Battery - up 'n running for

...4 hours of heavy usage (wifi connection and 3g on but idle)
Mid to periodical usage could reach 24h.
6th day of usage....
i think this is mediocre for me. please report your battery performance to compare.
Any tips to improve this?

I can get around 8-10 hours with heavy usage... constant music, etc.. and about 2-3 days with light-medium usage.

Hmm so i guess there is a problem with my device.
Great!, and how am i supposed to explain this to the service?

I get about 12 to 15 hours of heavy usage via web, text, and email. If i watch video it's less but I am pretty happy with the battery thus far.

I can only get around 7 hours of use.
I have a problem that if i even dont use it, the battery still drain. I got it full charged and theb unplug it. About 8 hours later, it went down to 50%.
Is there any problem with my device?

same here. i don't know how you guys are getting so much better battery life. i can barely last a day and i don't use it all that much. maybe 2-3 hrs of surfing the web over wifi (not even 3g). i even used setcpu to underclock to 200Mhz when screen is off.

Maybe it has something to do with the very first charge.
When i unboxed the battery was fully charged so i drained it and had it charged for 8 hours. maybe it needed to be charged prior first usage.

Is that 12-15 hours with the screen on? Because that's much more than I'm seeing.
I've done a few measurements just to get an idea of the battery life. They are just extrapolations based on a few hours of runtime for each so they are by no means exact, but my impression is that they give a decent view of real values nonetheless. The battery percentage indicator does not seem to be terribly non-linear.
Video playing (SD quality) with full brightness: 5.5 hours
Video playing (SD quality) with lowest brightness: 9.5 hours
Idle at homescreen with full brightness: 6 hours
Idle at homescreen with half brightness: 9 hours
Idle at homescreen with lowest brightness: 12 hours
Music playing in headphones (screen off): 90 hours
Can't believe how lazy reviewers seem to be, I haven't read a single one where they have properly measured battery life for things like playing movies or reading an ebook. It's all just subjective feelings (which are obviously very unreliable).
All in all I am pretty pleased with the battery life (but I've just had it for a few days). I especially like the fact that it's basically a normal Android phone just with a giant screen and battery. This obviously means that standby and music playing times are going to be excellent.
Edit: Those of you who think you're seeing bad battery life, what does the battery use thingy in settings say? Or is that not a good tool?

I read a post somewhere where the OP was getting horrible battery life and found out that the Gallery app was draining the battery.
The OP in that thread said even exiting the app did not kill it, and it kept draining the battery.
Perhaps you can look into this more. I never use the gallery app so maybe why this is why i get decent battery life?
Edit to add:
Here is the thread
http://forum.xda-developers.com/showthread.php?t=826472&highlight=gallery

If it's this post you're referring to it's by me . The Gallery application shows up under battery use though, so I'm pretty sure that's not it.
Are you sure it's really as much as 12-15 hours with the screen always on? If it were 9-10 hours with brightness at half it would around what I'm seeing I guess, but 12-15 is quite a lot more. Not that I'm disappointed, but if better is possible better is what I want

No not 12-15 hours with the screen always on.... I get 12-15 total... Screen on for usage, off for a while, back on to email and SMS ect...

Ah ok, then there's no discrepancy .

I got 10 hours from full to complete off. I was using it to watch streaming movies on 3g
for a couple of hours and then watch a movie off of the sd card and an episode of supernatural.
After that its just web and ebook reading. Its pretty good. Almost the same as my ipad.

I got a total of around 14 hrs plus with wifi and edge on, screen brightness at 20%, around 7 hrs of standby while i was asleep at night, with 4 hrs of heavy surfing, youtube etc. . . No calls though, only some sms and always on IM with nimbuzz logged in.
What i am seeing is with heavy usage i.e. Multiple apps running, wifi and edge on, i get anywhere between 5-7 hrs of battery life which i think is fair enough for a device this size which am constantly fiddling with.

Can someone please post,
Using the supplied mains charger, how long does it take to fully re-charge a drained Galaxy Tab?
As it is a large battery what sort of charging times to expect?
(This is while NOT using the device).

