Yes it was enabled, it went really fast up to like 80%, phone was very hot to touch and then after that it was slow and cold.

Battery hikes suddenly become frequent

Dear fellow members, can anyone explain this kind of drops in battery percentage. They started a couple of weeks ago and are happening almost on a daily basis now. Is it related to the Marshmallow variat that i flashed cos i am considering to change it. Or is it the reason samsung is bringing the June security patch to note 4?
[Galaxy Note 4 General] Amar.B:
Try to clear the cache from the recovery
[Galaxy Note 4 General] saru789:
No recovery installed as phone is in stock condition. I only flash stock roms via odin
[Galaxy Note 4 General] Amar.B:
With stock recovery you can wipe cache partition

After almost 2 months since upgrading to Marshmallow, I got the impression that N910F has a poor battery life compared to Lollipop 5.1.1, with 2-2,5 hours SoT. Is it just me, could I have a problem with my phone (although I factory-resetted it after upgrade), or there is someone else experiencing the same thing? I repeat - on a N910F-Snapdragon, not C-Exynos (stock firmware, DPE7 version after latest OTA).
[Galaxy Note 4 General] woldranger:
It's not MM, it's either an issue with your phone or the battery needs to be replaced - I bought a used Note 4 and updated it to MM straight away so I can't compare it to LP, but with similar tweaks that I ran on my Note 3 I'm getting well over 4 hrs SOT, up to 5.5 and over a day between charges - normally a day and a half with "regular" (not that you can really quantify that!) usage. I bought an Anker replacement battery and both that and the old battery that came with the phone are getting me solid results.
[Galaxy Note 4 General] StevePritchard:
Although it's possible that there genuinely are a few settings/tips/tricks to getting better battery life out of your device, the comparison between different people's devices is a bit pointless. Factors such as battery age, installed apps, proximety/type of cell towers, screen brightness, and what features are switched on/off can all have an impact on battery life that makes direct comparison pretty meaningless.
[Galaxy Note 4 General] iopah:
Feeling the same here. I thought that it is just the battery came to its end. Bought a new jenuine one and the phone life is the same - hardly holds 12 hours
[Galaxy Note 4 General] alexeei:
See same results, LL give 1-1.5 SoT more than MM with same usage on 910F for me, but 2-2.5 it's too small, i have on MM 3.5-5 SoT with 2G/3G, autobrightness and no games.
[Galaxy Note 4 General] ithehappy:
So the battery backup of on PF2 firmware has not changed, even with heavy usage you can pull off 5 hour SoT! However the performance of stock kernel is really poor, even with DVFS disabled, with it enabled, gaming is like, better leave it.
[Galaxy Note 4 General] meso87:
Hi guys, I have a quick question for you. Isn't that Wi-Fi bar supposed to be interrupted? And does this means that Wi-Fi is always on? View attachment 3806261
[Galaxy Note 4 General] ithehappy:
It's like that because of the always scanning option being enabled. Even if you turn off WiFi that option makes the WiFi to always scan for signal or something.
[Galaxy Note 4 General] meso87:
It could be. Where can I turn off that option? Ty
[Galaxy Note 4 General] imeem:
It then Wi-Fi settings. Mines is set to do but it's still says it's on. Even when I turn off my phone, when I turn on my phone the next day, it's still says Wi-Fi is on.
[Galaxy Note 4 General] meso87:
Checked Wi-Fi settings and there is no option to turn it on or off....
[Galaxy Note 4 General] imeem:
Check the image.
[Galaxy Note 4 General] ithehappy:
It has been moved under Location settings from Marshmallow.
[Galaxy Note 4 General] meso87:
I don't have that option at all in Wi-Fi settings. Improve accuracy is turned off since I started using this phone. But now I have selected "GPS mode only" in location settings and I will see the results. Maybe it's bug ? Thank you guys anyway ?
[Galaxy Note 4 General] Evthymios:
[MENTION=5096032]meso87[/MENTION]: It's not a bug, the WiFi bar in battery status will appear interrupted if you choose in WiFi Advanced settings, under "Keep WiFi on during sleep" one of the other default options: "Only when plugged in" or "Never" (check the screenshots below).

