Finally got myself one, in dark blue. From my usage so far, I found it to be responsive and relatively smooth. The back plate is indeed a grease magnet but can be easily cleaned (against my pants or shirt no less, but no visible scratches as of yet). I'd recommend screen protector and case still, to make it more aesthetically durable while in your pocket (of course don't place together with your keys, spare change or lighter!).
Luckily, the power bank I bought does charge up the phone nicely, charge rate about 1A there about (output max 2A), so that settles the incompatibility worry that I had. Screen is amazing too; well, I'm a first-time smartphone owner so I'm easily satisfied.
The phone back is too shiny and glossy, surely easy to be scratch by keys, lighters.
those who have this, how's the batter life looks like? Don't tel me the gsm PAPER SPEC LIFE of 64hr, I want to know the real time normal usage can last one full day anot
Though it isn't conclusive, I have to say the battery life is pretty decent for a phone of this calibre. Yesterday, when I first got it and booted it up for the first time, I got 83% to start with.
After some substantial screen-on time tweaking settings and surfing and downloading stuff on wifi, plus taking some photos to test camera and listening to some music and radio, left with 49% after almost 5.5 hours.
Before I slept, charged it full then turn off screen and wifi, idle more than 12 hours, woke up with 95%. However, all this is without the SIM card actually installed. I believe the idle draw will definitely be slightly higher as it latches on to GSM network.
EDIT [13/6]: I fired up CPU-Z and saw that the chipset listed is MSM8226 (dual-SIM and China models get MSM8228; the rest gets MSM8928). On Wiki, that chipset only has the Cortex-A7 up to 1.2GHz and no LTE connectivity. The clock speed on my set does rev up to 1.6GHz, so I hope my prized LTE connectivity is there too and the chipset shown is actually not what it is!
EDIT [15/6]: Just got a 4G nano-SIM and installed it. The phone does indeed have LTE enabled, so that's a sigh of relief there lol.
