I have used the Droid, Ally, Galaxy S, Galaxy Tab 10.1, Droid X and many other Android devices without this problem. This phone is different. Android OS has been taking up 25-30% of my batter with everything I do. Complete restore, update, custom roms, etc, nothing works. I averaged on my other devices well under 10% of my battery being used for Android OS, but this one uses a crazy insane amount and my battery is dead in 7 hours on 3g only mode! What's the deal?
That is a lot. The most i have seen is like 10%.
I only have 4.5 hours of uptime right now, but mine shows 4%.
4% here.
You have something installed that's using the "os", or some app that relies on a service that is now gone.
if Android OS is that high then you're basically doing nothing with your phone.
Try watching a NetFlix video for an hour, or else playing a game, etc.
You have to realize that your phone never actually turns off (else you'd never receive phone calls ) so that the OS has to be running.
If you're doing nothing, just letting the phone sit there idle, then of the 5% of the battery that you let it take up while you were waiting to see if it went down, 30% of it was consumed by the Android OS. It makes sense if nothing is being used that hte OS itself will be the largest user of battery, b/c, as I mentioned, the OS is still running, even if in sleep mode.
And, TBH, it actually made more sense that the old way of reporting Cell Standby was taking up 'so much' battery - b/c if the phone is idle, then I expect that the phone call monitoring aspects of the OS would take the greatest amount of battery, b/c nothing else is using the battery.
You have to take what you see in battery usage with a grain of salt. If you're not using your phone and you see a 3rd party app taking up 40% then you have something to worry about. If the OS itself is taking up that sort of percentage, it means nothing else was running ot take up the battery.
I agree with John that non-use will cause OS to seem abnormally high.
However, your 7 hours of battery life is terrible:
If you are having short battery life here’s a list of things that can help. Just read through the list and select the items that fit with the way you want to use your phone. Not all items will work for everyone and this list was written for the Droid Bionic but should work for your phone too:
- Don't use an automatic task killer--not even the one that comes with the phone. Reboot your phone and look at what's running. If anything that you've installed is running and there's no reason for it, then uninstall it and find an alternative that behaves. Ignore any stock apps that run on boot as I've found them to be more or less benign.
- Weather widgets, live wallpapers, news/social feeds, any app or service that you use that runs--do without it if you can. If you can’t do without it, lengthen it’s refresh time.
- Don't use antivirus
- Set your WIFI sleep policy to never. The default is "turn off when screen turns off". This will cause the wifi to reconnect every time you open the phone. From any Home Screen select Menu/Settings/Wireless & Networks/ and then use the Menu button to see some new options - select Advanced. Then select Wifi Sleep Policy and set it to Never. Home key to return to Home Screen.
- If you have access to wifi, leave it toggled on as it is more efficient than 3G. Wifi consumes less battery power than 3G.
- I leave GPS toggled on too by the way. Apps use it as needed. When I'm done with Maps or an app that uses it, I'm sure to return to the home screen so GPS can stop. Under wireless settings turn on "Google location services" so that an app is able to use network resources to get your location instead of GPS. I have "VZW location services" turned off--don't know why that option is even there. By the way, I increase the speed of voice output > text to speech > speech rate because I like the directions to get spit out faster. That saves a bit of battery. Turning off the display and just listening for directions help. Also, often I just get the directions and then exit back to the home screen: GPS uses so much battery I try to get it over with ASAP.
- When you get a 1) new battery, 2) do a factory reset, or 3) an OS upgrade - run your battery all the way down until the phone shuts off and then charge the battery all the way up. This will calibrate the phone's understanding of the battery's capacity. Do this once every month or two also, but don't do it too often if you can help it.
- I have my battery set to "Performance Mode" and data is on all the time because I am on call 24x7. If you don't mind, try out a more conservative battery profile to save more gobs of energy.
- Set screen brightness to "Automatic"
- Under Accounts, click on any account listed and turn off sync for any items that you're not interested in syncing. For example, Google Books if you don't use it. Don't use Backup Assistant--I prefer syncing my contacts with Google. You don't need both. Also go into your contacts > menu > display options > backup assistant > UNCHECK. Also do contacts > menu > more > settings > contact storage > and select your Google account and "remember this choice"
- Turn on Bluetooth only when you are going to use it.
- Consider turning off voice privacy. This may not be a big deal but it will save some processing (and therefore battery). It may also improve call quality.
-Turn off haptic feedback, animations, and any un-needed sounds in Android settings and in your apps
- Set your screen timeout to as low a time as you can stand (I use 1 minute) and manually turn the screen off when you’ve finished using the phone.
- Turn off in-pocket detection. In-Pocket Detection has been the source of many issues already.
- Keyboard: turn off vibrate on key press and sounds for any keyboards you use
- Use a red or black screen background. On the original Droid screen--not sure about this Bionic screen--red was the most efficient color that could be displayed.
- Camera app: I like keeping location on and flash on auto. Consider turning location off or at least returning to the home screen ASAP when using camera if location for camera is on.
- In stock browser the default home page is Google and it uses your location. This is a bad idea as it can waste your battery for no reason. Make something else your home page and make sure to close any web page that uses your location when you're done viewing it.
- Charge your phone via the wall charger instead of computer USB as it is faster. Also, don't use long USB cords--use regular power extension cords instead. I stick with the charger that came with the phone. Put the phone on charger when you go to bed every night.
- Consider install the Home Replacement app Zeam. It is basic app that uses very few resources and will help with battery power.
- Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail.
- If you are using Live Wall Papers, stop!