But be aware that your actual battery usage may increase - 3G/4G is more battery-consuming than WiFi...
[Galaxy Note 4 General] meso87:
[MENTION=4594128]Evthymios[/MENTION] tried that too, it's off atm but with same results. Never mind, I can live with that flat line, just thought I can fix that. With this settings I have 3.5 to 4h of sot, considering it's over a year old battery that's great for me ? thanks anyway ?
[Galaxy Note 4 General] ithehappy:
The battery backup of stock kernel is just great in MM gotta say, but with very poor performance, well you can't have everything anyway :)
[Galaxy Note 4 General] Evthymios:
On DPE7 firmware it works as I said, maybe you can consider an upgrade to this version or a higher one (I think DPF3 it's the latest).

But, nevertheless, I noticed no improvement in battery life by turning off WiFi during sleep (rather the opposite).

From what the others say, 3,5-4 h SoT it's at the lower margin - I managed to achieve better results than the ones posted previously with Greenify non-root "Aggresive Doze" mode and latest stock firmware (and an 1.5 years battery)...

Battery percentage

Hi everyone. I noticed that when Im using my Note 4 n910C every 3 or 4 minutes the battery percentage becomes less 1%. During this time I usually use Whatsapp or I browse web with auto brightness. Isnt it too much?? I expected this happen every 10 minutes.

My best SOT was 5hrs with 11% remaining. Is the battery OK?? I bought my phone 2 weeks ago and now Im really worried about its battery. Please help
[Galaxy Note 4 General] Amar.B:
It's totally fine no need to worry. Mine is 2 month old i managed to get full day of use with 6.30hrs sot but not all of the time i am getting these results depends on too many factors. Your network signal for example if you are using 4g and your network signal is weak it will drain your battery much faster. So if you're using wifi at home/office switch your network to 2g/3g, you can disable all the stock apps manually like Google play movies..etc. yesterday i charged my phone before i go sleep to 100% switched off sync/Bluetooth/gps and left the wifi with 4G network i woke up after 8 hrs with 88% left.
[Galaxy Note 4 General] joker.1999:
I dont use 4g at all. I use wifi during web browsing or using online apps. Network mode is GSM only. But whenever I look at battery percentage I see that 1% is less. I calculated an average: Every 3.6 minutes 1% is gone. Ive disabled some apps. But I havent rooted it and I dont have greenify or similar apps. I saw that some people have gotten 6 to 7 hrs of SOT. But as I said my best SOT has been 5hrs. This is a little unfair:laugh:
[Galaxy Note 4 General] Amar.B:
Well my experience with this phone for the past two month not rooted stock 100% getting 6 to 7 hrs aot happened a few times but not all the time my average is 1 day of use and 4hrs sot and sometimes less than this. I don't play games at all only Tapatalk, chrome browser, Bluetooth paired with my car stereo (sound cloud) my everyday apps
[Galaxy Note 4 General] imeem:
Your usages seems better than mines. So I think yours is fine, and mines is 4 months old. What is ur SOT @ how long your phone is on for?
[Galaxy Note 4 General] joker.1999:
Here are my stats...the best record so far. Are they good?
[Galaxy Note 4 General] imeem:
That's pretty good in my opinion. Your app usages is like the same as mine. I used to get those kind of battery life on a particular 5.1.1 build, but not anymore after updates. Your SOT and overall on time is better than mines. (I get like 17-21 hours overall on time @ 4-5 hrs SOT. I'm still holding back on Marshmellow.
[Galaxy Note 4 General] zviki:
My problem was exactly the same. Last week I finally take my phone to the service, because it's still under warranty. They changed the screen because it was burned-in, they changed the battery (sudden power-offs on 50 or even 80%) and strangely - they changed some faulty system connector. Phone worked and charge before the repair. I always use only original charger, so how can be some system connector burned??? They changed it for free under warranty, so I assume that it must be some factory fault. Now the battery life is good again (more than 5h of SOT). I know few people with the same "sudden power-off" problem on different Samsung phones, so...
[Galaxy Note 4 General] ithehappy:
LOL! I found some old screenshots today of my previous phone, Note 3, and it used to give me 6+ hours SoT with Shinto kernel and the ran smooth as butter. Note 4 now is getting around 5-6 hours if I am on stock kernel, however as that's impossible for me to use moving to custom kernel makes it around 4 hours, real upgrade in battery life in Note 4 over Note 3.
[Galaxy Note 4 General] Andreas_Chronopoulos:
I noticed that even when the WiFi is off it appears at battery stats as a straight line as always on. I have turned off even the GPS assistance. That doesn't seem right

