sudden overnight battery drain - Motorola Atrix 2

I know battery drain is a tough one, and I'm not looking for any easy answers. I had my atrix2 humming along nicely for several months doing very well with battery use draining 1-2%/hr while idle. If battery drain ever spiked after app updates, I could always get back to normal with a reboot. One day I rebooted and the battery drain didn't go away. The battery usage screen in GB gave me nothing useful (phone idle, bluetooth and cell standby are always tied for first place and no errant apps show up) so I opened Titanium backup and started freezing apps to try to nail it down.
Over the next few weeks I tried everything, but battery drain just increased to the point where it would bounce around between 5 and 10%/hr. Something was clearly wrong. I did a factory reset and that did nothing. I excluded all media folders from mediascan and even removed the SDcard and that did nothing. I even got a new SIM from AT&T.
Finally, I got a warranty replacement, and slowly reinstalled my apps via titanium backup, but the battery drain returned. I didn't have it completely bone stock for very long because I was convinced at this point that it was a hardware issue, so I don't know if it was draining like this out-of-the box. I figured the battery would need a couple cycles to settle in anyway.
One way I can get the drain to settle down is to turn on airplane mode, and then it does really well with about 1.5%/hr drain.
I'm wondering if this is something that either google or AT&T changed with their respective services that might make phones use more juice. Anyone else seen anything like this?

If, after rooting or more likely the case after flashing a new rom, you often have battery reporting errors, and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. I run my device in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day an a half to a day and a quarter of full runtime from my battery. This is with moderate to heavy usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps:
1. Take the case off your device (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your device to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your device completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

ive been waiting to write a new topic regarding battery drain since a while, but never got the time.
Apex_strider, I hope u can help me out.
Ive been having battery drain issues right fron the time ive bought the phone. never had more than 16hrs in an entire day after a full charge, and out of the 16 nine hours was when I was asleep.
ive been monitoring the battery drains from the inbuilt app and the main culprit is always mobile standby. never less than 30% n going as high as 39%. The 2nd culprit is almost always phone idle, which is a bummer. 20 to 30% of the entire charge.

(Mobile standby is the time when phone is on)
I had done the proper full drain n then the full charge cycle when I got the phone. got a new Sim card cause the moto service centre said so, still no help. That guy had suggested initially that there might be a problem with the motherboard, but later he suggested to get the battery changed, so I got a new battery. after that since vodafone uses a 32k Sim and since the problems I had while updating my phone, I got myself a new spare Docomo connection which is a 64k Sim(its written on the package)
now with the new non-vfne 64k Sim n fresh battery which ive been draining fully and charging fully. Theres been no change.
With Docomo
16hrs 45mins - Mobile Standy
12hrs 37 mins - Phone Idle
10hrs 20mins - Wifi
its 16hrs cos of late night charging the phone and after charging left the phone with wifi on.
Out of the 12hrs that ive got 8hrs 20min was when I wasnt using my phone at all! And this isnt just one day.. I use my phone mostly for surfing, IMs and occasional non-power consuming games. And as u can see theres not much of any power consuming apps from that list.
The whole problem comes down to either the radio hardware or my service providers (vfne n Docomo) 'service'.
My signal strength varies from 75db 19asu, 83DB 15asu and 91DB 11asu,n occasionally over that. And I vaguely remember vfne having the same numbers.
Now one thing ive noticed is that I dont always get all the 5bars of network and theres a lot of signal strength fluctuation even though the vodafone tower is right above my apartment.
Do u think it might be something to do with the fluctuating signal cause of which my phones radio has to constantly deal with finding a signal ? Or is my radio faulty ?
Btw when I was on vfne, my network selection was automatic and I used to get HSPA and now on Docomo ibe selected 2g, Edge.
to conserve battery, ive kept:
Battery mode to Maximum batt saver
Animations Off
Haptic feedback Off
Brightness is mostly on 10%
Use Wifi when m at home.
if its a radio issue dun think the batt calibration is gonna help me out.
any suggestions ??
PS: my phone is unrooted.

