Battery Life: 1st Gen iPhone vs. iPhone 3g

[steve bate]

It all depends on how much mail you're getting, if it's pushing a lot of mail through it's naturally going to drain more battery than fetching.

My 1st gen iphone is about 30% worse off but I attribute most of this reduction to the fact I have Exchange pushing my company email.

If you have your iPhone set to check every 15 minutes, you'd have to receive 96 emails a day to make push waste extra battery.
I'm sure some people get more emails than that, but the vast majority don't, so it works out pretty well for me.

With push you are talking to the server almost constantly (dependant on exchange version) even when in standby in your pocket, so whatever connection you have, (Edge, 3G or Wifi), is being used more or less constantly, hence turning off push means its only connecting when specified (15min or whatever) so you are using a fraction of the power, I found turning push off made a huge difference.

I am wondering if I can get away with push if im only using edge, as thats much less power than 3G or Wifi, but I want to test edge and 3g first, before muddying the waters.

Again, I have push, 3G, location, and WiFi on 100% of the time.
Right now, I'm at 2 hours 14 minutes of usage and 12 hours 34 minutes standby. My battery appears to be just a tick over 50%.
My usage has been texting, email, light web surfing (over both WiFi and 3G) and about 15-20 minutes of game playing. I've made or received only 4 calls, though.

It does seem to deplete quicker than the last iPhone, but I still make it through the day without too much hassle.

judging from your screen shot you seem to have very poor signal...that will drain your battery terribly. Now I am using a 3G and compared to my Gen 1 phone battery is much less (I could almost 1.5 with moderate use) now I get like 15-20 hours. What I have noticed as a battery killer for me was push email and if I left 3G on in areas where there was a very weak 3G signal it devoured battery trying to get a connection...I assume a weak Edge Signal would also suffer this fate.

I think we have to face the facts about 3G...everyone wanted it and while we were expecting battery issues I don't think the majority of people really realized how poor the 3G coverage is from AT&T.
