Walk me through what you do to attain zero wakelocks please.

Juice defender, no juice defender, ATK, no ATK.
I get great battery, but betterbatterystats is still reporting wakelocks from google services and facebook.katana. Sync is on ONLY for facebook with 3 hour interval.
I used titanium backup to freeze:
-email
-gmail
-maps
-kies
-talk

You will never have zero wakelocks, as they are how the OS works.
If you have apps keeping a wakelock longer than they should, or when the screen is off you have a problem.
Also check the graph in settings > about phone > battery, if the awake and screen on lines line up apart from where you may have been downloading stuff, talking on the phone, listening to music, anything else where it would make sense for the phone to stay awake when the screen is off, then you are ok.

oh the phone sleeps perfectly, I just thought there was room for improvement what with 2 minor wakelocks. just a junkie for tweaking .
I un froze everything gonna scope out the batt life with no power saving apps/features.
[edit]Success! I got around to freezing some more .apk's with Titanium as per https://spreadsheets.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0Ag43oj7rLQP4dENZcmhGN0ZUa3pHSENVeXlqUm5vV0E&single=true&gid=0&output=html
and I'm getting 1mA power draw in idle/sleep according to BetterBatteryStats. Before I froze a few extra apps my best was 20 mA in idle.

you want zero wakelocks? buy a nokia 3410. As mentioned its excessive wakelocks you should worry about. Zero wakelocks means no point having these type of phones as you wont be using any of its features.

A logical step would be to actually use the phone for a week or two and monitor the wake locks in conjunction with what you are using on the phone .

The easiest way to do this - completely serious - is to just shut the phone off when you're not using it.
When you want to use the phone, you need to wait for it to boot up. That's one button and 30 seconds or so.
To freeze and unfreeze apps as you need them will take just as long, be MUCH more tedious, and still drain more battery while the phone is in sleep mode.

booting the phone drains a fair chunk of battery though (at least on my previous 2 phones)

You froze all of these?

I too have frozen most of what is in that spreadsheet but im unsure about talk as it gives a "caution" warning but i do not use this and i notice it is always in my wakelocks, can anyone who has froze this confirm that it's 100% ok to do so?

Finally fixed my battery drain!! Turned out to be Yahoo Mail!!

I have been reading a lot at this and other forums trying to find out why my phone would drain 5-7% per hour with screen off even though after installing various combinations of custom roms and kernels and following suggestions made by other users such as monitoring partial wakelocks in BBS, freezing applications, undervolting, turning off sync etc.
Having spent many frustrating days on this I finally managed to locate the root of the problem and wanted to share this with other i9100 users and hopefully this helps someone out there.
What I noticed was that after installing a customised rom (i used checkrom, hyperdroid, villainrom) the battery drain would be <1% per hour and the screen on time closely matches the awake time. However, once I had restored all my apps using titanium backup, the battery drain would go back to 5-7% per hour. I checked BBS but there was no particular app showing which was causing partial wakelocks (except the usual alarmmanager, etc) so I always thought it was a rom/kernel problem and not an app problem BUT i was wrong, it was an app that was causing my battery drain (in my case it was the yahoo mail app) and for some reason it was not showing up in BBS as causing wakelocks but u knew it was chewing up my battery as the awake time kept on increasing while the screen on time was not. Now I am using k9 install of yahoo mail and battery life is great!
I found this out by simply doing the following:
(a) Install a custom rom and kernel (I used checkrom HD v4 and siyah 2.6.6)
(b) Turn off sync, notify new apps, google ad
(b) Install cpu spy and BBS
(c) Open cpu spy and reset times and then quickly exit the application and then press the power button.
(d) About 10 minutes later, turn on the phone and quickly check cpu spy. It should say that the phone was in deep sleep at least 9x%. Also check BBS, the wake on and screen on time should be very similar.
(e) Then install titianium backup and start restoring 5 applications (I chose 5 but you can choose more or less)
(f) Go back into cpu spy, reset times and then press the power button
(g) Repeat steps (d) to (f) until you find that the deep sleep % falls below the 9x% and then delete each of the recently restored apps and repeat the process till you get back to 9x% deep sleep.
(h) Hopefully you would have found the rogue app then its time to find an alternative app!
Hopefully this helps!

Weird yahoo mail doesn't seem to drain that much of my battery, but I'm not really sure as I change roms so often I have no idea what normal drain for LA2 is(probably 2mA). I did noticed that it almost never used 2mA with data on.

A suggestion for you since you don't seem to be aware of it.
You didn't have to look at it for days and days looking only at partial wakelocks pull down tab.
All you had to do, was to go to bed on a full charge, then read the text file that you can dump from that app.
It contains partial, kernel, alarm wakelocks and processes.

