I guess my next question is what is the how is the screen time being used? Web browsing or other? Most of the time I even use my phone it's for data related things like web browsing or apps that access data somehow. I too have all the fancy things turned off except quick glance, I never turn BT on, GPS is off, location services is off aside from the attached screenshot. The other screenshot is my usage today so far. I don't use the phone nearly as much as you guys, but the little bit I do use it just seems like you still get way better life than I do. I unplugged it 12 hours ago and still have 63% battery left, but only about 1.5 hours of screen time. Although I used GPS navigation today for about 35 minutes, so that chewed it up a little faster.

I didn't root it yet because I've been thinking there isn't a "best way" to do it yet, but I've been disabling apps as I find out I don't use them. Some of them aren't possible to disable in stock form though so I'd need to freeze them I guess. Other than that, does disabling effectively do the same thing as freezing?
[Verizon Samsung Galaxy S 4] najaboy:
For the exact same reasons that some people still tout wiping battery stats or say batteries need to be primed... a varying combination of logical fallacy and ignorance.

If an informative link is what you seek, www.batteryuniversity.com is a good starting point. And, since wiping battery stats has been mentioned a couple times, the Google Plus page of Dianne Hackborn contains the definitive debunking of that bit of misinformation.

Browsing, games, youtube, etc.

Using Ktoonsez kernel with their recommended settings. Also getting 12700 quadrant score (yea, I know, means nothing).

Coming from a Galaxy Nexus, this is epic for me.
[Verizon Samsung Galaxy S 4] jayochs:
holy balls... so I'm at 4 hours screen on right now, 14 hours off charger... and 20 percent left. all on stock kernel on clean rom. damn. lol but this was wifi all day though

I'm digging my battery life... first day on a full charge... 14hrs total with 5.30hrs screen on time. On stock un rooted rom as well... no screen shots sorry. Lots of texting, web browsing, you tube viewing and playing a few games. Wow! Oh and that was at 5% left.
[Verizon Samsung Galaxy S 4] metalunna:
OK..I've been holding off on posting but I've finally gone over the deep end:

Verizon Model

STOCK - No ROOT

I'm noticing about 2-3% per hour "IDLE" battery drain when connected to my Wifi. (based onGSAM - and stock battery info)

When I turn off wifi, and stay on 4G, i lose approx 1% per hour

Biggest drain is Kernel (Android OS)

I'm seeing large keep awake times (almost half of the idle time)

The largest is the infamous wlan_rx_wake

I have several wifi AP's in the house (G and N2.4 and N5ghz). No matter which AP im connected to, I still get Idle drain

WRT54G (tomato) - G

Actiontec Rev I - G

ASUS - RT-N66U - N2.4 and N5ghz _ (Primary connection)

I have tried many things such as:

Set Wifi policy to "Never" and "Always " - The difference is "slightly" better with "Never"

modifying the Beacon and DTIM invervals (currently at a modified Beacon = 50 and DTIM 9)

Set static IP on phone

Disable WMM

No widgets

no location services

Factory reset (no Play apps installed)

No sync

Disabled as many apps as I could. From what I can tell, the phone is pretty clean as far as processes and services)

I'm coming from a Bionic with an extended battery and currently that thing gets loses less than 1% when on Wifi

I have several other Wifi devices online (Ipads, Nexus 7, various other droid devices) and no others experience the drain like this

My wife's S3 loses about 2% per hour, but she's got a few things running and I'm not allowed to touch it :)

Anyone else getting 2-3% per hour Idle drain?

I just want to be able to enjoy this thing..It's gotten to the point that I dont even use it because I have to keep it ide for an hour at a time just to get some stats.

