Is this battery usage normal? - AT&T Samsung Galaxy Note 4

In 3 hours, mostly standing by, it drops to 87%
I have no idea why "Android System" gets 23%

well, if you're not using the phone, with apps or whatever.. then something else has to take the place of the 'most used' application..
I hope this isn't the "omg android system is using all my battery" again that I seen all over the gs2 forums when it came out
attached is a screenshot of my battery usage, I been streaming music all day at work.. mostly wifi, screen on a generous amount of time.. browsing xda, internet.. even played around with autodesk sketchbook..

Just got the phone today, it's been ridiculous. I've recharged my phone from 20% to 95% twice today. Granted, I've been using it non-stop
Now at 65%. Just terrible!
Android System 38%
Screen 20% (time on only 2h 5m)
Android OS 11%
Facebook 8%
Cell standby 5%
I had a lot of sync crap turned on that wasn't on my note 3 (like auto sync photos to google cloud), as well as some other settings that I just turned off like AT&T Address Book, and several google sync services I have no need for. Hoping that fixes it, I'll know tomorrow!
Android System.. that is where it would be syncing photos, right? I'm thinking that must've been it.

I've noticed that is phone really really wants to have full gps on stand by at all times.
Can't wait to get that battery update. But when that happens maybe never

A background process is eating your battery. I have gotten over a full days use with 3 hours or more of screen time and still at 35%, that or you got a bad battery. This phones battery life is incredible

Since I just got my phone this morning, I will have to report my batter usage later.
However, the phone charges SUPER FAST!

I'll tell you when it doesn't charge fast, I plugged it into my S3 charger last night at 11% and it still wasn't at 100% when I woke up about 9 hours later. Yesterday I got 3 1/2 hours of screen time after starting at 70% when I actually got the phone around 5 pm. The phone was under HEAVY use (downloading updates on LTE, customizing, etc.) I'll be interested to see how it does today under mostly normal conditions.

Glad to hear you feel that way! Thank you for the glimmer of hope! I have a feeling you are very right, and that it could have also had a lot to do with the huge amount of downloading I was doing yesterday. Today should be a much more normal day of use. I'll check back in a bit.

My battery went from fully charged to 94% in a matter of minutes just using the Internet. I decreased the screen brightness and removed the sync from some apps. If I don't see an improvement before my 14 days is up this is going back.

I also realized power saving mode was not enabled. After enabling that and disabling all unnecessary sync services, I'm stoked.
Usage seems to be great now, too.

You shouldn't have to use power save to get good battery performance. You definitely have a bad battery

Really? It seems pretty good to me now.
Is there a wake lock detector you would be able to recommend? Looks like it needs root?

I let my battery completely drain where it cut off at 1% and let the battery charge fully. Powered it back up and made sure nothing was syncing that I didn't need and now the battery seems to be performing better then before.

Either you have fast charging turned off or something is wrong with your charger/battery. turned off my phone charged 0-100% in 79 mins.

Yeah, his phone is broken or misconfigured if it charges slower than a Note 3. I've owned both, and the note 4 charges WAY faster.
Sent from my SAMSUNG-SM-N910A

I agree it is very noticeably faster. N3 was decent already with the provided charger, but N4 charge blazes.
Kinda want to get that Qualcomm fast charge 2.0 car charger so I can charge from 12v sources. The standard usb 5v 500mA regulated charge is pitiful

I have to constantly kill Index Service. It's loading CPU up to 100%. There's a bug since at least Note II. If you have large PDF files or many files of any kind, it will never finish indexing. Some reports link it to 64GB cards, but mine does it even without the card.

Holy bad battery life Batman!

I'm on Stock 2.2 US and Battery Life is HORRENDOUS. I have the Moto Charge app that displays actual battery in the status bar. I charged to 100%, wiped battery stats, turned it on and after 6 minutes of no use, I'm at 97%. What am I missing here?
Are there any apps constantly running in the background?
Do you have bluetooth/wi-fi/gps switched on all the time?
Are you using your phone somewhere that's unusually hot, cold or humid?

No, no, no, no, no
How long have you had it?
Has the battery always been this bad?
Has it only started recently? Is there some sort of cause, something that happened that has brought about this poor performance?
I just got the phone from a friend but I do not believe it to be an issue directly related to this specific handset.
Having GPS "on" all the time will not drain your battery as it is only being made "available" when an app needs it (mine is always checked and has zero effect on the battery until actually used). Did you do a factory reset after installing 2.2? On the Moto forum many issues are resolved with a reset.

