hello, before all, i know there are too many posts about improving battery life and other, but i wanted to ask my personal case. i have SGSII 2.3.6 v6, based on stock DDKQ8 2.3.6.
The thing is that having wifi, the battery life is almost normal, for a 1360 mAh battery, but with 2G or 3G the battery draining is too big, for example using only whatsapp with 2G, the battery drops so quickly, i have tried all, underclocking the phone, clearing battery stats and all kind of tricks, thank you.
The radio hardware on the phone besides the visor ilumination in one of the thing that most battery consumes!
Even if you have no mobile data on, its always consuming! when you turn that on! the usage of the radio hardware on the phone gets 5X active and thats why the battery drains so fast! if you are on a area that has poor service ... add 1 more to those 5 times!
This phone was not made to endure that "pain"
my phone can last up to 3 days on DDQ8 stocklite v6 ... and i still use it in a normal way! use mobile data! Use wi-fi! etc ...
but ... i always turn both off when not using (3G and Wi-Fi) my visor ilumination is almost at the minimum! have no animation! have no sync on ... its bad? yeeessss
Ace battery SUCK's in wathever ROM you install it ... accept it ... all we can do is minimize the "damage"
You have to choose performance or battery! Both? Nearly impossible
Enjoy your ace!
thank you very much for you advice! i will try to follow it, and then i tell you, but apart from that, i want to see more advice or something, but whatever, thank you

Try the GreenPower app. It can save a lot of juice.
SnowPluralism is right. Check your batt stats and it should say cell radio has a high percentage of your batt drain. Juicedefender (& Greenpower suggested above) is an app that regulates your data, turning it off whenever your screen is off (and turning on for when your phone requests data sync). Not much more can be done.
yeah.. all battery power saver application will only regulate the data communication, gps, screen brightness.
the most energy consume is data communication. as we all know, android also have the background data communication. so eventhough the sync off, it still consume a lot of batery.
turning off the data communication will save a lot of batery.
but, android without data communication? same as blackberry without BIS (blackberry internet service). just a dumb phone
okay guys, as you are saying, im going to focus in regulate data connection, im going to try GreenPower and juicedefender, then i will come back and tell you!

Hi Everyone,
I am disappointed with the battery of Optimus One.
My Battery in Standby (GPS/Wi-fi/3g/Sync/Screen, ALL OFF and without USE ), does not last even 20 hours.
I have an application that shows what application is consuming more battery power and the "phone in standby mode" takes up 95%!
What are your experiences with this battery?
Mine has problems?
Thx
I bought it one week ago and the battery last one day with no problem (and it's not at its full "potential" since is new). When did you buy the phone?
I bought it 2 weeks ago
Using a custom rom you won't be disappointed with your battery no more...
I have openOptimus Rom with Franco kernel 15. I am at 85% battery after 14 hours. The phone has been pretty much idle.
Only 2G networks
Data disabled
Wi-fi on
Auto-sync on
Overclocked 480/729 interactive (interactive may not be optimal)
I'm using franco kernel v15.1 with devoid.franco, i'll try do update do devoid.froyo.final today.

Hi, what is data disabled? and how to put only 2g networks?
20 hours on idling? Send it back for repair/replace. Mine will last days if left idling (about 1% every two hours)
When I travel I turn all data connections off (Bluetooth, wifi, gps, data) and it lasts about 3days

