My battery results. 2.7 days with 5hr SOT. no power saving All stock no root. All I did is disabled location services (maps and Google now still work fine) and disabled all the bloat I could through the stock app manager.
[Galaxy Note 4 General] Lodix:
5 hours screen doing what ? Whatsapping ?

And you have plane mode half of the time ??

Anyone using xposed try and get appops and disable keep awake and wake up for Google play services might help reduce some wake up issues caused by Google play services. On the OPO this is built in and works great.
[Galaxy Note 4 General] BooBoo_el_Locco:
Can you tell me how to disable location services without root, step by step? Thank you
[Galaxy Note 4 General] Colnart:
two finger swipe down notification bar and uncheck Location
[Galaxy Note 4 General] 2ndammendment:
Settings > Location >Google Location Reporting > Set both to off.

No. Doing that will disable the GPS and you will lose navigation and some google now function. Google Location Services is something else.

Web browsing, texting, youtube, facebook. You know, phone stuff.

And no.......no airplane mode at all.

Literally everything that can be disabled which I don't use(I left S-Health and smart remote etc). Theres only so much you can do without root. It will only let you disable a handful of apps.
[Galaxy Note 4 General] ShadowFlare:
The mobile network signal on the screenshot above, the white gaps, especially the large whit gaps usually means the mobile radio is switched off. A no signal would be indicated by red bar. Can you tell us what state the phone was in during those white gaps?

[Galaxy Note 4 General] gbiggie:
Had a long day this past Friday..work then a 4 hour trip up north. Brightness was around 85%. I utilized power saving and ultra power saving a few times to try and save juice until we arrived at our destination. Pretty pleased with the result.
[Galaxy Note 4 General] Allesa:
2nd charge... 910H (3g)

Wifi on almost all the time.

Will try using mobile data more tomorrow..

I found out on the first charge that samsung account sync somehow stuck, removed samsung account.

Deffo 4g signal destroying battery life. Turned it off and is much better... is there a faster way of toggling it between 4g and 3g other that going into settings every time?? Like a widget??
[Galaxy Note 4 General] Zanr Zij:
I'm quite happy with my Note 4 Duos N9106W feature only 3000mAh
[Galaxy Note 4 General] alirey:
There is a great tool for that. It called smart network and it's a xposed module from wanam.

Your network switches automatically to 2g from 4g if screen is off. (And many other things)

One of the best battery saving procedures I found.
[Galaxy Note 4 General] an_xda:
What are the potential consequences of disabling these?
[Galaxy Note 4 General] 2ndammendment:
I noticed that as well but mobile data was always on. I use the Google now hot word detection even with the screen off so I need to keep mobile data enabled for that.

This isn't a grand jury trial lol. I wasn't using airplane mode.

Maybe some Google now features but everything I care about still works including Google now(android device manager, maps etc.)
[Galaxy Note 4 General] Dan1909:
Went into CPW this afternoon to get my handset swapped out, annoyingly (after about a 30-40 minute queue!) they didn't have any in stock. They've ordered one in though, and should be here Tuesday-ish.

Fingers crossed the next one can get more than two hours of screen time!

First charge....95% to dead. Amazed at the battery life so far. We'll see where this goes from here...
[Galaxy Note 4 General] joelteixeira:
If the "bad results" are around 3h or 4th SoT I'm really happy since that's already a big jump to me, on my Moto G (2013) I get around 2h SoT and usually is enough for my daily usage. Thanks for all your demonstrations, I'm really satisfied with the overall results. I don't expect to disable nothing neither I need more than 3h on my standards.
[Galaxy Note 4 General] an_xda:
Not as great as I would hope for. I have turned off location reporting so hopefully the next charge will be a little better. I also have to be fair in assuming there were a bit of background processes and a bit of Spotify/bluetooth streaming as well!
[Galaxy Note 4 General] Grimmlocks:
I had battery drain issue too, even with the 30mb update. Did a factory reset and now battery behavior is much better. Still has to settle down.
[Galaxy Note 4 General] krishman:
Look forward to this kind of battery life, currently on my S4 I'm lucky to squeeze out 3hrs SOT with Location Services off :crying:

[Galaxy Note 4 General] jeccross:
Wonder if anyone can help me, Just got my note 4, left home this morning at 7 am on 100% battery, now on 67% 2 and a half hours late. Fair enough I did so some video streaming etc on the commute but it says 47% of my usage is android system, so something appears to be eating it in the background.