Lithium-ion batteries have a big drop off at the start of the discharge profile.
They will then maintain a fairly steady state between about 80% - 40%.
A 3% change, therefore, from 100 to 97 is not equivalent to a 3% change from 80% to 77%.
I'm pretty certain it is specific to your handset - most Defys have very good battery life.
Here's my handset:

At that rate, it should last ~5 days.
There are always something running in the background. Install a cpu monitoring application and see if the cpu is running wild.
In my case, 1% power lasts for 3~5 minutes usage (game, movie, surfing etc), or 2 hours standby (wifi off), or 1 hour standby (wifi on).
I checked Battery Use, there is nothing crazy. I've also checked Battery History and nothing is using the CPU or keeping it awake. I actually wiped the phone last night, didn't have a sim card in it and left it on over night and it lost 14% in 7 hours. It shouldn't have even lost 2% given that it wasn't connected to a cell tower. I have wiped it twice.

I am of a differing opinion.. I think these android devices have terrible battery life.
That being said, invest in a few of the cheap Hong Kong 1800mAH batteries on ebay.
I had a good experience ordering from "farmerseller". Curiously, I ordered 1500mAH batteries but received 1800 mAH batteries..... it took a while to arrive, but they work great and the charger is nicely designed.

Compared to what?
What's your frame of reference?
I'm not aware of any other smartphone with specs similar-to or better-than the Defy's that gets anywhere near the battery performance my phone does.
Everyone I know with Galaxy Ss or Desires charges basically every day, one friend with an iPhone4 can get a couple of days out of it but most are only a day, friends with Blackberrys get a couple of days or so.
I regularly surpass 3 days of what I would call normal usage - web browsing, texting, a bit of gaming and the odd call here and there.
Are there any ROMs known to get better battery life? On both my N1 and NS, certain ROMs performed LIGHTYEARS better than other ROMs in the battery department. This is a well known fact that Android is inconsistent on battery life.
So I wiped, re-wiped, flash the beach update.zip, wiped, re-wiped and I'm not confident the wipe is working. http://forum.xda-developers.com/showthread.php?t=988036
Regardless, I also find it odd that my battery was at 85% and, after the flash/wipe, it charged to full in <10 minutes.
Give it a few days of usage and see the results afterward. Basically it needs some cycles to re-create the battery stats after wiping.
You can also install Powertutor to check what apps are "consuming" the battery.
From my experience: with light usage I made once 3 days but normally 1-2 days is all I get (3g, some talks, 30 min browsing, some ebook reading). It was the same with my past 2 Android phones and some 4 Win Mobile phones...
When you are in a really tight spot do the usual tricks: 2g only, disable APN, don't play too much with the phone. You will probably get 3-4 days in one charge
I updated to 2.2.1 also, and battery life went right down the tubes. I lived with it for two days, and then did a factory reset, and now I have better battery life than with 2.1. I really didn't want to factory reset because of all the fine tuning I did, and not to mention re-downloading all the apps and setting them back up, but I must say it was worth it. After 13 hours I'm at 30%, and that is with heavy use. I started at 100% and in 10 hours without using it much at all, it only dropped 10%, so 1% an hour I can live with. Once I started playing game it went fast, but that is to be expected.
Ahhh!!!!! You guys are killing me from laughter. Don't take this the wrong way....but read more items on these forums...they are a welath of information. First off.... battery stats are wiped. It will take a few days of charging/discharging for the phone to get an accurate idea of actual use. It needs a baseline created. Don't worry yet. It can take up to a week to get really good stats. As for the horrible life on 2.2....did you wipe battery stats before flashing? If not thats your problem. You have to wipe the stats when you go to 2.2. Different profiles and usage. It's mentioned in a number of the roms. With steady hard usage I'm averaging about 2 days between charging. On standby with no use the best I have gotten so far is 6 days. RTFM.... Hope this helps out.

Greatly improved battery life (CDMA)

Last night I restored my phone using the factory image. For some reason I anticipate an OTA soon so I wanted to be ready. Anyhow, before I suffered from the battery drain bug. I forgot to charge my phone last night, and didn't realize it until I got in my car and put it on the car charger and it said 89%. My first thought was that my battery drained over 10% in the hour I was getting ready and not using it! Then I went into battery settings and found out I never charged it.. then I found some pleasant... well, I'll just show you.