Here are some potential things to turn off that might make the battery last longer. They are all in the settings app. I do not do all these since I find that some things might make the battery last longer but reduce the usefulness of the phone.
Setting/Display/Brightness
Setting/wireless & networks/wi-fi off
Setting/wireless & networks/bluetooth off*
Setting/wireless & networks/mobile networks/use only 2G networks*
Setting/wireless & networks/mobile networks/data enabled off* (I have this turned off all the time as I do not have a data plan.)
The items * I have off unless I am actively using them. I also overclock my Optimus. I think that this probably gives me a longer battery life, since it is running at 480 when I am not using it. I suppose if I was desperate, I would undercloack the phone (min 480 and max 480).
What version of Android are you running? 2.2 or 2.2.1/2.2.2?
When you click on Cell Standby, how much Time Without Signal does it show?
follow these steps and i think ull have what you want..
go to battery use and click on cell standby : then see time without signal. how much does it show ? if its above even one percent (unless uve mannually put ur device in airplane mode) i know the problem.
go to settings >wireless & network settings > mobile network > mark 2G only (if u are not using 3G) cause the cell might spen loads of battery searching for 3G.. then go to network operators and search for (mannually) and select ur own network provider.. like mine is airtel.. then let your battery run down totally.. completly to zero. then recharge your phone to full without any break.. this is called recaliberation. then see how much your battery lasts..
remember to turn off bletooth, wifi, internet, all ! while the phone is idle and you wont be using it for sometime. or, if you wont be doing or getting any calls or sms, consider switching to airplane mode..
you might be getting less battery if ur in a area with weak signal strength.. this makes the phone go wilder to search for signal. in these conditions, switch to airplane mode if you can . thatll save a lot of battery. and also during night if you want to.
dont hesitate to click the thanx if i helped !
EDIT: and ya every thing that the person after me 'Y.u.v.i' said.. though those are normal things and brightness level is most important..
and about francos kernel, ive had many f/c s with mik's cm7 beta 6.2.5 ..i prefer its own kernel , though dunno for other roms.. u might wanna try it.. ill try myself too..
yes ..few step here u can try
1.reduce ur brightness level to minimum ...
2. use 2g signal only.
3. turn off all extra connection like wi-fi , Bluetooth, auto sync , data.
4. use advance task killer and set it to auto kill app aftr every 30 mints.
5.automatic screen time to 30 sec.
6.if u r using custom ROM use Franco 15.1 kernal . and wipe battery after charging it up-to 100%
use thanks if u like my post ...
I did all the tips posted here. Let us now see what happens

I'm using 2.2
7% without signal.
Sorry for the dumb question (about 2.2 or 2.2.x) - I didn't read the first page carefully enough.
Try this: reboot, then enable airplane mode, lock your screen and leave it like that for about a minute, unlock screen, disable airplane mode.
Are you still seeing Time Without Signal? (of course, after a few hours, not straight away)
EDIT:
DON'T do any of the following:
- reduce brightness to 1%... come on, be serious! you really like squinting at the screen? screen brightness doesn't affect battery life that much anyway...
- don't use task killers! it doesn't matter if you have little RAM - it's there to be used. I will not go into details about this (there's whole threads about it), but trust me!
You could also try monitoring your apps with https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result and see if any of them start behaving wildly and keep your CPU awake.
Another thing would be to try Nessy Hypnos2... I had great battery life when using that ROM! If you're still experiencing the same battery drain with a fresh install of Hypnos, then I'm sorry to tell you but you'll probably have to send your phone for repairs.
I ended up recharging the phone two hours ago and it is at 91%.
Was 9% in 2 Hours - 4,5% per Hour. Very Bad...
...with nothing in use.
Only 2g networks
wi-fi/dates/sync/bluetooth ( ALL OFF )
Screen OFF (black, with -0% of brigth, because he is OFF)
I install Battery Monitor Widget that estimates my uses of battery in:
18h52m of Discharge (100->0%)
and 5h of charg in USB and 3h of charge inc AC.
I'm installing watchdog now, to see if have an App draining battery.
EDIT:
But I do not think that's because I have an application that shows the the CPU clock in%.
480MHz = 80%
729Mh = 20% or less
and another that shows the applications that consume battery
and Cell Standby = 90%

