Does anyone know definitively if it harms battery?
I recently started using one I got for $8.00 on ebay, and I think I may just be paranoid about the battery. I'm running a Nexus 4 (4.4 Purity Rom/Hellscore) and it's about 30% done on lowest screen brightness with about an hour of use after a day of school.

Anyhow, I was just wondering if anyone had any concrete information (aka: I should discontinue use of the charger) or if it's just me being paranoid. Thanks.

Should have no impact.

It's worth noting that wireless chargers are almost always slower than cabled ones, though.

Even if I leave it on the pad?

Yup. Only possible issue is heat; they tend to be warm-running.

Heat is a major enemy of Lithium batteries which is why wireless charging is considered harmful.

That largely comes down to how decent the pad is. Cheap ones get pretty hot. Good ones are perfectly fine.

It does get hot(ter).

I dunno. The N6 is coming out soon anyway, maybe when I get it I'll upgrade to a 16$ charger. Double the price, double the quality, right?

I been charging my Nexus 5 with a cheap wireless charger ($8 on ebay). It works. It does get warm, but now I notice my battery does not last as long as it used to. After a full charge, I have everything turned off like data, wifi, etc so the number 1 battery drainer would be Phone Idle. After 8 hours of sleep I noticed my battery dropped to 78% from 100% overnight. I don't know if I should continue to use wireless charging.
