Use Advanced Task Killer to try and help and my screen is not set to bright...any suggestions would be great however, I had good battery life until the first update to 4.1, then its gone downhill from there and I haven't changed my settings nor habbits. Thanks in advance for everyones input...if you'd like additional info for your records just let me know how I can help. Thanks.

Advance Task Killer isn't doing you any good. It was determined a long time ago those things did more harm then good. Android has its own memory tasker.
[Nexus S General] rcrd-pt:
stock 4.1.2. the only apps i use to increase battery life are timed tasks free (to turn airplane mode on between 2 and 7 am) and screen filter at night. normal use, data off, and a little wifi at night to check email and fb. 4 days long. but i could do 5 :)
[Nexus S General] the_real_nwags:
Great 4.1.2 Battery Life

I was getting some mega drain on the stock 4.1.1 recently and I thought my battery may be going.

I then saw the 4.2.2 update was out so I wiped everything and restarted on stock 4.1.2 rooted. Battery life has by far been the best of any ROM I have used.

The drain on 4.1.1 seemed to be coming from the Exchange services, but is no more since the reset & upgrade. Could have been the reset too though.

You have amazing cell reception which is greatly contributing to you being able to fully utilize your phone.
[Nexus S General] ScOULaris:
Yup. People really underestimate this. The difference in battery life between when I'm at work all day with terrible reception and when I'm out and about on the weekends with full bars is ENORMOUS. I'm talking 1.5 times the battery life on weekend days.
[Nexus S General] Babyrasta:
Hi!!

Here are my stats!

Mobile data enabled all the Day, just switching on 2g when idle!

Also, about 1 hour of music playing with Audiogalaxy which explain the multimedia server drain ((screen off but 3g enabled for better streaming)

I'm just about to go back to ICS after weeks of battling with battery life on JB ROMs. I used to have 90% battery left after a day in the office on CheckROM v3.5. Now I'm lucky if I have 70% (with the same apps restored using TB, the same sync/location settings and Google Now disabled). I usually syn Google mail, contacts and calendar but nothing else.

I've tried CheckROM v6, various Wanam Lite releases, AnonoROM, Omega and none can come close to matching the battery life I had with ICS.

Back to CheckROM v3.5 I think....

[Nexus S General] Mr.KaiDi:
after trying lots of jb roms, i can conclude that none of them can compare with the long battery life in ics. usually ics can stand for almost a day with normal usage, but jb can only stand for half a day.
[Nexus S General] lurtis:
Went back to cm9.1 stable and I must say...not really missing jb at all. I think the initial omg its project butter has worn off for me. Apps seem to open just as fast on cm9 IMO. And the better battery is definitely welcome. Its great we get updates for our old phone its hardware just wasn't built for it no matter how you look at it.
[Nexus S General] gfinockio:
Here's my first full real test of usage under a new kernel - I ended up going to about 20% with 3+ hours of screen time, some music streaming (maybe an hour or so), some Youtube videos and emails/texts. A 5 minute phone call in the middle there somewhere too.

It's certainly the 3G data that sucks the battery - if I can find WiFi, I'll use WiFi.
[Nexus S General] itm:
3 days back on ICS now (CheckROM v3.5) and it's great to have the old battery life back. I'm now consuming about 1% battery per hour, compared with 2+% with all of the JB ROMs that I tried (with exactly the same apps, sync settings, wifi environment and general usage). I'd be really curious to know why JB consumes so much more battery performing the same workload.
[Nexus S General] Ted Mosby:
Is there any particular reason why I shouldn't rollback to ICS from JB?

I bought my NS with JellyBean already installed so I don't have any experience with ICS. I could use some extra battery time but I am afraid that the performance isn't same.

Thanks
[Nexus S General] itm:
I haven't noticed any difference in general performance since switching back from JB to ICS. I haven't missed any of the JB features either.
[Nexus S General] unlinker:
Mee too. I'm back to ICS because I'm bored with poor battery life of all JB roms (or stock). Pick a good ROM and you won't see any big difference.
[Nexus S General] nakTT:
I my case the "mediaserver" is the culprit when it comes to battery drain.
[Nexus S General] ykphuah:
This comes up once in a while also, I found rebooting helps.

Yes, most of the time rebooting helps but still, android shouldn't have this issue in the first place, right?

[Nexus S General] madd0g:
The sgs toolbox app finds corrupted files and removes them, which fixes the mediaserver lock. Otherwise the mediaserver is listed also while listening to media.

