[Q] Why is "Android OS" draining my battery? [Resolved]

Here are some screenshots of my Battery Usage and as you can see my battery is just horrible:

I have done some research into the Android OS draining the majority of the battery and didn't really find anything with the SGS4G, however found the issue in the Galaxy Nexus, Samsung Galaxy SL i9003, Galaxy Note GT-N7000, and the Samsung Infuse 4G forums, and I am sure there is probably more..
Out of all those forums this is the only one that seemed like it could have a solution linking it to:
1. Google backup transport
2. Organizer widget

My only problem, I have neither of those on my phone.
I was hoping that maybe somebody here could help me diagnose the issue. For the longest time I just have thought my battery is getting old and isn't holding a charge as long, or I just use my phone too much. However after watching my Battery Usage over the past couple days makes me wonder if there isn't another issue here.
I am currently running RaverX3X's amazing Valhalla BlackEdition Final with the Booster and FBis251's bhundven's SMS KJ6 v0.2.0 Kernel. I also have installed the BraviaHack and am using the KG4 Modem. I am able to post logs or anything that can possible help. I have used thomas.raines 1-Clink Gremlin Remover following each step to the "T" with no luck of fixing the issue.
I have attached more Battery Usage Stats as well in case they might help.

I'm pretty sure it's your kernel, try antonx kernel, it has better batter life

I will have to give that try, do you happen to know what kernels are known for providing the best battery life? I guess I can always search around and see lol.

Upgrade to build3 of VB-FB which comes with beta5 of antonx's kernel plus other fixes.

I'll have to give that a shot. Right now I'm testing battery usage with airplane mode activated, and the screen off for the next 8 hours. I'm logging battery usage with the BetterBatteryStats app, to see if I can pin point the problem in the first place.

Well you may already have your answer but just incase

But really at this point it looks like its a kernel issue.
Good luck

Thanks guys, I have pretty much resolved the issue as I have switched Kernels and am no longer experiencing huge battery loss from anything other then the Display which is just plain normal. I still plan to update over to FBis251's version of ValhallaBlack as I have been keeping an eye on it, and debating when to make the switch.
[On a side note] I'm still not hundred percent sure why the Kernel was giving me this issue to begin with. If I had more experience with Android development debugging I'd love to dig deeper into this issue. However though since it doesn't seem to be a huge issue among other users in the SGS4G forums, and it is easily fixed by using another Kernel I don't really see the need.
Thanks again FBis251, and m0bstr.

Problems with Android OS with Gingerbread and Froyo
I have now encountered battery drainage problems on two different Samsung phones. For a long time my Samsung Captivate ATT running Froyo 2.2 was killing my battery. I was about to buy a new phone. I touched base with Samsung and decided to back up my phone and do the factory wipe.
After the reset and the loss of my apps, the phone seems to be working ok. Even a battery which constantly appeared to be dead, is now working fine and holding a charge.
Today another phone the Samsung Glide ATT running Gingerbread seems to have caught the problem and Android OS is using 25% of the the battery. This is ridiculous.
Normally, about 75% is for display and OS doesn't even show up.
Another person at work had an Android exhibiting similar problems today. This problem seems to be pretty widespread if I know three people with this problem. Feedback appreciated.

Maybe "One Power Guard" can help you downloaded from http://forum.xda-developers.com/showthread.php?t=1889740

Xposed + GravityBox Killing Battery

Hey Everyone,
Been an android user for quite some time and know the system well, but this has me confused.
I rooted the phone the minute it came out of the box.
I recently decided to install Xposed and GravityBox on my Nexus 5, and tweak a few things.
However, after installing it, I noticed that my battery dies much faster. And I mean, incredibly fast. If the phone just sits in my pocket for 3 hours, I'm down to about 40%. I leave my house at around 8, and have to top off my battery by noon.
I know that the issue is not the battery though, because if I go into Xposed and disable gravitybox, my battery lasts for almost 2 days.
I have tried BetterBatteryStats, but it didn't give me any unusual wakelock info. Only the normal powermanagerservice and wlan wakelocks.
In the battery menu, Android OS and Android System would use up a ton of battery with GravityBox on.
All help is greatly appreciated, since I really enjoy the features of GravityBox.. but not so much to have horrible battery life.
Thanks,
Dom

That's really odd. I've seen a few other people who also seem to be having crappy battery life with GB, which hasn't been my experience at all.

Much better than before.. but still not quite as good as without Xposed and GB.

This is me, Xposed and latest GB, stock 4.4.2 ROM. Had to reboot it earlier but it's been off charge since 7:30am. Hardly any use as I'm in work but it's not draining fast at all IMO

Just out of curiosity, are you guys running the stock kernel??? I've been running Gravitybox(and a few other modules) for a pretty good while and I haven't seen the drain you guys are getting. But I run the latest Franco kernel. With a full charge and leaving my phone untouched for 3 hours I get down to 93%. Has anyone looked for wake locks??

I've personally never had any problems with battery life on either my N7 or N5 using GB. Running stock 4.4.2, ElementalX kernel and v2.9.0 of GravityBox. Just to throw a wild suggestion out there and I have no real idea of what kind of impact it might have, or not, but I always have the newest version of busybox installed.

Yes. I stated in the op that I checked for them.
Nothing unusual.
I'm happy now though, it seems to be working on the old version.
But I would really like to find out why the battery is killed so quickly on newer versions. Eventually.. I will want to upgrade to the latest gravity box.