[Galaxy Note 4 General] imeem:
Tell me about it, me too. Even If u turn off your phone at partial charge, it will still say that WiFi was on when the phone is off.
[Galaxy Note 4 General] Amar.B:
Well i have to admit MM has the worst standby time even if you switched your network to 2G. This what i did

1. Cleared all the cache data

2. Switched the network to GSM only (Wifi is on)

3. Switched off Sync/location service/Bluetooth

4. No background data was running (i did restart the phone)

Left the phone phone fully charged 100% woke up with 87% after 8 hrs. Lost 13% percent a very bad standby time in my opinion. Lets hope future updates fix these issues
[Galaxy Note 4 General] imeem:
when it doubt, factory reset. Sometimes, that is the only way.
[Galaxy Note 4 General] Amar.B:
Factory reset was the first thing i done after i updated to MM. I need someone to test the standby for me so i can make sure that I'm not the only one who's getting these results
[Galaxy Note 4 General] joker.1999:
Thats completely strange!...with the same situation, my note 4 loses 1 or 2 percent during night. A factory reset may solve ur problem. If not, consider changing the battery, if it is bothering you. But my last device which was galaxy S3, had the same problem as u but this problem solved after factory reset.
[Galaxy Note 4 General] Amar.B:
It's 2 month old phone definitely it's not related battery, i had note 3 before i never faced such a problem like this literally Changing between roms every month but this one got me thinking that the last update for the G variant has some bugs
[Galaxy Note 4 General] ithehappy:
I never noticed more than 4-5% drain overnight, which generally spans to 8-10 hours. So I think you're having a problem there because some app/service is keeping your phone awake and thus draining battery. Install BBS and monitor.
[Galaxy Note 4 General] zviki:
Settings - location - improve accuracy and turn "allow wifi scanning" off.

Guys need help, I am on rooted phone and on Nameless Kernel. My phone is about 1.5 years old now. The battery life has been pathetic these days specially after MM upgrade. I am on WiFi and Data all the time, My google mail is on sync. Not into games other than whatsapp, snapchat and facebook. I tried almost everything (Greenify, Amplify etc) to stop the wakelocks. I don't see excessive wakelocks but phone has barely 2 hours of SOT. I did manage about 4~5 Hrs on LP roms with similar usage. Is it because the battery has reached the end of life? The statistics shows about 850 charge connector count(probably it also has USB connection to phone too) Any thoughts? I don't mind buying the new battery but is the battery a issue?
[Galaxy Note 4 General] Andreas_Chronopoulos:

[Galaxy Note 4 General] HRQ.SLV:
Try the stock kernel first, I was also with the Nameless kernel and the same thing was happening to me, yesterday I flashed the H-Vitamin kernel and altough I'm still testing I can see already results.

FYI: erase your IMEI from one of the screenshots.
[Galaxy Note 4 General] imeem:
Mines always been off since day 1 and it still happens. Like what I said before, when my phone is COMPLETLTY power off, the battery stats will still say that WiFi is on during the times where the phone was powered off.
[Galaxy Note 4 General] Amar.B:
Yeah it might be an app or service keeps my phone awake will test it today and report back
[Galaxy Note 4 General] tytnguy:
Thanks buddy, yes I was also thinking about it. Right now I have just reset the device and reinstalled everything fresh. Try it for a day and they I might follow you.

[Galaxy Note 4 General] limjialok:
Wow almost 7.5h sot
[Galaxy Note 4 General] joker.1999:
I changed the network mode to GSM only and power saving was on when device was not in use( over night,...).