If battery life is still bad: Consider doing a factory reset: These have gotten pretty painless lately by following these simple steps: 1. Make sure Backup and Restore are checked in the Privacy setting. 2. When going through the setup after the reset, turn on wifi as soon as you can (assuming it is available). 3. After you have entered your Gmail account info, you will be presented with a screen that has two check boxes. Basically they are "Do you want Google to backup and restore this phone”. Make sure you check both of those. Your apps will then automatically reinstall (paid and free). Set the phone aside for a minute or two and let the apps download and install. 3. If rooted, use an app such as titanium backup to restore data only to select apps such as Tapatalk and you will not have to re-enter all your login information. I do this for 3-4 apps (Tapatalk, SPB Shell, etc.).
I've been flashing new roms/updates about once per day lately and I can be up and running with all my apps and settings back in place in less than 20 minutes. It's pretty painless now.
When I first bought my Bionic, it was eating up battery like crazy. After 2 replacements phones, I found out that some Bionic's were having an issues with Draining battery. My 3rd Bionic is great. On my original Bionic, it would take me 2 extended batteries and still could not make it through day under moderate use. Now, 1 extended battery will last me all day with heavy use.
There are some faulty Bionic's out there. It was even mentioned on Droid-Life. I think the original one they tested had issues with battery drainning really fast.

That is weird. I wonder....could it be due to actual batteries as opposed to the phones?
But in the OP's case, I doubt it - it would be too coincidental that his battery were to fail right as he applied the update.
@OP - you might also try conditioning the battery, fully charging and then running it down a couple of times and seeing if it stabilizes. It might have to do with the update wiping the stored battery stats (long shot, I know, but still)?
Well, hi guys, I have been a member on this forum for quite some time but due to bad memory I forgot my account so I made a new account, that's not my point of this topic.
I bought a new Galaxy Note and I simply love it, awesome phone, but I noticed something wrong. Yes! the battery...
My battery simply dies in 2 hours of usage (videos or listening to music while playing Wordfued)
I want a solution for that, I have my warrantry and all, shall I demand a new battery or something? I'm Swedish by the way.
And I'm sure you'll ask me about flashing a rom and root it.
I know that would make the phone faster, but I'd rather wait for the official ISC.
Only if I can do both of the things at the same time, if so then I will flash, please do read everything so you can watch from my prespective, thanks in advance.
That's definitely not normal. I get much, much more usage doing the same, so I would definitely try changing battery first and then changing the phone as a second option.

