my experience:
Rom: Cronos 1.7.2
Kernel: flykernel12a
max/min: 614/176
gps: sometimes: 3g sometimes.
battery time: 25 hours

25 hours from 100% to 0%?
My restricted use: phone calls about 1.30 hr a day, about 100 sms a day, very little (20 mins max) of browsing, and ultimatejuice+juicedefender running for notifications, i get about 37 hours of use.
I ordered a Mugen 1550mAh battery, which is on its way, and waiting to test that out.
In a perfect world the Mugen battery with moderate use would last 2 days off the charger (charging every other night)

Nice topic!

I saw the review of that Mugen 1550 mAh, you just get 3 h longer battery life.
With 3200 mAh the results are 3×standard 1350 mAh battery life.

Rom Floyo 1.2.0
Flykernel 12a 614/176
And concerning the Mugen Battery, well they say 3 hours but considering the wear on this already year old battery (which is about 30% less than what it used to be when i first purchased), i am expecting a 5-6 hour gain. At least, those are my hopes
edit. kernel info forgotten, twice! sorry ^^

yea, it's amazing. but won't run juice defender so I just turn off data updates overnight and my battery stays basically where it was until klaxon wakes me up, then I enable data updates again and go for another day.
I could use a new battery, but aside from that I get more time from this rom than any other.

There seems to be a few small things that need resolving DK, but I am glad Elelinux is helping out as well now. Very different build styles but same goal. Feeyo took it down to the essentials, its very light. Just need Erasmux out of retirement now
I have 3d issues so might try reinstall as others don't get this. Fee usually finishes a new build while you download the most recent one! With Ele on board we might get 3 dl's a week!

3g: Always enabled
Wifi: Enabled if in range of wifi ive used before.
Auto sync on (juice defender and ultimate juice syncs every 30mins)

Currently average between 36 and 39hours.
On Feeyos older 2.1 roms I used to get a full 3 days but kept it on 2g only, standard clock speed, and disabled tilt sensors.
(Edit- In case you can't tell, Im a battery snob lol. If an app is using too much battery I get rid and find an alternative I also only have 44apps installed )

Update your ROM dude! The new Froyd or Floyo (my favorite), either one with the newest Flykernel, will greatly improve battery life and performance. It's worth spending the time doing it.

Nice..
Mine can only hold for about 15 hours, lite web browsing, barely phone calls and texts..

I got about 16 hours yesterday. Using CM7. Brightness all the way up. Everything on except wifi. Browsing about 2 hours. About 5 phone calls, 15 mins or more. Used google maps. Did about 20 text msgs. I think that's all I did. Loving the battery life on CM7.

I get like 2 days use out of my phone without charging it. I've always tried to figure out why my battery life is always so much better than my gfs and I think I might have figured it out....I'm always on wifi.
The two places I am the majority of the day (work and home) I am constantly connected to wifi so it keeps my radio from scanning for a bettery data signal so my battery lasts a lot longer.

I have:
Iced Glacier v.1.1.6
Gorilla OC 1.6ghz beta v05 (but runs at 1.7ghz?)
SetCPU set at 1.7ghz ondemand and 245mhz screen off powersave
I get around 16 hours from a full charge, but Im always on the phone and playing with it but I have noticed that my battery does last longer on wifi

after tinkering around with it its working out better.
using
CM7nightlies#9
CM kernel
no setcpu
i get around 20 to almost 24 hours of usage. but most of the time i'm charging or partial charge cause i stream music like a mad man ahha.

stock i can get almost 24 hrs on a full charge im also using screen filter app(awesome app to use) im on pocket empires a lot too

Is it just me or does 100% last longer when fully charged? Has anyone also observed this? ATM I have 93% at 20hour mCPU scaled at 768mhz and around 15-16H moderate use with scale at 1.6GHz on max load.

I bought the Mytouch 4g on black Friday and found problems with the battery life in the first week. 5 Hours maximum without even using it. The camera worked randomly. I exchanged the phone for another one and all my problems were solved. I use the phone for gaming mostly and that drains the battery obviously .
I purchsed the powerskin case from the T-mobile store and I couldn't be more satisfied. I can use my phone for 6-7 hours straight playing games and browsing the web and it still has a full battery with a bar left on the power skin. It may be a little bulky but it brings be back to the good ol days when phones were bricks and adds that extra padding that I feel is necessary for protection. The price tag on the powerskin was $70 at the store but when it was scanned it came up as $40.00.
I highly suggest this product for those with fear of their phone dying unexpectedly.

