Why is the mobile phone battery dying fast?

What if the mobile phone battery is not durable? I stayed in the house for a long time in the winter, and finally got the courage to decide to go out. I'm sure the phone is full charged before I go out in a good mood. There is beautiful scenery everywhere, I take out the phone and ready to record this wonderful moment, the phone power is only 90% left. After taking a few photos, the phone prompts low battery. Did anything like that happen to you? The phone inexplicably lost power quickly, especially in the cold winter it is easy to automatically shut down. So what's the reason the battery of your phone is dying so fast? What if the cell phone battery is not durable? The following IT encyclopedia will give you answers.

One of the reasons cell phone batteries die fast is that the extreme temperature causes the battery to go into a temporary shock.

Apple officials say the best operating temperature for the iPhone is between 0 C and 35 C, with an ideal range of 16 C to 22 C. In fact, the normal operating temperature of most mobile phones is about the same. Our mobile phone battery is generally lithium polymer battery, through the electrical energy, chemical energy, electrical energy chemical reaction to charge and discharge. This chemical reaction is easily affected by the temperature. When the temperature is too low, the chemical reaction speed of lithium battery will be greatly reduced. Therefore, the discharge current of the battery becomes smaller, which directly leads to the decrease of the available capacity of the battery.

And that's why in very cold conditions, you see a decrease in battery life, a jump in battery life, maybe from 50% to 30%, maybe even a shutdown. But don't worry, the condition is reversible and doesn't actually cause battery damage. When the battery temperature returns to normal operating range, its performance will also return to normal. At this point, you should be aware that high temperature environment can also cause damage to the battery, and this damage is irreversible, so we should try to avoid the phone in a temperature higher than 35 ° C environment, or it may permanently damage the battery capacity.

Second, poor cell phone signal leads to fast power consumption.

IPhone users may have noticed that when we use cellular data to surf the web, we lose power significantly faster than when we use WIFI. This is because when you're in an area with poor cellular data coverage, the signal is weak, so the phone USES more power to receive and transmit the signal to keep the connection stable. So you will also feel that the phone battery is not durable, especially fast power down.

Third, the actual battery capacity has been very low, resulting in fast battery loss.

In fact, our mobile phone battery has a life, this is due to the parts of mobile phone battery will gradually aging, in the process of we use lithium ion concentration will reduce gradually, this led directly to mobile phone battery capacity decreases continuously. Under normal use, a cell phone use for a year or two, the battery had big as before the actual capacity. That's why we feel the main reason of the cell phone battery is not durable. So how do we see the residual capacity of battery actual? Here is a simple and quick way to download an APP directly from your mobile phone to view the details of the phone's battery, such as battery manager, battery doctor, etc.

Above is the cause of the common mobile phone battery off the electricity quickly, because of environmental factors, because the battery itself. The cell phone battery is not durable? Here, IT encyclopedia give you some tips to save power.

1. Turn the screen brightness

Screen as the portal of human-computer interaction, is also a mobile phone and power-hungry, arguably, the impact on the life especially the phone's screen, most smartphones now have a light sensor, I suggest everyone open automatic screen brightness, the phone will automatically according to the bright degree of the surrounding for you to adjust the most suitable screen brightness; Of course, if you want to save more power or need to improve the battery life in an emergency, you can turn off the auto-brightness adjustment function of the phone and directly adjust the screen brightness to the lowest brightness that you can see clearly, which will effectively extend the use time of the phone.

2. Reduce the screen resolution

The most intuitive benefit of a higher screen resolution is a clearer and more detailed display, but it also results in greater power consumption. On the one hand, it takes more power to light up more pixels; on the other hand, it takes more CPU/GPU load due to the higher resolution. So there's no question that lowering the screen resolution will extend battery life. Note that the resolution reduction here refers to the reduction of pixel display points through the software algorithm, and the physical resolution remains the same. Of course, this power-saving trick only works on some high-resolution android phones, not the iPhone.

3. Close application startup

Application startup can be said to be a common problem of Android phones. Due to the openness of the Android platform, the operating system is not so strict about the control of applications. Therefore, there are a lot of rogue software is often in the background since the launch and some also can arouse other one or more APP, leading to cell phone no electricity. We can set in closing these unusual since the launch of the software, in addition, we also want to pay attention to clean up the background applications more at ordinary times, avoid unnecessary application permanent memory.

4. Close the GPS function

When we go out, if we do not use the mobile phone GPS navigation, try to turn off the mobile phone positioning function. If we do not turn off the GPS, it may continue to locate for you, resulting in meaningless power consumption of the mobile phone. When going out for navigation and looking at the map, you can turn off the navigation software first if you know where the destination is after looking at the map. Mobile phone navigation is very power-consuming.

5. Open the power saving mode

In view of the current battery technology bottleneck, hardware can not break through the situation in a short time, various mobile phone manufacturers from the software, have launched their own energy-saving mode, apple is no exception. When power saving mode is turned on, the system will automatically reduce the CPU frequency, screen brightness and screen resolution, limit the application networking in the background, reduce the rendering of display effects, and stop cloud service data synchronization and other functions. Improve battery life by reducing these non-essential features.

After all this, do you understand why your phone's battery is dying? What if the cell phone battery is not durable is a common problem in the use of smart phones. Hope the above tips to save electricity can help you.