Thanks.
[Verizon Samsung Galaxy S 4] GreatDayChap:
I'm pushing around 24 hours each charge with fairly heavy use, though that's with the CyanogenMod nightly flashed. I hadn't actually used the phone on stock TW for long enough to know how well that would last for me. I'd imagine it would be in the same area though.
[Verizon Samsung Galaxy S 4] breakstaff:
my battery life rockss ! use it for whole day :)
[Verizon Samsung Galaxy S 4] mattamous:
On 4g the whole time with moderate usage.
[Verizon Samsung Galaxy S 4] ktklein72:
On average for the three days I've had it I'm only getting about 12hrs with moderate use. I'm stock and not rooted although I did install Nova Launcher, Unity Launcher and Swiftkey but I don't think any of those actually cause a significant drain. I believe screen is set to auto and I have to see what other options there are I can fiddle with to get some more efficiency. 12hrs is a bit disappointing to me since my older Droid X2 got about a day using the same apps the same amount of time.
[Verizon Samsung Galaxy S 4] ThugosaurusRex:
I've noticed the wifi drain too
[Verizon Samsung Galaxy S 4] berfles:
Don't know about any wifi drain, overnight my S4 discharges at a rate of less than 2%/hour, somewhere around 1.6-1.7% I believe.
[Verizon Samsung Galaxy S 4] metalunna:
This morning I read a post that mentioned the WLAN_RX issue may be related to windows 7 PC's on the LAN.

http://xdaforums.com/showpost.php?p=25876666&postcount=3

Now, I know that IPv6 can cause issues on some networks (I work in IT and have had projects to completely disable IPv6 on some servers via registry --not just uncheck it). However, I utilize the Media Player Sharing and the Shell Service is helpful to me. However, for science, I just shut down my Windows 7 machine and let my phone Idle...

I did see a bit of a difference...Slight.

Then I happened to click on a stray link that mentioned to turn off any Wifi Printers. OK...thats easy.. I have an HP OfficeJet 4500 - Pure Wireless printer..I turned off the wireless.....

After almost 5 hours..I only have 4% drain...that includes having my windows 7 PC powered off...

I just powered the PC back on (and disbaled IP6 and the IP helper service since I dont use it)..Ill see how it goes.
[Verizon Samsung Galaxy S 4] mach1man:
Im not to familiar with wake locks but is mine to high or right in the middle. My phone is connected to wifi almost all day.
[Verizon Samsung Galaxy S 4] chrismyu:
people are getting some crazy battery life!
[Verizon Samsung Galaxy S 4] ktklein72:
I'm not one of those people. I'm on wifi maybe 65% of the day and I'm only getting 10-12 hours of estimated usage and I'm not using the phone constantly either.

This was today with 1 episode of game of thrones (55m min) plus YouTube and Web surfing.

I put in Clean ROM 2 days ago and is been ridiculous with battery. Also on idle I'm getting less then .5% per hour battery drain.

Also I noticed some of you talking about the wifi battery drain thing on the unrooted stock ROMs. I think it might have to do with the ongoing wifi in the notification drawer. You get that damn "scanning for network" thing where the scan interval is WAY to often. That is causing some wakelocks I'm betting.
[Verizon Samsung Galaxy S 4] najaboy:
The persistent notification definitely has a correlation to battery drain. Those that are stock and have removed it have seen a corresponding decrease in use by Android OS. It needs to be borne in mind that it's not merely a notification that is there “just because.” That notification represents a process that is running on the foreground, consuming power in and of itself, even when WiFi is off.
[Verizon Samsung Galaxy S 4] jayochs:
wat.
[Verizon Samsung Galaxy S 4] mach1man:
What notification are you talking about?

