Charging wattage
My default charger is a 96W charger which is a quick charger. Quick charging as we all know will not be good for the battery. I’ve tried with a 35W charger, however that isn’t sufficiently excessive sufficient to cost the battery and run the machine.
You can’t handle the quantity of present flowing from the charger; that is not how this works. First, present is drawn, not pushed. The gadget (MacBook, iPad, iPhone, and many others.) negotiates with with the charger to ship what it’s asking for. Secondly, the wattage ranking on the charger is the most present output, not what it delivers on a regular basis. Your 96W charger might be outputting simply 3 watts at any time.
Charging to 70/80%
There is no such thing as a want to do that. Overcharging a battery could cause harm to it, however the Apple engineers have already designed, constructed, and calibrated the battery charging in order that it by no means prices to 100% of the battery’s full capability. Plus, with the in-built battery administration options of macOS, you’re not including a lot if something in any respect in the way in which of extended battery life.
Or a whole various to that is to restrict my battery cost to let’s imagine 50% and maintain it all the time plugged in? However I’ve seen that the bottom of the machine alaways stays sizzling, which once more will not be good for the battery.
The bottom stays sizzling for one in every of two causes: continuous activation of the charging circuits as a result of your Mac wasn’t designed to make use of a charging ceiling of fifty% and/otherwise you’re utilizing the machine for what it was designed for. Suffice to say, what you interpret as “sizzling” is effectively inside spec.
TL;DR
I counsel you to not pursue this. Attempting to micromanage your battery on this approach may have deleterious results. Your finest plan of action is to both finances for an eventual battery alternative or maintain you AppleCare+ contract in impact.