2mA is bogue, in fact, all mA reading is bogus.. it's an estimated value by an app calculated every 5 mins or whatever you have set at, unnecessary wakelocks justs so you can get some fairy/harry potter numbers.
Only way this could be true is if you wire a multimeter to it.

It may be bogus, but it still shows drain somehow. What other could I ever place on my 3rd screen without the big battery usage history?

I agree that yahoo apps are bad. At least when I bought the phone with stock 2.3.3 and installing yahoo mess & yahoo mail my battery drained very fast and I didn't know the cause. The phone stayed awake most of the time even if the screen was off.
I had a hunch that maybe one of the 2 yahoo apps caused this and uninstalled everything yahoo related. Since then, my battery life was great.

Yep....and most of the time there are better alternative apps....just need to look for them. The battery still drains fast when i am using it but at least when i am not using it (which from my usage history is about 60% of the time on a normal day) its taking just taking 1% per hour and allows me to survive till i am back home to charge for the next day!

I never use yahoo mail in my sgs2 but my battery drain as normal, so i think no reason to talk yahoo mail is the reason.

He is right. I had problems with yahoo mail too.
One thing I noticed is that even though it has sync it does not show up in bbs. I mean it has sync so it must be using some battery over time, but it does not show up at all in partial wake locks. It show that the system is not reading the drain by yahoo mail. Such kind of battery usage shows up as android os.

Just use gmail instead =]

Yahoo messenger is really bad, it does cause a lot of drain, it runs about 13 processes, whilst skype hardly runs 2 or 3. Disabled start up for yahoo messenger using startup manager and running processes by AutoRun Manager. Unless necessary I don't use yahoo messenger, skype only
Never used yahoo mail in my phone.

Yahoo mail and Facebook apps were draining my battery,just stop auto sync and it's fine. )

Greenify?

If i can Root my 9005 - i intend to use Greenify,, as my battery is very poor (stock i'm lucky if i get 8-9 hours light/moderate use)
Is it a rated app,, can i expect big battery gains?
Thanks.

Depends which apps you have installed and how you use them. For example facebook drains much battery so you coukd greenify the app but if you do so you wont recive notifications anymore from it aslong you arent actively using the app.
In other words it prevents apps from wacking up.

As someone who already always manually force-closed all running apps, all I noticed was an increase in free time, as greenify is faster at it.
I didnt notice any increase in battery life.
If you don't manually force-close your apps, it'll probably have a bigger impact.

You will have some slight increases of battery of you force close the apps wich cause many wake locks like what's app

It seems to help mine. I run it with the Xposed Module that adds features that still preserve the notifications from Facebook, etc. I also have it set to boost mode for it to work faster.

I also haven't noticed much of an improvement. Many people swear it's a miracle app, for me it only turns off notifications.
True battery saver: green power payed version (on Google play). Set the phone to sync once at 4h and turn off wifi and mobile data on screen off. Awesome app, I tell you.

I do all that myself manually.... Sync always off and I turn Wifi or mobile data on when I need it, and turn it off when I'm done.
Cheaper than buying an app, too.
The real saver for me has been LUX. With our climate and the time I spend indoors, a brightness between -20% and 4% is more than sufficient. Now THAT saves battery! With brightness at 4, I loose 1% per 15 minutes whilst browsing! With it at 50, 1% per 5 minutes. At 100%, 1% per 90 seconds.
And when i use it in the dark, - 70%. I barely lose any charge at all whilst being an insomniac. It's been 20 minutes, still on 55% charge, which it also was 20 minutes ago. WiFi on, eWeatherHD update on, Tapatalk, Facebook and Firefox in use.
(if websites used less of that eyesore white, it'd save even more.)

I would suggest to remove some bloatware comes with the ROM / firmware itself.
It safes much battery though.
As well as turn on location, and on it when you want to use it.
And I freeze some apps which is running in background (which greenify can't detect it), which I don't use it as well.
and change to a good kernel.
it will really have a good deep sleep, never up if I never wake it up.
the apps running in background is only messenger apps like whatsapp, viber, and that kind of stuff. I never freeze this one and never put it on greenify as well.
So far so good.

I might look into that app. I go with the "free" lol DIY manual turn data/wifi off thing too, but sometimes I forget and I see wifi on when I had turned it off or so I thought. some apps are worth the couple dollars or so and I might very well get this one. Thanks for the tip on it. I like too that it automatically turns on wifi or data such as when you go to read an email or something.

