How to save battery on nexus S

Hello there..
i just rooted my nexus S 9020T..i flashed CyanogenMod-7-08312011-NIGHTLY-NS,Build number GRJ90,Android version 2.3.5
my problem is the battery keep draining faster..
fully charged at 7.00AM..10% at 4.00PM
i using Juice defender ultimate (said longer my battery 1.5x)
please help me...

Juice defender is a waste IMO. You could try an undervolted kernel like matr1x or Trinity.

I suggest teuv kernel by Trinity, best battery life I've seen.
The nexus is a battery hog, especially with all kinds of background apps people have like whatsapp and facebook. If you get Trinity, follow instructions and you wont news any outside monitoring app as the kernel is very good about ram and CPU allotment

Nexus S is hardly a battery hog.

There are numerous ways to increase battery life. Firstly, you(Android) do not need battery apps and task managers/killers.
Secondly, try this.

Flash through recovery. Make a backup first. Choose the correct kernel for your device. Disclaimer: I'm not responsible for your flashing mistakes.

any other tips how to save battery longer??

Any further tips after a new kernel and rom would be cutting on the use of the phone and are therefore meh. I want to use the phone, not use it less.

So Trinity is better than Netarchy???, what about Pete #5 which is built in Formels MIUI, so far this is the best Rom I have tried on my NS, stable and fast+good battery compared to the others, also I have my phone OC at 1.2G via Setcpu.

Set wifi sleep policy to never.
Turn off auto brightness
Turn off sync and just refresh your gmail manually when you need to and refresh your contacts from time to time. You still get app updates from the market with sync turned off.
Go through all your apps that update regularly (facespace, twitter etc.) and reduce the sync frequency to something that is acceptable for you. I don't need my twitter updating every 15 minutes and can just manually sync whenever I want.
EDIT: Turn off NFC.
... and buy one or two of these: http://www.amazon.com/Samsung-1440m...TUEW/ref=sr_1_1?ie=UTF8&qid=1316132022&sr=8-1
Make sure to condition them properly - it really makes a difference.

Wifi Sleep Policy to never fixed alot of my battery issues

Turning off NFC will do nothing as NFC does only consume power (like GPS) when used.

PROTIP: Stop using the phone so much. None of these tips are going to do squat if you're using the screen and wifi/3G all day.
Trust me on this. I easily get 12+ hours of use with battery to spare (usually around 30-40%) with the following usage:
NOTE: Matr1x Kernel with the stock undervolting settings, and TSM Pool Party ROM running on top.
The screen is on (a little over 1/4 brightness) with wifi/3g blasting, surfing bright white web pages for about 2-3 hours total. I may play 30 minutes of Furious Neornithes D), screw around on the market for a few minutes, check FB updates, etc. I also probably take/make about 10 short phone calls and send/receive about 50 texts. The remaining time, the phone sits in standby.
Not bad, considering the phone is beefier than most home computers from 10 years ago. Also worth noting: The battery scale isn't the most accurate thing in the world. Battery percentage drops off sharply up until about 60%, where it seems to level off.

So what's the best kernel to use???, Trinity or Trinity UV?, Netarchy?, Matrix?, is not only about the battery but also stability, doesn't matter if u can make ur phone last forever if u can't use BT while browsing cause the thing crashes so u either have to use one or the other.

As this is the save battery thread, there's only one answer: lowest voltage trinity kernel.

