[Galaxy Note 4 General] pj_rage:
I wish that these sites' battery tests included some relative measure of idle battery draw too, so I can get a feel for how long the phone will last me in a normal day.

The pure usage test results don't tell the whole story for real world usage.

Example: one phone gets 8hr of use time, a second gets 6hr use time. If the 8hr one uses 4%/hr idle (screen off) and the 6hr one uses 2%/hr, and your typical use is 4 hours, then the 4hrs of use for the 8hr one leaves 50% battery to use on idle, while for the 6hr one, the 4hr use leave 33% battery to use on idle. That 50% @ 4%/hr means 12.5hr idle, while the 33% @ 2%/hr means 16.5hr to idle. That means that the phone which had more use time, the 8hr one, lasts 16.5 total hours with 4 hours use mixed in, while the 6hr use phone lasts 20.5 hours with the same usage.

So in this simple example, the phone which had 33% better battery life on the usage test chart will actually get almost 25% less time between requiring a charge for a given usage.

There's more math to get to this next point, which I've left out to keep it shorter, but if you compare a 16.5hr period between charges, the 8hr example phone would get 4hrs usage over this period while the 6hr example phone would get 4.5hrs. An extra 30min of usage, or 4 hours of idle is what the 6hr example phone gets due to it's better idle time. I personally use my phone intermittently throughout the day, not for 8+ hours in a straight shot, so because of my usage scenario, I'd like to know the idle time so I can understand which phone will have the most percentage left at the end of my normal day. The test could be as simple as letting the test phones sit for a few hours in places with varying cell signal, such as on the reviewers desk or their home kitchen table, night stand, etc, and then record how much the battery declines per hour. If one phone regularly declines twice as fast as another when they aren't being used, I would like to know about it. Or, if they are so close to the same that it's impossible to tell the difference, I'd like to know that too.

Was worried at first about the battery will be getting it day 1 now.
[Galaxy Note 4 General] Kawaisa:
So the issue is with the Exynos version I presume?
[Galaxy Note 4 General] tmac31:
We dont realy know if there is a issue or not with exynos 1. Cuz users say you can get around 5-6 hours screen time. And these tests never show real world i doubt snapdragon version can pass 6 hour mark.

But on heaviest scenario with 8 cores on exynos probably will use more juice.
[Galaxy Note 4 General] Lodix:
This tests are from 100 to 0 % of battery non stop, in normal conditions you don't get more than 10 hours browsing.
[Galaxy Note 4 General] Kawaisa:
I hope that it's not true for Exynos users but everything points the Snapdragon winning in the battery department. Android Authority which has the Snapdragon version says that battery life is as good as the previous Note. That unbox therapy guy has the Exynos version and got like that ridiculous 2 hours on OST or something?

Also this is the snapdragon 805 done by phone arena released today
[Galaxy Note 4 General] Lodix:
I don't know what he did with the Note but that was not normal, mine can have 5 hours onscreen in a day perfectly.
[Galaxy Note 4 General] belutz:
Now it make sense why the pre order in Indonesia they will give extra battery + external charger instead the cover like they did with Note 3 pre-order...
[Galaxy Note 4 General] Kawaisa:
I remember they had the battery and charger for the launch of the Note 3 in Singapore so I don't think that has anything to do with it.
[Galaxy Note 4 General] JimmyJunk:
Have you even read this thread?
[Galaxy Note 4 General] barondebxl:
Are you kidding me? Those stats were mostly in 2days battery. 5-7 hours is definitely doable for a day.
[Galaxy Note 4 General] EP2008:
The tests from GSMarena have restored my confidence, but I'd like to know more about Exynos battery life... I'll know more next week, as I have the N910U on the way !

Note 4 battrery is monster
[Galaxy Note 4 General] alawadhi3000:
2hr screen on time with a 4.5days standby is actually considered good.

If you look at the video carefully:-

1) He has a poor cell signal.

2) In the test you saw the screen only consumed %7 of the battery usage, with the most drain (%29) is caused by the cell standby, yet he still had %13 battery left.

3) In another test he got a 2.5days standby with nearly 4hr screen-on time (including 18min of gaming) and 2.5hr voice calls with the %19 of battery left.

