past 2-4 days.... my nexus just dies suddenly with the battery drained. checking history with system panel shows that the cpu usage just suddenly shoots up to 100%! and i dont know what app is causing it.
just updated locale and extended controls + a lot of other apps. but my main main suspects are locale and extended controls (since EC posted that they are having problems with the update on the nexus)
any ideas? any other apps i could use to target and isolate the rogue app that drains my battery?
get a task manager and see ?
also, it may just be time for a new battery. ebay. $13 shipped, 2400 mah

System Panel HAS a history, and you can see which apps are using CPU, so have you done that? Is the phone getting hot? It would if the CPU was running 100%. And even at that, it wouldn't immediately die, I've never exactly tried to see how long 100% cpu utilization takes to drain the battery but I'd have to guess it's at least 2-3 hours.

seems fine at first then when i notice its hot... it is already about to restart. couldnt even get to check the app usage on system panel. after reboot... the app usage in system panel goes away. just checked now.. nothing is eating the battery up according to system panel.
guess the rogue app just turns on and eats up all the juice at some point in time. weird.

Do you have SetCPU or anything else enabled with a performance-oriented governor or similar? That would likely keep the CPU pegged at the max without really doing anything.
Try disabling as many applications as you can until you can pinpoint which one is misbehaving.
Same Problem Here
My phone is experiencing atrocious battery life, and so is a friend of mine's. We are both on FRG83D, and it seems to have been the trigger for the problem. He is on AT&T and I am on T-Mo. My wife also has an N1 on FRG83D on T-Mo, but her phone is not having the problem. Her phone is set up very Vanilla, my friend and I have more system altering stuff on ours but nothing too wild, and none of the phones have ever been rooted. The two problem phones both use Launcher Pro and Extended Controls, I am not sure what else we have in common in our apps. I installed System Panel today to try and figure out what is happening, but I still can't find an obvious culprit. While the phone is sitting on the dock charging the CPU seems to be idling under 10% and when I pock it up and look at System Panel you can watch the CPU spike to the upper ranges if you scroll the screen but otherwise it is idling under 10%. The display is always the highest on battery usage and the worst app shows as System Panel, but that is basically what I expect to see. I am ready to start removing apps to see if I can get it back to normal unless anyone has an idea of how to better diagnose the issue.
I had this issue a while ago. "system" was taking up all my CPU, and I couldn't find any details about what was really causing the problem. I couldn't remember how I finally found out about the problem (I think I spent a night reading the logcat to see what was wrong). I couldn't even use the phone, it became horribly sluggish, and battery went flat in mere hours. Turns out, I had a bad picture or two in my SD Card, and the media indexer went in a loop trying to interpret the files. For some weird reasons, the same files got Windows Explorer "confused" too.
Try to remove or format your SD card and see if it's doing the same. I know it's more of an anecdote than a real known issue, but it won't hurt trying
oh wow i was hoping someone was having the same problem... left it overnight unplugged so far so good. now im really beginning to think its extended controls. took out the widget and replaced it with the stock one for now.
IDLING at 10% CPU usage??? Mine idle at 0% if nothing is active. Average 3% over time.
You guys should watch and see what's using hte most CPU, SystemPanel can do it if you look at the history (free for a week or 10 days or something, or buy it to keep the function), but also look at Spare Parts, you can install it from the market. It gives you visibility to a few more Android settings/info menus which you can see which apps are keeping the system awake etc, it can help pinpoint what's going on.
Something very bad is happening. When you all figure it out, report back.
When I look at system panel the little CPU circle graph stays at 100% for the most part. I don't understand if its accurate.

Do you have the app 'Extended Control' installed? The last update is very buggy and is causing bad battery life and broke the camera app on the N1. Check comments on the market. They are working on a fix.

Looks like Extended Controls
I did some testing and Extended Controls does appear to be the culprit. Dev seems to be aware, hopefully they get it sorted.
Edit-Overnight and battery life is back to normal with Extended Controls uninstalled. I didn't suspect it at first because they had already released an update after FRG83D, but apparently it was broken worse than they knew. I hope they fix it soon, I like the app.