As you can see, I lost less than 5% battery during the 6+ hours my phone was unplugged. I had the phone in the living room charging while watching a movie. Then I unplugged and used it for about 20 minutes in the bedroom which accounts for the first rapid drop in battery. But after I set it down, the phone went into a coma. And I can't see exactly, but it looks like it was only 2 or 3% which is great!
Not sure what changed, I still have the same apps installed, even Facebook. I did, however, NOT disable VZ backup assistant like I normally do. Maybe that is what causes the OS to go bonkers? Thoughts?

I got about 20 hours out of mine yesterday (extended battery) with moderate usage (texting, ebay, facebook, web) This is after unlocking the bootloader and rooting. Unlocking the bootloader resets the phone to factory state. I've read a few other posts around the web where battery life is greatly improved after a factory reset. Android OS is still the main things devouring my battery, but I almost don't care with the performance I'm getting. I should also mention that I wiped battery stats from CWM and then calibrated the battery on first charge.
I'm no dev, so I don't know why a reset would help. Then again, maybe it was wiping battery stats and calibrating that helped me. Just my $.02
How did you calibrate the battery?
There's a free tool in the market that will calibrate for you. Have to be rooted though. Just search for calibrate.

Guess maybe I'm one of the lucky few...I've always had this type of battery life. The phone just sips power while the screen is off.
While it is on...well that's different. I keep the brightness high and get about 2-2.5 hours of screen time before it powers off.
The interesting thing here is that it seems that you have the Android OS constantly waking up the phone but yet it still barely uses battery.
Do you have location services turned on or off?
Turned on. I noticed that too but the overall awake time is low. Usually it would be over half of the entire time on battery, sometimes 100%.

I used 50% in about 3 hours on my extended battery.
fml.
Great battery life, but you didnt really use your phone much.
Your "Screen on" is only about 15% of those 6 hours. Which ends up being about an hour.
Still, none the less, great battery life/power consumption.

I think you missed the point. I said this was done while I was sleeping. Many people are experiencing extreme battery drain even when they aren't using the phone, as was I. After restoring from the factory image, my issue seems to be gone.

I unplugged my phone at 11:30 pm with 98%, woke up at 7:30 am today and it dropped to 76%. So a 20% drop in 8 hrs with the phone just sitting there with wi-fi on and no apps running. It'd be very interesting to see if a factory restore would help.
How's the battery life now that you're using it?
Im thinking of unlocking and rooting mine tonight. havent had a moment to read the walkthrough just yet.
i noticed this too last night/today. i went to sleep after installing bugless beast 4.0.3 cdma, left it off the charger, and today i saw the chart was pretty much a flat line. i don't recall the exact times, but i'll try to time it out. about 8 hours
i wonder if all the initial extreme battery drain reports are due to the 'wowanewphone' effect, where you are molesting your phone 24/7, as opposed to the typical day-to-day use you'll eventually fall back into

Battery life + great battery monitoring application

I just got my Glide a few days ago. From the specs of the phone and reviews online I was expecting the battery to last very long, but that hasn't been my experience.
My battery was going down about 10% every hour which means I would barely make it through a work day without charging it again.
I found a great app called Battery Mix that tracks battery usage and estimates how long the battery is going to last. It shows a number called P/H (percent per hour) which tells you how many percent per hour the battery is going down (or up if you're charging). You can find the app here: https://play.google.com/store/apps/details?id=jp.smapho.battery_mix
When I first installed the app I was getting about 12.5 P/H which means the phone will only last 8 hours. I then uninstalled a few apps that use battery, but that didn't help much. Somebody said their battery improved when they formatted their SD card, so I just removed the SD card from mine. Now my battery consumption is down to about 8 P/H. The best I've seen is 7 P/H. This is better but still would only get me 12 hours and I'm not running all the apps I would like to be running.
I have JuiceDefender running now on the balanced setting. I'm running the Osimood ROM with Android 2.3.5. I've removed all background network polling apps like Facebook. Android OS is using 56% of the battery followed by display at 15%, so there isn't anything else that's eating up my battery.
How is the battery life on your Glide? Could you please install this app so we can compare numbers?
Woah, 56% battery life for the Android OS?
On daily usage it barely gets above 20%. The screen takes most battery life.

