Love to play computer games From now on, the "1 Q N A" column will be officially launched, and representative questions will be selected from the WeChat and Weibo interactions with friends of the machine, and will be answered irregularly.

WeChat friend Mr N (V) ice: Ask Nongigo why my g12 consumes power quickly in flight mode. The full grid will disappear overnight, and this will not happen when I start up.

Xiaoji answers: This is very normal. When the plane is flying, it must consume more fuel than when it is parked on the ground, so the small plane usually does not turn on the flight mode of the mobile phone, for fear of power consumption

Answer from Feiwei VV : Refresh the machine or restore the factory settings?

Best Answer:

First, let's understand what flight mode is.

[Flight mode]: The flight mode of the mobile phone is also called aviation mode and flight mode. After the flight mode is turned on, the GSM/GPRS module of the mobile phone will be stopped. The mobile phone does not transmit and receive signals, but it can generally make emergency calls. At present, there is no industry standard for flight mode in the mobile phone industry.

Back to the problem of power consumption in flight mode. For function phones, most of the power of the mobile phone is consumed by the signal. The flight mode turns off the signal, so it will save a lot of power. But for smart phones, there are many reasons for power consumption, which need specific analysis.

1) Background application power consumption

Flight mode only turns off the signal and network connection, but at this time, the applications and software that have been opened in the background will not rest because of the flight mode, but will try to connect Wifi, transmit data, synchronize information, search Bluetooth and other functions. Some software will still try to connect repeatedly when it is unable to connect to the network, which will increase the power consumption in flight mode.

2) System instability

Organic friends will ask, I go to bed every night after killing the process, but why do I still lose power? At this time, it is not safe to check the system. Many mobile phone users will often swipe their phones or escape from prison after they get their phones. Sometimes, because the swiping package itself is unstable, there are bugs, which may cause an increase in power consumption.

For example, some netizens found that AudioOut_1 is always active even when it is in standby mode when the touch screen sound and lock screen sound are turned on after brushing 4.0, which prevents the mobile phone CPU from entering full sleep, resulting in increased power consumption. This kind of situation can be solved by disabling the corresponding function or brushing the stable version of the software.

3) Problems with power supply and other components

If the power consumption still exists after the above two problems are eliminated, it is necessary to consider whether there is a problem with the power supply components or internal leakage.

Detection method: use a power consumption monitoring tool such as CurrentWidget to monitor whether the power consumption of the Log file is normal. If the power consumption of the same mobile phone is too high, it is likely that it is an internal component problem.