I've not used mine for that long, but the Battery Left app(which I found to be quite accurate on my N1) shows that for MY usage, I'll get about 25hrs.
I've got the auto dim turned off, and brightness at max. I mainly use mine for checking emails, txting, and a few games.
Nothing heavy.
I'd recomend the Battery Left app to you guys looking to find out your battery life. You DO have to "train" it though, which requires a 100%-0% run for you.

Guys,
does.anyone know, do we need to cycle the battery to give it the best performance?
Example, charge up the unit, then drain it completely and recharge it again? Like in the old days.
mine hasnt gone down much. I have it unplugged at 6am and at 4pm i still have about 75-80% batt left.
This is with about approx. 2 hrs of talk and 30mins of data usage and voice calls paired to my BT headset. My screen brightness is set to 40%

I once got up to 20 hours of moderate usage. But with heavy usage I get about 12 hours or more. I lose about 7% when watching an episode using flash....kinda sucks but I watch a lot of anime online. But I use this as my main phone too. Its replaced my nexus completely. though it was nice with my nexus cuz I could swap batteries. This is how I condition my battery. I let it get to about 2-5% then I recharge it. I don't let it get to zero cuz I heard you can damage the cell. sometimes I charge it to about 20% then I unplug it and drain it to 5% then back up to full. I just kinda switch it up. At first I was getting horrible battery life but ever since I started conditioning it this way I get great results.

Is any one else getting terrible battery life with jk6

I get 4 hours tops.
I was getting almost 18 on j2.

Did you installed another kernel?
I get great battery life...

I installed the stock jk6 that som posted.

Lol we need more than that to help.... what post?
I get anywhere from 10-16 hours on Macnut 13 with JK6, depending on usage

4 hours with what?
Sent from my SGH-T959 using XDA App

I get great battery life with jk6. 5 hours idle and didn't drop even one percent, but it drains fast if I use wifi.

What if you delete MediaHub and DRMua?
I seem to get much better battery without those.
I also enable WIFI during sleep... it's in the advanced settings under wifi.
And of course I remove all of the other bloat apps.

JK6 with all the crap removed and I average 18-24 hours with moderate use. The lowest I've seen is 12 hours and I had the screen on for almost 7 of those.
Looking forward to when we get source code and can run an undervolted kernel.

I get really great battery with JK6. I suggest you to do battery conditioning.

JK6 has great idle battery life for me but as soon as i start to use the phone for low activities it drain faster. By "low activities" i mean as in making call, use map, navigation, changing settings.....
Here is my usage report:
3h since unplugged from over night charge
73% left
Display on for 45m 19s (lowest setting w/ auto brightness turn off)
Voice call 45m 21s
Cell standby 3h
Phone idle 2h 15m
To me this was worst than when i was running JI6. Also i lost 3G every now and then in the same area that i travel everyday.

Using maps and navigation are some of the most power-consuming tasks you can do with this phone. Navigation in particular killed my Vibrant dead in a few hours.

The kswap process eats a upon of battery when in use on the jk2 roms. I thought jk6 had this fixed, but it may just be better on the custom roms. I get great battery life on my jk6 rom.

I had similar battery life using various custom kernels. Installed Aux. 2.1 with stock. With heavy use I am running around 8 hours. Normal use around 12-16. Those other kernels will eat your battery alive. Try a stock kernel. Conditioning doesn't do crap.

noticed this also, doesn't really make a difference to me.

Most of these problems are user error. I woke up today with around 70% this mourning at 7am. Its 12 hrs later and im at 42%.
My Day:
combined 45min of calls
atleast 30 txt message
Ton of emails and they sync all day
Started my music player at 9 and didnt pause until 5pm. playing out of speaker
Browse the internet off and on all day
downloaded a 100mb mixtape torrent through 3g
screen brightness at about 60%
Probably a couple other things but app called Battery Left is telling me I have 10hrs left.
I really suggest running all stock. I need no lagfix/special kernal or anything with the newest leaked samsung firmware. Havent had a single issue since I switched to this rom.

