I am using the set up in my signature and I am getting horrible battery life. I might change roms (as you all know) because of this...it sucks. What can be the cause of this? I have had my evo for 10 months now so I am wondering if it could be my stock battery. It could be the kernel? Who knows...
Here is some information:
No wake lock problem
Wifi at home
3G outside
Calibrated it once since I flashed this rom
Battery decreases 3-4% overnight when sleeping
Moderate to Heavy user: texting all day, 2 hours of internet, XDA, constant emails, news, engadget, and youtube
I can see the battery life decreasing at a rate of maybe 7-10% per hour when I use it
Starting to decrease much more than it used to
***Picture: Subtract 7 hours from the 18 because it was sleeping overnight***
Any suggestions would be appreciated. You guys have provided plenty of insight for me and I thank you all for that.
Your battery life actually isn't that bad depending on how much you use your phone. Buy another battery on ebay and see if that helps. If you're looking to compare usage, I'd buy a stock battery instead of a cheap Chinese one, that way your tests will be accurate.
If your battery life just sucks and you want more juice, buy a few cheap batteries and an external charger and switch batteries when you get low. That's what I do, and it's great not having to turn radios off or do other tricks just to last through the day.

You can try changing roms...I get 1day 5hrs roughly on CM7, stock battery. For how're you're using the phone, that seems about decent, in my opinion. As plainjane suggested, you can get some other batteries and swap them out.
Youre lucky! MY battery lasts like 6 hours with moderate use

With that battery life? Perhaps, but never in my days of rooting have I run CM6. I'm pure CM7. Not biased by any means; I've tried some things, but CM7 is my preference, and if you want a screen shot I can provide.

Sure a screen shot would be good. Don't get me wrong, I like CM7 but I read CM6 with the snap kernel provides amazing battery life. To each his own I suppose.

I don't have the newer one, as my phone is in the middle of doing some things, but that kind of battery life is attainable on CM7.
I'm having problems too... I'm running on Myn warm 2.2 rls 5 and it's not charging anymore! Battery life also sucks ass too! It's getting worse by the days. I plugged my phone in to charge last night, and woke up to 26 % WTH!? I don't know if it's my battery or the rom. Help?

It could be your charging port. Those things break way too easily. When it's charging, check it every few minutes to make sure the charging light is staying on. One of my Evos had a bad port and when it first started happening, I would catch the light turning off then back on.
It could also be your battery. If you have another one you can test, see if it's any better. Or you can take the battery to Sprint and have them test it. Replacement batteries are pretty cheap if you get them on ebay.

Hey, thanks for the suggestion. I sure do hope it's the battery. I mean I do use it quite often to watch movies and what not so I'm not surprised if it's bad but I know it can be the port too because lately it's been acting crazy on me. Sometimes the light will be on, but it really doesn't end up charging. I don't know what it is. So if I take it into the sprint store to check the battery life and they won't say anything about my phone being rooted? Lol.

Anybody having trouble charging their phone to 100? My phone says it charges to 100 then beeps then when I unplug it, it immediately goes to 97. I have heard samsung phones have something that prevent them from charging to 100 or something like that is it true?

I am having the exact same problem and can't figure it out. I try to recalibrate the phone before as soon as I unplug it, but it drops down below 100% as soon as I unplug it from the wall charger that came with the phone
This JUST started happening to me this morning.
My phone has been doing this for awhile just keep an eye on how long the battery lasts if its still the same then no worries otherwise contact service provider

I get to 100% from both USB and the wall chargher (although I don't use the Samsung charger, I use one from a Bluetooth).
After unplugging, I stay at 100% for a few minutes, then it drops to 99%... Which makes sense, because the instant you unplug it, its obviously not charged 100% anymore.

Well are any of you rooted? You should state the condition of your phone when you have questions like that. It will surely help speed up or help with the answers.
Mine always drops straight to 99 the second i unplug it. Im not rooted. My battery life has been pretty good so i didnt think anything of it really.

