Is my battery life indicator accurate?
The battery level indicator in the app is completely wrong. Many customers are seeing battery levels around 60% on new Iotas right out of the box, but in reality they are around 100% battery level. We are patching the software as we speak to make sure it accurately reports the battery level.
TL;DR: It's not accurate right now, we need to test it more to figure out things like what voltage the battery runs out at. We'll be addressing battery reporting in a future patch.
