My battery life seems off. Any ideas what I can do to fix this? The only thing I have frozen right now is Samsung Link because it was always #2 on battery stats with the Android System as #1. I didn't have these such issues on my S3.

I founf this application to. Might give it a try. https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app

WOOT! I just took this screenshot 10 minutes ago. Looks like I'll be getting 6-7 hours screen time. 4 hours screen on time and 40% battery life left.

This is with Clean ROM 1.0, Nova launcher stock kernel, Beautiful widgets, glasklart go apex icon theme and just volume mods

Android System --> BBS relation

How long have you had your phone for? I just got mine on Wednesday, and I was having some concerning issues with battery life as well, which lead me to get BetterBatteryStats to investigate further. Android System was using the most, as in your case, and it didn't seem to last long.

The first night (Wednesday) I let my phone fully discharge to dead and charged to 100%, and repeated two more times (3 total empties to full, as I heard this may be good for the batteries initial 'burn in') in the consecutive days.

The attached screens are my current battery stats, and you will notice, that in my case, Android System just seems to be very basic backgrounds running, mostly related to Deep Sleep, which as far as I'm able to research, is what we want. As for the battery drain, I would look at BBS yourself, and see if it may be wakelocks and whatnot. Try doing some battery cycles to calibrate if it is new I suppose? :)

Dunno if this helps, but I also thought I'd toss this out there for others who may see similar things on their new shiny S4's.

No problem with battery life here. This is on stock rooted, auto brightness, and some notification/status bar mods. Took it off charger around 7am this morning and it's 12:35am now. 4g 75% of the day and Wifi 25%.
[Verizon Samsung Galaxy S 4] najaboy:
You heard wrong. The singular thing that accomplished was to shorten your battery's lifespan. Lithium polymer batteries need no cycling.
[Verizon Samsung Galaxy S 4] madsquabbles:
batteries life can be shortened b/c of the heat you expose them to when charging, but they never really fully discharge (they won't recharge if they fully die). the full cycle doesn't necessarily help battery life, but it does allow for a more accurate battery calibration.
[Verizon Samsung Galaxy S 4] dansan382:
i know it had a lot of idle but im still very impressed. i was using it during the day and left it overnight without charging.
[Verizon Samsung Galaxy S 4] suzi002:
re

Lots of positive answers!
[Verizon Samsung Galaxy S 4] Idioblast:
So I didn't do too much to my battery by doing those cycles right? Because I had heard just that, that it helps calibration, especially since it was a new device outta the box. Still running stock and tw though... Ironing out the first 14 days before root to make sure the device as a whole is good before flashing and whatnot.

Even now, overnight, im still seeing great life!
[Verizon Samsung Galaxy S 4] dstreng:
got ridiculous battery life with clean rom and faux 003m. on faux 005m right now and will report back when it settles in a bit
[Verizon Samsung Galaxy S 4] xXJay_RXx:
Okay what exactly do people do for battery life? Those who are getting over a day and like 5-6hrs of on screen time. Do you guys use Facebook or twitter? Do you guys have sync off? I have Bluetooth GPS and all that fancy motion/sensor features that Samsung includes off. I don't get no where near what you guys get. I'll get about 12hrs with 3-4 on screen time
[Verizon Samsung Galaxy S 4] majeiks:
I'm in that boat, too. I'm averaging 2.5 hours screen on time and 12 hours battery life. Some screenshots of recent activity:

[Verizon Samsung Galaxy S 4] Eric214:
Well I'm a battery NUT CASE lol. I do whatever I can to get crazy battery life. I don't use Facebook or Twitter. I turn all auto sync off but for work email and set that for syncing once per hour. I freeze most things i don't use in the apps list especially from VZW or Samsung unless it needs it for the features and normal phone functions. I go into data usage and other than Google services, email, media and a few other things i see whats using background data and disable background data in each app, not the general restrict background data for everything.

