So here's a screen grab of my phone's battery. I work 9-5. Started the day with fully charged battery, and end of work day it's almost dead. Honestly, I never thought it would be this bad. I don't play games or watch endless videos on youtube. I've sent about 15 texts messages max, used the phone to make about 4 calls for a max talk time of 6min. And browsed the net for no longer than 5min. I have wifi always off, GPS off, my screen is always set right down to absolute minimum all the time. I have never used live wallpaper, and have a black wallpaper. All I've done to this phone is root it and remove a lot of bloatware. Nothing else. I've read through the forum and came upon this thread:
http://forum.xda-developers.com/showthread.php?t=1092249
So without running the Bali kernel or running any specific rom, Is this the expected battery life for the average person who just leaves the phone completely stock.
*UPDATE*
JuiceDefender works!!! Battery now last much longer. Thanks goes to jager555 for the great suggestion.
Most high end ones are. because android runs things in the background and allows you to customize many settings, Battery life usually looks like that when you first get your phone. That said once you get familiar with your phone you will start to recognize things that run in the background that serve you no purpose and you can stop them or get rid of that app. You can also get custom roms that have great modifications to enhance your battery's life. It takes some experimentation but gone are the days of getting 4 days out of you Razr. Try searching "battery saver" in the market, too.
It could look like this...
Well I have to say that's quite shocking. The average person just has no clue on how to flash roms or anything like it. They just charge their phone and go. It really makes me wonder why Google or the phone manufacturers wouldn't think battery life to be a priority. The battery life isn't just bad, its unacceptably bad.
Thanks for the input though.
Yeah no thats not normal. When i first got this phone i could go up to twelve hours non stop with regular use text here and make some phone calls, watch one or two videos... And i still had battery left probably like 40% maybe less. Well at least for me i dont know if i was a special case or not.

if you are on stock and do not use the bali kernel, get Juice Defender from the market. try it out for 2 days and get back to me on how it works. if you want the best battery life, especially since you take off gps and wifi, set it to aggressive. that should make the battery last MUCH longer with your type of usage. but once again, use it for 2-3 days for it to settle in properly

yea, my dad is on stock with this phone and it wouldnt last from 7am to 2pm. now it lasts from 7am to at least 8pm with the same type of usage. its a neat program. i hope it works well for you.
I'll second juice defender. Even the free beta version has helped my phone last a long time. but if you aren't using your phone much, you should really get a lot better battery life than that. if it's brand new, it can take the battery a couple of charges from a full drain to get up to snuff.
With light use, I can get well over 2 days, and have even gotten over 3. Here's a screenshot I took a couple of weeks ago.
mike-y was the one who introduced me to juice defender, btw. great find, man
Wow, Tempott, that's very short battery life. I actually had pretty decent battery life on stock. I lasted about 12 hours on moderate use. Then again, it's funny that I last 18 hours on very heavy use now with ICBINB with 4G on, first level brightness, and sync always on (no JuiceDefender, etc.).
i am using Audiophile ROM. i get 10-15h of battery life.
Im using black ice with bali 3.1uv dsexton's build.prop and im getting round 12-15 with heavy use(mobile AP, pandora, calls)

Sorry for the late reply, but I just wanted to give the app a thorough usage. I'm happy to say it really makes a difference. I was so disappointed with the battery life that I had a serious bout of buyer's remorse. This App made a world of difference. Thanks for the suggestion! Glad to have this phone now. Check out the screen shot!
Nice!! that's great. I liked the beta app so much I went ahead and paid for the "plus" version. "Plus" gives JD control over wifi, and lets you set a "night mode" that turns off data/wifi/gps/bluetooth during the night when you sleep. There is also app control, which I played with, but ended up just disabling it (makes things a lot simpler).
Honestly, if the beta is working for you, there isn't much need for the paid versions. especially if you put your phone in airplane mode when you got to sleep (or just turn it off).
btw, current uptime = 40 hours, 45 mins, and I still have 70% battery left.
It seems to me Battery Calibration doesn't work...however, this phone lasts longer than the Sensation, which personally sucks.
battery calibration works fine. make sure your phone is charged to 100%. check spare parts amd make sure it is at 4200mV. sometimes, if it is not calibrated properly, it will show 100% and not 4200. unplug the phone and immediately plug it back in and you will notice a fluctuation in the numbers. usually, it is a big fluctuation. once you are as close to 4200 as you think you are going to get while the phone is plugged in, open the battery calibration app and click calibrate. then immediately unplug the phone. use it until it is completely dead (i do it until i shuts down). once this is done, charge the phone until it is 100%. do no unplug the phone until it is at 100%. then drain it again. and charge it to 100% again. after that, use it normally for 2 to 3 days and you will notice the difference in efficiency.

