Also when it's green doesn't mean it's fully charged.

theres 2 main questions, are you using sbc or a wall charger and two, who makes the battery

and if its a non-seidio, some of them just plain suck. i've bought 4 different ones from ebay/amazon only one actually works well after calibration and many cycles of usage.

I am usung netarchy sbc

You need to condition your battery
I've been dealing with this for ever and I thin kI finally haqve a routine figured out that is getting me CM7 like battery life on a Sense ROM.
1st, I've had the Sedio 3500 for a few months, and like you, I was getting ridiculous drain, until I started sdoing some reading and experimenting.
Here's what I do.
First, off, I have GPS, WIFI and Data disable all the time, unless I need one of them, and then I turn off again when I'm done. I keep my screen off all the time, unless I'm using the phone. I also only use minimal widgets. Calender, Fany Widgets Weather and Forcast, Messages widget, the Beautiful toggle widget for silence and my MIUI Music player on 3 screens, using Rosie. The other 4 screens are just empty.
Second, as for the battery itself, charge the phone for about 8 hrs, and this is the HTC method, unplug it, turn it off, and charge it for another hour, while off.
Unplug it, turn it on for 2 minutes, then power down and plug it in for another hour.
Now, before powering I up, I do the Hoodoo-voodoo-like 10 time unplug thing.
Basically, unplug, light goes off. Plug it in, light is red, wait til it turns green, unplug it and do this 10 times.
Reboot to recovery, wipe battery stats, power up, all while plugged in, and once fully booted, unplug.
I did this today, using the new Koni 3, with Netarchy 4.3.2 SBC HAVS, and riding then used the phone pretty steadily to play Klondike, text, etc an an hour later was just dropping to 99%.
THAT is pretty good, compared to what it used to be like, when it would drop about 1 percentile per minute, even when it was in sleep mode.

Reconditioning is not going to work when you buy a crappy battery. Someone said voodo? You're kidding, right?
Please understand there is no regulation that prevents people from stating their cheap batteries on eBay are 9800mAh but only providing 1000.
I bought 1500mAh eBay batteries that are only 900mAh, verified with equipment.
Check www.batteryboss.org to see what I'm talking about.
Best thing to do? Buy a $1 battery wall charger, two OEM/non-generic htc batteries and carry in your wallet. I wouldn't be surprised if your 3500mAh battery actually packs less juice than the original battery. Oh and your phone is looking like a brick for nothing.

yeah this is why i asked, if you bought a very cheap extended battery, well its rating is different than what it is providing you with

I think I have battery problems solved; Just turn Data off when you're not using it. My phone has been off the charger since Friday night @ 6:30pm. Now it's Sunday @ 9:30am. That's 39 hours and I'm sitting at 63% and I've been texting, making calls, playing a few games, and anytime I need data, I just turn it back on til I'm done and then back off again. That's the only thing I'm doing different now, and before I made that little change, my battery was a good or bad as anyone else's

When I am home, I have WiFi enabled all the time, no 3G/4G. I heard WiFi is better(with good signal) for your battery than 3G enabled. Is this true? My battery lasts about 7-8 hrs of moderate-heavy usage.
Also, here's a thing with all of you trying to tweak your battery to get best performance. From my own experience, I am never a step or two away from a charger be it while I'm on my computer at work, at home or in the car. So what good is it to have the phone out of the charger for days?

I understand WiFI is better, too, from what I've read.
Also, if I can find it, I found a thread on androidfrums from htc that recommends you let your battery drain to below 50% before charging it.
Like you, I have chargers all over, so it's not a big deal, but to be at where I am now, with this experiment on turning data off is simply amazing to me.
Almost 42 hours and at 59%

That is definitely a huge performance improvement but I wonder what's happening with all your apps that need the data sync in the background. I have apps like Pulse, Facebook, K9, Handcent, etc that update every couple of hours or have "push" enabled. What is the trick to allow 3g, 4g, wifi to be enabled automatically only when sync is required and then disabled?

Good question.
All I use is the weather bug and Fany Widgets weather, ad far as widgets that need updating. I think, once they try to update and can't connect, they "freeze" for lack of a better word, until you reconnect and manually update.
It's a little bit of a pain, but for this kind've battery life, I'm not gonna complain

I think what would work is an app that puts the phone in "Airplane Mode" (bad Moment memories ), but allows the calls to come thru. This way there's absolutely no Internet traffic but your Evo is still usable as a phone.