You can also give these a try:
- Deep Sleep Battery Saver
- Juice Defender
- Tasker (You can configure it to auomate nearly anything, from 'turn on wifi at this and this gps location' to 'shut up completely between 2200 and 0800'. Does a lot of non-battery related things too, like launch a specific app when plugging in headset, or automatically move photo's from internal to SD.)

Juice defender is a dead project and 2 years old. Greenpower is basically the same app but still supported.

Hey thanks! I did go ahead with Green Power yesterday and I have to say I notice enough of a difference for sure. My usage has been with a phone call, check messages, several texts, check email a few times and some light surfing. i'm at 89% at 8 hours pulled off 100% charge and would have been lower for sure into 70s at best. definitely notice.

Lollipop battery drain

I got the German 5.0.1
IS it only me or is it general with the battery drain?
Even in Flight Mode, I am losing the battery in a couple of hours

Hello everyone, two days ago i downgrade to kitkat, I decide to re-put Lollipop because I'm documenting on various forums Italian and foreign, and this drain the battery does not have all .... well for my case I installed the GSAM Battery Monitor from Play Store that seems to work well with Lollipop. I left the phone idle and discovered that the deep sleep has never been reached. The phone was always active, even when locked.
GSAM has reported that the app "Unified Daemon (EUR)" was among the top three applications that consume battery.
According to various forums is a preloaded application from Samsung that unifies information like weather across other applications preloaded. I really do not know what good has this application.
I tried to turn it off, and in fact the phone goes into deep sleep with consequent consumption "standard" like KitKat.
The downside of disabling this app is that you lose the weather from the lock screen and through the window of the cover S-view, while the widget on the home seems to work perfectly.
Obviously there is to say that others should do the same test and see if this app will appear among the first applications to battery consumption.
A greeting

disable Facebook app (use web version) and turn off wifi when not being used. My battery usage has transformed! See other thread....70% after 10 hours. 56% after 13 hrs! Lollipop is buggy. Manage wifi manually and you're battery will be awesome.

^^^^this^^^^ . Me too. Disabled damn Facebook and it a few Google apps and I'm back to normal. The main culprit is the stupid Facebook. To make easy access of it from Web just make a shortcut on your desktop.

I will leave wifi on today regardless of whether or not it is connected and see if things get warm / battery usage ramps up. If it doesn't it might indicate an issue with FB alone or at least prove whether or not wifi is stopping the phone from going into deep sleep after a period of non use. Yesterday having left FB and wifi off, resulted in 40% battery remaining after 16 hrs usage. It never got hot once. This is my yard stick.
Lots of users are having issues with the latest update to facebook - just look at the comments on the play store!
Anyone else been having high battery usage but are not users of FB app on lollipop?

@gasland Here is what i did.
I uninstalled
Facebook, Facebook pages, Facebook messenger and com.facebok."something"....
I removed everything that had the name "facebook" and rebooted my device.
Battery has been okay since then.
Ps: I also froze "unified demon" as I don't use either of the weather services or finances or all that crap.

AOSPA Battery Drain

Hello, just yesterday i installed AOSPA on my P8 Lite ALE-21, and i realized the battery drains too fast. I had like 45% at the morning and when i was in school (not even 4 hours passed) my phone ran out of battery.. Someone advised me to disable 2 cores, but won't that slow my perfomance?
P.S: I installed Greenify, it won't help..

Walk us through a daily use of your phone: what do you leave turned on while in school (BT, GPS, WIFI, Mobile Data, etc)?
If you have your phone rooted, try installing BetterBatteryStats, if not, WakelockerLite and see if there any wakelocks active while your phone is in idle.
Also, make sure the "Wifi Scanning" and "Bluetooth Scanning" are OFF in Settings->Search-> type "Wifi" -> Scroll down to Wi_FI Scanning"
Changing that and Settings->Wifi-> Gear icon -> "Keep Wi_Fi on during sleep" to "only when it's plugged in" helped me, alonside Greenify.
We will have to wait until all these problems are fixed

If I have my phone in idle, even with the Wifi turned on, i don't have that much battery drop.
Something is preventing your phone of going into deepsleep. Which apps do you Greenify? Do you have "Automated Hibernation" turned on?

Well, social media apps tend to drain battery running in the background so I always Greenify them.
From time to time I open the app instead of waiting on a notification but it's a choice I made.
Try turning off things like Ambient Display, head to Settings > Display and select to turn off Ambient Display (which means no app notifications will cause the screen to wake).
Also, if you're using apps that require your location, you can head to Settings > Location > Mode and select “Battery saving” (where Wi-Fi and mobile networks are used to determine your location) over “High accuracy” (where GPS is also used).
You should wait of further updates to the ROM, since there are issues regarding the battery drain.
