General Battery Usage Discussion

Hello, I'm starting this thread to actually discuss general battery usage patterns/ concerns. I figure this might be helpful for some people if not then..... =P
currently im using stock gb battery monitor to roughly monitor my battery usage, there is a mod to make the reading more accurate but i havent applied it yet...
Also... lets put up screen of the best battery life we've managed to get our phones here heee, would be fun to see =P
--
question is,
1) is it normal for mobile standby and phone idle to be ard 50% ish?
2) is it normal for my phone to stay in awake mode when i turn on the alarm

On Zeus v3n

Can't see your pics, uploaded them as an attachment to the thread.

Nice idea..
I charge my OB every night, and reboot after alarm in the morning. I dunno if it is from alarm or charging but if I don´t reboot the juice is gone in about 8 h. also battery usage app is frozen. I have this issue on every ROM, ( stock 2.3,CM7 from kang to about 60, marvell, zeus test v2.1, nova v8).
If i do the reboot in the morning the phone uses about 50% of the battery during the day (17 h). i use it for a few sms´s and calls, about an hour of websurf (wifi) and some facebook/ Xda usage..

I dunno, if in not mistaken, when you reboot it deletes your old battery stats bin but I'm still trying to understand how resetting a stat could make the battery last longer its what most battery calibration apps claim to do...
For me once a week I manually delete the stats thru cwm and yeah it does make the battery seem more resilient.....
And yeah I got the same again as my photo again, phone stays awake when I turn alarm on.... :/

I did all in my battery, but the maximum is a day and a half!
Depends on the intensity of use.
I'm using Android 2.2.2, v10a

Deleting batterystats.bin does nothing to callibrate your battery. It just stores info, like a logger. BatteryUsage retrieves the info to display it.

very good info for affirmation! thanks!
ok so calibrating battery after flashing a new rom is for??
and my questions in the op has anyone experienced the same things?..... =P

Something is causing a wakelock, what happened to you is not normal. Usually a reboot solves things like that, if it doesnt, then it will either be a rom bug or an app holding the wakelock. Use Better Battery Stats to find whats causing it.

thanks for the app recommendation found that my dialer is causing a portion of my wake lock..... and system too.... hmmmm
ok lets just say my dialer keeping my phone in a wake lock is caused by malware... would a clean install of a rom and manually reinstalling of apps w/o data get rid of the malware?
meanwhile... googling wakelocks =D

Hi, I have some experience with sudden huge battery drains and wakelocks etc. both on stock V20N and Zeus v3.2n. I did not figure out how/why it works but here are some things you can try. I did not have any huge battery drains anymore the last 24h! (on Zeus v3.2n, did not try on V20N stock)
- I have an IMAP email account installed with K9 mail and an ordinary hotmail account with the hotmail app. Both accounts are set on push and in this configuration the hotmail app causes my wifi to never go to sleep, causing increased battery drain. Removing the hotmail app solves the problem.
- automatic update of time and date settings can cause wakelock. Unchecking Settings > Date & time settings > Automatic might solve your problem. I read this somewhere on XDA.
- Use wireless networks to determine location might cause wakelocks as well. Unchecking Settings > Location & Security > Use wireless networks might solve your problem. Read this somewhere on XDA again.
As I said, I did all of this and my wakelock problem is gone for at least 24h! Now I already have 60h on one battery and still 43% left... I cannot remember the threads where I read about this but if needed I can search... Also I did not try yet whether any single thing actually caused my problem. I just killed all of it as I do not miss it I am happy. Keep me updated if you found out which one worked for you
Tip: the BetterBatteryStats app is written by somebody on the XDA forum, you can download the apk for free from some thread in XDA (search is your friend)

I think a day and a half is a good battery lifetime for the OB, if there is no app or something that drains the battery in a hard way.
I can manage to get this with the marvel rom, and my personal user-settings. Also i think every smartphone u can actually get needs to be charged around every 24 hours.

I also want to share my experience. I use the cm7 2.3 gb rom and the battery response is very bad. Battery completely dead in 18 hours. Then i switched to v20n german gb rom. It gives me better battery timing about 28 -30 hours on normal use. The i change the settings of account syncronization of gmail, hotmail, facebook etc to manual. Then there is a big difference in battery drainage. Now my battery consumed in 48 hours on normal use.

On android phones, if yours phone gives u 24 hours backup then it has good battery timing. Further you can increase the timing through the steps and trick mentioned by different peoples in this thread

Battery should last at least 18 hours on normal usage with 3G and sync with gmail , contacts and calendar. Sometimes you just turn off so many things to just make it home with some battery in it....

battery is mainly kernel related...
we need good kernels that all..