Sorry to resurrect this old thread, but I recently rooted and installed Xposed + GravityBox and I'm having the same issue. Has anyone found a fix for this?
I went to sleep the other night at 30% battery and when I woke up 8 hours later my phone was dead. Before installing GravityBox I would only lose 2-4% overnight...what gives?
I am on stock kernel BTW...which has always treated my battery well...

Are you sure it isn`t caused by one or more apps you installed? Have you installed BetterBatteryStats for montoring app usage/power consumption.

I seem to be getting drain also I decided to try out better battery stats it seems to be the top App doing most of the drain

[Q] Rapid battery drain

Hi all, I have a Samsung Galaxy Nexus GSM version (maguro)
I've flashed many roms before on this phone, including some unofficial kitkat roms.
After flashing one of these roms, I noticed a big impact on battery draining: down to 0% in a matter of 10 hours.
I decided to reflash the stock android rom 4.3. You know, like a total wipe, reflash everything from scratch.
Battery life remained the same, so I bought an original Samsung battery for my phone on ebay.
While I saw increase, it lasted now max a few hours more than my old battery. So the problem is not fixed.
I've tried to depict the problem but haven't found it. BetterBatterStats & co don't report a problem nor an app that is misbehaving or eating battery. Neither is network connectivity the problem: I use 2G only, and the connection is stable where I am.

As far as I am aware, it is not your typical "bad app" or connectivity problem, but something else.
Does anyone have an idea what I might have done wrong when flashing that could cause this?
Could it be a hardware problem I inflicted by flashing?
Should I follow a particular guide and reflash again?

BUMP

Okay fair enough, but flashing new roms is useless if I don't have any idea of the cause.
Also, does flashing a rom also flash other radios etc? In that case you are right this might help.
I've noticed that battery drain is equally worse even when in airplane mode btw.

Tried using franco instead of stock kernel. Now flashed Paranoid Android 4.44, no difference.
I tried some other suggestions on fora, such as reboot while in airplane mode to restrain anything from starting with data.
But to no avail, the battery drain is constant and very high.

Minimum freq is set to 192 Mhz (lowest in franco kernel).
CPU Spy reports that it has been 8:19 in deep sleep or for 94%, still had same drain :/

May be the battery you purchased is not the original one..
check another battery or you may calibrate the battery after get 100% charged

I have the version with 16 GB and 2 GB of RAM !!!

That's a huge difference, did you clean update or just took the OTA?

To tell you the truth your first result with 5.01 was very low even with that firmware.your second result with 5.1.1 is normal.after we update our rom or get a new device we should at first reset to defaults to minimise the risk of bad flashing.

I've made a dirty flash, I've no brand firmware and I have flash Vodafone firmware in dirty mode. I'm really happy for this update...

Good result!

Got a H955 on Friday. Updated to 5.1.1. Running completely stock at the moment.
Ran 3 test back to back:
1) 53703
2)52253
3) 47712
Throttling cost 11.2%
Thought to myself: Never really done back to back testing on my LG G2 - lets see what happens.
Test one was around 36000, Test two around 30000 and Test three around 29500. Throttling cost 18% The G2 was warm to the touch, and throttled quicker. I've been more than happy with my G2 for nearly 2 years.....
For me it seems the bigger problem was LG's implementation of Android at launch.

I put the air conditioning on the phone and was able to hit 57000!

I did a test again for the first time in a few days, and got 53829. A few days ago I did a test right after a reboot, but my score was pretty terrible then. It was about 43 000, I think.
Did a second test and got 50042.

Guys, if you force gpu rendering, the phones cpu gets freed up to do the more important stuff and the battery actually improved a bit too. Guessing that adreno 430 is a bit more power efficient then the a57 cores.

Force gpu rendering.. did you also force 4x MSAA?

what's the point of a custom kernal?

I am fairly new to rooting and have the op7pro rooted and was wondering what the deal is custom kernals and what the benefits are and how hard it is to use one

Its modification of the stock kernal that can provide extra features, improve performance and battery life. They all are a bit different and there really inst a better one of them all. Its all personal preference so I recommend giving them all a try for a few days and see how your phone performs.

I personally don't mess with any settings but if you happen to I recommend referencing https://androidmodguide.blogspot.com/p/blog-page.html?m=1 so you know what each option does. Also if you want to flash another kernal you can still use EXKM to manage the kernal.

Kernels allow you to modify the governor's behavior or use alternatives, boost parameters, clock speed, memory thresholds, block wakelocks, under or overclock, etc. They're often accompanied by newer drivers (ex. Wlan from CAF), Linux upstreams, fixes from QC, new features like k lapse, and so on.
CPU governors and boost can be tailored to be aggressive or passive. I'm more concerned with endurance than scores, so the latter suits me.

I have mixed feelings on custom kernels nowadays. I used to be enthusiastic, but eventually realized that every rose has its thorns. Some custom kernels are truly excellent on certain phones. Some phones just don't play nice with custom kernels, and you could lose features until you flash a different kernel. Modern Android stock kernels are stock for a reason, in the same sense that some wearable things are "one size fits all". The good thing is that kernels are super easy to flash on a bootloader unlocked & rooted phone!

Which kernal is ultimate speed? Some guy benchmarked 440,000 on atutu, I max out 380k

It is easy to flash and it has an app to change setting.

What all have you disabled/done to achieve this?

That also means nothing without the battery graph as the user could have partially charged the phone and that doesn't rest anything until the phone is fully charged to 100%. Not saying he can't get that, I'm getting 9 to 10 hours sot per charge. Just need to show the battery graph too.