You have the same issue as me.. Try using SCv6, I used it and my battery lasted longer than any other rom, but I used SetCPU and underclocked to 800mhz using Moto Hotplug. You should give it a try , I went from 6-7 hours of battery to like 14-16 hours of battery.

He is unrooted, stock GB, so until (or if) he roots that isn't going to help.
To the OP, I can send you an .apk file I've used called CPU Sleeper, basically shuts the CPU down when the device is sleeping. May or may not give you much noticeable improvement, but worth trying. I'm still thinking of other possible solutions for you...

16% really isn't much. Think of it in terms of 16% of 100%, makes it seem less dastardly.

Well he's not looking for easy answer, but he might have a big change if he roots and use SCv6 and underclock to 800mhz, the device doesnt even become slow if you underclock, you wont see any difference cause of the speedy script and it's based on AT&T rom. So it might be good for him, because he is using AT&T phone I guess.

I'm sorry, I have to disagree with this. Either his battery is bunk, or there's something causing the drain. Rooting and flashing a rom at less than STOCK ROM CPU SPEED is asinine. So, aside from him buying a brand new OEM battery, the best plan of attack is to hunt down the cause of the battery drain... and fix it.

@darkmixta - ive an AsiaRetail phone so dun think att roms gonna help, actually dun think any roms going to help if its a hardware problem.
@Apex_strider - 16% drain after 12mins of talktime is a lot acc to me.
I wouldve rooted right away if I didnt have any issues with the stock phone and tried all the batt calibration n setupcpu apps, ive read about a lot many options I had.
But then I wouldve voided my warranty and if it did turn out to be a hardware issue then I would be stuck with it.
Ive even decided to get an extended batt fron ebay. But that wont solve my problem. And the new battery that I got was an OEM from the moto service station.

It is not like once you've rooted you'll remain rooted for life, the way you root same way you can unroot as well.
Go to dev section and look into my rooting method for more info.
So if you give your phone for warranty just unroot and uninstall the orher apps.
Root and try apex_strider method it works.

anikadam,
You're right, my apologies. 16% IS a lot of battery consumption from just 12 minutes of call time. I believe this was my 2nd oversight in reading and paying notice in the forum. Perhaps I'll take a short hiatus to avoid such embarrassment due to the onset of more sleep deprivation.
If you do suspect it's a hardware issue, are you going to try and replace the device altogether? No amount of attention given to your issue is going go do much good if, in fact, it is hardware-related. Is a return still a possibility for you at this point?

Can not recalibrate battery

Im trying to recalibrate my batter because of terrible battery life. After letting it die and charging it while its on I had no issues getting it to 100%. I powered down the phone to charge it while it was off and it seems like its hanging at the last percent and wont go to 100. I have had it plugged in for a few hours now and its still showing the same charge but wont fill up the last little bit of the meter. Anyone have any ideas? Im really thinking about tossing the battery and getting a new one. It seems like i got a bad one. no matter what I do i can only get about 12 hours of light use. I work 10-12 hour days so I have to constantly worry about my phone dying everyday I work.
I had the same issues. Tried every battery trick I found on the forums, but nothing worked. I went to ATT, they sent me a new battery and it everything's good now
So try talking to ATT and getting a stock OEM battery before you buy one
I picked this up and it gives a lot of peace of mind: http://www.amazon.com/gp/product/B004206TQ8/ref=oss_product

At first I thought it was the phones that vary in battery life.
My first captivate had really good battery life. But it bricked after I tried to do the JH7 update. So I got the phone exchanged, but they used my original battery in the new captivate. For some reason my phone was draining really fast compared to my old captivate, and this was weird because both used the same battery.
This was really annoying me cause I loved this phone, but the poor battery life was ruining it for me. So I went to an AT&T store and told them how bad my battery life was. They shipped an OEM battery for free and I've found a new battery to significantly work better than the old one
Hmmm. I just got a replacement phone and everything works better...GPS ect... but the battery was the same as it is now.....10-12 hours. I've been thinking about getting another battery but I don't know if that will fix the problem. I guess I will try to anyway.

