So, after setting up my phone 2 days ago i took some numbers yesterday and overnight. Standby draw is down to around 0.3% per hour (BBS shows only the first increment. I lost 2% over 7.5 hours, so closer to 0.25%). 4G, WiFi, BT and Mail Sync once per hour. Oh and an Alarm was set (if that matters).

While using the phone yesterday i lost 16% over 10 hours. SoT was around 1.5 hours (forgot to take pictures, i'll repeat that today). No heavy use currently, as i have much work to do, so some FB, some WhatsApp reading some Mails and checking XDA now and then via Tapatalk.

I'm on latest CM nightly (official build) with CM Kernel. As an Experiment i'm currently without any Gapps, Playstore or Play Services, so this might reduce Battery Usage significantly. So far i'm really happy with the outcome and am trying to further optimise.

I've noticed, that the CPU as soon as you touch the screen locks in at 1700mHz. I really don't like that and think this value could be much lower for CM. I'm looking into Kernel Adiutor to change these settings. This should bring up the SoT considerably.

[Galaxy Note 4 General] koppee1:
Anyone else having this problem? Started a month or so ago...removing the battery changes the battery percentage/life...examples... And these are pretty consistent (I can easily reproduce):

1. Phone dies at around 20 percent. Rebooting will show bartery at 1% or less and will dia again. BUT, if I remove battery, and put back and turn the phone on, it will turn on and show 20 percent...and will last until the real 0 percent.

2. At 100 percent, if i notice a fast drain to say...97 percent. ..removing the battery and turning it on a gain will bring it back to 100..and it will seemingly drain normally.

I've tried repeatedly charging 0 to 100 and wiping the cache partition but this still happens a lot
[Galaxy Note 4 General] cavags5:
Its very strange, i change 3 notes 4 in store due the problems they had, and all 3 i charge a full charge when had 95% remove battery and when turn on had again 100%.

I think all notes do that.

But its not good to do that,remove the battery every day.

Similar problems occur for me too either calibration or battery itself messed up. And its very annoying.
[Galaxy Note 4 General] dominicstg2:
what setting do you have on the amplify
[Galaxy Note 4 General] Kinsman-UK:
Are you folks all using Fast Charging? I wonder if this has an effect on the battery over prolonged use? I've never used Fast Charging, but instead have been wirelessly charging my Note 4 since I got it (6 months ago) and the battery always charges to 100% and doesn't appear to have any calibration problems (yet!). I have never removed the battery since purchase (except once when changing SIM card).
[Galaxy Note 4 General] tmac31:
i sometimes use fast charging, i generally plug my phone around 30% and its on charge till morning.(standard charge not fast) but when i need to use it under 20% this problem happens for me 1st it was dying very fast but 1 by 1 under 15% now it goes very fast every time i check it loose around 3% and die in minutes.
[Galaxy Note 4 General] Zanr Zij:
That's normal. You battery lose about 10-20% after every year. I face the same prob like you. I bought a new original battery and solved problem
[Galaxy Note 4 General] tmac31:
Not really my battery life doesnt change much but it acts weird. I definetly wont pay for new battery its more than a normal problem ill just send it to service they should replace it.

[Galaxy Note 4 General] lisbon2004:
this is interesting.

in my note 4 the battery is degrading quickly after just 11 months.

last week the phone died at 10% battery, yesterday it died at 15%.

with another note (that is on latest official 5.1 OTA rom) it was even worse.

so the geniune battery was bought (from a certified samsung dealer) and the same thing happens - exactly like you say.

i'm wondering if it is connected with battery stats?

on rooted phones with CWM, there's an option to wipe battery stats
[Galaxy Note 4 General] tmac31:
i believe its just battery stats problem i tried my battery on a different note 4 it was working fine.it sometimes works fine on my device too like yesterday i used my phone around 1 hour after 15% but before yesterday 15%-0 was like 3-5 min
[Galaxy Note 4 General] Zanr Zij:

[Galaxy Note 4 General] tmac31:

[Galaxy Note 4 General] Zanr Zij:

My battery is draining as it is keeping the phone awake all the time. Even at night when the phone is sleeping, the awake signal is there. Therefore the CPU is running at 300MHz and thus losing 25% battery juice.

Tbh with the screen of the n4 4 to 5 hours of sot is really OK. You can lower the brightness or use some black theme. Amoled will save battery by using black themes... But there's only so much you can do. In the end its a big high res display which needs to be powered...

[Galaxy Note 4 General] supertoast92:
Something's keeping my phone awake the entire time as well. Stock Verizon edition. :(

Bluetooth seems a bit higher than normal. I wonder if it has to do with me unpairing my smart watch...even though it's no longer paired.

Edit: Heh, that was a quick analysis. Turning off Bluetooth allows it to sleep. Not sure if it's supposed to be kept awake with Bluetooth enabled or not, though. Even with nothing actively paired with the device.

