OK, I took a screenshot this morning. I'll caveat that I had to tether to my laptop last night for a bit so I have a a charge spike. I can't say for how long...I was a bit stressed and didn't think of logging time. So results are now skewed. I was on email & Skype a lot after that and a bit over night. As I'm posting I'm at 27% remaining and SOT of 4hours 31minutes.

In response to beastofexmoor:

I'm using one sim currently....I really only use 2 when I'm on travel. SIMs are bit different compared the original zenfone. My zenfone 6 had SIM slots that could both be set up for data (3G 42Mbps type), however only one could be handle data at any given time. It was nice as I never had to remove my home carrier SIM from it's slot so no fear of damaging the sim slot of dropping my SIM at any airport mobile counter. You just had to direct the phone to use SIM slot 1 or 2 for data...genius in my opinion.

For the zenfone 2 only SIM slot 1 handles data (3G/LTE(4G)). Slot is 2G only. I guess they had to cut a bit of cost somewhere.

Thanks for the screenshots! battery life looks pretty good. Any chance you could run some benchmarks for us like geekbench/antutu/GFXbench3.0?

Might be getting the one with the Z3580 soon

As the title states, I might be getting the one with the Z3580 soon. couple of days soon (hopefully tomorrow though). I'm not sure if any confusion might've developed after reading an article on BGR. I bought the 1080p model with 4GB of RAM but 32GB of storage. According to the BGR article, that model doesn't exist and only comes with the Z3560. If it is the model that I want I will post some usage data on that. There isn't much info on this phone so I'll be a guinea pig and post what I find.
[ZenFone 2 General] Bl00dRunzC0ld:
All the reading I've done says it's the Z3580.
[ZenFone 2 General] canuck-e:
Just wanted to post my final battery stats....forgot to get the a screenshot of my SOT but it was 5H39M when my phone hit 9% and nearly 2 days of run time. I'm more then happy with this performance. Z3560@1.8GHZ, 1080P screen.
[ZenFone 2 General] canuck-e:
Once the battery was depleted, I charged using an Aukey Quick Charger (QC2.00 charger) just to see if the phone is compatible with some of the Qualcomm specs.

11:19AM ......9%

12:02PM.....69%

12:19PM......82%

1:03PM.......99% had to head off to a meeting so I couldn't get it 100%

Screen grabs attached.

[Nexus 7 (2013) Q&A] noahvt:
Hi XDA users,

I'm having some more issues with my N7 2013 I use my tablet mostly for watching youtube in the evening but my battery is like 20% most of the time so I plug it in and start watching youtube. But I've noticed that after half an hour the battery was 10%, the battery seems to be draining whilst plugged in! It happens every now and then sometimes it charges just fine, I've tried different chargers and cables but it doesn't affect it. The battery seems to be dropping 1 to 2% every 5 minutes and it'll eventually turn off and turn back on right after when it turns back on the loop continues, it works for another 10 minutes then it shuts off again! Of course if I leave it alone it will charge just fine but it's still weird that it discharges even though it's plugged in while in use. Even listening to music causes it to drain. I'm using a 5v @ 2amp charger so I assume that's not the problem. (I've also tried a bunch of 1 amp chargers but it has the same effect) I'm running screw'd android (5.0.2) and the only things that seem to be draining the battery are Youtube(22%) and the screen(18%) the rest is all 1 or 2%! Yes I've tried flashing ROM's and the issue does go away but it comes back after like a week or so.

Does anyone know what the problem is?

thanks,

noahvt
[Nexus 7 (2013) Q&A] fury683:
You're likely drawing more power than you're putting in. I believe the stock charger charges at 1500 or 1700 mAh, which should work to charge it while you're using it.

If you are using charger from another device charges more slowly like 500mAh or even 1000mAh, it may not be able to keep up.
[Nexus 7 (2013) Q&A] noahvt:
I'm using a 2000mAh asus charger from my old TF300T and if I'm pulling more current than that charger can supply I don't know what the thing is doing
[Nexus 7 (2013) Q&A] averagegeek:
I think your device has some issues with battery.If you are still in warranty period,get it back to stock condition & contact the support
[Nexus 7 (2013) Q&A] BSnapp:
My wife has the same problem.. She has to turn her screen off, in order for the battery to charge.. If she doesn't, it keeps running the battery down.. Try turning the screen off, and check it after 15 minutes. You may be pleasantly surprised.. Hope this helps you out..
[Galaxy Note 4 General] shinasurada:
I have noticed that the WiFi on my note 4 drains 30% of the phones battery on average and this exceeds the battery drain of the screen even with an SOT of 4 hours.

this is easily overlooked because the stock battery monitor does not show how much battery WiFi consumes. It only shows if its on or not. However the GSAM app will show it.