I would like to add that the first charge drains amazingly fast. You can be idling your phone the whole day, and it'll still be gone.
After you go through a few charges, it'll be omgwtfbbqhax battery life.
Btw, I'm betting Bali 3.3UV + JD is pretty beast battery life compared to Bali 3.3 + JD, right?
Juice defender works great for me as well! Very noticeable difference

This is my moderate use. Few web here and there facebook, some calls/texts and instant messaging for a good 3hrs
I am running cog 2.2b5
Just wanted to compare battery life and post the rom you are running too
Sent from my SAMSUNG-SGH-I897 using XDA App
my battery life sucks. i get about 10% per hour....
What Rom are you using?
yeah my batt isn't too great either. 2 days on Cog V5 now. Each day has been roughly 10hrs with about 4.2hrs use. Each day I ended with maybe 1-2% left.
Is this normal? Froyo didn't help a bit. In fact it may have made it slightly worse.
When I flashed b5 ... it was great. Then I found my gps sucks on it so I flashed again and I found that the battery drains like water 1% every 5 mins! ( Idk what's going there) Then, I flashed again and the above post is my result and my gps still sucks. So maybe if you flash it again it might help. I re partitioned in odin as well.
I am using Froyo (JI6) with lagfix and I get a consistatnt 12+ hours of moderate use. I usually charge my phone every three days.
Cog 2.1.7
I have to charge my phone every night. I have used multiple roms from cog 2.1 and even cog 2.2 as well as stock and it all seems the same.
There is no way that is an accurate picture... there is no way you made phone calls or used the facebook app without it showing up in usage.... u may have gotten 40% out of 12hrs but you did nothing with your phone

I use tons of apps on my phone and the only things the show up in my battery usage are: Display, cell standby, phone idle and voice calls.
you need to recalibrate your batteries or flash from 100% as DesignGears had mentioned earlier.
i now flash from 100% batt life when upgrading to new ROMs. or do a search for battery calibration.
Not sure how to do a screen shot but Im running 2.2 beta 5 and I thought battery life sucked but it was because I was checking it constantly and playing with GPS.
Today, after recalibrating battery stats two nights ago I have dropped 3% in 3 hrs of standby and very, very light use.
Also, to recalibrate battery stats I downloaded terminal emulator and did the following
su
rm /data/system/batterystats.bin
I had drained it fully down to 1-2%, did the above commands, plugged it in and charged to 100%. You must be rooted to do it this way I would think since Im using su for superuser.
Yea, I recalibrate the battery on my 2nd flash. the first flash my battery was draining literally 1% per minute. So I reflashed (I thought something went wrong on my 1st flash) and recalibrated now it's normal again.
gocats7: Yup cog comes rooted
Cognition is awesome. With all the features built in, the att crapware stripped out I dont see myself ever running a stock ROM again. In regards to battery though, I think its at least as good as stock if not better. I havent had 2.2 beta 5 loaded long enough to really tell.
I've never had poor battery life. I did have that "new phone syndrome" when I got it and had to charge it a lot. But now I'm going around a day and a half on a charge with moderate use. I use wifi everywhere I can and try to minimize the time the screen stays on.

Have you found that wifi has been helping your battery life? When I have mine on I lose battery at ~5-10% an hour. With it off I lose 1-2% an hour. I have to switch it off nightly so that I don't have to charge my phone again in the morning.
Just the thread I was looking for...
I just recently bought a captivate that had the battery problems it seems so many are having with random shutdowns etc. I would get maybe 12 hours before getting the recharge notice. And that is with very little use. So, along with the advice from these forums, I had it replaced within my 30 days and immediately noticed a difference in the way the phone felt(if that even makes sense). It seemed like the screws were tighter, it was cleaner and it way out performed my previous captivate. Had me thinking I was given a display model or something.
So, to keep it short....I just plugged in after (for me) a very impressive 64 hour strech with moderate useage, some gaming and movie watching. Could not be happier with this phone right now. I cannot for the life of me figure out how such an impressive spec'd phone can use so very little power while locked. It makes me feel like a proud parent...lol.
I <3 My Captivate...