That's probably, basically what I'm doing, but like you, coming from the Moment, Airplane Mode is a bad word....

[Q] My Stand-By time is about 10 Hours

If I were to leave my phone on without using it, it would die in about 10 hours. Is this normal? It's been like this since stock. I don't think this is normal since my G2 had way better stand-by time.
Please, don't say it has something to do with your settings and stuff, because I had the same things turned on with the same apps on my G2 with way better Stand-by time. GPS and Auto-backup.

Im running bone stock. I recharged after 38 hrs. And still had a 30% chg left
These were 14 hrs after complete chg.

See? This is what I'm not getting. Even since stock my Standby time was horrible. So I rooted to get better battery life. Nothing is changing. I even did a battery calibration to see if the phone was just reading the battery wrong.
I have another question. After the phone is finished charging at 100%, as soon as I take it off the charger, it goes down to 99%. Is that normal? I thought the phone was supposed to stay charged at 100% for a little while.

I just unplugged mine from complete charge and as soon as I unplugged it went to 99. So, yes????

That is normal to drop to 99% immediately. I always charge to full before I go to sleep at night and for some reason if I leave wifi on, the drain is really low when not in use...

Ok. I have no idea what is going on, but my phone just randomly rebooted, froze and then reset my home screen replacement launcher (as if I hit set to default), and now when I went to check on the battery usage and this is what I get:
Android OS is now at about 2% along with other things.
Display is at about 50%.
This is new. Android OS used to ALWAYS be higher then display. That didn't make since.
Now things are different. It seems the display is using the most energy. That is normal. I expect that.
I don't know, but it seems that everything is back to normal. I am using the phone, so I'm expecting this battery drain, but I'll check to see how much battery is drained on stand-by when I go to work later on today.

If you want your phone to last you throughout the day, make sure that "Use Wireless Networks" in Settings -> Location is unchecked. That is the biggest battery guzzler this phone has next to 4G and Brightness. My battery loses 2% all night til I wake up (Thats 8 Hours!!)

I figured it was a Samsung thing. I leave GPS off if that's what you mean, but location services stay on. That's just a me thing.
///////////////////////////
Today after work, I lost 30% energy on standby. That's alright with me. It was about 6 hours of straight standby time. It seems to have gotten better. At times I'd lose at least half of my battery after at least 5 hours.
I don't know how the phone seemed to fix itself, but doing things doesn't just DRAIN the battery anymore. I was playing on the phone fixing my home screen launcher and my battery wasn't dying right in my face. I lost like 2% after having the screen on for about 20 minutes fixing up my settings compared to seeing 5+% in like 10 minutes.
I am satisfied.

Lol, your battery didn't fix itself, that sounds like somethings wrong with the battery cycle. Maybe you need to recalibrate it.
You see, sometimes if you overcharge a phone, especially when using a charger that isn't made for that specific phone (usually a charger thats too strong) it can throw of the charge cycle. Thus, it can take like 30 minutes to drop 50% and then another 3hrs for the other 50% (this is just an example). If you're rooted, I highly recommend doing a full battery calibration.
Secondly, the Use Wireless Networks thing in the location isn't really a samsung thing, i think of it more as a google thing. I noticed that when its on, Google is always sending information back to itself, thus keeping the phone awake longer. Thats why if you go to your graph, it show that your phone is awake more often then it should be. I personally uncheck it, because if i ever need it, I just quickly switch on the gps. Then turn it off when im done.Thats my recommendation to you. Yesterday, I personally got a full 24hr usage out of my battery, and it wasn't even all that light. I texted most of the day, made a few calls, browsed the web, and listened to music for a few hours on the subway. Pretty moderate usage.

See, I'm not exactly unhappy with my battery life... but seeing what other folks around here are getting MAKES me a little unhappy.
I mean, I went to bed at... I'll say around two AM last night at 90% battery. My audio book player ran for thirty minutes after that; woke up at about eleven AM, 53%. NOTHING CLOSE to what you folks are getting. All of the big culprits I've heard mentioned have been checked out, and I just calibrated, so I dunno where else to go with this.