No more battery woes

One of my biggest woes ever since i switched to gb was battery. I have been tirelessly searching for the best performance +battery rom out there. While i do value battery life,i dont wanna compromise on perf! I have tried out almost all stock based,i9000 based roms,cm7,n many releases of miui.cm7 n miui are the best performers out there for obvious reasons.but I really like the customizations of miui, n so tend to stick with miui more. Battery life is pretty good on galnet miui stable editions, but nowhere as good as froyo! But galnet,combined with a battery saving app green power, just works wonders 4 me! This is not a flame thread,nor fanboyism,just some knowledge sharing.
check this out, my best battery setup yet.
daily use rom- galnet miui stable 2.9.23 +glitch 12b3 smartass gov. +kg3 modem. battery lasting for 21 hours.
cell standby- very poor,~15-18%no signal,inside factory. this accounts for 50%of my battery drain.
display- 1.5hrs,
no wifi,3g on the whole time,but data controlled by green power.
call around 20mins, gaming around 20 mins,online videos ~15-20 mins.
some texting
oc to 1.2g +heavy uv using glitch 12b3.
Screenshots below.
Ps-if instead of 3g,I switch to 2g the whole time,I still have ~30%left by now.
if I am in a good signal area, this rom will easily last me 1.5 days. kudos to both green power n galnet.
EDIT: Actually, screen on time may have been more along the lines of 2hrs, looking at the battery monitor graph. i cant read from miui standard battery history because i had 2 restart my phone once, so it doesnt show correct unplugged times.

wherecan I find this green power app you speak of?

MIUI 1.10.14, NEO 17r18 with v51 script set to smartass/powersave, OC to 1200 mhz. No apps that disable network connections (think Juice Defender).

That's not bad for light to moderate use. I think mines not bad for moderate to heavy use.

Im on andromeda 3 again after flashing nearly ever custom rom in the past months including gingerbread roms. I still think andromeda 3 has the best battery.
Edit: Just my opinion of course.

Froyo ftw

Wow, the battery usage varies greatly between different people and their respective usage.
I've only used 3 ROMs: stock Rogers 2.2, Firefly 3.0, and Apex 10.1. My best battery life was with Rogers 2.2 but the ROM was lacking such as no working BT dialing. Firefly 3.0 was great and then Gingerbread came out. Now on Apex 10.1, I am getting only mediocre battery life. I can last 24 hours after light to moderate use only, but the screen was on for about 3 hours.

I'm on miui, oc'd to 1400, small uv, I'm consistently 18+ hrs, screen time in the 2 1/2 hr range. More than enough to get me through a day. Not that I care, I've got a car adapter if I need it. I would never go back to a ****ty samsung rom after experiencing miui goodness. The ui is unsurpassed, and the speed is incredible. No more of this having to reboot and clear caches to prevent the lagging and overall crappiness from the other roms. Reflash the update once a week and good to go. Never been easier and I've never been happier. I'll look into this app tho as suggested.

Nexus S 4G Roms?

Hi, I've searched the forums a bit and every thread I saw relating to this topic was a bit outdated so I've decided to create a new one.
I recently got the Nexus S 4G and rooted it, I've been using Slim ICS and it seems to give me issues and the battery life is horrid. I'm wondering if some people can give me their opinions on the Roms/Kernels and set ups that have yielded the best performance and battery life. I don't use my phone for much but music, surfing the internet (very seldom) and texting/making calls.
Thank you everyone in advance.

I'm finding bugless beast to pretty damn good atm

I have had stability and battery issues with most ICS but AOKP and Matr1x are doing amazingly well on my device. Not one complaint since the switch.

Thank you guys for the input, I will check those out when I get off of work. Anyone else have any suggestions? I'll probably spend the next few days flashing and testing them out.

Codename Android coupled with air kernel is extremely stable and quick as any other ROM and battery life is good. Also it has a good amount of launcher and status bar customization.
If your looking for speed though, Apex is undoubtedly the quickest in terms of windows opening and closing.

I'll check out Codename as well. As for kernels and things like that, what is the best governor and kernel, or is that all dependent upon which ROM I'm using?
In terms of speed, stability and battery life; I'd rather have stability and battery life over speed if that makes any different. All 3 would be lovely but I'm more concerned with stability and battery life. If the phone won't stay on or stay charged it won't matter how fast it is.