Any idea how I can find out what it is and fix it?

Thanks
[Galaxy Note 4 General] koppee1:
2nd day w the note 4...

In the morning, I had power saving off, auto lte/3g, brightness at -4 (anything higher i find too bright strangely..), nova launcher, lock screen wallpaper change on, static wallpaper,

disabled the following apps (not rooted, did this through applications manager):

blurbcheckout

flipboard

galaxy apps

google play books, movies, music, newstand, search, plus, hangouts

hp print service

live weather

messenger (fb)

samsung account

samsung billing

samsung galaxy app/widget

samsung galaxy life

samsung print service

samsung push service

In the afternoon, I decided to turn on power saver with only cpu performance ticked.

not bad...i came from an LG G3....where I could rarely get 4 hrs...on average, i only got a screen time of about 3 hrs or so...too much clash of clans haha.
[Galaxy Note 4 General] an_xda:
I slept with the phone @ 100% at 12:30am

Woke up @ 85% from idle + background processes... That is horrible!
[Galaxy Note 4 General] clintonroche:
OK, not picking, but why do people not just charge the phone at night while you are sleeping? That is what I always do.

You are not going to hurt the battery, Li-Ion batteries are best when they stay charged, you don't need to run them down to zero. In fact many studies say that is the worst thing you can do for your battery life.
[Galaxy Note 4 General] ShadowFlare:
The best thing about Removable Battery is that, after a year or two and you feel the battery is losing charge faster than it use to.... you can just buy a new battery!

Besides, maybe he was just testing the standby time over night. I would too. But 15% lost while sleeping really is terrible. My Z3 Compact loses 2% in my 7 hour sleep, not rooted or disabled any app/service other than Location Reporting. But I leave Location Services running. I'll be getting my Note 4 tomorrow, let's see if mine can do worse.
[Galaxy Note 4 General] clintonroche:
Yea, I get it and I was not trying to be an ass. I agree it is terrible, but is it the first day? Maybe updates and such are running. If you have had the phone for a while, maybe do a restart. Or if you are going to leave it on overnight then close all apps before you hit the hay.

I don't even have mine yet, but I am going to kill the battery today when it comes in...LOL :p
[Galaxy Note 4 General] an_xda:
From my experience it is because battery calibration can be screwed up. My older HTC One X and iPhone 5 prematurely dies @ 15-20% remaining because I always kept it plugged in at night.

Also, this gives me a good indicator of how idle drain is during the night when background processes are the slowest. 15% over 7 hours of idle? Horrible, my iPhone only lost 2% and HTC probably drops 5-6%.

This is not my first day having the phone but if a 15% drop over 7 hours of idle time in the middle of the night does not concern you... Then getting abysmal battery performance will satisfy your needs since you can quick charge it every 8 hours.
[Galaxy Note 4 General] quadlt:
So I'm back after a week of use with finally rooted, amplified, greenified, frozen apps etc and still getting 4 hrs of SoT is a surprise. Minimal use with rare gaming, SMSing and some evening surfing. Te-rri-ble. :(
[Galaxy Note 4 General] Dan1909:
Seems there's a few strange issues like this going around, I'm still struggling to beat 2 hours SoT over the course of a single day!

