Android system usage on battery? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Mine settles around 7-15% sometimes a little over if I go heavy usage, just curious what others usage is around. I kinda feel like its sucking battery, but I can't really tell... Running Sky ICs 4.2 update 9

7%. Trust me though, thats fine. If u really want to check what's eating your battery check for wake locks using the betterbatterystats app, as well as CPUSpy, to make sure you phone is entering deep sleep

Battery usage.

I am on dfgas' Heinz 57 ROM which i love. However, i go to see what's using my battery since it drains pretty quickly, it says my display is using 98% anything i can do to not use so much?

Well the obvious answer would be to not turn your screen on so much. But a couple realistic options are - turn down the brightness (turn off auto-adjust). Personally I leave mine at the lowest setting and the only time I feel like I need it brighter is occasionally outdoors. Also, the app Juice Defender has been amazing for me. Basically what it does is turn off all data whenever the screen is off. You can adjust things to your liking as well. I went from having to charge my phone at some point during the day to having 20 percent or more left when I go to bed.
If you kept the OTB kernel that comes with that rom, you can also mess around with undervolting in Voltage Control. I keep the screen at the lowest brightness setting and have a decent undervolt, and I usually have 20-30% battery remaining at the end of the day if I unplug it before bed the night before.
Using Voltage Control to cap the clockspeed is also a great way to save battery. Unless I'm really doing something where I need the juice, when I'm out and about I basically always cap my CPU at 800MHz, or when my battery's starting to get low at 600MHz . You'd be surprised how well the phone will still run and how long the battery can last when capping the CPU.
Yeah my brightness is always down. And I'm normally 800. What undervolt settings are you running? I haven't really played with voltage control.
Sent from my SCH-I500
I got everything running under -50 mV you may be able to push it further I honestly don't know, I haven't played with it much either.
I had a couple of restarts today which I'm assuming is from my UV. If not, I screwed something else up and it's time to play around with a new ROM.
You can look around in the OTB Reloaded thread and see what others have been running successfully, but each phone handles UVs differently.
I'm going to try that Juice defender and capping it even lower to 800.
Is it safe to turn off our data?
Sent from my SCH-I500
Mobile data? Well...yes but you wont be able to do anything that requires data (the internet).
Are you using a task manager? I really would recommend it. Perhaps you've got a bunch of **** running that you don't realize.
Yeah I am using a task manager. And I'm using juice defender so I was just making sure it was safe for it to shut off my data when my screen is off.

It won't hurt anything just keep in mind you won't get Facebook updates, Twitter updates, etc except for when it cycles on. You can set how often it cycles data and checks for updates in the settings.
I've just never heard anyone having such battery issues. Have you let your phone die a bunch of times or something?
Not really.since I've had the phone its only died on me twice. Its been better with this ROM/kernel.

You can always go to us cellular and swap your battery. It may be that. It wouldn't hurt to try.

SetCPU? Juice Defender on infuse?

Does anyone use either of these apps on the infuse? What settings do you use? Do they help with battery life or make it worse.
Sent from my SAMSUNG-SGH-I997 using XDA Premium App
honestly i just think they waste more battery.
set cpu has it lower the cpu speed when its asleep then raises it again when you turn the screen on. seems like it would waste more battery.
and juice defender. same thing stops process that will eventually start agian more battery drain
ive used juice defender before and it works on some stock roms quite well. however custom roms i used on the captivate had zero improvement. it depends on a lot of things, really how much data the phone uses with the screen off. your sync options and apps will have a big effect. i honestly see no reason to improve the infuse. and at some point custom roms will not need any battery saver apps at all.
gingerbread roms tend to be better out of the box, so if there is a gingerbread update then the battery life should be very good for a stock smartphone
Funny you ask about JuiceDefender because I'm testing it as we speak and have been since early yesterday. I can report that it works pretty well actually. I was out and about for over 12 hours yesterday with JuiceDefender on the Agressive setting and I only lost 30% battery and that was with the screen on for about an hour and a half playing WordFeud (that game gets freakin addictive so I kept turning the screen on and off, on and off, on and off). Had I not been playing that game I bet I would only lost ~10-15%.
Setcpu works for me. I have it on 1200 and low 800 and on demand. When watching videos I set it to high n low to 400.

