You're right, we made a mistake. I checked with my partner. Thanks for pointing out, it would be at least 1-1.5 months for 2000mAh. Talk about short selling yourself! E-papers have a slow refresh rate, it takes about 5 seconds to display a completely new image. And considering it takes about 15 seconds to connect and download an image (based on network speed), we get current spikes upto 300-400mA during WiFi transfer. We can expect conservatively a 1-1.5 months life from a 2000mAh battery. The mAh unit enables us to compare batteries easier I believe. Standard LiPo are 3.7V so given a mAh rating its easier to know which will last longer. While for a Wh unit you would have to calculate it.
