Overall, feels its a lousy phone:
Cons:
- Battery life is very, very weak. Continuous usage of the phone gets me 2 hours plus of usage before it dies. I had 3 Lumia 920s, all act the same way.
- The stupid thing about the phone is that when charging, using any application will negate any charging and use up more juice than what is being charged! I face this with all so called windows 8 optimized apps.
- The phone heats itself up very, very hot with maybe a continuous usage of 10 minutes or less till I have to put it down for a while.
- I feel most of the applications (WeChat, Skype, Whatsapp) launches rather slowly, especially Microsoft's own Skype which takes a very long time to launch or even resume!
Yes, I tried everything:
- Hard resetting each of the phones
- No background apps activated
- Everything off (Wifi, NFC, Location, Bluetooth, etc)
- Only Windows 8 phone apps downloaded
- 4 Live tiles active (I removed everything else)
