You dont have flash content in browser and you have caching too and loading in every 10 sec probably enough if not more demanding on cpu than touchboost. And besides gsmarena other teats and even samsung claims 11-12 hour browsing time for note 4 i just dont understand how you claim its not possible i wont even understand i guess. Btw if you see polos usage he doesnt even let phone to cooldown he just constantly use no waiting nothing im sure if you pull out the charger and start browsing constantly you will definetly pass 6 hours very easyly. And i never defended him he just exaggrate his scores he definetly doesnt have normal usage but like i said browsing on wifi with low brightness definetly can pass 6 hours easyly. I use pedometer, mobile data alot brightness on +10, 1hour phone call, sync for 3 mails and i can still reach 5.5-6 hours unless mobile data comes how can you say 8 hours sot is not possible in an abnormal usage i wont ever understand, its not possible in normal usage but its just POSSIBILE in some scenarios...

Let me guess, you can't achieve it therefor nobody else can achieve it...we've already had one of you desperately trying to claim what they can get nobody else can, yet many of us have.

Anyway.

This is probably the best SOT I have got, it was on the 1st Lollipop ROM, this was with CPU Power Saving, using Opera Mini and watching the the 2nd season of The 100, WhatsApp and Instagram.
[Galaxy Note 4 General] gekkehenkie11:
Hehe yeah this indeed sums it up. 11 hours screen on time web browsing, that's simply hilarious. If I cared enough, I'd put my screen on lowest possible brightness and then just put up a 100% black photo, put the phone into airplane mode and limit the CPU to max 300 mhz. I'm sure I'd get a screen on time over 24 hours (theoretically it could even last 3220/(34+76) = 29.5 hours). And I'd post it here, just like Polo troll and I'd say I did normal web browsing and that not touching the screen during web browsing is normal anyway. And when people ask for proof like a dumpsys log and cpu statistics, I just dont give it to them or I'd post a log and cut out all the interesting things and I'd tell them that's what they asked for. So that they wont be able to see that I limited the CPU and just did nothing.

But then again, I don't care enough :)

People who claim more than 6 hours doing 'normal' web browsing are funny.

Thanks [MENTION=3296134]gekkehenkie11[/MENTION], I tried to contact the person. It's a very strange problem. I hope it's not hardware related, don't wanna miss my note 4 ;)

[Galaxy Note 4 General] sPEADy:
Worst thread ever not in this forum but on the other forum as well. Where everyone is trying to prove my "**ck'' is bigger than yours, who cares.
[Galaxy Note 4 General] gekkehenkie11:
Very nice put :) It's exactly like that. People posting 6+ hours think they have a better phone than the others. Or were very smart to configure it in some specific way. "LOOK AT ME I HAVE MORE THAN 6 HOURS SOT". LOL. While the truth is that everyone's phone is the same. There might be some minor difference exynos/snapdragon but who cares. And then there are of course some people who just have configured it in some dumb way, like 'wifi scanning always available' or they autosync all their accounts. Or they have their home wifi network misconfigured, waking up their phone all the time and /or they have some apps wakelocking. Or they run a torrent app and wonder why they can't get past 4 hours SOT.

But most people just will have a normal functioning telephone. And then, the ONLY differences are: what do you do during your SoT, how much brightness do you use and how white is your screen ? And of course some people like to limit their CPU performance, either by putting it into CPU power saving or just use another CPU governor.

So that's why this thread indeed sucks in the first place. It's totally useless. Not sure what I'm even doing in this thread, what a waste of time.

Going to do some programming again, finishing up with the low light photo mode and RAW photo mode in our cyanogenmod :)

That is pretty good.

Are you happy with it? Apparently the battery life gets better in 5.1.1, so it can only get better from here on.

BTW, how long have you had this new Note 4? If its a day or two old then your battery will get even better after a few more charge cycles.

Talks bull****! !!!!

I'm a heavy user with bobcat rom and dark theme

All usual apps fb email youtube plenty of chrome usage

I get between 3.5 and 4.5hrs sot

Never seen over 6hrs tried my best to achieve it but never managed!

This guy talks bull**** don't understand why people need to talk **** like this. I've even bought the zero lemons battery when it 1st came out and couldn't get 10 hrs sot with that and think it was about 10000mah can't remember now because I ain't used it for ages as it just made my phone resemble a brick lol

That is excellent :)

It is indeed possible with heavy usage. My suggestion is to throw the people who do not want to believe you into the Ignore List. I posted everything from usage stats, CPU Z to show my battery is stock for those who claimed it wasn't (they went very quiet) and dumpsys and they still did not want to believe it, so rather just ignore them and enjoy the excellent battery life. :D

I have had my Note 4 since launch and to this day the battery life amazes me, my previous Androids could never achieve such numbers with less usage, yet with my Note 4 I have to try drain the battery so that when I go to bed its at less than 30%.