4) In another test he got a nearly 5 hrs of screen-on time with 21.5hrs standby and yet he had %17 of battery left.

BTW he also has the Snapdragon version, which you can see if you see his Antutu benchmark video.
[Galaxy Note 4 General] AndroidInsanity:
Is this actually true? If so how noticeable
[Galaxy Note 4 General] jdomadia:
Big differences is there between fast charging & normal, u need to try yourself to find out.
[Galaxy Note 4 General] pedmond:
I never noticed ANY difference.
[Galaxy Note 4 General] cricketgirl90:
Haven't noticed much difference in discharge speed while using fast charge.. depends how you use ur phone.. I was reading a book.. black background white text and SOT was 8hrs. Whereas when I use a lot of social media and YouTube etc then it's only 4hrs regardless of fast charging or not..
[Galaxy Note 4 General] ShadowFlare:
I think there's no noticeable difference, but I think Fast Charging just puts a bit more stress to the battery. May shorten the battery life a bit, but that's the beauty of removable battery, you can always replace it.
[Galaxy Note 4 General] kapybarus:
I have set fingerprint scanner and keyguard is top in battery drain even with screen on for 2 and half hours.

Is it ok?
[Galaxy Note 4 General] Cruzaders:
I tried to charge using and not using fast charge.

Using it I had 2.7h screen on, wifi and auto brightness.

Today I left all night on regular charging mode. Used poor 4G Internet and got almost 5h screen on time. Still 20% left.
[Galaxy Note 4 General] AMKhatri:
How true is this Theory of Fast Charging battery discharge speed.
[Galaxy Note 4 General] AndroidInsanity:
I have note noticed any difference at all. Its probably just a placebo.
[Galaxy Note 4 General] razno:
Probably is, but slower charging and less heat is better for battery. I use normal charge because charge note every night.

If I need to charge between I switch to fast charge.
[Galaxy Note 4 General] jianrong:
About 10 hours of standby receive notifications and 38 whatapps message. Drop 16% battery life. Good enough?

3220mAh is 3220 mAh no matter how it gets into the battery. You're gonna use it the same no matter how it gets in there, and one day you might have 3 hours SOT and another 5 hours. It might shorten the battery life, but that's going to happen anyway
[Galaxy Note 4 General] rpalmer92:
I'm managing about 2 days with 5 hours SOT with auto brightness and sync on and mostly on LTE. Med/heavy usage.

X-Note ROM, AEL Kernel, Greenified all user apps, TB froze apps and services I don't use.

A full discharge/charge cycle seems to really help level the battery out after a fresh ROM flash.
[Galaxy Note 4 General] Graivite:
What is your AEL Kernel settings?
[Galaxy Note 4 General] RoyLoy:
Battery drain

Hello guys.

I had the feeling that with the Quick Glance active , there is a huge battery drain . Would anyone have the same opinion ?
[Galaxy Note 4 General] Racinghart91:
i just received my note 4 today, and i been using it really heavy with system updates installing all apps and removing some, i managed to get 3 hours of screen on time on about 9 hours since i put it out of the charger.

what is quick glance ?

i saw something about that in another forum.

if i search for quick glance in settings i cant find anything (im from holland btw so it could be the language barrier)

i turned of a few apps that were stock.

i turned of pedometer from health.

sync only the things from google i need.

i did have the brightness att he highest level (and i want to keep it like that)

[Galaxy Note 4 General] Spo0f:
I have a really annoying issue which appears for second time now. Suddenly out of nowhere the phone starts to drain the battery very heavy - like 5% per hour. When I look at the battery status there is nothing which was active. The phone was not awake, Android OS or System does not have high percentages - nothing. Only the graph which is going like 45degree down.

Does anyone else have seen this?

[Galaxy Note 4 General] Spo0f:
Will try, thanks.
[Galaxy Note 4 General] acts4:12:
I'm losing about 1% per hour on standby. The culprit appears to be the Android System in my battery stats screen (android system is almost as high as the screen).

When I overlay my CPU usage on the screen com.android.systemui seems to always be on top and consuming CPU cycles. Anyone have any idea why the system is consuming so much juice?