Also, make sure you are updated to the play store 4.1.10 and NOT on 4.1.6 which the phone came with. 4.1.6 has known bugs for causing battery drain in Location services.
[Verizon Samsung Galaxy S 4] igotgame:
I posted my great battery life on the previous page.

I have the following primary things on:

- Sync for email

- Sync Google Account

- Twitter notifications

- Smart Stay

- Auto brightness

- Air View

I have the following important things off:

- GPS

- Location Services

- Sync for anything not mentioned above

- Air Gesture

- Bluetooth

- NFC

That's basically my average setup. Get great battery life as seen from my post on the previous page.

Thanks I'll give this a whirl

How many minutes of on screen time does it take for your battery to go down 1%? Like an estimate of how many minutes
[Verizon Samsung Galaxy S 4] najaboy:
Straight out of the box, cycling is completely unnecessary. The charge and discharge flags are set already. When the need actually arises, only one cycle is needed to "calibrate" the flags and need only be done a handful of times during the battery's lifespan.

Remember that lithium based batteries are only capable of a finite number of charge/discharge cycles and that depth of discharge affects this exponentially.

If you'd like a good primer on batteries, I'd check out www.batteryuniversity.com
[Verizon Samsung Galaxy S 4] DarkMenace:
I haven't frozen anything yet. Here's some of my stats. I think I will freeze Samsung Link eventually if it keeps up with the CPU usage.
[Verizon Samsung Galaxy S 4] Idioblast:
Oh ok, thank you for the understanding. Yeah, after the matter of the third full discharge, I had actually found the HOWTO for Lithium-based batteries listed here on XDA. Now I try to charge it around 40%, as the stats and links he had showed that its their 'favorite' spot to be charged at, to keep the heat down, and to have a nice cycle, and kicked myself for doing three, but I havent seen any noticeable difference at all, as per my last screenshot. ;)
[Verizon Samsung Galaxy S 4] igotgame:
On average...I probably get 5-5.5 hours of screen on time. You can see my stats from yesterday a few posts earlier where I had 4 hours 45mins and 1 hour of phone calls and that was primarily on 4g. Today for example, I'm at 2 hours screen on time and 67% battery. That's on pace for about 6 hours of screen on time (realistically I'll probably get 5.5 hours)

I forgot I also have some some apps frozen using titanium backup to. Stuff I don't use. Here are screenshots of those (the last couple of apps frozen and not shown are Verizon and Yahoo apps):
[Verizon Samsung Galaxy S 4] th3drow:
today I'm at 50% with 12 hours 43 minutes and 1 hour 33 minute screen time. Mostly on not so great signal, so 24 hours with 3 hours screen time isn't to bad, this is on the latest hyperdrive.

Hello all,

What is the average battery for this phone?

What battery app helps find this out... or what do you recommend.

Thanks

also are you guys using a certain rom and kernal?
[Verizon Samsung Galaxy S 4] chrisjm00:
Maybe the play store was what was causing my drain. I was on 4.1.6 and was getting almost 70% usage from Google Services. Screen was at 24% or so with two and a half hours.
[Verizon Samsung Galaxy S 4] midnightzak:
Loving the battery life on this!

HyperBeastMode Activated! (Hyperdrive ROM)

Faux Kernel on his suggested settings

Screen Brightness 100% (not auto)

Power Saving Off

AirView / SmartStay both On

1.89ghz max / 162mhz min

-50mV undervolt

intellidemand governor

gpu ondemand governor

fiops scheduler

You can tell by the screens that it's kind of odd usage, but the battery lasts and lasts!

Going to turn brightness to auto, power saving on, airview off, and smartstay off, and see what happens...
[Verizon Samsung Galaxy S 4] Eric214:
[MENTION=3057515]chris....[/MENTION] Hopefully that with help you out a lot by updating to 4.1.10

also since I don't use maps much I freeze it in TiBu until I need it. Maps was causing huge wakelocks and another reason Android OS was high in the battery stats.
[Verizon Samsung Galaxy S 4] igotgame:
Just an update to those that were asking earlier about my battery life. 3 hours screen on at 51%...so good pace today.

