Re: Multiple Apps / Battery
Depends.
If apps are using the data connection your battery life will plummet. For example, I've yet to find a good IM program, that keeps up with alerts, and doesn't tax the battery. Programs like contacts and calendar shouldn't negatively affect the battery too much.

Re: Multiple Apps / Battery
Technical related question: Wouldn't empty ram use just as much juice as occupied ram, granted the ram isn't being accessed/processed?
That was always my understanding, and if this is true then dormant programs that aren't running any processes in the background shouldn't matter.

The reason people's phone gets warm is because of the RADIO, not the CPU. Our devices use very little power in PDA-mode. If you have a data connection open, then your battery will die quickly. |

Re: Multiple Apps / Battery
I tend to close any apps I am not currently using.. I guess it is a habit I picked up from having a Mogul.. An opened unused app might not take much battery juice to keep open, but over a day every bit counts..

Re: Multiple Apps / Battery
At work I turn my phone to airplane mode since I have no service anyway. This saves me a ton of battery.
As far as the phone getting warm because of the radio, why does it get warm when I do a large file operation? I'm not saying the radio might not be a cause, but the cpu does get warm as well. |

Also, the resistance is there whether power is being drawn or not, it is the current draw that changes (e.g. P = I^2R) Quote:
Correct on Point 1, I concur on point 2 (I see 60-90 mA MAX when pushing the applications processer extremely hard (with the blacklight OFF), I agree on Point 3. |

Re: Multiple Apps / Battery
I haven't found any IM program I like yet. Oz is the best I've tried, but still leaves much to be desired.
Also, unless you have an intermediate server, leaving connections to AIM or whatever all day WILL drain your battery if they are keeping up on alerts. Every time somebody's status changes, signs on/off, whatever it is going to tell you, which will get your data connection pumping and the CPU ticking.
