Perhaps my tone was a bit strong but the answer to your question is 'yes', it does use battery. It may not be up there with 3D gaming in terms of battery use but consider this...

You have a process and one, maybe two services running all the time your phone is on. How can that 'save' power as the dev claims?

The answer is it doesn't, it USES power. If you look through the Market comments, a good number of users have said the same.

I am never going to tell anyone to uninstall anything, after all it is their device. But if people want to save battery, I will point out where they have options.

The thing that makes me laugh about Screebl's description is "Never have the screen turn off again while using your phone, and SAVE BATTERY too. It's possible with Screebl!"

Ummm, excuse me but that is just a load of *&%$"£$@ if we actually think about it.

LOL ;)
[BetterBatteryStats] manuelkuhs:
I agree with your general philosophy re. both battery usage and people's freedom to use what they want:)

I guess with Screebl, the idea behind saving battery is that you set the screen timeout for your phone extremely low, and then Screebl will prevent the screen turning off while you hold the phone, and once you put the phone down the screen will turn off immediately.

I guess whether it saves battery depends on the balance between power consumed by Screebl and power saved by extremely low screen timeout...

Once my phone drains battery at a normal rate I'll see what Screebl's impact on battery drain is; I will probably use it because I hate reading a long e-mail and have the screen go dark. Not a big deal, but what are smartphones for, eh? ;)
[BetterBatteryStats] nobnut:
I agree fully.

The only thing I would add is that the process runs all the time.

The battery usage will not be high I agree, but every little helps.

[BetterBatteryStats] Irontiger:
But as I understand Android a running background process doesn't use any energy as long as the phone is asleep. And Screebl doesn't wake it up, but stopping it from going asleep.

Am I wrong?

Thanks for the infos above ;)

Looking at the "other usage" you phone did not sleep at all during the test. So you don't have a wakelock problem but maybe a problem that your kernel does not go to deep sleep. If it's stock it's improbable but worth looking at the kernel logs for suspect PM or Power* entries. If it's an alternative kernel you can maybe find confirmation in the thread to that kernel or talking to the dev.
[BetterBatteryStats] nobnut:
I don't see it like that but in principle, yes.

The way I see it is like this... what powers the RAM? Yes, the battery. The less in RAM, the less power used.

I wish it was gravity holding RAM processes but it isn't.

Please use it if you want to. It's your device.

I believe tasker uses the android location service and does not release any listener when phone is off (in fact today's tests on a new app showed exactly that)
[BetterBatteryStats] DrunkFuX666:
Sorry guys but I can't seem to find any advice on how to deal with this alarm manager issue... nobnut said look a few pages back but I found lots of good stuff like gemini but not about the alarm... can you plz mention it again...??

And by the way I turned off the handcent LED notification yet its still causing the wakelocks... any suggestions...?? The main reason why I started using handcent ever since I started using android was due to being able to turn off that obnoxious autoconvert to MMS if Sms exceeds 3 messages... then the other customizations I grew to like even more... wouldn't want to uninstall handcent unless it was totally necessary :s
[BetterBatteryStats] nobnut:
I don't think there is any definitive fix for the alarm manager. Chamonix mentioned it previously and having fewer alarms and reminders does help. I am on my handheld until tomorrow but will search and post more for you then.

I was waiting for my ID to be registered by the dev's end when random touch screen hotspot was going on. It was like apps were getting enabled remotely. One app after another was getting highlighted in the home screen.

I uninstalled this and everything is back to normal.

Not sure what happened.
[BetterBatteryStats] manuelkuhs:
Thanks, I will have a look at that soon.
[BetterBatteryStats] manuelkuhs:
So things are pretty strange here. I've installed Current Widget (log attached) and have had screen off & 3G off for most of it. Just before plugging in for a charge I even turned off 1/2G for a while (Airplane mode). The Android system showed that it was asleep whenever the screen was off (most of the time).

It was still showing a current of at least 150mA.

Even more strange, though, in the last hour before charging, at which it showed current of ~150mA, the battery only reduced by 1% - which suggests a real current of 15mA! Similar pattern visible for the 2 hours before that.

And as you can see, once I plugged it in to charge (just USB), the battery % increased very quickly, suggesting that the real drain really was that small.

Strange or what?

Remember that before my battery did actually drain several % within an hour of being idle.

I will do a final trial for the next 24 hours with more heavy usage. Most likely I will get a replacement on Saturday.
[BetterBatteryStats] Irontiger:
Ok, if you see it this way your right. I didn't know that 1 or 2 MB in RAM could cause such a significant power loss. Thanks!

