hi there guys, am currently looking at either this or the 9900 but there is only one concern, the battery life...

my concern is that because I do tend to drift between areas with a massive variation in signal strength, so the main concern is that it will drain the battery while it attempts to search for data connections, whats it like on this phone?

am currently on android and the battery life sucks as it barely lasts a day, will there be massive drainage when fluctuating between data connections?

thanks in advance...