Does anybody see anything unusual about my battery life?
My screen has basically been off, yet I'm still losing weird amounts of battery. Based on the hours, I took my phone off the charger at 4pm Dec. 04 (16:00) and it died at 6am (06:00) Dec. 05. That gap in WiFi was my time at work.
Those bars you see in display right before WiFi get's turned on is me texting and Facebooking. Apparently I wasn't using Facebook enough for it to actually get a place in my battery usage.
And of course those two little bars in the red was my phone telling me that it's dying. Too bad I was sleep.
Ignore the rise after the fall. That's it charging of course.
Also, if you notice, my WiFi apparently wasn't using anything to get a place as well. Those are all the apps that were listed. Why isn't WiFi there?
I calibrated my battery twice already. I can calibrated it again since it fully died. Let me make sure I understand how to calibrate it.
ROM: ACS Syndicated Ice
Kernel: LoS Kernel
1) Phone charged to 100%
2) Phone dies
3) Charge phone to 100%
4) CWM and wipe battery stats
That's what I do to calibrate it.

Add a 5th step which is using the battery calibration app from the market. Also, uncheck wireless networks from location settings (huge battery hog). I assume that's probably your biggest problem. Then, if you are rooted, do what I did, which is get a root explorer and go into system>apps, and move the social hub.apk and media hub.apk to a folder on your SD. It will essentially uninstall it. Those 2 apps are battery hogs as well even if you have never used them. They will always run in the background. Try those and lemme know if it helped.

Wireless network location settings is also mainly used by Google to send them data about your usage. I noticed a significant decrease in battery life whenever this is checked. I would rather just turn on my GPS whenever I need it than keep this function on at all times. Its just not worth it in my book.

Horrible battery life while just being idle?!!?

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:

Actually that would be more of light/medium. Checking facebook every 30mins, a few texts now and then, playing a game for 30 minutes, listening to music for an hour, a call or two about 2mins each, a few instant messages on facebook, GPS use for 5 minutes, and idle for about 5 hours.

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.

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

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.

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

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

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.

4G Battery Drain

Hey, im on Telus so i dont have any other modes I can switch to to lower the drain. Ive noticed my battery drain is HORRENDOUS
Over the past 4 hours ive dropped 60%!
Now im wondering if im just running too many apps or if my stock battery may not be holding a proper charge anymore, and wanted to compare with others to see if others are running the same amount of apps and getting better battery or what
Ive got the following on:
Trillian (IM app)
K9-mail checking 2 aps
Regular Sync (Twitter, FB, Dropbox, Google(Calendar, Gmail, Contacts)
The battery usage summary seems to lie, 35% is the screen but only 13 minutes. Yet im at 40%
Android System at 20, Cell standby 13, Phone Idle 8
While heading to work, i ran DI Radio(music streaming), and lost 20% over around 35 minutes.
Im using the Tuesday rom with it's default kernel.
Is there anything I can do for better battery, because I dont have wifi in most places, and im running 3-4 bars constantly yet the phone just drains rentelessly. Even my Mugen battery was only lasting 16 hours...

It's quite possible that it's the ROM. I used to always get 8 hours on a single charge, regardless of location or ROM. I'm running Eugene's CM7 and I'm getting 13 hours on the same typical usage.
I'm running on Telus as well, with no wifi at all.
Although I am not running all of your apps, I would still consider myself a moderate to heavy user.

Seems rather sad that the phone can only do 8 hours on a charge. Im going to restore my juggernaut and see how that compares i guess.

Yeah, I know how you feel. Just experiment other ROMs and see if you get any changes.
How much usage would you get out of juggernaut?
Sent from my Samsung SGH-T989D using xda premium

Its been a while since ive run juggernaut. But it used to only drain 10% an hour i believe on 4g. I've restored my nandroid of Jugg and will be monitoring that.

any syncing or usage of the network will take a drain. any usage.
you can always turn on airplane mode and let it sit a few hours and see the drain, that determines whether its network or a ROM/kernel drain.
But yes, using 4G has big battery cost

Battery Life
I will tell you what, I have wasted so many hours playing with different ROM's and what not to find the one with the best battery life. And I will tell you what, the DARKSIDE:IGITAL::WARFARE ROM's out do any other ROM out there. I dunno what it is that thederekjay is doing, but Samsung should get this guy on pay roll because his work is the best.

I'm at hour 8 today on Darkside Digital Warfare, and 70% free from 8am to 4:30pm. I have push corporate email, automatic brightness, friendcaster push, and a slew of accounts and it runs like a champ with amazing battery.

