I have problem with my Cubot One, because baterry stats don't decrease when I using telephone - but when I do reboot battery stats are correct.
I checked anothers custom rooms and problem also exist.
Have you tried installing an app like "Battery HD" to verify whether it's a problem in the UI or a problem in the data fed to the UI ? (In this latter case, the app will also report weird stuff like the battery charge level/voltage increasing or staying the same while the phone is not being charged).
