You never had that problem because Note2 had only 3G antena, and 3G is everywhere. LTE / LTE-A is really rare ( in our country :D ) I do not use mobile data at all - wifi at home, wifi at school :) So i switch to ONLY GSM - this have signal on mars maybe :D GSM has about 30% lower power consumption than 3G and phone stays on it permanently - no more signal/ antena / 3G - 4G trolling - better battery life.
[Galaxy Note 4 General] podface:
Ah i think you are right!! i put it on airplane mode and no more battery drain!!
[Galaxy Note 4 General] alex989898:
I found that when I'm on a very poor signal area, my phone doesn't IDLE which is not normal.

Hi

is there some fixed test to see how good the battery is ?

something like to run at full brightness a video or something like that....

i charged up my battery 2 days ago and am using the phone light / moderate use... bit of internet / snote and mostly leaving the screen on using the phone as a digital photo viewer when i am working.. i have gallery open with a photo displayed..

Currently i have Screen time on at 14 Hours... about 6% left on battery...

would like to find some fixed test to check my battery

We all need one of these bad boys:

http://www.ebay.co.uk/itm/Extended-...-Samsung-Galaxy-Note-4-IV-N9100-/201200938088

45000mAh in a standard battery. Wahooo!!!

:cool:
[Galaxy Note 4 General] ShadowFlare:
You put an extra zero there, buddy. It's 4500mAh, an interesting find nonetheless :)

Too risky to put a non-genuine battery on such an expensive phone though.

---------- Post added at 04:35 PM ---------- Previous post was at 04:26 PM ----------

So you're saying that you have your phone as a digital photo viewer, a total of 14 hours of Screen On Time.... and you want to test your battery... for what purpose exactly? I may have misunderstood your post. Could have posted your Battery Usage and History for everyone's indulgent.

People with 3 hours of Screen On Time around here will kill you for your SOT ;)
[Galaxy Note 4 General] EP2008:
Same size as the standard battery, but I'm willing to bet that it actually has 75% of the original battery's capacity. These cheap 3rd party batteries generally suck big time. LOL :D
[Galaxy Note 4 General] podface:
I wonder if its a typo and he meant 4 :p
[Galaxy Note 4 General] ilegales:
here is my battery

as i mentioned i am using my phone with some light internet. snote /

mainly having the phone sit next to me when i am retouching on my tabletop

the phone screen is constantly on and using it as a photo viewer..

screen brightness is about 30%

snapdragon version

but i am not sure if this screen time counts as i am not exactly hammering the phone with wifi / gps etc

so that is why i wondered if there was some standard test programme to see what and how our batteries perform
[Galaxy Note 4 General] ShadowFlare:
Can you also tap the graph on the first screenshot, it will bring up the Battery History, then can you post a screenshot of it too if possible.

Screen On Time is literally the amount of time you have your Screen lit up. The only time people use the software to test battery is the ones they use in reviews, for example Anandtech uses Basemark OS II. But generally people here just quote their own usage, based on how they use their phones daily.
[Galaxy Note 4 General] sampglov:
Hi everyone. Just a bit of (hopefully useful) advice that I found has worked. If you goto your application manager and check what apps are running when you are not using them and potentially delete the ones that are running in the background (ONLY APPS, not system processes)

It may seem obvious, but I had 6 apps I never used sapping precious battery life when not in use and deleted them. I've now gone from losing 50% of my battery in 12hrs (10.5 of these with the Note 4 idle and not in use) to only using 25% of my battery with the same usage.

I'm very happy now with my battery life
[Galaxy Note 4 General] ilegales:
note 4 is now charging so i took a snapshot with my other phone...
[Galaxy Note 4 General] Azcaron:
This clearly tells nothing.
[Galaxy Note 4 General] ShadowFlare:
Thanks.

Well you beat Anand's SOT battery test, but maybe because the calibration of 200 nits mentioned on their Article leads to higher brightness setting than your 30% brightness.

[IMG="Anand Battery"]http://images.anandtech.com/graphs/graph8613/68398.png[/IMG]
[Galaxy Note 4 General] EP2008:
Seriously, how the hell are they getting over 11 hours of SOT? This is 200 nits on the lowest screen brightness (a.k.a. nighttime reading mode)?
[Galaxy Note 4 General] alex989898:
No, that's 2nits.

At 50% brightness, the Note 4 use around 290nits so I assume that 200nits must be 30-40% brightness (but that's not linear).
[Galaxy Note 4 General] EP2008:
Here's what I got benchmarking at 50% brightness : http://xdaforums.com/showthread.php?t=2923152

I doubt the extra 90 nits adds hours to the battery. Heck I'd be singing from the rooftops if I could get 9 hours of browsing , let alone 11!