And the reason I've had the phone for a week now and it just started happening this morning?
(not rooted)
Phone not charging to 100% is actually a good thing.
There's a website I read I think from this forums in another thread or somewhere else but basically explained how lithium batteries work. In it, it explained how manufacturers are encouraged to program their devices/chargers not to charge 100% to prevent over-charges. Doing this actually extends the battery life and efficiency. Its also bad to discharge batteries down to 'critical' levels. It defined critical as being anything under 20% and is recommended to recharge phone using outlet than USB at those levels. Anything above 20% is ok to use either USB or outlet and prefer with phone off.
I can say I saw the same thing happened to my phone where it was charged to 100% but once turned on its actually a little under that. I thought this was related to the "Android OS" battery bug but it isn't.
I charged mine to 100% then booted into cwm and wiped battery stats rebooted and it said 95% heres to hoping I get that extra 5%

When I had the motorola photon it did the same as well as the nexus I had. I think they do this so the phone doesn't over charge. But also if it's just started then you may have the battery drain issue I saw on here. I don't have it so I have no idea where it would come from....

You flashed different kernels when rooting, different battery stats shown in each. you should start to worry when your battery shows you at 100 for a while

What part of he's not rooted did you not understand? He's asking if Samsung phones are supposed to reach 99% immediately upon unplugging as stated earlier in the thread, then why his only started to do so recently. Nothing about flashing ROMs..
I've bumped because I noticed this phenomenon only recently on mine and think I recall it sustaining a 100% charge in the past. So it may only start happening as the battery ages: for some, like oosoul, after a week, and for others, like myself, after over a month.
If anyone doesn't drop to 99 straight after unplugging, can you post how long it stays at 100? Thanks

It's not a feature.
It has to do with battery calibration. You should be able to fix this by draining your battery, then going into clockwork and deleting the battery stats, then re-charging it up all the way.
Mine was originally charging up to 100%, but then after I flashed a rom it charges up to 99%. I haven't bothered to fix it because it doesn't really matter, but the same thing happened with my Evo and that's how I fixed it.
I do realize that everyone is probably going nuts playing with their new units and draining the battery life mad but I figured we start a thread to get general battery usage times from owners. We could also come up with a format that's acceptable, I'll start with this but we can change it as we go.
Link for app no longer works but here's a quick search result from the market:

There is a battery saving mode that is included with the phone under Settings.
Because of the Super AMOLED display, darker colors use less power. Therefore:

try SETCPU since you are rooted
make a profile for screenoff (i use 594-128)
that way when your phone sleeps the processor slows way down and doesnt use the battery as much
also if you meant when you sleep.....whenever you can.....use wi-fi and turn APN data off. That way the phone isnt searching for a cell tower constantly and using battery.
Hope this helps....PM questions

FOR 100% NO DRAIN ISSUE
ralnee said:
Okay.. I finally have some answers. I registered my phone on the Samsung site, and got into a live chat with a rep. I explained to the rep (as best as I could) that the battery usage was not updating once it reached 100%, without a reboot. After going back and forth (did you try A, yes I did, did you try B, yes I did...), she finally gave the the number of their "dedicated Galaxy S phones voice support team at 1-877-EZ2GALAXY (1-877-392-4252)".
I called the dedicated team and was finally told that this is a known HANDSET ISSUE, and to replace the phone.
I'm performing a full backup using Titanium Backup as I type this, then I'm going to do a NANDROID recovery (I think) and then reset the phone to factory settings. Then I'll replace the phone at the tmobile store I purchased it from.

Sure, and actually any battery app widget will show the battery level. The Nexus S stops charging at about 96%, so when you would unlpug the charger after it says 'charged', it immediately drops to 95-96%. I ended up buying a couple extra OEM batteries and a wall charger for them so I could pop in 100% charged batteries. Plus it made it so I never have to waste time charging my phone. When the battery dies, I swap batteries. Since this is the same 'family' of phones, I am real curious if the SGS2 does this also? Someone please confirm. Thanks!

I've read about this too, I thought they adjusted it on the software side though (so 100% displayed wasn't really 100% but actually more like the 96-97% of the actual charge on the battery, hence the calibration. I might be wrong though.

It does charge to a full 100% and gives that familiar notification that the battery is fully charged and to unplug it. It drops right to 98% after a few minutes though. Haven't really paid much attention to it just this once.