I'm sorry, but I have a very hard time believing that, ALL THAT, only took 28% battery.

17%after a couple more torrents. Not wirth trying to prove but the stock rom made my extended battery worthless besides special occasions.

Thanks for the help. My battery died after four hours as expected. Plugged in and reconditioned and let it charge till it was full. Now It's been about five hours unplugged and I'm down to ninety six percent.
However as some of you have posted my battery drains VERY fast once I use it sparsely. It dropped almost 5 percent after a few mins of browsing the market. Weird. But whatever standby is amazing.

Battery, it's now time to exchange you!

I'm so giddy right now. I've ordered an OEM battery for my Vibrant, and i should be getting it any day now. The reason for me ordering a new battery is limited usage time. Lately when flashing any ROM, I make sure It is at 100% charged. I will normally get about 4.5 or less hours of usage - using a little app named 'Battery Left'.
I don't use a task killer. Ever. I know this has some controversy signed to this, but the Android OS is engineered without issue regarding this.
I Use WiFi whenever I can (uses a fraction of the power 3G radios use). When I CAN'T use WiFi, I make sure it's turned off so it's not wasting power scanning for hotspots.
I make sure GPS is off whenever i'm not using it.
I set display timeout to 30 seconds, set brightness to Auto, or manual and the lowest. Little trick, if Brightness is on manual, you can adjust it on the fly by swiping left or right across the task bar.
I let the battery TOTALLY discharge at least once (twice is better) and then charge to full. This doesn't condition the battery, this just calibrates the battery metering software, so that it knows for sure where zero is, making the metering more accurate.
I try to use a darker colored wallpaper, blacks and reds and deep greens and blues use less power than lighter tones, and white is the worst.
I get a half-day out of my rooted Vibrant on T-Mobile, and I actually use it as a phone (amazing huh?), PDA, game machine, ebook reader, etc, it's not just in my pocket on standby. Battery life has nothing to do with it being unlocked/rooted.
I understand the biggest reason why people think THEIR particular smartphone has some sort of battery problem: They just got it, and are using the hell out of it. We tend to not set it down in the first few days/weeks, we're always fiddling with it, showing it to our friends and co-workers, etc. Once the new and shiny wears off, and we settle into more "normal" usage patterns, we start noticing that we get a lot more battery life out of the device. Some people think that the battery is now "broken in", but the truth is, the USER is broken in.
Some of my POWER hungry apps I use on a daily basis is 'SportsTracker' which I use riding my bicycle to and from work (7.3 miles one way). SportsTrack uses my GPS and tracks my ride in REAL time. It sends a link to Facebook and Twitter, where my friends, and family can watch me go. This app uses about 17% of my battery - one way. So, at the end of the day, just using SportsTracker it uses at least 35% of my battery.
Speaking to the heavy users, how many hours do you normally get using your Vibrant?

With 20-30 calls a day, 20-50 texts, dozen or so emails and listening to music and just geeking on the phone Axura 30 hrs before it is 15% Trigger 24 hrs before 15%, but then, that's how it works for me. Since I got rid of stock roms, I have had ZERO battery problems, I only use Task manager. Deleted all the bloat and I have screen set to 50%. Battery is no longer an issue

With Bionyx 1.3 I let the phone sit idle (exchange email running in the background though) from 8AM and till 4PM it took only 15%
Skype+music+movie for around 1 hours and it's down 15% more (now 70%)
I guess it'll last 1.5 day normal use and 2 days idle use

That's a great battery life. My bionix eats more battery on almost the same usage. I have around 76 user apps installed and some bloater. One thing I have noticed using system panel is when I sleep, my phone sleeps with me and uses an average of 1% battery per hour. Is that good? I still I think im not getting optimal battery life when im actually using the phone.
Sent from my Samsung Vibrant (Bionix-V 1.2.1) using XDA Premium app

You guys think that's good battery life? Nah, this is good battery life.