I have disabled as much bloat ware as I possibly can (I have the at&t note 4 variant) and have location services and sync disabled the majority of the time. I don't know what else I can do.
[Galaxy Note 4 General] JAMIE1000UK:
Moderate daily use
[Galaxy Note 4 General] Racinghart91:
how do you get that kind of battery life ?

yesterday i made 3 hours of sot with 20% battery left (played simcity builder for 40 minutes)

its the third day i have my note 4, i disabled a lot of bloatware and i use greenify..

could it be that it will take a few more days untill the battery gets better ?
[Galaxy Note 4 General] acts4:12:
Hey guys. Just wanted to bump this to see if any of you had any ideas to reduce the Android system/OS usage? It's absolutely killing my battery (I've lost 5% per hour).
[Galaxy Note 4 General] Misk77:
Any screen /opinion about ael kernel and kt kernel ... Batterystat? Just rooted and I'm on echo ROM with ael kernel 5.5. Feels good, really fast ROM and kernel. Used to always end up with omega ROM+kt kernel .. Perfect combo imo. But now just try and play around.. And wonder why are people load up pic that doesn't show screen on /awake time? Like bbs screen /gsam screen? And proper information imo.. Hmm like to look at others screen but without right /true information it doesn't really say about it.
[Galaxy Note 4 General] noremac258:
I had went to bed ultra early and woke up around 1am and used my phone until it was light out. Normally I keep my Note's brightness at just passed the second toggle, and I'll achieve around 6.5 to 7 hours of screen-on time.
[Galaxy Note 4 General] Racinghart91:
How can you get those stats ???

can you tell me how high your brightness is ?

and if you use battery saver ?

i can get 3 and a half hour sot max
[Galaxy Note 4 General] michsu:
I have done an extensive test using GSAM Battery (since they have software that can measure 'since screen off').. if I set my brightness to auto, and use it for 1 min, then it will use 38% of the battery.. but if I change the brightness just under the "Location" button, then I get 15%.. This is just one of the tests that I have done.. it seems if you set to "Auto", it uses more than twice the battery for the same amount of time.. I bet you can save a hour or two of SOT just off of that..

of course, this battery test was without games.. even one game is really bad for the system because it tends to get too many push notifications out.. but I still had to put a couple of games back too (like Modern Combat 5).. :D but I'm betting it should still hold up for at least a day of playing..

Here are the attachments.
[Galaxy Note 4 General] michsu:
Attached
[Galaxy Note 4 General] Racinghart91:
hehe thanks for the reply :)

so you have the brightness allmost at its darkest (then my dreams fail haha) i like to have full brightness all the time.

i can live with 75% of brightness.

so i think 3 and a half hour of SOT is best i can get with my wishes :p

[Galaxy Note 4 General] hohoXD1233:
For some reason the Paypal app is a massive battery drain. Reduced SOT down to 2 hours!

note 4 battery life

I got this screen on time just the other day. This is with the exynos version n910h.
[Galaxy Note 4 General] BUFUMAN:
Disable it or unistall it.

Are u using this app?
[Galaxy Note 4 General] hohoXD1233:
Yeah I uninstalled it, pretty useless for me as well, some payments didn't even go through.
[Galaxy Note 4 General] hung2900:
The Snapdragon version has better battery than Exynos one right? I'm thinking about buying either.
[Galaxy Note 4 General] psycovirus:
Either my Note 4 is fake or my Battery is faulty...

I see others getting 8 SoT and full day use..

I only reply messages, and listen to music in office and the phone only last till after lunch..

2 hours SoT and 5 hour before phone ping Low Battery.

I'm using stock samsung. Very disappointed with the battery life from a punny 3220mah battery...
[Galaxy Note 4 General] Misk77:
Try to calibration the battery? And look in better batterystat and gsam what's drain your phone
[Galaxy Note 4 General] Spo0f:
I can say 2 things about the battery after 1 month or so:

1. It is inconsistent - one time it lasts for 4 days with 3h30m screen and the next time it lasts for 2 days with 2h screen. The same usage with below 15% System and OS.