[BetterBatteryStats] nobnut:
Hmmm. Reset, two unrelated tests, similar results... if it were my phone it'd be returned.

It's a shame Android devices can be so mysterious.

It's your call.

I'm going to attribute the midnight battery usage as a fluke one off thing. I haven't been able to reproduce that event, whatever it was. I'm pretty happy with how my phone is running atm, I've cut down on the background processes so much that when my SGS2 goes into a deep sleep, it doesn't draw any current! LOL (impossible I know, but it's a cool thing to brag about)

I still have a high wakelock count with Alarmmanager though, I'm not entirely worried about it though.

Definitely going to buy this app once it hits the market. :) Thanks Nobnut and Chamonix for their help!
[BetterBatteryStats] Sincitybronze:
Hi guys,

When I turn my data off, I sometimes get email wakelocks. I do have an exchange account. I tried using "push" and then attempted polling the server every 30 minutes, but the wakelocks continue. Is there something about exchange, specifically, that contributes to this problem? Do you recommend using IMAP or pop instead? I'm curious about why I get wakelocks even when I set up the stock email to check the server every 30 minutes. I am using a Froyo ROM by the way. I know, it's old, but I'm on a Samsung Vibrant, so the stable ROM options are limited. Thanks!
[BetterBatteryStats] gaui:
I had constant wakelocks when I used Exchange. Changed to IMAP 30m sync, everything better! :)
[BetterBatteryStats] jeremysherriff:
Guys, just an FYI - disabling components of the Google Services Framework is not a recommendation, should not be necessary, and you should be aware that you are simply hiding the symptom, not the cause.

The cause is poor data connections, caused by either poor cell reception (therefore poor mobile data), or poor wifi connection or setups.

In these situations, your should:

Drop back to 2g (or 3g if on 4g) when the phone will be idle, or background data only, except when using the data connection for interactive activities (i.e. web browsing, streaming) - put a shortcut on your launcher to get quick access to the settings, use your power notification toggles, or get one of the widgets free from the market to make this easier.

Change the wifi sleep policy, either to keep wifi alive (if you have poor mobile data) or to put wifi to sleep (if you have wifi connection issues) so that the background/idle activity uses the connection that has the best results.

Try different radios or kernels or modems or basebands, or even ROM's.

Reconfigure your wifi access point to use a different channel - get "Wifi Analyzer" free from the market to check what channels are best/free in your location.

Try using a static IP address on your wifi connection instead of DHCP. This has had success for some, and not for others.

Change wireless provider if you have the option - don't be fraid to move provider if they provide poor reception in your areas!

Make sure you don't under-clock your phone too far - the min CPU frequency generally won't save your battery life, and if it's too low then the phone won't wake easily to carry out the alarm and wakelock processes in an efficient manner. For the same reason, don't be too agressive in your choice of CPU Governor. Generally, whatever the stock setting is for your kernel, is going to provide the best and most consistent results. CPU freqs/governers affect more than just gaming stability and FC's - they affect everything your phone does!

HTH..
[BetterBatteryStats] riskaa:
Hi all,

I've had the best battery life i have had thus far, even though it's not much. I'm getting about 13h on my battery - and i'm very thankful for that, and for the recommendations i've had from this thread.

So far, I've uninstalled Any.do, changed my K9 to poll every 15 mins instead of push, and disabled facebook notifcations completely.

When my phone is idle, the battery level remains pretty stable - this is way different to my story last week, when my battery was draining a lot, even in idle.

Now, i'd like to get your input on how to keep the battery lasting longer, when i actually use the phone. it seems to me, it's draining pretty quickly when i actually use the phone.

Here are a couple of screenshots and a dump file.

Not sure why Facebook is still waking the phone up, when i have it set to "never"

Any other ideas would be helpful too.

Thanks!
[BetterBatteryStats] jeremysherriff:
Your number one problem is MyPhoneExplorer:

Wakelocks
=========
MyPhoneExplorer Client (com.fjsoft.myphoneexplorer.client.MyPhoneExplorer Client): 1 h 44 m 9 s (6249 s) Count:8 17.7%

We need to see the alarms information, it should have been included (because you have root) but was not. Check your next dump file, if it is still missing then uninstall/reinstall BBS and make sure to grant it root access where needed. This is a problem I have encountered when upgrading, a remove/reinstall fixes it.
[BetterBatteryStats] gaui:
Hello,

I have Any.DO, why is that so bad?
[BetterBatteryStats] gaui:
Hard to see without root. But I advice...