How long have you had your replacement phone? I know my battery life got better after a few days with my original captivate
I got my replacement phone about a week ago...I've been trying to drain and charge to make sure the system is getting a good read....I've had the battery since launch...the only time I got great battery life was when I used unhelpfuls undervolting and the first time I flashed jh7. I have only flashed one rom on my new phone. It just bothers me that it drains 5-6% an hour in idle. I don't have any Widgets and the only thing that is updating is email once an hour

I somehow doubled my battery life. After draining and charging the last few days I managed to go from 12 hrs to 24 hrs of battery life while using it the same amount as before. I have had had my phone since launch and battery life sucked. I don't know it its because I got a refurbished phone that did it or what. I flashed my old phone almost every day for awhile. Even when I didn't flash I couldn't get it to last.

Good stuff, thanks
I've seen it and read most of the battery threads out there. I've come to the conclusion that: 1. There's a bad batch of phones out there that cause battery drain issues or 2. Since most of us ATT android users are new were unaware of the proper procedure to flash roms. I believe the second to be more true since most of the batterry drain issues happen due to flashing new roms according to most of the threads I've read. I would like to see the percentage of people out there who are still running there cappys stock with never Modding or flashing to see what type of battery life they are getting.

Before rooting, sideloading and flashing unhelpful kernel I was getting the same battery life, 10-15 hours depending on use. The only thing unhelpful seemed to help with was my idle usage, about 1%/hour. I still need to tinker with the kernel and try wiping my bat stats. My phone reports the battery is at 5% but when I shut it off and plug it in it's more like 30% lol
Sent from my SAMSUNG-SGH-I897 using XDA App
I had the same issue. Charge until full. Turn off and charge full... turn on and repeat. Erase battery stats via CW. The key is to let it die. Do not charge your battery until it dies....once it died I plugged it in and turned it on. If its at 1% then just let it charge completely. If its at 30% then you need to unplug and let it die again. Keep doing this until its at 1% when u plug it in. If you have to do the latter you have to start the process over again and erase stats and drain and fill the batterry. From here on out anytime you flash a rom make sure your phone is at 100%. Always let the phone die before charginging it the first time. I think the android system has to get a read of the batterry.
I think at some point along the way I charged my phone when it was at 30% after a flash so anytime after when my battery was dying I still really had 30% battery left but android was telling me my phone had no juice.. let me know if this works for you....

Battery prob is now worse!

I'm rooted first of all.
Well, wifi, all GPS, and bluetooth off.
my battery was okay, it lasted for a day mostly. and I think about 2 days ago, the battery suddenly getting worse. Everything remains same. I haven't changed any option, but the bettry is suddenly worse.
I don't use my phone that much. like I got a phone call yesterday and today? no texting, no internet, no app uses.
I charged my battery full(til 11am or til noon), then it dies before 5pm.
(Today I charged my phone til 9:40am, got only one single phone call lasted 1-2mins, and my battery is already 47%.)
It's just terrible! Anyone has same prob????
I'm in California BTW.

I'm rooted and I think it's stock rom.
I just followed the manual perm root process.
It's weird because under same conditions, battery got totally worse than before. It lasted at least for a day, but now, it lasts only 4-5 hrs with same amount of usage under same conditions.
ever figure this out?
Just rooting will not change anything to your battery life. You need to install a rom or a different kernel in order for it to change anything.
Mine too has gotten worse in the last week. I am not rooted. At this point my battery is draining roughly 25% per hour with little or no use. Spare parts shows the most usage on my phone is 0. I have tried getting rid of weather bug, Pandora and sirius. I tried looking for something to explain exactly why 0 takes up 10x more battery than Android system itself and I have came to the conclusion that I am lost. Any direction to the correct forum topic would be appreciated.

