I was noticing fast battery drain on my phone, so I checked the standard Android battery stats, and couldn't find anything out of the ordinary. I tried deleting batterystats.bin multiple times, but it didn't seem to have any effect.
Then Distortedloop on #project-voodoo suggested I check if I had any apps installed that were causing my phone to frequently wake up. You can do this by downloading Spare Parts from the Market, clicking Battery History and then selecting 'partial wake usage' from the top dropdown menu. It turns out I had an app installed (Huffington Post) that had kept the phone awake (even though it was supposed to be sleeping in my pocket) for 20 minutes out of the past 4 hours (!). After removing the app, my batterylife seems to have improved a lot
So a tip for everyone: even though the built-in stats don't indicate that a certain program is draining batterylife, you might want to check through Spare Parts.
Good tip ! Thanks !

thanks nice tip..didnt know this
Cheers! Looks like the Facebook app is keeping my SGS awake
Nice one. No issues except in Network usage the app using far the most is just shown as "0" that is the number zero. Anyone know what this is? It FC's if I click on it.
Thanks for the tip! I was also experiencing a faster drain than usual and I couldn't figure out why. Turns out that Huffington Post and Sipdroid were both high on the list, so I've uninstalled HP and turned Sipdroid off when I'm not using it.
Found out about this from the G2 forum
"LED Me Know" is a great app (available from the market) which you can use to make the LED blink for notification ! You can select if you want it to blink for new SMS, gmail, missed calls, etc. Also there's an option to make the trackpad light blink, though I've not tried that myself. Works great on my DZ with stock ROM

if you looking under running apps, this app is a resource hog. i uninstalled it because if uses up battery quite a bit. just my $.02.

I can see it using a few MB of memory, but that's fine, I've got plenty of RAM. I haven't noticed any difference in my battery usage today since I installed it this morning, but I'll keep an eye on it, thanks.

Nor did I, the only thing that I noticed was my LED would flash for no apparent reason even without any notifications. Had to uninstall
There was an update to the program yesterday, with some more new features.

thanks for the heads up, might need to give it another shot
had it for 1 day, and deleted, cuz when i receive sms or email while i sleep, the blink will either wake me up, or it will drain out the battery by the time i wake up (after it blinked for so many hours....)
good concept, good app to be use while i'm awake~

ok, so why not put the phone face down, or in its case or something if you don't want to see the LED flashing ? Another alternative is to turn off the service when you want to go to sleep (just go into the app and select the option to turn it off).
And did you find it to really drain the battery overnight ?
Maybe it's not for you though.
Unfortunately I also had a problem with this app draining the battery. I installed it on my stock T-Mobile G2 and experienced less than a third of my typical battery life today while using it. Not sure if the app itself is causing this or the flashing LED is drawing that much current. I uninstalled it for now.
Hi,
Is there something wrong with my battery? This is the second time it has happened to me .. last time I left it overnight at 45% and when I woke up the phone was off, so I looked in battery usage and saw that it fell to 0 right from ~25%, and today, I was in an international call, and the call cut off and the phone shut down. It wasn't hot at all, I checked.
Is there some bug with the software, or is it a problem with my battery?
Can you check in the setting menu, where the battery is used for? There must be some or one thing, maybe a constantly updating widget, which is faulty, it really take me 1.5 days before my battery is flat with internet on all the time, and 3 days plus with internet off.
On the other hand I had the same with my lg a while ago and after a flash it was OK.
Sometimes these kind of phones behave very unpredictable....

Oh I'm not worried about the battery life, I was putting it through a lot of use.. and I have a lot of widgets updating frequently
My concern is with the sudden drop from ~25% to 0 which has happened twice now
your battery might be wrongly calibrated.Download battery calibrator from market.charge to 100%,click calibrate battery..it should fix your problem

This happened to me few times. The last time I noticed was from ~48% left it overnight (only about 6 hours) and I woke up to find the phone was off. Usually my phone loose about ~25% overnight. Not sure what or who is the culprit. I have flashed few firmwares and none fixed the issue. Currently I'm rooted using Generic World firmware with locked bootloader and removed many bloatwares.

I've this program installed and I'm sure it has not helped with this issue. I see "missing data" when there is a sudden loss of battery.
I´ve also the problem; my arc is not rooted, so there is no chance to calibrate the battery...?
Had it once, took the battery out and in again and it had 20% more again. Then I charged it at home and so far it works fine.

Thank you. I´ve taken out the battery for about 15 minutes and put it in. The percentage is still as before.
Is there another way to reset the batterystats.bin without root?
Well looks like many people are having this issue, either there are a lot of faulty batteries out there, or its a problem with the firmware. I'm leaning towards the latter.
I'm using Rogers 2.3.3, what are you guys using?

