Wireless Charging

Last week I got new Lumia 925. I have now used the phone three days. I bought the charging shell (CC-3065) and a table and car chargers (DT-900, CR-200). Inserted the shell to the phone, and put the phone on the DT-900 charger plate. The white led illuminated in the plate as supposed and stayed on as long as the phone was on the plate. But the phone itself did not respond with a beep or anything (did not charge at all during the night). Applying some pressure to the phone from the sides helped occasionally (phone actually started to charge) but after couple of seconds or tens of seconds it stopped charging. The charger did not show any error signals. The same thing happens with the car charger (occasionally starts charging and stops charging during a drive). I did some tests with another identical 925 by switching the same 3065 shell to another phone. The results was that everything worked fine. So, there seems to be a problem with my phone. I took it to service today for further inspections. Let's see what they find. Anyone else have similar problem?
 
To reply to myself... the phone got serviced and finally the phone was replaced with a new one (back panel of the phone was wrongly placed in the aluminium frame). Now the new phone works perfectly with the charging cover.
 
Why bother leaving it on the charger overnight? I lose 1-2% in the morning letting the phone idle off the charger. It could easily be fully charged in 5-10 minutes after I wake up.
 
Bought my wireless cover on eBay paid $20 for a new red man of steel edition.Looking for a plate now.