I don't have the problem with the mediaserver but with cell standby any fix ?

i have no problems in jellybean

i haven;t seen any problems on heavy use it lasts about 6 hours but on normal use calls , wifi and a few hours of music it last's a lot

for example yesterday was used at max 3 hours calls 2 hours wifi, and 2 hours of music and it took 12 hours to drain the battery.

i'm using stock Android 4.1.2 jellybean
[Nexus S General] ross231:
I'm on stock, rooted, and i get 6-8 hours light usage. (no gaming, just reddit, music, ect) how can i make my battery last longer?
[Nexus S General] Killasmoke:
Turn off data when not using the phone you can still get calls &text turn off location in settings also use WiFi if you can instead of data.
[Nexus S General] sidnoit22:
Use greenify app it saves RAM and Battery, :)
[Nexus S General] 4I-I:
also maybe try a custom kernel if youre able to flash stuff! It helped my battery life enormeously! ;)

For me, the battery life for ICS and JB almost the same:D
[Nexus S General] fenrry:
...for some reason I can't check my battery stats, I go System settings > About Phone > Status > Battery level....nothing, if I select Battery Status I have the same issue, there is no info or screens...does anybody know if this is a bug?

Lol..settings>battery......

[Nexus S General] anshumandash:
My Nexus S battery life is really bad since the upgrade. I am able to get about 14 hours with min usage like 1.5 hours screen time, 20 mins of call and 3g on. I am not sure what started this. I used to get good battery with ICS. Then to get OTA I did the Google Service Framework trick. I did not get OTA, but I think that is the time the battery issue started. Next 1-2 days I was so busy trying to get any source for the OTA that I did not count anything, but I remember charging the phone multiple times.

On 20th I got the OTA and then I observed that battery life was bad. I have tried deleting all google accounts and re-configuring again.

Better Battery Stats shows like this. I have only put the top most stats that I see and not everything.

Kernel Wakelocks: Power Management Service - 39 mins, modem_ip_rx - 23 mins, radio interface - 10 mins

Partial wakelocks: GTALK_sync_Conn_com.google.. - 13 mins, Touchdown *overflow* - 12 mins, Alarm Manager - 5 mins, Activity Manager - 4 mins, RILJ - 4 mins

Gtalk is never logged in, but not sure if this is just google sync. I have gmail & contacts sync on. I use Touchdown for my exchange email.

Does it show anything really wrong?
[Nexus S General] MichelN:
Disable 3G and your battery life will double if not tripple the life.
[Nexus S General] insane youth:
after just over a days use on jb i would say the battery drain is very similar to what it was on ics, and i had pretty good battery life on that
[Nexus S General] alexcinci:
I have the overall impression that is almost the same. But I notice that on hard use, the battery goes away faster.

For a finally impression, for me, Ineed about 2 weeks or more....

JB stock non rooted

im getting massive battery drain from media server too...does anyone know how to fix this?

im on stock jelly bean btw
[Nexus S General] sacosta115:
A New Battery?

Would A higher mhA battery work with the better than the original 1400 mhA battery as far as battery life goes?
[Nexus S General] chronophase1:
If you get a reputable battery with a higher mAh rating, it will last longer. If it's just a few mAh, like 1600 compared to either the 1440 or 1500, it'll be a minor, if any noticeable improvement.
[Nexus S General] wchrisyu:
I swear just sitting idle on my desk for most of a day it loses a little to ICS.

My habits and use haven't made me notice any real change.

I don't feel like if I don't charge it constantly I'm going to miss out on something (like a chick with an Evo).

[Nexus S General] MichelN:
I can safely say that my batterylife got doubled with 3G on. In ICS i needed to charge everyday but now i have 67% battery life and the phone is off the charge for over 16 hours. :cool:
[Nexus S General] Brewbud:
Installed the OTA update today. Battery usage looked good. Had a lot of batt life left. Opened up an app to check in and it hung up for a bit.... then dead..completely utterly dead with no warning.

[Nexus S General] chronophase1:
Weird awake time from Phone. Any ideas on what would cause this? It doesn't seem to affect my battery though, strangely enough.
[Nexus S General] Brewbud:
That is what the screen looks like when you pull up the larger view of the batt curve. Agree doesn't make much sense. But it actually shows the oddity that happened pretty well. Hard to explain why the battery just dropped off like that. I work with Lithium batteries and have not seen a discharge like that - at least not one where the the battery came back. Not sure the method or algorithm they are using but I expect it shut down because the battery got hot. The rise time after the dip is the phone back on the charger.
[Nexus S General] wheeqo:
Less than 24h usage (after all sync is done then reboot), I think the battery on jb is better than ics. But in my pessimistic view it's insignificant different between jb n ics in terms of battery life.

