Help Battery usage?

Riddle me this: when I look at battery usage and it gives an amount of "time on battery", is that amount of time defined as how long, for the given charge, I have had the screen on and the phone in use? Or.does it also calculate.the amount.of.time the phone has been on standby, not.playing music or runninng, in my pocket?


Thanks!

It also counts standby time. Should be pretty much just elapsed time since you unplugged it*.

*froyo started counting strictly from unplug time, charge it from 50% to 52%, unplug, and it resets, starts counting unplugged from there. Gingerbread it only counts as unplugged if it was charged to like 95 or 100%. if you charged from 50% to 52% your unplugged time still remains as the last time you unplugged it from charging fully.

I noticed that sometimes when I restart my phone, the battery use resets to 0h 0sec and sometimes it doesn't. Is that also related to the % of charge remaining?
 
Well, thanks for the clarification. I'm actually a little bummed. I switched from an iPhone and having separate standby and usage amounts, so I jumped the gun this morning when I saw 2+ hours of "time on battery" and had only used 10%. Oh well! I ended up getting a pretty good run (a good 6-7 hours of actual usage) with it today running cellular data off and on, checking email, surfing, navigating for 25-30 mins and consistent texting/phone calls.
 
I hate how it shows on my HTC Inspire that when you make a phone call, the dialer then takes up a lot of the battery life. Either it really is, or it is just a glitch.

Yeah, that irks me. I saw in another thread where someone basically said it was a glitch. He said that, essentially, what it's doing is, the first time you open the phone, or maybe it's the first time you make a phone call, the dialer/phone continues to ping, or bounce signal off of the local towers.. Now, tell me that doesn't drain juice.. This seems different to me than the phone's mobile network simply being on. It's like the dialer/phone, specifically, is constantly communicating with the network/towers on its own. If I understand correctly, it's like this process causes it to pull double-duty, hence the 18%-20% you see it pulling when you look at battery usage.. Someone correct me if I'm wrong, that's just my limited understanding...
 
I think it's just the battery use screen is so wonky and incorrect, when I was running stock rom I didn't notice any type of battery drain serious enough that dialer should be above display, if it was actually happening you'd know, I got way better battery life the 2 weeks I ran the htc gb update than what I got on htc froyo.

I think maybe inspire users were somewhat used to a pretty accurate battery use screen we had on froyo and not liking the somewhat borked one on GB. It's way more borked than that on a lot of phones/roms. On cyanogenmod I can have wifi and cell standby showing like 40% each and display only at like 6% even though I have 2 hours of display-on time.
 
I don't really pay too much attention to the numbers on the battery-use screen since the bottom-line is okay.
My battery life has improved since the update started giving all the weird numbers.
 
This is a little off-topic, but it still deals with battery life:
JuicePlotter comes with a neat little widget that estimates the amount of battery life your phone has left. I find it to be pretty accurate, even though it seems as it overshoots a bit sometimes, but I've never bothered to time it.
 
I have the lowest backlight option and it shows 75% of battery drain is from the screen. Even new phones with larger batteries and dual cores suffer because of the SuperAMOLED screen taking up your battery life.