Just because of root your battery is that great? My brightness is off all day and my Data is off and my battery MIGHT last me till like 10:00 PM..

This is probably a silly question, and after quite a while searching I haven't found any real answer, but here goes:
Going from original out-of-the-box to rooted RoyalGinger 2.1, the battery use by my Display has gone WAY down. Like from always being #1 to usually being well below Cell Standy, Phone Idle, Wi-Fi, etc. And it's definitely not that I'm using the Display less.
Has anyone else seen this? Does it have something to do with how RoyalGinger, Gingerbread, etc. calculate battery usage? Is it normal?

yes its normal. you came from stock MySense UI(stock Glacier), and Sense builds are known to be battery whores because they look awesome, have loads of interactive widgets, and lots of bloatware as well. going to an AOSP build(CM7, RG) the ROM is very lightweight and contains little to no bloatware and still as fast, maybe even faster. just look at the size of the files...Sense=300+MB, AOSP=80-110MB. plain and simple, all of the bloat consumes more power on your display

Thanks for the prompt reply. I guess I didn't expect the Sense bloat to be reflected in the display usage. Does "Display" include the touch interface as well? If so, I guess I can see why Sense would show up as display.

Display counts more than just the power used by the LED backlighting.
I plugged my phone in yesterday at 14 hours of uptime with 45% battery remaining, after a day of fairly heavy use. Close to three hours of music listening, two hours of screen-on time and 3G/wifi web browsing, forty minutes of voice calls and a few SMS.
Using CM7 nightly #143 and insanity v3 kernel, 122/1017 clocks with smartass governor. I'm sure if I switched from smartass to conservative my battery life would increase a bit, but I like the smoothness that smartass gives me, and even on a day of brutally heavy use, I'll still come home with at least a quarter charge left.

Here's mine. Don't post attention to the time, I rebooted a couple times, it's probably been about five hours on battery. I don't do too many games per se, but I do browse xda and facebook a lot

as you can see (er, read), the display is really low. not sure what's up with system (maybe scanning the sdcard?), usually it's just standby and idle at the top. this is on RG2.1 with the display on auto brightness with defaults.
so this really is normal?

yep, that looks about normal for AOSP builds

Well I won't complain. Like I mentioned, I was really surprised at the low battery consumption of the display. Didn't expect that much difference just by changing ROMs. Wish I would've rooted a long time ago.
Thanks again for humoring me and my silly questions.

Battery life

Sorry if this is a bumped thread, but how do I make my battery last longer? Mine lasts less than a day. It gets charged overnight and by 2:30 its got the yellow battery thing. That happened today and it was in my pocket not even being used
Sent from my Incredible using XDA App

Bigger battery. Basically turn off everything and you get better battery. Turn on 3g GPS wifi Bluetooth all that stuff and turn the screen brightness down.
Sent from my Incredible using XDA App

Not sure if it applies to you, but if your phone is constantly in poor signal areas, that is going to drain your battery a lot faster.
As mentioned, turning off features that you aren't currently using is a good step: GPS, Wi-Fi, etc. Some people will retort that these features shouldn't use much (if any) additional power when they aren't being directly used. This might be true if you have 100% awareness of how all of your apps are utilizing the phone's resources, but some people don't realize that their apps may be periodically using these features to gain more accurate location information (or otherwise doing things in the background).
Speaking of background processes, make sure that you don't have any rogue apps that sync too frequently. For example, some social networking apps may be using your background data far more frequently than you would care for them to. Check sync settings in suspect apps.
Most of all, just try to remain aware of how you are using your device. If you are playing Angry Birds constantly, it's going to drain your battery. Installing an app that will log power usage can be very educational (like CurrentWidget, for example).
Undervolted or underclocked kernels / cpu settings can also help a lot.
But if your phone is draining down to critical levels by mid-day, even when the phone has just been in your pocket, I would suspect apps/settings that are utilizing too many background resources.

Get on CM7 nightlies with the new .37 kernel and get 36hours of battery life like me and that's with normal use!

