    Working with my 13inch MBP TB outside on battery last night and it suddenly powers off, trying to awake it shows the dead battery and power indicator onscreen. Took it inside to a power outlet and connected it up and it had the grey screen restoring from hibernation and then back to life showing 62% power remaining.

    Have booked an Apple Store genius bar appt early next week to check things out but not happy that the MBP powered off in the middle of a job with ample charge remaining. Battery checks out ok showing 22 cycles and 96% health.

    Try to do SMC reset, this can bee one time issue due to something corrupted in the SMC configureation.

    Done several SMC resets since getting the MBP with no difference.

    Sounds like it is time to visit the Apple store.

    I was testing different thermal pastes for my late 2016 MBP and I found out that if the temperature of the CPU PECI goes over 89 degrees Celsius the laptop shuts down (both in windows and Mac OS ). You can check the CPU temps with something like istat menus or the intel power gadget or visit the Apple Store :)

    89c? That seems a little low, given the tJunction is 100c.... but I have no way to verify as I can't get the bloody thing past 71c

    I dont recommend it but, if you set the fans to low in windows and run prime95 or open n number of times terminals and type yes (if I am not mistaken), where n is the number of threads your machine has it will shut down when it reaches 89
