Demystifying the three truths about mobile phone batteries

Revealing three facts about mobile phone batteries For smartphone users, we often worry about the remaining 5% of the phone’s power. We are also trying to find ways to save energy. Even some obsessive-compulsive disorder users will carry a charger, possibly a spare battery, in case they need it. However, we may not really understand smart phone batteries, such as: Fact 1: Your phone battery has never been exposed to water. You may have been deceived by the manufacturer, but that is a white lie. Most devices are not designed to charge or drain the battery, which can cause instability. Generally speaking, the battery of a device can only use 80% of its full capacity. In other words, when we see that the cell phone battery is fully charged, we actually only use 80% of the battery capacity. Fact 2: Batteries and chargers don’t work. There are many reasons not to use cheap batteries and chargers, but safety comes first. When the battery is charged, a short circuit may occur, causing a fire. If the charger does not have enough power, it will send too much current to your phone, causing an instantaneous power surge, causing the phone to overheat and catch fire. Don't you believe it? The next time you hear someone inflate the phone, look at the subtitle and it will say: Cheap chargers are the mastermind. The third stage: the background program is such Apple and Google are very smart companies, they understand that if the smart phone applications are running, they will consume electricity. In fact, the mobile operating systems of these two companies limit their back-end applications. Take apple as an example. Apple only opens 7 API interfaces to background programs, including calls, messages, music, and so on. Only the programs involved in these seven API interface calls can be run in the background, and the rest of the programs can only be stored in the background as a program list, and cannot be run. Regarding Android, it does not provide the same interface as iOS, because Android is an open system. However, in the actual developer model, Android provides options to limit the number of background applications. You can set or disable these options to save power.