I always got 20-30hours a charge with most of the Bionix roms. However with Bionox 1.3 I struggle to get more than 12 hours with the same usage. I did notice that new app BLN (using your soft keys as notifications) was reported on some other roms as a battery drainer, so I have uninstalled via Titanium. I will report back tomorrow if that is the issue. I still use KA5 modem, so that part has always been a constant

Weird. I'm on 1.3 as well. I'm 15 hours into my charge with normal usage on 3G/WiFi and I've got 25% left.
Sent from my SGH-T959 using Tapatalk

I'm 15hrs in running Bionix-v 1.2 and i have 42% left. That's with GPS on all day....phone in pocket from unplugging to about 3:30pm. Then only light use.
Days that I use heavily I'll have to plug in around 4pm. I'm not too happy with my battery life. I love my phone...but my old iPhone 3G had top notch battery life! lasting 3 days without charging.
Is it not weird how these times fluctuate so much between users?
Will the new Galaxy S 4G battery fit in our phones? Or will it even be worth it?

Do you have the superpower app? It saves my battery big time when phone is sleeping.

I ordered a batter charger, two spare regular batteries and one spare extended battery last month for my vibrant.
Now I keep a spare charged battery in my pocket and I no longer have to plug my phone in anywhere I go. I just swap batteries and put the dead one on the charger when I get back home.
If I am going to be away from home for more than 24 hours then I put in the extended battery which gives me about 2 days worth of use.
Its a bit of a pain to have to be down for a minute when the battery is dying, but I am more content using the phone this way since I can now keep it with me instead of leaving it upstairs or on my office desk to charge.

My phone is on the stock KA6 kies and from 8-8:30 it is off the charger on 3G. When I get to work it is on WIFI with WIFI Calling(no signal indoors) from 8:30-12:00 and goes back on 3G. then at 12:30 it goes back on WIFI(calling) and sits like that till 5:00. Usage during that time, some email viewing, 10 txt or so, 5 min phone calls and that is it!! from full charge at 8am to 5 pm I'll be at 45-50% battery left and what you read above is all I do with it all day. Battery life is horrible. Not much I can do(unless someone has an idea to fix the issue) as I need WIFI calling otherwise why have a cell phone?

Food for thought

So 16 hours with 3G and WiFi Calling on all the time...on the STOCK Samsung crap? Thats pretty awesome man. WiFi calling is a HUGE drain. Spend the $2 on an app called SystemPanel. It will tell you exactly what is taking up CPU Cycles which, of course, uses battery.
I go 24 hours on a charge with routine use. Granted, everyone's use is different. But I got two days with the KA7 modem on Bionix V. I see no difference with 1.3 (haven't used it enough to tell). Granted, I had WiFi Calling frozen and was on EDGE most of the time and turned on WiFi when I needed it. I've observed WiFi Calling using excessive CPU cycles when it isn't even on. Its pretty poorly coded. I recommend freezing wifi calling when you aren't using it.

SyndicateROM Frozen (EB13) - Battery Life Thread

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.

Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.

I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.

I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours

With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.

1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,

I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.

Over 24 hours on a single charge!! Awsome battery life!

I just wanted to share my battery life results of my NS with the community. I was able to get over 24 hours of battery life on a single charge. What amazes me more than that, is the fact that my battery was only at 72% when I took it off the charger. Much to my surprise the battery lasted me for the next 24 hours before it dropped to 16% and I decided I needed to charge it before going out this evening.
My configuration:
Rom: NS Collab 1.0.17
Kernel: Netarchy 1.3.0.2-CFS
Screen Brightness: Auto
GPS: On
Wifi Sleep Policy: Never Sleep
Email: Sync every hour
Facebook: Sync every 4 hours
Clock Speed: No special governors enabled
Most of the time I was connected to a WIFI network
Hope this may help those that have been having problems getting optimum battery life on their NS.

not bad i guess, i've gotten over 48 hours

Yup, awesome battery life with CM7 as well.

Care to share how?

limited phone calls equals great battery life.

Yeah SI_NZ pics don't show any usage of the phone. Mine I talked for about 2.5 hours and was using facebook a decent amount. I also did web browsing, some videos for a little while, and I did a couple of video recordings of my son. Overall I used my phone a pretty decent amount during this time period, hence why I was so impressed. The same type of use on my EVO would have resulted in me having to put the phone on a charger before halfway through the day.