What settings were you on? I used it yesterday for the first time and it completely killed my battery. I was loosing 8-10% an hour. I had the settings set to check once every 2 hrs that's it. Wifi preferred ect

The Aggressive profile is all I conf'd JuiceDefender to.

[Q] Battery draining extremely fast. Any suggestions?

This rom used to be fine, now it is draining extrememly fast and I don't know why.
I am on Gingerbread KF2 and really haven't done anything else yet. I used to be able to make it through an average day of ~15 or so hours using the phone only for some messages, a call or two, and a few minutes of music. After this type of usage, the battery would be around 70-80% at the lowest usually. This is even with the screen at FULL brightness all day.
About a week ago, it started draining super fast. The same usage runs the phone down to about 20-30%, which is ridiculous. In battery stats, Android OS is always FAR above everything else with like 60%. A couple battery calibrations did nothing. I don't use task killers, but I do check my running apps. OS monitor didn't help me at all, and checking my currently running apps just showed mostly system apps that should not be draining hardly any battery at all.
Any suggestions? I think that about covers it all. This just has me stumped...
go through your apps and see how often they check for updates. there were a lot of updates recently and some settings may have changed. If nothing changed, can you do a quick scan with look out? Just to be safe. Also, try juice defender and set it to aggressive

Lookout didn't pick up anything and I set JuiceDefender to aggressive. Will JuiceDefender warn me of an app using excessive battery?
Nope, that battery is still dropping like crazy. (8% in half an hour from almost no use.)
Maybe I just need to reflash and start over fresh...
It will take a day out two to settle in. is your phone sleeping properly when the screen in off? Press the volume keys once it locks and if it makes the sound then it if still on.

Sleeping just fine.
Yea, I guess if you can't figure it out, you can reflash. That is a pain though. I would say to try out jd for a while longer and see if you get results. fb us usually the culprit for my battery drains, but if you checked all of your apps and changed them to manual, then there isn't much more you can do.try putting your screen to auto brightness

So either juice defender is helping or ADW launcher was using excesive battery. It is working better today after I switched back to launcher pro, but still going down pretty fast.
Sent from my SGH-T959V using XDA App
ADW doesn't really drain much battery for me. It actually uses less RAM compared to LauncherPro and Go Launcher (for me).
I think you should just try reflashing your ROM, maybe flashing the new GB ROMs too.
Also, are you sure you're doing the battery calibrations properly? That might also be an issue.
Maybe it's not your phone or ROM...
I've had several ROMs in the last few weeks and have noticed this behavior on many of them....after searching, I found this.
T-Mobile has apparently noticed some abnormal battery issues in areas with their "4G" HSPA+. They're asking people in their support forum for a bit of info to help them find the issue.
support[dot]t-mobile[dot]com /thread/3544
The problem was initially believed to be affecting the G2 only, but is now believed to be affecting all phones in their "4G" footprint that started when they updated their towers in late July. The update provides the government an emergency channel to use, but it appears that it may be causing network issues.
Thanks for bringing it up, this is affecting me too. i lose 20-40% battery PER HOUR of use on the phone at 25% screen brightness playing a card game online (no wifi, just on HSPA+). This is on a BRAND NEW flash of KH2 (GB 2.3.4).
The top half of the phone gets really hot and battery drains like crazy. ceasing data use cools it down and reverts to normal battery use.

