I know there's all sorts of talk regarding the 3GS battery life, and I just thought I'd go into detail about how I use the phone, and the battery life's I've been seeing. I use the iPod for multiple hours per day, at least 4-5. I'm a programmer and need something to listen to. I text ALOT. I have the unlimited plan, because i'm usually around 1800-2000 per month. I don't use the phone much, maybe 15 minutes per day MAX. I feel like I use the 3G internet very often, in short bursts. Google queries to reach Wikipedia, opening up the Facebook app 10-15 times per day (til they get push), etc. And with that usage, here are my results: On both the first-gen and the 3G phone, I take the phone off of the charger @ 8am, and by 10pm i'd be hitting the 10/20% warnings. On the 3GS, I take the phone off of the charger @ 8am, and a full 48 hours later, I hit the 10/20% warnings, depending on the usage differences. Let me know if you have any other questions regarding my usage, and i'm happy to update the post above.
