[Galaxy Note 3 General] EddieN:
This is very true. Back on my old GNex i used to have crazy wifi wakelocks and I couldn't for the life of me figure it out. I never figured it out, actually. But I am positive it is one of the two PC's on my network that are broadcasting packets across the network, waking my phone up. I haven't had time to extensively test the wifi wakelock in the environment i've previously encountered it in to see if it still applies, but since I haven't changed anything regarding any of the two computers involved on that network, I'm positive I will have the same wifi wakelock issue when I get back and test. Is there a way (besides using Shark) to see what programs are broadcasting packets across the network?

But to get back on topic, I am experiencing battery drain connected to ONE router with ONE AP. I am in an apartment building with several other routers nearby, though. Maybe they are broadcasting packets somehow that the kernel is interpreting and keeping the phone awake? However it seems as though the Android OS bug keeps coming back for everyone no matter what, even in airplane mode.
[Galaxy Note 3 General] PlutoDelic:
Wifi has evolved a lot the last decade, not just by technology standards but into integration as well. carriers use them as small cells, we'll see them more often in the future (malls, stadiums, etc), and HS2.0 adds to make it a bit more seamless, they call it offload, taking your data needs through small wifi cells rather then the macro cells (3g, 4g), hence offload.

my point is that they would have never invested in that if the wifi chips inside consumer products were not efficient enough, so nearby APs shouldnt be a problem at all. But im still puzzled for what would one need the waking up process through wifi?

If Wifi is the general bugger, then somebody throw an eye on the Passport service, thats the consumer name for HS 2.0 services.

PS, tested AP Isolation on my sh!tty WRT120N, no difference unfortuantely.

Will there be a future update from Sammy or will we get Kitkat directly
[Galaxy Note 3 General] mongoose3800:
Just a follow up. I have still had no battery drain since avoiding connecting to wifi networks that use multiple APs. Now, i only connect to wifi networks where i know there is only one AP. Before I stumbled across this the drain and Android os wake lock was bad, really bad, after I had connected to large wifi networks - I just hadn't put two and two together. This is more than coincidence - my testing is sound and replicable. And, this week I have been in remote areas with weak to no 3g signal and the battery life has still been fantastic and no wake locks so that sort of rules that out - Sure there is a little increase in battery usage but nothing dramatic, something to be expected and certainly not something to complain about. I have seen many claims to fix battery drain but these are just fine tuning and not addressing the major drain caused by Android OS wake locks. Clearly, there must be an issue with the wifi software driver in MJ7/MK2 and I hope Samsung/Google are aware of it. The annoying thing is getting Samsung to acknowledge the issue and take feedback.
[Galaxy Note 3 General] EddieN:
I get wake locks even if I manually turn wifi off and only use data. When I use wifi i am connected to only one AP and I still get wake locks. The wake locks aren't apps, they are "Powermanager.wakelocks" and "Powermanager.Display" and show up as "Android OS" in battery settings.

I am still not convinced avoiding multiple AP wifi networks is the one-for-all solution for everyone.

However, I have put "wifi on during sleep" to "never," yet my phone slept maybe 50% yesterday but wifi was on 100% of the time. Why is this? Shouldn't it have turned off the 50% that the phone was sleeping?

Something is weird with the wifi module..
[Galaxy Note 3 General] mongoose3800:
Have you ruled out any other wifi connections? Have you tried rebooting if you have connected to another wifi network? Have you tried forgetting all wifi networks? Reboot after forgetting all networks. Then give it a couple of days with out connecting to any wifi network - just a test to confirm it is wifi related. I tend to think setting wifi to never on during sleep makes no difference - I had previously tried it too. Once the drain starts the only way to stop it is to reboot.
[Galaxy Note 3 General] EddieN:
Yes, just last week I was on another Wifi AP about ~300km away (totally different environment) and I still had the same wake locks. I have rebooted when connecting to another wifi network. I have tried forgetting all wifi networks i have connected to, and reconnecting to them. I have also rebooted once forgetting networks. During this time I also took the liberty of doing the normal rounds of disabling location services etc. before rebooting, but nevertheless i did reboot once forgetting the network. All networks I have been connected to have been single-AP wifi networks.

I have not let it sit for a few days without connecting to any wifi networks. That's the only thing I haven't tried. However I have let it go a whole day with wifi turned off (and only data enabled), but the same wakelocks persisted. For me it's always "Powermanage.Display" and "Powermanager.Wakelocks" no matter how long i just let my phone sit around with the screen turned off. I have it right beside me so I always have visual access to the screen in case the phone wakes up on its own, but it never has. I guess I could try turning wifi off for a few days and seeing how it fares, but I doubt I will see any difference (wake lock wise).

