![]() ![]() 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. Preferably on our premium support email address which you can find in the release notes in Setapp.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. If it doesn’t work, please send us a debug file. Please try to reinstall the newest version of AlDente Pro and if it might work again. No, I meant doing an SMC reset when AlDente Pro is uninstalled. That’s why you had to use the Intel Mode on your 2014 MacBook. The Intel Mode uses a different pathway to control the charging behavior of MacBook which is mostly intended for pre Thunderbolt 3 MacBooks since they don’t have the new technical pathways available. So you propose me to install it again, reset the SMC and check how it goes? That happens to me as well in my mid2014 MacBook Pro (yes AlDente works there as well). Even I set limit to 100% before uninstalling. I only did it after remove it because charge limits stills remains set. This is something I was able to do with my 2014 MacBook and Thunderbolt2 dock but not with the new usb-c docks.ĭid you mean desert SMC while still using AlDente to see if it's behavior change? No. I see that it will only have the charge limit capability while what I really want it to been able to discharge the battery while I'm still connected to the dock for external monitors. I don't have a clear idea of the differences. ![]()