[Galaxy Note 4 General] alex989898:
You can't compare results like that. The testing methodology of Anandtech is unclear (we don't know what protocol of connection they used, which operators, exact strength of the signal, settings or even which sites or content they used and what is the refresh rate).

Displaying dark content with a very low refresh rate will result to far better battery life than displaying a full white page very second with poor signal lol.
[Galaxy Note 4 General] EP2008:
But 11+ hours? Double the average we all seem to be getting? I try to use black themes with every app, but don't get close to those numbers.

Sent from my SM-N910U
[Galaxy Note 4 General] ilegales:
yes is why i asked if there was some standard test like to loop a video at max brightness and see how long it runs for

i got 14 hours of OST....

but used it mostly as photo picture viewer...
[Galaxy Note 4 General] alex989898:
To be fair, Anandtech results are very strange since ages. They got better battery life with a Nexus 5 than with a GS4 and a Note 3 is only 17% better in the best case.

An iPhone 6 (not +) got very good battery life where almost all sites complain about it.

So yes, Anandtech results must be taken with a grain of salt.

But, I think it's possible to get more than 10h of screen time with the Note 4, even with high brighness.

At the maximum brightness, the Note 4 screen doesn't consume a lot more than the 4" screen (not even HD) of the iPhone 5S on Average Picture Level.
[Galaxy Note 4 General] ShadowFlare:
Go back to the previous page, I was commenting on [MENTION=4677146]ilegales[/MENTION] more impressive 14-hour SOT lol.

I get about 6 hours screen on time only any tips on how to increase my battery time???
[Galaxy Note 4 General] badbadtz.carlo:
i get 4.5 -5 on my 910c... so any tips would be nice and much appreciated..
[Galaxy Note 4 General] Hendrickson:
So a snapdragon 805 model got almost 14 hours SOT? More towards the trend that our Exynos soc is not as battery efficient as we would like to have thought. I did my own little test, I disabled fast charge in the options as and my battery life is MUCH better. Seems quick charge = quick discharge?

Or there is something wrong with the 910U roms giving us crappy battery life over other models? Or the modem is too aggressive keeping signal and burning the battery up faster?
[Galaxy Note 4 General] ShadowFlare:
I say it's the modem being programmed to be very aggressive in maintaining signal. In the Underground Tube where there is no signal, my Note 3 and S5 mini would get warm and burn so much power to obtain signal. After 30 minute journey, I'd lost ~5% battery.
[Galaxy Note 4 General] NoteMaxx:
Before I started playing games, I remember being able to get up to 8hr SOT on my 910C.

I do not have 4G connection in my area so that probably helped.

Brightness : Auto (tried manually setting lower but GSam reported higher ma than on auto)

Tweaked S-pen alerts , disable pen detect when pen is inserted.

Dark wallpaper, Wifi manually turn off when not in use, no power savings(Gsam reported around 40+ mah extra when Wifi's idling)

Removed my Samsung account, it's crazy just how much permission Samsung's apps ask for.

Stock ROM, no anti-virus type app, no greenify either.

I'm currently playing a game named Evolution, SOT around 4 to 5 hrs.
[Galaxy Note 4 General] Dan1909:
So I've been getting some pretty abysmal battery life so far. Running out of ideas of what to do!

I've done a full factory reset, which made no difference. And the screenshots above were taken with location services completely disabled! Any suggestions?

There's quite a lot of wakelock time from Android OS and Android System, but would that really be enough to cause this much drain? Then there's the problem of actually finding a way to stop it. It's just annoying as otherwise this is a fantastic phone, and I really want to like it, but this is just putting me off.
[Galaxy Note 4 General] ShadowFlare:
Tap the graph on the second picture to show the Battery History, it's important as it shows phone signal, wake, screen history. Post a screenshot of that.
[Galaxy Note 4 General] Dan1909:
Unfortunately those were screenshots that I took last night, and I didn't get one of the battery history page. However the phone is behaving much the same way, so I've attached one that I have just taken; hopefully it's of some use!

The mobile signal is poor where I am at work, but not terrible. It's much better at home (the green bit at the start of the graph), but the battery drain continues even there! And the large section of awake time towards the start of the day was streaming music on my walk to work, the rest is just random wakelocks.
[Galaxy Note 4 General] ShadowFlare:
I wonder if you have Samsung account logged in. Previously someone posted an app called Samsung Galaxy kept waking up the phone.

Do you also have WiFi scanning switched on? And any weather app loaded? Bad signal play a big role on Android System high usage.
[Galaxy Note 4 General] Dan1909:
I did have my Samsung account logged in, but I've just removed it to see if that helps.