Thank you for the wakelock tips.
It seems that V20o is way better than all the other ROMS concerning battery, without any tweak. Maybe it can be further optimizet with tweaks.
A short comment: it is true that theoretically battery is kernel related issue, but in a real world high battery drain is usually caused by bad apps and other non-kernel related things.

using zeus v5.03 lite.
battery drains so much when the screen off. nearly 1 percent in every 2 minutes.
but it is ok when the screen off

Ok wasn't an sod but a random reboot, and it reset my apn settings twice when that happened

GALAXY Note: Battery life is so less. ?? (Please Help)

Hi everyone. My battery life is really sucks. I bought my item two days ago. It is new. And I upgrade my version and baseband , kernel and build version like below :
N70000XXLB2
2.6.35.7-N7000XXLC1-CL1003701 [email protected]#2
GINGERBREAD.XXLC1
I think that this version xxlc1 is last version but I wonder how is my kernel version ?
Battery life is very bad.
Moreover Charging lasts so long. 3 -4 hours sometimes.
PLEASE Help me! please

depends in the usage, rom, kernel, settings etc you are using.

when i see some kind of usage experiences, I am so jealous. How they use this much ? HOW. I only use wifi and radio.

Hi,
What is your battery life on the Note? Does it last a day even two?. If it does, then that is pretty much normal. You whine on a phone that you just use for only 2 days? Stop whining and complaining. You havent have had utilize the full charge and recharge cycles of your battery and now your whining already.. Man, give your Note a week or two and your battery life will be okay.
Hmm.. Is this the first time you use an android device? What phone where you using.before? If you we're using a non android device e.g. Symbian or etc. Then my reaction to your complains (of your Note) is justifiable. Symbian for the fact has always been known to be very good or decent in terms of battery life.
Now android OS, is known throughout (irregardless what smartphone/tablet you have) to have the AOS bug. It is a bug where there's some sort of a battery leak and hencefort most android users tend to root their phones so that they can stop background stock applications from running in the background. The births of custom ROMS and Kernels have given some tremendous wonders also especially on phone's UI and more so on battery management.
Again. Stop complaining and go down root your phone and install battery saving apps or custom ROMs. It's all over the thread anyway.
The sooner you customise your phone to your heart's content, the better you can appreciate it's full potentials.
Cheers!!!

My battery life is 5 - 6 hours. I am accept 12 hours. I wish it last 12 hours. Before I used Iphone4, it is not so long for battery life , however it is acceptable. I did not understand how notes's battery life so short.
Moreover I can not use custom rom. because they r not good as well as stock rom. ALl of them have some problems. But I can change my kernel.

to get battery life you either
a) dont use your phone or
b) get information to use your phone more wisely
So..
a) download a battery monitor.. there are a bunch recommended..
b) read the other 200 threads on battery life and dont start another one. Each and every question has been asked and answered ad nauseum
while you are figuring out root, and task killers, here are a few easy tips to help..particularly when you are putting the phone down for a while
apps>task manager>active apps> CLOSE ALL
apps>task manager> RAM> CLEAR MEMORY
settings>applications>running services> review and shut down apps/games that may be running in background (and that are not critical)
Again.... RESEARCH the forum.. the answers are already here. and you should read and post in existing threads

You could also have a defective battery.
On my iPhone 4, my first of 4 that were faulty, battery life depleted in less than 12 hours of STANDBY only on wifi, nothing syncing. Only being on. Battery life was so bad.
It's not uncommon to get a dud battery sometimes.
Try doing a complete restore, stock EVERYTHING, don't push anything (except email, cal, and contacts, you know, the basics) and see if you're having the same results. If on a fresh, stock, install you're having the same issues, then you've got a defective unit and/or battery.
Hope I've helped.