I experinced this issue with Singapore generic firmware as well as World Generic (current) firmware. Hence I don't think it could be a specific firmware issue.
Awake
Anyway to find out what or which program kept the phone to stay in awake? As you can see the screenshot, the phone was awake during random times and most of the time without the screen isn't on.
Sorry, no idea,perhaps someone else here can help
For me its probably something like latitude which I set to auto update

"Latitude"? How can I verify that it doesn't affect me
Latitude comes with Google Maps, its basically a location sharing feature. If you press the menu button in google maps you can click on latitude, then menu button again -> settings, and change from 'Detect Automatically' to 'Manual'
If you don't know what it is I doubt you actually have it enabled anyway, so it could be some weather widget maybe?

I checked and my menu reads as "Join Latitude" which means I have not enabled it in the first place (I guess so).
I'm using Beautiful widget for weather service so not sure whether that is the culprit.
I wish there is more visibility for this .
Thanks for your explanations .
Btw I tried the Supercharger script, and it has doubled my battery life

I chose options 1,6,17

I have the very same problem. The phone battery goes from 100% to 66-64 over the night...showing that the Cell standby and Display has drained the most of the %...
I tried using the app called Light Flow in order to control the LED notification colours, seems to have been draining the battery..anyone else experience this?
Yeah I've noticed something causing my cpu to 'wake' more than it should when it should be idle. I've been thinking it might Light Flow, think I'll uninstall it tonight and see how much I lose overnight.
Don't know whether it's been the updates it has been getting or if it's done it all the time, but I know my battery certainly didn't drain this quickly before when idle.

yeah same thing happens to me, in the battery stats Android OS is the main contributor to drain and the CPU Awake time is always pretty high
interesting I havent suffered much noticeable effect on the battery. I juhst crashes every time i reboot the phone.
I disabled it earlier because I was having problems with it flashing after the notification was gone. Didn't notice any extra strain on battery though, although it could have been there.
At the moment it's 1 day 16 min on battery, with 20% Android OS and 5h 38m awake CPU time, is that high? (the Android OS bit/awake time)
Not noticing any drain with Lightflow... I notice that when an email/text comes in the phone wakes up briefly but whether that's Lightflow or normal I don't know... but the phone is asleep from then until I turn it on, even though the LED is flashing away merrily in the meantime. And I looked at this overnight - so getting an alert at maybe 2 or 3am and then actually checking it at 8am or so. Nothing abnormal between 2am and 8am, and noticed no extra battery drain.

Had this problem but I think I understand how it works now.
It will keep flashing if you have "individually" removed the notifications out of the notifications bar. Removing notifications this way doesn't seem to register in Light Flow but you can solve this by:
(a) running that app
(b) hit the "X" button to clear all notifications in the notifications bar.
Can anyone find a way to see if it really is Light Flow that consumes that much battery? I cannot really tell.
Hi.
Light flow will cause some battery drain, but I try to keep it as little as possible.
You will see a fair amount of time partially awake (not the screen on, but showing as awake in the battery usage) because of the app as every time you have more than one outstanding notification (of different colors) the app has to do a partial phone wake to run the alarm manager that changes the color.
There's a few things that can help this, firstly slowing down the frequency of cycling colors ("Notification - battery", in general settings).
Fast = 2.5 seconds
Medium = 5 seconds
Slow = 10 seconds
Very slow = 20 seconds
The other option is just to show the highest priority notification that's currently outstanding - then you'll just get 1 color (e.g. if you have an e-mail, missed call and sms message all outstanding - if you have priority of 1 set on missed call then only that will display of the 3)
Unless you really need them, all the additional light controls in the general settings menu e.g. button backlight, flash etc should be disabled to keep things minimal.
With the latest 2.7.x releases I found (on a nexus one) that the partial wake is for less than 100th of a second on every cycle change (previous version had got to about 400ths of a second)
As for not clearing the notification, at the moment I've got no hooks into swiping away individual notifications from the notification bar so they will keep flashing.
I'm thinking of adding an extra battery saving option where just the most recent notification type is shown as there wouldn't be the need for partial wakes for that.
The good news is I just got a Galaxy Nexus yesterday and after quite some time got the adb drivers working so I'll be looking into seeing what's possible with ICS soon.
So far I've just made one ICS specific change for the next release which is to remove the nag screen on upgrading about restarting accessibility as it seems google have finally sorted out the accessibility bug that caused the need for a restart!
Cheers for the clarification and help, andrewpmoore. Great app.
The option that makes the LED shows only the most recent notifications will be VERY WELCOME! Look forward to the update
Good Job, glad you finally have the handset! can't wait for the next release!
No issues here. I think it really depends on your settings those. Especially the color cycles.

