How to get Longer iPhone 3G Battery Life

So you've finally got that spiffy new iPhone 3G. You've waited for a long time for 3G speed, location services, and those really cool iPhone third-party applications and now you're happy. What? You're upset with the battery life?

This is the most common complaint I've heard from the lucky folks who have the 3G iPhone: with some usage, by the end of the day, their battery is almost dead or dead. And, there's no way to swap the battery with a fresh one to fix this problem.

So what's going on? Why did my previous iPhone get such great battery life and my brand spankin' new iPhone gets lousy battery life? The answer is quite simple, and I might add, it's just as it should be: 3G sucks power.

A study done last year by tech website AnandTech showed the actual life of a battery from a original iPhone (edge) vs. a Samsung Blackjack on a 3G network. Their conclusions were as follows:

• 3G is faster but at the price of higher power consumption
• 3G gave about 25% less battery life compared to edge in standard web browsing
• Wifi gave the best battery life compared to 3G and Edge
• Leaving 3G enabled during talk time had the biggest impact: a 52% reduction on battery life

So why is there such shock from folks that the iPhone 3G has such a short battery life? It's probably because the previous iPhone on Edge had such great battery life. But let's remember that Edge has been around for a while and many companies have "mature" chipsets that are low power compared to 3G chipsets. Remember, one of the reasons 3G was not in the original iPhone, according to Steve Jobs, was that the chip set was too big and it ate batteries for dinner.
