So, does the battery protection function really work? The answer is yes. This function is designed to operate automatically and continuously, providing a safeguard against potential risks and ensuring the battery is properly charged and 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.
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.
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.
Just go to modes and routines, set one that turns off fast charging until your alarm goes off. Then set one that turns on battery protect at the time you go to sleep or plug your phone in, but have battery protect turn off 30 minutes before your alarm goes off so by the time it does, your phone is full.
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.
If you are concerned with squeezing almost every jot of power out of your smartphone, Protect Battery is likely not for you. If you don't mind shelling out the cash for a battery replacement (or a new phone) after two to three years, you can definitely do without the feature.
