First loadcycle with my Note 4. Only edge and WLAN. no 3g. Auto brightness +5 location and bt off. Just Web browsing and whatsapp. No gaming or movies. I debloated some apps. I dont use Facebook or something like that. OS is Still kitkat. I am afraid of updating to lollipop because of worser battery life. This is all i need. Just awesome if i compare to my old LG G3..

Edit: i use the european Version with snapdragon

This is my note 4s battery on Alexandrs rom, literally as I wrote this the battery dropped from 15 to 10 percent in 2 seconds, it'll probably die soon. Basically I took it off charge around 12 I just used the Web and whatsapp all day no location rarely, just WiFi no 4g, I turned power saving on at about 40 percent battery and this is the only battery I get I have greenify installed, use Google now, nova launcher I really cannot work out why my battery is so absolutely awful

I got roughly 3 and a half hours screen on time today and that was with power saving too, clearly something is wrong but I can't work out what
[Galaxy Note 4 General] Veereihen6:
I've recently been seeing some really bizarre behavior from my battery. On 2 separate occoasions in the past few days, the battery has gone from over 60% to dead instantaneously. The first time it happened, the phone had just started updating a couple of apps over wifi, and all of a sudden i get the low battery shutdown msg. The second time happened today, and the battery was over 80%. I was trying out Google Cardboard, and once again, the msg pops on screen and phone goes dead.

My phone is a Sprint version Note 4 with the BOB7 firmware, rooted. Is this a sign of a defective battery, bad phone, or Samsung firmware?
[Galaxy Note 4 General] cavags5:
Now i see how removable battery is always better. Since i starting charging without fast charging battery last longer.

This morning i left charger 8h am take my breakfast with Wi-Fi maybe 15 minutes,stays 97% went to work i turn off phone remove the battery and put it again turn on 100% and stays more 1h standby like in photo.

Nice.

Whyyyyyyy ???
[Galaxy Note 4 General] spexwood:
It would be mobile signal, not mobile data. Drain from a bad signal would happen whether using wifi or data. The only way to eliminate the signal as a possible cause would be to keep your phone on airplane mode. You can try keeping your phone in airplane mode for a while to see if there's any improvement, but I don't think it will help dramatically in your case.

Even the crappiest mobile signal shouldn't make your phone drop from 80%/60% to dead instantly. Over a couple hours, sure. But not instant KO.

I think your battery is bad.

Does the phone always die between 60 and 80%? Or does it ever act normal?

Just curious.
[Galaxy Note 4 General] Veereihen6:
No, its not always between 60-80%. If I recall correctly, its happened at sub-40% as well. These were just the most recent occurrences and also the only times I remembered to take a screen shot.

It's been happening more frequently, but for the most part, it does act normal. I just worry that I'm going to have to buy a replacement battery if this turns out to be a bad one.
[Galaxy Note 4 General] spexwood:
I really do think it's your battery though.

You can rule it out by first running your phone for a day in Airplane mode (if you can). If no problems, then it most likely IS your signal.

Look at your apps too to see if something could be crashing your phone somehow.

You can also try a factory reset if not done yet. Another option would be to reflash via Odin.

These would hopefully rule out software issues. Oh and don't install apps right away.

Those are optional debugs you could try, but a new battery may be the best solution.

I wonder why you guys have Android system running on? I have no idea why I do not have Android OS consuming my battery. I'm on Kitkat ANK3 eith Ktoonz kernel. I don't think my kernel helps with saving my battery. I play PSP games most of the time so my display consumes a lot of battery.
[Galaxy Note 4 General] kuladiamond:
Hi guys, thinking of switching to a phablet. Sensing that the Note 4 might suit my needs as I'm looking for a device that can act as a tablet when I'm home. Wondering how the battery life is gonna be if I do a lot of YouTube and web browsing. Would it last the whole day? How's lollipop treating the note 4 in terms of battery life? I currently have a nexus 4 and nexus 7. Could the note 4 replace them both?
[Galaxy Note 4 General] ssuper2k:
Hi all,

I switched a couple of months ago from a note2 to note4, and I'm feeling the n4 battery lasts half his little brother did.

I even downgraded to kk4.4 but still the same. Hardly lasts the whole day.

Has Samsung made it so bad?

I also wish they had kept at 1080 for phones

Browsing web sites with large images and text at the same time is a mess case of the zooming fonts.

Can anyone recommend be a good rom for the battery?

Thanks
[Galaxy Note 4 General] cavags5:
I charge my note 4 without fast charging and when its 95% i remove battery put it again and yes 100% again. , someone could try it and let me know if does the same.

Hey mate. Have you tried the FireKat rom? As far as you're owner of a snapdragon (4 cores).

http://xdaforums.com/note-4-tmobile/development/firekatn4v1-4-4-4-tw-anj7-extremely-t2916463

The rom has been created for T-mobile Notes, but there is a version for international's. I'm a happy user of a N910F, which is snapdragon. People used to achieve this way unbelievable stats (such as 10+ hrs sot).

If you all can't get a proper sot and your phone doesn't last a day, I'll post down there some useful setup.

First and the most important - install FireKat. Belive me, I went through every Lollipop and Kitkat rom. I have downgraded from Lollipop to KitKat a few months ago and it was the best thing I could did that time. One rom, beside FireKat, gives nice battery life, but it's discontinued.

Second - Follow the tips provided in Op2.

http://xdaforums.com/showpost.php?p=56241554&postcount=2

Third - for extra juice, gives perfect standby time.

