Any suggestions about my battery life

I know that there are lots of these battery life threads and i have read most of them and I've tried closing processes that i don't need and i have tried setcpu to keep the cpu low when the device is off, which seemed to help some but my phone would shutoff randomly. So last night i had a full battery and went to bed when i woke up 8 hrs later i was at 20% so about 10% an hr not even using the device. I have attached some pics for reference does anyone have any thoughts that might help. Thanks

I don't know about galaxy S but on my X10 the problem was wifi.
When I didn't have a data plan I had wifi on all day and the battery was down in 10h max 12h.
To improve it I had to use JuiceDefender to enable wifi every five minutes for updates..
Try to disable wifi overnight, reboot the phone and see what happens.
By the way, what app you used for those stats?

I don't have wifi enabled, I don't use it that often. the name of the prog is system panel

Very weird indeed. I have my Captivate with Wifi on all day, GPS signal and auto sync and when I go to bed and wake up, the battery hasnt gone down at all. I had the phone go on full battery one day and I even sent a few texts and went online for 10 minutes before it lost just a bit of battery.

Do you have that one LED app installed? The one that shows a little red dot on the corner of your screen when you have a notification?

yes i do.. Why? but it was turned off last night, as its turned off every night

Ok so i tested again last night and I did not have my im+ app running and the battery life was soooo much better. I also did not have system panel running which records all the battery and cpu stats but i'm think its the im+ app that was taking up all the juice. Can anyone think of another app that does skype and facebook but that also does not take up sooo much batter life??? Thanks

Possible he has his set to stay on. While yours may turn off when sleeping.

Open up the dialer and type in *#*#4636#*#*
Go to BATTERY HISTORY>PARTIAL WAKE USAGE and maybe that will show you which app is sucking up your battery life while you sleep.
Also try, if you don't absolutely need an internet connection while you sleep, SMODA widget to turn off your mobile internet. It's quick, free, and painless.

yeah the app that took the most juice was im+

I drained mine down to 5% and charged full a few times and still only got 8 - 10 hours on mine until i flashed to jh2 and now have been getting almost 16 hours with same usage and apps installed. I charge mine at night. I use ebuddy with the piwer saver option turbed on abd it does an ok job.

I have the stock ROM and stock launcher and my battery is awsome! 8 hours and I will still be above 80%.
Brightness: Lowest (manually control via stock stock gesture)
GPS: OFF
Wifi: ON all day
BT: OFF
GMail manual
Other emails accounts hourly for the most part.
Widgets: Google/Fancy Weather
BG: Mostly Black
I have never seen such good battery life on a smart phone.
I could easily get 2 days, but i rather charge every night and then not worry about battery usage.
The wifi/gmail/gps made a big difference, its too bad you can't set gmail to hourly or something lik e that. Some of my email accounts i would like to set longer than hourly.

The last few days have been pretty good one my phone. Used to get maybe 16 hours but my last charge lasted me about 50 hours with moderate browsing, gaming, and voice/text. Juiceplotter is telling me I'll be getting about 47 hours

How many hours with the display on?
Sent from my phone so I apologize for any spelling mistakes

My battery icon depletes one notch when I'm using the screen for about an hour. Some people recommend cycling the battery, in which you do a full drain and immediate full charge, 3 or 4 times. I've done it, but it's hard to say if it explains my good battery life.

let the battery drain COMPLETELY until the phone turns off a couple times, then charge it till 100% without unplugging it.

You don't want to drain the battery that much, those kind of batteries can be damaged. The phone turns off for a reason.
I haven't done the cycle thing and its fine. A lot of that comes from older batteries with the memory problem.

irus, software which is based on data connection drains the battery one way or another. Some apps now support push notifications and IM+ does too. Did you try to use push?

These claims of multiple day charges with moderate use is crazy to me. I have the newest ROM, a black screen, display all the way down, gps off, wifi on when in range, make zero voice calls, run juice, and only have 2 widgets that update every 4 hours. I use my phone for a maximum of 3 hours browsing the web, reading XDA and feedR, checking facebook and the occasional text message. My phone lasts a total of 12 to 14 hours. My battery has a manufacture date of late July. Is there some secret I am not aware of?

3g Data our real battery drain culprit?

So i was doing some messing around and i found that on my phone if i leave data enabled i get ridiculous battery drain while using the phone. Just enabling data and downloading an app of the market dropped me 3%. now if i have 3g data off i get maybe 1-3% drain per hour while using the phone. maybe its just me but i think its 3g data thats draining our battery more then it is the super amoled display.

Yes, 3g data drains the battery. Use the power control widget to turn that, and GPS, off while your not using it. Your battery life will be much better at the expense of things like weather widgets not updating and contacts not syncing.
Now, does this really need to be in the development section??? Come on man, post in general or Q/A or somewhere where it would make sense to post!!!