Have you tried the "Blockbuster" mod?
1) open the Blockbuster Application, it should ask you to update.
2) once the update has finished open the application back up and
3) navigate to Menu>Settings> "Disable Movie Updates"
Users have reported better battery life.
Thanks for the reply. Yes I have updated and disabled the Blockbuster app. Better yet even I just rebooted my phone and it drained 12% on the battery. How is that possible. I am using my stock battery now and not the extended, so the % would be different with the stock compared to my extended but really I don't think it should use 12% on a reboot.

All GPS was off, bluetooth off, Wifi off, everything off except 4G. I sent a text and received a text, and the battery drained to 46%. After a few mins with no use of the phone, the battery warning sound played. So I had to charge my phone at that point. It is just totally weird. Under same condition and same usage of the phone, the battery lasted for a day at least. (4G was on at the point.) I don't know what cause this problem. Anyways, I just unrooted mine and got a software update via OTA. I don't know if this will fix the problem. Any luck to you yet?
I am going to charge tonight and try current settings tomorrow and see how long battery last. It is to the point if I have to turn all this stuff off, doesn't it defeat the purpose of having a smartphone?

Try ZD Box, and use its task killer to stop any programs your not using right then. Pandora is another app that loves to stay on and chew at your battery...
My phone just started doing this as well. I've been using the TBolt for a couple of weeks now.
Just yesterday my battery life took a serious nose dive. I've adjusted all the settings I can and the battery is dropping like a drunk girl's panties...
I'm having to charge it all the time now just to keep it from giving me the low battery warning.

That's about what mine took on average to reboot. 10-12%.
I'm at 72% after 11 hours of idle usage and that's on the 2750mah extended battery. That would put me at 46% after 12 hours having not touched the phone once. I literally fell asleep as I took it off the charger...
Something is jacked up and I don't know what.
Rooted, Virus ROM B3, 1.8G kernel (forget which).
I've gone to Imoseyon's Sense lean kernel, special edition.
We'll see how that goes...?
Wanted to report back as I think the culprit may be the wireless tether app.
I turned GPS, WiFi and all my sync's back on and the phone is back to giving me decent battery life.
I did some changes with the tether app and I'll report back to see if my suspicions are correct.

This rom used to be fine, now it is draining extrememly fast and I don't know why.

I used to be able to make it through an average day of ~15 or so hours using the phone only for some messages, a call or two, and a few minutes of music. After this type of usage, the battery would be around 70-80% at the lowest usually. This is even with the screen at FULL brightness all day.
About a week ago, it started draining super fast. The same usage runs the phone down to about 20-30%, which is ridiculous. In battery stats, Android OS is always FAR above everything else with like 60%. A couple battery calibrations did nothing. I don't use task killers, but I do check my running apps. OS monitor didn't help me at all, and checking my currently running apps just showed mostly system apps that should not be draining hardly any battery at all.
Any suggestions? I think that about covers it all. This just has me stumped...
go through your apps and see how often they check for updates. there were a lot of updates recently and some settings may have changed. If nothing changed, can you do a quick scan with look out? Just to be safe. Also, try juice defender and set it to aggressive

Lookout didn't pick up anything and I set JuiceDefender to aggressive. Will JuiceDefender warn me of an app using excessive battery?
Nope, that battery is still dropping like crazy. (8% in half an hour from almost no use.)
Maybe I just need to reflash and start over fresh...
It will take a day out two to settle in. is your phone sleeping properly when the screen in off? Press the volume keys once it locks and if it makes the sound then it if still on.

Sleeping just fine.
Yea, I guess if you can't figure it out, you can reflash. That is a pain though. I would say to try out jd for a while longer and see if you get results. fb us usually the culprit for my battery drains, but if you checked all of your apps and changed them to manual, then there isn't much more you can do.try putting your screen to auto brightness

