Hello Everybody

I hope you can help me.

From 1 month in the battery stats the bluetooth has an i high battery consumption as you can see below.

The only device connected is Huawei Watch but at the beginning this situation never happened.

Can you help to find the rootcause?

thank you

Hi!

I have a problem with a brand new battery. I bought it a few days ago and i get a maximum of 3h SOT. I tried to calibrate it. I managed to take it to 0% once but now shuts down at 12% and I cant get to 0 anymore. I installed AccuBattery and it said that after a full charge has 85% of the capacity. The battery drain when I am using it is very very bad and in the battery section in settings all are normal...it doesnt show any unwanted apps drawing the battery.

Thanks!
[Galaxy Note 4 General] StevePritchard:
Apologies for the delay, but just in case you are still suffering from this problem, or anybody picks up this thread in future...

Excessive Bluetooth usage often seems to be down to an App. I've seen reports of GasBuddy and CVS causing the problem... https://www.reddit.com/r/Android/comments/4snlyc/psa_the_gasbuddy_and_cvs_apps_cause_massive/

However, the culprit for me was AccuWeather (Platinum). I reported the problem to them in March, and although they acknowledged the issue, it wasn't fixed. I recently sent them some more info following a review I placed on Google Play, but to my knowledge, it isn't fixed as of the end of May 2017.

Cheers,

Steve.
[Galaxy Note 4 General] zip88:
Dear Steve,

Really thank you for your reply.

Unfortunately i was forced to bring my note 4 to the samsung assistence.

I don't know the main root cause of the ssue but this magically appear 10 minutes after the hard reset.

I tried without success to install other firmware but nothing is changed.

I hope that the will change directly the motherboard.

I will keep you updated

thanks again

My phone turn of when i have more battery and charging from 0%.
[Galaxy Note 4 General] chrisman99:
On stock marshmellow 6.0.1. The original battery I got slowly started dying at about 8% and then gradually got worse to dying about 45%. I tried another battery which is a Chinese fake which always goes off on 0% only with this one it will only charge up to about 77%. It will only charge up to 100 if I take the battery out and put back in. What was 77% will then show up about 98% and will then go up to 100. My question is before I buy another official battery is it this because the batteries are 1 old and 2 fake or is it a calibration issue? If I swap and change these batteries the same specific charging issue to that battery occurs.
[Galaxy Note 4 General] lisbon2004:
Looks like a fake Chinese battery that only has 50% of the declared capacity, or even less.
[Galaxy Note 4 General] Mandark52:
I am currently facing the same issue. Mine dies at 6% mostly. The battery is dead. Just for assuring yourself remove the battery and place it on a flat table, spin it. If it spins for multiple rounds it's probably swollen and dead and we need to replace it with original.
[Galaxy Note 4 General] chrisman99:
I got a new battery in the end and it's fine now.
[Galaxy Note 4 General] Kinsman-UK:
[DELETED] Sorry, wrong thread.
[Galaxy Note 4 General] myka_1997:
are the note 4 battery orginal can through the day last the battery? show ur screen shot screen of time and stand by mode. please answer ME!!!!!!!!!!! i worried about the note i wanna buy, but i dont know can last through the day until charge phone?
[Galaxy Note 4 General] josuts:
Hello!

I would like to ask if anyone here had bought an extended battery without the extra cover from the batteryupgrade.com and if he is satisfied with it!
[Galaxy Note 4 General] Kinsman-UK:
I'm using a genuine Samsung battery bought from their UK store this year - I'm on Exynos N910C. Getting 5-6 hours screen on time each day. Sorry no screenshots to hand, but there are plenty of them in this thread. Even if it didn't last through the day, a big bonus of this phone is the removable battery, which means you can have a spare on hand fully charged to switch in at any time.
[Galaxy Note 4 General] Sakab:
What ROMs can you get the most, most display time? Stock or Custom? If custom then exactly which ROM? Kernel, modem, bootloader affect the result? I have a new 1-week original samsung battery, Ditto Note 7 ROM, but display time is up to 2.5-3 hours. Even though WIFI, GPS, BT were not turned on, the brightness was 20% and still so low. I have n910c.
[Galaxy Note 4 General] Kinsman-UK:
This is fully stock, not rooted. Brightness about 20% most of the time, sometimes higher. WiFi, bluetooth always on (I have a smartwatch). I use Package Disabler to disable bloat, Greenify to hibernate unneeded apps. 2.5-3 hours seems low, could be the ROM or a rogue app, or maybe just a bad battery (are you sure it is genuine Samsung?). I use GSAM Battery Monitor Pro to identify processes that eat up battery - you don't need to be rooted, you can enable extra features through ADB (see https://plus.google.com/+GeorgeTanner/posts/gT5f7XntmEu).

