So the day I bought my vibrant I had data issues. I talked a tmobile tech support guy and he helped me with my problem, great. But afterwards he asked me how I was liking my phone since he had one as well. We talked some about the phone and all, but then I asked about the battery life.
Heres the interesting part, he said after getting around 5 hours of use out of a full charge, he put the battery in the freezer over night (in a zip lock) and charge it afterwards. He claims to be getting a whole 24 his of battery with moderate use.
Is there any truth to this statement? I'm sure he was over exaggerating to some extant but he was a tech and I wanna take his word for it but dont want to try it lol.
Another thing is I want to know other ways to improve my battery life. I heard "training a battery" thrown around these forums, how do I do this?
I try to keep stupid services from running by going to settings>app>running services. Is this enough or is there a better way?
First post, hope it was a good one lol.
I hear ya man the battery is really bothering me too. It's basically dead by the time u get home, which is not good enough for me. I called T-Mobile and they are sending me another battery.
When I get the new battery I'll try the freezer thing.
Well, gotta go... battery is almost dead at this point. : (

when i got the phone i calibrated the battery like i did with my g1 with the cm releases. basically let the battery die completely then charge fully. don't know if that had any effect, but with how much i use my phone (moderate-light texting, browsing, gps when it works, no gaming) i could probably get through 2 full days. with playing some games i can still easily get a full day.
putting the battery in the freezer overnight shouldn't have any long term effect on the battery. it may improve your battery life very shortly because a colder battery holds it's charge better, but once it's heated up (or at regular idle temp in your phone) any small benefit you may have had is gone.
Try Juice Defender. It is working wonders for me. I am going on 8 hours of up time and I am at 75%. Normally I would be getting close to needing a charge.

What settings do you use? Do you use the default settings from the setup?
What the heck are you guys doing to kill your batteries?
I use my phone off/on all day off the charger at 6am and I turn it off and charge it at 11pm. Often I'm normally around 30-60% depending on the use through out the day.
Turn off what you don't need. I mean do you need wifi on all day? Do you need 3G on all day? I'm guessing you don't unless you are streaming video all day.

Yeah I don't get it, this phone has great battery life for me. I get about 20 hours out of a charge and I use it quite a bit.

Can you elaborate on your settings? I was thinking of installing this app and getting rid of the task killer since I'm getting very inconsistent battery usage each time after a full charge. Have you tried Ultimate Juice?

I think its just luck of the draw. When i first got my Vibrant i was getting at least 20 hours out of a charge. I had to exchange my phone due to a few annoying dead pixels and now im lucky to get 8 - 10 hours out of a charge. Everything is set up as it was on my original phone.
I just use the default settings at startup.

I have all widgets turned off, wifi off, gps off, brightness on minimum and a solid/static black wallpaper.
I use the phone for very few calls and very few txts... mostly use it for web browsing throught the day and some news apps - with a little paper toss mixed in.
I use my phone more than the average guy, but the usage is in line with my usage on my iphone and HD2. I know how to be gentle on the battery, but I still have to charge it when I get home from work.
My battery lasted 2 days the other day. Got down to 15 percent. It's very strange. I was using it but not very often maybe once every few hours. But I played some ff7 to demo to my friends, used the gps to get directions. Most importantly I started killing all nonessential apps with astro immediately after I stopped using them. I think this is what's prolonging my battery. Sure theyre not using anymore cpu cycles but they're still taking up ram, and that is a constant drain folks.

There is no difference in draw whether you are using 1K or 256 MB, the chip will always draw the same amount of power to maintain the memory.
I measured current consumption from the battery. It takes about 20 to 60 seconds for the CPU and everything to ramp down into their sleep state. Anything that wakes it up often kills batteries quick. I believe most of the power being used is idly switching sleep states. Can't wait for custom ROMs to allow tuning.
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...

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

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?

