[Galaxy Note 4 Q&A, Help & Troubleshooting] bnbasarir:
That's because you are not using your phone. It's a normal behavior to have OS on top if device sits on idle for a long time.

---------- Post added at 04:09 PM ---------- Previous post was at 04:02 PM ----------

Wakelocks under OS are generally kernel related and most of the time either a wlan or fast dormancy is the culprit. If it falls under the system that means you should monitor your apps listed under that section. My best guess is Samsung Push Services or some other sort of system app that needs requests frequently Internet sockets to be open.

My device is due to arrive this weekend. I'm getting the C version, Exynos Cat 4 variant. As soon as I get it I'll try to be more helpful. For the time b3ing all of them are my assumptions based on previous experiences with Samsung devices.
[Galaxy Note 4 Q&A, Help & Troubleshooting] scoobrel:
Its been at the top for the past few days even when the phone is being used. The screen used to be at the top as soon as i used the phone for a few minutes but now the Android system stays at the top no matter how long the screen is on.
[Galaxy Note 4 Q&A, Help & Troubleshooting] bnbasarir:
Seems like it kept your phone awake only 8 minutes. Probably negligible amount of battery consumption, if any at all. I remember sometime ago system reporting fake Bluetooth consumption on G2, I think something similar happened on Samsung s S3 as well, reporting cell standby high value with no impact.

Sure when more developers will have their devices we will see some improvements and bugs discovered.

Until then I'd suggest you enjoy your device ?

With regards to post #27, about fast dormancy, on my previous note 3 I had to disable it as it was causing battery to drain. Fast dormancy is suppose to save battery but on some carries its just a battery drainer.
[Galaxy Note 4 Q&A, Help & Troubleshooting] w4mch:
Hopefully related battery issue. Please forgive if this is not in right thread.

Noticed a 10% battery drain with phone turned off overnight, two nights in a row. Third night I pulled the battery and when reinstalling it was at 100%. Finally, I left the phone on and allowed it to go to sleep overnight and again a 10% drop over about 8 hours.

I live in a weak signal area, about 1 bar, have a stock Sprint Note 4 with the S View case.

Does the power off button do anything other than sleep mode?

[Galaxy Note 4 Q&A, Help & Troubleshooting] cknewdeal:
This is my first Note, can you tell me where I can find the setting to try turning it off? I lost about 50 % over 8 hours while i slept. I just got the phone last night so I don't know it the phone is trying to discombobulate itself first.
[Galaxy Note 4 Q&A, Help & Troubleshooting] ozaghloul:
Give your phone 3-5 days and few cycles of full charge and discharge to start getting the real battery life. Its normal for the first full charge to empty out very quickly.
[Galaxy Note 4 Q&A, Help & Troubleshooting] quadlt:
No, guys... This myth is as old as our planet, today's batteries don't need any of that 'perform full cycle first' stuff. My N4 lasted as long as it does everytime on my first charge. There's really something else out there, each user gets very different results.
[Galaxy Note 4 Q&A, Help & Troubleshooting] cknewdeal:
I was thinking it might have been an app but just like OP it shows the Android OS as the highest usage. So that's why I wasn't sure. I think I'm going to factory reset my phone and slowly add apps everyday to see if it's something like an app using location services or something like that.

Maybe the screen is so efficient that the major battery drain comes from Android OS now since the CPU has to force more to push that 2k display?

I see more Android OS usage, but my battery doesn't drain. I get 5Hrs SoT with android wear and around 18h usage. LTE, location, sync on.

[Galaxy Note 4 Q&A, Help & Troubleshooting] chadlondon:
battery also draining super fast

I too am very concerned by battery life on the note 4. as a note 2 owner that used to get to work about 3 hours after taking device off charge and only using 1 or 2% power, the galaxy 4 performance I'm getting is terrible so far.

I even went to a service center and got the battery replaced and now I'm on my second one things seem to have got even worse.

Just woke up and I'm on 56%! Here's the breakdown (brand new Korean note 4 on android 4.4.4) - see message attachments for shots of power drain.

Something in the systems clearly taking a massive toll even when device is on sleep. Any ideas?

If this is "Normal" let me know asap. Today is last day of warranty.

Do you by any chance have an Exchange account configured? I was getting crazy wake-locks like that when I had my company email account configured. Solution was switching to an email client called Cloud Magic which moves the email checking server side and used A2DP push instead. I now get 4-6hrs of screen on time which I think would be even higher if it weren't for the poor reception in my home.

Yeap, seems OK. Mine is very similar most days.

