LR6 alkaline battery.Mobile phone battery technology analysis

　　When purchasing a mobile phone with an ultra-long standby time, it is recommended to check the battery capacity. Products with abnormal battery capacity of around 2000mAh to achieve ultra-long standby are not highly recommended. You should also be wary of brand-name mobile phones with unknown origins. Power-hungry display screens Whether it is a smartphone or an ordinary mobile phone, battery has always been a crucial element when everyone chooses a mobile phone.

　　Indeed, once the battery is out of power, no matter how powerful your mobile phone is, it is just a piece of scrap metal. The battery performance of many mobile phone products on the market also varies greatly. So what are the factors that affect mobile phone battery life? The display is first of all the screen of the mobile phone. This is also obvious. We often find that the nominal standby time of many mobile phones is seriously inconsistent with our actual use. When you really fully charge it and put it there to see if there is anything wrong with the battery, The standby time can indeed be basically close to the nominal value.

　　This is the factor of screen power consumption. In most standby conditions, the screen is turned off, so there is no need to consume power for the display. If you have more text messages or are more likely to use your phone for other reasons, it will inevitably cause Reduction of battery life.

　　Generally speaking, the larger the screen of a mobile phone, the more power it consumes, the higher the brightness, the more power it consumes, the higher the resolution, the more power it consumes, and the higher the color number, the more power it consumes.

　　Not only the power consumption of the display itself will increase with the above elements, but as the screen resolution and color number increase, the requirements for the system chip will also increase, forcing the use of higher frequency The processing chip has to cooperate with it, and the power consumption will increase exponentially.

　　Chips and network communication chips are the same as computers. Everyone hopes that the chip will be as fast as possible and the performance will be as powerful as possible, but powerful performance is based on high power consumption. Therefore, the battery capacity of the smartphones we usually see is often much larger than that of ordinary mobile phones. Moreover, mobile phone users with processors such as Dopod 818 with a main frequency of 416MHz often install CPU frequency adjustment software to reduce the main frequency at certain times to extend battery life. Therefore, the processor is also a large power consumer of mobile phones.

　　Network communication We know that mobile phone batteries often have two indicators, one is standby time, and the other is talk time. The talk time is often much shorter than the standby time. The main reason is that when the mobile phone communicates directly with the network, the transmission power of the mobile phone will be greatly increased. This kind of high-power transmission is not only during a call, sending text messages or It also happens when surfing the Internet through GpRS, so if there are many text messages or the Internet takes a long time, the battery life will be greatly shortened. However, this also inevitably consumes power.