View attachment 3512845
[Galaxy Note 4 General] domsch1988:
Nope, it's not supposed to. I had the same problem too. It's definitely an app keeping your phone awake while bluetooth is activated. In my case it was the MyVodafone app. Use Greenify and BBS to see which app is causing the Issue. Greenery every app you have installed. Use CPUSpy and reset counters. Let your phone sit for 5 Minutes and see if it deep sleeps. If it does, disable Greenify on one app and repeat. You'll eventually find the culprit!
[Galaxy Note 4 General] supertoast92:
Thanks! I think I found it - GasBuddy. Now my phone deep sleeps. Not sure why that app needed to do anything with Bluetooth, but that's another story.
[Galaxy Note 4 General] spexwood:
Do you have GasBuddy's notifications turned on in the app's settings? I have GasBuddy and always leave bluetooth on, but my phone sleeps. I don't have GasBuddy's notifications on though.
[Galaxy Note 4 General] supertoast92:
Just redownloaded the app and disabled notifications, and it's still holding my phone awake. Tried testing in both high accuracy and power saving modes for location, too (I tend to leave my phone on the former setting). Hmm...

Edit: I submitted feedback to the developers of GasBuddy. Apparently it's a known bug and they will be fixing it for the next update. Maybe it only affects certain versions of Android / carrier variants of the phone.

Struggling with 5.1.1 batterylife 4.4.4 netted me 8 hours sot nearly every 2 days.. time for a new battery or a new phone
[Galaxy Note 4 General] Zanr Zij:
This is what Samsung want. They did very bad job with Lollipop for Note 4. The same thing will happen early next year with Note 5.
[Galaxy Note 4 General] tmac31:
lol? 5.1 is definetly the best firmware has been released for note 4.
[Galaxy Note 4 General] Zanr Zij:
Compare to Note 5 firmware quality, of course no! Smoothness, battery life are far from best they can do. There are no limit on Note 4 hardware to make it much worse ( than N4 KK, than Note 5 ). LL is just better on visual effect but TW on Note 5 also far better!
[Galaxy Note 4 General] tmac31:
i havent tried note 5 but im using s6 edge every day there is basically no smoothness diference and battery life is just great for me 5hour sot is just worst for me. with having 3gb ram on both s6edge and note 4, note 4 also has way way better multitasking.

battery life is problematic for every lollipop device btw because of lollipop mobile data bug its not note 4 spesific
[Galaxy Note 4 General] Zanr Zij:
Try Note 5 first then come back here folk :). And do not say about Note 5 by S6E experiences. They are different. And compare between them on stock plz.

Samsung said directly to me: should not use 5.1.1 on with Note 4, 5.0.1 just better. I spent many times to find out good custom Rom for N4. There are no limit on Note 4 to make it same TW, same firmware with Note 5. But finally they did not and won't.

You can read somewhere around. There are many people complain about what Samsung doing with Lollipop on Note 4.

Sam Mobile also said about this

[Galaxy Note 4 General] tmac31:
I just dont care what webpages say but 5.1 is just cant compareble with 5.0 sorry 4.4 can atleast be better on mobile data battery life against 5.1 but 5.0 just worse in every aspect compared to 5.1. Even the 5.1 issue thread shows nothing is broken but in 5.0 alot of thing is broken like gpu, multitasking button, call screen delay.

And about note 5 its a better device with better hardware with extra ram. And i just doubt s6 edge and note5 experience differs alot besides multitasking sorry.

Ps: i just noticed you are using note 4 duos is it s805 devices? Cuz i thing my exynos note 4 runs definetly smoother and faster than my note edge with s805.
[Galaxy Note 4 General] Zanr Zij:
Seem we did not meet the point to say.

Webpage: normally don't care but with a fanboy-like webpage ( Sam Mobile ) have to complain about it, it is really big problem.

You please talk me about your real life usage, not something people, threads... . With me, nothing broken or atleast nothing big broken appear to me.

I have both Exynos and Snap, my Note 4 Duos - my wife N910C. Real life usage: no difference smoothness, battery performance!

I said A, you said B. I want to stop here for people talk abouy battery life

---------- Post added at 07:21 AM ---------- Previous post was at 07:12 AM ----------

Yep! I believe that 5.x for Note 4 not good as Samsung can do, the main point. They want to do that!
[Galaxy Note 4 General] jmcostales:
Just noticed that Amplify does not work with the latest custom Xposed Framework by Wanam. Has anyone else experienced this?
[Galaxy Note 4 General] tmac31:
im talking with my experience already, note 4 5.1.1 is just as good as s6 edge i have been using both of them long time already. if you are saying their new firmware on newer device also bad we can discuss but basically there is just no difference for me on real life. and i definetly take note 4 5.1.1 over my s6 edges. i dont know what they can improve its fast its always smooth havent had any stutter, animations always smooth. very very stable and battery life is excellent on wifi for me.but like i said mobile data is problematic cause of stock android 5.0 bug from google.

anyway im going to get note5 probably and replace my note edge cuz i never liked s805 performance and update if i see any noticable difference. but i just doubt its different than s6

and about sammobile they are just crying about themes support etc which is pointless for me anyway
[Galaxy Note 4 General] ljubimci:
First - I never rooted my phone, everything on it is pure stock.