- stock kernel, sync only Gmail, juice defender (the same configuration when using ics) -
[Nexus S General] chronophase1:
That's what it pretty much is for me. My battery lasts exactly the same amount as it did before the update. I charge twice a day since I stream music during my lunch break. The phone is usually at 60% give or take 5% by lunch time. I don't see how people are having such huge discrepancies with life. Might be app issues, or they have some of the newer services running constantly.
[Nexus S General] labratqld:
I've had an odd(?) issue. I charged my phone up before bed and let it run overnight to see how it'd go.

I've attached the screenshots of my battery in the morning. About 8 hours of no use, and it went down about 40%.

The issue I've noted is that the first hour or two it's doing what it should, a check every 30 minutes, but then it suddenly is almost constantly checking all night after that. I notice when I wake up that the signal bars are grey.

I'm wondering if overnight, it loses connection to the Google server, and then my phone is spending all night trying to reconnect.

Does that sound likely?

I don't know why my phone loses the Google connection, but I have to turn the data connection off and on again for it to reconnect to Google.

It's rather annoying, because it seems pretty good on the battery otherwise (ie, during the day).

I'm on stock rooted 4.1.1 from this thread "http://xdaforums.com/showthread.php?t=1784497" (sorry, can't post link yet)
[Nexus S General] C4SCA:
i have the same problem with the google services!
[Nexus S General] chronophase1:
Do either one of you guys have Google Now enabled? You two aren't the only ones who are having this issue with Google Services. Google+ seems to be on your list as well. You're one 3g I see. How good is the connection? That may be part of the problem.
[Nexus S General] C4SCA:
google+ sync is turned off for me. and im not on 3g. but every where i go, i have wifi connection bcz my carrier offers me free wifi and they have wifi antenas almost every where in the city
[Nexus S General] ubnub82:
I'm using the CM10 ROM we just got but I seem to have about the same battery I had on ICS.
[Nexus S General] labratqld:
I do have Google Now enabled. The 3G is very good at home. 3-4 bars of service always.

Looking at BetterBatteryStats, the biggest user overnight was "GTALK_ASYNC_CONN_.com.google.android.gsf.gtalkservice.AndroidEndpoint", but I had Google Talk disabled, but I'm thinking that's a generic service name and it's related to Google+ somehow. :confused:

I'll turn G+ sync off and see what difference that makes tonight.

I do find it odd though that the blue bars are there when I go to sleep, but they are grey in the morning.
[Nexus S General] anshumandash:
I have similar issues. GTalk taking up max battery according to better battery stats. I have gtalk & g+ both disabled in app list. I don't think it is generic as gmail & google contacts are appearing separately. I find lot of google services running and draining the battery. Phone. Google Service etc keep the phone awake for long duration. As per a previous suggestion I disabled 3g and started using 2g. It only increased battery life by 2 hours.

I also installed GSAM battery Monitor and looked at app sucker list. I find the following on battery usage:

Kernel: 10%

Launcher: 10%

Android system: 9.9%

Google Service: 9%

NFC service: 8% (NFC is actually disabled)

I don't know what is wrong with JB. These things never happened in ICS. Any help?
[Nexus S General] chronophase1:
I think its been stated in that thread it has nothing to do with GTalk. I've been signed in for days on end and Google services has never popped up on my battery list. I think it has to do just with a "phone home" of sorts to the Google servers or something.
[Nexus S General] Gambler_3:
Oh well my phone stanby is much less efficient now it seems, maybe it has to do with google now?
[Nexus S General] kurtgoedel:
Yeh, that NFC service does strange things. Two days ago I saw this thing using quite some juice even though it was disabled so i tried to enable it because I thought, who knows, maybe its not supposed to be off.. what followed was a complete breakdown, android system went bananas and suspend_backoff went up to 50%. After losing my isht because suspend_backoff reminded me of an older bug in ICS I rebooted the device and let NFC off. It didn't show up again, now its all pretty much ICS-like.

Stock OTA; just about 27 low-permission apps. I'm trying hard to stick with the defaults.