I got the same. My phone is also on the same settings, same rom, same kernel. Battery life was awesome some days ago, but now I experience average battery drain, I think I need to callibrate my phone as well. :/ I will do it probably after flashing void.final.
Are there any good ways to extend battery life besides the obvious stuff (no WiFi, GPS, screen brightness, etc.)? I just converted from my iPhone 4 to a Nexus S and battery life is pretty miserable - I can make it through a day but I have to plug in as soon as I get home. If I could stretch that 12 hours to 18 or so it'd be perfect. My iPhone could do 24-36 no problem, so I feel like 18 should be reasonable.
You can try different kernels for your firmware. The custom ones (good ones) normally consume less battery.
You can try to calibrate your battery, as well.
That is if you're rooted. If you're not there's not that much you can do. Install Current Widget from the market and let it be in standby for around 1 hour with WiFi and that stuff off, and check how many mA it's draining.
Other than that, turn auto sync off, and don't let everything send out push notifications (news readers, Facebook etc.) and if you're using a weather widget check that it's not updating every 30 mins or something.
BazookaAce, but having a smatphone like this without being rooted it's a waste of gadget...IMO.
Yeah, I'm rooted and running brainmaster's MIUI ROM. I do have syncing turned on for everything, I'll try messing with that since I certainly don't need FB or Twitter updates every 30 seconds.
just dont use any of battery saver tools. it doesnt work. wipe battery stat if ur phone rooted.
I have a similar problem. I am running an XT860 and am barely getting 12 hours and that's with an extended battery! I have read that keeping the software on your phone up to date usually improves the battery life.
What kind of droid do you have?
Root your phone, install cyanogen or miui.
Download setcpu app.
In setcpu, set it so your phone uses 500-600 mhz of processor speed when the screen is off.
That alone should help your battery life by at least 25%.
Not so sure setCPU is the end all solution here. I have this as well and I have mine actually down to 245mhz when in screen off mode, yet my battery life still is horrible. I have screen brightness pretty low and only gmail is setup to autosync, and checking the stats gmail does not use much of the battery.
I think it also has a lot to do with how good of a signal you get in your area. If your phone is constantly cycling through to get a signal that will eat up your battery as well and is pretty much out of your control.
Dropping the speed with the battery life sucks hd2 setcpu that does not taste at all
I know this question has been asked really lots of times, but I didn't seem to find cases similar to mine.
there doesn't seem to be any wakelock (except 2 which is incredibly short) and it was in deep sleep mode all the time. but yet, it drains almost 5% per hour which i find is really too much...
I've tried lots of firmware (litening, wamanlite, turkbey, stock, ICS) and removed all the unnecessary bloatware to reduce wakelocks to a state as shown in attachment. but still, they do not have any results, still get less than 1 day life without any usage at all...
Could this be hardware problem? I find it gets hot really fast even when i'm just facebooking.
Or is there anything else can i try to do? this device really started to disappoint me ever since the battery life looks like this.
any help will be greatly appreciated.

maybe try out BetterBatteryStats, duuno but maybe this could help?!
cheers and good luck!
Try Hydrogen-ICS latest version, it seems to be "the rom" today
Battery life is very good and its overall a stable system.
Make sure to "Fix Permission" after first start, reboot recovery and do it.
Also sometimes "to much junk" in your SD card can cause battery drain, copy your files and format the SD card, you might see some diffrence. (i did)

you got 20Hrs out of your phone? grats! as of lately i've been trying alot of different roms and different customization settings from kernel tweeks to CPU tweeks (undervolting/underclocking) and im even turning off every extra setting that consumes battery power apart from wifi
on best with a 2000Mah battery i get 13 hrs on standby and 4 hrs if im playing a game - these days my phone doesnt charge anymore - it discharges even when plugged in
I recommend downloading HydrogenICS, it's good! Download Battery drain, so you can see how fast your battery is being drained.. Also, let your battery go down to 5% then charge your phone
Something is seriously wrong - you've hardly used it, looking at those graphs.
I'd try a stock anything, and if you get similar drainage send it in for repair/buy a new battery.
this is'nt normal , in sleep mode i can get 20 hours and only lose 9%
use hydrogen and neak , and try , if you get the same result so it will be hardware fault
the 3g data it kills the batt very fast,i don think u got a hardware prblm,cause 20hrs an still to go is good ive seen ppl reporting worse...dude instal better batt stat,3g watch dog but remember batt saver apps too run in bckgrnd so i suggest u stay on a stable rom wiv a custum kernel like siyah or neak an watch the batt in better batt stat.....wen i need more juice i switch to airplane mode in nite then rebot in the morning....i don hav any tweaks or uv,oc but ive seen the batt is very good wen i don use the data or wifi or download or update,pm me if any doubt......cheeeerz
You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.
I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

bro, 20 hours is with 99% deep sleep is seriously wrong. better battery stats cant tell me nothing, since i have no wakelocks or whatever, and all those battery savers apps, they spent more battery than they can save. when those screenshot is taken, i can tell you for sure, bluetooth, gps, 3g, wifi, auto sync etc everything was turned off. even brightness is 10% (which is even lower than auto brightness settings). anyway thanks for the reply

nope, i always try at least 5-6 battery cycles after flashing to see the real graph. and i've read in this forum somewhere, calibrating battery by deleting batterystats is useless for this phone.