I'm thinking something is strange with the wifi module anyway. Surely wifi should turn off by itself once the phone sleeps, right? Like I said in my other post, my phone slept maybe 50-60% of the time on a 14 hour day. That means Wifi should have been on 40-50% of that time, and off 50-60% since the phone technically should have been sleeping. Yet I can see in the battery settings menu that wifi is a solid green bar all across the 14 hours.
[Galaxy Note 3 General] mongoose3800:
Well that's interesting. At least in both cases we know it's Wi Fi. I wonder if it's something if it comes down to the type of connection. Eg 2.4 vs 5ghz
[Galaxy Note 3 General] EddieN:
It could be. Both networks I have been connected to have been 2.4GHz Wireless-N capable routers. I just find it odd that a lot of things don't add up when looking at awake times in Settings -> Battery and comparing it to kernel/partial wakelocks in BBS/WLD/CPU Spy. All of the times seem to be roughly in the same ballpark, but they never add up to correspond to each other. Surely there must be information missing in this regard.
[Galaxy Note 3 General] duffmannr3:
I can confirm the WiFi issue on my N9005 but there's another one.

1. Wifi: I experienced this at my university, where we have good Wifi coverage on the whole campus. They use Radius for logging in. After using Wifi for about 15min, I had these wakelocks, which didn't stop until I rebooted the phone. Since I knew this, I haven't been using Wifi there any more. But: In the meantime, I did a factory reset and got this little stability update. A few days ago, I gave it a try again. Used Wifi at university for ~25min and hat no issues. Maybe it's gone, I will test again some day.

2. I had an app called "gentle alarm". On my GNexus, which I used before my Note 3, I also had wakelocks, but couldn't figure out what it was, since wakelock detector, better battery stats etc. didn't show more than PowermanagerService.Wakelocks/Display. So I got my new Note 3 and still had these Wakelocks - I did much Monitoring and: It was this tiny alarm app. Very funny: After having excluded every other possibility and having the wakelocks active I uninstalled the app on my Note 3 and it instantly rebooted!

Great battery life now.

Hope this helps someone. BTW: The Wifi issue on larger networks seems to be a problem not only on Samsung phones, many people are experiencing this (e.g. found similar reports for Nexus 5...).
[Galaxy Note 3 General] EddieN:
Thanks for your input. Is the wifi issue you are talking about the fact that it doesnt turn off when having "wifi on during sleep -> never" set? Or the multiple-AP issue the thread is talking about?

What stability update is it that you have received? What country are you in and what firmware are you using? Did you get this stability update while on MJ7/MK2 firmware? I haven't received any notification for a stability update OTA...

Thanks for the Powermanager.Display/Wakelock issue. I guess I will have to sift through my apps and uninstall each, one by one, to see if the wakelocks disappear. If not, there is some other issue :(
[Galaxy Note 3 General] duffmannr3:
It's the issue about "multiple" APs, but I don't think that it is about the number of APs. What I have read is that there is so much traffic on those big networks, e.g. broadcasts from other devices. I don't know how it should be with your problem that wifi doesn't turn off - can you see if it's reconnecting after some standby time? If yes, then wifi is turned off during sleep, but is just not shown in statistics.

I'm currently on MJ7/MK2. My device is unbranded and I'm living in Germany. It came on 26th of December and was about 30MB or so.

It's definitely worth a try! There was absolutely no hint that pointed to this one app. I started with having a look at the battery statistics ~every 30min after a fresh reboot. After a few days it was clear that it only could be the alarm app, battery draining started only in the morning.
[Galaxy Note 3 General] amirzubair:
The only cause of my battery drainage was during sleep coz of mobile data. When I left my note idle for hour about 6 to 8% battery drops. But when I left my note idle on airplane mode not a 1% drops during 5 to 6 hours.
[Galaxy Note 3 General] EddieN:
I just want to go ahead and bump this thread again since I've had a chance to again visit the environment I was in (~300km away) when I made my last post, claiming there was no difference.

Well, turns out there is a difference. A big one. It could be several factors though, and PowerManager.Display and PowerManager.Wakelocks are still the largest contributing wakelocks when "Android OS" skyrockets and keeps the phone from sleeping. It must have something to do with either devices connected to the network you are connected to, or wifi networks interfering with the network you are connected to, or something with the router you are connected to etc. because it is not normal.

As soon as I connected myself to the single-AP WiFi-network, my battery drain was up to 6 %/hr which is a LOT. In my normal environment, my battery drain is about 1-1.5 %/hr, so still some drain but much much smaller. The normal environment I usually am in is also a single-AP WiFi network.

So to conclude, both environments are single-AP WiFi networks with a lot of networks around (apartment buildings, 10+ networks in range). The only difference between the two environments is the amount of devices (TV's, computers, phones etc.) connected to the AP at once. It is therefore difficult to say what it is that is causing the drain, but I'm pretty certain it's something with the WiFi module.