I had a year old Samsung battery previously which didn't seem as good as my new one, it was giving me 3-4 hours SoT - but I did a factory reset (first time in two years) and bought this new battery from Samsung UK and now back to the 5-6 hours I was getting when I first bought the phone.
[Galaxy Note 4 General] sefrcoko:
You have over 200 pages of content here with that info ;)

...yes the note 4 battery has always lasted through the day (for me at least). My phone is getting old now but I get about 4 hours SOT for a full charge at the moment on stock fw (rooted, xposed).
[Galaxy Note 4 General] imeem:
my note 4 (1.5 year old) on stock 5.1.1 lasts around 20 hours according to Battery Usage with 3-4 hrs of sot. it used to last longer on a older build of 5.1.1 .
[Galaxy Note 4 General] hopelives:
I have 3 years old N910C. My daily routine includes 1,5 hours music (Spotify), 30 minutes video (Youtube or others), 45 minutes reading and other app usages. I get 3-4 hours of SOT. My phone has stock MM based, heavily debloated SimplROM. I'd like to get recommendation for ROM, kernel and app combination to lengthen battery time besides SOT.

So, which combinations do you recommend?
[Galaxy Note 4 General] w41ru5:
I have the same 910C and used AirRom, while now the Nemesis Refined is the daily driver.

Both of them with great numbers in battery life.

On the aside note, I'm not a friend of any google app, including framework. Which google services are battery juice thirsty. Like a lot.

So my phone runs w/o google services.

But that's something not everyone is willing to take out.

Both ROM's with SpaceLemon kernel - thanks to [MENTION=1108430]LukasAddon[/MENTION] (extraordinary job!).
[Galaxy Note 4 General] hopelives:
Thanks for the answer. But how can you do without play store for instance?
[Galaxy Note 4 General] w41ru5:
F-Droid, Apkpure, Aptoide, etc. Most of them are websites with many apps. Also Apkupdater app and it tells you what apps have new versions.
[Galaxy Note 4 General] hopelives:
Thank you very much. I'll try as soon as I have time.
[Galaxy Note 4 General] imeem:
hey guys, how's the battery health on your phone? bought my phone brand new and it is almost 2 years old.

the app i used is accuBattery
[Galaxy Note 4 General] w41ru5:
Be careful on what you do, back-up your data and read more before you try out.
[Galaxy Note 4 General] hopelives:
I know those procedures, thanks again.
[Galaxy Note 4 General] hopelives:
I guess your battery is about to die since I passed the same stages after two years. Especially if you use quick charge battery lasts in a year.
[Galaxy Note 4 General] imeem:
i actually never used quick charging, i either charge via usb or pick the slowest charger that matches stock voltage. it's weird how my 3 years older Nexus 4 has the same battery health as my note 4.
[Galaxy Note 4 General] dacorsa:
Hi guys,

my note4 have a big drain with system process in BBS, why?

can be an oxidation of the motherboard?

THANKS
[Galaxy Note 4 General] MaXi32:
Use package disabler to disable bloat without root ? I don't get it.
[Galaxy Note 4 General] Kinsman-UK:
I moved on to a Note 9 earlier this year - but just to answer your query, no, you don't need to be rooted to use Package Disabler. I am using it on my Note 9 too, and it is not rooted.
[Galaxy Note 4 General] MaXi32:
When you say "debloat" do you mean, removing the system app or disable the app ?
[Galaxy Note 4 General] Windroid-user:
He means disabling. Because he is using an app called package disabler.

Anyway why are you not rooted?

If you want a stable, debloated stock rom experience go here: https://xdaforums.com/note-4/snapdragon-dev/rom-bob4-devbase-multi-csc-safe-bloat-t3033881/page357

You can flash the rom without root if you want. Have a good read (using browser is better) and ask anything you don't understand.
[Galaxy Note 4 General] MaXi32:
Sorry, maybe I'm a little bit confused with the definition of bloating. AFAIK, disabling a bloatware app doesn't mean we debloat the app completely because we still got storage bloated! So this is more like disabling the app from running. Thanks for explanation. The link that you have given, I already tried. Thank you!
[Galaxy Note 4 General] Windroid-user:
I would personally consider simply disabling the bloatware not debloating it, because like you said it is still there on the device taking up space. But people do consider this as debloating as I guess it will be out of sight not storing your data relating to the app. Only the app data.
[Galaxy Note 4 General] louisJJ:
Hi everyone, do you know where to find good batteries for the note 4 (N910F in my case) ? I am struggling with bad batteries.

