Demystifying the battery killer of mobile phone lithium batteries

Revealing the killer economic term for mobile phone lithium batteries, inflation may be the best way to describe mobile phone battery life. A few years ago, even flagship models such as Samsung Galaxy and Motorola Droid usually only had 1,600 mAh batteries, enough for a full day. Nowadays, flagship models with 3000 mAh battery capacity are everywhere, but it is difficult to meet the battery life of one day unless the so-called power saving mode is adopted. So what caused this situation? Obviously, the mobile processor is the core of the smart phone, it often determines the battery life of the phone. Although processor technology will continue to improve, from 65nm to the current state of the art 28nm process, improved performance and reduced power consumption have been claimed by manufacturers. It is obvious that the smartphone is a hybrid computer device, and the processor's impact on battery life It's just part of the story. For example, the current Android phone with the highest specifications, even if it uses a 28nm process processor, may have a 2K resolution screen of more than 5.5 inches, a high-resolution camera and 3GB of memory. These high-end configurations will undoubtedly consume more power. To give a simple example, the 5.5-inch LG G3 has a 2K screen, which consumes more power than the Sony Xperia Z3. The Xperia Z3 has the same processor, but the screen is 1080P. So, is the high-resolution screen more power efficient? Not necessarily. Screen skills are also very important. For example, the battery life of the Samsung Note4 with a 2K screen is almost the same as that of the 1080P Note3. The key word here is: pixel position. By adding the number of sub-pixels, you can increase the brightness of the screen without consuming power. This is what Samsung and Sony have already done. In Android phones, in addition to Nexus devices running the local system, a large number of OEMs use self-meaning interfaces and a large number of built-in software services in the device. These services often modify background processes and are an important reason for battery consumption. If it is a carrier-customized model, the difficult carrier's built-in applications cannot be ignored. Therefore, a mobile phone with a built-in 3500 mAh battery can theoretically be used for 2-3 days, but due to the above reasons, it may only be able to complete more than one day of battery life, which is very frustrating. As for battery life, considering many things that mobile phone manufacturers have to consider from an industry perspective, they seem to have few things to offer in a short period of time. For customers, it depends not only on battery capacity, but also on processor model, screen technology, system optimization, and software integration, so that it is possible to obtain a more satisfactory product.