Do you mean the "always scanning" setting? If so, then that it switched off. For weather I only have Beautiful Widgets set up on my home screen.
[Galaxy Note 4 General] ShadowFlare:
Ok, it's possible the Beautiful Widgets app contribute to wakelocks too. I have this app too and I have gone into the Settings > Battery / Bandwidth, then under Battery Savers I checked everything except "Don't use GPS". This way it doesn't check for weather (and wakelock your phone) unless the screen is On, even if I set it to check the weather every hour.
[Galaxy Note 4 General] sampglov:
Try going into Application Manager and see what apps are running when you are not using them. Any apps that you dont use, either disable or delete them. I did this and now I get double the standby battery life I was getting before.
[Galaxy Note 4 General] Dan1909:
Right, uninstalled Beautiful Widgets just to be sure.

Thanks, will go through and see what I can get rid of.
[Galaxy Note 4 General] tmac31:
go in developer options >process stats and you can see what is running
[Galaxy Note 4 General] Dan1909:
Thanks, will take a look and see what I can get rid of.
[Galaxy Note 4 General] michsu:
look at what (and how many) processes run.. I'm able to keep everything on (all networks, bluetooth, sync) and got the processes down to 30-40 without affecting anything.. I use a combination of DU Battery and Task Killer Pro (I use the 'off screen kill all at Crazy Mode'.. I know it just turns it off services and they will restart later I turn on my phone).. I managed to get 45 minutes on screen time and the battery drops to only 90%.. I'll post a screenshot on SOT when I drop back down to 90%.. running a display timeout at 10 minutes to test it.. I also use Floatify on the lockscreen too.. these are the three services that I keep on.. the others are frozen by DU Battery (I tried greenify, it didn't work too well because hibernate turns the notifications off.. I still want email and other notifications on the lockscreen)..
[Galaxy Note 4 General] michsu:
Screen shot at 91%... some in videos like in and crunchy roll and Google play updates and news like cnn and la times.. also some milk music playing too as in the 2nd screenshot..
[Galaxy Note 4 General] kinghu:
My 9100 (dual sim / 3,000mAh / Snapdragon). Not rooted or any 'saver' apps. Purposely run down faster than usual to test the battery.

One SIM China Mobile, the other China Unicom. Usually decent signal for both.

Mostly on 4G with some H+ doing a mix of internet, email, tapatalk, calls and a movie.

Typically I always get 6-8 hours. Not sure how I'd keep it if I only got 3 or 4 hours. Seems like the Exynos is thirsty.

[Galaxy Note 4 General] Lodix:
I thought this thread was about Galaxy Note 4 :P
[Galaxy Note 4 General] aooga:
It's the same thing. Snapdragon processors are very good with battery life. They've been consistently better than the exynos ones, but hey I could be proven wrong.
[Galaxy Note 4 General] Lodix:
No, it isn't. First of all the Exynos in Galaxy s4 was bugged and could only work in Cluster Migration which is the worst situation for the big.LITTLE cause it drains the battery the most. The new exynos is not based on the old Cortex A15/A7 and It is built on 20nm. There is a HUGE difference.

And while the Exynos S4 had worse battery than the Snapdragon, it was more powerfull.
[Galaxy Note 4 General] aooga:
Lol no it wasn't. In benchmarks yes, but it lagged much more than the snapdragon one. As I said, I could be wrong, but based on every other phone with the exynos processor, I'm pretty sure the 805 will get better battery life. Not to mention far better development support. Samsung doesn't even release the source for exynos.
[Galaxy Note 4 General] Lodix:
Did you have one ? I always read that it performed very well from people that had one ( just take in mind Cortex A15 >> Krait 300 ).

The developer support is just of being the international version.
[Galaxy Note 4 General] aooga:
No, but I did watch some YouTube videos. :)

The s4 was a generally laggy phone though.
[Galaxy Note 4 General] CLARiiON:
Qualcomm will use the same tech that Samsung used in 5433 in their next-gen SOCs. They will also use same A5x series IP for 808/810 etc., In reality Samsung have a upper hand in this design as they clearly have a head-start. By next year it's already speculated that Apple will move to Samsung as they are going to 14nm fabrication, so I am sure next Exynos 7 series will also be based on 14nm. This 20nm is supposed to be a short node. Qualcomm may had better batterylife in past, I don't think it's going to continue very long.
[Galaxy Note 4 General] SAVVAS.:
I agree with this reasoning, so does that mean that the next Samsung flagships will have solely Exynos? In this octa core field,Samsung has learned many things and has already 2 years of experience compared to Qualcomm so logically Exynos has nothing to be afraid of and on the contrary has the upper hand!
[Galaxy Note 4 General] Lodix:
Maybe the international version is going to be the Exynos again but not in USA.
[Galaxy Note 4 General] dilgit:
The international version is the SM-N910F and it's based on the Snapdragon 805. Will be sold in Europe, Middle East

and more parts of the world. This is the unlocked/simfree/contact free version of the Note 4 that will recieve most

of the customed roms, right here on XDA forums...