Darn... I'm stuck between the Nexus S and the HTC Desire HD, but the battery life on this phone must rock.
But how is battery life on a STOCK OS? I'm not much to root.

That seems to be a battery killer

I've found a few battery killers, maybe we should make a list and make it sticky. My phone easily lasts like 36 hours with normal use, which include a little gaming and lots of surfing, texting and calling. The apps i have found to drain the battery so far is:
Latitude activated in google maps. This is insane, latitude makes my phone go dead in like 8 hours !!!
a media player that i can't remember the name on :/

The Desire HD kinda sucks for battery life and I found it was too big/bulky feeling. It wasn't as fast as the Nexus S in everyday use either...the Nexus S is quite quick.

I'm on stock 2.3.3 out of the box and battery life is very good, better than I expected. I don't have too many specifics yet since I've only had it a few days. But so far it's impressed me again today with over 13h 30m 43s, with 44% display use, and 72% battery left. Perhaps I'll comment on the weekend after I calm down a bit and use it over a more typical day. But as it stands so far, I expect to get 1 day heavy usage, 2 days on daily typical usage, and 3-4 days when using the phone very little (like while camping/hiking).

Well 8 hours is quite good since it runs the GPS constantly and updates your location on the Latitude site. I ran other GPS apps on my Desire and typical times were ~4 hours before the first battery low warning. I haven't had a chance to really test the GPS properly, but initial use looks good.

2 days is pretty good. but you barely ever had the screen on. I can normally get 20 hours which lasts me the whole day, so I'm fine with charging every night.

Wow that's fantastic. I'm sold

I'm on stock 2.3.3 too. Typically I get about 35-40hrs.
WiFi: Off.
BT: Off.
GPS: Off.
Email/Calendar Sync: 1 hour.
Facebook: Off.
No fancy widgets though, just the stock clock and stock calendar. No task killers either.
If I game for about 2hrs during my daily commute, the battery lasts just long enough from 6am to about 11pm.

Forgot to mention how the phone is setup:
WiFi is off most of the time (I have 6gig data plan)
BT is off as I don't use an earpiece
GPS is always enabled (I'm a geocacher)
Gmail is set to manual sync (work is too busy for personal email)
Facebook/twitter/whatever are all disabled/not installed
News widget is set to update every 12 hours
I use a Live Wallpaper, Beautiful Widgets with animations, and I'ver never used a task killer as they're not needed.

Don't know where I have read that, or if it's just an impression. But I think that wifi connection consumes less battery juice than 3G connection. And push-Gmail doesn't increment battery usage.

I came from a blackberry (actually I still use the blackberry) and I was initially annoyed by the quick battery drain. But after seeing my friends with iPhones needing to bring chargers with them everywhere just to use whatsapp and gchat constantly, I was really glad I got the nexus s. I recently went on a road trip where I used the gps constantly to drive 4 hours out to the destination, used the phone there to whatsapp and call my friends, used the internet to look up restaurants, and then used the GPS to drive 2 hours back to our hotel and it lasted me the whole day. I'm stock everything with 2.3.3. I love this phone.

I managed to get over 48 hours on a single charge.
Thats with around 7-10 short phone calls per day.
Some whatsapp/sms
a few minutes of angry birds here and there
and some web browsing over wifi.
My WiFi is always on and set to never sleep.
sync is off.
GPS off
BT off.
My data is also usually off, since my work data plan is rather small.
Also i have simi clock running that updates the weather every 3 hours when WiFi is connected (which is most of the time).
I am on stock 2.3.3, unrooted.
after 3 days I had around 25% before I connected it to the charger.

The battery on nexus s is great, much more better than my old SE X10.

Could you please all tell whether you are on 9020 or 9023? I heard average battery results were not so positive with 9023 sclcd. Here I can only acquire 9023, and I have been reluctant to buy so far as people don't seem to reach quite the same autonomy as the samoled nexus owners.... Thanks!