[Verizon Samsung Galaxy S 4] dontcallmejames:
mine kinda sucks. my phone gets bad signal in my office so it's just draining constantly trying to find a signal. i have wifi there, but it's still rough compared to my previous phone. i switched from a iphone on ATT to a galaxy s4 on verizon. certain roms seem to improve my battery life. running synergy now and it seems much better.
[Verizon Samsung Galaxy S 4] chrisjm00:
I'm not sure what is going on with my battery. Even after updating the Play Store to the newest version, I'm still getting sky high Google Services drain. My screen time is only nine minutes today, and in two hours I'm sitting under 80%. Signal isn't perfect at my desk, but it still isn't bad. Google Services has taken up 85% of my battery over the last two hours. The included packages are Google Services Framework, Google Account Manager, Network Location, Google Play Services, and Google Contacts Sync. I have all sync disabled so I'm not sure what is going on.
[Verizon Samsung Galaxy S 4] D Stave:
With my use, I basically just have to charge it every night when I go to bed. I'm coming from a razr maxx, so this is a bit strange to me but I'm doing fine with it. I was expecting the battery to get a bit better going to an AOSP rom as they are much smaller, but so far it seems similar.
[Verizon Samsung Galaxy S 4] metalunna:
I think I have my Wifi Idle battery drain issue nailed down.

I have an old WRT54G (tomato) on my network that I use for legacy devices.

Turns out it had "Allow Multicast" checked in "Advanced"

Once I unchecked it, I went from 3-5% idle drain per hour to less than 1%.

Never would have thought that was causing me almost 2 weeks of torment. Now I can actually use my darn phone instead of tweaking a setting and then letting it sit for an hour.

Hope this helps someone else out....

P.S...This setting only seemed to affect my wife's S3 and my S4...All other wifi devices on my LAN were not affected (that I could tell).
[Verizon Samsung Galaxy S 4] mwm523:
Mine seems pretty good so far. Charging once a day, and using pretty heavily. Flashing ROMs, Nandroid backups, etc. So far so good!
[Verizon Samsung Galaxy S 4] Eric214:
[MENTION=2986205]chris...[/MENTION] Make sure you have any syncs off in maps and GNow. I disable my maps when i don't need them by freezing in TiBu.
[Verizon Samsung Galaxy S 4] jpen:
I just froze my maps after seeing it on for almost an hour and a half and I didnt use it once! No idea why. I was using Facebook but I have the location thing turned off.
[Verizon Samsung Galaxy S 4] chrisjm00:
I haven't even seen maps show up on my usage, and all syncs have been disabled for a while. I did a clean install too. I may download a different ROM tonight and give it a whirl.

What do you mean by hyperbeastmode? I'm using hyper and just curious.

Also where did you get the faux kernel?

I thought hyper already had governors set up? You using an app like setcpu to set your own?
[Verizon Samsung Galaxy S 4] trebb:
I think he'st just calling his setup "hyperbeastmode" as a joke.

He installed Faux kernel, and then it looks like he used the Faux app to change the governor and other settings. Hyper, stock, has its own settings.
[Verizon Samsung Galaxy S 4] gsxcorey:
I see faux123 in the app store. You just purchase that and the app will let you control settings, but just curious does it come with and flash the kernel or? I know it's a newb question so sorry.
[Verizon Samsung Galaxy S 4] Coderedpl:
You can download from forums and flash in recovery or buy the app, download through there and then flash in recovery
[Verizon Samsung Galaxy S 4] gsxcorey:
I'm nervous about flashing the kernal as I found the thread about it and see several with issues. My question. When I do a TWRP backup does it backup the kernal? So that if i flashed the kernal and had issues can i just boot into recovery and restore my backup and then it I'll be back where I was? Not sure if restoring through TWRP will write over the kernal or if the kernal is included in the backup/restore process?
[Verizon Samsung Galaxy S 4] DarkMenace:
There's a Kernel file you can download to gain the stock kernel back. You flash it via Odin in the PDA slot.