But I'll be picking up a replacement handset tomorrow, let's see if that's any better!
[Galaxy Note 4 General] quadlt:
Quote me back or PM if you could, really interested if this is faulty device or software stuff.
[Galaxy Note 4 General] KarimSalloum:
3rd day now. 80% HSPA+, 20% WiFi. 4h30' SoT on average. No heavy usage, no games, just Whatsapp, and other social media apps. Location on battery saving. Kinda disappointed. The QHD isn't helping. Hoping that a custom ROM in due time will help.
[Galaxy Note 4 General] findingwaldo:
Hey are you more on lte or h+? I play a lot of clash too and I want to see battery life with heavy gaming usage. Looks like you're getting pretty good life with some clashing lol
[Galaxy Note 4 General] JippleStar:
I will update with more screenshots later when my phone is almost dead. Not really sure why I only took one screenshot, but whatevs d:

Model: SD (Verizon)

Brightness: Whatever setting it comes with

Disabled Apps: Amazon Kindle, Music; Audible; Blurb; DT; Google Play Books, Movies&TV, Music; Google+; Message +; NFL; Slacker

Apparently I did not take an SS of the screen on-time, but I'm pretty sure it was over 5 hours? Could be wrong though, haha
[Galaxy Note 4 General] t1337dude:
Great battery life so far. Charged my battery to 93% at midnight last night, it's 5:00 PM today and I'm at 78%, and that's after 8 hours of streaming music and about 30 minutes of texting and selecting songs n such.
[Galaxy Note 4 General] an_xda:
24% remaining with 2h 40m SOT... LTE for all 18h 46m of uptime on this charge... :(

Edit - now phone is dead! Last 5% was in forced power saver mode which probably gave me a little more screen time.
[Galaxy Note 4 General] Zanr Zij:
Show me detail of Android System and Google Services
[Galaxy Note 4 General] 2ndammendment:
FALSE. Lithium ion batteries do NOT like to be keep at high voltage and it can be much worse than cycling the battery. Charging to only 4.1v or 90% can double the service life of lithium ion cells., 4.0v or 80% quadruples the service life. They don't like to be deep discharged either. Their ideal operating range is somewhere between 85% and 30% depending on chemistry. However, they should be take down to 0% every once in awhile to recalibrate the fuel guage. Keeping your phone plugged in overnight is NOT a wise practice. It's like leaving your automobiles engine redlining in garage while your not using it. Look at EV's if you require more proof, they limit their charge voltage to around 4.0v to dramatically extend the service life of their vehicles batteries.

Furthermore it shouldn't be necessary to plug in your phone overnight. If your device is running properly then you shouldn't lose more than 5% per 8hrs. As posted by me I got 2.7 days with 5hrs of screen on time, no power saving and all stock.
[Galaxy Note 4 General] cathain:
Had my note 4 nearly 2 weeks now and the screenshots below are pretty much as good as it has been for me, loads of stuff disabled including GPS, bluetooth, shealth. I've been on wifi most of the time too. I'm returning it for a new one tomorrow so will hopefully see a difference?
[Galaxy Note 4 General] markyboy81:
I'm pretty sure that it's perfectly safe to leave the phone charging overnight, otherwise we'd have to closely monitor it charging and remove it from the charger as soon as it reached 100%,which is very impractical.

I've charged my phones for years overnight and never had any adverse results.

As for the question why would you need to charge it overnight, this comes down to convenience. The time when my phone generally needs charging is at the end of the day, and the best time to charge it is when I'm not using it,ie I'm asleep.

If this was an issue we would have far more complaints about batteries degrading prematurely.
[Galaxy Note 4 General] 2ndammendment:
When did I ever say or imply that it wasn't safe to leave your phone plugged in overnight? No one is talking about safety we are talking about service life/longevity. Whether you noticed the effect of cell degradation or not doesn't invalidate the fact that it happens. Lithium ion batteries do not like high voltages and it will reduce the service life of a cell, period.

