EDIT 23 FEB 2012 :
=== THIS THREAD IS OBSOLETE.. THERE IS A LOT OF DEVELOPMENT FROM ATRIX-DEV-TEAM AND FAUX SINCE I LAST POST, AND WHOEVER FOUND THE SAME PROBLEM BETTER TRY THE NEWER KERNEL.. ===
Old Post :
This is CM7 stock kernel extracted from CM7weekly29jan. Credit goes to Atrix-dev-team.
I found out that this is the only kernel in Gingerbread for atrix doesn't have Partial Wakelock by AlarmManager. I know that stock froyo doesn't have wakelock too.
Half day using this kernel, AlarmManager only wake for less than 30sec, and take less than 1% of the whole partial lock, compared to before, it could take up to few hours and 90%+.
I create this thread so that CM based ROM (CM7,Miui,Neutrino) user can test this kernel, if this non-wakelock really improve battery or not, or its just show different kind of log and had no effect on battery.
I only got hold atrix for a few day, a friend ask me to unlock the bootloader, and I have returned it.
If this really improve battery, I hope this can brought attention to developer on how to fix partial wakelock by Alarmmanager on stock kernel. If this thread is no good, feel free to delete it.
This CWM replace boot.img and /system/lib/modules/dhd.ko from CM7weekly.
I used CWM script from faux's, and replace those 2 files.
It is recommended to backup your rom before installing this.
Edit 05feb2012:
I'm sorry, I shouldn't have started a thread of a device I don't hold anymore. Today faux have released his new kernel, it might already solve the problem as and I couldn't test it. But for clearer view on why I started this thread, what I mean is that I saw BetterBatteryStats shows this. This is screenshot from other device as example.
On my defy, the percentage never goes above 1%. But on atrix, it could go above 20%, I even seen it on 90%+. Using CM7weekly29jan kernel, it always stay below 1%. And about the time AlarmManager is on, maybe I was wrong, it was not below 30s, maybe 1minute+, but before, it could go hours. Problem is I only tested for around 6hour. I just install the kernel, no wipe or clear cache. On that short test, I left the phone idle with screen off. I check on Battery Monitor Widget, it seems that each 1% of the battery can last slightly longer than before.
I hope this can make things clear.
Note: For quick test, you should see the partial wakelock 'since unplugged', not 'since charged', because reboot will reset the timer in 'since unplugged', but the 'since charged' will not reset unless you plugged the usb port for charging.
More info : device is Atrix International, last fullsbf is 2.3.4.45.0.20SEA.

Could somebody point me a commit that fixed this issue? What was the reason of this issue? Could this fix be applied to the stock kernel too?
Very interesting! Will test this weekend, sounds promising if it really does improve battery life on cm7 based roms, maybe talk to clemsyn or faux about it.

On other kernel, switch off screen for 10minutes. alarmmanager should wake for more than 1minutes. with this kernel, always below 30sec.
But whats important is the effect on battery life. A proper test would be night time battery usage, wether its the same as before, or gives better battery life.
I search for the commit too, but couldn't find it, I got no knowledge on building android from source.
Interesting.. anyone trying?

I'm sorry, this indeed just a rip off from weekly29jan, if this is not appropriate, I will take the zip down.
I make the zip so its easier for people who want to test. From my short test, BetterBatteryStats show smaller wakelock by AlarmManager, but I haven't test it long enough to make sure how the effect on battery. If this indeed have impact on battery, I hope enough to get dev's attention to fix the wakelock on stock kernel.
bobo9900 gave proper credit to the dev-team and is just posting the file for easy access with his thoughts on possible improvements of battery life. There is no need to give him a hard time for that.

The word "ripoff" was probably what rankled a bit, as the word normally implies theft. Possibly a better phrase would have been "was this from the 29-Jan weekly?" or something like that. Less loaded phrasing that way.
After initial testing, I'm not seeing a reduction in alarm wake locks. Will give it a full cycle to test battery life

Any updates on this?
I'm running MeanROM 3.1 with Anthrax RLS 06 and am seeing substantial wake time from AlarmManager.
I've used Gscript to dump the AlarmManager log, but I'm not entirely sure which parts to scrutinize. I also don't know how to wipe this log and start fresh... I recently flashed this rom/kernel combo after running Chad's modified superwipe, yet this log seems to span 50+ days.
My relative complained that he suffers from a steady battery drain somewhere around ~2% per hour even when he turned off the screen. If anyone is wondering, no it hasn't been flashed nor rooted before. Didn't get the chance to Help??