There are quite decent custom roms for the Note. I have tried many gingerbread versions (Chracks, rocketrom, cassies etc) currently on chrack's v18 small (LC1) with speedmod latest kernel.
I have not faced performance issues on this. But each user is different so u r the boss.
Best give the custom kernels a try for now. If u find the battery life better then ur problem is solved. The advantage of custom rom is that so much useless bloatware in the stock is removed for better space mgt & performance.
have provided some tips in the following link, feel free to go thru.

dude, you are ridiculing some of the well known devs who have made custom ROMS for all to appreciate and use. IF there was and is a problem on a particular custom ROM, it is or might be cause indirectly on the user itself, on what apps he/she insatalled on his phone. Surely you cannot generalize all custom ROMS have problems do you? if all have problems, the devs have some new revisions to fix those bugs and in no time at all your Note would be in tip-top shape again.
If as what you say, Custom Roms have problems.... then why the heck most people I know have used them and have big wide grin on their face to show off what they have and even posting a copy of their latest ROM pictures here... not to mentioned in YouTube as well.

ok. Which rom is the best stable than ? Which I should use ?

go read the threads on battery performance.. loading a new ROM will not fix problems if you do not know what you are doing.

first quote :laugh:
Hi there.
I had the same issues but only after the update done on ICS.
I have over 140 different application and nearly all of them have been purchased.
What happens is that, when you are not using your phone it should go to "deep sleep". This allows your phone not to run any application and merely use any battery. Your problem probably come from somewhere in your setting an automatic update. That drains a lot....
I downloaded different application hoping that it would work out such as Juice Defender, watch dog and many others. After lots of research, I found out that it is not good for your phone to have an auto killer app or even an application that modifies the functions of other applications.
So I downloaded battery spy and cpu spy on "google play" and followed the instructions.
I needed a deeper analytic application "Kernel" and this was THE application that allowed my phone to go from 6-8 hour to 28 hours.
"Better battery stats", it's not free but was really worth the spending.
Google play chronological download
1) watch dog
2) battery spy
3) cpu spy
4) better battery stats
Good luck

I keep switching my cellphone off while not using, and same goes for wifi. Using it as a secondary phone as well. It lasts only 4-6 hours.. :S I keep closing background apps, and kill app once im done with it..

Also be aware that in areas with bad network strenght, the GNote really suffers.
I normally have no complains (0,6-1,5% battery usage per hour) but where I am now, the GNote really works hard to keep the connection and my consumption easily goes to 4-6% in deep sleep and 15-20% when using it...

If you like stock samsung looks try CleaNote 3.10 , very good n battery life , I get around one day backup with heavy usage and 2 days plus with moderate usage .
If like pure google , then try cm9 , very stable and quite good on battery back up .
And if you dont use 3g or 3.5 g or any such networks then select GSM only or use 2g networks only ( Settings -> under wireless and connectivity , More -> Mobile Networks )
Also keep your display brightness to minimum , control the brightness manually instead of auto brightness .
Turn off auto sync ( big advantage over battery ) .
Scan for running apps and cached apps and force stop the ones which you dont use .
Use titanium back up and freeze some of the bloatwares ( stock samsung apps ) or uninstall them , like readers hub , mydiary , they are **** .
And dont use task killers , they drain your battery . they may clear rom but some apps restart automatically and that needs more juice than running those apps . Hope all these suggestions help . From my experience with this phone

my battery decreases 1% in around 5 minutes of use or something. Today it lasted me 10% on standby for around 8-10hours.

You need to purchase and install "better battery stats" and also install cpu spy (I'm assuming you're rooted) and use them to monitor your phone and battery in order to solve your issue. Google both and you'll find several good threads on xda about using and interpreting these apps, but if you get stuck post some screen shots from both and someone here can almost certainly help. There are a number of potential sources of such problems, generally rogue apps, and also a bug or two, but it is impossible to offer help without the details these apps would provide.

Thanks for that, i will install it. By the way i got the "battery widget" installed, which has gained popularity on the market.
Also im only using 9% of brightness of my phone.

I'm using a rooted stock 4.0.3 and I'm finding battery life its pretty good - better than unrooted GB was in fact. Simply freezing bloatware via titanium and limiting sync on some (not all) apps and services makes a gigantic difference. Design your phone around your own needs and you'll end up with an amazing device that you'll fall in love with all over again.

Battery is terrible?

I have been using my phone on wife since about 7 am. Since then, I have done maybe an hour of browsing on chrome, installed an app or 2, watch a short YouTube video, checked my email once, and played a game for 5 mins. I saw other people's battery stats and it says they have 20 plus hours of talk time? Mine says there is only 3 hours left. Is it possible I have a faulty battery? I'm also using juice defender and power save along with the brightness all the way down. I'm running android revolution hd with elemental kernel. I have the att version. Thanks in advance.

