I had both Onyx and Artatech androids. No difference in behavior.

If you look at battery app screenshot carefully there's small blue line under power level. There's also green line(in area that appears thicker). On resized version it's really hard to see there are actually 2 lines. I assume(since there's no legend) that green line is when I had wifi on(pretty short time). Blue line seems to be when the device was awake. Also, even if there was wakelock on the battery usage data would have been collected over that time. Meanwhile it went from 50 to 0.

Logcat? Nah. It didn't show anything out of ordinary when reboots happened. It just stopped sending new messages. As if the power was cut suddenly.

Since some people are not struck with the problems, and I heard stories of people getting good one after 2-3 replacements I expect it's hardware related after all. Probably the percentage of broken devices is lower than it appears to, as people with broken devices tend to complain more than people with working devices praise them. Also some people might recharge before 50% mark, or whatever % the issue would appear for them. They might not be aware of the problem.

For me though this is dealbreaker. About half of the reason I buy ebook readers is long battery charge. If I have to recharge every 3-4 days to keep above 70% then not only my total battery life shortens battery lifespan but also I don't get one of the best benefits of using ebook reader above some LCD device. Reading in full sunlight is nice and all, but I want to go on 7-10 day holiday without taking a charger.