I have actually found my battery lasts longer with wifi on. I only turn it off when I leave the house. For me the wifi seems to be a lot more power/data efficient then my data connection. I can use the phone all day on wifi and still have 20% left at the end of the day whereas when I've been out all day long using data I can barely make it home without it *****ing at me to charge the phone.

I have had the best battery life yet with Cog 2.2 Beta 5.5 and migrating my Exchange server to Google Apps Premium so I do not need to use stock corporate email app anymore. I am pretty happy with this so far although I have only used the new beta for a day so far.
As a bonus, I am even using Live Wallpaper.
27hr, just dropped below 30%. Love it
Am I the only one?
I upgraded to a native android device from a modded HTC HD2 to hopefully have a longer battery experience.
This battery is absolutely trash. My 2 year old HTC HD2 running Sense Android Non-Native ran at almost exactly the same.
I tested my HTC HD2 side by side with a close friend who has an Evo 4g.. Both Devices still being HORRIBLE in battery life performed almost IDENTICAL.
HTC HD2 is TWO YEARS old, why is it so close in performance to our device..
I love the phone in general, it's snappy (once i removed all bloatware).. Boots fast, runs nice.. i have very few complaints about it.
But how does an 1100 MaH battery run the SAME as an 1600 MaH battery?
I thought technology is supposed to improve, but my non native android phone ran almost the same as this one. Took longer to restart/boot up, but general speed is the same, larger screen size.. similar settings, and same battery life. Pisses me off frankly.
That's how I felt. hopefully we will get rom's or gingerbread on this phone soon that will improve battery life. And by gingerbread I mean the leak from Samsung for the i9000. I've been reading reviews and it seems like it Greatly improved battery while speeding up the phone a lot.

I have to disagree. I've owned may android phones including the evo. This phone has the best battery life in my opinion. I can easily make it almost all day with use without charging

Well like I said, i admittedly abuse the phone.. but I'm comparing to other phones getting equal abuse. It stands up about the same, better yes, but not by much.
If I'm barely using it however.. let's say, mainly just texting, yes it will last all day. But that never really happens.
I love how people admit that they "abuse" the phone all day and then complain that the battery life sucks. If you're going to use your phone that much, bring your usb cord. Or strap a battery pack to yourself and plug it in for "all day" use and abuse.
It's the screen. If you want the super amoled you have to put up with the battery.
What i don't understand is that why the Droid x which has similar specs to our phone can go up to 10 hours of continuous web browsing when our phone/vibrant can only go up to 4 according to tests. Is it because of the screen? If it is then that's just stupid.
Sent from my SGH-T959V using XDA App
It was horrible for me at first, but I then realized the system has to calibrate the battery first. I am getting about 16-20 hours with moderate usage now, which is better than the G2 I had before.
My g2 can go up to 28 hours with light texting and 2 hours of web browsing through wifi and 10 minutes of calls (manual syncs and low brightness also). Once I use the gps and browse through hspa, it's a different story. My sister has a SGS4G and her battery seems to drain faster than mine.
Oh, and if I keep my phone charged for a while after reaching the 100% mark, it stays at 100% even after 1 hour of heavy browsing and watching videos. I think we should all just assume that the battery meters are inaccurate.
I use juice defender and put my brightness setting on auto and I can literally go all day with "abusing" my phone.

let the phone die, to the maximus. meaning once it turns off, turn on again until it doesnt turn on anymore. Now fully charge it, once again when fully charged restart the phone and charge it to 100 again. then let it die again, and full charge. should be fine then
i bought a 3500mah extended battery for my phone. the battery is designed to work with vibrant. it really made my life a lot easier.
I noticed if I set the phone to GSM only, battery lasts almost twice as long. If I'm on auto select (WCDMA/GSM), it lasts from 7AM till about 4PM.
But then again, I don't have a very good 3G/4G reception (or 2G connection for that matter), so my phone is probably working extra hard to find signal all day long.
The new Bali Kernel has shown tremendous battery improvement on my phone. I'm really impressed.