Fully agree.
I would get 4 to 5 hours of continuous use, I reckon. Some people report more.
I think the problem is with the battery. you can try this :http://www.amazon.com/2600mAh-Batte...I84K/ref=sr_1_4?ie=UTF8&qid=1329085625&sr=8-4 . Just bought it and it give me like 6-7 hours of watching videos.
Thank you for the link. I was looking for a better battery. I home to find a vendor that ships to France though.
Thank you

Thank you my dear sir, I'll take that as the second option, I'll try getting a new battery since my warranty is vailed for 2 years.
Thank you though
No need for an extra battery or extended battery.
Install juice defender
Leave brightness on auto
disable 3g (it is on by default I believe and I noticed a big savings on batt %)
disable auto screen rotate(optional)
my phone is @ 44% left , lasted 11 hours 2 minutes , This will last me another 5-6 hours.
Did about 1 hour of gaming (myth defense)
30 min browsing on wifi
45 min on tapatalk
1.5 hours on the phone
1.5 hours streaming music to my desktop via kies air
I had posted something like this before...
1. Flash and test different kernels in case of battery drain. Some are easier on your battery than the others.
2. Use Titanium Backup to freeze or uninstall crapware. This list is a useful guide as to what can/can't be removed from your system: https://spreadsheets.google.com/spr...SENVeXlqUm5vV0E&single=true&gid=0&output=html
3. Set Brightness to low value, disable autobrightness
4. Disable or scale down vibration and haptic feedback
5. Automatic syncing of your accounts is battery consuming. Sync manually if you can
6. Set screen timeout to 15 seconds
7. Disable fast dormancy (dial *#9900# and do it from there)
8. Don't keep your WiFi/Packet Data on all the time. However, if you must have WiFi on the second you wake up your phone, go to Settings/Wireless and Network/Wi-Fi settings - once in Wi-Fi Settings, hit the menu button (the bottom left one), choose Advanced/Wi-Fi sleep policy/When Screen Turned Off. This way your connection will toggle on/off depending on your screen on/of state
9. Disable location services via wireless networks - are you travelling that fast that you need those?
10. GPS is heavy on the battery, therefore use it sparingly
And don't use Juice or any other battery 'defenders': they keep running in the background and consume your juice by trying to save it. Not to mention other problems they can (and often do) create.
Hope this helps.

I have found this too, although YMMV.
I use Llama (Location Aware Mobile App) to turn things of and on when I move about. I seems to work very well mostly:
1. Got rid of useless apps, and kill all listeners on new apps so they do not pop up (require root)
2. When at home or work, WiFi is on but sleeping when screen is off (this is the one that fails most often - need to monitor), data is off (to prevent use when WiFi is sleeping).
3. When out and about, data is on, sync is off (to save mobile data & battery).
Like this I can get very flat battery level graphs when the phone is asleep, which is what I want.
When the phone is awake, the only thing you can do is turn the screen auto orientation off (I use Llama to turn it on for certain apps), and keep the brightness down, and use dark themes for everything, really. Turn WiFi off when not using it would also help.
I just wish they had made the battery larger & thinner (as someone else said) so that a thicker battery could have been more effective still, like triple the capacity
Try disabling GPS, wifi and data connections when not in use to save battery. Also you could flash the latest abyssnote kernel. It has absolutely amazing battery life.
Hello world,
I just noticed this disturbing issue. I lost about 16% battery in one night. When I looked at battery state I noticed alot of tiny little wake moments during the night.
What kind of application can cause this? Or are there any known bugged apps that cause this?

Hi
Even I face this battery issue....it is severe in my case. I hardly get 14 HRS of battery life even after about 30 charging cycles
I've installed CPU spy, I found that the CPU stays in 200Mhz, for testing purpose I had kept my cell phone untouched in flight mode for about 12hrs but still I lost more 50% of battery.
I had tested the battery by completely charging it, it just drains before my eyes . . .
I don't know if this is deep sleep issue. please help me.