I find that based on my usage habits that I get terrible battery on Android Revolution v12. I always find myself going back to a rooted AT&T Sense build, and I'm able to pull 3 hours of screen-on time with 20% left.
Be sure to use a Wakelock Detector to pinpoint any rogue apps that are keeping your phone awake when it should be sleeping.
Also; be careful with those "Juice Defender"-type apps, Android has come a VERY long way in managing RAM, and resources since 2.2 (Froyo).
Report back with any findings

Don't mean to hijack the the thread but im having a rather peculiar issue 3g and wifi are eating away my battery like a percent for every 2-3 mins that also while only browsing web nothing else in the background can anyone help . Also im on stock rom , no root and s-off
P.S auto sync is off few apps have been disabled like (play store,facebook , google + and google search and few more)

jucie defender and power saver lol over kill i bet they are working against each other

I have about the same hours on stock rooted AT&T 1.26.502.12. Updating to stock rooted 2.24.401.1 has about the same hours, but it's only been about a week and I'm constantly flashing the new ElementalX kernels, so it hasn't settled.
Also, running at 1.2ghz and intellidemand/fiops.

what? or do u mean WiFi

you should use GSAM or wakelock detector to view if something is killing your battery, I have a very VERY good battery life specially since I updated to 2.24 firmware, i guess you don't have root

Check the ss I posted of gsm, and I do have root. Also, what does it say in talk time left in gsm battery monitor when you have full battery?

My battery life was great until i flashed new firmware. i'm on ARHD ROM and it was great on 11.5, with 12 i started using nova launcher and now battery life isn't as good as it was previously. Have you experienced changes with your battery life while using some custom launchers? Or that's rather caused by new firmware/rom/radio/etc?

if i was you I will do the following
-update the **** out of your ONE (firmware and ROM)
but since it would be to laborious, I probably do the following:
1 Factory reset, in android (backup your things becaus it will be erased if you do a factory reset in android, or just dont do it!!!!!!!!) and in recovery (or only in recovery =.=
2 Install a custom rom that is near to a stock rom like ARHD (do it two times with full wipe)
3 with titanium backup remove (after do a backup) the htc bloatware crap that you dont use
4 with titanium backup remove the gapss that you could download from playstore, like youtube, gmail, and specially MAPS
5 GREENIFY all apps that you dont use commonly, you will be able to greenify apps like maps and youtube
6 DONT USE SEEDER OR ENTROPY MODS!!!
7 DONT USE battery saver apps
8 set battery saver option: cpu, vibration, and if you can get use to, mark the data connection option too...
9 Use lagfix app...
10 download Trickster MOD and set you gobernator to MSM-DCVS (this could cause a little lag when you turn on your ONE)
allow to pass one day with you fresh rom, and the following day check how is your battery life
11 if you still have a not soo good battery life, try disabling media storage in apps configuration menu, maybe you have some corrupted media files that dont let media storage to scan all of your media and check if your battery life improve, if so, you should clean your media files, (because let disabled the media storage app have very high side effects)
optional
12 use mods related to a battery life of pimp my rom
13 disable location update from maps, and all location things from configuration (enable when you need them)
14 disable all autosync things that you could do manually, like dunno facebook
15 disable auto update hour and date
+++ disable google now
more optional sh*t
16 when your phone is fully changed in android, turn it off and let it charge until the led change to green, do that one time every two or three days
17 battery stats wipe whit any app of playstore
18 manage your brightness screen manually (its easy and fast in android 4.2.2)
fin...
normally i get 5:30 and 6:00 hours screen on time with a very good use (3g) but one day i get these results
BTW download the app batteryDrain is very good to check how your battery is draining
...And set the option in GSAM that show statistics since last full charge, and dont plug your phone because it could reset the statistics (well if you are reviewing your BLife that could be a problem since stock battery report of sense is almos usless)

[Q] Help with huge battery drain on usage [TRIED EVERYTHING]

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks

What about your connections? Do you have 3G/wifi enabled at all times?

calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now

Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal

Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

i am using greenify on almost everything.
used to use ram manager, but now i've disable it.
brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone

Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher

Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

but in aps, show good battery state :/
think that I cant trust in it ... and will have to buy a new one

if calibrate doesnt work, hardware faulty, change ur battery mate.

About 2 hours later that I fully charged, here are some ss
Just used whatsapp and opera in this time
I was thinking in change my kernel, currently I'm using semaphore 3.0 with CM10.2, is Latrop or Mackay better in battery life ?
I think its my last shot ... I'll provide a new battery next week, but i've heard some people with batt probs that even with new batt the problem persists :crying:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Using bout 2 days ... but i didnt knew about ' calibrate '. Good to know that
Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth

Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL

Greeny can also help but may need root

I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.

I loose only 2% for 7h of standby last night.

We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?

I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.
Sent from my SM-N910U

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why

Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.

Delete it pls.