The result is amazing
[Galaxy Note 4 General] mikkis2k:
Anyone know a rom that fits good with vitamin kernel + n910F? i see one here had 7.5H SOT with a rom called erobot.. but thats the exynos variant, right? Do we have one thats similar? :)
[Galaxy Note 4 General] MrWilsonxD:
And this was a bad day. Usually I get 5 hours SOT :laugh: :laugh:

Beast mode kernel by freeza, Anker replacement battery (same mA as stock, higher quality cells [allegedly])

I charged the phone overnight, then constantly used it for about 5 hours. Taking little breaks to walk around the house. Wi-Fi and data on full time. brightness sound 70%. No power save mode or cpu frequency altering.

And it's been hotter than the bowels of hell out here. So my phone was hot 80% of the time also.
[Galaxy Note 4 General] StarRider:
Ridiculous

I now have to have a mobile charger plugged into the phone at all times just to keep it on. If I don't, It goes from 100% to shut-off in just minutes. Maybe half an hour if I'm lucky. I've bought a 10 000 mAh charger with both 1A and 2.4A outputs, which is kinda neat.

The only positive thing is the timing with the new Note 7, which I was gonna get anyway since I always upgrade every other generation. The Note 7 will be my third Note after Note II and Note 4.

Wonder what battery times we will see on the Note 7, especially with custom ROM's and ****. ^^

Guys I currently have S5 I am getting 5hr SOT wifi use with greenify in 1 day.. I want to upgrade to note 4 .. Main concern is battery life Secondly good camera too.. Can i get 6 7 Sot with note 4 or should i go for nexus 5x...

Reply must Plz..!
[Galaxy Note 4 General] Ohhdayumm:
Seeing from other note4 users you shouldnt get it. People said the mm update destoryed their battery life/performance. But the good thing is that you could get a bigger battery. 5x wont give you more than 5 hrs. Ive only seen a few that reach 6hrs but that is with alot of modding and tweaks.
[Galaxy Note 4 General] kokbiloking:
But here many of us got 6hr + too MM is new hopefully many enhancement will be made Thus it will b good enough.. Which version has better battery exynos or snapdragon
[Galaxy Note 4 General] joker.1999:
Im now using note 4 and Im happy with its battery...without any greenify or such apps I can easily reach 5 hrs of SOT after a full charge. My usage includes searching the web using wi-fi, playing music, using whats app and.... . But about those who get +6 hrs of SOT they use some apps and most of them use other kernals and roms... if u do so u will get that time of SOT too. But I myself dont prefer those roms...good luck
[Galaxy Note 4 General] Ohhdayumm:
Oh my bad i was talking about stock unrooted. Forgot to mention that. If you plan to root i think it fixes the issues by debloating and using othe battery tweaks. I honeslty would go for note 4. The expandable memory and battery would be very useful if you plan to use the phone for a few more years
[Galaxy Note 4 General] ithehappy:
You don't need to tweak anything at all to get 5-6 hour SoT on stock ROM and stock kernel.
[Galaxy Note 4 General] sithjedi333:
Are you using mm or lp?
[Galaxy Note 4 General] kokbiloking:
Is stock N910C MM rootable.. How many apps it can hold in multitasking without root.. I am getting one for 250$ 7 8 month used!
[Galaxy Note 4 General] Ohhdayumm:
I personally dont own one but i had a friend with one and read alot about it from reddit because is was about to get a note 4 too. Btw great price for it!!!:) thats where i got all my info.

Is note 4 camera with f2.2 can beat new sammy devices like j7 a5 6 with f1.9.. I dont care about selfies main concern is low light back picture.. I am getting j7 on same prize
[Galaxy Note 4 General] ithehappy:
MM all the way. I did go back to LP after MM was released, it feels like utter crap now.
[Galaxy Note 4 General] sithjedi333:
Wow that's amazing. How did u get that kinda battery life on stock MM? Can you share a list of apps you disabled or any other settings or changes you made?