speedmod is a kernel like siyah rite? i've use siyah before, but it doesn't seem like much help. nonetheless, will try them ^^
thanks for all the replies and recommendation, will try different rom & update again (probably in 4-5 days for trying 2 roms
I have exactly same problem. On GB over night(7 hours), battery consumption was around 9%. On ICS more than 20%, but nobody touch phone. I try few roms: wanamlite, omega, bezke, pure. Now i have hydrogen. Better battery stats shows nothing special. Only thing what i can think is wi-fi. if i turn off seams to be better, not that dramatic, but anyway not that good like on GB.
strange...
let me ask this... what does the yellow color in the phone signal mean? anybody got any clue?
shouldn't it be green/gray ?
in my phone whenever i have green/gray in the battery view the bar hardly goes down on idle but i see a big drain compared to green/gray when it becomes yellow even in idle
let me post a pic to clarify...
i was complaining about sudden batt drop on cm9 ics, i know its 2 diff roms but still the yellow bar got my attention in both pics...
just searched google and came up with red= no signal, yellow=very bad signal to no signal, green = good signal/full
bad signal makes the phone look for the signal in a bad way using a lot of the battery...
guess i found out why my batt suddenly dropped so bad compared to the rest of the bar...
id suggest flashing a couple of modems and testing how good of a signal u get with each and sticking with the one that works for u, if its a weak signal from the provider then find a better provider that covers ur place with better reception...
start from there and then if batt life is still bad search search and search... best of luck with ur phone...
@mazroui
in those 7 hours your phone should lost 9 - 10% of battery, but not more than 20 unused, what is process causing that usage?
for me: i charged phone before sleep, when wake up after 7h i had 20% left.
Android OS - 92% , rest for cell standby, phone idle and screen. Wi-fi was setup to sleep when screen is off. Better batery stats show that wi-fi was on for almost whole time
Cell Standby and Phone Idle using that much of your power means that the signal in your area is horrible and the phone is struggling to maintain a decent connection with the towers, this can drain a tremendous amount of battery depending on how bad the signal really is, the yellow bar means it's not optimal but there is a large degree of variation between the top end and bottom end of the yellow bar spectrum. Try a different modem or move your phone to an area with better reception and see if you still get this sort of drain.
Android OS is misreported by practically every Kernel because for some reason Samsung accidentally made Screen On add to the Android OS bar, so your Android OS usage is actually AOS + Screen On, for the most part high AOS usage can be ignored as a source of drain using the phone info battery screen, I would look elsewhere for the problem. Sometimes rogue apps hide their wake locks in another wake lock, for instance if you have facebook or many of the IM programs on your system, they poll their servers a lot causing a kernel wake lock called 'svnet dormancy' (in gb) or 'multipdp' (in ics) this causes a lock of 5s to ensure proper packet transfer, if your app is requesting packets every 4 seconds, then its essentially a permanent wake lock but may not be reported as the app being the source.

There is a defect with Android where good signal strength is mis-reported on this screen as yellow, even if you have 100% signal.
Until you go to About Phone > Status, just once. Then when you go back to this screen, it will start reporting as green if you have good signal.
I've tested this out on my phone, and confirmed it... try it out yourself.
I stopped caring about it, so I just ignore it unless it gets reported as red.

Signal in my area is far from perfection, but in same location, on GB i had 9% consumed over night, but not 70 %. I turn off GPS, BT, leave only wi-fi and data. And over night when nobody touch phone, screen is off.

If you look at the graph in the right pic you can see that the curve is less severe when WiFi is active, while this doesn't prove my point that its a network issue it does increase my suspicion that the issue is mobile data related.

Something is horribly wrong with that. Do a full wipe. If it still does that, reflash your firmware. If it STILL does that, maybe flash to a newer stock ICS firmware? Then as a last resort, you may want to go back to GB.

This guy may be onto something, actually. First thing you should try is flashing a different modem. THEN do all the stuff I said above.
EDIT: just noticed you're in Oz. Try flashing a T modem. Most Australian users report much better results with both battery and signal after doing this.
Hi all,
I'm new in this forum so I hope to break no rules in my first post. So first of all: I'm fighting this problem for nearly a year right now, I tried so many things I can't even remember and I really never found a answer in any forum.
I had a Samsung Nexus S which started to have this strange Android OS battery drain some weeks before the OTA ICS came in. I read thousands of forum posts to try tons of stuff to solve the problem without any success.
I then decided three weeks ago that it's obviously time to get a new phone so that I bought the Galaxy SIII (int). Strangely I still have great problems with my battery life which brought me here to ask some pros now.
Phone: Samsung Galaxy SIII (int)
ROM: StockROM (4.1.1) and CM10 Nightly
Carrier: German E-Plus
What is the most noticeable about the battery drain is, that it appears in standby (over night) in both ROMs, Stock and CM10 likewise with some minor differences.
In 10h standby (Wifi on, Bluetooth, GPS, NFC all off, only few widgets, AquaMail on push) battery goes down from 100% to 70%.
After all, I tested both ROMs in the same situation over night and the bettery drain is pretty comparable (see the screenshots).
What I already tried (in both ROMs):
- disable all Google Maps autostarts and disable all location services
- disable apps like Gtalk, G+ etc.
- uninstall AquaMail
without any effect on the standby battery drain...
Any idea about this?
Thank you,
Mika

What is the most noticeable about the battery drain is, that it appears in standby (over night) in both ROMs, Stock and CM10 likewise with some minor differences.
In 10h standby (Wifi on, Bluetooth, GPS, NFC all off, only few widgets, AquaMail on push) battery goes down from 100% to 70%.