2. It fails me every time I try to trust it - 2 times I've tried to last 24h with 60% without charger with me and 2 times I had to use the U. Power Saving for half of the time ....
[Galaxy Note 4 General] BUFUMAN:
Check your wake up times. Your battery curve shows me that you have to many wake up's.

Btw i had a note 3 before and it last longer without root on stock rom. But this note 4 is a disaster without root!

This fuc***g bloatware eats your battery.

-Disable SHealth! If you dont need to count your steps.

-uninstall / freez all google play apps like music video etc.

-try to unistall what u dont need!

Check your wake up's after this change's.

the picture below shows you what i disabled at quick settings.
[Galaxy Note 4 General] caja:
I had simmilar issues last month. I took it to service center and they replaced mother board. In my case battery lasted about 8-9h without usage and funny thing was that it had battery drain even if phone was switched off or in flight mode. Multiple factory resets didn't help...Try switching your phone completly off for 1h and check if you lost few % of battery. If you did...your only option is service center I'm afraid. Some other XDA members had simmilar/same issue, and we reported that in other thread in Note 4 Q/A help and troubleshooting. Btw they replaced mother board under warranty even if phone was rooted in one case.
[Galaxy Note 4 General] psycovirus:
I've Better Battery Status installed now, and will monitor it. Thanks.

I monitored closely and seems like my phone has 0 wake ups. It just never went to sleep. I'll try to disable all Samsung and Google apps.

About S Health, before i disable it, any alternative apps that uses the heart rate sensor?

I've yet to root this device in fear of losing warrenty. Unlike SGS 4 with Triangle Away, this knox can't be resetted. I'll root in future when I've bigger balls. :rolleyes:
[Galaxy Note 4 General] Misk77:
If yours not rooted maybe gsam will give you more interesting information.. But in bbs unrooted you will See screen on /wake up /sleep time if I'm not remember wrong..
[Galaxy Note 4 General] knightameer:
Today's stats..
[Galaxy Note 4 General] BUFUMAN:
Yes wait with root, until your stats are better. Like i thought device never sleeps. I didn't find another app with good heartbeat sensor.
[Galaxy Note 4 General] nh97103:
This is the best screen time I've gotten so far.

Details:

Snapdragon version on Verizon.

Wifi on almost the whole time.

Screen brightness set a few clicks above the minimum most of the time. When watching some Netflix, it was turned up to around 25%.

A lot of web browsing, Google+, Hangouts, and some Netflix.

I have a lot of bloatware disabled, including Google Now, which I can say murdered my battery when left on on my Note 2.

No gaming.

I just wish I could get this with gaming. I can't seem to get past 5 hours when gaming, which is decent, but could be better.
[Galaxy Note 4 General] BUFUMAN:
Good for this display time and this kind of usage
[Galaxy Note 4 General] nh97103:
Agreed. But like I said before, I'm not overly impressed with how this phone does with games. I'm planning on getting an extra battery kit, but Samsung has them backordered, and I want to get it through them because of the 50% off deal.
[Galaxy Note 4 General] Racinghart91:
Yo m8, can you please help me out ?

i get no more then 3hour and 30 mine of sot without gaming. Beightness set to highest. Wifi allmost all the time. Greenify donate app so disabled a lot of bloatware and systen apps. I just dont get it how people can get 5hours of sot. I mean the battery life aint bad for me compared to the i9300 but still i see people get way more out of it.

I have a snapdragon btw
[Galaxy Note 4 General] nh97103:
I'd try turning your brightness down first. Try leaving it on auto for a day, and see what happens.
[Galaxy Note 4 General] cricketgirl90:
First day back at work with my new note 4. Was on a break. My work day today was over 8 hrs. Mostly connected to WiFi. And after 11 hrs it's still 64%.

M happy.. my note 2 battery was like this. . My note 3 usually was at 30 to 25% when I got home. So it's def better than note 3. Sometimes I feel something was wrong with my note 3

Do you use Google now? And how is your Google location service set up?

Right now I've disabled google now and turned all google location off because it feels like it uses a lot of battery. I would like to use it but I don't feel like it worth it.

[Galaxy Note 4 General] Kanon25:
Was very impressed with battery life on my Note 4......until I installed Podcast app.