Same here.
I used to only have dark wallpapers and take all the other extra steps for my battery to make it through the work day, and as soon as i got home i had to charge it.
I'm now running fireflies live wallpaper, abusing the phone a little more then what i used to, and i still have battery to spare, not by the time i get home, but by the time i go to bed!!
i also have installed bali. seems to do well, as said its all about the brightness.
My problem with this phone is that wifi uses way too much battery. I have it to turn off when phone is asleep but i'll have the phone at 100% with wifi on. Put it on sleep. 4 hours later. battery is at 65%.
If i have wifi turned off. Battery will be at 98%.
Purchased this morning and the battery was drained... Fully charged at 5:30pm. Now at 7:30pm im as 50% with minimal use. a 4-5 hour battery life is not going to cut it.
Hopefully this is just an initial charge issue, but my vibrant never drained this fast.
Worried!
U may actually have a bad batt. But id give it a chance. Drain it down to 0. Turn it back on. Let it die again.
Then charge it while off. If it happens again youll know.

I have done a few charge cycles completely draining it and battery life is still pretty bad...it better get a lot better than this or it is going back.
Also getting random freezes and reboots.
I've got a ton of apps and widgets installed and use Exchange push. Battery life has been just a little worse than my G2. The phone froze after I first configured it and I had to do a hard reset and rebuild it. It runs a lot better after the reset. You might want to start-over and see if it make any difference for your freezes and resets. I'm purely guessing it may be the difference between the phone configuring the SD card and reading off of one that's already configured.
Bad batt. 4 hrs is a wayyyyy bad.

Sounds like my experience too. My battery yesterday lasted me no more than 7 hours. Wooh, I was pissed. So far today though, It's been on for 14 hours and I'm only down to 25% with some medium-to-heavy emailing and texting, and a few 5 minute phone calls. I'm very impressed after this second charge. I'll drain it again tonight in hopes for a little additional life. Stick it out for another day or two, OP.
I'm really concerned because I've had my phone since Monday and have charged it at least twice a day. It's not getting any better :-( I have even froze alot of the bloatware and apps that run in the background. I can't handle 6hr battery life :-(

You mean for an exchange? Or ask for a new battery? Will they do that?
I also have serious battery issues. The battery usage is mostly consumed by cell standby and bluetooth. On my mytouch 4g at most these parameters were a few percent each. On the g2x they are like at 25% usage each. This does not appear to be normal. This is with minimal to no usage. I dont get it. Is it a software issue, there is no reason cell standby and bluetooth should be usaging so much juice with little to no use.

Root your phone, after that install Titanium Backup from the market, and once you load titanium backup, you can actually go to Backup/Restore and find the app that you want to freeze, click on it and choose Freeze.
Once you install Titanium Backup - it will ask you for root rights - click on "yes" or "allow" (dont remember exactly which one it was" so you can provide root rights for it.
Anybody know of documentation on best way to calibrate the battery? I did 1 discharge - charge cycle... how many more do I need to do? Do they need to be back to back or can I keep it plugged in while using it today?

My battery lasts a little less than my NS or vibrant. It should at least give you 5-6 hours of HEAVY usage. I left the house yesterday at 10 and by 6 it was done. Since it's a new unit I used it heavy, plus I rely on it for scheduling and contacting clients about every 30-60min. I was also playing games on my breaks.
You probably have a bad battery.

I do seriously think that there are a lot of improvements that will come in a software update. The Cell and Wifi usage are ludicrous and it's probably a matter of getting the phone out the door with an update to follow.
This is only the second Tegra 2 phone to be released in the US.
2nd day with the G2X and the battery life isn't getting any better... If anything it's getting worse...
90% at noon and 20% at 2:40pm. Plugged in at 2:40 and now 20 minues later im back at 88%
Drains way too fast, and seems to charge even faster...
This phone is faster is every way compared to my vibrant, I just wish this wasn't true for the battery loss..
Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you
I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.
Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..
I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...
Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.
I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.
Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours

Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.
Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.

How long does 1 of those batteries last?

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

does the royal ginger gets the same battery result?

Better than what's reported under CM7. The battery life I posted above was on RG.
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.
Hello, I'm currently running cm 9, however the battery life is just awful
When the phone is on sleep it loses like 1 percent every 5-10 minutes
I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal
If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.
alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe
OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb
Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting
If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up
Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.
Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep

Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.