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.
What rom (stock sense look) has the best battery overall. I rooted my moms evo to get her a great battery life but it still seems to be dying really quickly. I am using 4.3.1 kernel. She's only getting around 6-10 hours of battery before she has to charge it. I had the evo before and could get a full day and a half before charging it. I can't remember my setup since I switched to the evo shift. Any suggestions would be greatly appreciated, thanks.
im using the cm7 rc 2 whatever kernal is package there is PHENOMINAL im at 60% @ about 12hr..... Moderate use between wifi and 3g

That's the best you're gonna get with NORMAL usage and a REGULAR battery. All those users that say they get like a day or two are full of it. They get that long because their phones are sleeping most the time. I've used EVERY rom/kernel combo out there and the best I ever got was about 15 hours. I literally use my phone all day while at work from browsing, texting, calls, facebook ,twitter, and games. There should be a definition for moderate. I consider myself a heavy user; unplug at 7am and my phone last until about 6pm with about 20% left. Its not going get any better than that for a moderate to heavy user. From sense to aosp with the stock battery I just never achieved better results but I'm pretty happy since I get to work at 8am and get off at 5, buy 7pm its nearly dead and I just plug it up. You should invest in an extended battery imo.

I agree to a point. I mean, it all depends on usage. I can believe someone with light-moderate use can easily get a full day with the right setup. I do it now with CM/Savage, but I'm definitely not a heavy user.
I do see some people make wild claims of 2-4 days without a charge.. and I think it's possible IF you don't use your phone or you turn everything that makes it a smartphone off. Which is pointless IMO.
Nobody can really give you the perfect setup because every EVO seems to behave differently. We can only make suggestions. Make sure your mom s awareof all the things that can drain battery (push notification, updating widgets, weather updates etc etc). I would then research a good sense rom/kernel because CM7 is a definite WIP with different issues for different users, it may turn her off.
Maybe check out MikFroyo or Myns rom. I hear a lot about how good they are.

+1, its just crazy I see people throwing crazy hours out there lol. I think if your phone is sleeping 75% if the time then you shouldn't even talk about your results since that doesn't fit into the norm for usage. Most people check their phone like every 10 mins(don't quote me) I know I do lol. People throw around like 36 hours and even longer its insane to me.

I don't know about not being able to get more than a day of battery life and use your phone. Using MIUI with a Savaged-Zen kernel I was able to go almost 2 days without even plugging it in once (I'm specifying this, because I've seen screenshots where people claim crazy battery life, but the graph clearly shows that the phone was plugged in and charging several times throughout that time period), and my display usage was still 44% of my battery. That was still minimal usage for me. I posted the screenshot in the MIUI thread if you care enough to check.
I do mostly agree, though. Most people posting outrageous battery life have display percentages around 5-10%, clearly never removing the phone from their pockets.
Anyway, as for the OP, the biggest missing variable is that we don't know at what percent your mom considers it necessary to charge her phone. If she plugs it in around 50% to be sure she can make it through the day, that means she could have gotten another 5-8 hours of battery life (assuming she's not draining it down to 0%). This fact could make the difference between bad battery life and a paranoid mother.
Try the ava froyo z3 I love it best rom I've used so far so guess I'm sticking with it o and get her juice defender with ultimate juice and lock it down so it kills anything she's not using

I agree with most of you people. Initially went to FreshEvo by Flipz when I rooted and battery life did not change much from when I was running stock. I have since switched to CM7 and battery life is significantly improved. Now getting 12 hours on a single charge with moderate use. I always turn 4G and wifi antenna off when not performing any data-intensive use. But I refuse to kill my 3G data connection when my phone is in my bag or desk while at work. Reality is that it IS a smart phone and killing the data to save battery life defeats the smart phone bit, no email no Facebook syncing no MMS etc. The only time I kill 3G is when I am in the mountains skiing.
My problem is that I work a 12 hour shift so 12 hours of bat life is not ideal. I have invested in an extra charger but would obviously be happy to not use this. I have heard lots of testimony that the savaged Zen kernals show some promise in improving bat life. When CM7 final drops I plan on flashing one of these kernals with the new ROM on wipe. I will stay away from the SBC version though for fear of improving battery charging but having my phone melt down or pop on the night stand next to me while I sleep... or worse in my pocket!
I will report back if I get any significant results.

Yours suffers from the same issue as everybody else. Only the more you use the phone the less you notice it.
Not exactly sure if it's that simple but you used 70%. 17% of this is used by a process which shouldn't even be in the list, android-os. Thus 12% of your total battery has been drained for no reason. Meaning your battery should have been at 42% at the end of the day.
Not saying 30% left is bad, it is probably better than most other phones,but it should be 42% left in your situation.

Doing a simple math should tell you that Android OS has used 12% of 70%... thus, means 17% from total battery... so he should be at 47% instead of 30%.

That requires RAM and a bit of current to keep the data intact.