My galaxy note 2 battery is draining fast and the "android os" is at about 65% at end of day and now my battery last about 10 hours. I was trying to follow your instructions above but got lost trying to find the settings to remove some tones you mentioned. Which tones are you speaking of.
Thanks...

Note 2? Wrong forum..However, to answer your question, he is talking about the tones under Settings> Sound> System.
I got 99 problems but my battery life ain't 1.
How to get the best battery life out of your Nexus 5
1. Location Services : If you are not in a neighborhood with a lot of wifi spots you will most likely feel this draining your battery life. Under settings make sure that Location Services is set to battery saving and not High accuracy.
2. Widgets : Weather widgets, games eat battery by constantly fetching information . Check the settings for these widgets and make sure they are using wifi and not updating the weather information every 30 mins or so. I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

I keep my settings to update weather information every hour to keep it reasonable. The Gmail widget sometimes eats your battery too. I removed the widget and used an icon in the dock at the bottom to check my email.
3. Restart your phone : Sometimes residual processes from closed apps could cause issues. Restart your phone if you haven't done it in a while and it should clear up any unnecessary things.
4. Keep wifi on during sleep : I made sure my phone uses wifi even when its sleeping. 3g / 4g eats the battery like crazy if you turn off wifi when your phone sleeps. This should be a default setting as pointed out by some users. In my case it had been changed probably when I was tinkering with the phone. You can find this setting in the Settings -> Wifi -> advanced -> Keep wifi on during sleep.
You can also use apps like Greenify , Tasker , and Llama.
5. Don't use Automatic Brightness : Turns out if the sensors are constantly looking to adjust brightness it takes up more battery. I set my brightness at around 60% and it works just fine throughout the day.
6. Use wifi over 3G/4G/LTE if possible
7. Switch off wifi when using Data: Android doesnt switch off your WiFi when you use data because Google wants you to use it for Locations and help build their database of networks.Switch off WiFi completely when using data to save a good chunk of battery.
8. Turn off Vibration on touch : Typing uses quite a bit of battery over the course of a day. Try switching Vibration on touch off.
9. Use Franco Kernel: : This will require rooting your device however it makes it a lot more power efficient.
10. Turn down the Facebook refresh rate : Make sure it updates not very often( every 3-4 hours) or never. IMO your phone is better off without Facebook or any other battery hog social networking apps.
11. Greenify: Works with and without root. Use Greenify to hibernate apps when they should not be running in the background. This is best used for games that fetch information about deals or daily events (i.e. Battle Nations or Real Racing 3)
Feel free to add anything to my list.

4, 6, and 7.. it would all depend on your signal quality. i get MUCH better battery life on lte than on wifi. and i mean much! i get 5-6 hour screen on time without doing anything special. on wifi i get an hour to hour and a half less. so the wifi thing is just in your situation, and not for everyone.
9.. there are better kernels than franco kernel. and on top of that, kernels have so little influence on battery life. battery life is mostly about your personal use, your personal setup, your choice of apps used, and very much on the quality of your phone/data connection. everything else has very little influence, including kernels.
3. This I agree. I've had super strange battery drain if I don't restart the phone once in a few days. I refuse to believe its a bad app as there are no wakelocks, seems to be more of a phone idle battery drain or radio drain.
4. To be honest, it depends on the WiFi network. Some WiFi networks (typically at universities) have a strange and outright horrible battery drain the moment you connect to their network and leave the screen off.
6. Again to not repeat what I said earlier, I get better battery life if I connect to LTE instead of my school's WiFi. Download speeds over LTE are 2-5x greater than my school's WiFi, so race to idle may be happening here.
7. Most android phones today have minimal battery drain with WiFi left turned on. But it doesn't hurt turning WiFi off if there are many weak known WiFi networks around you.
8. Not sure how much you'll save, I don't even recall much of an increase of battery with this off. YMMV situation I suppose.
9. I've had better battery life with other kernels. Again it's a YMMV situation.
Not a bad guide really
Another tip is that if Google Play services keeps your phone awake for a long time, revert Google Search to an older version, reboot the phone. The wakelocks should be drastically reduced.