My phone is an n910c.

Smart network switch and WiFi scanning are both off. Phone is connected to a stable WiFi but when in the WiFi menu it shows that its scanning ever few seconds. this might be normal.

Attached are screenshots of battery consumption of WiFi and my settings.

Please post here if you have the same issue.
[Galaxy Note 4 General] tomashaker4e:
I find the GSAM app very incorrect, just look at the SOT, my said max screen on time per charge like 5 hours while i was at my 6th, so automatically was wrong.
[Galaxy Note 4 General] darekz:
Scanning is off for lication services but you have notification for open networks which requires frequent scanning and you have keep alive during sleep.
[Galaxy Note 4 General] Kanon25:
If you have set your Location service in "high accuracy" or "power saving" modes, then you have also permitted use of Google's location service, which scans wi-fi and/or mobile networks at all times - including when you have supposedly turned your wi-fi "off".
[Galaxy Note 4 General] henklbr:
Have you tried a reset of your phone and see if the problem is still there?
[Galaxy Note 4 General] shinasurada:
Is that an n910c?
[Galaxy Note 4 General] henklbr:
As stated in my signature: SM-N910F
[Galaxy Note 4 General] shinasurada:
Just got confirmation from another n910c owner that the WiFi can account for up to 53% 53% of the battery consumption when turned on. From what I see on the battery thread, the n910f even when connected over WiFi for 40 hours only takes less than 3%.

If we figure this out we will definitely be seeing Snapdragon like battery life.
[Galaxy Note 4 General] DEdwards22:
I'm trying to combat this myself. On another note, how do you have access to WiFi Timer? I don't have that as an option. N910V 4.4.4
[Galaxy Note 4 General] Infinitesimus:
That would explain so much. The phone still lasts me a day but I was always surprised by the WiFi battery stat in GSAM and thought it might just be reporting it wrong. I hope this issue (if it is indeed one) is addressed in the 5.0 ROM magically ;_;
[Galaxy Note 4 General] Ausboy 2011:
N910U wifi is 3% for me
[Galaxy Note 4 General] shinasurada:
Thanks for the datapoint ausboy.

Seems like n910c is the only variant affected.

Samsung should take note, this is why the battery life on the n910u is much better even though both are exynos.

I'm on 4g now and the battery life on 4g is way better than with wifI on. I've tried different routers and it doesn't make too much of a difference.
[Galaxy Note 4 General] golfinggino:
Not sure why you guys are getting such poor battery life I am getting consistently 7-8 hours screen on time with location on Bluetooth on connected to my gear s sync on pushing 5 email accounts wfi about 75%and when I lte I don't really have a good signal most of the time - I also have a 10,000 mah zero lemon battery but I get such good battery life with the stock battery it is never really needed the extra time
[Galaxy Note 4 General] shinasurada:
And do you have the n910f or n910c?
[Galaxy Note 4 General] snowblind2142:
There is a exposed based app called amplify which you can chance service scan times for pretty much everything. Highly reccomend.
[Galaxy Note 4 General] DEdwards22:
I actually meant the feature that let's you set up specific times for WiFi to be turned on automatically. I've got a third party app for that currently and would prefer to have the Samsung version.
[Galaxy Note 4 General] shinasurada:
Can anyone with the n910c try other firmwares and report back if the n910c still experiences the same problems?

So far two users with the Malaysian firmare experience this wifI battery drain issue. I'm not sure if the others are on the same fw.
[Galaxy Note 4 General] azuldio:
Hi, I have been noticing that I have not had that great a battery life as with other users of the note 4. Was searching all this while for an explanation until I came across this thread. I am also using a SM-N910C with XSG firmware that is UAE and am also facing this drain. I installed GSAM as you mentioned and can see that Wifi is accounting for up to 27% for me. I will post the screenshots once I run through and entire charge cycle.

Had earlier contacted Samsung online support about the same but they simply asked to go to a service center and get the battery checked. But I guess that this is a particular issue to only the N910C.

I don't think it would change your battery life at all and you can always uninstall it but it is your choice to make.

Thanks for providing input though.
[Galaxy Note 4 General] rszalski:
Hi guys!

I have the same variant of Note 4 (N910C Europe release) and I'm also experiencing battery issues while on WiFi. WiFi stays on and keeps my phone awake. During night (7-8h) it can eat as much as 35%-40% of fully charged battery. One more think to check for you is if you have Air Wake Up (hover-over-phone-to-wake-up) enabled. Using BetterBatteryStats app I noticed it held around 93% of all Wakelocks. Nonetheless, the WiFi is still the main offender. I hope that Samsung will release and update soon. Otherwise, a custom rom (Cyanogen, once it gets out) might be the only option.

