I'm worried that this may be another step backwards in battery life. Was annoyed a bit by my Note 3 doing worse than my 2 already...not sure I can stomach it going down more, 9991343212312.2323 pixels more than before and all...curious to see more results!

[Galaxy Note 4 General] tmac31:
Cuz If they dont do weird things they barely affect battery even apps opened by user doesnt really affect alot on background. But there is a mobile data bug on lollipop(not only on note 4 lollipop i think bug is there if you dont use 5.1) which makes like apps keep activity on mobile data even they are closed maybe thats why you see a difference with apps like that they could be preventing the bug to happen
[Galaxy Note 4 General] Kernel ranger:
I here you but it is sad that it's not just with Lollipop, like every other ROM around, someone will report better user experience after installing an app killer. While you think about that take a look at this thread:- http://forums.androidcentral.com/go...51557-why-do-i-need-google-play-services.html

I was engrossed by user's reporting back their actual experience on that particular service. It's interesting the way the thread plays out to the end.
[Galaxy Note 4 General] tmac31:
dunno about google play services i didnt delete or disable it but its not even on my battery usage. just disabled google activity and location tracker and its no longer in my battery stats.
[Galaxy Note 4 General] gekkehenkie11:
No they were not. Like said I can have my screen on for almost 12 hours at maximum brightness, exactly like the Samsung data predicts. So they were wrong. If you don't believe me just try it yourself
[Galaxy Note 4 General] tmac31:
If you checked that you can see full white screen uses almost 2x power compared to others so you have to test it with white. And you should try it with full battery cuz im pretty sure battery dies faster under 30% for me.

And how can samsung have data about it since the display power changes with apl?

And quote from anandtech "The S6 was dismantled and the other Galaxy phones have access to their power input via removable battery, so all numbers in this article are measured externally with instruments."

I doubt they can be wrong about this since 2 very different websites almost found same value.
[Galaxy Note 4 General] autosis:
I don't have a screenshot to hand, but I've had great success disabling all the bloatware (Superlock package disabler) and switching from Facebook to Tinfoil (on my AT&T Note 4). Battery drains at about 1-2% per hour if I leave it alone. SoT is about average. I also disabled Google Now (as it's not that helpful to me) and OK Google detection when the screen is off (don't use it). It's the best that I can get without rooting. Clearing cache (and clearing app cache) helped too.
[Galaxy Note 4 General] gekkehenkie11:
I do agree it's a bit weird, especially Anandtech is usually quite good. Only one way to find out :) So, I'm going to re-run the test, totally white screen this time, brightness at max, CPU locked at 300 mhz, all hardware features disabled, airplane mode, display time-out set to 30 minutes. Only factor is that the battery is almost full, so will try sometime later when the battery is below 30% too. Anyway for now, going to run it for 2 hours and see how much it drains. BTW, samsung supplied 2 values as you could see, screen and screen full, I assume that display max was full white.
[Galaxy Note 4 General] gekkehenkie11:
Ok, battery drained 22% in exactly 2 hours, so that would be over 9 hours SoT. Will try also with battery below 30%. But it still seems much better than Anandtech's numbers ...

---------- Post added at 04:54 PM ---------- Previous post was at 04:48 PM ----------

I'm not sure I understand that part. What are they saying ? I get from this statement that they did not measure solely the display but the power the whole phone drained, by simpling checking the power the battery supplied to the phone ? That might explain it.

*EDIT 2* Another factor that might explain it, is that I ran the test without HBM. Switching HBM on makes the white quite a bit whiter, so will have HBM on when I do the test below 30% battery
[Galaxy Note 4 General] tmac31:
they dismantled the phone and measured only screen i think but [MENTION=4167023]AndreiLux[/MENTION] could explain better i guess
[Galaxy Note 4 General] AndreiLux:
I see you're as always quick to claim others are wrong and you right.

I hooked up an external power supply instead of the batteries and have another expensive thing to measure power with.

Also what you guys are discussing and testing by running the phone screen-on is average power. Average power will always be higher than the minimum linear luminance power that I published because the CPU and components will still be doing stuff in the background.

Edit: Why are you guys even discussing this now, the Note 4 numbers were published in February: http://www.anandtech.com/show/8718/the-samsung-galaxy-note-4-exynos-review/10

Edit: Thread cleaned a little.
[Galaxy Note 4 General] gekkehenkie11:
So, did another test, 24% battery drainage in exactly 2 hours, from 33% to 9%. Again with maximum brightness. Slightly higher than my previous test (22%) but I think that was because the first test was including a black status bar, now it was 100% white screen, that probably explains why it was 2% more this time. Both tests were done in movie mode, pure white screen (255,255,255) and of course maximum brightness

So that would be 8 hours and 20 minutes to drain the battery or 386 ma/hour. Given that 300 mhz CPU eats 34 ma, the screen at full brightness seems to take about 360 ma/hour. Or in watts, the screen at maximum brightness is <= 1.37 Wh.

Are you talking about regular use or the test like I performed (CPU maxed at 300 mhz, all hardware features disabled and phone in flight mode).
[Galaxy Note 4 General] BlackCrow-It:
Regular use. With Kitkat I got 5h and 40m with 15% left. Mostly wifi, youtube, music, what'sapp, facebook, and other little stuff. But I had a low brightness most of the time. I'd say like [MENTION=2252917]VuBoo[/MENTION]

So basically is it possible to get 6h sot at 15% with medium brightness?
[Galaxy Note 4 General] gekkehenkie11:
ah no the test I did was just to find out how much the display consumes at maximum brightness. Normal SoT highly depends on what you do during SoT but should be somewhere in the 3-7 hours range with 4-5 hours probably being normal, but again, highly dependent on what you do
[Galaxy Note 4 General] BlackCrow-It:
I'm just asking this because when I bought it I got 7h Sot and after 5/10 days I started to get 3-4h sot!