Say what you will but it doesn't change scientific fact. Batteries degrade. Some degrade faster than others depending on charging habits, temperature etc. Some consumers notice degradation, some don't. At the end of 2 years seeing a 30% reduction in rated capacity is not unusual for mobile devices. Do what you will but you're trading convenience for cell life. Personally I don't find it inconvenient to plug my phone in after work for an hour top up charge, but your usage pattern may differ from mine.
[Galaxy Note 4 General] Vangelis13:
Batteries take as much juice as they need, after that they sleep better than us. Perfectly safe to charge as long as you want / need.
[Galaxy Note 4 General] markyboy81:
Fair enough then I suppose that charging it every night may affect the longevity of the battery but I can't say I've ever noticed it.

I'd still rather charge overnight and then possibly need to replace the battery sooner (although most likely I'll be on to the next phone by then:) )
[Galaxy Note 4 General] 2ndammendment:
I will reiterate myself. I am

not discussing safety

. I am discussing cell life/longevity.

Yes. Lithium ion batteries have circuitry which monitors several parameters such as cell voltage and temperature. Yes, they do stop charging once they hit their desired voltage limit. However, just because a battery does not spontaneously combust does not mean it's happy. Furthermore when at 100% the cells will undergo mini charge cycles at 4.2+ voltages which is quite undesirable. I will say it again, lithium ion batteries do not like being keep at high voltages. High voltages such as those experience at full charge cause cell degradation. The only reason batteries in consumer electronics are allowed to reach their maximum cell voltage is because the industry desires maximum run time over cell longevity. For every reduction of 0.1v a lithium ion battery will be able to preform double the cycles during its service life. Manufacture could make batteries in cellphones last 2x as long by limiting the cell voltage to 4.1v but doing so would reduce runtime by 10% so they don't. Again, look at EV power supplies, many EVs use lithium ion chemistries and almost all of them are limited to extend cell life, they could push them to 4.2v instead of 4.0v and gain 20% more range but doing so would make the cell reach the end of its service life 4x sooner.
[Galaxy Note 4 General] markyboy81:
Sorry, I think there's been some misunderstanding here. When I talked about 'safe to leave charging overnight' I wasn't talking about the risk of anything blowing up, what I actually meant was that I didn't believe it was bad for the battery or would damage the battery.

[Galaxy Note 4 General] JippleStar:
Model: SD (Verizon)

Brightness: Whatever setting it comes with

Disabled Apps: Amazon Kindle, Music; Audible; Blurb; DT; Google Play Books, Movies&TV, Music; Google+; Message +; NFL; Slacker

Always on: WiFi; 4G; S-Voice && Air Swipe Wake up;

That is all I can remember for now, if I missed anything, well, phone's dead so I assume it's too late :D

Also, I feel like I got better life without most of those extra functions and features enabled (obviously) so I might disable them again later.

Edit:

Air gestures (or whatever) seems to keep my Note 4 constantly awake. Although I cannot confirm that this is what kept my phone awake, the air unlock function was the only change I made on my phone the other night.
[Galaxy Note 4 General] an_xda:
Will do it in today's dump. Can definitely say Location Services are off as well as a few Google play apps being disabled.

Maybe it is not on WiFi as much as you think... I know when I am on LTE, there is idle drain of about 10-15% per ~7 hours with default background processes. That might be it.
[Galaxy Note 4 General] ShadowFlare:
Ideally there should only be 2% idle drain on 4G in 7 hours. I'm not one to say with my N910C that just arrived, gulps battery like no tomorrow. Haven't charged it, just put battery in, started with 64% charge, and downloaded my apps. Location Service is ON but Location Reporting is OFF, No Power Saving.
[Galaxy Note 4 General] koppee1:
i was more on h+...not LTE....
[Galaxy Note 4 General] JippleStar:
Wow your phone is like always on O_O;;

Also, does it save battery life if you Turn on location services while leaving Reporting Off?
[Galaxy Note 4 General] ShadowFlare:
In my experiece since Note 3, doing this prevents my phone from apps randomly waking it up to check location, while Location Services is still ON. Probably saves even more battery with Location Services OFF as well.
[Galaxy Note 4 General] JippleStar:
oo that's cool :3 think I'll try that out
[Galaxy Note 4 General] 2ndammendment:
"Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery. Choosing a lower voltage threshold, or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Since the consumer market promotes maximum runtime, these chargers go for maximum capacity rather than extended service life."

