1. Here are some ways to extend the standby time of mobile phone for your reference:
1. Bluetooth, WLAN, GPS, camera, browser and other related applications. It is recommended that you close these functions in time after using them
2. Turn on the power saving mode or super power saving mode of the mobile phone
3. Rece the backlight time
4. Turn down the brightness of the display screen.

3. Rece the backlight time
4. Turn down the brightness of the display screen.
2. Look at your graphics card and CPU model. If it is not too old, the CPU and graphics card will automatically rece the frequency in the case of standby or low load of ordinary Internet viewing. Especially for the graphics card, the frequency will be greatly reced, and the power consumption can even be reced to more than 1 / 4 of the full load power consumption. For example, for gtx660, the frequency of full load GPU is 980MHz (excluding boost), the frequency of video memory is 6000mhz, the frequency of standby GPU is only 324mhz, and the frequency of video memory is only 648mhz. Intel's CPU frequency is not reced much, usually by half. But the standby frequency of AMD's CPU will drop sharply. Other models are not clear. My daughter-in-law's AMD x4940 standard frequency is 3000MHz, and the low load frequency is only 800MHz. This is also why AMD's CPU full load power consumption is much higher than Intel's, but the standby power is not much worse.
3. The power consumption is directly proportional to the performance of the hardware. To rece the power consumption, it is not necessary to open a few programs and replace the low-power hardware, but it also means that the performance of the machine is declining
4. This effect is not big, we can only consider heat dissipation.
5.
There is no way to rece the power consumption, as long as it is not overclocking

7. In recent years,
with the rapid development of mobile Internet and the rapid growth of mobile users, the requirements for high-tech instries, especially smart phones and information and communication technologies, are becoming higher and higher. Among the newly launched portable mobile devices, mobile phones are more multimedia and intelligent, and the hardware is equipped with advanced micro processor chips, In the software system, various system applications such as media player and web browser are installed. With the
development of the mobile field, the dominant frequency of smart phones equipped with Android system is higher and higher, the CPU core is more and more, the screen size is larger and larger, and the resolution is higher and higher, which not only brings higher performance and better user experience, but also has some disadvantages. That is, the battery's enrance can't increase effectively in proportion to other items. The main reasons for power consumption in hardware devices are as follows:
1

3. WiFi and Bluetooth devices are on for a long time< 4. Signal receiving and transmitting of baseband chip
5. Audio and video devices are playing for a long time
6. GPU in 3D rendering data processing
7. Various sensors and other peripherals use polling or interrupt to monitor environmental data
8. The system reads and writes data to the memory

for the hardware, any of the above cases occupy a considerable proportion in the power consumption of the device. For the above devices, the following advanced hardware is equipped in the chip structure of qcomm snapdragon:
1. CPU adopts 28nm process, krait 400, more than 2G main frequency
2. GPU adopts advanced Adreno 330< br />
3.Hexagon DSP;
4. The wireless chip integrates 4G LTE baseband chips supporting all modes, WiFi, Bluetooth 4.0, RF, USB3.0 and other high-speed devices
5. Audio and video decoder
6. Low power sensor