I can confirm that I have seen this as well.
Can someone pull their battery cover and post the OEM battery p/n? If I get this phone, I will most definitely order some extra batteries and a wall charger. I get 2-4hrs more battery life in my Nexus S charging them to a full 100% in the wall charger and will likely have similar results with this phone. Thanks

I've had this phone for about a month. Started off on stock, and rooted it and flashed different ROMs and kernels. I never really got good battery life with any ROM. Typically I would get around 7 to 10 hours of moderate usage.
I fully went back to stock firmware and kernel using ODIN, to flash 2.3.6. I rooted it and removed some bloatware apps. BUT, the battery life seems so bad.. it's been 2 days, I've done calibration 2 or 3 times.
Leaving my phone idle, in one spot, I lose about 4-5% an hour. 4G Data on, wifi off, 2/4 bars of signal, sync on (only gmail, google docs, contacts, calendar).
But today, I think it got worse, as shown here: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230121.png
Graph: http://i51.photobucket.com/albums/f380/wordk4/SC20120319-230126.png
Note: the data icon on top shows that it's on 3G, because I moved out of good signal area when I took the screenshots. The phone was idle in a spot with 4G getting 3-5mbps.
What's wrong with this? The phone is a month old, so I don't think it's a battery problem. I've calibrated 2-3 times since I went back to stock.
Also, don't recommend me to use Juice Defender. I use Google Voice to call and text, so I need data on all the time. And I know this phone can last over a day with data on (my friend has the same phone and it has lasted 2 days on one charge, completely stock firmware).
ALSO, when I press "Android System" on the battery history, here's a list of what it shows:

I see easily over 12 hours on a charge with my phone, and i use it heavily... 2 to 3 hours of phone time (at the least) wifi tether here and then, a lot of facebook iming and checking. Reading....
Something i noticed though. I got the phone in October or so, and the battery life started off pretty bad. I didnt do anything special, i figured it would be bad with such a massive screen. Over time though the battery improved, and now im seeing wonderful battery life. I usually unplug it at about 6:30 or so in the morning when i head to work, and yesterday at 10-something is when it started *****ing it had low battery life.
Moral of the story? Be patient, itll get better as time goes by.

Your battery looks fine. Playing games rapes the battery. Also 4g rapes the battery.

Something is definitely draining your battery. As you can see your phone is awake when the screen isn't even on. It's just likely an app you downloaded or something in the background. good luck narrowing it down

Something i noticed though. I got the phone in October or so, and the battery life started off pretty bad. I didnt do anything special, i figured it would be bad with such a massive screen. Over time though the battery improved, and now im seeing wonderful battery life. I usually unplug it at about 6:30 or so in the morning when i head to work, and yesterday at 10-something is when it started *****ing it had low battery life.
Moral of the story? Be patient, itll get better as time goes by.

You give me some hope. I recently ordered an Anker 2050mAh battery for this, hopefully that will help in the meanwhile.

2050mAh wouldn't get you to much more out of thr battery..
Only 200mAh over stock, hows this supposed to help if you have a sleep mode issue or app issue?
Bringz me back to my first statement.
Your kernel is NOT allowing deep sleep mode for whatever reason, your best bet would be make a backup
Delete data/factory reset and try it over a day.. if it works good, its an app issue, still the same. It is undoubtedly the kernel. Why pay more for maybe an hour out of your phone?
Run some actual tests to clarify the issue first..
There. I said my peace
If you tried everything else try recalibrating the battery.
I have seen this happen most often when flashing new ROMs. Especially if you did not wipe your system, data, and caches before install it seems to encourage this.
To Recalibrate Battery (must have custom recovery like cwm):
Charge phone to FULL
(I highly recommend AC charger for this)
Reboot into recovery
Look for wipe battery stats (should be I'm advanced if not main menu)
Unplug phone and restart it
Now FULLY KILL THE BATTERY
(for faster results set mp3 or video on repeat and let her rip)
Fully charge one more time and done
(again I highly suggest AC adaptor)
Keep in mind if you set your CPU to Max frequency or leave a demanding app running and CPU is set to allow full usage ondemand or performance the phone will kill battery very quickly.
Same if you leave antenna on auto 4G and it is weak around you and phone is always searching it will go fast as well.

