As title says guys, I don't no why but my battery life is just really bad since I moved from stock 2.1 Rom to custom ROMs :-(
Is it my phone? I can't work pig wot it is. I checked the battery usage #*#*4636*#*#) and it seems the Android system is using A LOT of it. I tried charging with phone off, clearing battery stats, not overcharging, but just can't resolve this issue.
Also, I have sync set to update manually and have mobile internet off always, only on wen needed. Same with WiFi. Screen is on auto and time off screen lock set to 30 seconds
I am using OpenDesire sense Rom
Any help will be really appreciated.
Thanks

I could feel WiFi siginal of 2.2 is much better that stock 2.1,
I suppose that the better performance will bring the fast battery drain,
if your custom ROM support WiFi N mode,
that really makes your battery life short that before.
I have the same problem and same settings as you. I read on other forum that people who updated to official 2.2 have even better battery life.
I cant even squeze 20 hours out of my battery :/
You guys should always post what ROMs you are using...
Opendesire 3.3, its the same with defrost.
i also had really bad battery life on those 2 roms
even doing nothing the phone would just keep dropping
go to official froyo 2.2
neophye roms for me have amazing battery life = 48 hrs..

Check if the phone goes to sleep correctly. Spareparts > battery usage: other usage, since last unplugged.
I had the same problem, until I found out that the phone was not going to sleep. (running and screen on percentages were way off. Almost 100% running and a lot less for screen on.
update to the last radio
I found that after forcing everything to install to SD card my battery life plummeted. There were apps/widgets that should have stayed on the phone. Once I moved these back, battery life was back to normal.
I use Systempanel to see the battery drain graph and could see a pattern to it.
Same issue here, Will try Neophyte tonight
Using this rom http://forum.xda-developers.com/showthread.php?t=741663, and it's fantastic! However batt life on .08 and .20 radio is a shocker. I watched a 1 min trailer on youtube, in and out and I lost 4% battery. Before with OpenDesire I'd be shocked if the battery percentage even twitched slightly.

I use Defrost 1.5a and I just use about 2% every hour when the phone is sleeping, and that's with auto sync and mobile data enabled. (disabled it's 1%/hour)
Always underclock to the lowest mhz when the screen is off using SetCPU and when you do use your phone make sure the brightness isn't too high.
I could make a whole list of tips, but I'm sure you'll find more than enough of those on the net.

I may be dumb but how do you force your phone to go into sleep once screen is turned off ?

When your screen is off, your phone should automatically go to sleep. Sometimes widgets or apps keep this from happening (like the music player), making it use battery as if you are constantly working on it.
How I resolved this issue was to find out what app or widget caused this. I ended up starting from a fresh reset, installing first all apps I really use (calendar/message widgets, powerstrip etc.)
I tested by installing an app, rebooting (or sometimes not), check the running time of the phone, turning screen off, and check again in 5 minutes. The phone should go to sleep in about 30 - 40 seconds. I am telling you this, because most apps causing this are widgets/apps running constantly.
However, I found in spareparts also that 'settings' was taking alot of usage time in usage statistics. A simple reboot did the trick from here on. But I am guessing I had installed something which made some app not close properly..
Maybe it is better to have a task manager/killer for these situations.
Running and Screen On percentages should not have too much of a difference if your testing and not using the phone while screen is off (music, bg stuff)
You could try juicedefender, it helps improve battery life by disabling unneeded connections while the phone is not in use
Hi guys,
Anyone have an idea what would cause my battery stats to have very high "Android System" usage all of a sudden. No new apps installed.
Thanks
I'm seeing this get pretty high as well. Starting to wonder... TW really limits the information in the Battery Status dialog. Hopefully we'll get ROMs soon that have more detailed information like I had in MikG.