[Verizon Samsung Galaxy S 4] jadecamaro:
I have found disabling sync and mobile data when my screen is off has greatly slowed the steady drain on my phone. I know this is a commonly battery saving strategy but on my thunderbolt it took forever to switch the radios or wifi on and off. Pleased that the galaxy is very smooth toggling these functions rapidly.

What apps did you remove with TB? I don't know if you have a full list or not but that would be awesome! I was able to remove about .16gb on my own, but I know I messed up and removed some things. I was no longer able to use some of the camera modes, and I didn't have voice control anymore.

[Verizon Samsung Galaxy S 4] xs11e:
Adequate.

I rate my S4 (unlocked, rooted, CyanogenMod June 165th Nightly) as adequate. I had to swap batteries in my S3 (also unlocked, rooted, CyanogenMod nightlys) to get through a day, if I were going out for the evening I'd swap batteries before leaving home because I knew the stock wouldn't get me past 9 or 10 PM when the phone came off the charger at 7 AM.

I do not need to swap or carry a spare battery with the S4 so it's OK, it's long enough battery life for me and, as always, YMMV!

half a day
[Verizon Samsung Galaxy S 4] 299792458:
Wow so interesting finding to report:

My 'Android System' has been tearing through my battery. I have started leaving wifi enabled, so my phone now connects to wifi when I am at home and at work. 'Android System' is no longer the biggest consumer, screen is.

Overall battery life approaching 50% improvement. Without wifi, severe 'Android System' drain was occurring even when I was in continuous full bar LTE coverage.

I suspected possibly location services or something wanting to use my radio and continuously failing, but I have enabled location services (gps, cellular, and wifi) now since leaving wifi always enabled and no drain is evident.

So enabling wifi definitely made a huge difference for me. I don't really know if it is only due to using less LTE radio. I really think it may be due to a process trying to do something when radio is on and wifi is not.

Edit: forgot to mention I didnt have this android system draining the first few weeks I had the phone. I never used wifi before and had normal battery stats (screen pretty much always used the most). Then the past 2 weeks or so 'Android System' became a battery hog. And now it goes away with wifi on. :what:
[Verizon Samsung Galaxy S 4] AvengedZombie:
Seems as though my battery doesn't last as long since the latest OTA update. Could be my usage has increased a little though. Still unsure.
[Verizon Samsung Galaxy S 4] joefrog1996:
I could go 2 1/2 days if I left 4G off. About 18 hours if it's left on. If only I could just use 3G. It would be the best of both worlds considering I need to be connected all the time.
[Verizon Samsung Galaxy S 4] shuddle13:
Noticed the same here, but haven't been able to pinpoint if it is the update, or the new phone. I switched from the 16GB to the 32GB, around the same time the update rolled out. Been watching what uses the battery to kill it and hopefully improve it back to what it uses to be. Next step if I can't do it myself will be to install and run a battery saver app.
[Verizon Samsung Galaxy S 4] jasondec72:

Came from the Samsung Fascinate. Battery life is easily 2x with Moderate usage. Get 32 hours easily.
[Verizon Samsung Galaxy S 4] ManVsBeer:
Sorry no screen shots or stats, but real world usage I'm very pleased.

Stock aside from the Apex launcher and a theme.

Unplugging at 7am going all day with about an hour streaming Pandora at the gym with bluetooth headphones and I'm good to about 9am the next day. I work in an office and have a short commute so I'm not really a heavy user but since it's a new toy I'm constantly fiddling with it still at this point. The battery meets my requirements perfectly. Those rare occasions when I'm listening to a lot of music or burning the GPS I'm pretty confident I'll get by. I'm very happy with the low end battery life; from 30% to empty takes a long time.

Coming from the Galaxy Nexus where I was lucky to make it to 5pm with light use on custom ROM's and kernals; this is a huge improvement. It's still not where my iPhone 5 is at a day and a half to two days but it's close enough.

Cheers,