So either juice defender is helping or ADW launcher was using excesive battery. It is working better today after I switched back to launcher pro, but still going down pretty fast.
Sent from my SGH-T959V using XDA App
ADW doesn't really drain much battery for me. It actually uses less RAM compared to LauncherPro and Go Launcher (for me).
I think you should just try reflashing your ROM, maybe flashing the new GB ROMs too.
Also, are you sure you're doing the battery calibrations properly? That might also be an issue.
Maybe it's not your phone or ROM...
I've had several ROMs in the last few weeks and have noticed this behavior on many of them....after searching, I found this.
T-Mobile has apparently noticed some abnormal battery issues in areas with their "4G" HSPA+. They're asking people in their support forum for a bit of info to help them find the issue.
support[dot]t-mobile[dot]com /thread/3544
The problem was initially believed to be affecting the G2 only, but is now believed to be affecting all phones in their "4G" footprint that started when they updated their towers in late July. The update provides the government an emergency channel to use, but it appears that it may be causing network issues.
Thanks for bringing it up, this is affecting me too. i lose 20-40% battery PER HOUR of use on the phone at 25% screen brightness playing a card game online (no wifi, just on HSPA+). This is on a BRAND NEW flash of KH2 (GB 2.3.4).
The top half of the phone gets really hot and battery drains like crazy. ceasing data use cools it down and reverts to normal battery use.

[Q] Battery Life, Return Or Not?

First off, I am loving the phone. It is such a massive leap from the N1 I had been using. While I expected lower battery life, I did not expect to run through 70% of the battery in 4 hours with moderate usage.

I have heard of people getting far better battery life, and have tried the various methods, from charging to 100% then turning the phone off and charging again to 100%, using juice defender ultimate, and even resorting to factory resetting the phone. Still I can't get any kind of good life out of the battery. My question is should I try and get a full replacement for the phone or just the battery? I've only had it sinceblast Thursday, so I know AT&T will happily exchange it, but if yall think it's just the battery, I'd rather just replace that then the whole phone.

Have you found out what is using your battery?.. Even before I rooted and all the other stuff was getting at least 10hr.. now Im getting 24-28hours...
Are you running another ROM other than stock?
Didn't want to root if I needed to return anything, so I am running stock currently. Looking no app seems to be running away and draining all the battery. Everything looks the same as it did on my N1 in terms of what's draining the battery, which is what lead me to believe it's a bad battery possibly.

Well if you do root than TPC's Rom is the best. It comes with kernel and the battery life is outstanding.

I was concerned with battery life at first as well. When I first got this thing I had to plug up 9 hours after I unplugged. So now I am near 30 days with it and the battery seems to have leveled out enough for me to be happy. I got 16 hours on it STOCK no ROOT the other day without plugging in, was at 10% when I finally plugged in. Yesterday I activated Juice Defender again after getting some questions answered. I got 17 hours without a plug in and was still at 25%, so i probably could have gotten 20+ hours if I needed it.
So I am happy now 17+ hours is plenty long enough for me, I always plug in at bedtime anyway.
I'm wondering how many people who are reporting battery issues, if they have calibrated them. Charge your battery all the way, use the phone until the battery dies, then fully charge. This will give a more accurate reading as far percentage used.

There is a new ROM Piret RC1, the battery life is amazing, it has a different Kernel as the one with TPC has it';s problems.
RC1 is clean fast and in 2 hours I used up 4%. Then turned every possible service on used it up like crazy to drain the battery, installing/backing up/ flashing new rom and it took 2 hours with heavy usage to drain from 17%. Just to compare last night I had a TPC ROM and was on WhatsApp for about an Hour and battery went from 85 to 34 %.
Re: Returning the phone.
First once you root you can the same way unroot, make sure first you install a stock ROM.
My friends have the same problem, one with this phone, and others with android phones in general, don;t waist your time returnig. To be safe you also have a year to send it to Samsung to get fixed if there is something wrong with it.
Basically, running apps will kill battery, location services kills it the most, sync not so much, heavy use of data does to (I have LTE plan). Use power saver to start at 70%, configure it right, use the CPU app to manage the speed ondemand.
Most important don't frick out, the andoid phones are like that, the major difference is that Iphone does maybe 20% of what android phone does in standby and many things are not available on Iphone, so the battery is better. You will not get more then a day of use on android if you use it to your benefit. 28H is mostly standby, no sync, no internet usage, just moderate. I used to use Iphone heavy and battery would not last a day.
Get a good data plan, don;t use WI-Fi unless u have too, when syncing with the car plug it in the charger, spend extra $10 get a Samsung cable from them, don;t go for cheap 10 dollar once or even 1 dollar once from China, they are very slow to charge. My cable from the box take 1.5 H to charge to 100.
Hope it helps, please don;t quote me on anything, this is purely based on research and one week usage and trying different things, it's strictly my opinion, don;t expect your phone to last like they use too, it's 21st century and techno in it is overwhelming and needs power. Keep the phone have two cables and enjoy!
This is my first smart phone, after 20 plus years of having cel phones. I try to read before posting any questions.