Im having some high android os % and dont know why.
[Verizon Samsung Galaxy S 4] najaboy:
The persistent WiFi notification.
[Verizon Samsung Galaxy S 4] ktklein72:
I'll read up on rooting the VZW GS4 and the removal of the persistent notification and afterwards report back on how my batt life is affected.
[Verizon Samsung Galaxy S 4] jonw757:
My batter life has been great. I am able to go all day without charging which I havent been able to do in a long time. Coming from a Galaxy Nexus with extended battery, this is still way better.
[Verizon Samsung Galaxy S 4] xXJay_RXx:
So how much screen time are you guys (and ladies probably lol) averaging per 10%? I'm averaging about 30 minutes per 10%. I don't know my battery isn't last as long as everyone's on here. I'm on LTE most of the time also since my home internet has a data cap n I'm only using the WiFi for the laptops, 360 and PS3s. Can someone chip in?
[Verizon Samsung Galaxy S 4] shanimal92:
This is running Hyper Drive Rom with Faux's kernel underclocked to 1.7, intellidemand governor, and with eco mode activated. The whole time the screen was on the brightness was max, and I was streaming Hulu Plus, Netflix, YouTube, and Hubi. No 4g, just WiFi and Bluetooth on. I am in a bbasement with spotty coverage; I don't now of that makes the battery life worse even though I'm using WiFi instead of data.
[Verizon Samsung Galaxy S 4] xXJay_RXx:
I'm also not familiar with Wake locks. Can someone explain this to me? It seems to be taking the most battery
[Verizon Samsung Galaxy S 4] berfles:
Guess I could have gotten 4.5 hours of screen time last night.
[Verizon Samsung Galaxy S 4] Eric214:
Depending on the ROM you're using and what restrictions you have on apps/processes as in background data disabled and what bloat you have frozen you should be seeing from 4-6 hours of screen time. I think I can squeak out about 6 hours of screen time on my phone with clean rom and all syncs on manual other then my work email account (syncs once an hour). I have maps frozen unless i need it, and only wifi/mobile networks on for location stuff. I also don't use auto brightness, i have that off and screen at about 25-30% unless i need it brighter outside.
[Verizon Samsung Galaxy S 4] metalunna:
I rooted this morning and removed the wifi drop down notification-- no change in wlan_rx wake

I then installed shark and saw that I was getting some traffic from my western digital live players...and massive traffic from my Onkyo receiver.

I disconnected them from the network and traffic stopped but I was still getting wake locks (almost half of idle time)

I just disconnected my asus 66u and I am now running from my old linksys wrt54g. About 30 minutes in and no Crazy WLAN locks.

I could swear I was getting drain while connected to the linksys during my testing a few days ago, but maybe I was just chasing the wrong lock at the time..

I'll report back if the locks stay suppressed while off the Asus
[Verizon Samsung Galaxy S 4] NiteQwill:
For those not using autobrightness. I suggest Velis Auto Brightness. It handles brightness way better than the system does, allows you to see your screen without constantly adjusting (low light & direct sunlight) and conserves battery.

@ xXJay_RXx I see your wakelocks are up and you have teh ebay app. That damn app was cause like over 1000 wakelocks in just a coupe hours on my GS4. You're reporting 2.2% on ebay abay app but your system wakelocks are WAY high at 19%+ you might want to look at that ebay app. Just maybe some help since it was an issue for me last week

[Verizon Samsung Galaxy S 4] Reginalb124:
Mine is far better than my Bionic was for battery life. My Bionic was great, except when using wifi tether and Groove IP, those two apps in tandem just demolished my battery life. But they don't have nearly the negative impact on the S4. I am getting great battery life, quite pleased.
[Verizon Samsung Galaxy S 4] xXJay_RXx:
How are you guys getting 5+ hours of onscreen time and 12+ hours on the battery? I can't even make it past 8 hours on the battery. What do you guys do? :confused:
[Verizon Samsung Galaxy S 4] rednoved:
Mine has been that good from the factory with the stock rom. I think the real question is what are you doing or have done to get 8 hours?
[Verizon Samsung Galaxy S 4] xXJay_RXx:
I would be listening to mostly music while at work and no more than 2 hours of on screen time from browsing Facebook, Instagram, twitter, xda and some browsing. I'm on a new ROM now so I'll see how the battery is now. I work tonight so I'll see how it works out this time
[Verizon Samsung Galaxy S 4] kvswim:
Does anyone know if these have NFC?

