An issue I've had with my Macbook is that after charging from a non-Apple USB-C power source, the battery life on the system drops through the floor, especially when the system is in sleep state.
Before charging with a non-Apple USB-C source? Starting with a full battery, the system can sleep for at least a week without running the battery completely down.
After charging with a non-Apple USB-C source? Starting with a full battery, the system makes it for 1-2 days sleeping before the battery is totally discharged.
I can restore this to the original state with a PRAM + SMC reset, but that's a pretty big annoyance. And I've tested with a completely clean system without any 3rd party software at all in order to validate this pattern. Something is definitely screwy about charging a Macbook with a non-OEM USB-C power source.
- chaostheory 9y agoWhat brand is your USB-C power source? I've been using a Dell USB-C docking station for a few months now and I don't have this problem with my new Macbook.
- sithadmin 9y agoI've tried a bunch. Anker (AC and battery packs), Aukey, Lenovo, Google (both for Nexus portables and Pixel devices), and Finsix Dart.

- mjevans 9y agoMaybe Apple has an update to the firmware and/or software which resolves that issue. In my opinion, tolerable behavior includes: * Not charging at all (should indicate incompatible or disconnected cable) * Charging (at any speed) only while off/asleep. * Charging, but in some slow mode. * Charging "quickly". Any other behavior sounds like at minimum a software defect, and at worst a non-correctable hardware defect.
