I solved my battery drain problem

I was having a problem with fast battery drain on my SGS2. I would get 15 hours if lucky from a full charge with light - moderate use. My most recent charge looks like it has doubled the time.
What did I change? I did a factory reset and manually installed all my apps, NOT using titanium backup. I had used titanium backup to restore apps only, that were from my previous phone (Nexus1). I have never used titanium backup for system settings, only apps, but it seems even that is unreliable. I've now stopped using titanium backup completely.

Can anyone verify this...
Will it matter if it's i9100 to i9100, or just any other phone to i9100?

Well... Ive done several hard resets , because I though I had a network problem , and I many of those I didnt install titanium or even root the device and the battery life was the same.
Just one opinion..

If you notice a higher battery drainage than normal then you have to see what application you've installed lately. If you can't find it then the only option is to do a Hard Reset. That has worked for me, IF your battery is drained by some app which you've installed lately.
Regards.

I am sure battery drain has to do with the apps we installed and the settings we use.
We are in a fortunate situation that my wife and I have both S II, hers is 2 days older from the same shop, so I assume both devices are from the same batch. Hence no hardware difference.
I installed a lot app and played with lots of settings and if my wife like it, she "demand" to install it on hers too, so hers is a more controlled env.
For some reason my battery drains a lot quicker than hers. I still have to find out which application / settings cause this.
For an experiment, we did not use both phones for a full day (very difficult), so all the drain is due to background processes.
There are several dips in the graph, but those are explicitly usage of the phone for a while. The big last drop on her battery was because she was playing a game for more than 3 hrs.
PS.
A collegue of mine (also an SII) had his battery run out quickly, until he found out his culprit: Settings->Location and security->Use wireless network was ON.
You can see the effect of this as the "almost horizontal bar" in my wife's battery when we turned it off.

thx for info man.

What would happen if i turn that off? I want to try this to preserve my batt life. Thanks!

PB_2003. You had to use one phone to make a shot of another phone? Just hold down the home key and press the power key. You will be able to take shots like the attached.

I have used TV to restore many times and battery life is fine. I'm would suggest that the issue is some app you are restoring rather than TB

I wonder if having 3rd party launchers like launcher pro drains the battery quicker. I installed launcher pro without ever having really tested the battery life of the phone with the standard launcher. Has anyone here tested the difference, if any, of the battery life of standard v market app launchers?

The screen shot on the left is your phone correct? It looks like something is waking your phone up and leaving it in an awake state for far too long. Your graph represents over a day's time and I see those huge chunks of time where your screen is off but your phone is awake; I'd say some program is what do they call it *wakelock* every now and then.

By the looks of it, the screen was on the entire time (which seems impossible?).

it's not just the apps that was just installed. It should include apps that are updated. I had this issue on SGS I when beautiful widget was having issues with updates causing the phone to use more battery power than usual

Morel likely to be a bad app, or a bad app setting causing the app not to close properly then drain power than the mere fact you restored it via titanium.

anyone one trying while sleeping, off your packet data ?
for me i tested,
2350 @100% to 0700 @ 99% (during packet data off)
If on, it will left 70% ++ in the next morning..
why is that so?

This is my battery drain using Litening ROM 1.5
I usually make and receive 30min phone call a day, push email on 2 accounts, wi-fi at work, data always on.

Turning off data packet doesn't allow any application going on line (unless you have your wifi on) and cannot download e-mails, synchronize anything, etc..
This saves your battery a lot.

Yes, that is also what I suspect. It is just to find out what which application / settings this cause.
I found out that I have 4 apps has an "sync" account, I delete all of them (except gmail), now I got a lot better performance (1 day: still 75%).

Of course the updates are included. There should be an app/good optimized app which will allow us to close the apps and thus Auto Sync and Background Data to off when we are not using them, especially at bed time. The in built task manager's RAM Clearance function is crap and frankly I haven't found an app which will optimize the RAM without force losing the apps/widgets. Tried 'Gemini App' but I doubt! This 'Sync' stuff is the main responsible part of high battery drain.

[Q] How have you improved your battery life?

I'm looking for best practices and successes rather than commiseration.
I'm running JuiceDefender on aggressive and still not getting more than a day of use (3g+BT off, wifi 2hrs, screen time 3hrs).
If you've managed to get some kind of improvement, please share what you did and how much of a difference it made.