I have downgraded to 4.4.4 a week ago. This gave an improvement, but still no talks about 2 days without charging (I am away from the idea to turn off sync and other stuff, otherwise why buy this kind of phone).

But once turned on, the phone dowloaded a lolipoop update and started to remind me constantly to install the upgrade. One cannot easy get rid of those reminders, they popup all the time. And finally yesterday I suddenly pressed Install after unblocking the phone. :mad: I wish someone in charge of software in samsung would get a nail in the head.

[Galaxy Note 4 General] lelik11a:
Something strange here. If I have wifi on, I get 5-6% per hour. But if I turn wifi off, I get 2-3% per hour. Usage pattern is the same. I thought it should be the other way around.
[Galaxy Note 4 General] hellsbell:
you can check in setting, apps and desactivate software update (in some roms, it is possible to do it)

Having said that, lollilop 5.0.1 offers better autonomy and overall experience as far as i am concerned

---------- Post added 2nd July 2015 at 12:04 AM ---------- Previous post was 1st July 2015 at 11:50 PM ----------

If the wifi signal is weak, it can cause battery draining. There is the option "switch between wifi and 3G..." If enabled, it guess it may increase battery use.

with wifi on, sync on, localisation on (battery saving mode), i get 1¨% per hour.

Overall, with mixed use, but without playing games, the battery lasts 25 hours. Wifi, sync and localisation (battery saving mode) always on. The cpu temp is around 40 celcius, and if surfing or dowloading from the store, the temp can briefly rise to 80 degré celcius (185 F) before going cooler quickly (down to 50's). The battery temp is around 30-35 degré celcius (86-95 F) .

Is this normal ?

ps : i precise my phone is still new. I read somewhere it needed some start up period for the battery to be more efficient
[Galaxy Note 4 General] hellsbell:
Thanks for your contribution !

I have a note 4 since some days and i noticed internet browsing while on wifi is very aggressive on battery and cpu load/temp. My wifi is always activated as most of the place i go have wifi.

it has often been reported that wifi is less consumming than mobile data, that's why i am a bit surprised. I'll give it a try. After all, Wifi is less important nowadays and could only be activated for specific tasks.

I can say i have less heating and gained some autonomy since I replaced the gmail app (that constantly use push mail) by the native mail client.

In the email app, i set synchro to (every 30 min) and disable push mail. I really don't know if there is some other factors but my autonomy clearly improved. I think it's worth trying.

Apps like facebook may drain battery too. i don't know how it works but it could be similar to push mail

Has someone found a way to manage sync frequency of facebook ?

Is there a bige difference in battery life on KK and LL ? When i switched my note 3 for note 4 i flashed LL right away.

Can someone provide a good battry life screenshot on KK?

I know that i had on my note 3 (on KK) about 6h SOT with 48h-52h of usage. But on my note 4 i cant get 2 days of usage no matter what. I can get about 5-6h SOT, but right away after charging and in about 18h of overall usage. The sleep time just sucks on LL.
[Galaxy Note 4 General] LifeDrainerRO:
I had KK on my Note 4 but a friend installed Lollipop by mistake so now i am using it. I'd say the battery life is better on KK but not by a huge margin, around 30-45 min SoT on average. Standby time is good on 5.0 but i think the battery drains quicker with mobile data on. I have attached some screenshots with KK. I had 1d and 5h with 93% left, was some kind of experiment. At the end had 2d and 18h with almost 4h30m SoT. I am generally an average user, with periods of either light or heavy usage

Hi i upgrade from s5 to mote 4 yesterday and the first battery charge i dont notice different from s5. Does the battery stays better after 2 or 3 charges. ?

Oh i have data all day on.

Sent from my SM-N910F
[Galaxy Note 4 General] LifeDrainerRO:
If it's new, the battery needs 2-3 cycles to reach peak performance. I've upgraded from S4 and the battery on the Note 4 is ~ double. My S4 was 14 months old so the battery wasn't new anymore though. If you have more than 2 hours screen time in that screenshot its not a bad performance with mobile data on all the time. Depends how do you have your phone set up (sync, etc). Today i had ~30 hours on battery charge with 6h screen time on Lollipop but i mostly used Wi-Fi rather than mobile data, average use.
[Galaxy Note 4 General] cavags5:
I have like in s5 all the apps i dont need i disable, even GPS i turn off sometimes i have all options all controlled. But have data all day on like i had in s5 all days turn on.

Lets see how it works after 3 4 charges. But i was hoping that last at least 1day and half with note4.

How long it will last s6 battery. ?

With 2550 battery
[Galaxy Note 4 General] LifeDrainerRO:
The battery life on S6 is pretty good, not the same as on Note 4 but quite decent. I'd say about 70% of what Note 4 can achieve. I have a friend with S6 and its ok.

On previous post i meant the battery life on the Nore 4 is almost twice as good compared to my 14 months old S4, not the actual battery capacity.
[Galaxy Note 4 General] cavags5:
Today is the 2 charge.

And im feeling the battery last the same has s5. Let's see one more week how it goes.

I thought a little bit in buy the s6 , but the sd card i like very much.

In note 4 i thought the battery was much better, but the bigger screen and s.pen are top.

Only notice a little bit in the pocket.

I'm in time to change for the s6.