You sir, are a n00b, calibrating the battery is useless to this device and actually done automaticly.
So your post is useless and rather a waste of everyones time even reading. So thanks.
@above
Its obviously not hitting deep sleep, there's no way it can be and be draining the battery this quick.
@OP
As suggested above use cpuspy to check on the cpu when idle,
Sleep mode should kick in within 30sec to a minute.
Also chek my reply a few posts up and follow steps there..
Ignore Realn00b's post
Again:
@Realn00b
Please take the time to read up on batterystats.bin and find out what its for,
You don't need cwm to delete, just root explorer.. its in:
Data/system/batterystats.bin
Also, the entire basis of this is stupidity and was takin way out of context.
Batterystats is used to cache the active information of running applications (uptime/cpu usage, etc. NOT battery percents)
And should only be deleted under very very rare occasions (effecting above)
Your battery percent, is actually the mAh
Your system collects the information from a chip on the battery, among the information read, max mAh and current mAh.
The device then calculates from these the value we know as the percent.
Meaning, no device with a lithium ion battery stores charge information for the battery, making the entire purpose of your post for this, or ANY device not only useless, but also a little pathetic considering you would actually try to post a tip on something you are obviously completely uneducated about.
Please don't provide tips unless you are 100% sure of the situation and are actually educated on the material. Thanks

I originally purchased it for two reasons:
1. For long trips or for when I'll be gaming a lot
2. It had no reviews, so I figured I should buy it and test it. It's cheap anyways, $11.
Also, I'm on stock kernel. Everything stock + rooted.
I just did a re-flash with ODIN, so it has all the bloatware back on. I rooted and installed most of the main apps I use (facebook, aim, xda, google apps, games, basic things).
Currently I have sync on for Google contacts, calendar, and gmail. Facebook syncs with existing google contacts. T-Mobile contact sync off. Dropbox auto uploads camera photos on wifi only (I rarely take photos).
It's charging right now, at 50%. I might not have time to leave it idle today, so I could try in the morning if I have time.

Yea your right that is a good price.. is it same size as stock and have NFC? can you post link?
Thanks.
And please excuse realn00b up there..
He didn't know wat he was talking about.. read my post below it if you want an explanation.
Take a look at the safe to remove apps list aswell I'll see if I can find it on google pages for you. I definitely recommend
Deleting unndeeded applications and even replace stock with third party where applicable.

As many of you guys here have seen, there are a bunch of intelligent folks on these forums. Many that have massive hours on their battery. I see screen shots with 17-21 hours average. And to make things short,I wanted to find some tips on how to reach these incredible hours. if you guys don't mind sharing the steps you use when flashing a brand new rom, also what battery you use, what zips you flash, what settings do you turn on or off. Just things like that. Im using the universe rom with the diet pill rc1.zip placebo. My battery is a slim 2500 galileo. I don't use 3g data so I turn it off in data usage, when I do need data I use my 4g. Im seeing around 10-14 hours on a very conservative day. I like my phone so I use it heavily. Also what governor and cpu settings do you use along with what app, (set cpu, antutu, no frills,etc.) any different kernels? Any links would also be greatly appreciated. I understand all phones react different to different things or scripts ect. Im just wanting to get a general idea of where im going wrong. I know my way around the root explorer and terminal emulator and odin/mobile odin, and setting permissions. Might not be enough but it's something to get started right? So like I said before any help is greatly appreciated.
One ritual everyone should have is getting a new battery after a year . I mean personally I am used to taking care of lithium ion batteries so they last upwards of 3 years. But its likely most people don't keep their phone charged and allow the charge to drop to low levels frequently. I know some owners that got their phone at launch have already fried their batteries. Just hope no one wonders 6 months to a year from now why their battery life sucks.
I had 36 hours at 33% on my day off 3 days ago on a cm9 nightly, 2 hours of screen on time. Usually my day off times on any given rom is around 30 hours. I can pick up any one of your phones on any rom and kill the battery in 6 hours. Plain and simple this phone doesnt survive more than 6 hours of screen on and use unless your displaying a black image (no backlight on OLED, black = 0 to near 0 energy so just whatever the phone being wakelocked uses) and or use an extended battery I get 8 to 12 hours of frequent use out of my phone every day.
If your extended is worth a damn you will get more. Having trouble finding this battery. But if it fits in the stock case it is not 2500mah. Most of these cheap Chinese batteries are not worth crap and the first sign of an extended battery being junk is not needing a larger case.
Here is the battery im using, just got it on saturday. So im still letting it drain all the way down. One other thing when it dies,I charge it to 100% then calibrate it with the battery calibration app or what do you recommend? http://item.mobileweb.ebay.com/viewitem?itemId=221047292497&index=3&nav=SEARCH&nid=69261834567