- Uninstall Facebook app (install FriendCaster instead)

- Don't use Exchange, use IMAP instead

- In Settings -> Wi-Fi -> Advanced -> Make sure "Keep Wi-Fi on during sleep" is set on "Never"

- In Settings -> "Location services" make sure to uncheck everything
[BetterBatteryStats] jeremysherriff:
Please attach log files, or provide a link to a dropbox or something. posting the technical data here just clutters up the thread.

I see nothing obvious. Are you willing to get root access, so we can see your alarm information?
[BetterBatteryStats] gaui:
I froze a few apps, installed stock kernel (NetChip) and KI3 modem and this is the first experience...

Hope this holds!
[BetterBatteryStats] Karpfenhai:
Does this indicate you're loosing 1 % per 7 mins with screen and wifi on?

My Series shows me 1 per cent in 1 hour 25, sync and 3g on but standby, testing speedmod right now ;)
[BetterBatteryStats] gaui:
Yup!
[BetterBatteryStats] Karpfenhai:
kk, heading for my bed right now, looking forward to your results tonight.;)
[BetterBatteryStats] chamonix:
Regarding NFC: I have the same behaviour but not as drammatic as you mentioned it. I remember Frederico Franco saying something about reducing those in one of his kernel's release notes. You may try that one,

mipi-link seems indeed to be associated with the camera interface. There has been a known bug and a workaround (related to gtalk) where some connection to the cam was held from boot time. Workaround was to open and close the camera after boot to release that.

In how far those are still required is unclear to me.

I have mipi-link bothering me sometimes (wakelock time higher that PowerManagement) bus most of the time it is minimal, same for NFC.

Note I am on a 4.03 ROM (RGB) and Frederico Franco Kernel Milestone #2

I've had AudioOut_3 (1013) partial wakelocks draining my phoens battery. What is this and how do I stop it?

First dump file after cleanup

Hello,

Yesterday I read ~ first 150 pages of the post and took some measures to try to fix my battery draining problem. Deleted a bunch of apps (including JD which I noticed doesn't make some peoples phones too happy), changed email push settings to interval refresh, don't run any backups other than from titanium, and run 4g. Also picked up Android Weather as recommended in an earlier post. This is the first battery stats dump I have pulled and would like some input on if there is much more I can do at this juncture. I think I have at least fixed the majority of the problems I saw from other peoples posts.

Running CM 9 nightly (most updated version...last nights I think) on LG Nitro HD from AT&T. I only use wireless at home (see 4g in Norman, OK above). Wifi is turned to shut off while asleep and not plugged in.

I really only use sportscenter app, email, and default text messaging app. No social media apps installed. This is from sitting at my work desk for little under 3 hours (good 4g signal here). I live in Norman, OK (which is somewhat in a lower valley area compared to where I work in OKC) so I am going to provide another dump from an overnight session. I am guessing that I won't be able to get much better with this clean, app free build on my phone with a 2.75 hours and awake 6 m 19 s, but would like some input if there is any for this first dump file:
[BetterBatteryStats] Delhi-Boy's:
Thx for this it's really cool. now i can take look at, what is eating my battery like hell:D

What is the deal with gprs-data-stall? Is that my email app?

I will switch over to IMAP. Appreciate the help
[BetterBatteryStats] riskaa:
I don't know about your phone, but it seemed my Any.Do was waking up my phone all the time. I couldn't figure out why. So i uninstalled it, since I don't use it that often anyway.

Does yours not cause any wakelocks?
[BetterBatteryStats] chamonix:
Don't worry about that wakelock, it's probably because either you have been listening to something, or there has been a sound lotification or you have sound feedback.

Your awake is mostly based on sync. You have quite a large amount of services syncing (docs, browser, mail, contacts, plus) and (maybe because of bad coverage) this sums up with quite some overhead (syncloop wakelock).

Please post a complete dump after revisiting your account setings and make sure alarms and kernel wakelocks are included
[BetterBatteryStats] chamonix:
Your effort seems to pay out: 6 minutes out of 2 hours is pretty good. The main reason for the awake are sync and alarms (partly showing bad coverage situations). The second may be the reason for the first but I also read that gmail had some problems for some users today so it may also be part of the cause. For that reason I recommend that you take another reading for a little longer so see if part of the awake was due to a one time situation
[BetterBatteryStats] chamonix:
gprs data stall is a condition where the data connection stalls due to bad reception or cell handovers. This results in doubel overhead as frequent alarms will be waking up the phone and the overhead of reconnections and repeated connection attempts
[BetterBatteryStats] JoeSyr:
I actually came here to ask about this very thing. I just set my Galaxy Nexus to 4g +wifi and left it over night to test the battery effect. The BBS log this morning shows 365 wakeups for com.android.internal.telephony.gprs-data-stall, but only 3 for com.android.internal.telephony.cdma-reconnect.

