I'm trying to get a better feel if i replaced my ole and trusty Atrix 4G with a Moto E. I don't really care about photos, i don't really play games on a mobile phone but my cousisns do, and i give them my Atrix to play, but i'm trying to see if i can get a better battery life. I use my work phone mostly for calls and 3G browsing/VPN, and at mid day i need to start looking for a charger. Would it be such a huge difference to switch from the Tegra 2 (A9 cores) to a Snapdragon 200 (A7 cores) in terms of performance and battery duration? If possible, i wouldn't like to get a decrease in performance (the Atrix is still better than most low- and mid-range phones out there, for shame) especially for gaming, but if i do, i would like it to be the least noticeable drop possible.