Don't get too excited about the next release. It'll just be a bug fixes one (and the nag removal for ICS)
If there are any devs on here that can work out a way to pick up on the swipe to remove notifications could they get in touch. I've not found anything useful in the accessibility service so far.
Probably didn't see my question in another thread, but can you add a full RGB colour picker? Seeing as it's an RGB LED I assume this is possible, rather than just having the current, fixed, selection of named colours?
Great job andrewpmoore, will definitely use this as soon as my GN arrives
Don't need to worry about battery drain from Light Flow any more andrewpmoore.
I first tried disabling the app then uninstalling, I still had the same battery drain from Android OS, so my problem lies elsewhere.
I've reinstalled Light Flow now, great app!

It's something I've had on my todo list for a while. It'd be relativley simple for phones line the Nexus One and Galaxy Nexus, the difficult part is fitting it in with the "direct mode" settings and mapping colors between them.
I'll see what I can do.
Light Flow also caused Sleep of Death on my phone. I've uninstalled and all is well now.

Considering other people are getting the sleep of death without Lightflow it seems a little rash to decide that Lightflow is causing it.

Add to that the cases where people are using Lightflow and NEVER had the Sleep of Death, it's fair to say Lightflow is not the (sole) cause. It MAY be behaving badly with some other app I guess... but I've been running it since day 2 (18th) and never had the sleepy death thing.
I updated to JB last night, fully charged my phone, unplugged it and then went to sleep. When I woke up I only had 50% battery left, previously on ICS when the phone was idle over night it used between 2-5% max.
I then charged the phone again this morning and now 3hrs 10mins later, I'm already down to 66% and I have hardly used the phone. It's showing as:
Whatsapp 36% !?!
Android OS 17%
Android System 16%
Facebook 7%
HTC Sense 6%
Mediaserver 4%
Camera 3%
Is anyone else having any problems? With ICS I would charge my phone in the morning at work and it would easily last until the following morning, unless I was heavily using Facebook or playing a game. I thought JB was supposed to improve the battery life, not make it worse.
Give it a few charging cycles before complaining.
Have you rebooted the phone since the update.?
Some apps still are not quite complitable with jb,especially with new HTC sense libs or api.

Not me personally, but it did reboot by itself randomly. It's never done that on ICS. I think I'll do as you suggest, give it another day or so. If it still hasn't improved I'll try a factory reset.
What does the Power Saver option actually do? Does it switch off all data sync, lower the screen brightness etc?
Do a full wipe. Some apps could be screwed up while updating.

Most likely an app that isn't backing off nicely. When an app finds your data/Wi-Fi is off is probably getting in a panic that it can't call the mothership (or download some ads!) and is waking your phone or keeping it awake constantly while it tries and tries.
That app would cause the same issue if you turned off data and Wi-Fi manually.

So I installed android revolution 15.0 and the battery doesn't seem to be good at all... Don't know if its a JB thing or this particual Rom. When I check the usage number on power section, it says android os has a 2 hr wake up time... I also installed betterbattery stats and I am getting this wl1271_wake under the kernel section and this weird surfaceflinger under the processes section... Any insight would be helpful, thanks
Sent from my EndeavorU using xda app-developers app
I performed a factory reset last night - well the new equivalent in JB, which is go to backup and reset the phone.
After the reset, I setup my Google, Exchange, Hotmail and Facebook sync. The only app I installed was Whatsapp. Managed to get the phone to 72% charge before unplugging and going to sleep, I also made sure the initial syncs had all completed before unplugging the charger. This time it went from 72% to 30%, so 40% used while sleeping instead of 50%.
Looking at the stats, I think the battery counters are screwed up. When I first checked this morning, it showed Whatsapp had used just 2%. 10 mins later after a couple of messages, the battery had dropped to 28% and Whatsapp then showed as 32%.
Android OS never used to show much usage, the screen was always the thirstiest, but this morning it Android OS showed as ~30% which then dropped to 22% after using Whatsapp. Perhaps this is due to the screen time being integrated into the app counters as mickfitz said.
As you can see from the pic below, Whatsapp doesn't appear to be keeping the phone alive during the night as Phil suggested:
Surely others here use Whatsapp? Is no one else getting massive battery drain since the OTA JB update?
The only other things I can think of are the company policy settings which are applied to the phone when I setup my Exchange account, or Google Now - but for this I'm just using the default settings.
[EDIT] I'm not using Power Saver mode btw and I don't want to if it shuts off data while idle - it will mean I don't receive Whatsapp alerts
[EDIT 2] I've just had a proper look at the 2nd screenshot. The line chart doesn't match up with the battery % shown. It was definitely at 72% when I went to sleep yet the chart only shows 50%. I'll leave it charging all evening and check the line chart to make sure it's at 100% then give it another go tonight.
not sure if this app will help us to get a clearer picture of what is happening..