Using Nexus 5 with:
CyanogenMod Nightlies
ElementalX kernel
1d 2h 9ms on battery / 2h 17ms screen-on time / with 38% remaining!
Good information! ?
Only thing I'd say is to just remove the part about kernel completely. As said above, kernel makes little difference. I get 24 plus hours and 6 hours screen time on any ROM or kernel. It's all setup and usage.
Nothing new here. Good for noobs, but most will have done this already
I have found that turning location off completely has helped my battery life tremendously. While I was barely able to make it through the day before, now I can easily pass by with 40% or something and light usage. I've tried other things but nothing has improved my battery life as much as turning location off.

Yup! That's what toggles are for. Need it? 2 clicks and its on. That's always my advice.
Sorry for the long list of screenshots above, and also for creating a new topic, but didn't want to spam the normal board for battery discussion.
Anyway, I have the N920I model of the Note 5, using it on Telkomsel in Indonesia, and getting average 3+ hours SOT on this device, which I think could stand to be much better, given I got around the same figure on the Moto X 2014, which has significantly worse battery life according to most counts.
Here's my settings:
Screen brightness 60%, auto
Sync on
NFC off
Location high accuracy
Bluetooth on from 8 to 3.30, then off for the rest of the day
Connected to an Asus ZenWatch 2
Wi-Fi on from 4 to night, from plug out in morning to 8
Here's the list of apps I disabled:
And here's how my usage goes:
* Plug in when I wake up, then out at 7-ish.
* Get to school and let My Places switch to "Work" mode, where it changes the Bluetooth, Wi-Fi and power saving settings and turn off data before starting the first class.
* Turn it on between classes to check for new messages.
* Leave at 3-ish, and get home, letting My Places change the settings back to normal. At this point, the phone is usually at 70% with an hour of screen on time to report.
* Use it periodically throughout the rest of the day, switching between WhatsApp, Snapchat, Netflix, Chrome and YouTube.
* Plug in at 8 or 9, then plug out before I go to bed, topping up what's left in the morning.
It's a fairly light usage pattern, which reinforces the point that this phone should get more than just 3 hours. Any specific app you're seeing here that might be putting its toll on battery life, or a specific setting that you can advise enabling or disabling?

Just try counting how many threads there are about battery life in this section. A lot! I, being one of the victims of horrendous drains, have tried everything. If you keep the device relatively clean(software) and it still drains then there is only one thing you can do. Wait for the marshmallow. I'm sorry but that's what it means owning a samsung device.
try gsam battery monitor. It may give insight into what is going on....

Already did! But Android OS is always the top consumer.
thanks!
As Octa_core mentioned, there are quite a few threads about battery life already. They might be of benefit if you haven't already looked through them.
Here are a few things you might try, if you haven't already.
- Turn off location high accuracy, or only turn on location when you need it (if you can)
- Turn off location history
- Turn off Always Allow Scanning in Wifi advanced settings
- Turn off S-Pen settings (alerts, sound, vibration, detection)
- If using Google Fit, disable activity detection in settings (this definitely helped my idle drain)
- Turn off anything you don't need to sync on your Google Account
- Disable enhanced LTE services
- Turn off Motions and Gestures you don't use
- Set touch key light duration to Always Off (under Display)
- Turn off Smart Stay
- Set Screen Mode to Basic
- Use a darker theme
- Try disabling some apps, especially S-Finder (may require Package Disable Pro to disable some apps)
- What does your signal look like in GSam? Some drain may be due to poor signal.
If none of that helps, then uninstall or disable (probably will need Package Disable Pro to disable) all apps you installed, and I also recommend that you disable S-Finder. Turn off all radios (location, NFC, bluetooth, wifi, even data) other than cell. Reboot after those changes. Monitor and see how idle battery drain is. After I did this, my idle drain was around 0.4% per hour. Then you can gradually enable radios/apps, only 2-3 at a time, reboot, and see how it impacts idle drain. Continue until you find app/radio that increase idle drain.
