The main purpose of the Battery Protection Mode is to prevent overcharging, over-discharging, short-circuiting and overheating of the battery to ensure the safe operation of the battery and equipment.
Battery Protection Mode works by monitoring the battery's SOC and voltage levels in real-time. When the SOC falls below the predetermined threshold, the battery management system (BMS) activates the protection mode. In this mode, the BMS limits the amount of power that can be drawn from the battery, preventing it from being deeply discharged.
It works by limiting the maximum charge of the battery to 85% to extend the battery lifespan. You may be wondering how limiting the battery's capacity helps to increase its lifespan, but the science behind the Protect Battery feature is actually sound.
By reducing charging wear and protecting against high temperatures and voltages, Protect Battery helps maximize battery performance. Whether or not to use Protect Battery depends on whether you prioritize a longer battery lifespan or maximizing your phone's power capacity.
However, the impact of Battery Protection Mode on battery performance is generally minimal, and it's a small price to pay for the added protection and extended lifespan that it provides. In most cases, the BMS is designed to minimize the impact on performance while still providing adequate protection for the battery.
Enabling battery protection mode varies depending on your device and OS. Here are the general steps: Android Devices: Go to Settings > Battery > Battery Saver or Low Power Mode. iOS Devices: Go to Settings > Battery > Low Power Mode. Windows Devices: Go to Settings > System > Power & Sleep > Battery Saver.