Kernels do their own thing as far I know. I usually use noop with smartassv2 or wheatley. And as I mentioned before air kernel is REALLY nice and stable.
I've been using the predecessor of Apex because of 1.0.2 issues on my phone and its really quick just like apex because its basically the same and it doesn't really sacrifice battery life at all either. I would give it a go. Its bigxie 3.5 on his "all crespo4g builds" link in the original post

Hi,
I use the SLIM ICS Rom and Im getting awesome battery life....
Hmmm did you change anything on it?
Are you turning off the internet, wifi, gps and sync when not used?
Did you clear battery stats? This is normally best when you flash any ROM.
Or maybe a widget or app is doing the draining.
I would recommend reflashing it with the March 4th update just to make sure.
Good luck
SLIM ROM has great idle, and you can always use the battery saver mode... with this you can have the ROM turn off syn, wifi and data all by itself when screen is off... check it out

Wow, I'm a moron. I remembered seeing the Power Saver and always thought I had checked yes, I hadn't just the individual settings. I've now updated to 2.8 ICS Slim and I'm going to see how that goes.
Wondering if anyone else has had this issue after root, I have the voicemail icon (which I hate) but when I click it, it dials *86 and I get a wrong code message. What exactly can I do for one to check my voicemail and second get rid of that annoying icon?

Go into your call settings ... voicemail settings ... and change the stock *86 to your own mobile number.

Just make sure u tell the power saver mode what to do under the settings... the default may not be what u want....
RU using Google voice? If so the only reason u would change *86 to ur phone # would be to call sprint VM.... if ur using GV then it will automatically download to ur phone without using minutes to call regular voicemail
I was at 1st against GV but now it comes in quit handy like the original sprint VM ...
Go under GV settings and have the notifications set how u want them. U may have to go desktop version of GV to customize all the settings... just to make sure.

Juice Defender feedback vote needed

To all G2x community,
I am having problems with juice defender, to be more specific whenever I hang up from a phone call there is a delay in the hang up process, usually takes 5 to 10 seconds after I press end call. The issue is posted on the Juice Defender feedback forum, and I just wanted to call on you guys to pump up the vote tally for this issue. So if you can, just click on the link and give it the max 3 votes I'd appreciate it.
http://feedback.latedroid.com/forum...ns/2257272-no-data-connection-while-on-phone-

Edit: Whoops.

I get the same problem, I also have a problem with WiFi calling constantly polling my phone as traffic even with WiFi disabled with the phone set as WiFi Calling on Enable/Screen Off.

I always wondered why there was a delay on hangup... Never knew it was a JD thing though. Hope they address it quickly

I don't use these types of apps, but a while back I noticed a new similar app in the market. I'm curious as to how it compares to Juice Defender, has anyone tried it? It's called Go Power Master (by the same devs who made GoSMS and Go Keyboard etc.)
Sorry if this is a thread hijack

Looks like the same idea... I may give it a shot as I use go launcher already and like their products (some of them)
Edit: That app is nowhere close to as customizable as juice defender and its ui is really ugly hahaa defiantly sticking with jd
Pin it to Win it.

Are you using a specific rom or just stock? I have ran into this issue with or without jd on certain roms (can't recall exactly such ones atm) but it may be a conflict also. I run jd on tsugi right now and use the 2g/3g since it still doesn't work radio wise with that version. But I have jd ultimate for the wifi capabilities, and have on all other roms for the past year and a half.
I have used certain roms along with certain kertain kernals without jd and had that issue though. I understand when its disabled things goto normal, so I guess are you running froyo, gb, 2.3.7 or ics?

I'm running Weapon G2x 3.0_R1 ROM with the stock kernel and using Juice Defender Plus.

I'm running stock firmware non-rooted with JD plus and getting delayed hangup.

JD is pointless, all it does is turn off data when the screen turns off and on when the screen is on. This can be done by the touch of a button easy.

Thing is i WANT the data to stay on even during screen off, its not like i have a lot of traffic going on 24/7 anyways, its gonna update stuff like facebook, messenger, email twitter etc only, which uses very little traffic anyways.
I tried to set it updating everything whenever i turn screen on and all it did was cause some minor lag whenever i unlock screen.....not a very good idea to me lol
And to the OP, juice defender actually made my battery WORSE.......it kept trying to close some background stuff for me and ended up using a lot more power than it should be. All you need to do is flash a better rom/kernel, underclock (and undervolt if your hardware allows it, mine doesnt but its good enough so it is fine on stock voltage underclocked).
I did a test recenly, exactly 20 hours and my battery stayed at 97% with very little activity, which I consider as very nice. The next day I used my pone for about an hour on talking, roughly 30minutes on games, and probably an hour for web browsing, and i still have 59% left at the end of the day
Regular battery too, i did not buy a powerful battery replacement.
So yeah SCREW JUICE DEFENDER!!!!