So, battery discussion developed in another thread. Basically user [MENTION=349237]bronx[/MENTION] is claming that he can get 10 hours SoT with web browsing, with unmodified CPU speeds:

Of course this is highly impossible. But just for the fun of it, let's discuss it here. Post you ADB batterystats log so we have actually something to talk about:

adb shell dumpsys batterystats > out.txt

If you dont have adb installed, here's how to do it: http://xdaforums.com/showpost.php?p=62182146&postcount=43

OK pal, I shall post my results on Saturday, as it is my day off, so I shall be able to afford wasting time for this test. In the meantime there's a question for you. Are you calling me a liar?

[Galaxy Note 4 General] gekkehenkie11:
10 hours web browsing without limiting the CPU is just impossible. The screen will take about 100 ma already at the LOWEST brightness. So that's 1000 ma for 10 hours. Although, it's probably too conservative because web browsers usually have white screens, so that would take a lot more battery. But let's go with the low estimate, 1000 ma for 10 hours of lowest brightness screen. Then the CPU speed. Web browsing is highly CPU intensive, it has has to render an UHD screen and processing web pages in general is CPU intensive. Highest CPU speed would take almost 400 ma/hour. But let's say you're averaging 200 ma/hour, seems usual for browsing. So that's 3000 ma already. And if you're web browsing for 10 hours, then let's say your WIFI is actively doing things for 2 hours. So that's another 900 ma. So that's 3900 ma already and we haven't even included wifi scanning, radio (and scanning), disk access, sensors, audio, things like that. And you're way over the 3200 ma that our battery has already, I think you'd need a 5000 ma battery for that.

So yeah, pick one of the above. 10 hours of web browsing without limiting CPU speed or changing the CPU governor, it's just impossible. Even 8 hours is impossible. And somehow the people who claim to get those magical results are beginners running unrooted touchwiz and who dont even know how to make an ADB batterystats dumpsys to prove their point. Saturday, why saturday ? Can't find the 2 minutes right now to do it ?

I mean, come on, you accused me of not being able to do math and come here with some ridiculous claims, what kind of reaction do you expect.

My phone is now charged to 100%, at what point shall I dump stats? After an hour od use? Couple of hours? I am happy to do it whichever way you like. I proposed to do a full discharge test from 100% to ~0% to prove my point with all new screenshots, but we could run a short version tonight.

Hehe and that's pretty much what he did :) He had his phone on for 3 hours. These are his screen brightness stats:

LOL. Next he put up Chrome for the 3 hours but only used it half an hour, see his chrome stats:

(try it yourself, you will see that if you do normal web browsing, even without touching the screen constantly, your foreground activity will equal the foreground time. Touch it 6x per minute for example and you will see: foreground activity = foreground time)

So this joker just did 30 minutes of web browsing and then just left the browser screen open for 2.5 hours at the lowest possible brightness.

Man, can I get my time back that I put into looking this log please :mad:

This is nonsense. My brightness was set to 'auto' all the time, also what is your problem with usage of chrome? Rest of this time I was using WhatsApp and apps for browsing Reddit and Wykop. As I was stating from the beginning - this is best case scenario - using phone constantly, without any modifications, auto brightness with adaptive screen, good WiFi signal. The device was idle (i.e. screen on w/o me touching anything) for no more than 60s at a time at most. You said, that this sort of s.o.t. is not possible at all.

Busted? His definition of web browsing is constant loading of new content and touching screen all the time without reading. Looking at what you are saying, you find reading hard too.

By the way, I have installed over 110 apps according to play store.

[Galaxy Note 4 General] POLO_i780:
Exactly!

Also one must take into consideration things like usage habits, network quality etc... Back in 2010 I had a Xperia X10, its battery life was average due to unstable 3G in my area, it would go between HSDPA, EDGE and GPRS constantly, then my network finally put up another mast and upgraded the existing masts, my battery life shot up as the signal was now stable.
[Galaxy Note 4 General] gekkehenkie11:
Well your battery stats say your screen was 'dark' for 2 hours and 'dim' for 1 hour. I dont care if you did that manually or via auto brightness in a dark room.

You said you could get 10 hours of web browsing. Now it turns out you only did 30 minutes of web browsing. That's of course the key here. Install an app called 'TREPN' and use it as CPU overlay, then you will see how CPU intensive web browsing like chrome is. And that, my polish friend, is the reason why you will never get more than 6 hours web browsing, unless you limit your cpu frequencies.

Nonsense. 6x touching your screen per minute (!), that's very very far from constantly touching the screen. If you dont touch your screen at all, I can get probably 12-14 hours SoT with 'web browsing'. So what ?

People who do web browsing interact with their screen at least a few times per minute.

---------- Post added at 02:15 PM ---------- Previous post was at 02:10 PM ----------

They can be configured differently. But the power per hardware component is ALWAYS the same per device of course, that's how the hardware is designed. Like for example, if you set your screen to full brightness, put up a white screen, let it contantly access wifi, play some audio and your cpu is maxed, you will NEVER EVER get even over 3 hours screen on time ! It's simple as that.

These are ma/hour. And the battery has 3220 Mah. So if you could turn off all hardware except WIFI and would do 100% wifi usage, you could reach max 3220/487=6.6 hours !! But it's of course impossible because the CPU is always on when WIFI is on too of course so you will never reach 6.6 hours SoT with full wifi usage. Keep in mind that this table is not complete and that these are just *averages*. If your wifi connection is bad, it will even take more. Same goes for the screen, the values are not based on purely white screen (like in a web browser most of the time), that consumes a lot more (about 330 MaH) !

Conclusion is that Chrome is a nasty resource hog, also that one can spend time on web reading/watching content using other apps. Once again, like a broken record, I am not talking about hermetic benchmark scenario, just real life results. I officially stop this conversation at this point, as it is taking us nowhere.
