considering it is a 720p screen and a 410processor i think the battery will suffice...
only 16GB and no external card? The system and app files will take up at least 16GB. There will be no room for pics from the great 8MP camera.
But the whole point of this phone is that it's very light and thin. Incredibly light and thin. So a bigger battery will make it chunkier and heavier. I own the previous version and I found it to be really great for most purposes. I was hoping that the LTE version had more RAM (it does) and a better camera (it doesn't) which for me is the only weak area. The 8MP camera could easily be 13MP and stick out a littel bit. But Blu decided not to do that. Is it as good as a Samsung Galaxy S5 or S6? Of course not. But for $199 is pretty darn good. However, I need a good camera on my phone because it's my main shooter and I have kids. With the 8MP shooter, which is also very slow, I get 1 good picture for every 4 I take (the other 3 come out blurry unless you are in perfect lighting conditions in a bright day outside)
2050mah battery is fine but not great. Samsung Galaxy S6 has 5.1 inches screen with 3 GB ram has 2550mAh battery only. Considering that BLU VIVO AIr has less screen size 4.8'' screen with 2gb Ram and Snapdragon 410. SO the power consumption will not be that bad as ppl think. This will surely come for 1 full day. I liked it