Everybody out there with that heavy battery-drains.. did you guys root your phone? if so... thats why you have a heavy battery drain. Read that somewhere, unrooted mine, and have a very nice battery-lifetime since then..

I´m following now for 3 weeks the batt threads and I am closely watching my batt drain but honestly I can´t find any flaw.............
While my wife with her HTC desire plays 2 x a day for 1h car drive angry birds and the desire is dry then she tried the same with my SGS II and drains only 30 %
In the morning I read via an Austrian newsreader the news of 2 newspapers for approx. 45 minutes, check mails etc. and it takes 4-5 % in this time.
During day I check mails, download newest apps from market, update existing ones, do some calls, check mails, update my calender etc.
Let´s say - compared to my HTC HD2 (with extended batt) - I use it more heavy since it became somehow part of my body ...............
Still in the evening I am on 40-45 % left and then starts heavy use (XDA, other forums, blinx funny videos, Youtube, trying new apps etc.) and plug it in around midnight with 10-15 % left ..........................
I am quite happy with this.
I have installed Startup Auditor and disabled AP News and most social hub apps, music hub, maps and some apps that load at startup.
I have Juice defender Pro trained now well to my needs
I use Android Booster to clean up and shut down apps automatically without restricting functionality of email, facebook and so on.
Android Booster also shows me EXACTLY which apps use how much of my batt and after one week of verx close surveillance I cannot find any process that eats up my juice in the background.
I fear a lot of You mistake the power-percentage of Android OS as an absolute value.
If total drain is 10% per - let´s say 5 hours - and Android OS is eating 50% it is the equivalent of 5% total juice for Android OS in 5 hours = 1 % per hour (these are approx. my values) and somehow this dream-machine has to work to get it going and doing what we want it to do .....................
Now I leave my HTC HD 2 as a backup completely unused (just updating emails every hour and calendar sync every 4 hours, weather forecast with radar charts every 6 hours) and this then consumes 20 % of my extended (!!!!!! 2.600 mAh) HTC HD2 batt.

Hibernating (S4) does not require any power (the RAM is written on disk), only when in sleep mode (S3).
You must be new or something. Rooting wouldn't cause battery drain. Its what you do after rooting. Freezing things you don't use helps out a lot. Touchwiz always runs in background.

How long was the screen on... I'm guessing 1 hour 40 minutes.
My galaxy s2 is drinking batrery juice like fish....my battery discharges at a rate if 3% per 10 minutes of wifi and light tinkering. Which is why i bought 3 soare batteries from ebay.

Agreed... all this battery discussion is getting somewhat tiring. People buy these handheld computers to conduct these battery tests to see if their phones will drain less than 10% if idling for over 24 hours... seriously? Why not just get a nice shiny paperweight?
My phone is getting hammered all day long as I use it as my computer away from the office, and I am away quite often. 2 pull E-mails + 2 push E-mails, tons of text messages with customers/my manufacturing sites, running around my region using GPS/Google Nav, conference calls throughout the day (much of which is over bluetooth), checking realtime inventory via the web, etc. I'm lucky if I have 25% left on my phone at the end of a long day.
BUT, that's the point: All my colleagues that use their Apple devices just as heavily are constantly charging their phones throughout the day. I don't bother to charge during the day and have yet to have it run out on me. After doing all the things anyone should do (ie, freezing unwanted apps, making sure there are no rogue apps running, etc), I am getting far better battery life on my SGSII than I ever did on my SGSI running custom ROMS + Speedmod battery saving kernels.
If you are getting odd drain from idling when you're doing next to nothing, there's a good chance you have something going on in the background just sapping your battery.
Does anyone know if there's a way to disable Android from automatically dimming the brightness of the display once the battery gets 'low' (<15%)? I find this 'feature'
annoying. Tried disabling 'power saving mode' and also 'auto adjust screen power', brightness is on manual as well.
I rooted today and installed titanium to freeze some apps but I cant figure out which apps I can freeze without f-ing up the phone. Can anyone tell me which apps to freeze,or forward me to a topic with this information?

If you just bought it yesterday..... then give some time to calibrate thr battery! Just keep using it and let the battery reach normal. Most new batteries require 3-4 charges to start running fine. Give it a few days

+ 1 the battery needs a few cycles to break in. Also, are you rooted are you running a custom room or kernel these things can have an affect on your battery also.
No I'm not rooted or have a custom kernel. I'm running stock.

