I needed to replace my logic board as the original one had issues (https://developer.apple.com/forums/threa…) and was successful in doing so. I used my MBP for a couple months post install and it worked great. Just recently, the battery life has been nonexistent and needs to be plugged in via USB-C or the laptop will shutdown. coconutbattery reports: Current Charge: 0 mAhFull charge capacity: 208 mAhDesign capacity: 3.1%Cycle count: 152macOS Battery status: Poor I double checked the contacts from the logic board to the battery controller and it looks ok to me. I can confirm that the battery isn’t charging since I checked it with a multimeter and it showed around 2V. My suspicion is that the problem is with the (new) logic board – anyone else think so too?