It obviously should not sit at 100%, look and see what app is using CPU, it ain't rocket science.. Mine idles around 3% with my apps, mainly K9 and Tasker, weather etc..
Step 1: Call HTC's exclusive Nexus One Phone number
1-888-216-4736
Step 2: Tell the rep your battery isn't holding charge. (Possibly tell him your earphones blew as well, if you lost them like I did )
Step 3: Wait 3 days for the battery (and headphones?) to make it to your door.
You don't even have to ship your old battery back!
Step 4: ???
Step 5: PROFIT!
Hey guys just wondering what are the best settings? Sorry if this a repeat post, ive tried searching but cant find anything. Im still losing like 5-6% an hour if an hour at all.
Sent from my X10i using XDA App
If you're losing 5-6% an hour, I would look into other saving options. I was always a setcpu user to set profiles, but I am having no problems on my x10. I would think you have something else going on, ie too many widgets, bad signal strength, too many things running, highest brightness.
Look at battery stats to see what's consuming the most of your battery.
Otherwise, the most improvement you can make with setcpu, is making a screen off profile and reducing clock to about 50%.

Could you possibly give me some optimal settings for powersave?

Probably a bad App or widget preventing your phone from sleeping... are you getting this level of drain when you're not using the phone?
You should check apps/ and widgets which access the internet to update.. check them one at a time by removing them, or turning the update off..
when in standby you should be losing around 1-2% an hour.
The other thing that causes significant drain is 3G/GPRS IF.. you are on the edge of a coverage area - my house is mainly on GPRS, but occasionally I get 3G/HSDPA.. and this constant flipping between data types knackers the battery so I've set mine to GPRS only when at home.
Cheers.
I have no live widgets just shortcuts and the digital clock. Ive turned of 3g now for some reason when i have my sim card which is not used a lot apart from internet use i have good battery lasting me all day.

Usually when i check the history of my battery consumption the display takes the biggest chunk (abt 70%).
Recently i have started to notice that cellphone standby and phone idle take 20% and 15% respectively. Is this normal ?
I have no CPU issue or any syncing issues. Normally i have syncing, WiFi and 3g turned off when the phone is not in use or when i sleep.

Ofc it's normal if you've been using the phone less so the screen is on for a lower % of the time and doesn't use the battery as much. And the fact that this has recently started to happen suggests that as the device isn't so new anymore you are playing less with it

If you set the backlight to Auto ... it would be the case.
For me .. by just setting the display to lowest backlight setting .... the power consumption for display drops to about 35%.
I searched alot actually but either I searched wrong or there just isnt anything about it - is there a widged or app or something that shows how many mA the phone is draining? I see this written on dev's rom posts but I dont know how to measure it and how to check for it. I guess its something easy but I cant finnd it
currentwidget
free from market
you can get a transparent version by looking in the general Android Themes and Apps section, and looking in the transparent widgets thread
(not HD2 section, just general Android Themes and Apps
Battery current widget is also good.

Sorry, that's battery monitor widget, not current. It seems to work fine as well.

Thank you!
However I am getting ~300mA drainage when I turn on the phone w/o doing anything. How do they get 6mA ??? And how to check how much it is when the phone is sleeping ?
The battery monitor widget has a history you can watch, other than that I'm not sure.

You can set CurrentWidget to update every 60 seconds. Leave the screen off for more than a minute, then check it as soon as you turn the phone back on

Same with Battery Monitor Widget, actually defaults to refresh data every 60 seconds and save history every 5 minutes, giving you average consumption and much lower battery usage! Which is quite important for such tool, isn't it?
Other than test I've just run some tests and BMW consumes less when set with the same settings! See screen-shot!
Funny one.
I think that maybe these monitoring tools can be the issue of these high drainage things. lol
I had my battery monitoring tool set to 60sec and write it to a log on the sd-card.
Waking up the card and writing to it might might cause these higher values.
Trying to set them to 5 to 10 minutes at this moment to check this theory.