Thanks for your help
[Galaxy Note 4 General] EP2008:
Just finished the PCMark for Android battery test on both my note 2 and note 4 and I'm so disappointed.

I'm hoping that others can test there's too and post the results :

N910U Exynos FULL BRIGHTNESS

As a comparison, my Note 2 got 5:40 on the same test at full brightness on a 2 year old battery.

[Galaxy Note 4 General] ShadowFlare:
Hmm, did you run this test under Flight Mode? If we're going to compare battery life test using a benchmark, best to compare at the same level. I'd like to see how this fare between Exynos and Snapdragon.
[Galaxy Note 4 General] alex989898:
I'm not disapointed with the battery life of the Note 4. That's m'y first charge but I'm already impressed.
[Galaxy Note 4 General] ShadowFlare:
Those are good results, Snapdragon or Exynos?
[Galaxy Note 4 General] alex989898:
I have the snapdragon Note 4. My girlfriend too and she has roughly the same battery life.
[Galaxy Note 4 General] domanwrc:
I have 910f.

can't get more than 4-4:30 SoT.

I see that a lot of people have the same issue.

I've tried root and custom roms. Nothing changed.

I am dissapointed with my note4 battery.
[Galaxy Note 4 General] Hendrickson:
Same, but I can't get over 3:30 hours. I'm thinking maybe some chipset bins are higher and therefore use more power than others?

I have a 910U and the battery runs out about 1 day before my LG G3...And my Note 3 was much better than this!
[Galaxy Note 4 General] domanwrc:
Some people get 7-8h SoT.

Some get 4.

WTF??

I am really confused and have no idea what is the problem.
[Galaxy Note 4 General] alex989898:
What is worrying me a lot is that no matter what I do, android system is the first or second battery consumer.

Even when I use the screen a lot, Android System is never far behind.

I know that the GNote 4 screen is very power efficient in most uses but it seems to me that Android System consumes more than it have to.
[Galaxy Note 4 General] EP2008:
Both my phones had the same features enabled. I don't want to test with stuff disabled because that's not how I use my phone, and if people (and review sites) are getting 7-12 hours of SOT, I want to know what the heck is going on.

Right now, I can't even make it through the day without having to charge this phone and even then, I'm limiting what I do in order to save battery life.

[Galaxy Note 4 General] alex989898:
Reviewers test their phone with optimal conditions (Good signal and connection, no movements, screen with fixed brightness setting, ...) and with protocols that don't mirror real life use.

[Galaxy Note 4 General] ShadowFlare:
I believe, when reviewers test the SOT, they put it in flight mode so that the test is on the same level with other devices. They would play video from local memory / SD Card too. Unless they start testing video playback time over WiFi or 4G/LTE.
[Galaxy Note 4 General] alex989898:
It depends of the review.

GSMArena use flight mode to test video playback and WiFi to test Internet browsering. But other reviews use LTE networks for their test (some sites also test video playback with streaming app like Netflix or YouTube).

So, it really depends.
[Galaxy Note 4 General] EP2008:
So did I - same wifi connection, no movement, fixed brightness... It's a hell of a difference between 4.5 hours and 10+ for web browsing! And when I look at other Note 4's on PCMark, they're getting just under 6hours. Don't know what's going on here, but I'm not happy.
[Galaxy Note 4 General] Lodix:
The screen on time depends on what are tou doing while the screen is on.

It is not the same whatsapping or gaming.

My friend had note 3, now he have note 4. He says same thing. A lot better battery in note 3. Now he have bought Ip6+ and it have 2x better results than with n4.

There must be "something"! But what it is? :(

Same as you I can't have a day without charging with my n4 :(
[Galaxy Note 4 General] tmac31:
Im using 6+ and note 4 together pretty much both are same for me im getting around 40 hours standby and around 6 hours sot always its getting better and better in everyday. And 1 thing i notice when you use fast charge battery goes down faster dunno maybe just battery settlling or programs updating. But i dont use fast charge lately and its better in last days.