Strange, I get a day and a half of heavy use with the brightness maxed and running a live wall paper. I thought my Xperia Arc had great battery life but the Nexus S is insane!
OP are you using task killers? Don't. It takes up more battery for your Nexus S to re-start those apps than it does to manage them on its own.
It took my battery like a week to act right. Give it time

a day and a half?? howd you pull that off? im usually charging about 10-14 hours thorough heavy use.
agree with everyone else, give it a few days.
I used some advice i found the said kill battery, charge full, kill battery, charge full, kill, charge, then use it. Charge it while it is off during that time.
First couple of charges, the battery would die after about 5-6 hours of constant "messing around" with the phone. Now it seems like it'll last a good time.
Im completely stock as well.

I dont know. I don't really game on it so maybe thats it, but I am surfing the web constantly. When I go out I turn wifi off...thats about it. Oh and the only widget I am running is a clock and the weather for the clock is set to refresh every 3 hours "simi clock" is what its called.
Thats about it, I dont know what else to say. I came from an Xperia x10, Samsung Captivate, Xperia Arc, and now the Nexus S and its MILES better...so much so that I have decided that I will only ever own a "Nexus" line of Android.

Like everyone else said you really need to give it some time to break in.
My first day with the Nexus the battery was dying as I left work (roughly 9 hours off the charger).
After owning the phone for about a month now it's changed dramatically.
It lasts well through the entire day, every day. Before I go to bed it's usually sitting around...
70-80% LIGHT use.
50% Moderate use
35-40% Heavy use. (Note: I don't play games, Heavy use to me is multiple short calls, many emails, many texts, IM)
I've never actually had the phone die on me.
I'm using CM7 (Latest Nightly) and the Netarchy CFS Kernel (default settings with the exception of VooDoo Color tweaks)
I don't use Juice Defender. Phone sits on 3G most of the day at the office, at home it sits on WiFi with the WiFi sleep policy set to never. (Wifi uses much less power then 3G, if you have WiFi, USE IT! and set sleep policy to never so WiFi stays on constantly instead of switching back to 3G when the phone is idle)
Do use a task manager but it didn't seem to make a huge difference.
Aside from letting your battery calibrate, you should try out juice defender. I know alot of people might scoff at a such an application but I've experienced over a two fold increase in battery life using said application. However I am running an undervolted netarchy 1.3.4 kernel with Oxygen, but said increase in battery life is with the same configuration.
Yeah it takes around a week to break in the battery. My battery life is pretty awesome. I usually charge it every other day now. It lasts a long time.

Guys... battery break in isn't gonna change his usage from 4 hrs to 12 hrs. No battery break-in does that.
In all these cases I suggest looking at battery info in the OS itself to see if something kept the phone awake or whatever.
Sure heavy use in your first few days will always take a huge toll on battery. Calibration shouldn't totally throw off your battery life down to 4 hours either.
You guys who say heavy use, can you quantify that?
talk time per day?
texts per day?
roaming?
4g?
how many emails sent/received per day?
time on internet?
/shameless plug
try battery tweak in dev forums... i posted it in both of them

I'm in the same boat as you. Just got my Nexus S 4G on three days ago and the battery dies QUICKLY. The first day it died in 5 hours (with normal use and 4G off). By the time I unplug it and get to work, which is only a 20 minute drive, it's already down to 93%. I'm hoping everyone else is right in saying that the battery just has to be worked in a little.
I have 8 hours on battery right now with about 40% remaining in day 2 of my Nexus' usage. I made about 6 phone calls, sent out about 20 text messages, browsed the internet while waiting for a job interview and played Plants V Zombies when I was taking a dump.
I really only expect it to improve from here.
Out of curiousity, does anyone here have their "Use Wireless Networks" checked under the "Location and Security" settings (where it uses your 3G)? I have this enabled and I know this will drain my battery, but I wonder how much? The only app I have that updates my location while the screen is off is the stock News and Weather app (which only updates every 6 hours, a bug that automatically turns itself back on if you reset your phone). How much collection would Google do other than that?
Also, the other thing I have enabled is my Exchange set to push through the default Email app. However, this never really shows up on the battery usage app, so is push STILL killing the battery a lot through the stock app?
I'm just trying to see how people can get two days with 50% left after work (if just on 3G). On WIFI, MAYBE, but def not on 3G......