[Galaxy Note 4 General] markyboy81:
Hmmm interesting. Is this saying that by fully charging you damage the battery and reduce the longevity, ie it retains less capacity more quickly?

But by not charging fully you still end up with less capacity so the outcome is more or less the same for both?

I'd be more bothered about battery care if the Note 4 had a non user replaceable battery and/or I saw a noticeable deterioration in charging batteries like this fully on overnight charges.

But as it is I've always done this and must have charged the battery in all phones I've owned at least 300 times with no noticeable loss of capacity, so I won't worry about this too much.

Convenience is more important to me.
[Galaxy Note 4 General] clintonroche:
Sorry 2ndamendment that came out rude and I did not intend that...LOL.

I was at a stop light typing and thought I saved it for later but I must have sent it. In the battery university website somewhere it also says that you shouldn't full discharge the battery either. And periodic (throughout the day) bump charging the battery or partial charges typically do not harm Li-Ion like the older rechargeable battery types. I agree 20-80% is the sweet spot for maintaining Li-Ion batteries.

As someone else said replacement batteries are not that expensive so pretty much you can do whatever is most convenient for you.

Cheers!!
[Galaxy Note 4 General] 2ndammendment:
Unfortunately it get rather complicated. If you charge to 4.1v or 90% you do have lower capacity so you do have to do more cycles but at 4.1v you gain 2x the cycle life so the slight increase in charge cycles from having a lower starting capacity is overshadowed by the massive gain of 2x longer cycle life.

Hmm yesterday i managed over 5hr sot but now its gone down to 3/4 again... draining while asleep again... so depressing :(

I rooted to try and find the problem and now bettery battery stats says batteryinfo service could not be contacted whenbi try and look at wakelocks
[Galaxy Note 4 General] donkon:
These are my stats as of today starting from 100% on first chargu since getting the phone. I have gereenified installed with DU Battery. I didn't root the phone yetIve been mostly setting my phone up, Installing stuffand browsing the net. The battery is bad though . The phone is amazing. My model is the N91OF
[Galaxy Note 4 General] michsu:
Take a look at how much your Android System is draining... it is draining 27% of the time.. that seems to be a lot.. I managed to get it down to about 17% for now about a hour SOT.. but I will run up my screen time to match yours and then see what happens.. as of this moment, I have 2 hours 20 minutes, and screen on time at 1h 38m and at 83% battery left...
[Galaxy Note 4 General] michsu:
Here is mine so far... your battery seems to be pretty good at getting 5 hours SOT and still having 30% left.. I may not even meet that.. I'm running a Crunchyroll (anime) video test and just let it play through now to get on screen time.. will report back with update later..

I think the display is a big battery killer.. I'm on auto brightness now, but I should try if setting manually at 25% or 50% is better.. I played with DU Battery, Greenify, Memory Booster Full and a few other apps that close all/kill all; Currently I am running only DU Battery and Memory Booster Full.. Greenify is good, but you need to hibernate all the apps (and a lot of system services) too to get a good boost; Also, by doing that, it auto-hibernates all the time with the screen popping in and out, so basically it is 'awake' all the time.. (since I tend to check in on the phone every few minutes due to email and such); It shuts down the notifications too and won't receive any email notifications (I use Floatify and Mini Text and a few other widgets that display info, if you hibernate them, they won't work then next time you open the screen); This is the best combo I can come up with so far for the battery life without affecting main services like email/gmail/facebook + notifications + s voice + s pen stuff + GPS too (Maps);