Its really hard to tell exact solution without knowing cause. First try to identify cause, use betterbatterystats app to know which wakelocks are causing this, you will surely find problem using BBS and eventually solution !
A very common scenario is running app in a background which is either using location sharing using GPS or data sharing using internet connection..... might be syncing opetation as well........
There are lots of threads on battery use & battery drain. Look at a few and see what may be similar to your issue.
We almost need a separate forum for "Help: Battery is draining!" threads, no? The trouble is, they mostly have the same answers, so many of us get bored answering them.....
Okay will try. Thanks.

OK, I know the battery life issue for 4.2 ROMs has been beat to death, but I've got something weird happening with AOIP on my phone that doesn't happen with other ROMs.
Basically, when I'm at work, the battery graph (from Battery Monitor Widget Pro) looks like in the AOIPbattery image attached below.
As you can see, it ate all but 3% of the battery in about 11 hours. At times Battery Monitor Widget Pro indicated it was using the battery at 11%/hr or more! This is while I'm at work, and the phone is not doing anything, just sitting on the desk with the screen off, connected to a wifi network but not doing anything with that either.
After a few days of that, I decided I needed to try something else. Originally was going to go back to my "old reliable" backup of 4.1 Rootbox, then thought instead that I'd try the last build of 4.2 Slimbean I still had as a backup. Restored that and got all my current data for the apps reloaded, seemed to be working fine (though still had the stuttering and dumping of apps issues, which was why I wuit using it). Thing is, it's using battery not much faster than the Rootbox one did. See the SlimbeanBattery image to see how it did at work. Same scenario (sitting on the desk, connected to wifi, screen off almost all day). The little bit of high usage was while I was at lunch, reading some web pages and rss feeds, so the screen was on for about a half hour.
So, I'm wondering what the heck is making it use batter so fast on AOIP? I tried several things before switching to Slimbean. Airplane mode made no difference. Used Wakelock Detector to see what was using it up, and it was some part of Android OS making AlarmManager go nuts with wakelocks.
I even backed everything up, factory wiped it a couple times, then loaded the base AOIP 6/3 ROM and loaded GAPPS to see if it still did it.
Nothing seemed to make any difference.
In one sense, I'm hoping the new build that keeps getting hinted at might correct some of this, but I kinda doubt it considering how everyone who brings up battery issues usually gets treated.
That's normal for 4.2 Roms

I see your point, why does one 4.2 room use that much more battery life then the other, it makes no sense to me. Maybe camcory can shed some light in this issue

That's how my battery life has been on all 4.2 Roms. If aoip is worse for you then most obviously you need to switch Roms.
Sent from my HTC One X using xda premium
I really was hoping that you would see that there might be something wrong with AOIP and take a look at it at least, and not throw out the same tired response. While I do appreciate the work put into AOIP, forum thanks have not happened due to the refusal to notice the glaring issue that everyone else does.
I would really like to know if you even read my post, Smartguy? Seems not or you would have noticed that AOIP in that scenario eats battery three times faster than another 4.2 ROM. Why?
I'm not trying to upset anyone, just trying to hopefully get this resolved in an amicable manner.
Some people don't have battery drain issues that bad with AOIP. You should keep in mind that this phone was never intended to run anything above gingerbread. Every one of these phones handles issues differently, which is unfortunate, but if a Dev doesn't have the same issue it is hard to address. Its just how it is.

Yes I read your post I wouldn't respond if I didn't. I have ran all the 4.2 Roms and with all of them I might get 10-11 hours of life. So no I don't see a problem with the ROM and if you do use another one.

Wow hard to believe (well not really) this horse has been beat to death more times than a cat has lives! I'm pretty happy with battery life for the performance and OS I'm getting with AOIP. No hiccups and I have access to all the latest android features. The phone has a small battery anyway so if you want better battery life, time for a new phone or switch to a Gingerbread OS. I charge the phone once a day typically so that's hardly an inconvenience.
Thing is there is something major different in AOIP, as I can typically get just over 24 hours out of this battery in anything other than AOIP, including while I'm at work where the battery usage is a little higher than at home in every ROM I've tried (4.1 and 4.2 based included).
AOIP for some reason eats battery at more than 10% per hour only when I'm at work (less than 3% per hour at home) even when I haven't loaded any apps.
Every time I look at what is using it, it is either "cell standby" or "android os" that is using the most with the other of those two second and the screen usage following in a distant third.
I've tried to figure out what specific item in those two are the source, but it always comes back to some generic service or component in the os that is used by almost everything.
Really any advice to try and improve this, other than "use another ROM", would be appreciated.
Try putting your phone in airplane mode while at work and turn on WiFi. That might help with eating the battery. Especially if where you work had a poor cell reception
Sent from my SGH-T679 using xda app-developers app
get a new battery. i dont know what else to tell you. if you are getting 24 hours out of every other 4.2 rom youll be the only one. as i stated i get 10-11 tops on ANY 4.2 rom. so you have 2 choices new battery or different rom
Best thing to to is kill background data turn off Bluetooth WiFi sync and locations when not using your phone for a couple of hours. But your best bet would spring for an 2900mh battery.

