Thank you very much everyone for your time and response.
I was charging only for 15 mins as the battery percentage is showing 100% within 15 mins. Even I found it odd. Thanks for pointing out that It might be showing battery 100% even when it isn't. I will keep it connected for 6-7 hours and test it again.

Re: M5Paper EPD power consumption

Sorry to deviate a bit from the current discussion. Do you guys also have a battery life of around 10 mins? I just received my M5Paper and it is of no use as "e-ink" display if it can't last a day with a full charge. Thank you very much in advance.

I have two M5Papers and both of them have horrible battery life. I get max 10 min battery runtime after 100% charge, even when I am not using it at all. Is this problem consistent with all the units or just mine??
