Purchased a m5StickV - Fixed in recent firmware update.

[ajb2k3]

@fpsychotic I've got the MK1 as the MKII isn't out yet

[Xeon]

i verified it.
after reaching 70 to 90% full battery the device wont power off.
it just reboots.
after going below this threshold it turns off again normally.

[Thrasher]

Hardmode it with dc-dc stepdown to keep battery outcome always below 70% :))

[Xeon]

Well my battery is now rotten thanks to this.
The battery life is fading very fast.

I want a replacement.
i bought this device to get a task done.
it's going to.

@xeon have you contacted M5Stack support about this? They should be available now

Glad to hear it.

@ajb2k3 So far i managed to program a demo with all the source lying around thanks to our great friends here sharing.

But there are a few source examples i'm looking for.
i'm trying to make a program that tests as many functions and features as possible.

Xeon, I've noticed pretty same problem on my stick-v today.
Whenever I press and hold turn-off button stick reboots instead of turning off.
In my case this happens whenever SD card is plugged in. I've removed it and everything works as intended now

@thrasher
latest Firmware fixes this.