"Hypermiler" (Battery Life) Tips

This is a little bit of a boast, I guess you could say... but also educational in a way.
This is my most recent battery life. I found that when I posted my screenshots, people think they are faked in some way. (Posted it here and other GS3 forums) They are not. I am using the stock battery my phone came with. NOT an extended battery. And you can see from the battery graph that the phone was not charged. I guess this is to show that you can use your phone heavily, and still get amazing battery life.
I am using the stock jellybean leak. Not rooted or unlocked.
This is everything I have done to get good battery life.
-I turned the LED touch lights off (I don't like them, they're so bright)
-I have all vibrations off. My phone does not ever vibrate.
-I have power save on.
-I have S-Voice "wake command" off.
-I have motion control disabled.
-I am almost always on wifi (work & home)
-When I am on wifi, I turn mobile data off.
-When I am going to bed, I put my phone in airplane mode.
-I rely heavily on the task manager, I clear my open windows and under the "RAM" tab I clear memory. Probably once an hour.
-I have my sync OFF. I check my email manually.
-Auto brightness.
-I never partially charge. I let my battery go all the way down to 1% then I charge it to 100%. Always.
-Always have a dark background, if possible.
Thats everything. Mind you, I didn't make or receive any phone calls on this cycle. But I did use my phone, as you can see I didn't just let it sit around. Device idle was like 3%?
Anyone else a "hypermiler" like me? I don't get this much screen time every time, it ranges from 5-7. I've gotten more than this and I've gotten less.
Hope this can help even if it's only a little.

-Clearing the ram too much actually drains the battery more because certain apps will have to auto start again every time you clear memory
-Keeping it at around 0-30% all the time should save you more.(I can still see my screen during the day at 30%)
-That doesn't do anything.

-Are there no A/C outlets in your bedroom?
-What the previous guy said, this is a stupid thing to do. Java was designed around efficient use of resources, and restarting running apps (which would happen, unless you have them removed entirely) would use more processing power than you had saved by not having the tasks running in the first place.
-Using Auto is causing the system to periodically poll the light sensor, draining more battery than used otherwise.
-This is how you kill Li-Ion batteries (one way, at least). The whole spiel about discharging fully, THEN charging fully or the battery will have some sort of "memory" of capacity less than actual capacity is how Ni-Cad rechargables work, not Li-Ions. Li-Ion batteries are the opposite. For superior life, keep them topped up as much as possible. FYI
I hope THIS helped, more than a little.
There are plenty of outlets in my room. Lol I just don't need to use them that often as you can see also I hate getting calls and messages in the middle of the night but I use my phone as an alarm sometimes so airplane mode just seems convenient.
This is just what I do. I mean, some of the things I do may not help at all. But this is what I do with Android phones and I've always gotten really good battery life. I've always, always gone down to 1% then charged up to 100% and I've never had a battery go bad on me. Then again I only ever keep a phone for 1 year. I do know that these batteries don't have the memory problem, I just can't bring myself to not fully discharge or charge. I have mild OCD, for real. Little things like that brother me
I'll play with backlighting to see what that does for me.
I've gotta be doing something right. Idk about the task manager, I've just always liked not having programs running if I don't need them to be. I know they arent "running" but it just gives me peace of mind, I guess.
Thanks for the recommendations I will try them.

You getting really good battery life =/= you getting the best battery life possible.
I have pushed ~2 days of battery life without charging many times on my GS3 (with all the bells and whistles running, just mobile data turned off when i'm not commuting), i just don't have a reliable measurement because:
1. I'm flashing mods/roms/kernels/whatever multiple times per week, and
2. I usually charge my phone when it's convenient, which is fairly often.

I stopped flashing because of my OCD. I mean, I'm not crazy but it causes perfection issues and all the ROMs I was flashing had glitches here and there and Idk if you've known anyone with OCD but with the perfection issue, those glitches were all I could think about. So there went flashing. Lol.
Also comes into play with the charging thing. You seem knowledgeable in what you said but even though you said keeping it topped up is best, in my mind, that's destroying my battery. Lol. I really do appreciate your info though.

I read your post and the first thing that came to mind was, "there is medication for that, you know.":laugh:
Here's my .02. My battery never lasts that long. Not even close. I'd feel disappointed if it did. I bought my gsiii with the intent of gobbling up unlimited data and using the oc'd processor to run apps till the phone is so hot I have to set it down. I've burned up almost 6gigs of data since the 7th. I get around 4 hours of screen on time most generally. I also throw it on a charger whenever I have the chance. My battery rarely dips below 50%. Like others have said, full discharge cycles are for ni-cad batteries. Li-ion doesn't benefit. Good battery life for me is the lg flip phone we have on a diff line that lasts a couple weeks.