I've installed betterbatterystats and saw that trillian causes a hell of a lot of wakelocks, so I've disabled that. My battery usage graph is much smoother and less steep but I can't put any numbers on it.

Thanks for this. I found out that it was the Smarter Alarm app, which was activating hundreds of times an hour and preventing my phone from going into deep sleep (this app wasn't a problem on my Desire HD, just on the Note).
Here is a shot of BetterBatteryStats showing 4hrs of non-deep sleep followed by 8hrs of deep sleep:

And here is the battery graph. You can see in the top left how even when the screen and services were off, the battery was still falling at an unusual rate:

An aside: JuiceDefender didn't prevent this from happening, but did heat up the phone noticably. I've since turned it off.

I've had it 11 days. My battery life has been all over the map, anywhere from 8hrs to 55hrs, depending on usage and wakelock activity. My one-day limit started about four days ago.

from my understanding of how juice defender works, i believe it closes off non-essential background apps to save battery?
the problem with this is that if the app is designed to remain running at all times, then youre only going to cause problems when running juice defender. juice defender will close the app, the app will reopen itself, juice defender will close the app, the app will reopen itself, etc. its a reboot loop for the app, which will end up draining more battery than simply leaving the background process running.
i dont recommend using any app killers. they all do the same thing and just end up chewing through your battery more. if you want to really disable an app, use titanium background to freeze it.

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. )

GSam Battery Monitor Screen Usage?

Every night, my battery is drained by 7-8% even though, GPS, WiFi, all radios are off and the phone is in airplane mode (done automatically via LLama scripts). I installed GSam Battery Monitor to try to figure out what was going on and it indicated that even though the screen was dark, it was draining the battery (and was the primary culprit). Is this accurate or is it a bug? Anyone else seeing something like this on their Nexus 4?

Mine shows 78% usage in dark.. I think that just means how much of battery total it was used while the phone screen was off. I'm taking a completely random guess here though.

So you reset the app right before going to bed and checked it first thing in the morning and in the 7 hours you slept, the main battery drain came from the screen?
I use the same app and I never noticed anything wrong. Still, battery readings are not always accurate... sometimes when I recharge my phone, it stays 100%for a few hours, then it drops 7-10% in a matter of an hour...and that's completely normal I say you shouldn't worry about it too much as long as you get satisfying usage times..

I'm not happy w/battery life and trying to track down what the culprit is. If all major services are off at night, 7-8% battery drain doesn't seem normal to me. Granted this is apples and oranges, but my iPad Gen 3 in the same configuration remains at 100% overnight.
If doing nothing drains nearly 10% over 6-7 hours, no surprise I've got issues during the day.

I've noticed the same thing, one time I didnt turn the screen on on my phone, then I went to screen and it showed 0% discharge while screen on, and 7% discharge while off. I'm running the latest version of Viper, I'm also confused and I wonder if theres some issue where maybe power is being sent to the screen even though it's not on.

After my 7 hours sleep.. Every morning my phone uses 2% battery drainage at MAX. i.e.: Wifi Edge Sync etc ALL OFF. And I am getting 4+ screen time on my phone with moderate usage. Pretty happy with the battery life so far.

Your phone probably isn't going into sleep. The Nexus 4 seems to be prone to insomnia caused by apps that don't cause a problem on other devices.
To check this download CPU Spy from the play store. Run it, reset timers to zero, and with the phone on battery (i.e. not on charge) let it rest for 30 minutes or so, then check the figures.
You should see Deep Sleep as > 90%, if not, or it is listed as an unused state, your phone isn't sleeping.
To fix this you either work forward or backwards!
Work forward:
Factory reset, install CPU Spy, run the test and see your phone is now deep sleeping.
Start installing applications one by one and after each install, run the app, then run the CPU Spy test again.
Eventually you will find the app causing the problem, all you can do is avoid that app. Note you may have more than one app causing a problem so keep checking after each install.
Work backwards:
Start by un-installing an app at a time restarting your phone in between then running a CPU Spy test. Start with any live wallpapers (even if not set to be used) you have installed, then any weather widgets. Note just un-installing is not enough, you must restart after each one.
Eventually your phone will start deep sleeping again so finding the problem app.
Hope that helps.
Regards
Phil

I tried your advice, and my phone is going into deep sleep around 90% of the time, so I don't think that it's a rogue app. I keep my phone on the dimmest setting at all times, and I only get 2.5 hours of screen on time. I have an anker battery.

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.

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.)

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.
