I must say, the DHD has an excellent battery.
What happened there!?!? Looking at that, it appears that you haven't been doing anything with it either... is that right?
Not having a signal or having a weak one doesn't help matters, but that does seem excessive.
What does the previous screen show, the one where it breaks usage down by app?
The battery is piss poor, end off, fact, but i still love my DHD.
Me too, but my battery's never been that bad!
Constantly awake for 6 hours 47 mins? Sheer madness! Though it does dive quite steeply with the screen on.
I wonder whether you have some rogue app running that's trashing the battery but somehow not showing up in the list of what's consuming power. I suggest this because your photo shows that your phone is awake 100% of the time. On mine, it is awake only when the screen is on, give or take an odd bit of other activity.
I seem to remember some advise given here a while back which gave details of a battery/cpu/process monitor which could show how much power each process was consuming. Maybe someone can remember which app that was?
Out of interest is that battery monitor your using built in or an app? I know you can check some of those in the battery settings but not in so much detail.
It must be something to do with phone signal, because when it has no signal or a poor one the phone will try at certain intervals to try and pinpoint a signal. If it does this every 30seconds then it could easily be the cause.
Do you mean the battery use graph?
"menu=>settings=>about phone=>battery use"
Could well be!
I do love the phone but I find the battery life horrendous!
I need to look into why the phone is awake 100% of the time, I didn't realise that particular item should be showing awake all the time??
On the other screen where you can see the % used per item and 57% screen, 10% Android, 10% WiFi etc...
Nothing is showing major usage..
That's the one cheers.
Isnt awake time how long the phone has been on, whether the screen is off or on? Since there is a separate stat for how long the screen has been on the awake time should just be showing that the phone has been on all the way through.
It was my understanding that awake time is the amount of time the phone has been actively doing something, mine shows on and off as it checks emails, updates facebook etc. A large awake time is usually a sign of a rogue app, it definitely shouldn't show anywhere near that much. When the screen has been off and there are no tasks actively running then the phone should go to "sleep".
If there isn't an app showing then I'm a bit confused as to why your phone is awake. There's an option to keep the phone awake while charging but not one for off charge because (obviously) it drains the battery.
I don't really know much about this, but could an app with permission to keep the phone awake be causing the problem, even if it isn't actually doing anything (which could be why it doesn't show in the list)? Just a pure guess though.
List me the apps you have installed. For goodness sake myself and El Presidente have both proven the battery on the DHD is far from as crap as people posting this naff up would have you believe. Over ten hours I can hammer the net, facebook, twitter, take a couple of photos and film for an hour solid (I use DailyRoads Voyager to film most car journeys without charging it). Its more often a case of people ignoring the permissions section prior to downloading from the market just as the would ignore reading an EULA. I
I suspect the screen brightness is too high. Mine does not dive that much when the screen is on.
Secondly, something is trashing your battery because it shouldnt be awake all the time like that. My awake graph vaguely resembles a bar code, due to it only checking for emails every 15 minutes
Didn't mention the apps I'm interested in are the ones found under: SETTINGS>APPLICATIONS>RUNNING SERVICES
Yeah, awake time is when the phone is actively doing something. Up time is the total time it has been running. I think it also shows time off charge somewhere.
I didn't grab a graph of it, but I went to my mother's place without a charger, stayed overnight and then came home. My phone ran for ~30 hours and I had read my book on the phone for over an hour and showed my mother a few things on it. I can't see that there is anything wrong with the battery life.
Yesterday I was busy doing stuff and my phone was just sitting in my pocket with the screen off. After 8 hours my battery had dropped from 100% to 82% (less than 5 minutes of screen on, just standby).
I have over 80 apps installed and leave WiFi on but bluetooth and GPS off most of the time.
OP: Here is a newly developed app from XDA for you to install and find out what it is keeping your phone awake. When you find it please let us know what it is to help the community avoid said app which would be a far more constructive post...thankyou

There is some sort of problem going on here. Mine averages 17 hours, screen on auto, 3g kept turned on. I am an average user, news app, texts, net, e mail.