1. Upgraded OTA to 5.1.1 SEE COI

2. Full wipe data/cache from stock recovery

3. Did 3 full cycles of discharge to 0% and charge to 100% with no using phone meanwhile to recalibrate battery system stats.

4. Disabled bloat that I dont use (Google app, Plus, Newsstand, Games, Music, TTS...), Samsung bloat, ANT services, S Voice, Flipboard, Briefing, Evernote, Pen Up, Remote, Talkback and also I'm not a fan of social networks so I disabled FB, Twitter, Instagram and messengers, I only use Whatsapp.

Wifi always on.

Data plan on.

Auto brightness +5.

No more tricks.

I suppose I get a lot by not using FB and simillar apps that drain battery in the background but however, I have other apps installed and my phone is flawless and I have no intention to root my phone at all nor change it for better soon, with 5.1.1 it just got perfect, smooth, fast and durable.
[Galaxy Note 4 General] John___007:
Got it, i am the same way, using only Whatsapp, and disabling all this Shi*'s, how program/app you use for disable the app?

How many percent of battery you upgraded the smartphone?

You use Fast charging?

In the step 3 you said that have 3 full cicles off discharge, as well without using the phone?

Tks!!!
[Galaxy Note 4 General] ljubimci:
No apps for disabling, I do it from Settings 》Application manager and enter the app that I want to disable and just do it.

Before 5.1.1 my SOT was approx 5h, 5h30h at most. Now it doesn't go under 6h30min if I dont use phone for navigation, and it can be 7hrs as you could see. How many percent is that I dont know really.

And my battery is OEM Samsung battery that came with the phone, I wouldnt put strange batteries inside N4... its a pretty expencive phone to put some chinese "expanded" batteries inside, its my opinion. I'd always go for OEM.

Step 3:

Discarge phone completely and let it shut down, then charge to 100% and dont use it while its charging.

Do this 3 times. It makes new software read battery stats properly and deletes previously saved stats that might be bad.

Ps: Ive had many Samsung phones and their batteries go very quick from 100-87% and from 5-0%. Its a normal thing for Samsung, dont let it confuse you. After 87% it starts to drain normally.
[Galaxy Note 4 General] John___007:
Really dont understand how you can take 7HRs off SOT that way :laugh:

what you do with your phone? you not install nothing?

You disable the apps before or after the 3 full charges/discharges?

You use microsd card? sorry for the questions hehe but 7 hr os SOT are Amazing.

How you managed to disallow the apps like (Ant services samsung bloat like knox and etc)? in my ROM (Poland XEO 5.1.1) is not capable, the icon disable is unusable.

Great Tks!

I have used a Note5 along side my Note 4 N910F, and the speed difference isn't big. The Note5's TW looks much much better though, and launching the camera is way faster, but overall? Not a big difference, hence why I am happily sticking with my Note 4, also because I use MicroSDs.

Hello there, since I bought my note 4 F I'm getting 4 to 6h of screen on. And ridiculously big battery drain by android system (equal to the screen usage)

Does anybody know what might be causing it?

Turned off almost all the notifications, 3g/2g, flashed many LP roms, like German (before i had a brand from Polish Orange) now I'm using German clean 4.4.4 (4 parts flashed via Odin) and it's little better..

Still,it's irritating.

Any ideas?

Battery saving without processor, few my apps (using them on my every phone)

It looks like that every single time:

I can understand that system android will eat battery, it's normal, but why such a high usage?

Thanks in advance, I'm counting on you guys!

Ahhh. On Lolipop I had a strange situation when on stats it was shown that I was using WiFi all the time even though it was turned off... Google always scanning was turned off as well.

However since I downgraded to KK i don't see it, though system android drain it's still there...

You're my last hope!

Hi, is your phne rooted? When yes, try wakelock detector or better battery stats and post your results.

I wouldnt own N4 to not install apps on it, its absurd. Of course I installed plenty of apps I use, I disabled the apps I do not use.

It is completely possible in my case to disable ANT services, was always possible not only on 5.1.1. I never said I disabled Knox, that one is not possible.

I do not use SD card cuz I find 32gb really enough, and also I use cloud services so the files I need are always available even after reseting my phone.

I disabled the apps right after the factory reset. Charging cycles came after.