An observation: it seems like most people in this thread (myself included) run their phones down to single digits, <5%. The best technique to maintain such batteries is keeping them functioning between 40-80%. Easier said than done, but in any case, if possible, plugging it in before reaching 15% and taking it out of the charger at 100 or less, should help with the battery's general longetivity. I've been told by someone who works for Samsung, but if you google "lithium batteries 40-80 rule" you'll see a lot of discussions about it. :)

[Galaxy Note 4 Q&A, Help & Troubleshooting] chadlondon:
Well any idea of what i should do?

I've had power on for about 20 mins and down to 92%. So 1% of battery equals 2 mins screen time... with only action 3g net browsing (area of full reception)...
[Galaxy Note 4 Q&A, Help & Troubleshooting] bat0nas:
We need to go down to 5% because we need exact and comparable measurements of screen time :)

Give us screenshot of your battery stats, cpu spy screenshot etc etc. Then somebody will tell.

Hey ,guys../.any news?

I got my Note 4 2 months ago.

36+hours of battery on low usage days.

But after the update, at least, I think it was after update, it just went down...

Now 3h screen on time.

[Galaxy Note 4 Q&A, Help & Troubleshooting] Silberpfeil3110:
I also checked out my battery behaviour this night and was very disappointed. Although my phone was in flight mode and every peripherals and services shut down, today morning my phone was crying for energy. So I made a quick investigation in my power diagram and found out, that "Android OS" requested a wakelock during the whole power-on time. So I installed "CPU Spy" to check in which states the phone was really over the whole charging period. I couldn't believe my eyes. Although the kernel should do it's job good, cause most of the CPU times are in lower freqeuncy states, the deep sleep mode was never activated.

Therefore I installed an app called "Wakelock Detector" to check out which apps could cause that. I found out, that S Health had a big amount of wakelocks and also active-time, so the first thing was to disable S Health. After some minutes I checked back, but nevertheless still no deep sleep time in "CPU Spy".

So I searched around and found another one arguing about the wakelocks and that they could be the products of some programming issues concerning WiFi. The should be gone, after turning off WiFi and rebooting yout phone. And it seems that he was right. I waited some time and hooray, "CPU Spy" listed the phone state "Deep Sleep" the first time as an active state and also with the major active-time. So at least that was some step ahead. (I have to remark, that S Health was already unfrozen at this time, so S Health should not be responsible in any way.)

The next step was to reactivate WiFi, leave it on and set the phone on standby. After some time I checked back again the phone showed even more deep sleep time. So that was an improvement. I reactivated everything and waited some time... Deep Sleep all over the time. Can't figure out for now, if it was S Health, WiFi, or anything else that caused the wakelock for sure. At least the reboot helped. I'll check that out on a long-term test, maybe I get some further conclusions.

Bro

if done a recent Mod or Rom alterations,there is a chance for this battery sucking issue.

May be below will fix the Issue:

[*]1) Flash Agni control mod or Recovery mod(TWRP / CWM)

[*]2) Do dalvik and cache wipe using Agni control or by recovery Mod(since this will stabilize ur System for new Mod or Rom).

[*]3)Reboot the system

[*]4) Run your system under power saving mode.

[*]5) Reduce the number of Auto start Apps(clean master can be used to done this).

[*]6)Location service and Sync must be disable unless its used frequently(frequent use will leads to a battery drain now For that only solution is a DC generatorr :laugh::laugh:).

[*]Ensure GroupPlay,NFC ,Wifi direct,screen mirroring are disabled if the ur gadget supports this.

[/LIST]

Reboot your system once a month for regular calibrations.

Let's See whats happening

Note 4 'android system' battery drain

I found that by disabling 'Smart network switch' in Wi-Fi of my att Note 4, battery consumption has gone down considerably. This is likely because my wireless internet is crappy, which causes internet to switch between wifi and 4G too many times, eating battery.

Second: I disabled the 'always allow scanning' in Wifi advanced. This too will consume battery.

Third: I set locating method to power saving (wifi only) under Location. When using maps, I'll change it to GPS, but then change it back to power-saving.

The problem is that location and the other functions listed above reside in 'android system', but they are called upon by other apps, notably 'Google Services'. This will mislead you because you would have no idea that Google Services is the real culprit since it appears lower in usage on the battery page.

Here's a thought (which I haven't tried yet): Samsung remote controls could also be the issue because it also uses location, which resides under 'Android System'.

Also, for the love of saving time, would you all please stop with the cache-wiping and factory resets? Those are just mushroom-cloud ways of resolving issues as opposed to targeting the actual problem.