Android application software usually uses one or more of these hardware, and the power consumption mainly comes from hardware, Through the following several ways to explain how to minimize the power consumption of application software
application software and wearable devices, such as smart bracelet, collect data for health, exercise and other behaviors, and send it to the application software of Android mobile phone through Bluetooth. When the Bluetooth device is turned on to collect data, the application software will receive and monitor the data sent by the bracelet. When the data is received, the application software will receive and monitor the data, The application should pop up a dialog box to prompt the user whether to turn off the Bluetooth device of the system, so that the user can choose whether to continue to use or temporarily turn off the Bluetooth device. When the application exits, the Bluetooth device should be turned off. At the same time, Bluetooth 4.0 adopted by Qualcomm can speed up the data transmission speed, thus shortening the running time of Bluetooth and recing the power consumption
motion monitoring application software. Now some application software can calculate the distance, average speed and the trajectory on the map ring a certain period of time. In fact, this application software consumes a lot of power
and needs to use the network provided by the baseband chip to download maps, turn on GPS to locate the user's location, use GPU to render 3D images, and the CPU is running at a high speed. When making this kind of application software, we should
provide offline map download, or download and store the map locally when the user first uses it, because the user's exercise habit often uses the same track; The positioning function and data acquisition of GPS should be
turned on when the user chooses to start timing, and turned off when the user chooses to end timing, while Qualcomm izat & 8482
GNSS
GPS is a high-precision positioning system with three satellites, so the CPU will also process a lot of data after collecting data. Because the CPU and GPU of Qualcomm have strong data processing ability, the CPU and
GPU run for a short time, which greatly reces the power consumption of the system. Therefore, this method will not only save the power consumption of network download through 3G and 4G signals, but also shorten the GPS positioning time
to the shortest, thus recing the power consumption
video or reading application software, which generally needs to turn on the screen for a long time. Qualcomm uses 2K high-definition screen and 1080p high-definition wireless display. Generally, the higher the brightness, the greater the power consumption. The display of the screen should be divided into day and night modes to adapt to the brightness of the screen, For reading software, when the user does not operate the screen for a long time, the software should rece the screen brightness to the minimum; For video software, the screen brightness should be adjusted automatically, and users can adjust the brightness manually according to their own habits
as the background service of application software, Android application can start a service and start a thread to make the application run in the background, such as new message notification, version update, friendly reminder and other push services. When users open these asynchronous notifications, they jump to the application directly. In fact, the app
store, pea pod, and all kinds of mobile app market shelves contain the push service. When users start a lot of applications, it is conceivable that there will be a lot of background services, which occupy a large amount of memory. The CPU has been running at a high speed. At the same time, they need to use the network, such as WiFi, 3G and 4G signals, which will consume a lot of power. At this time, when the application software starts this thread, it can extend
polling time, rece the running times of push service, and make the system sleep as much as possible, so as to give up CPU resources; Or just let the background service detect whether there is a network, if not, set a longer sleep time; If it exists, judge whether it is WiFi network or 3G, 4G signal network. If the former, it can shorten the sleep time of the system. If the latter, it can still make it sleep longer. This not only ensures that the function is not affected by
but also saves traffic and reces power consumption
the application software involves the function of screen rotation, because the automatic rotation of the screen depends on the operation of G-sensor for data acquisition through polling, and the gravity sensor for data acquisition through polling,
so it consumes more power. When the software is in full screen mode, the function of gravity sensor can be disabled. At the same time, the low-power sensor chip adopted by Qualcomm can further rece the system power consumption
application software involves the function of data download. Data download needs to be carried out in WiFi or in the presence of baseband signal. The WiFi used by Qualcomm has fast transmission speed. At the same time, baseband chip supports full-mode mode mode
mode, and the most important thing is that CPU processing power is very fast. Multithreading download mode can be used when writing application software code, It shortens the download time, reces the WiFi on time, and reces the CPU data processing
time. Compared with single thread low-performance download, it can save a lot of power consumption
Android applications are written with different logic codes. Whether the power consumption can be reced or not depends largely on the hardware of the system chip. At this time, we can use the tool trepn & 8482provided by Qualcomm to test the power consumption; Plug in combined with eclipse software for testing, which algorithm or logic design used in the application software can better match the hardware of the system, need to constantly try to achieve the goal of better user experience and lower power consumption.

8. Yes, but it seems that it needs the support of motherboard and CPU. For example, ASUS motherboard installed with epu-4 engine software support energy saving! I also get it online, but I don't know if other brands of motherboards are compatible. If the graphics card, the next overclocking software will rece the frequency to achieve the purpose of energy saving. Basically, the CPU utilization rate of downloading files is very small, and the general energy-saving engines will automatically return to the original power with the increase of task pressure. If the CPU fan is equipped with automatic speed control function, it will greatly alleviate the noise problem.
9. Hello, No. every generation of iPhone pursues the ultimate design and performance. If you look at the parameters, you can see that not only the performance has been improved, but also the battery capacity and enrance have been improved.