It has always been a bit higher than I am used to. I just grabbed the new version of betterbatterystats from here: http://forum.xda-developers.com/showthread.php?t=1179809

Please keep me posted if you find anything
System Panel works really well for me I found. Paid version is totally worth it, too.
Just another thought/question...
I am assuming since it is "Android System" causing such high usage ( I have 5% battery left and android system is 30%), that it cant be an app I installed causing the issue.
It has to be something that is either part of the stock ROM (I am stock, not rooted) or something core to the android operating system. PLease let me know if you agree with my logic that it cant be an installed app.
Just trying to find the root cause at this point or determine if I have to hard reset which I dont feel like doing.
Thanks again
The original SGS2 has an issue similar to this.
http://forum.xda-developers.com/showthread.php?t=1290020
They discovered with it that the processor has to ramp back up to 800MHz to do its pre-deep sleep tasks, in addition to taking longer than normal to do those tasks. So with a phone that woke up often to sync, even limiting the processor to 200 MHz with the screen off, it still spends a considerable amount of time at 800 MHz. I don't think they have a fix, but you can work around by limiting the amount of syncing the phone does while sleeping.
Don't know if this is related, since TMO SGS2 doesn't use the Exynos.
Thanks for the reply. My problem is that the battery usage for android system used to be 5% or less and now out of the blue is 25-30%.
Did you change any sync settings? Setting up an email account or maybe a widget to sync could do it. The phone has to do a bunch of system related tasks when it wakes up and goes to sleep, and those fall under "Android OS", so even if it is waking up to sync for an app, the system still has to do stuff, and more than usual when coming out of sleep. Like the other thread said, the original SGSII does all these things at a far higher clock speed than it needs to, and takes longer than most phones do.
I myself don't have the phone yet, nor do I have an original SGS2, but you could look up much of the same information the gentleman who wrote up the OP in that thread I linked to see if the issue is related.
I was so annoyed with this issue that I decided to do a factory reset. I dont think it helped.
So far after being off the charger for 2 hours....I sent 5 texts, browsed web for about 5 minutes. I am down to 87%. Display time is 46%, used for 18 min and android system is 17% with stay awake time at 3 minutes, and there are other items taking up battery at 5% or less like cell standby, android os, market
Does this seem normal, I never rememver android system taking up over 5% even with little usage. I am actually pissed because I would have thought that a factory reset would have helped for sure.
BTW, I am only syncing one acct, Google
I've been watching with betterbatterystats for a couple days now. I've got Skype running in the background so I expect that to use some battery and cause some wake ups.
But it has turned out that location services and updates have been doing a lot more, as much as 7000 in one day. They show up as something related to Maps, but I think that it might be Latitude. So I have disabled that location tracking. We'll see if it helps, there isn't much more using my battery. It is just something keeping it from deep sleeping.
If this doesn't work I'll look at other location apps like weather and such. I already uninstalled Accuweather after reading about how they transfer your location tracking information over the Internet unencrypted!

Is anyone else having big battery drain since updating to JB? I used to get 2 full days now i can't get 16 hours my phone is staying awake. I'm stock unrooted using juice defender plus. Thanks in advance.
I don't get as much battery I get about 8-14 hrs with 2-4 screen in time I use to get 10-20 hr with 3-4 hr screen on time. I hope they realise a update to help fix the issue seems like quite a few are having.

Yes. I suspect you're probably having the same problem as me. Ever since upgrading to JellyBean, the battery is horrible. Checked BetterBatteryStats, and it's because of msm_otg, it's constantly hitting the device with kernel wakelocks. If I look at CPU states, my phone has been in 384 MHz for 97% of the time, deep sleep 0% of the time. Since it's not sleeping, the battery is draining much faster.
It has something to do with USB on-the-go, but I can't figure it out.
I am having opposite experience. I am getting incredible(to me) battery life. Fully charge yesterday at 430pm and this morning after a bit of texting and calls, battery is at 80%. Pretty good and should be able to get at minimum 1.5 days usage out of it at current rate.
Also, disable Google Now. That's known to be a huge batt drainer.

Thanks, we'll see how it goes from here.
Did notice my battery was draining more before JB. Once I downloaded JB my battery seemed to drain worse. Finally figured out it was Nova launcher, so switched back to TW and battery is back to normal, with google now on, mainly just get traffic and weather for now.

I apologize for posting in the wrong section. The battery drain continues even after disabling Google Now uninstalling Facebook, pandora and other apps and turning off gps, bluetooth. Andriod OS is staying awake and killing the battery. In data usage delete apps is running in the background at 43 mb? Anyone else?
For me it started with LI3 then into JB.
I noticed Media was at the top of my list when i checked what apps were using battery.
So i ended up disabling the com.sec.android.providers.downloads and so far i think this has helped get my device back to normal battery life..

