Its the prices from a few articles I've read, Never use NFC, so not important for me and quick charge ain't needed as its got a 3300 mah battery, my opo battery lasts me 1.5 days, all I do is simply charge at night and I know I can make it through the whole day and have at least 40% battery left. Quick Charge is cool but I don't carry chargers with me, and I feel its being used to compensate battery life instead of just putting a big battery in the phone to begin with. £289 for the 64gb OPO2 is again a steal. Tradeoffs were NFC, QuickCharge, Wireless Charging and High Resolution display. High Res display sucks battery life and ain't really needed above 1080p, Wireless charging is slow and a gimmick, never used it on my N5, Quick Charge isn't needed as its got a huge battery, NFC seems like and over sight but personally won't affect me.