If you wanted data to stay on all the time, JD is completely useless to you. Seriously.
Sent from my amazing G2x running EaglesBlood and Faux.

I've used JD Plus for well over a year. I'm really starting to think the app is hype. I see no major difference with it or with out it. Pointless.

If you read back some threads before on JD, you would find out that JD off the market (at least it still is) does not work on the G2X for some reason. You have to install a beta version of it that was linked on these forums a while back and use that.
The market version was not able to shut off data at all whereas the beta version does.
I was able to get about 27 hours before my battery depleted just on a new ROM and not having to UV/OC any settings. I still use it on my GB ROMs. Doesn't really work on the ICS ROMs.

I have had it for a long time, and noticed quite a bit of difference compared to without it. GB did change that until the beta. And with ics, it does work for me. I use it for the data shutoff + automated wifi enable/ disable. If I really need an email that I'm waiting for and can't miss that extra 5 min of duration that it takes, I turn it off. That's where I notice the major difference, especially with the newer kernels for ics builds. But obviously it doesn't seem to work as well for some people, or some people just don't like it. That's why theirs different versions of everything.

I'm giving this thing the bump!... I'm impressed with the votes, the vote total is in triple digits. We need some more votes to get this thing pushed through. It's the only thing that bugs me about JD right now, and I'm sure there are alot of people in the same boat.
http://feedback.latedroid.com/forum...ns/2257272-no-data-connection-while-on-phone-

Don't use it, it doesn't help.
For me the battery life on my settings was so good it decreased it due to my phone being woken up every 30 minutes.
This is my battery life on stock battery without JD

With JD I probably would've only gotten 18 hours.

I don't know if JD does drain battery a lot or not. But I always have trouble with it connecting to Mobile Data quickly. I unlock the screen, it shows the 4g icon plus the four white bars, but it's usually connected only when the bars turn blue. And it takes forever for the bars to turn blue, like a 10 second delay, any way to fix it?

[Q] Higher battery drain with Wifi off?

I've noticed with at least my Infuse that whenever I have my Wifi on I have significantly lower battery drain than when I have it off. I'm currently running Aeon 1.4 with Entropy's kernel but have noticed this with other kernels and ROMs that I've used. Screenshot attached showing that pretty much as soon as the wireless is turned off the battery usage takes a sudden drop and continues until it comes back on. Is there an issue with my phone or are there some settings that I should be aware of and try changing to remedy the issue?
I tried searching around before I made this thread and couldn't find anything that had the same issues I've been having. Any input would be appreciated.

I see what you are talking about, however I think the issue is less with your wifi being off as it is with your cell signal being low. Looking at the cap you provided I can see where in the second wifi off period you could think that the wifi was your problem, but look at the first. you have the same drain with the wifi off as you do with it turned on (practically). Change the modem. Find one that works great in your area, because with the modems for the infuse newer is not always better. Also you can try one of those little RF booster things that go on your phone behind the battery to boost signal. I know they seem like a scam, but they do sometimes give just enough boost to keep a phone from searching for signal when it should have great signal. But try flashing a new modem first.

Looking at the cap you provided I can see where in the second wifi off period you could think that the wifi was your problem, but look at the first. you have the same drain with the wifi off as you do with it turned on (practically). Change the modem. Find one that works great in your area, because with the modems for the infuse newer is not always better. Also you can try one of those little RF booster things that go on your phone behind the battery to boost signal. I know they seem like a scam, but they do sometimes give just enough boost to keep a phone from searching for signal when it should have great signal. But try flashing a new modem first.