good habit to get into thanks for that....the search button is your friend.
I have been reading on the battery issues, long before I posted. I have done everything from calibrating, to using juice defender ultimate, to doing a ritualistic dance to try and coax more battery life out of this phone. Still with nothing but 2 phone calls and one quick spelling look up, dead within 8 1/2 hours.
I just got my extra battery and charger from samsung in today, already fully charged up this battery and will see what it can do for a few days. I'm hoping my problems are just a random bad battery. I also factory restored and am running bare minimum on apps just to try and remove all variables. If there still is a problem I will exhange it for another one next week. I just hope they still have some white ones in stock

My battery went completely dead too. I returned mine. Black model though. New one is doing okay so far. Better since it doesn't report 100% battery until a reboot...
Finally went and exchanged it last night. So far I have gotten 9 hours of battery life and am only down to 70%. Better than before, but the vertical lines on the screen are worse on this one than the last.

I have almost the opposite "problem." Not that I'd call it a problem just yet. I had my phone running from about 10am till 1am yesterday. I went to bed and plugged the charger in and it instantly said "battery charged 100%. Remove charger." 15 hours with no drain at all? Granted, I didn't do much with it yesterday but send about 20 text messages.
Going on 32 hours+ battery life and no vertical lines.. bought it when it came out Nov6....

30% in 9 hr's? you need to see what is killing your battery... unless you play games or on the net all day.. that is not good at all..
I lose about 1% an hour..
I don't know what you smoking man but i tried his rom and never had issues. Let me tell you I Have ORD so my suggestion will be based on my usage rather than prediction. I have tried most of the themed/tweaked roms. Don't like stock rom.

Considering I used to be lucky to get 10% drain an hour on standby before, the 3% our so i'm losing an hour now is awesome. And in those 9 hours I checked google reader and played some levels of Trial Extreme 2.

Weird battery issue

For the past little while my battery has been draining very quickly. It turns out that my power button wasn't grounded and stopped working soon after the battery issues started. I got the power button replaced and ordered a new battery, but now the battery is acting even weirder and I'm not sure if it's a issue with the new battery or with my phone.
The battery will drain fairly slowly (six hours to go from 90% to 50%), but will then drop from 50% to 30% in a matter of minutes and then to 13% even quicker before the phone will shut down completely. I've tried wrong the battery stats but it doesn't seem to have helped.
I'm guessing that it's a problem with the new battery, but I was wondering if anyone had experienced any similar issues? I'm going to switch back to the old battery and see how long it lets as a test but I would like to figure this out soon. Thanks

Hi,
Maybe u can post ur battery stats to help us understand what ur using during the battery drain.
What ROM/kernel are u using?
Is the drainage during WiFi or data usage. If its data, how strong is ur signal?
There is so much that can be causing this so the more info, the better.
Oh, and is the new battery a knock-off? If so that can also be an issue.
Where did u buy it?
Thx

My battery stats from last night were mainly screen and maps. I turned off automatic updating in maps though. I can edit this post after I use my phone a bit.
I'm on stock everything but rooted.
I always leave WiFi on, but the battery has gone from 50 to 30 to dead when I wasn't connected to a network. My signal without WiFi is normally three to four bars, and WiFi is about the same.
The new battery is more than likely a knockoff. I ordered a $10 battery from eBay (my bad).
Sorry about not paying more info. I wasn't sure what else to post. Please let me know if there's anything else you need to know. Thanks