Make sure your phone is going into Deep Sleep as often as possible when screen is off. My phone seems to be extremely picky in regards to which charger it likes and more often than not (even had this happen on the stock charger) the phone refuses to sleep after being charged (even if only for a few seconds...).
Download CPUSpy from the market and after each charge, go to CPUSpy, press menu and Reset Totals (phone cannot enter Deep Sleep during charging so it's important you start fresh after a charge to get accurate sleep time). Turn the screen off for a minute or two and turn it back on. Press menu again and Refresh Totals. In my experience, if the phone is not sleeping at this point - Deep Sleep showing in Unused States - then it will not sleep all day and remain in 384Mhz for hours, killing the battery rather quickly. From then, if I plug the phone in a supported charger (even for a second) and disconnect, Deep Sleep resumes normally. Rebooting always fixes it too.
If, like me, a lot of people also have this problem with the stock charger as well, I bet many are dissatisfied with the battery performance... The phone is supposed to spend the majority of it's time in Deep Sleep. I get this issue with several different chargers and cables and on different ROMS / kernels (including stock... go figure).

Im pretty sure its the signal itself draining it. It uses sleep for at least 40% of the time its on. I use my phone a good amount, but its the fact that if it sits on 4g even with the screen of, its rapidly draining during this time. ive even reset timers and left it sitting for an hour and itll be in sleep but lose 8% over an hour just doing nothing. I still wanna be able to recieve notifications tho so turning off data isnt an option. I will test turning off data anyways to see if the drain stops.

The battery drain is all those persistent internet apps running. That is what you call heavy usage. Trillian and the FB app being the two biggest. Music streaming would be up there as well if you aren't in good signal area. Look at your battery stats and see what your signal strength is.

I second this. If battery problem persist download better battery stats to see if you dont have any kernel wakelocks

[Q] battery drops as soon as i unplug

I just got my gs3 2 weeks ago. Since last week, whenever i unplug it from a night of charging, the battery immediately drops to 98%. I had rooted my phone, but i restored it to like out of the box this past weekend. Is this a known bug?
Thanks.

I don't think the batteries charge past 98% as a fail safe mechanism.
Sent from my SGH-I747 using xda premium

So the 100% is a lie?
also, what's odd is that if i unplug it initially, it drops to 98%. if i plug it back in for a few minutes and then unplug it again, it's up at 100 and seems to drain relatively normally.

The battery life on this phone is a bit of a mystery..I have had mine replaced due to just horrible batt life. It would drop 10% with about 10 mins of browsing. The replacement has been marginally better. I have no idea how people are getting 4 hrs screen on time with 20% left. I just flashed the MIUI JB4.1 Rom and its still not any better. Makes me think I have purchase another batt...

A common problem with the battery life is an error with account synching. Every few phones will have this issue, and it is easily fixed with a factory reset. Basically the phone will try every 3 seconds or so to synch your accounts only to fail, and try again. Causes the phone to drain in less than a half hour.

If i flashed a custom rom, I would've already factory reset though...

I retract my previous statement, I obviously don't know how to read.
Still, doesn't hurt to check. Go into your settings and check your accounts. If any of them have a red error symbol when you click on them then you may be having this issue.

It's possible. I got pretty close to that yesterday but that's being connected to wifi all day at work and at home and no videos. It's possible doing very minimalist tasks.

Imo, battery life on this out any around phone is not a mystery. Auto sync, auto bright, auto rotate, anything "auto" will cause more battery to be used. I can also tell you that simply hitting the home button to leave an app, instead of using the back button, will cause more battery drain. Wifi uses less battery than mobile data. Bluetooth will also cause a slightly higher battery drain. Email, or any app, set to push will devour a battery. Leaving apps open when locking the phone will cause slightly higher battery drain. Leaving wifi turned on when not connected to wifi will also cause a drain.
I know a lot of that is what people consider a smartphone to be used for. But with a little tweaking, most can get their battery life better. I personally leave auto everything off, screen timeout 1 minute, screen bright 25%, wifi/bt on only when in use, email set to poll when i open the app. I think you get the idea.

Screen timeout means nothing. Just put your phone to sleep...

Yes the 100% is a lie. Most phone manufactures only allow the phone to charge to 96%-98%. This gives the life of the batteries longevity. When I had the galaxy nexus developers would add 100% charge into their kernels so those who wanted to fully charge their device could...
Also if you look at your phone right after you take it off the charger it will say 98% but if you let the phone sit it goes back up to 100%. Don't know why though. I am no dev just my observations.
