Why does my mobile phone battery run out so fast?


When buying a smartphone in a trade we often have the good (or bad) habit of paying attention only to how well the screen looks (it will always be as bright as it gets), how fast it is surfing the internet ( With a large WiFi connection) or the brilliant photos taken by the camera from the mobile phone (always obtained in bright light and in good condition). Of course, little (or null) importance we give the battery, a vital section that often goes unnoticed and whose autonomy is one of the biggest challenges of mobile technology.


In recent years there has been a lot of progress in this area, in the case of fast charging technologies or external batteries. Be that as it may, they may not be enough for those more demanding users who wonder why the autonomy of their brand new smartphones does not give them to reach the end of the day.


Why is the battery so short? What does it depend on? And how can I extend the autonomy of my smartphone? Concrete is not an easy task, since the battery life of a smartphone depends on many factors. “The way we recharge it, the use we make and even the ambient temperature and humidity can lengthen or reduce autonomy by more than 30%,” explains Álvaro Galán, Product Marketing Manager at Huawei. “All these factors not only influence the autonomy, but also in the life of use of the battery. Therefore, responsible use prolongs the time of use and also the period in which the battery will remain in optimum conditions, “he says.


First of all, one of the great references to know the autonomy of a terminal is the capacity of the battery, expressed in milliamperes / hour (mAh). In fact, today an acceptable battery is assumed to be around 3,000 mAh, although there are already terminals in the market that exceed 5,000 mAh. To a greater extent, more autonomy should have our terminal … a priori. This is not always the case. “The capacity in mAh should not be the only indicator that we use to evaluate the battery life, depends on other factors: it is important to have efficient hardware, a latest generation processor, components that dissipate little heat, low power displays , Quality battery, etc. “, explains Álvaro Galán. They are aspects that depend on each manufacturer, which greatly influence the user experience of each terminal … and that usually do not appear in any basic datasheet.


How to extend autonomy?

Among all the components of a mobile, the screen is the section that most battery consumes in the day to day. “That’s why it’s important to have a good panel and low-power technology,” says Huawei’s Product Marketing Manager. Beyond the hardware that incorporates the smartphone, the user also has in his hand to stretch the autonomy of his terminal carrying out practices as simple as diminishing the brightness of the panel, shorten the time of shutting off the screen, etc.


However, the optimization and battery-saving mechanisms that incorporate mobile software should not be overlooked either. “Controlling the processes and applications that run in the background, optimizing memory resources and managing connectivity needs also influence autonomy,” explains Álvaro Galán.


Many users do not even raise it, but the truth is that connectivity is another important section in the daily consumption of our battery. “We usually fix Wi-Fi connectivity, Bluetooth or GPS, when for example being in a good coverage area helps a lot because it prevents a constant adjustment with the network. An example of (major) battery consumption is found in an area with little 4G coverage where we are continually jumping from 3G to 4G and vice versa, “adds the Product Marketing Manager at Huawei.