You may have a defective phone or battery. I'm currently in the same situation just a little worse. Basically 15 minutes after my phone is off the charger my battery falls to 80%, then it'll be to 50% a couple hours later. This is with zero use and in airplane mode for the majority of the time. So I have to plug my phone in at lunch for a couple hours, but that only gets it to about 85% at which point I can keep it in airplane mode and make it home by 5pm with 50% left again. I occasionally turn back on the radio to see if I have texts or voicemails.
They are in the process of sending me another battery, but I have a feeling it's actually the phone. If I monitor CPU usage in system panel there is high CPU usage while the radio is on, but in airplane mode there is very little. The only things really taking up much CPU is android.process.acore at 6.5%.
I have no idea what's going on, but I'll just be happy to make it at least 15 hours on a charge like I could with my Droid and Droid 2.

Here's my setup...
I get great battery life (70-80* hours from full charge to dead) with these settings:
ROM: SkyRaider 3.5
Kernel: Incredikernel
I'll echo another member's post. Turn things off that you aren't using (i.e. 3g, wifi). I will only turn these things on when in use (checking email, surfing web, etc). Along with 3g, and wifi, your screen brightness is a huge battery killer. I have mine set around 20%.
Another thing I found to help is having SetCPU profiles set. Here are my settings:
main: 1075 max, 245 min. ondemand (set on boot checked)
screen off: 245 max, 128 min. priority 100
Temp>39 C: 245 max, 128 min. priority 99
Charging/Full: 1075 max, 245 min. priority 98
Battery < 20% 883 max, 245 min priority 97
Battery < 40% 998 max, 245 min priority 96
The above settings give me outstanding performance while the phone is in use, and really help to save battery power when not in use.
*This battery life was directly after a wipe of the battery stats. After a few weeks of regular use I'm seeing about 60-70 hours of life (full charge > dead).

yeah, I would have to say that your poor battery life is a combination of the stock kernel and the stock sense UI, which both suck up battery like nobody's business. When I used the stock ROM and kernel, I got like 6 hours of battery life. Now, same phone, battery, everything, i get like atleast 20, more if I don't use the internet much or text all day.

yes, stock battery. These stats were directly after a battery wipe. I've gone through lots of battery cycles (full charge > dead) since than. I'm now getting 60-70 hours per charge.
I've edited my above post with updated SetCPU settings and denoted the battery wipe.

I second this. I get amazing battery life (~1% every hour) but that's with:
- screen off
- using the HTC extended battery - 2150mAh
- without bump charging [see: http://forum.xda-developers.com/showthread.php?t=871051]
- I also don't worry about 3G, GPS, or location and leave them on all the time (but I keep wifi off when not using it).
But the above setup is excellent for battery life compared to dozens of other ROM's and Kernels I've tried.
The 25plus is what I'm using, the other one had a few issues but still overall ran pretty solid.
setCPU usually isn't recommended with this kernel because it already has one built in but I never experimented much with this so I don't have anything to really say about it.

yeah i didn't do any music streaming from subsonic that day, but even when I do (about 2 hours worth) i still get at least a full 24 hour use period out of it.

My battery life is alright i guess. One thing that worries me is the huge drop I get right after i charge it to a full charge. It drops about 7-10 percent within minutes. After that its slows down.

It's normal because your phone is really suppose to use 80% (top 10% and bottom percent unused).
You can bypass the top 10% by bump-charging, but you will decrease overall battery life.

I went all day without charging running the new trigger rom.

Just wanted to recommend the trigger rom to everybody with bad battery problems. I was running Bionix before and getting 8 hrs at most, but now with trigger Im going all day without even touching a charger. I dont have any widgets that connect to my internet on the homescreen and Im not running any apps that hog power. Yesterday was a pretty heavy day for the phone though ant it worked flawlessly. I guess the only thing I really did was underclock it to 800mhz.

I am running the Bionix 1.3.1 with the Dragon overclock kernel. I get 15-17hours a day on one charge, I am overclocked to 1.28ghz (I do have profiles in setcpu that underclocks me to 800mhz when the screen is off or when I am charging its down to 1ghz).
So I am not bashing your rom, but the reason you were having such terrible battery life really doesn't have much to do with Bionix. When I was running Bionix by itself I was averaging 22hours on a single charge
Currently I am at 30% battery life having gone 9.5hours on one charge today. This was a particularly harder day on the phone than normal, I have made several calls (to the tune of about 2 hours total), I have been playing "word with friends", constantly chatting on google talk, updated several apps over the course of the day, did some google searches on Dolphin HD browser, some you-tubing, and constantly checking and reading/replying to emails from my three accounts that are synced on it.
(I was home all day today lol)

Impossible to really put much into it. Everyone uses their phone differently, even those people on different days. Flash what you love.