Thanks for the info.
Mine has been sitting on standby most of the day so that's probably why display is so much lower on mine than yours.
The high percentage of Android OS doesn't really worry me. It doesn't mean it's using a lot of battery; it just means it's using most of whatever is being used which could be a small amount.
Mine is doing much better now. P/H is down to 4.3 which means it could last 23 hours.
I really think the problem was the SD card. I'll pick up a different one after work today and see if it works better. I need a bigger one anyway.
I also found a thread that talks about corrupt image or video files on your phone causing bad battery life. That could definitely be what I'm experiencing. Should be fun figuring out which image is causing the problem.
what about downclocikng your cpu to 800? it will help i belive.
OK just installed it. I will let you know how mine is doing in a few days. I am fully Rogers stock.
I replaced the SD card and it seems to be doing better now. There may have been images on that card contributing to the problem.
I actually had GPS, wi-fi and bluetooth on the whole time. I've turned them all off now.
I've also underclocked it to 800. Thanks, taiber2000.
It looks like for the last hour it only dropped 3 percentage points.
If you are rooted and have ClockworkMod installed, you can sometimes get better battery life by resetting your battery stats. I think there are even some apps for rooted phones that will do it, but I don't have any experience with them. I can say, however, that resetting my battery stats using CWM increased my battery life significantly.
See here for one guide on how to do it: http://www.droidforums.net/forum/bugless/111009-get-better-battery-life-reset-battery-stats.html
sjbotha your welcome.
i belive i will do the same when i'll get my phone as well. altugh i will install the OC rooted kernel for better overall performance i will still downclock via software, not need the extra sterngh for my uses and i better have longer use time then CPU power.
I get 4.9 but the other day I was getting 12. All I did was Reboot my phone and I haven't started many apps. I think when they start they stay in memory.

Mine depends on usage:
-about whole day wifi-on with 3 hours games and calls; if battery is 100% at 6am, it will be 20-30% at 10pm
-whole day HSPA+ on, 2 hours phone calls + SMS/MMS, emails etc; if battery is 100 at 6am, it will be 50-60% at 11pm or before I sleep...
in terms of P/H:
-i get 3-5 P/H when wi-fi, Auto-Sync is on.
-i get 2-4 P/H on HSPA + Auto-Sync on.
-about 1-2 P/H or sometimes a straight line on Battery Stats when Idle, no data connection and/or auto-sync is on.
in other words, the glide can handle my needs in a whole day without completely draining it's battery.

Battery Life Problems

How's everyone's battery life? I get down to about 5% by the end of the night with light to moderate use and standby time seems to be pretty terrible (5% drain an hour or so).
I checked in the battery info and it shows Android OS at the top with 66% use and when I click on that, it shows Keep awake at 3 hours and 49 minutes.
Anyone else having this problem? I did a full wipe and that didn't fix anything. I'm also running the latest update.
I can usually last a day with moderate to heavy use. Haven't found it to be any shorter than that so far. Try turning on the processor eco mode
I wake up at about 7:00a.m. and go to sleep at around 12:00a.m. And I usually go to bed with about 30% and this is with moderate use, with full brightness and eco mode off.
My battery life is pretty atrocious as well compared to my Evo LTE.
I'm at 40% at the moment after 7.5 hours. That's mostly wifi and without 4G. Have tried keeping the screen at 40-50% brightness, eco mode on, quad control, on, etc.
Even tried cycling it a few times by letting it run all the way down and charging until 100% with phone off and it's there's been no improvement.

I have been surprised at the battery life of this phone. I was annoyed after I bought it because I didn't realize it didn't have a removable battery and I typically buy extra batteries. I gave it a try though and yesterday I used it moderately while at work for 12 hours, used it for streaming audio on the way home, and after a total of about 14 hours without charging it was only down to 70%. Eco mode was on, and screen set to 67%. Periods were with 3g, 4g, low signal, and wifi.
Dont know why you would have such bad battery life, i used my phone all day yesterday from 530am til i went to bed last night at 1115pm only 30% discharge at that point , i dl a rom on it for my gs3 when i was going to sleep 789mb and woke up this am to 36% bat left. I am truly pleased with the performance so far.
I am not a light user either and use it to play need for speed , I haven't even put it in eco mode yet.