The iSheep are a great bunch.. I bought the phone for $1250 AUS and people are calling me up offering $1450 AUS hahahahaha..

Anyway to recap.. the iPhone 6 plus battery is around the same as what I was getting with the Note 3.. So I suspect getting a little lower with the Note 4 because of the extra pixels.
[Galaxy Note 4 General] bala_gamer:
20nm exynos 5433 should have better battery life than sd805 theoretically.. curios to see an apple to apple battery comparison
[Galaxy Note 4 General] naruto.ninjakid:
I'm wondering about this. So Samsung doesn't release sources for any of their devices. If they don't and they exclusively switch to their processors in the future does that mean development will completely drop of for their devices in the future? I like Samsung devices but I still need some modifications that only rooting and custom ROMs can provide.

Even though I hear how much better Exynos processors are I always go with the Snapdragon version if given the chance as day to day performance is always better for me and especially when development is concerned.

What do you guys think? Or will it be like the note 2 where there is alot of development since there is only 1 device?
[Galaxy Note 4 General] Lodix:
You have alredy answered to your own question.
[Galaxy Note 4 General] CLARiiON:
Samsung will reduce the dependency on Qualcomm from next year. Expect more Exynos based devices. Exynos 7420 is already in works, and mostly likely on 14nm fabrication for S6.

Samsung used Qualcomm's Gobi and Intel's XMM modems in past, now they are using their own Exynos 303 LTE modem and can support Cat.6 LTE. They are also expected to use some custom core SOC after Exynos 7, and they are hiring a lot for new GPU design of their own. So, in next 2 years I would assume they would reduce dependence on Qualcomm and other vendors for most of the tech will be in-house.
[Galaxy Note 4 General] Lodix:
Well S6 is too soon for 14nm.

Does anyone have the n910f variant, thinking of getting it but if it has 4hr battery no thanks. Someone let me know
[Galaxy Note 4 General] ShadowFlare:
Your history details is not indicating numerous wakelocks, and the battery slope is steady. I think it's just due to bad signal. Try 3G for a day to see if that makes any difference.
[Galaxy Note 4 General] gtizon:
Looking at the usage my screen was never on but indicated that the device was awake numerous times. Yes I will try 3G but i dont think signal was main cause for waking device.
[Galaxy Note 4 General] ShadowFlare:
I can see the wake times on the graph, but I can't see it contributing much to the battery drain. Possibly you have a weather app, or some other app that request data through the internet., it can be anything. But since you are only saying poor battery life, asking what's keeping it awake, and 2 screenshots, of course anyone can only give general answers.

Be more detailed of what apps you have, what have you done to try minimise battery drain, etc.
[Galaxy Note 4 General] markyboy81:
Android os/system is accounting for most of the battery usage on mine, but I'm still getting 5 hours SOT and less than 1% per hour drain in standby, so I'm quite happy.

I then disabled NFC/location reporting, enabled CPU power saving, then disabled some apps using wakelock detector/greenify, and got this:

http://i.imgur.com/AvSjYXV.png

http://i.imgur.com/n52FAus.png

This includes about 3hr 30m of listening to spotify (offline) while the screen was off. Not quite as good as some of the figures reported here but a definite improvement. May try to start enabling some of the features again to see which one is the major battery drain.

Install wakelock detector. It can still work with non-rooted kitkat devices, just a bit more of a hassle to get it running. The guide should be on the app page.

Was in the same dilemma, but after having to manage with no SD card on the Nexus 4 (even 64GB may not be enough further down the line for me with large apps/4k video) and no replaceable battery, the Note 4 seemed a lot more appealing. The great camera, fingerprint scanner (which works 90% of the time) and S pen just sealed the deal. I actually prefer touchwiz, there are a lot of useless features which I can just disable but some of the features are excellent, like the one-handed mode making the major negative which comes with phablets largely irrelevant.

My first day on my note 4 android os and system high though and on wavelock detector it says total wake is 5hrs and screen on time over 3hrs dont add up :(
[Galaxy Note 4 General] kinghu:
I've a feeling our battery reports are going to become even more personalised given the raft of people going for smart watches, fitness bands and health tracking apps.

I'm now set up with a Garmin Vivosmart so Bluetooth is always on and notifications are pushed constantly, as well as ad hoc background syncing with the Garmin app.

Although we're using low powered Bluetooth it'll still have an impact so SOT as a sole rule of thumb will be less revealing.

Isn't the 5hrs wake from CPU wakelocks rather then just the screen?

That is, your screen has been off but apps have been doing something (receiving email, polling for updates, etc) without needing to light up the display.
