Just a suggestion.
You guys should try Opera Beta. It doesn't use a lot of battery, plus the interface is slick as fuck (especially the new Speed Dial).
But the best part is Off-Road mode. It saves a lot on mobile data, specially if you guys are not on an unlimited data plan. Just be aware, if you activate Off-Road, some things are different, for example, animated gifs are just static images, javascript is disabled, etc. But it is excellent. According to the software, I used 6.5MB instead of the original 55MB I received, just today. That's over 80% of data savings.
Also, the fast scroll button is neat. Also, they are using WebKit now, so it should render the websites similar to Firefox and Chrome.
Just keep in mind that it is still on Beta. The only I don't like is that it still doesn't have the option to turn on Off-Road automatically when on mobile and turn off Off-Road automatically when in WiFi (like Opera Turbo worked on the old Opera version).
