For those of you who have received your wireless charger from ATT, have you noticed that your battery doesn't hold its charge as efficiently after being charged wirelessly than after being charged via the wall charger? I charged my phone twice using the charging pad and both times, within 30 minutes of removing it, the battery drained 4-5% without me doing anything on it. I tested to see if the same would happen after using the wall charger and its staying solid at 100% after 30 minutes and one 6 minute phone call.
I want to know if my situation is an isolated one or not so any feedback on your experience with it will be much appreciated.

You guys are paranoid. Wireless induction is no different than the AC coming from your outlet as transformers use wireless induction to change voltages. If you have 12v going through 100 coils and receive that voltage with 50 coils you get 6v on the output.
There isn't two types of electricity being transferred to your phone here...

I know there aren't two different types of electricity being transferred, and in theory both scenarios should discharge at the same rate (with some standard deviation) given the same usage- but that's not what I'm seeing. So I'm curious why the battery is discharging at a far more drastic rate using one method over the other.

but i do think there could be a bug within the battery indicator section of the OS that's affecting things that has anything to do with the battery. this bug could also be why there are inconsistent reports about the battery life of the 920. some ppl are gettin wonder life, others not so wonderful. could some ppl be affected by a bug within the battery indicator that is not letting their battery get the full charge it needs so it's giving off false readings about where the battery charge is? in effect giving them less of a charge than the indicator says? i think that's not that far of a stretch after reading all the concerns. then again this is just speculation, but this speculation does seem to have some merit behind it.

I charged my Black 920 last night using the wall charger instead of the wirless and it is at 93% after being unplugged from charger for 5 hours now.
Yesterday at this time, after charging it with the wireless charger, I was down to about 65%.
Charge time for BOTH was 9 full hours. Coincidence? I don't know but sure is better with wall.