http://www.amazon.com/dp/B00BCJWYMU/ref=cm_sw_r_an_am_ap_am_us?ie=UTF8

In my opinion, they are a reputable brand but I see no indication whether they have NFC or if they're just a regular battery.
[Verizon Samsung Galaxy S 4] berfles:
I can't wrap my head around how people use phones that much with the screen on... Guess I'm just a different user, but I get home from work and I'm lucky if I have a total of 30 minutes of screen time, and by the time I go to bed it's at like 2 hours of screen time. I know the battery lasts 4+ hours of screen time but I guess I just don't use it that much.

I unplug it from the charger at 7:20am and by the time I go to bed around 1am the next morning it's at 50-60% battery.
[Verizon Samsung Galaxy S 4] Evocm7:
I don't let anything sync, power saver mode on, auto brightness, set Max background tasks to 2 in Dev settings, turn off all notifications from social apps. It just works for me for some reason.

I'll try that max background tasks thing. I never seen that before.

Okay half way through the night and here's what I got. Good? Bad? I listened to music from PowerAMP for a good 3 hours. The on screen time is mostly from Facebook and Instagram

Now what does worry me is these wake locks that keep saying media server. I did a Google search on that and I've read that it might have to do with files in my SD card? Is that true?

Also my battery goes down 1% every 2-4 or 5 minutes its turned on. Is that normal for everyone else? I have the brightness to maybe 10% with auto brightness off. Thanks for any help
[Verizon Samsung Galaxy S 4] D4nyal:
Woah! That's awesome battery life. Mine kinda sucks because I don't have it rooted so these at&t applications are there still and drains battery.

My battery runs out the next day, the same time I fully charged so meaning to say, only 24 hours battery life.
[Verizon Samsung Galaxy S 4] Diversion:
Latest results.. Wifi on, medium LTE, low brightness (sometimes auto), syncing for everything (facebook, gmail, work, etc.) on, GPS off, Powersave ON

Needless to say, I only get these results due to not using very processor or data intensive things.. This was mostly web browsing, reading articles, texting a lot, phone calls.. Rarely did much else. Very basic usage.

CleanRom Lite with Faux M kernel
[Verizon Samsung Galaxy S 4] suptt14:
Stoked about the battery life! Beans 2 Faux Kernel ftw. Also froze/removed a lot of other "bloat". Mainly WiFi, auto brightness, push sync on 3 mail accounts, not really doing much to conserve I guess but with the bloat gone and Beans with Faux kernel it just works

Looks like I have a reason to root and use Clean Rom now. It never was 50-60% android stuff before.. but the last few days it has been. Guess there isn't really a reason for me not to root and custom rom now.
[Verizon Samsung Galaxy S 4] suptt14:
Yeah its definitely worth it! I used CleanRom for a few days and it was really solid. Everything worked great plus good battery life I just get bored. Switched to Beans a couple days ago with Faux Kernel and have best battery life yet with stability of stock. Everything works no complaints at all

Why do you guys care how the battery does at night? It's on the charger anyway. And if you forget to charge it at night, you charge it in your car on the way to work then charge it at your desk at work for a bit and boom.
[Verizon Samsung Galaxy S 4] mutelight:
Because it is a good way to determine how the idle drain is and if apps are causing wakelocks.

This drain coming into play in the countless other scenarios that fall outside of the two you listed.

[Verizon Samsung Galaxy S 4] BzBz:
held off on commenting about battery life until i settled down into a regular usage pattern. with a little over two weeks of having the phone i can say the battery life is very good. i'm getting "extended" battery performance out of the stock battery. that's compared to my galaxy nexus with the 3800mah hump. with the s4 2600mah i have no worries about making it through a 12 hour day and still having 50% or more left. that's with almost 2hr screen on time and 30 mins worth of calls. gps/maps might even come into play for a little while. i'm very pleased with what samsung has accomplished in regards to battery life given the performance and screen size.