I have the diet pill installed. How would you recommend I install it, download to my pc then copy it to my phone and flash with agat? because I just downloaded directly on my phone and flashed with agat. And placebo forum has like 10 zips which one do I use? Would you mind sharing the zip?
@rudyrude432, How's that battery working out for you? Can you give some info on your usage and how long it lasts for you? Thanks!

Well it looks to be holding up well but I have only had it since sat. It looks promising but some people think it might be a piece of crap. But I bought it and now it's mine so let's see where it is once the kernel and rom settle. yesterday I got around 8 hours with 60% left
with little use and no data on, only when I needed it which was about 30 minutes. I usually use my tablet on the weekends so blah blah blah huh

Stock size battery. There is no way that is 2500 mah. Most can tell you your lucky if that is even the stock 1800 and at the price of an oem Samsung i would hope it is.
Not sure why some take the risk. The chance of fire from an unstable cell is bad enough with oem sourced cells out of china. Trusting a 600 dollar phone my skin and pants to a random liion cell is not something id want to do. You get good ones and sometimes there comes a point where there are no other sources (older devices).
I wasn't going to say put it to the test. I would normally leave the battery guys to this one. But I noticed there is an app that measures drain like an amp hour meter should. I would say check out the app in this test thread for an evo - http://forum.xda-developers.com/showthread.php?t=1176984
Wish I could find that link to the test of the popular extendeds for this phone. Almost none of them were near their rated capacity and were talking batteries that had casings with the potential to hold a cell with the rating. Not a stock size case in which I quote the popular phrase "Anything marked 2000 mah is a fake"
Cant find much on the cell for this phone but another evo thread on another forum came up with stuff like this:
eBay: Galilio 2500mah SLIM
= sticker pull reveal only hd545148ar and 11F18NF1700, suspect this is 1700mah

As long as it works at stock capacity and as long as it doesnt pop. The price is right who cares. Not beating it up on those notes. Beating it up for its miraculous 2500 mah. Silver Zinc sure but not liion.

I understand where your coming from, that's fine and all,I mean even with the stock battery im getting the same or less amount of hours,idk what's up. I'll buy a new battery that is Samsung brand and test this phone out again. No worries, my main reason for this thread was to learn some tips and tricks that people do when they start with a fresh rom. That's all no more no less. But I do understand your argument with the actual battery itself. Thanks for the heads up again.

in the terminal... type in SU
then allow it super user permissions if a box pops up
then type Black
or type Black2
(caps sensitive... make sure its a capital 'B')
Black = more performance oriented
Black2 = geared towards battery savings
then check the log files for any errors: \system\etc\log
gear01.log is for Black
gear02.log is for Black2

I really appreciate the quick responses, you guys are great, one more thing do I download with the pc or is it cool to use the phone browser and can I use agat recovery to flash it? Which I already did.
Might seem obvious, but have you tried juice defender? There is an option to turn off mobile data when the screen is off. Also disabling auto sync for Gmail has made a pretty big difference for me. Automatic brightness, and set the screen to stay on for 10 minutes (I find that I save battery this way because I read a lot, and constantly unlocking the screen causes more battery drain.) I'm on cm9 a6 and my battery lasts pretty much all day, much better than "stock" cm9.

I like to download from the PC to be safe and then transfer it to the phone via USB. but for tweaks such as placebo, downloading from the phone should be okay. They are small file sizes so less of a chance for corrupt downloads
Agat recovery is perfectly fine to flash it with.

So flash placebo black, type su
then Black2 (battery saving). Check for errors and that's it?
Right I'm confused now, having the batteries fully discharge is bad? I usually fully discharge and fully charge my battery.