It can happen if u have a weak network signal. It takes out a whole lot of battery. And with wifi on, I believe that's a decent battery life. And try putting the phone on flight mode during night. Saves a real bunch of juice. And do a cache clean and reboot.

Thanks for the quick reply! About the network signal: in both cases the signal was pretty good. Did you check the screenshots? In both ROMs the NetworkLocationLocator seems to use much battery during night. Is that normal in standby?
What is strange as well is, that after I changed the SIM card into my new phone, did a factory reset on the old one (which I did several times before) and installed some basic stuff with a different google account, it looses some 10% in 24h in standby with Wifi on.
Is there any possibility, the battery life changes significantly with changing the google account because of differences in the contact or calendar app or whatever? Or could be the missing SIM be the huge difference in battery life?
Thanks again

Disable all sensors gs 3 has loads of them for smart stay front cam needs to be on always which drains battery.. So that should help the case

With wifi on, that's a real good battery life.! A whole day and just 10%. And I don't think battery life has anything to do with the Google account. If u have turned on auto sync, that's gonna consume some battery too as the apps like fb keep running in background.

Hi Lifehacker7,
like I wrote, the 24h and 10% do not concern the Galaxy SIII but my old phone.
Maybe I have to clarify that again: it's not about a general battery life but about the standby power consumption. Maybe someone could have a look at the screenshots. I guess they might be very helpfull!
And again: there are two different ROMs I tried. So it could have nothing to do with the sensors and stuff since the CM10 does not use them at all...
Cheers,
Mika
nice ideas
Anybody who could maybe have a look at the BetterBatteryStats screenshots and say whether there's something conspicuous?
Is for example the deep sleep mode with its 75% in standby normal or should that be less?
Should be the Android OS (in CM10 ROM) or Android System (in StockROM) be the most power consuming process? With my old phone its always the Wifi which is first in list.
Should Google Maps with its three processes, especially the NetworkLocationLocator (see the screenshot of the StockROM) wake up the system so often in the night?
Any ideas?

No, I even turned off the location services completely, without any effect!
I tested both phones, my old and my new one again this night with the same turned on/off (Wifi on, GPS off, auto sync on, ...) both with a SIM card with the same carrier and both with some apps like fb, whatsapp, weather widget. Old one lost 3% in 8h, new one lost 21% in the same time.
No ideas?
You can see a bunch of threads on the google forums already regarding miserable battery life on Android 4.2.x because of LocationServices
Anyways, try this on CM10.x ...disable Location services (GPS + Wireless) ..reboot ... now enable the GPS only ... if it asks that Google will collect data in background, blah blah select Disagree ... reboot
Using Developer Option menu enable onscreen CPU Usage and leave phone on standby ... you will see that Android OS usage will come down drastically (almost stop!)

Thanks for your idea!
I tried that in StockROM, and it did not change anything, same battery drain in standby. The NetworkLocationLocator in BetterBatteryStats is not listed under partial Wakelocks anymore. So I think, that's not the problem.
Any idea?

This is the 8 hours after I turned off location services on StockROM. I barely used the phone this 8 hours.
Hi everyone,
I have an lg optimus l9 p765, i mainly bought it for the battery thought it might b having a good battery life, but instead my device lasts for hardly a day with moderate - low usage. i just use whatsapp not even games, even i use it for calling (only 2g network not even 3g), is the battery life that bad? any solution for this? i'm on stock ics 4.0.4

Check your battery usage. What is using most of your battery?
Turning screen brightness to 50% will obviously help more than just about anything else. Also make sure there aren't any issues with Media Scanner eating battery (sometimes it hangs in the background and does not let the device go to sleep--this made my battery behave very similar to yours).
Is your phone overclocked? Are processes running in the background? Once I solved my media scanner solution, my phone lasts for a couple days with moderate usage (games, wifi web).
Let us know what things are using the most of your battery (settings>power saver>battery use) and maybe we can go from there.