Thanks!
[Galaxy Note 4 General] joker.1999:
Btw I know its not related but do features like smart stay and other gestures drain the battery or not??
[Galaxy Note 4 General] Ohhdayumm:
That you would need to research online. Try watching reviews or if you have more time , try out the phones in store. Maybe try going to the j7,a5,a6 xda forums and reddit forums to ask the users. They will definetely give you a honest answer.
[Galaxy Note 4 General] ithehappy:
Google apps are uninstalled, Movies, Books, Newsstand and all those crap, then S Voice, Flipboard, Facebook etc. However uninstalling these apps make very little difference in battery backup. Oh by the way I rarely use data, so I use GSM/2G only mode, that makes a huge difference, I am on WiFi 24x7. And that backup with stock kernel.

[Galaxy Note 4 General] Evthymios:
I get back with news after the latest update (DPG2) on N910F - amazing battery life and SoT (better than 5.1.1, which held for me the previous record), and approx. 1% standby drain (with Greenify "Aggressive Doze" enabled, Power Saving disabled).

Finally the stock 6.0.1 seems to be working properly!
[Galaxy Note 4 General] chudiy:
I am amazed at some of the screen on times since people get, for me after the latest update, I barely get up to 4 hours, but again I have wifi on all the time, Bluetooth all the time connected to a smart watch. I make up by carrying a spare battery all the time which is why I'm not keen on the new note 7
[Galaxy Note 4 General] sithjedi333:
Thanks!
[Galaxy Note 4 General] Shari.:
When you say you get +6 hrs of SOT you mean from 100% to 0% or from 100% to 20% or...??

Because I get +5 hrs SOT from 100% to 20% and if I let it drain I will get 6 hrs.
[Galaxy Note 4 General] Kinsman-UK:
I'm regularly getting 6+ hours SoT on Marshmallow. Attached are screenshots of my battery usage at 50%. I am on stock unrooted 6.0.1 and use Greenify Agressive Doze. I have EZ Package Disabler installed and (carefully) disabled quite a bit of Samsung stuff, but all the Google and other services are still running. I have Bluetooth on all day connected to a Moto 360 Smartwatch and a Sony Bluetooth headset. I am usually connected to WiFi all day.

Interestingly, I got a new router last week and connected my Note 4 to the 5Ghz WiFi on it, but found that this drained the battery noticeably faster than using 2.4Ghz. So I've switched back to 2.4 and getting my usual 6+ hours - I am also on a new battery purchased directly from Samsung 2 months ago. Essentially I am able to use this phone exactly as I want without having to worry about running out of battery before the end of day. :good:

EDIT: N910C by the way (see signature)
[Galaxy Note 4 General] magikmichael:
I get same results on stock unrooted rom too (910F). Cant seem to get the same results on any custom rom though. Using ramrom atm but highest SOT i get with it is 4.5~5 hours, same on dr ketan rom. Tried changing kernels (xceed) but doesnt make much difference. Think it has something to do with s7/N7 edge apps etc.

Doesnt greenify slow down ur device?? Because I hate my device being slow

I dont use that app but my bluetooth is almost always off but I get the same result
[Galaxy Note 4 General] Kinsman-UK:
I can't say I have noticed any performance impact from using Greenify. I'm unrooted so can't use all the features, but I do manually hibernate and use Aggresive Doze. Avoid hibernating apps you frequently use, or any that require instant notifications, and you should be OK.
[Galaxy Note 4 General] Amar.B:
Yep i think he draining the battery till it reaches 0% to get +6 sot i usually get the same results from 100% to 20-15% with 5 to 6 hrs maximum depends on how I'm using my phone. If I'm on 4G i usually get 4 to 4.30 hrs maximum. not rooted stock rom using greenify with aggressive doze my phone is *4 month old*

I never let the battery drain below 5% mate. So from 100 to 5% for that six hour SoT mark. I even got 7 hour once, I think I posted the same in this very topic, not sure.

In any case lots of things are related. When I got those battery results I was on Vodafone, which has very strong reception where I live, almost always on Green, and network mode on 2G mostly, cause of 24x7 WiFi, but now I am using a crap network (temporarily), with LTE, and I can never get 6 hours any more, 5 hours is all I get now. Again, this is with stock kernel, if you use Nameless or Emotion you are not going to get anywhere near that backup.