AH wondering the same too
One sure thing at one minute it will keep your phone waking-up all the time... then depends for how long...
On my various tests I always noticed draining pikes at very irregular intervals suggesting another app is also consuming... So I usually end-up setting plane mode to ensure nothing should consume and should get a steady 2 or 3 mA!
Now I'm trying Process Monitor Widget to see who's actually consuming the battery... but the app is still in beta and not yet linked to Battery Monitor Widget... waiting for that!
My last test shows pikes of activities every 30-45 minutes (?), whereas battery shows drainage pikes every 4 to 7 minutes (???)! Still searching...
In there various HTC and Google background process are actives... not sure to what extent yet.
Now testing, same setup and plane mode...
If you're running NAND it's probably the 60mA bug you're seeing --- any Notification (Call/SMS/MMS/Email) will draw 60mA until read.
No high drainage

Base on you comment I decided to start testing 2 of those tools: Battery & Process Monitor Widget from the Market.
Phone was in plane mode and apps where recording every minute for 3 hours.
In the first-screen shot you can see drain pikes every 4 minutes (3 to 4) or so... at 6:58, 7:03, 7:07, 7:13, 7:17, 7:20...
You can look at CPU utilization, on other screen-shots, total time shows how much CPU was used during recording per application.
Even thouh the system is in plane mode and there's nothing to run, you can see the Android system running who knows what every 3-5 minutes or so...
I found some explanations with 2 background processes doing who knows what too
For the others it's still a mystery to me. But sure enough some of the drain is due to the monitoring tools...
The 3.48s consumed by the battery monitor is pretty good over a 3 hours recording...
So I will make 2 further tests:
- first with only battery monitoring...
- second monitoring also processes but every 5 minutes

I got similar issues with a previous NAND build, that was awful... 50mA minimum in plane mode!?
THen I switch to MDJ's build... see previous post, very good now

Gonna switch to MDJ tonight myself, I've managed to find fixes for everything but the 60mA drain and I'm too anal about performance/battery to let it go any more. Time to switch, unfortunately.
Battery Monitor Widget and Process Monitor Widget
Back again with some more tests!
It turns out that both those widgets don't seem to impact battery drain, at least not in a noticeable manner.
3 tests in plane mode:
Test 1: BMW alone, 1 minute logging interval... steady 2mA!
Test 2: BMW+PMW, 1 minute logging interval... steady 2mA!
Test 3: BMW 1 minute, PMW 10 seconds, steady 2mA!
In all tests phone goes in deep-sleep mode as usual!
I have attached a few screen-shot of test 2
Screen-shot 11 shows CPU frequency during test 2, starting/ending with screen-on interactive, with 2 peaks in between when I switched screen on to visually check mA.
This showed me that the app I'm using to set CPU max frequency to 245MHz during screen-off is not working
My p3100 battery is not lasting more than 7hrs after jellybean update..earlier it use to last more than 20 hrs...i dunno wat is happening...yesterday the battery was fully drained so i plugged in the charger but within an hour it showed battery full so i unplugged it and after 1hr of use it again showed low battery so i switched it off n turned it on then after that it took around 4hrs to get charged...n from then the battery is not lasting more than 7to max 8 hrs that too with minimal useage..help me guyzz wat to do ???

I'm on taiwan 4.1.1 stock
same problem here, i am stock OTA 4.1.1 (india)
download CPU spy to check and make sure it's still going into Deep Sleep when the screen is off.
Also if your rooted use No Frills CPU (or any other CPU tuner type app) and change the governor from interactive to hotplug, hotplug disables one of the CPU cores when not needed thereby saving battery.
Even for me as well and so many issues so many things missing in the update like
1.Screen capture app is missing.
2.Lock screen is stock in portrait not turning to landscape unable to solve it.
3.Battery is draining so fastly as compared to before.
4.All the apps not responding instantly it is taking time to respond and even i need to reopen it as it is not opening for long time
5.Main thing is Notification bar is too small compared to before and unable to see signal info properly
6.And the home screen seems more crispy i didn't like it at all
and finally before it looks like a tablet now it look like a phone in considering with the notification bar and typical buttons like home screen......

Daniel, it is going into deep sleep.. It's driving me crazy the way it still uses up battery..Also like said by others,notification bar is too small..Can not read anything on it (battery percentage, wi-fi signal, notifications..)..Any other ideas?
I saw massive drain after I installed the latest Samsung push service update. I unistalled the update and everything back to normal.
