cameras and screens, flashlights and speakers consume much less power, but the overall power consumption is not optimistic. Fortunately, there are not many usage scenarios, and the overall duration will not be too long.

Finally, it is about the system software. The system is delicate and complicated, and I, an amateur brush machine lover, don't know much about it. Generally speaking, when the mobile phone enters the background standby state, it will test the adjustment mechanism of the system. In order to improve the response speed of software, most of them choose to keep high-frequency software in the background except those with AI preloading function. This has caused the burden on the processor and the biggest culprit of standby power consumption.

Back to the question, why do mobile phones consume so much power? Because today's mobile phones need to be equipped with the most functions in the smallest possible machine in order to meet the demanding requirements of the great gods. The battery will have to shrink. After the battery is small, this battery life will be significantly reduced, so the manufacturer will definitely solve it, and then achieve the purpose of saving electricity through software. Unfortunately, not all manufacturers have excellent system-level power saving algorithms, so negative optimization emerges one after another. So to sum up:

The answer is that the mobile phone battery is small, the power saving algorithm is negatively optimized and the hardware energy consumption is high.

—————————————— dividing line.

There is also a special case that there is a problem with the mobile phone and the hardware of the mobile phone itself is faulty.

1. Battery life is shortened. Usually, everyone will have this habit: using a mobile phone while charging is extremely harmful to the battery. Mobile phone battery is a lithium battery (chemical battery) that stores electric energy through chemical reaction, and can be recharged many times. Using it while charging will accelerate the aging of the battery. Generally speaking, avoiding this habit can prolong the aging speed of mobile phones by about half a year.

2. The motherboard parts are damaged (falling, water, high temperature, cottage charger, etc.). ), resulting in short circuit leakage of the motherboard. It shows that a fully charged battery can consume more than 30% of electricity in one morning even if it is not used and replaced. The most serious problem caused by this kind of fault is that once the power is exhausted, it can't be recharged. It is troublesome to activate the battery with a current stabilizer (I have tried many times and it is terrible)