I've had wifi wakelocks before, but not this time around even though it seems to incorporate wifi. Not really sure what to do, just putting it out there.

Has kitkat solved this problem?

[Samsung Gear 2] malnsk:
Better camera(more megapixels, better sensor). no explanation needed here. Led Flash for night photography. IR Blaster. I love the Wach On app. Gesture customization. i would love to have gestures customizable so for instance i could swype up from the clock screen and run any app desired. Ringtone and notification customization. and app specific notification, so i would immediately know which app has a notification, before i even read it. Wi-fi direct for faster data transer and maybe web browsing. And of course a better battery life. one day autonomy is unnaceptable. two days or at least three would be best. so that we can use it for a full day or two no problem
[Samsung Gear 2] lilstevie:
This. The 3 stock tones for each are horrible.

I would also like to see it opened up for 3rd party dev rather than the closed development we have now.

WiFi would also be a plus. Doesn't necessarily need to be able to connect to AP's, I would be happy if it could do WiFi Direct to the paired device for access to the internet, twitter quickview takes a little while to load over BT, and images and videos could be transferred much quickly, or even in the case of video streamed directly to the devices storage to remove the time constraints.

Bigger mmc, would be nice for 8 or 16gb storage, this of course goes well with the third party dev, but also for pictures and videos.

Lastly a slightly better battery, or more power efficient SoC.
[Samsung Gear 2] amsguitarist:
Larger wrap around display.

Longer battery life

Persistent clock face

Perhaps another model with a low profile round face?

Option for a metal band.

Universal android support
[Samsung Gear 2] ronfurro:
Inductive charging capability

AM/FM radio

GPS radio

IR blaster would be great!

Battery Saver mode: Throttle CPU, Screen, Radios

Move all components into the case, so normal straps can be used.

Someone needs to made a good bio-sensor health app. specific to the Gear so exercise and sleep can be monitored and compiled.
[Samsung Gear 2] teegunn:
I agree with all of this but would add:

Onboard GPS

Blue tooth capability to use BT headphones

Keep all components in Watch itself (nothing in the band)

More powerful processor

Bigger battery

Stand alone media player (even tho we can sideload one now I suppose)

Persistant clock face! (this one seems like a no-brainer can't believe the Gear can't do that now)

Ditch the charging cradle - give us a micro usb port.

Mostly, I want more stand alone options with more power (the watch can get slow IMO) and it's own WIFI capabilities (BT wifi is slow as molasses). Although I realize most people don't want a mini version of their phone and the Gear was not meant to be used like that, it would be nice to have it do those things if a person wants. And for me it would make it one cool James Bond watch even more than it is now!
[Samsung Gear 2] Jeshter2000:
We know that all of these options people want. The watch itselfs will get a lot bigger.

I think it is awesome this way. Maybe only a FrontFacing Cam. Nothing more I want.

As the watch size itself is more important to me.
[Samsung Gear 2] pigglett:
Adding all those as Jeshter2000 states will increase its size ...It will need a bigger battery to run 1/2 of those features hence bigger watch
[Samsung Gear 2] @home:
To work with all android devices.

I'd like it as an update on the one I have now. I don't want to have to buy V2.
[Samsung Gear 2] malnsk:
this isn't neccesary IMO. you can connect the BT headphones to your phone. why would you connect your phone with the gear and than gear with BT headphones(unless the stand alone media player gets implented).

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] mingolianbeef:
Let me make my disclaimer:

"I am not a noob! I have been consistently active in Android (development and flashing) since the MyTouch 3G Slide days. I understand partition differences, I understand (from experience) that jumping in head first and flashing roms meant for other devices can brick your phone, and I understand that the first thing most people (including myself) think is N00B alert, but this isn't the case."

Now, I have done nothing but flash Sprint ROMs on the device. However, when I noticed that there was a sim slot in my phone the first thing I thought was "What the heck?" Then, some major googling revealed that it needs it for the 4G LTE, but it can also be used on international carriers. THEN, I found a guide posted by a dude that showed how you could set up Domestic GSM carrier sims to be compatible with this phone (And fully functional). SO! My question is, if it walks like a duck and quacks like a duck, can it run an international GS4 rom? I'm asking because I would love to see what Ubuntu OS is like.

Thanks in advance!

I don't understand why you flashed PA 4.0 beta, when you want 4.4? Also, the gapps file you used should only work with 4.4. I have no clue how it would have worked for PA 4.0?

And for future purposes, if it makes it any easier, try TWRP instead of CWM - it's a lot more user friendly. In terms of the insufficient storage, I'm having a feeling that you either haven't wiped your SD card before flashing, or something has gone wrong and the system is not detecting the SD card...