Honestly no complaints so far. I've been toying with it for fifteen minutes after ten minutes of music play and it only now went from a hundred percent to ninety nine. On my 3d it would be down ten to fifteen percent by now.

What percent of the battery usage is "Android OS" for you?
This morning I pulled her off the charger and browsed reddit for an hour with the screen at 63% and lost more than 20%.
I'm exchanging it and if the new one doesn't work any better I'm probably going to sell it and go back to the Evo.

What percent of the battery usage is "Android OS" for you?

At the time this was done it was at about 40ish%.
At the moment I am at 25% after using my phone about 16 hours. Android OS is at 51%, screen at 19% with about 3 hours clocked in.
By this point I expect a minimum of twelve hours on the battery with at least two hours of screen on time. Im very happy with that if I use the screen for more than two hours it'll last about eight hours which is still good. This phone idles very well I expect it improve with future updates as well.
To the user who s getting a lot of fc's, I definitely don't get any and that's saying a lot for stock software from lg opposed to stock android. Don't install task killers of you have one

I'd say your battery life is pretty poor.
My battery is a little bit better. I don't have any screen shots right now, but it's usually around 3 - 3.5 hours on screen. Around 7-8 hours battery usage total.

Try downloading Gsam or watchdog from the playstore. Watchdog will tell you if there's a rogue app draining your battery and Gsam will tell you what's taking up the most power.
let your phone do a 3-4 recharge discharge cycles..then it would stabilize.

what is a recharge discharge?
charge it to 100% then let it discharge(1 cycle of rechrge of discharge) although there maybe a better word to represent that(noob in complex english )..

With 2 hours screen on time over an 8 hour period and your steady curve on that graph, I would say you have some app, or some service eating CPU cycles constantly (these are called wake locks)...
Do this:
Download an app called CPU spy
Charge your device all the way
Pull it off charger
Open CPU spy
Then just hit the back button to close it.
Let your device sit for about a half hour. Don't touch it as much as possible. Leave the screen off.
Open CPU spy... post a picture of what your CPU stats say according to that app. Majority of your times should be in deep sleep mode.
Also, your battery shouldn't drain anymore than 1 to 1.5% each hour at idle. Unless you live in an area where there is poor reception (scanning for signal chews it up as well).
EDIT** ALSO...is your screen brightness on auto or is it manually adjusted a little brighter? If it on auto, then your battery life according to those graphs is absolutely awful. I have mine set pretty bright and I still see about 3 hours of screen on time

			
				

			
				

			
				
Give it a few hours of "normal" use and then come back here with a Betterbatterystats screen shot with Partial Wakelocks/Since Unplugged and Processes/Since Unplugged. That way we can see what is eating your battery. With only 4% gone, we can't see anything (too small of a window). Make sure you don't plug it in and use normally.
I have seen your other posts and I am wondering what it is that you really want out of your battery. If you think that you can get 3-4 days out of a charge, that is not going to happen. 1.5-2 days is a reasonable expectation and I think that you can get that, but you have to look at your usage habits. No kernel is going to fix that. No ROM is either.
If you are polling notifications (Facebook, G+. Twitter) or Google Locations (Maps, some app that requires location) or believe it or not using the XDA/Tapatalk app a bunch, then those will drain your battery quite fast. I use the Tapatalk app quite a bit and that and Google Now are my #1/2 battery drainers. Could I get rid of Google Now? Sure. It is more of a novelty at this point. I still get 1 -2 days of charge on my phone wihtout worrying about where a plug is.
Like I said, come back at the end of the day or tomorrow morning and post the Partial Wakelocks/Since Unplugged and Processes/Since Unplugged and we'll see what is draining your battery.
Another thing to note is that it seems your mobile network is typically pretty patchy. This can really drain your battery too.
I've been chasing wakelocks since I got my device and think I'm at a pretty good place. I get 2.5-3hrs of screen on time (about 20% screen brightness) across about 25hrs of standby time. Does anyone else get a lot of mmc1_detect and mmc0_detect wakelocks?
thanks woodrube. I will post my stats at the end of the day. I don't have a facebook or google + or any app that have notifications or updates by itself. I have the screen set to 20% brightness

			
				
how do I delete that dmux wake lock?
