#ALDENTE PRO MAC FULL#

P/s: The reason I don’t necessarily have to live with 80% charge is because the MBP 14' is so efficient, even with M1 Max 32-core GPU. Will submit a feedback and perhaps invoke the popularity of AlDente to make the case. I just need a toggle for enabling/disabling charging - and I am currently using AlDente Pro to do so. This is in contrast to my 16' i9 which was plugged in all the time, in which case OBC worked very well. I have had an erratic/irregular plug-in schedule since I switched to the MBP 14', and as a result Optimised Battery Charging (OBC) does not work well (or perhaps even at all). My MBA charges to 100% even though I use it on battery for about 10 minutes each day.

I wish there was an option that said something like Charge to 80% Until I Tell You Otherwise. And since you don’t need it to be fully charged when you’re asleep, there’s no practical downside to this slower charging. The idea is that by charging more slowly after the 80% point, it will (hopefully) extend the battery’s useful life. For example, if your usage history says you remove it from the charger at 8:00am every morning, it might try to reach 100% at 5:30am, even though a traditional constant-voltage charger might be able to bring it to 100% at 2:00am. Then instead of doing constant-voltage at a fixed voltage, it will dynamically select voltages so it will reach 100% shortly before it thinks you will remove the device from the charger. It uses constant current charging until the battery’s charge reaches about 80%. Which is why you will see a battery rapidly charge up to a point and then take much longer to complete the charge.Īpple’s optimized battery charging is a variation on this. It is common for modern chargers to use constant-current charging until the charger’s voltage reaches some threshold amount and then switch over to constant voltage until the battery is fully charged. If the constant voltage is higher than the fully-charged voltage, then there still needs to be monitoring circuitry so it can shut off when the battery is full. Once the internal voltage equals the charger’s voltage, the current will go to zero and charging will stop.

If the constant voltage equals the battery’s fully-charged voltage, the charger can remain in this state indefinitely. As the battery fills up (and its internal voltage increases), the voltage difference (between the battery and charger) shrinks, causing the amount of current to go down, slowing the rate of charging. So it needs to measure the battery’s voltage and switch off when it is full.Ĭonstant voltage charging means that the charger supplies a fixed voltage to the battery. The charger needs good voltage monitoring circuitry, because a constant-current circuit can push a battery’s voltage beyond its rated limits, which can result in catastrophic failure. But as the battery approaches full, the high voltages necessary to maintain the constant current will cause the battery to get hot and can cause the chemistry to break down faster, shortening the battery life. As the battery fills up (and its internal voltage increases), the charger increases the supplied voltage in order to keep the current flow constant. Technically, these two phases are “constant current” and “constant voltage”.Ĭonstant current charging means that the charger tries to supply a fixed amount of current (some number of milliamps) to the battery. They do a rapid charge up to some point and then slow down the rate until the battery is full. Slow (“trickle”) charging can extend a battery’s life, but of course, at the expense of taking longer to charge.īattery chargers these days tend to implement a hybrid approach.

Optimized battery charging is based on the fact that rapidly charging a Lithium Ion cell when it is approaching full tends to result in shortened battery life. Optimized battery charging doesn’t mean it never charges beyond 80% until some crystal ball says you will need more than 80% power in your next session.