I don't like any apps that are supposed to save your battery. they usually contribute to battery drain. get better battery stats and see what's causing wakelocks. it's probably location services related to google now. when you don't need it, turn off gps AND location services

I would be more concerned with partial wakelocks first, then kernel wakelocks second
enable restrictions and make sure your wifi isn't when not needed same with your Data. if you don't have 4g, turn on only CDMA data. went from 50% every 4 hours just to 15%

Exact same issue for me. I will try this.
I have had severe battery drain for a few days now. I disabled google now yesterday and that didn't change anything. My phone was constantly warm. Today, I turned airplane mode on and the battery still drained. It got down to 58%. I read somewhere in this forum that the google maps update was causing some battery drain so I uninstalled the update at 58% battery life. Three hours later I had 57% battery life. So, for now I can only assume that it was google maps that was consuming my battery. I will have to try updating maps again to make this a more concrete assumption.

Was this after you rebooted your phone?
[Sent from my cellular telephone via wireless transmission]
Been poking around here and reading all the posts that people had mentioning battery life on stock/cm11. Is battery life really that good? I find myself trying everything possible (including hardly using the device, turning brightness all the way down, turning off bluetooth & Dynamic perspective) and I find that my phone is dropping like a brick. I can have the phone lose %s in front of me just having the screen open for a few minutes doing nothing else.
I even have two apps to optimize/kill all other apps and I'm finding that this phone is dying faster than a t-mobile pre paid LG L90 I was using prior. I just don't see how people with stock and all the features on are getting more than 5 hours battery life tops. This phone dies while you use it on the charger, which is a first from any phone I've ever used.
How do your experiences stack up? Do I just have a bad unit? Really considering going to cm11 now (really wanted to like Fire OS).
You must have something wrong with the phone. I have had Samsung S3's and S4's and the Fire is far and away the best I have experienced for battery life. I am getting close on two days on a full charge although I do not use it a great deal for voice calls.

Are you keeping Dynamic perspective off with a low brightness instead of auto? Don't see how two days is possible unless you absolutely never used the device. I can lose like 10% an hour just on the browser reading text sites.
Fire has the best battery life of any android phone I've owned. I'm on fire os with a different launcher and I have dynamic perspective on (not for home screen obviously). I'm also using auto brightness. I'm rooted with gapps installed. I get great standby time and even in use its good. You should get gsam battery monitor and see what's going on, although I think you might have a broke unit.
Here is a picture from Gsam (I don't have my phone rooted). I think this is pretty bad for only 3:28hrs of screen on time and that was with the screen at the lowest brightness, not on auto. For app usage I have 7% coming from a game I was playing, but the rest of the drain is coming from system and kernel. Would really like to see another users stats with similar screen on time, as I'm pretty sure I could completely kill this phone's battery in 4-5 hours just using silk browser on Reddit.

On the off chance that you or anyone else can help me understand what's going on I ran a ~10% drain test and made a picture including information from WakeLock Detector and GSam. This drain seems very bad considering the screen was only on for a total of 16 minutes and I lost 8% power.

Your phone isn't going into deep sleep. It's hard to determine exactly what's going on there but if you download kernel adiutor (yes, that's the spelling) you'll see its locked at 300mhz most of the time. I know it sounds crazy but have you rebooted? That can often sort out a misbehaving app. Are you rooted? If so deploy greenify.

5 hours of "screen on time" is solid, the combined time incl. standby, etc. is of course much longer. He didn't know how to interpret the statistics from the device, it was a misunderstanding.

That kernel app won't help battery life but it will show you how long you spend in deep sleep.
As for greenify, you should greenify all the Google apps. I actually greenify everything except sms app, browser, phone and alarm apps.
Also, this could possibly be some kind of location based frippery. Turn location services off or onto battery saving mode if only temporarily. And turn off auto sync if it's on.
My battery will completely drain after <10 hours while the screen is off!
However I was able to find out thatquickgooglesearchbar is always the top app.
Those screenshots are a bit old but it's still the same thing, I did manage to root it today, and I was testing Greenify which did nothing even with the Xposed modules, service disabler apps just did not show that specific service for some reason. I was able to remove the widget with Xposed GEL settings but it was still running even though the widget wasn't there.
So can someone please help me out here, maybe the search bar isn't the problem but I just want some battery life.

search and install betterbatterystats (read the whole first post) and it will tell you if its wakelocks etc.
Service disabler apps will need a setting to show system apps (or something similar) ticked or switched to etc.
greenify system apps in greenify also needs to be selected. You may also need to cut wake up paths to get it to stay greenified.
You could alternatively delete the apk of hibernate it (byfar the easiest option of all this).

