[citation][nom]back_by_demand[/nom]The CPU is not the factor in draining battery life, it is the 4G connection.If you temporarily disable the 4G and rely on the standard connections it's battery life jump way up with the best in the market.http://www.goodandevo.net/2010/05/ [...] -life.htmlThe main factors in killing the battery are screen and transmissions.[/citation]
Actually, don't be narrow on the Evo. I NEVER use 4G, not in my area, and my battery life stinks. It's radios in general. Leaving on 3G for 8 hours leave me at 20% now. GPS on too? 8 Hours is death. Turning off all radios except phone... 8 hours = 90% + ...
And while the CPU may not eat lots of battery, we'd have to assume new devices are coming with all these antennas too and will eat power just as radically without some better management.
I'd really like my phone to be able to come on, check for a connection on 3G, sync data and then turn if back off for an hour or two instead of the always on or always off scenario. I know there are apps that can do it, but meh, it should have been a default feature.