Yes i know it drains battery but this seems to be excessive compared to other phones ive had (palm pre,htc hero,tmobile g1). Also if there was a Q/A section i would of put it there hehe maybe we can get a mod to make one.

where can i turn off 3g?

I noticed the same thing with my phone. It seem when u do anything regarding the 3G your battery gets murdered. Yesterday i was noticing a 10% an hour battery drain with very little use. Over 5 hours i probably sent/received 4 or 5 text and talked for 4 minutes. Today using Juice Defender i noticed much better performance. Maybe only 4% drain with the same amount of usage.
Hopefully this gets addressed by either samsung or the amazing devs around here.

awesome glad im not the only one with excessive drain from 3g

So how do you disable 3g manually?

I recommend Power Control Plus from the Market.
It allows you to make power widgets including 3G data, SD Card Scan, and a working flashlight app!

Those battery life numbers dont look good...

Geez, I just looked at that battery review. The review does look bad. I get pretty good battery life on my phone. 10+ hours yesterday with heavy media streaming, talk time, playing games & browsing the internet.

Power Control doesnt work for our phones(at least for me), failing to control 4G & 3G.. something is amiss.. doesnt even notice that i have 4G hardware

Try juice defender, turns off data whenever u shut the screen

Isnt there a serious delay when restarting 3G on that setting?.. not only that.. but everytime my screen is on, i dont want 3G running, sometimes im gaming, or doing other none internet related things.
Is there a 3G on demand button in juice or ultimate juice? ie.. only waking if prompted by a service needing the net?

Terrible battery life, please help!

Hello I am new to this forum, I just got the Samsung galaxy s 4g this Wednesday and I was wondering if anyone else was having battery issues. Right now I have my phone set to minimum brightness, auto sync off, black bckground and juice defender on. So I don't understand why am I getting only about 3 hours of battery life when all I'm doing most of the time is surfing the web(this forum) and facebook. I even get better battery life from my dads vibrant which is completely stock, has auto sync on, no juice defender, and screen brightness set to 50%. From reading the stats of both phones, the vibrant 4g is supposed to have a slightly better battery. I also don't understand why if the screen is at the minimum it still takes up 94% of the battery whereas on my dads vibrant 50% screen brightness takes up 30%. Is there anything I can do? Will wiping the battery stats help? If so how do I do that from a stock unrooted vibrant?

Check your notifications settings. I know that Samsung's contacts integration with social networks takes a big toll on the battery, hence why I've disabled it. Also, disable T-Mobile's Contact Backup Sync, just use Google's contacts integration.

Thanks for helping, but yeah I have those disabled already.

Does the trick to fully discharge and recharge 3 times work with these batteries? According the the Li-on technology this is not supposed to be necessary but I've heard stories in the forums of folks getting great battery life on other phones after doing this. Many people also say their batteries work a lot better after a week of use (supposedly after "training" them as well.)
I believe the G2 is clocked down for this reason. You could try CPU-set app, clocking down to 500-800mhz when not gaming.
Anyone tried these tricks?

Im having the same issue with battery life.. for me its a deal breaker.. I use my phone pretty heavily for keeping up with email and a little web browsing as well as talking quite a bit.. My iPhone 3Gs lasted me all day of heavy use and with the SGS4G I have to charge the damn thing at least once a day with light usage and if I have to be on the phone a lot then its twice a day.. Not acceptable at all...
Thats with wifi and gps disabled..
On the 3Gs I had wifi, bluetooth and the gps running all the damn time...

Took my phone off charge at 6:30 this morning haven't put it on charge yet at 88% never had this much juice with the nexus one.

I'm not having any issues with battery life or heating. I use wifi teather most of the day and I'm getting to use it all day without issue. I did cycle my battery 4 times already just in case it matters. FYI

The batteries that our phone uses DOES NOT require u to cycle the battery. In fact, doing so will harm your battery. To avoid damage to your battery always charge ur phone when u r at <15% battery level. Trust me I thought the same until I did the research. I will post more info when I get on my PC later.

I just bought a Galaxy S 4G on wednesday. First android device coming from iphone 3G. I'm still trying to figure out the best way to preserve the battery life.
I took it off the charger at 6:30am and the battery was at about 2% at 8:30pm.
I haven't rooted the phone yet to remove some of the bloatware that comes pre-installed.
I've got email accounts synching, brightness set at about 10% w/ a static wallpaper. Played about an hour of angrybirds throughout the day and didn't really do any web browsing with a few phones calls. I mean 14 hours is decent but from what I've read there are plenty of people getting a full day of use and still have 50% battery left.
I guess once the battery fully charges I'll put inception on, turn off syncing and try a few other things.
So I guess I said all that to say this, my battery life isn't great but it's not downright horrible either. Any suggestions would be much appreciated.
And yes I'll continue browsing all the forums to see what else I can find.
Edit:
Played through half of Inception in airplane mode, brightness at minimum. I dropped from 93% to 80% in an hour and a half. Not too shabby.
Also created a shortcut to toggle between 4G modes and Edge. I know 4G is going to be a pretty big drain so I'll see how much that helps.
I'll keep tweaking it.