I was very impressed with the battery life on my new note 4......until I installed a podcast app (Podcast addict) and started using it. At which point my device went from doing two days of significant use easily, to plunging steadily down and needing charging by bedtime each night.

For example today I am not down to 20% left, have run for 1 day 2 hours, 6 mins and just 2 hrs 44 mins of screen on time. Looking at the battery stats

- Android system 19%

- Android OS 12%

- screen has used 14%

- Podcast Addict is taking 14% of battery

- mediaserver another 10%

- Andro
[Galaxy Note 4 General] nh97103:
What's most likely going on is Podcast is keeping your phone awake (which you can check by clicking on the time on battery within Battery) when the screen is off, which which should not be happening. I don't know if it's bad coding app-side or phone-side, but so far I've found three apps that cause this:

Need for Speed Most Wanted.

TuneIn Radio Pro.

Netflix, but only if you activate the thing that lets you pause/scroll with your phone while watching on a different device.

My solution is to open recent apps and close the apps that this happens with when I'm not using them. Otherwise, they'll murder your battery life.
[Galaxy Note 4 General] Kanon25:
Must be bad coding with Podcast Addict. I think I'd rather ditch it instead of running around chasing it to close it.
[Galaxy Note 4 General] 3dward87:
So you say if we use auto brightness then it will consume more power, even if we set to 0, -1, -2.. than set manually to low brightness (about little less then 1 quarter of it)

Thanks
[Galaxy Note 4 General] dynamoo:
I have almost the same results with you. I don't know if something is wrong with my phone but I can barely see 3.30 h SOT.

I have exynos verison.

Sslauncher, most of the samsung apps disabled, auto brightness, wi-fi most of the time. greenify most of the apps.

I noticed one thing that even if I sleep the phone discharge a lot, almost 20% overnight. Strange...
[Galaxy Note 4 General] caja:
Did you read my post from 7.1 about that issue? Only motherboard exchange helped me with that ;) I've tried every possible 'battery saving' tip with no luck, every possible app and toggle on/off, reflashed firmware, 7-8 factory resets... even with phone off it discharged quite a lot somehow :)
[Galaxy Note 4 General] psycovirus:
Sure, Going to instlal gsam and monitor.

Wow, that sounds troubling. I will switch it off and see if battery % drops at night when I'm sleeping. I hope this is not the case.

I have a feeling my phone discharges fast because I am always listening to Spotify (Offline Premium). But my older Galaxy S4 could last more than 12 hours on Spotify...

After disabling more apps from Google/Samsung (ie S Health, Google Now, Google Books, Samsung Apps), Switching off sync, I am getting about 40% for the same period of time, with same activity. Thats an improvement.
[Galaxy Note 4 General] michsu:
Here is another test I ran before work today.. this is manual brightness
[Galaxy Note 4 General] michsu:
Here it is set at auto..
[Galaxy Note 4 General] michsu:
Conclusion : if you are in a darker place most of the day, auto is better.. brighter place (outside) manual (not full brightness) is better..

---------- Post added at 02:28 PM ---------- Previous post was at 02:27 PM ----------

I just did the auto right now and it is darker at home.. so that is better to save battery.. that's what I mean..
[Galaxy Note 4 General] 3dward87:
Yep, I get it now what you are trying to say..
[Galaxy Note 4 General] nh97103:
For the last three days, I've paid very close attention to my battery life, and today, I tested how much different my battery life is when on auto vs. a few clicks above minimum with pretty much nothing else changed, and this is what I came up with: I lost about 50 minutes to 1 hour of screen time (maybe a little more, actually), and my phone lasted hours less all together.

For those of you that can't get above five hours screen time, I'd keep auto brightness off. It seems to do a horrible job of dimming the phone when the amount of light changes. In fact, I had to turn my screen on and off to get it to lower the brightness, which I found super odd.
[Galaxy Note 4 General] Maelik:
Moderate usage. Mostly Reddit is Fun, Chrome, and Snapchat. A little Vine and Facebook with some light gaming thrown in there.

No wifi, all LTE. (Maybe with a few minutes of 3G here and there.)