Todo:

I'll try to post a full dump of BetterBatteryStats once I get a good dataset (full day with WiFi on, full day with only LTE Data on),

Locastion Based Services might also be involved, I have currently changed it to GPS only (maybe it wont query WiFi/BT as much?).

Below are my Advanced WiFi settings (in Polish, but the layout is the same I believe).
[Galaxy Note 4 General] zurkx:
simple way of getting far better battery life. first, reset to factory settings. then put a 256 x 144 black png as your background scaled up. then do :

settings- display screen - mode - basic.

enable auto adjust screen tone.

smart stay enable.

daydream off

touch light key duration 1.5s

screen timeout 15s

brightness -5 auto

settings - developer options - windows animation scale off. transition scale off duration scale off. show all ANRs.

(you will have to enable dev options - click on build number in about device 7 times)

your battery life will magically improve. :)
[Galaxy Note 4 General] Infinitesimus:
The N910U uses an Intel radio so that might be why. It seems the issue might be Samsung's radio (?) in the C? Hopefully it is something that can be fixed with a firmware update :/. I don't want to root and throw on a new kernel temporarily
[Galaxy Note 4 General] DarthJe5us:
So is there any fix to this bug or do we just wait for them to hopefully fix it?
[Galaxy Note 4 General] Toss3:
Mine only eats about 8% (4% after I have my screen on for a bit)and I have a 910c (4G eats a lot more). Could be a router/signal/software issue rather than a hardware issue on the 910c.
[Galaxy Note 4 General] Jonathan-H:
Never recommend resetting to factory settings. This makes zero difference for battery life or stability and are you going to help them reset up their phones and recover potential lost files and pictures etc?

Smart stay and auto brightness will both degrade battery life, basic setting for screen won't make a blind bit of difference. Black background not make a blind bit of difference either unless you stare at your homescreen for ten hours a day.

As for wifi. Wifi does not keep my phone awake. Only rogue processes.
[Galaxy Note 4 General] zurkx:
do yo even know how amoled works ? black pixels consume no power. smart stay keeps the display on while looking at it off otherwise. auto brightness keeps the phone at enough brightness to see it without burning battery power in all conditions. basic setting reduces power from the pixels displayed by making them neutraly bright instead of vivid. factory reset ensures all settings are defaults.
[Galaxy Note 4 General] shinobu91:
It's true black pixels consume no power, but do you often use your phone on home screen where it is black, or in apps?

Do you know how the smart stay keeps the display on while looking at it? It uses front camera to track your eye, so or course it consumes more battery. Same with auto brightness, every few second the phone will look the surrounding light and adjust to it, so more sensor is on = more battery drain, if you want more battery, use lowest brightness that still comfortable manually.

Factory reset is not needed, I'm sure all the people doesnt want the settings to default, and after factory reset, people will change the settings and apps again to their taste so it has no effect.
[Galaxy Note 4 General] zurkx:
most of the time. when you put your phone down without locking it its just sitting there burning power until the display timeout.

sure the sensors consume power but much less than keeping the brightness high or screen on. how many times are you going to adjust screen brightness until you get tired of it ? how short is your display timeout going to be ? mine is 15 seconds because the screen stays off when i dont look at it and it stays on when i do.
[Galaxy Note 4 General] Vangelis13:
Bad signal / coverage. The biggest hog of them all. You can save as much as you want with tricks, bad coverage will overrule all of them..
[Galaxy Note 4 General] shinasurada:
That is true. But in this scenario the WiFi destroys the battery life.
[Galaxy Note 4 General] Vangelis13:
That is indeed a bug, or so it seems at least. In general though, bad reception is a killer. :thumbup:
[Galaxy Note 4 General] shinasurada:
Any n910c owners willing to install GSAM app and provide more data points on this WiFi issue?

Thanks
[Galaxy Note 4 General] pierrekid:
These battery postings mean nothing. I can easily get 6-7-8 hours of onscreen time too if I run on battery saver mode all day. Or even 10-15 hours on super battery saver mode. Also depends on screen brightness, app usage etc... So for people trying to figure out how they are getting that kind of battery life, there is your answer. If you want crazy battery life.

Screen bright less than 20% and run power saver all day. You will get at least 7-8 hours if not more.
[Galaxy Note 4 General] shinasurada:
well I'm just trying to see the WiFi usage relative to screen usage. It should be no more than 5% of battery usage for WiFi regardless of what you do.
[Galaxy Note 4 General] neograniceni:
N910C here. In over two days since the last charging according to GSAM WiFi used 31%. 56:33:38 active time. Screen used 20%, apps 30%. Battery still on 20%. I keep WiFi enabled but it turns off during sleep. However location service in power saving mode (WiFi only) is turned on all the time. So I guess this may be the reason why the wifi active time is 56:33:38 and usage at 31%. I'll charge the battery today and will disable location service just to see how WiFi behaves thereafter.
[Galaxy Note 4 General] bean12147:
I have tried this but it doesn't make any difference. Even know the Wifi doesn't turn off , although I have configured it in Wifi advanced settings. What is definite is that WiFi is to blame. Does anyone have any solution?