Well if you're stock(I assume you rooted but kept the same ROM) then maybe you can change kernels
or
Look for a ROM that has the stock feel but has tweaks that can save your battery life. There are a few out there.
But you'll get arguments that stock is not always the best ROM for great battery life.
Its a personal choice so look at the ROMs and pick one after you've read the thread to see similar issues/wants from it.
Good luck
If you are on Jellybean Stock then you should seriously consider using a custom ROM because Google hasn't yet released the perfect Jellybean like they released the perfect ICS in 4.0.4 update..
Secondly, you should try cyanogenmod based ROMs whichever have been great when talking about battery life (There are really awesome ROMs out there).
And follow the below mentioned steps and observe for a full 100-0% cycle drain times and get screenshots of battery stats with screentime and post here..
1. Turn the Screen Brightness to minimum; the tolerable value for you.
2. Remove any unwanted apps.
3. Keep WiFi switched off when not in use.
4. Set the multitask value by Going to Settings -> Developer options -> Background process limit -> At most 4 processes
5. Use minimum widgets and minimum home screens if possible
6. Uncheck the location services in settings. You can switch them ON when required very easily.
7. Clear Running Apps from Settings -> Apps -> RUNNING & also by long pressing Home button.
8. Clear cache at regular intervals and always use back button rather than using Home button
If above steps make a difference then it will become your style or else change the battery and get something like from OEM.

I took some of dark's advice, although I had already been doing a lot of that stuff. I'm not complaining about the battery life on the stock rom (I have already accepted that it's not the best), but rather the issue of having my battery drop from 50% to dead within 20 minutes, even without use (not at all normal for me). Does anyone know what could be causing that issue?

edit: i'm sort of wondering if my phone is reading the battery correctly. it kind of seems like six hours is a lot of uptime just to get to 50%, so the rapid drop to zero might just be because the phone isn't correctly reporting the battery's charge.
edit #2: my phone got down to ~30% battery no problem before it shut off completely. upon plugging it in to get the phone turned on, the battery had dropped to 20% and then dropped to 17% with the screen off and the phone plugged in

Your battery seems to be good enough to withstand the usage. There is one thing you can still try;
Let the battery drain completely and let the phone get switched off.
1. Now plug in the charger and on the phone go to your recovery. Here I suppose you have the latest CWM recovery.
2. Go to Advanced -> Clear Battery Stats -> Confirm by scrolling. Then reboot the phone and avoid using it before it's charged completely.
3. Now let the battery charge 100% and only after that you unplug it and don't interrupt the charge cycle.
4. Observe the changes in discharge timings. And also paste a screenshot of Screen Usage time by tapping on Settings -> Battery -> Screen (The Time on details...)

I'll try that later. I thought you were supposed to reset battery stats when your battery was completely charged so that's how I did it the first time thanks
edit: i'm just about to reset the battery stats again. my phone decided to show 40% battery as I was walking home, but then shut off and shows 0% battery now that i'm home and have access to a charger. i'll let you know what happens once the phone is fully charged. additionally, my phone will say charged while plugged in when my battery monitor thing says that it's only at ~89%, so I don't know if that has anything to do with it. thanks again
Everything seems to be going well today. I'm about 8.5 hours on battery now so I figure I'll let my phone charge a bit. Thanks again, dark. Hopefully this time it'll stick.

Every battery exhibits different discharge curves vs voltage. The os estimates battery level based on voltage. It is possible that the batteries discharge curve is just very flat throughout with a steep drop in voltage near the end which would produce the results you are experiencing. Wiping battery stats has no bearing on this issue, google cleared up what battery stats really does over a year ago. Best suggestion is to drain the battery fully, charge to 100% and repeat the process several times. This will help both the batteries discharge curve and the os's estimation based on voltage. If the problem persists, buy another battery (preferably not a knockoff) and test again. If you are still having problems after that, you may have a hardware issue with the phone. Does not seem to be a Rom issue, otherwise the drain would be happening constantly, not just after 50%.