I'll have to start looking around for a new modem, currently I'm on UCLB3; my only concern is this is the only modem to provide me with a quick GPS lock and I don't want to lose that ability. Thanks for the suggestion

Check the modem thread. I had some great luck with an older one (k1 I think it was). I have since passed on my infuse to my son, and I can ping his location within 15 yards in under 2 minutes. I have a post over there where I got 5 days of battery life and it should tell you the modem I was using as well as rom and other info about the setup I had.

I found it for you, it was in the battery tips and tricks thread, buried away.

I also added a picture of your screenshot to my original post here so you can see where the wifi and the signal are at more accurately on the battery meter.

Thanks for the link, I'm actually using ADW Launcher Ex right now and by the looks of it I shouldn't. Though I don't think I'm ready to spend the money on esf shell; are there any other recommendations for launchers that aren't as much of battery hogs?

If you have an ics based rom apex is nice. Launcher pro plus for gb is good IF you don't use the LPP included widgets.

Giving FTL Launcher Lite a shot, if it doesn't work out or if it's not recommended I'll try out Launcher Pro, thanks again!

I tried it for a couple days, was not my cup of tea. But it had outstanding reviews so I gave it a shot. I think I ended up going to LPP or ADW with the infuse.
A few other things to check are: Make sure your phone is not always scanning for wifi networks.
If you are in an area of low cell signal and don't need your phone to call people, flip on airplane mode.
Turn off auto brightness... use the power widget (or the 17 notification toggle tweak) to change your brightness between 10% (low light) 20% (medium light) and full (when in bright daylight conditions).
There is somewhere a tweak to turn off H+ and 3G when not in those service areas, find it, use it. (Google *#*#4636#*#* or is it *#*#3646#*#*... idfk one of those...
Check your sns sync schedule for short times. Set them to a longer interval or off. You should check ALL sync schedules for this, calendar is a major culprit of this, even if you don't have one setup.
Install "badass battery monitor" use it to check wake locks and battery voltage and temp. It has a great "battery sucker" feature that will tell you what is draining your battery.
NEVER USE AUTO APP KILLERS! They do more harm than good. Hold home and open the task manager and kill the apps yourself. It will take 15 seconds and if you do it for 3 days a few times a day, it becomes a habit. Don't be all grrr and do it 60000000 times a day. Just every now and then.
If you have installed a few apps and launchers that didn't work out for you, I would say booting into recovery and clearing the cache or a reset are in order. Uninstalls rarely remove everything they should and leave behind bits of code that will suck your battery like a hidden mosquito you can never swat.
Probably the most helpful tidbit anyone can give you is to not stress over the battery life constantly. You have a wonderful device that you have spent a lot of time customizing to look the way you want it to look. The more you stress over the battery the more you will check it, turning on that big beautiful screen sucking even more life from it. Making user error the major battery sucker in the equation... You wanted that beautiful beast, enjoy it.
Sorry so long, but trying to be thorough and helpful. These are the major tips I used to get 5 days from my phone. But honestly after day 2 or 3 I started really cracking the whip and refused to use my phone for anything other than texting.

Looking around I can't seem to find this, does it just disable all data when there's no service? Sounds great if it does.

No it just drops you down to edge.

Its been about the same, possibly a bit better. I've been using the battery app you mentioned to find what's causing the drain and kinda working with it from there. However I was in an area with roaming for a week so I can't give an accurate conclusion.

The BCM4330's standby drain is extremely low. In addition, when active, it requires FAR less energy per byte of data transferred than the cell radio.
OF COURSE background syncs are going to use less power over wifi than over the cell radio.
The whole "turn your wifi off" to save power became invalid over a year ago. (Exception: If the wifi chip misbehaves, such as the infamous BT-AMP bug, but I haven't seen that in many months.)

Here a couple of threads I found regarding this mystery drain.
From the past:

Here is the i9000 battery drain issue I was refering to:
http://forum.xda-developers.com/showthread.php?t=1039696
The last few pages hinted that the problem may have been fixed in later gb builds.
Our custom kernels was based of Roger's 2.3.3.
Would the bug be still in it?
Could this be why we (at least me anyway) are still seeing this?
