So I tried to add my little review this morning but I see it did not post so I will try again.
The screen, while good, isn't really that great. It might be software but the rendering makes everything seem very fuzzy. Put side by side with my OnePlus Xs 1080p AMOLED it's easy to see that it is not the best. For the price I'll take it though.
The battery is abysmal. I have both phones with me right now and my OPX that I am actually using with a SIM is at 74%. I've been texting, watched some youtube and listened to a podcast in the car. The Lumia wasnt even turned on until I got to the office and all I've done is check for app updates and its at 78%. Like that's not gonna make it a day.
The phone itself is also quite slow. I really wouldnt describe it as fast, smooth, or snappy. It's slower and more laggy than ANY android phone I've used in recent memory. I'm not sure how people think this phone is fast or pleasant at all. It's also buggy af.
The camera is alright. It punches above its weight for sure. Not a great camera by any means but at this price it could be a lot worse.
The design is also ok. Good to hold and very light. However the polycarbonate back feels and looks cheap. You can also press it in because there is a gap between it and the battery and I find this very annoying. Ordered a Mozo wood cover to rectify this.
Finally, it is a great phone for talking to other humans. The actual phoning of people is very good. I like the dialer UI on call display. The earpiece is also very loud and clear. This is the best part of the phone so far.
Don't consider my eyesight to be the greatest yet really enjoying the display, superior to my 830 me thinks... Was surprised to see the same screen flicker/flashing issue that's present on my 830, only the 650 appears to be much worse, phones are running builds .449 & .448 respectively.
A bit early for me to tell but battery appears to be doing quite well and better than I thought, went 17-18+ hours the second day fiddling with it like crazy setting it up, tweaking, etc, ended up w/40% (or there abouts) before putting it on charge. I noticed with both my Windows phones that the first 15-20% gets eatin' up quite fast then afterwards it seems to stabilize.
While it is no powerhouse it is a tad faster and more consistent than my 830, I blame the OS for them both being the way they are and I went in knowing we'd probably experience same or similar experiences between the two.
Actually impressed w/camera under daylight conditions, nigh time or darker situations not so much. There are some sacrifices since it doesn't come equipped with OIS.
The fit on my was good and if left naked, I'd be too light and a tad, shall we say, not the right fit for my hands, adorned it with an Otterbox Symmetry and now its perfect for me... Really do like the looks in its birthday suit but know that is not a good combo for my type of work.
