The expert called Volgograd the reasons for the rapid discharge of the phone
If the phone began to lose charge faster than usual, do not immediately blame the battery. There may be several reasons, and some of them are not related to battery wear at all.
Lithium-ion batteries lose capacity over time: after several hundred charge-discharge cycles, the device does hold the charge worse. But no less important is the controller of power and habits of the owner. Constant charging to 100%, full discharge "to zero" and connection to the outlet for the night gradually accelerate battery wear.
Messengers, mail and geolocation services continue to work even with the screen turned off. If several resource-intensive programs hang in the background, the charge goes away noticeably faster, although externally it is almost imperceptible.
When the smartphone quickly discharges, heats up or suddenly turns off, you should think about replacing the battery. For most models, the procedure is inexpensive and fast, and the device gets another two to three years of service.
Check the status of the battery on the iPhone is simple: “Settings” → “Battery” → “Battery status”. Maximum capacity below 80% is a signal to be replaced.
There is no universal button on Android. Samsung's battery status is viewed through the Samsung Members app in the diagnostics section. Xiaomi has information in the battery settings, but not on all models. On Huawei, you need to open Settings → Battery → More Battery Settings (or Battery Health) → Maximum Capacity.
To save charge, turn off the voice assistant in the background. Stop constantly searching for Wi-Fi and Bluetooth. It is their work that consumes most of the energy: where there are no familiar networks and devices, the phone continuously scans the ether.
Do not keep your phone on charge all night. A modern gadget takes two hours.
Watch the temperature. Frost and heat are equally harmful, and sharp drops are dangerous for the components of the body: plastic, glass and aluminum become more brittle.
Check what's consuming the battery. The settings show which apps spend the most energy.
The head of the Center for digital expertise of Roskoshestvo Sergey Kuzmenko notes that a quick discharge is not always a verdict on the battery. Another thing, if the battery is swollen, the phone turns off at 20-30% charge or the body is warming at rest: here the settings will not help - the battery has developed a resource, and its replacement will return the device a second life. If after replacing the battery, the symptoms persist, the problem is deeper - the power controller or board is damaged. In this case, repairs are often more expensive than a new smartphone, and you should not delay replacing the device.