I didnt drop to 4.5 hours anyday i should add it. And i used note 3 note 4 is better for me in battery but i dont play games it could wasting more juice with full power. I dont use power saving i should add it too.
[Galaxy Note 4 General] domanwrc:
So you are one of those which have proper battery results.

I'd hate to know what the battery stats were like before that "battery improvement" update that came out last week! :eek:
[Galaxy Note 4 General] cathain:
I wonder if the people who are getting 5+ hours sot could list what they have disabled if anything?

I'm averaging about 3.5 hours sot. I have disabled shealth and turned GPS, Bluetooth and nfc off. Screen brightness is on auto. Android system is still the main battery user.
[Galaxy Note 4 General] hohoXD1233:
50% left, 6hrs on battery, SOT of 1hr 41m. This is just horrible, thought I had left my poor battery woes behind with the nexus 4. The screen is always the main culprit, with android usually being second.
[Galaxy Note 4 General] EP2008:
I'd also like to know if they are rooted and using the Xposed framework. There's got to be something about these wild variations!
[Galaxy Note 4 General] alex989898:
I have WiFi enabled, GPS on "energie saving" (I don't now how it's called in English), synchro on and screen on Auto brightness (0).

No special app or setting.

I'm not rooted.

Fast charge is disabled because I'm not sure that fine for the battery lifetime honestly.
[Galaxy Note 4 General] domanwrc:
maybe it is hardware problem?
[Galaxy Note 4 General] Hendrickson:
So do I, there is no way I could get 7-8 hours on screen time. Can't get even 4 hours. Is the Exynos that bad? I thought it was meant to be even better on the battery.

I do have root and Xposed installed. Maybe this is the issue and I'm fast charging.
[Galaxy Note 4 General] EP2008:
How would we diagnose that?

Everyone who can, needs to do a standardized benchmark (Like that PCMark for Android I linked above) in order to really see what's going on.

The more numbers we pool together, the more accurate the data will be. Right now, there are too many variations on how people use their device.
[Galaxy Note 4 General] Vangelis13:
Attached what I've frozen (so far) with titanium backup.

Further, install this: https://play.google.com/store/apps/details?id=cn.wq.disableservice

Then, go to System Apps -> Google Play services & disable the stuff on the attached pics.

Again, go to System Apps -> Location Services & disable everything. While at, disable the yahoo weather thing too. + Fused Location.

Bad signal, crappy wifi, all add up.

We'll have to live with this until roms & kernels come out..

[Galaxy Note 4 General] EP2008:
For those who are getting long on-screen time, what brightness is your device set to?

I'm going to re-run the PCMark benchmark at 50% brightness and see if the score improves, but I usually keep my device on auto and find the battery to be poor.

Android system is killing your battery just like a number of other users. Are you sure you have disabled location reporting? Location at power saving shouldn't be detrimental to the batt life but high accuracy will be.

Google play services is the biggest villain in this, followed by location.

[Galaxy Note 4 General] ShadowFlare:
Thank you :)

Yes, this screenshot reveal the secret to why some have great battery life while others don't, that's why IMO this is the most important screenshot to take when comparing battery life.

BTW, are you on 3G or 4G?

When others' Note 4 are struggling with signal, Android System usage gets really high, which is weird. Shouldn't it be Cell Standby usage that gets high?

Samsung's power management is really weak in this area, I've started noticing this when I was using Snapdragon Note 3 on 3G then upgraded my contract to 4G. Battery took a nose dive especially when I'm in the Underground train, phone gets warm, battery gets drained from the phone trying hard to get a signal. I'd lose 3-5% battery in just 30 mins during that journey. Same thing happened with my Galaxy S5 Mini, I had to put it to Flight Mode just to save on battery.

I'm currently using Sony Z3 Compact, and power management on this phone is superb, on the Underground it would only spend 1% battery during the 30 minute journey. 4G signal is terrible in London, it's only like 1-3 bars in 80% of London, and it's pretty much like that at home and at work. The battery usage this thing actually on 4G is pretty much the same on WiFi as I have observed the 2 weeks I have been using it, so I don't even bother switching On the WiFi. Even over night it would only use 1-2% battery. I remember my Note 3 drain a freaking 5-8% battery over night on 4G, only way to save it was to connect to WiFi whenever possible.

The Note 4 would be great if Samsung would get off their arses and optimise the modem radio power as Sony has done to their phones.

I read a lot of comments talking about a lower efficiency of the Exynos's battery. But I think there is still no real facts to support this hypothesis... am I wrong ?
