In flexicharging setting in my Acer ALG laptop, i chose the "Charge the battery when under 70%, stopping at 80% " setting, which i thought meant that if i keep it plugged in, and my battery is at 60, it will charge to 80 and stop charging at 80 until it again reaches lower than 70% but in reality it just stays at 80%, isnt that bad for the battery? Also there is a custom setting where i can choose "start charging when battery is under ___" and similarly with " Stop charging when battery reaches___", so does it work with the same logic that my current chosen option uses(which i dont get)? I want to know if its possible to keep laptop plugged so that it reaches 80% but discharges to like 50% and then automatically starts charging again, so is that possible or not?

    Hi, I don't recommend using Acer's Optimizer and Battery 80% charge limiter features in Windows11, these Acer programs are poorly written, hang a lot and interfere with Windows power management (Modern Standby) and automatic updating (Check for updates). Limiting battery charging will do nothing for longevity of a Li-Ion laptop battery that is an internet ruse and Acer no longer includes this in the latest versions. Just keep the power adapter plugged in 24/7 and the battery fully charged to 100% at all times and a high quality battery will last 1,000 full charge cycles or 4-5 years, limiting charging to 80% will increase your charge cycles and probably reduce the battery lifespan instead of increasing it. Don't worry about overcharging the battery either as Li-Ion batteries come with Smart chips that divert the adapter power after the battery charge reaches 99.9% 😉

    Yes, if you set your Acer ALG laptop's smart charge to 80%, it will likely start discharging when the battery reaches 80% and is plugged in. This is because the "smart charge" feature, also known as "Optimized Battery Charging" in some Acer models, is designed to limit charging to 80% to extend the battery's lifespan, especially when the laptop is frequently used while plugged in. Once the battery reaches the set limit, it will stop charging and may even discharge slightly until it reaches a lower threshold, at which point it will resume charging back to 80%.

    Here's why this happens:
    Reduced Battery Stress:
    Charging a lithium-ion battery to 100% repeatedly can cause it to degrade faster over time.
    Optimal Battery Health:
    Keeping the charge level between 40% and 80% is generally considered optimal for long-term battery health.
    Smart Charge Feature:
    Acer's smart charge feature allows you to set a limit, like 80%, and it will actively manage the charging process to stay within that limit.
    Discharging to Maintain Limit:
    To prevent the battery from staying at 100% for extended periods, the smart charge feature may allow it to discharge slightly before charging back up to the limit.