I get two days worth of battery life with heavy texting and moderate wifi. This Rom is a keeper for me I'm at 1 day and 3 hours and got 45% battery remaining.

I get from the Trigger Rom 20 hrs +/- with average use , 30 calls 20 texts, 20-40 emails, music other misc.
it is a Solid Rom and it battery performance is excellent.

Trigger + Tigersblood = Winning

nothing new...
Overstock+any rom with disabled 3g and setcpu @800 MHz - about 48 hours (with music, ebook, calls). The proof is somewhere in the Trigger topic

I just went 29 hours off one charge on mine. Trigger is a keeper for me as well.

Get the same battery life with bionix 1.3.1 and overstock 1.5
3 exch accounts
Facebook and twitter syncing every 2 hours
3g+wifi
Two hours of bluetooth and music
Few texts and phone calls
Gps for traffic in the morning and in the afternoon
Brightness at 50 %

And here I thought I was finally doing good with Trigger and you all come in and blow my happiness out of the water.
I pull mine off at 8am sharp, it sets with wifi and wifi calling on at work all day. maybe 1 10min phone call 2-4 txt and 4-8 emails and I get home at 6pm with 20% remaining. before on stock I would have to charge at 1-2 just to make it home and I thought that trigger and overstock was kicking butt till you all stepped in here with your usage and times and now I'm depressed again....
I even installed system monitor and it shows wifi calling only using 2-4% all day and the cpu usually hangs around 200-400. Guess my phone just hates batteries. might try setcpu.

trigger is awesome. i was messing around with some of the 2.2.1 roms... but i eventually went back to trigger. so smooth, so clean.

Wifi calling is a huge battery drain. You'll do much better without it.

The only issue is no signal at all at work, so wifi calling was a blessing when it came out so giving it up is kinda a bad thing, nothing like paying for service I don't have 9 hours out of the day. but like I said wifi calling was only consuming 2-4% so I don't see how that is killing my battery. But for a test I'll run one day with the app frozen and see how my battery goes.

I don't think the 2-4% is completely accurate, as that's probably due to cpu and not the increase in radio/standby usage. Try it without when you're not working. Even so you're getting great battery life for being on wifi calling.

Im not bashing the Bionix rom at all. I ran it for about 3 months straight and it was amazing. I had it overclocked to 1.4mhz and it was a beast, but I never used all that speed anyway. I was constantly disabling data and I basically took all the smart out of the smartphone. I was having to do everything manually to keep my battery lasting about 8 hrs.
I just never had battery life before like I have with this trigger rom. I just wanted to recommend it to other people that have serious battery issues. Flash whatever you want. The people on these forums have ceated some amazing roms and they all have their pros and cons. For me, trigger is the best so far. Just wanted to put that out there

Do you have a desk job where you sit at a computer? If you do, why not just hook your phone up to your computer with the USB cable and let it charge and power off of that?
But as was stated before, Wifi calling along with really low or no signal will eat your battery.

Odin back to stock then flashing trigger again helped my battery big time also.

How much battery life should I be getting on my i9020a (ICS 4.0.4)

Even before upgrading to the official 4.0.4 build for my AT&T Nexus S, I was starting to feel like my battery life was diminishing over time. After applying the update, it seems like the battery drains even faster.
It seems to hold its position pretty well when idle, but whenever I'm just browsing the web or anything it seems to drop by about 1% every 2-5 minutes or so. Is it just me, or is that excessive?
I have read a lot about resetting your battery stats via Factory Restore in order to regain the battery life that the Nexus S had when I first got the phone, but I want to know whether or not that's actually necessary.
I guess what I'm asking is this: How much battery life do other Nexus S owners running on ICS get on an average day of usage (little web browsing here and there, maybe 30 minutes of talk time per day... etc.)?
Once the end of the day rolls around, I'll take a snapshot of my battery stats and upload it to this thread. Would any of you mind sharing yours as well?

I'm noticing an unusual discharge from the battery (i9020A unlocked), I always took off the charger around 7:30 am and 12:00 am for always had more than 70% of battery with Gingerbread. Now with 42% with ICS at 12:12pm . Now I finish writing this (12:44pm), now I have 39%

Yeah, that might even be worse than my current battery life.
Can anyone attest to the effectiveness of doing a factory restore to reset the battery stats? I've heard that this can sometimes fix the problem. Supposedly the stats can get screwed up and start reporting that your battery is 95% charged when it's actually 80% of the battery's capacity, resulting in quickly depleting battery life.
Any truth to that claim?