1) See if you can recognize any rogue services from something you installed, which keep the device awake. Go to Settings/Apps/Running, see if there's something there that you don't like. Uninstall/freeze/disable to test.

2) Set Google Location to "battery saving", and Google Location Reporting to off. Usually, Google Location Reporting is the single biggest battery drain service you can have on a stock device.

3) Go to wifi settings and disable "turn off wifi after long periods on inactivity." I find that option to drain the battery more because it keeps switching LTE data on and off when the device needs to be sleeping.

[Galaxy Note 4 General] EP2008:
Prior to a factory reset (which I was hoping would correct these wakelocks), I froze quite a few system apps, greenified stuff and performed my general optimizations (to mirror what I use on my Note 2), but they are still high.

Those other suggestions limit the usefulness of my device, so I don't want to go through that. These wakelocks are abnormal, but I may block some services that show up near the top.

[Galaxy Note 4 General] nabbed:
I don't know what you mean by "limit usefulness." You don't need GPS on all of the time, only when actively doing car navigation, so you can just turn GPS on and off with a button in quick settings. Otherwise, Android can happily do the location service through wifi/cell tower within a couple of hundred feet, without draining the battery by using GPS.

And Google Location Reporting does nothing by report your location to Google constantly. So that they can spy on you and serve you location specific ads, or report your travel habits to national security services/police. Turning it off doesn't impair your ability to allow apps to get location.
[Galaxy Note 4 General] EP2008:
Not to derail the original topic, but...

I use GPS daily to tag photos and notes. It's quite inconvenient to toggle this on and off several dozen times a day, so I'd rather leave it on.

I use location reporting for google now and to track my phone if it's lost. Disabling that would cause issues.

But I think the point is, I never had to disable those and my standby time has been phenomenal. I now the Note 4 is capable of better, so I'll keep looking to see what else is up (like those kernel wakelocks I just posted).
[Galaxy Note 4 General] nabbed:
I'm pretty sure you can geo-tag photos without GPS, by using those "battery saving services" - I just took a photo and got the gps coordinates that are about 40 feet away from my actual location.

As for location reporting, I'm not sure if you need it to be on or off for tracking a lost phone. I know that I keep mine off because 1) privacy concerns, 2) it really keeps your phone awake a lot and drains a lot of battery. I don't know what version of Android your Note 2 was running, but Google has changed a lot of functionality in google services in KitKat, and these wakelocks are some of the side effects.

EDIT: have a look here - the only mention of your worst wakelock in google search

[Galaxy Note 4 General] markyboy81:
I've had issues with hunting down wake locks before and I vow not to bother again, because you just end up beating yourself up not being able to find the cause. I've tried hard resetting and this hasn't fixed the issue either. I've tried deleting the cache partition, hard resetting again, and then all of a sudden wake locks aren't an issue and I'm getting awesome standby time again, for no apparent reason,and with pretty much everything enabled.

I'm reluctant to turn anything off now as I know even with it all turned on, it shouldn't drain the battery that much.

Not that any of this is much help to you but just thought I'd share my experience.

There is probably no fix for that.

Yeah, but I've disabled LTE because I get crappy signal and my mobile data bandwidth is too low for LTE speeds! LOL

[Galaxy Note 4 General] EP2008:
Thank you! Should I assume that the high wake time is normal for a display driver (with the screen OFF)? Seems very abnormal to me and it certainly affects the wakelock awake time.

Hi Everyone

Just needed some opinions on my battery life

16h10m - 23% Battery Remaining

5h11m - Screen on Time

Screen - 33%

Android System - 21%

Android OS - 11%

Loving the phone still, but I'm having some monster wakelocks at the moment!

The phone's been off battery for 14h 34m as I type this, and has been awake (wakelocked) for 51% of that, so that's over 7 hours of wakelock today.

Roughly 5 hours of those (!) are one processes "wlanrx_wake". Now this only seems to be a real issue when I'm at work (in a university), and I guess it's something to do with the network pinging/waking the phone.

Does anyone more knowledgeable than I have any suggestions (other than to turn wifi off) as to how I can try and manage this?
[Galaxy Note 4 General] JJ2525:
To my knowledge, this has to do with an app you have constantly polling the internet like a Twitter or Facebook, something of that ilk. There are 2 similar wakelocks, one pertains to wifi polling and the other to mobile data, yours is mobile data.
[Galaxy Note 4 General] lbreak:
Most Samsung phones have the same issue whether your on Mobile Data or Wifi, Wlan or (name for mobile wakelock) continously wake your phone and cause battery drain. Same issue on my N3, haven't been able to fix it in a year.
[Galaxy Note 4 General] Deadric007:
Hi it worked but i dont see any changes actually just that the build is firekat but not nova launcher or other extra apps. Is this normal?
[Galaxy Note 4 General] Graivite:
Yes sir, it's normal. The thing is that you get a stock looking rom, but the beauty is inside it. You won't notice any difference in UI. It's optimized, rock stable and very battery efficient. Why it is without any fireworks? Because FireKat suits needs of all kind of people. You get base and you install whatever you want. Remember to install Xposed, Wanam and disable DVFS. Gives huge boost in performance and lowers the temperatures.