[Galaxy Note 4 General] shinasurada:
That's pretty saddening... now do all note 4s use the same WiFi chip? the exynos versions might use the Broadcom bcm4358 according to my research.

The Qualcomm Snapdragon s805 seems to have its own integrated WiFi solution but I don't know if they used the Broadcom instead.
[Galaxy Note 4 General] bean12147:
For what its worth mine was OK, no WIFI battery drain and without any new app installation or anything it started acting up. Smells like a software bug, something which is corroborated by the Keep WIFI on during sleep sleep setting in WIFI->Advanced. For me at least this setting doesn't work.
[Galaxy Note 4 General] somemadcaaant:
Try removing any third party apps you don't use much like Facebook, Twitter and linkedin, email apps with exchange services etc. You'll get much better battery life ><

Also might try setting up better Wi-Fi scan interval http://xdaforums.com/showthread.php?t=2503997

Battery life not an issue with the T-Mobile Note 4. I get over two days easily with moderate to normal use. *Define normal, :silly:
[Galaxy Note 4 General] shinasurada:
The Snapdragon is unaffected by this bug
[Galaxy Note 4 General] NoteMaxx:
I tested my 910C since 1.5 days ago but wifi seems ok at around 2 to 5% when it's left on. A large part of the time, it's not actually connected (but intentionally left on) to any network but I don't see any significant difference with it connected.

Only time I saw a significant change was when I accessed play store for about 6 to 8 minutes, downloaded only about 54MB of stuff, the drain spiked up to 17%! I've taken some screenshots but don't think it's useful to post since I did not take right before and after accessing the play store, didn't expect it to drain the battery that much.

Other details :

Whatsapp and line for social stuff

Facebook disabled

Mobile data turned off

No battery saver app nor in any power saving mode

Mail on manual sync

Phone's wifi left on even when there's no ap to connect to, actual connection time approx. 3 to 5hrs.

When connected to ap/hotspot signal strength is usually at full bars, poor reception coincidentally when I used it to access the playstore due to the distance from the hotspot.

I can post some ss if anyone wants just doubt if it's useful.
[Galaxy Note 4 General] Infinitesimus:
wakelocks

Update:

Been digging into this issue some more on my N910C. I don't want to root the device so I used the PC version of wakelock detector to try to pinpoint the cause. Under kernel wakelocks, I noticed that besides the catch-all powermanager wakelock, wlan_rx_wakelock was the highest, this generally shouldn't be the case but it did tell me that something on the network was broadcasting often enough to wake my device up several times.

For the home network, Wireshark on the desktop revealed that it was sending quite a number of outgoing messages, I decided to disable the IPV6 helper service and WMP Network Sharing Service on the desktop to see if that helped. Put the PC to sleep shortly after and noticed that it woke up ( !!). put it to sleep again, it woke itself up after about 15 minutes. This doesn't always happen so it was a little bit weird. Hoped on and realized that Intel Smart Connect Technology had both "Keep Data Fresh" and "Remote Wake" enabled so I turned those off (I might enable remote wake again in the future to test). Anyway, the drain has significantly improved and I'm at ~8% WiFi use now (instead of 50% as per my previous screenshot) and screen is at 32%.

If you're investigating wakelocks, this xda post is a good read.

At this point, I no longer think the problem is with the N910C but more likely something on our respective wireless networks gone wild. I can't do much about my work network though since I don't have control over that. Check for printers and other devices (Dropbox Lan Sync was the cause for some other people in the GNex days) sending a lot of messages.

If you have a spare router around, you can simply put your phone on a different network to see if that affects the wakelock.

I'll report with what I find during the week when I'm back at work.

tl;dr: It is likely something on your network is sending very frequent messages and keeps waking up your phone. Best bet might be to sniff the network and find out what machine (via the IP address) is doing that.
[Galaxy Note 4 General] Artoriuz:
My 910C arrived this last week and so far I can safely use the phone for 2 days with normal usage...

It's here for 8 hours at wifi and cellular with 85% battery left (50 minutes of screen on), this phone is amazing.

If I remmeber correctly, I got 6 hours SOT on the first charge, setting everything up and playing A LOT with the device.

I tried multiple routers with the same result...

When not connected, I noticed the WiFi doesn't drain much battery when on.
