Yesterday I limited 3G network usage in an attempt to compaire the 3G iPhone’s battery life with that of my first generation iPhone. Sadly, this did not help battery life. Running on the Edge Network with normal usage still left me with a dead battery by the end of the single day usage.
For todays test I am turning of ‘Push Data’ to see if perhapse this is what is nom nom nom’ing on my iPhone Battery. The goal is to feel confident in the Phones battery by limiting background network usage since they are not needed at all times.
My understanding of the ‘Push’ Feature is fairly limited in that iPhone Direct Push allows your device to receive updates instantly for email and other data from your server. - The ‘other data’ is what I am really concerned about. Could the iPhone or even installed App’s be consuming battery life by sending data up to the servers via 3G while you’re not looking? I think they may.
The second gen iPhone 3G still has the same limited visibility on your battery life, the simple bar indicator, which just doesnt cut it! There are several battery monitors available for jailbroken iPhones via the Installer App, but not in Apples ‘App Store’.
Today I will be using the EDGE network as apposed to the new 3G network available on my Second Gen iPhone, with Data Push turned off, and Location Services off. Hopefully I’ll get better battery life.

mattyohe“My understanding of the ‘Push’ Feature is fairly limited”—Stop there.
“Could the iPhone or even installed App’s be consuming battery life by sending data up to the servers via 3G while you’re not looking?” The answer is no. No apps other than Mail are running in the background.
Push will actually increase battery life in most cases since Mail does not have to poll the network every 15 min for a fetch of email. Any new mail is pushed to the phone. Novel, huh?
However, at some point there will be a tradeoff in a Push vs Pull battle. For example: If for some reason, your synched calendar updates several times in several 15 minute periods over the course of an entire workday, then it might be advantageous to do this in bulk instead of pushed in the moment.