go back to gingerbread OS. we gave you suggestions already. 1) new battery. 2) gingerbread OS. simple as that
I just don't understand this. Why is it that everyone refuses to see that there might be something wrong with AOIP compared to other _4.2_ ROMs?
I wasn't complaining about battery life on 4.2 ROMs, just noting that ONLY AOIP has this issue that I saw.
All other 4.2 ROMs used less than half the percent per hour as AOIP.
Telling me to just buy a larger battery when I don't have the money for it is not an acceptable answer. Neither is telling me to go back to the crapload called "gingerbread", whose only advantage is battery life, at the drawback of making everything else run like crap.
Guess I shouldn't have bothered, since it seems the developers may be able to code, but sure could learn a thing or two about listening to others with valid issues they should be addressing in their code.

It didn't matter what I installed or didn't install. Once I got the phone at work with AOIP on it, it ate the battery three times faster than any other 4.2 ROM. One time, to rule out anything I was setting or loading, I loaded AOIP, gapps, then put in my account info and disabled auto updates with nothing else changed. It still did it.
As QA software tester, I know how to identify software issues and bugs. The only explanation for what I have happening is there is something going on with AOIP itself to cause this. Like I've already demonstrated other 4.2 ROMs only use the battery a little faster than RootBox 4.1 (RB about 0.6%/hr vs slimbean 4.2 using 1.1 to 1.5 %/hr) with that screenshot in my OP. AOIP uses about 2.5 %/hr at home but over 10%/hr at work.
In any case, it's quite apparent now that this little group of ostriches with their heads still stuck in the sand isn't interested in hearing the truth, so consider this a closed thread.

Hi, I have had my HTC One for a good while now, and I have been hopping between roms to try and find my favourite. I have just switched from GPe to InsertCoin. I have been getting what I think is very bad battery life on every rom I've tried (stock, GPe and InsertCoin) that I can't explain. Is this a software issue or is there something else happening here?

Indeed it seems a terrible battery life, but I bet you didn't let the ROM settle. If you continously change ROMs you'll get bad battery life, you should keep the ROM for at least 3-4 battery cycles to get an idea of battery life. Another suggestion I could give you is charge it while turned off, sometimes the phone shows it's full, but actually it isn't. Leave it till the light turns green, turn it on and than another half an hour

Yes I understand what you mean about letting it settle, and I probably should have mentioned that I have had bad battery life while staying on GPe for several months. I saw the same thing I don't understand: Android System using about 80-90% of battery in the battery usage even though I was using the phone and there seemed to be no long wakelocks...

Sent from my HTC One using Tapatalk
Every once in awhile I notice unusually big battery drain. it is almost always one app or another, not very easy to spot, it takes some amount of trial and error. my flow is:
have BBS at the ready, ideally your phone rooted and ensure BBS has root permissions. measure battery consumption at night, during the day for at least several hours. check the culprit app in all tabs, sometimes BBS doesn't seem to get access to all wakes for instance I could only find the trace of the drain source under network usage. usual battery drainers are google location based apps but I've also seen a system file Explorer that would gain access to network too frequently while in background. hibernate or freeze/disable those apps as you see fit, rinse and repeat. regardless of the rom I get in the end approximately 0.3%/hr of batt drain at night, 0.7%/hr during day while phone is in standby. I keep in background llama, accuweather, Tapatalk, mail, Dropbox, textra and a couple system apps. I use greenify to hibernate user and system apps alike. I only turn on location when I do need maps.
hope that helps.

That is a very common issue with Kitkat on the ATT Note 3. Custom roms have helped it, but not much. I use to get about 2 days out of my phone. I switch batteries everyday now. I have the spare battery charging system.
So we can only wait for ether the bootloader to be unlocked or for ATT to fix it.
Unrooted and can only get 18-23 hours of charge after the Kit Kat update. Before I could do 2-3 days, easily!

A word to the wise, I wouldn't be mentioning KR around here. It is considered a taboo subject after what the creator did.
android core apps always used to show as the top battery culprit for me under 4.4.2 - the google search app with the cards ended up being the app i isolated for my issue and disabling it fixed my battery drain issue.
I have also read about a bug with the camera app - but I haven't consistently had that issue so I stopped restarting my phone after using the camera.
My battery life has also went down since the kitkat update. I am at 36% at 11hrs 39min and 3.5 hrs of screen time. That's not bad, but previously I would be around 50% around this time...