Okay, okay, as long as you admit it... I'll stop being a snarky jerk. I'm totally the same way though. Perfectionist to the core.
It's a very bad idea to let the battery go down to 1% regularly, lithium batteries should be charged more often for better life and more cycles
Sorry but I still just don't believe 7 hours of screen on time. 4 is above average even amazing screen on time for this phone and stock battery. I suppose there is the possibility of using 0 percent brightness, or even lux brightness or something similar to get the brightness even lower.
You said you use auto brightness, I'm sorry I just don't buy it.
People with the extended batteries are getting 7 hours of screen on time not stock batteries.
7 hours of screen on time is literally double almost every other phone on the market with stock batteries. I really fail to see how having minimum usage and a high performing rom will get you double screen on time.
Edit: with that said, in my current situation I will never have wifi access plus I tether a lot so I really have yet to personally see screen on time since I rooted. Before root and stock I got about 3.5 of screen on time.
Not trying to be a douche or anything just very curious about how 7 hours comes about.

you dont get 7 hours because you are not doing what op did for perfection, and you just like other "4 hour" guys in this thread. I can confirm 7 hours usage is totally possible and what left can support one day idle time when you turn off data etc. Iusually dont do that because I like my phone work at full functionality, but I also like tinkering around to keep maximum use of juice, by eliminating wake locks and autostart.
killing background helps sometimes because some stupid apps keeping using cpu after backgrounded. op go and get a iphone, its perfect for OCD since it can get zero unwanted background activity, amazing idle time and stable usage with relatively easier configuration and tweaking.
1% is NO. 1 battery killer, heat is NO. 2, top up at 100% is NO. 3. Li based battery is at best 40%. but plaese its just a phone, charge and use anytime you want. phone outdated way earlier than battery.

put my phone through the paces with fantasy football.
held up pretty well. stock battery mind you. on pace for nearly 8 hrs of on screen time. This isnt with typical use though... With typical use I can get 20hrs and 5-6 hrs of screen time. I thought anywhere from 4-6 hours of on screen time was what people were suppposed to be getting.
Yeah we all use our phone differently. I rarely actually talk on the phone with my GS3 because I use my iPhone for that. But everything else I do on my GS3, reading news, some browsing, xda.

Then I shouldn't use the word "usage". I meant 7 hours screen on time. Sometimes I got 8 or more, but only use it continuously after charging, no idle time.

Yet that involves turning off data. IMO the smartphone should always stay online. In my experience, iPhone can get constant -4 ~ -5ma juice flow during idle even with data (2G) and all the push notifications on, which are the only things I want for stay online. I feel its hard to get similar result on my GS3 though.

what you did is pointless. If you leave data on, data is not connected when wifi is connected, and it will connect automatically when no wifi connection.

It's not pointless to me. As I said a few posts before... I have OCD, obsessive compulsive disorder. Things like this affect me. I know that being connected to Wi-Fi that data is not connected, but in my brain, it's as if something is telling me that because my data toggle is on, it's running.
I really can't help it.

I humbly seek the counsel of masters. (battery life)

I used to have great battery life. Nothing spectacular, but I could get around 4 hours screen on time on a single charge.
Somewhere along the line, on my journey of ROM hopping, this has changed. Currently, I'm getting about 30 minutes of screen time before my battery drops to 50%.
Using better battery stats, I think I see that my phone is never sleeping. But I really don't know what I'm looking at or where to start to solve my problem.
I'm currently on Carbon running the latest lean kernel. I'm not undervolted or overclocked, or anything.
I've superwiped my phone. I've killled maps location reporting.

Over/underclocking plus undervolting can help with battery life. DS battery saver can help put your phone to sleep by shutting down apps running in the background.

Turn off Location Services and other apps that require location GPS. They really kill your battery a lot faster. Or you can get Wakeclock Detector from the play store to see which specific app is draining your battery and preventing it from deep sleep. Hope this helps.
Turns out I had an otg wakelock.
I wiped cache and davlik, fixed permissions, and it went away.
Thanks all.