this is completely true and if you read the manual on page 13- h t t p:// downloadcenter . samsung . com/content/UM/201102/20110224044646930/T959_Galaxy_S_4G_English_User_Manual.pdf it says that
"• Do not wait until your battery is completely depleted before charging
your device. Repeating this process of a complete discharge and
recharge can over time reduce the storage capacity of any battery."
right now my phone is at 23% battery level with up time of 46:46:40 hrs/mins/secs. with skype calling (around 10 minutes), text messaging, browsing the net (for around 5 minutes about 6 times a day), and talking on the phone (around 15 minutes)
the settings i did:
1. took a picture with my finger blocking the camera to get pitch black picture and set that as my background and deleted all the shortcut icons (i short, i only have a blank screen with the only 4 icons down below)
2. changed the brightness settings to 2 clicks to the right from 0% brightness (or you can lower your brightness all the way down during the night, and 2 clicks away during the day, this will save you more)
3. disabled haptic feedbacks and audible touchtones, selections, and screen lock sounds
4. disabled animations
5. disabled background data and syncing when not in use
6. disabled packet data (3g), wifi, and gps when not in use
the last two are the biggest settings that made my battery last longer.
7. i only charge my phone when it gets to 20% and the manual recommends not to use the phone while charging
i hope this helps.
and yes it is recommended to charge your battery to 100% before you turn on your phone for the first time and this is also stated on the manual.
one more thing, don't forget to set your browser's brightness setting as well

Terrible battery life... Suggestions?

Flashed CleanROM V and did a battery calibration running it down to 0% a couple times but getting terrible battery life still. I work in a concrete warehouse all day so the signal is pretty weak. Any suggestions and maximizing my battery?

Perhaps try turning off wifi if you've not got a signal & try kicking the phone back to 3g.

The screen on to awake ratios should roughly be similar but it looks different in this case, install BetterBatteryStats to check out wakelocks.
Also, your mobile signal appears to be very weak and dropping out.
PS. Wiping battery stats does nothing

Wow, you should be getting easily double that if not triple the usage.
First thing, if you are in a area where wifi is available, you can disable mobile data(3g/4g) completely. if not, then leave wifi turned off and use 3g, i dont use 4g lte unless im downloading something BIG.
Secondly, if you want to, you can close the apps via task switcher every few hrs, but not mandoatory.
Lastly, update your device to the latest version 2.20 or 2.40. I got easily 15-20% increase when i updated from 1.85 to 2.20.
Also you can leave your screen to auto brightness, which helps by itself, i used to change it myself but i realized auto is better since it changes it instantly depending on the situation.
Doing this gets my phone to average 30hrs standby with about 3hrs screen on time. Heck, few times when i used wifi mostly and data turned off majority of the time, i got 5+ hrs screen on time within about 24hrs usage.

That's what I'm saying! For such a great phone I should be able to use it more at least I'll look into disabling 4g. LTE just got turned on in my area and i'm soaking in the super fast speeds Probably not worth the sacrifice in battery if that's the case though.

"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.

-I rely heavily on the task manager, I clear my open windows and under the "RAM" tab I clear memory. Probably once an hour.
-Auto brightness.
-I never partially charge. I let my battery go all the way down to 1% then I charge it to 100%. Always.

-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'm glad you said it, so that I didn't have to. :silly:
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.

While I understand what you're saying I think you misread my post. I was strickly referring to the screen on time which 7 hours of screen on time with stock battery is inconceivable. 4 is about the most you would normally see.
7 hours of USAGE is common.

Well I mean. You don't have to believe me. I mean I have nothing to offer but my word. I do use auto brightness. But because of the suggestion I'll probably set it to manual and see what that does.
I got 7 hours screen on time with the stock battery. The battery says "3.8 v li-ion battery"
I've gotten more than this is the past but I've also gotten less.
Like I said you don't have to believe me but... I'm using the stock battery.
And to the poster who mentioned to get an iPhone - I have one for my business line

battery statistics are poor statistics in general. there are too many variables. luckily we have removeable batteries if we need mroe juice.
heres some postings to add to the mix
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.
I just thought I'd share what I do for people that may want to get better battery life.

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.

I'm always online, whether it's wi-fi or 4G. Luckily I have wi-fi at home and at work.
Like, literally as I'm walking out the door of my house, I turn on my mobile data, and when I get to work I turn it off. When I'm leaving work I turn mobile data back on and when I get home I turn it off.

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.