Personally I just disabled a lot of apps I do not use and rom does its magic. Day to day I can achieve easily 6+ hours.

For further questions please send me a message. I do not want to spam too much in this thread.
[Galaxy Note 4 General] SnoopBok:
For some days back to stock, but I'm encountering the same problem, still the weird wakelock :( although my battery seems to drain less in standby. Visited the store where I bought my Note, he advised me to contact Samsung first. I will contact Samsung and report back here.

Anybody else seeing this wakelock in their batterylog?:

+running wake_reason=0:"unknown"
[Galaxy Note 4 General] StevePritchard:
One thing I would point out is that a new battery can work wonders. I recently replaced my battery (the old one pretty much lasted all day for me, but I can a couple of instances where the phone would simply die at around 18% full), and the new battery means it easily lasts all day and then some.

While there are obvious problems and differences with wakelocks on apps, ROMS, etc, you should be aware that comparing one person's battery performance with another's might be more down to the condition of the batteries than anything else.

Cheers,

Steve.

Stock BOG1 with some apps removed and lowest automatic brightness. No power saving mode, and everything on auto-sync. Oh and location history turned off and location set to high accuracy. :good: Pretty interesting to see that I get better battery life using a stock branded rom and kernel than I get with a custom debloated rom (Wanamlite) and custom kernel with -75mv for all clockspeeds (googy_anas).

+1000!

This is why I do not bother with Root anymore and all that tweaking. I discovered this with my S3 I9300. I tried countless ROMs and eventually went back to stock, same with my S4, and with my Note 4 I never even bothered with ROMs. Rooted my Note 4 once to try change CSC and then loaded a stock ROM and Unrooted.

Your results seem similar to what I get without power saving.

As I said it occurs when battery is used for a longer period of time. Yeah he can change the battery if he is not comfortable with it. But if it occurs in note 5, he definitely needs to return it.. And change with another.
[Galaxy Note 4 General] jmcostales:
To add to this, the quick charger that came out-of-the-box with the phone is not being detected anymore while plugged in. Is this also a battery issue, or firmware issue?

[Galaxy Note 4 General] HotShotAzn:
After reading here and on other threads/forums that people can get 5-7 hours of SOT AND 1.5 - 2 days in between charges, I really started to hate my battery (so I thought). What I am realizing now is that everything is so different from one phone to another that it is pointless to compare using other people's data as a baseline.

One guy claimed he was getting over two days of usage and 8 hours of SOT. I called BS. He posted screen shots. Means nothing to me. I can make screen shots like that as well. My wife was getting double my battery life but she has different apps and usage pattern than me.

I got an Anker extended battery and some days it would be dead by the time I went to bed with 5 hours SOT. Some days, it would be at 40%. I figure something was up. After googling my ass off (and two reformats), I reformatted my memory card and did not copy back some PDFs I had. I switched back to my stock battery and charged over night.

That made a world of difference. Indexing was never at the top of my list of services/apps running. I'm hoping I am not seeing the placebo effect. My only goal for this phone is for me to use it as it was meant to be used and not have to charge it until I went to bed that night. I'm keeping the Anker battery for now but my awake usage is the same as my screen. This was never the case before.
[Galaxy Note 4 General] azuldio:
Sometime back even I faced this issue or at least something similar. I was using the stock charger and fast charger was working well and fine... One day it stopped working that is it was charging but not fast charging... tried everything possible.... thought it was a problem with the note 4 itself.... but fortunately I tried changing the USB cable.... and it started fast charging again.... figured that it was a problem with the cable itself... apparently fast charging works with only a particular type of cable and if the resistance or internal wiring gets damaged, it will stop fast charging (as mentioned to me by the local Samsung service center)....

So I suggest you try changing the cable and see if that helps
[Galaxy Note 4 General] dzebrys:
hi, relax, the clue is to have phone gone sleep when you sleep, not letting Google doing dirty things on the side. when you achieve this you will be surprised independent of personal usage. how much sot you gain is irrelevant, most important phone will eat literally nothing when screen off so that battery is only for you not uncle goo[emoji41]

Just google "mobile radio active bug lollipop" and you will find the answer.. It's bug in android 5.0 and as of now it's haven't been fixed even in android m.. Supposedly this affect all android devices running lollipop and above..

Also when you go on a lot of walk and bring along the phone with you there will be a lot of ssp wakelock and ssp sensor hub wakelock, even if you have disabled pedometer counting in shealth.

These are imo why note 4 battery sucks when you are out and using 3g. Don't forget that bad signal also has big effect on battery consumption :)
