After moving on, the magic remains. It is fluid, responsive, the HD screen is superb. Moreover, it is possible to adjust color intensity in a dedicated menu, like the white balance. So everyone is free to adjust the screen to your preference.
I tried a number of games, and all passed without any concern, not the slightest lag, not any slowdown, even on larger games Store. It is interesting to note that more and more games and applications are available on Windows Phone, and personally I have everything I need.
In terms of functionality, I am particularly delighted to wireless charging. I have in my possession a GPS support with this feature and NFC (Nokia CR-201), and when I put my phone in its holder, it automatically launches HERE Drive + application (free GPS and offline) while reloading. Tested on very long journeys, the phone does not flinch a bit.
Autonomy is also particularly good, I charge my phone every night but more for safety than necessity, I have generally between 40% and 60% fairly steady despite my battery usage.
In short, I am extremely satisfied with the Lumia 830, I highly recommend. The price / quality ratio is excellent, it is good in all areas, and he knows to get noticed by its elegance. You will not be disappointed by this smartphone.