If you are willing to do a restore, then why not root it? Flash a custom ROM and kernel. I get 14 hours of battery life easy one 4.0.4 using CM9 and Matr1x kernel!

1% per 2/5 minutes is actually really good. Especially if you are using it heavily..... I'm curious just how much better 4.0.4 is with battery though...

I'd like to stick with the official ROM rather than rooting at the moment. I know that's close to blasphemy around here, but I'd rather not mess around with a custom ROM/kernel right now.
That being said, I'm pretty sure my phone lasts 14+ hours on average. Is that good, though? That seems pretty sub-par to me. But this is why I made this thread: to find out what kind of battery life is normal/acceptable for the Nexus S.
I have attached some current screenshots from my phone:
I unplugged it at 6:20 this morning, and it's now at 43 percent about 7 hours later. The sharp drops you see on the graph are my morning and lunch-time web browsing. The more stable portion is just me at work with the phone mostly idling.

A lot of that drain you're seeing can easily be explained.
Notice how your signal hasn't been great. If you're signal is low bars it takes more power connecting and all of that (to be really blunt about it). Next time you test the battery, try it in a place where you get good signal (not school ;p).
My last major test I had my phone on for 1 day, 16 hours, 3 hours on-screen. The other day I decided to just burn through the phone, I got about 5 hours of on-screen time. It really depends how you use the phone.
Also the kernel, governor, and scheduler also effect the battery. So mess around with some kernels and settings.

Yes along with signal how long you have had your nexus could be too.
These little batteries go through a lot and after time they don't perform to like they used to. Along with troubleshooting your battery drain and look for a oem battery to replace your old one

I think I've had my phone for about a year now. Would that be long enough to necessitate replacing the battery?
Is my battery life even particularly bad, or am I just expecting too much from my phone?
Edit: Okay, now I am at 35%, Down 10% from less than an hour ago, and all I have done is send and receive a few texts.

Your battery stats do look kinda bad. What's your screen on and voice call time? I'm on latest BB with simple kernel and my battery is pretty good with 4.04.

Why is the screen using up so much power?!
The idle power drain is perfectly good, but look at the steep parts on the graph where I have had the screen on!

Having the same problem after ICS. Its been 3 months I bought a new phone i9020a

How much screen time are you expecting to get? 3-4 is usually the norm for a full charge and about an hour's worth of voice calls.

If you let your battery completely drain occasionally it re-calibrates the battery software. Over time the accuracy of battery stats degrades. Letting it completely drain will then give you a more accurate reading.
Lithium batteries don't like being completely drained on a regular basis, but done occasionlly has no real effect.

depends I would also try a new battery from a good supplier, it could be the one thing that it needs. No your battery life is bad, I demand alot out of my phone and bite the bullet and got a mugen extended battery and its awesome I can literally stream panadora off 3g all day at work

Ok, looked at your pics. Something is definitely wrong there. Here's mine for a reference. I'd give it a few days, and if it doesn't improve, it may be time for a new battery. You could try calibrating, but I've never had to. It usually will work itself out after a few charges.

This is mine after the first flash. Not ttoo bad considering I used it an awful lot. I think the OS needs a few charge cycles from what I've read to calibrate itself. I don't know how true it is though. I've found a ROM to use as a daily driver so I'll see what my usage graph looks like in a few more days. If you do need a new battery, eBay has OEM replacements for 5 bucks.

That is very poor. Maybe try not using boat browser it seems to be using a large amount of battery

In 4.0.4 the CPU min is set to 200mhz instead of the usual 100mhz. Well everything gets snappier and faster but its normal for your Battery to drain faster. I recommend using a custom Kernel so you can change your CPU min to 100mhz. And try using as much black as possible on your phone if you are using an Amoled Screen this saves you a whole lot of power. I for example use inverted apps and the blue infinitum theme and a black wallpaper and this gets me another screen on hour.
I even use the browser in the inverted mode. If your using the "Quick ICS Browser (Stock Browser with extras)" you can simply turn off the inverted mode through the quick controls if you want to watch a picture. Believe me once used you'll never want another Browser! Here is a pic of the inverted mode.
Almost everything is dark and the black parts nearly don't consume any energy and the other picture is showing the quick controls you get when you slide the boarder of your screen.

I don't get why all the Google Apps are still in friggin' white. They would look so much better in black.
