preface

The development of mobile phone battery seems to have reached a bottleneck stage. The way to extend the battery life of mobile phones is to continuously increase the battery. The technology that can fundamentally change the status quo does not appear yet. For example, Motorola's 3300mAh "Viagra Blade" Razr Maxx and 3100mAh Galaxy Note II are good examples. In addition, multi-core CPUs also reduce power consumption by continuously improving the manufacturing process, such as 28 nm for Qualcomm S4 and 32 nm for Samsung Exynos. This article mainly introduces how to extend the battery life of our mobile phones through some settings, software, etc. As the saying goes, do it yourself and have plenty of food and clothing!

1. Loser method

Adjust to power saving mode

Many mobile phones have the so-called "power saving mode". The author believes that it is unnecessary to keep this mode open for a long time. A good high-frequency processor needs to be used at low frequencies. Why? Of course, if you really need to extend the battery life in an emergency, you can still consider opening it.

Set the network mode to GSM

This is also an option similar to the power-saving mode. If users can access 3G, there is no need to lock the GSM to achieve the purpose of power-saving. It is not advisable to sacrifice the experience of 3G Internet access in exchange for endurance.

2. "General" Approach

Turn off automatic brightness

Automatic brightness is a basic function of mobile phones. It is a good function to adjust the brightness of the screen by using light sensing. Why turn it off? In actual use, we found that the automatic brightness adjustment of many mobile phones is actually not good, and the brightness often does not meet our actual needs. In addition, if the automatic brightness adjustment is always on, the light sensor will work all the time, increasing the power consumption. It is recommended to turn it off.

Turn off Bluetooth and WLAN

This is a platitude, and I believe there is no need to explain it. One thing to mention here is that iOS WLAN and Bluetooth are "insidious". If they are not in use, the taskbar will not prompt, which causes users to often forget to turn them off.

Turn off GPS

This is also a common method, but the iOS closed location method is relatively hidden, in Settings → Privacy → Location Services.

Close NFC

NFC is a feature only available in some high-end mobile phones, which has gradually increased in recent years. It can realize a variety of data exchange, but it also consumes power silently in the background, and is insidious, similar to Apple's WLAN and Bluetooth. Therefore, it is better to turn it off if it is not used.

Turn off the key light

The function of turning off the keyboard light is not available on every mobile phone, but it is very practical. It is recommended to turn it off directly.

Meizu's keyboard light can also adjust the brightness

Turn off key sound, touch sound and vibration

These optional functions should be turned off to avoid power consumption. Power saving should be maximized!

Close action

These are some unique somatosensory functions of Samsung, but opening them will trigger the opening of many sensors, such as "quick overview", "intelligent prompt", "shake to update" and other infrequent functions.

3. "Literature and art" method

Turn off the startup item

Many software unknowingly consumes power in the background. It is not easy to find them out. Common mobile phones need to install some third-party software after obtaining root permission to turn off the startup item. (The "Lizuo Toolbox" is used here.).

It can even turn off the automatic startup item of the network, which prohibits the automatic push of many software. It is also a very practical function.

The big cola mobile phone (Lefrog rom) has its own ROM, so you can select the startup option.

Turn off music playback equalizer

For iOS devices, the performance of the equalizer is really poor. It is recommended to turn it off directly to save power. Android phones can also refer to this method.

4. "Technology flow" method

Frequency and voltage reduction

As Android, which is famous for its openness, there must be an exclusive method for technology flow. Here we introduce how to adjust the frequency and voltage of CPU and GPU by brushing the kernel and matching with third-party software. This is a relatively advanced power saving method. Of course, we need to constantly try and adjust to find the most appropriate frequency and voltage.

Adjust CPU frequency

Usually used here The author also thinks that it is not necessary to reduce the frequency. I really think that this is a problem because of the excess performance.

CPU frequency policy regulator

By adjusting the CPU frequency strategy, Lazy and ondemand can save more power.

CPU voltage

That's the point! The voltage shall not affect the stability, and the lower the voltage, the better.

GPU voltage

Same as above
