To those who have used WP7, I know that it has Whatsapp and other social-based apps. Does it has Viber as well? I am using an Android devices now but planning to get one WP7 phone for the calls, texting, Viber or Whatsapp, perhaps the occasional FB and browsing, listening to music while waiting at the airport and whatnot. How is the battery life on average use? No need to mention the other aspects like resolution and brightness, and all that shenanigans. All I care about it the battery life, and a bit on the performance on the browser and the said apps. I tried it and WP7 basically is fast and smooth but havent been able to try the apps that are using internet connection to function.

Thanks for the input. I have read about the Whatsapp issues as well, but im sure they will come up with updates as well. As for the battery life, I am looking at one of the higher end models for Nokia, as I prefer Nokia's expertise in hardware Care to share what phone are u using, and average battery life?
