    Wicked idea but I do shift work and 24hr on call. So can it be disabled if you just want a fast 💯 charge..

    what stress is it going to be under if no current is going to it? power comes through the outlet and not the battery

    Batteries don't like being stored at 100% for extended period of times. But a lot worse effect exists when being stored or discharged too low. It does not like high temperatures nor low temperatures.... And so on...
    Then there is the way Android works. It NEEDS 100%, atleast for some time at regular basis. So avoiding it completely is a really bad idea and you loose in the end due to badly optimized system.
    The optimized charging tries to minimize the long term effect 100% has while (hopefully) still leaving enough time over for background optimizing.

    and you need to prove your points without childish ad hominum attacks.

    let's say I charge my phone battery to 100%, take it out of the phone, and set it somewhere in room temperature for a day.

    this damages the battery?

    A day would be a very short time... Let's talk the whole life time of the phone. All those extra hours laying at 100% can be cut down perhaps 80% or probably more. Take an example of 7 hours a night. 2 years. 2555 hours. Those hours could be cut down to 511 or less. 2555 hours would be approx 106 days on the charger att 100%. I don't know the amount of wear it adds but 106 days surely has a measurable amount of wear. Better with 21 days right?

    My math could have some mistakes... But I hope it was right. 1h over midnight so... [e]1f61c[/e]

    so this information is false:

    2) You can charge your phone to 100% everytime and you can leave it over night plugged at 100% for the whole night. Charging to 100% of what BMS allows doesn't harm your battery AT ALL. In fact number of charging cycles for li-ion batteries is based on DOD which is Depth of discharge e.g. >1000 cycles @ 100% DOD, >2000 cycles @ 90% DOD etc. Depends on a paricular lithium battery, manufacturer etc. And as to leaving phone connected to charger when it's already 100% does NOTHING because BMS disconnects the charger itself, you don't have to do it by unplugging the battery. Lithium battery has to be controled this way or else it blows up (literally). When you have 100% battery and your phone is still connected to the charger, battery is on stand by and your phone use power from charger only. That's why you'll always have 100% battery while plugged.
    3) The moment BMS decides to end charging is usually when current reaches so called CUT OFF value which means battery can no longer take current that is more than e.g 150mA so when your phones charges <150mA for a set period of time, BMS knows it's fully charged and it has to be disconnect or else the voltage can rapidly increase, overloads battery and cause the damage, usually blow-up.
    4) The process of charging li-ion batt goes like this (let's start from full current):
    a) CC (constant current) stage which means the battery takes full current, in this case 4A but frankly it's 3,4-3,6A.
    For 3,3Ah battery it's current around 1,1C, it's perfectly good value for battery life.
    b) when battery reaches certain point of voltage (on Dash I noticed it's around 60-70% approx.), current drops naturally and it keeps going down with increasing voltage
    c) CV (constant voltage) means BMS sets 4,2V (usual value for 100% capacity of lithium cell) and current is going to 0A since your battery is almost charged at this point e.g 4,1V and charger gives 4,2V which is 4,2-4,1V = 0,1V, it allows really low current. But it's important to charge to 100% because last stage lasts long but it gives you significantly more capacity, especially for only 3,3Ah cell. Moreover, this stage is most dangerous because voltage for almost fully charged cell becomes unstable and when it takes current, it'll increase voltage easily and rapidly. That's why cut off current has to work and stops charging when it's time. The process can go a few times e.g. if battery goes >4,2V, the charger disconnects, waits few seconds, lower current from charger and starts charging again. And after e.g. 3 repeates, it ends the charging process for good.
    5) In a nutshell, don't let your battery discharge lower than 10% and it'll keep capacity longer. That's kind of additional way to enhance battery life because BMS itself will never let your battery to discharge to 0% capacity. They can't allow it because number of cycles would be too low and capacity would drop too fast. You can charge to 100% everytime and keep it through the night, it'll do no harm at all. And if you can, you use your phone connected to the charger when battery's full. That way you don't use your battery at all.

    The natural aging process of the battery happens regardless of charger being connected or not. The idea is to hold the battery at a level with slower aging process.

    Android needs 100% and being connected to optimize. The charger being connected at 100% is not harmful by itself. Long term storage effect is a different thing. That is what this function is trying to decrease.

    The most basic stuff to do is to avoid extreme temperatures and deep discharges. And don't avoid 100% like your life depended on it. But other than that try to enjoy your device and don't worry too much.
    The only way to avoid an aging and slowly decreasing battery capacity is to not owning a battery

    so charging your device to full won't do anything to your battery as long as you don't leave it there for 2 months(which no one would do anyway).

    got it..