---------- Post added at 11:07 AM ---------- Previous post was at 10:51 AM ----------

Needless to say that I was superpissed when I saw that issuing dmesg as non-root no longer works on JB.. which makes it pretty much impossible to figure out what causes a suspend_backoff. :eek:

Security, you know.
[Nexus S General] praveenmarkandu:
Yesterday my battery life was really bad. But today I realized location reporting was on (for some reason). Turned that off today and it seems a lot better.
[Nexus S General] digitalsmoke:
"Android System"

My problem has been with the "Android System" draining the majority of my battery life. Sorry, I would post pictures to show you but I recently formatted the phone and lost them all.... DOH!. Anyway, through a day on ICS I would have about 4% drain from the "Android System" on JB I have about 35% to 40% drain from android system, sometimes surpassing even the display. Kind of Odd. I have tried the OTA, Jellybelly, and brainmasters JB builds and I've had the same results. Mind you for ICS I had all of my apps installed. With JB I tested it with no apps, with apps, with/without google now, location turned on/off, etc. and obtained a high "android system" drain either way. Just went back to slim ICS and "Android System" is currently at 4% with Android OS at 5%, where it should be :)

If your android system is unusually high, please post it so I don't feel like i'm going crazy :D
[Nexus S General] C4SCA:
Today i turned off the google location service and google now, lets see if my battery life gets any better
[Nexus S General] anshumandash:
Let us know if this has improved the battery life. Do you have 3g enabled all the time as well? Just asking to check. I have similar problems, with 3g on and google now on. Location service is disabled. However, I just found that there is another location service under maps/latitude which was still enabled. I have just disabled this new location service.
[Nexus S General] C4SCA:
i dont have 3g enable, i use wifi bcz there is hotspot in my city all over.

one thing i noticed is that for google now to work u need google location service (i disabled it and so i disabled google now too)

i disabled the app maps bez i dont use much and bcz it starts running by it self all the time!

i will update u at the end of the day

NEW LITTLE UPDATE!

for those who want to ask for things to google and it awnser with cards, i can tell that u dont need google now enabled.

i have now google now disabled and i still get those little cards.

so if u were only keeping google now enabled bcz of that (like me), now u know that u dont need to. Plus as we all know google now sucks all the juice of your battery.

second thing when u have google now enable, u need to activate google location services to get it to work. But if disable google now, u can disable that location service too bcz it dont need it to google search. even asking for my weather, it can guess where i am.
[Nexus S General] chronophase1:
I noticed that as well with the weather. Only thing it won't do is keep it the pull down tray
[Nexus S General] sacosta115:
Ya know it seems that even withy screen off ,and everything else off .except for sync I still get crappy battery life. With some use throughout the day like checking email or eBay periodically. now I bought the phone used and believe that the battery is still the original so gonna get a new battery in hopes of getting better life. Any advice on tweeks to system to get better life for now?

LITTLE UPDATE ABOUT BATTERY DRAIN:

Disabling all location services and google now is the key to let your phone go to idle, if not your phone will be always awake
[Nexus S General] alexcinci:
google no and little cards

Ola Cascabreu,

Tell me something, is your language and all the ins and outs regarding language is set to portugues or english?

Personally didn´t like how now works. Waste tons of battery, and lead people to put more and more of your life on google hands...

I disabled all that stuff, but I noticed that the search, even without now, works better but is heavier.

Finally, as said, I disabled google now but no little cards for me... Any ideas? My language is all set to portuguese...

PS:i9020T stock unrooted
[Nexus S General] chronophase1:
Have you posted in the kernel thread? That's where you should start if problems like that crop up with a new kernel. Also, thanks for that info on network services. Like I was saying, just the GPS enabled won't do anything since its only used when using an application. The other one fires off for whatever service requests it, even during idle. So it's very likely that activated plus Google Now and what it needs to function properly were causing that issue.
[Nexus S General] EleventhHour2139:
I really hope it isn't. Why in the name of God would Google make one of the main selling points of JB a battery hog to the point that we have to cripple it in order to get "decent" battery life?

i've had pretty good battery life since i updated to jelly bean but today it has been pretty bad and like you android os is the one that sits on top, the keep awake stats are only an hour short of the battery uptime. i've done nothing different on the phone and am a bit perplexed as to why the keep awake time has risen so much from the other days. going to turn off the location services to see if it makes a difference
[Nexus S General] dEris:
People, you do not need to turn off GPS. It's only on when something requires it like maps or location services like in Facebook. It's not on all the time like Wifi if it's enabled.