Your 3rd image shows googlequicksearchbox had 370ms (milliseconds) of wakelocks over a 9hr period. I really doubt that is your issue.
If it is your top app, then it is probably because of Google Now launcher listening for OK Google spoken keyword.
I seriously doubt that is your battery drain problem as almost 90% of people probably have OK Google turned on and are using Google Now launcher and only a very few have serious battery drain.
BTW wakelocks aren't the issue usually. In the past it has been "partial wakelocks" which means an app locked the device from sleeping, but never released the lock, so the device never goes to full sleep. If you see some app with partial wakelocks or if you see some app with hours of regular wakelocks then that might be an issue. Minutes or microseconds of wakelocks are inconsequential.
I suggest you flash factory image and install your battery tester only. Turn off wifi, bluetooth, nfc, cell radio. Test the drain overnight. That is a baseline for the minimum drain your device can have. Then enable what wireless stuff you normally have turned on. See what that drain is. Then start installing apps and see what that drain is.
If you have reasonable/expected battery drain with stock and everything turned off, then it is just a process of elimination to see what is causing your battery drain.
If you can't get reasonable/expected battery drain with stock and everything turned off, then you probably have a bad battery.
For the record, my overnight battery drain with everything turned off is 0-1% With wifi turned on about 1-2%. With wifi+cell about 2-3%.
IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

IMO the biggest drains for standby are wifi and/or cell signal related. Either bad signals or apps sending data in background or apps that are polling all the time.

Factory reset didn't do anything a few days ago, the results were exactly the same that was when my phone wasn't rooted, so I guess I should return the phone, and get a new one?

What is your battery drain per hour with nothing installed and all wireless turned off and everything stock?
I'd only return it if that is significantly more than 0-.2% or 1% every 5 hours.
Otherwise it is something you have installed or something to do with the signal and how it interacts with your phone.
Once you start installing stuff or turning on wireless (wifi/bt/cell) then it is no longer purely about the battery and there are more factors that need to be isolated independently.
You really need to establish a baseline to see what the minimum battery drain is. Then you can determine if the battery is the problem or something else.
If you just install everything and turn everything on, there are too many moving parts.

Okay, I now have android N, and my battery life seems to be better, I will leave mobile data off. I will see tomorrow if my battery life has changed.
Do you think I should use Adaptive brightness for more battery life?

Which battery life was the one you think you have a problem with, standby or in use? IMO for in use battery time this phone is about average. Your title of "wakelock" made it seem like you were concerned about standby battery time as it doesn't matter if there is a wakelock if the device is already turned on and in active use.
When turned on, the screen is probably the number one thing eating power, so adaptive brightness could help, but if you are in a bright area, it might be worse than if you fixed the brightness below max.
Even if you have adaptive brightness turned on, the slider scale still is useful as you give the adaptive brigthness mechanism some idea what level of brightness you feel comfortable when the mechanism detects dark, med, bright situations.
One of the worse things for eating power is for the cell radio to be turned on but have no signal, like inside office building or just a bad signal area in general. The reason is the cell radio is power efficient once it establishes signal, but when it is searching for (or loses) signal it uses a lot of power.
If you are doing a lot of disk activity like taking video or hdr pictures, it would probably help to have your userdata unencrypted as this device does software (kernel) encryption and doesn't use the fast/more power efficient co-processor.

Standby is the problem, on screen times are good enough.
Anyway, I don't even know what to do at this point. Android N didn't help enough (cell data is off), I guess I can flash Android 6.0 again and then try to fix it using apps...
What do you suggest I should do, I'm out of ideas at this point.

What is the power drain over a couple of hours with *no apps installed* completely stock, and wifi/cell turned off? What is the change when wifi is turned on?

Have you set "WiFi on during sleep" to "Never"? in the Advanced WiFi settings?
In the original release, there was a bug where WiFi would stay on even if you had set it to "Never" draining battery in standby.
Somewhere between MDA89E and MHC19Q they fixed it and WiFi will go to deep sleep after being in standby for a while, but they introduced another (or exposed existing) bug where WiFi will not resume after coming out of sleep, unless you cycle WiFi off/on. So you're standby battery should be better with this setting, but it'll be a little more annoying when turning on your device.
