I sometimes have the problem, that it doesn't wake up from deep sleep. Currently I have that effect and plugged in the device to my computer.
Is there any way to further analyze this in the serial monitor?
Battery should be enough, about 90% power left (4000mAh LiPo battery)

More detail required.
Timed deep sleep or external wake up?
How have you wired for deep sleep?
Code used?

Hi
How does your GPIO 0 and 2 are connected?
According to
https://www.codeproject.com/articles/1152971/running-a-standalone-esp-and-returning-from-deep :
"The GPIO0 and GPIO2 should be connected to VCC with a 4.7k resistor in the middle. This is to prevent a so-called 'zombie-mode', in which the ESP8266-12 has trouble waking up from deep sleep."