How should I read this? The different ways I can think to interpret it are:

-The gprs-data-stall just a normal process when the phone is sleeping on wifi, and the low reconnect confirms this.

-The gprs-data-stall is excessive, and the reconnect is a separate process (data is stalling, cellular connection is fine).

In the hours I've been using the phone so far today, the totals have bumped to 559/6, on a mixture of 4g on and off. I'm not seeing bad battery life for it, and I haven't thought of where I am as being a bad service area, but does this look abnormal?

Edit: To clarify, the way I've seen wifi's interaction with data connection explained, my phone shouldn't be trying to maintain a data connection while wifi is on, and that's mostly what I'm asking about here.
[BetterBatteryStats] gaui:
+1

I think this is a bug in Android ICS base, because I've been seeing this in many ROMs (Sammy based and AOSP/AOKP).

I'm going to post a full run too, but right now its worthless, cuz im on wifi tethering which literally eats my battery..

Thx for sharing and your patience following my advice ;)
[BetterBatteryStats] JoeSyr:
Another question, this one more about BBS itself: I have an app (1weather) that I can see is using the battery under the normal ICS battery stats. When I made the attached BBS log this morning, 1weather showed up in normal battery stats as 10%, so I know it was active during that time. But there's no trace of it in my log.

Not trying to minimize this app's activity or anything, but I'm just wondering why it doesn't show in BBS.
[BetterBatteryStats] gaui:
So here it is... http://imgur.com/a/3KUxH (all the screens)

I would have gotten 24h+ if I hadn't snoozed the alarm like 20x this morning haha. :D
[BetterBatteryStats] jeremysherriff:
Is it possible that all CPU was foreground activity? If so, you would only see it if you enabled "processes" in the dump file settings.

I realise it must sync at some point, but perhaps you didn't capture a sync event in the 10h of log. Maybe it sync's every 12 or 24 hours..
[BetterBatteryStats] legato89:
about an hour is lost because my phone locked up and crashed while on the Google music desktop page.
[BetterBatteryStats] JoeSyr:
Actually, while looking into this I noticed that the program had been set to sync every 30 minutes, I must have re-installed it clean at some point and not re-done the settings.

Just over 24 hours later now since that period began and the app only shows 11s of foreground activity vs 14 minutes of CPU time. (normal battery stats).

Current BBS log attached (changed settings to include all), and the only place it shows up is in processes, where it seems underreported vs the normal battery stats info. The app appears as "com.handmark.expressweather".

Hi,

I was wondering if sum1 could look at my log and guide me on what should I do..here is a complete log + all the picture i could take :/.. i know a bit excessive but i didnt know what exactly would u require !

I have attached two graphs + DUMP file. I have attached all the screen shots for all the pages so if that would make it easier for sum1.

Would really appreciate any help that i can get :D

I forgot to mention, that Samba File Sharing/Bluetooth were used to transfer the files b/w computer and phone so if it shows up in the logs it can be discarded.

Secondly please ignore the first image in detailed screen shot..using 2.3.6 the second one is valid.
[BetterBatteryStats] itsLYNDZ:
Is there a way I can tell what its sucking my battery life while I'm using it during the day? I was downtown for a few hours yesterday and used maps and GPS for maybe 15 mins and by the time I went back home 4 hours later my battery was at 40%. Unplugged in the morning at 100. I even have the extended battery so whatever it is that's eating my battery must be pretty bad to drop that much on an extended battery
[BetterBatteryStats] jeremysherriff:
You should have taken a BBS log file once you realized, and then rebooted to clear the lock. It'll be most likely the GPS sensor not unloading the driver but without a log file we're only guessing. Try again this weekend to do a similar activity with your device and see if it repeats. Also, get commandcenter from the market and use it to take a logcat file.

Guys, I would be really grateful if any of you could take a look at my BBS dump (http://pastebin.ca/2137973). As I've figured out in another topic, it's not a problem of modem firmware, what at first I thought could be the case. I wonder how could I get rid of 'No or Unknown Signal' and 'No Data Connection'? That's actually the only thing I am suspicious of now, as there's not much left. Oh, and the place I live in offers moderate phone signal so I guess that's not the case?

Have default account syncs

Facebook installed and widget

Sounds on (unlock, keyboard, etc)

Auto screen brightness

Other potential issues:

Not always great reception at work, so wifi is an option
