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
Edit - Updated with more recent stats

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
neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
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.

How long does 1 of those batteries last?
Sent from my HTC Glacier using XDA App
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.

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.
I've had my nexus s (9020a) since late November (bought it used, in execellent condition.) While battery life was never awesome, it was at least bearable - until last week. I'm now unable to get more than 6 hours on a battery with super-minimal usage. For instance, today, as of right now, I have 5h 58m 57s (at 7% battery left) - the top "user" being the display (32%) with a "time on" of 17m 30s. Even when I power the phone completely off (not the screen, literally powering off) - say for a half hour or so - when I power it back on I lose substantial amount of battery.
Some other details:
Currently running stock 2.3.6 rom (since yesterday), but rooted.
Previously was running stock ICS (flashed the tmobile 2.3.6 ota, then ics, then the att radio) - was fine for the last 2 months
Tried brand new battery (not a samsung, but Anker) - no difference
Tried several different charges, and charging via computer
Have wiped battery stats several times (and done complete resets/formats of everything in between swapping roms)
Phone used to always top out at 95% when charging - but now will go up to 100%
This behavior started up when I was on vacation - a few hours after landing in SLC, UT. I do recall a sudden crash / reboot of the phone before the problems started - but I have gotten random reboots in the past. Was running ICS at the time. I thought maybe a poor signal was to blame, but again, the battery would drain even when the phone was powered off (or in airplane mode.)
I'm not sure what else I can/should do - short of calling Samsung. I'd think if it were a hardware issue, it would fail to charge completely. Does anyone have any other ideas or suggestions?
Thanks in advance!
Sounds like something external is draining the battery. I've seen many cases with a magnet on them drain the battery very quickly, or possibly excessive heat. If not i would say it's some kind of hardware problem.
Does not sound like android chewing it up.

I don't have a case on it - just a screen protector. The battery does tend to run in the mid 90s fahrenheit (according to battery status apps.. though I think I have seen it as high as the low 100s (maybe 102?) - but I figured that was normal.
Another weird behavior I should mention: sometimes when I power off and on while charging, it will cause the battery percentage to jump considerably. Right now, two consecutive on-off-on cycles (within the span of 3 minutes) caused the battery percentage to jump from 36% to 44% to 57%.
Heats normal. Not sure what it could be to be honest. Maybe grab a can of compressed air and spray around the back, maybe dust causing a short or something.

Thanks, will try that
Sent it back to Samsung for "repair". As I suspected, all they incompetently did was re-flash 2.3.4 and say "passed all functional testing". Phone is still hosed and completely useless as-is.
(Fully charged, overnight - less than 8 hours - went down to 17%, with no apps running, no google accounts, no sync, no background anything, no screen time, no wifi, in airplane mode)
Samsung really is hopeless. Going to try again with them? Whatever you decide, best of luck. Hope it works out for you.
what is the mv reading when the phone is fully charged? Fully charged should be around 4200mv

Trying again, but not optimistic. I talked to about 4 total "customer support" people today.. at least got them to "upgrade" me to 2-day shipping for sending back and forth instead of the normal ups ground.
It is so foreign to me - coming from Apple where, under warranty, they'll pretty much swap problematic devices out for new ones _in store_ on a dime. I pretty much begged Samsung to just send me a refurb unit to replace it with but they said thats "not their policy."

I don't have it with me (send it back for round number two) but I am fairly certain that is around what it was reading.
The thing would even burn through battery when powered off, if the battery was still left in. Taking the battery out = no drop. It has to be something hardware.
Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.
on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?

btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha
Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search
Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues
fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms
I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.
Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.

I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.
I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.
I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(
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.
Ive had my htc one x for maybe 5-6 months which is almost the longest ive ever been on one phone and i love(d) it, but its always been doing something very strange and aggravating that seems to be getting worse. Battery drain has always been a problem for me with this phone but ehh i can deal with it, but once my phone gets down to about 14% which is does often because of the draining it starts acting real funny with its power and sometimes goes from 14 down to 5 in an instant literally out of no where and as soon as i plug up itll go right back to 13, or itll shut down entirely at 14% but i can just cut it back on, or itll shut down in the middle of me doing something and i have to charge it for about 5-10 minutes before itll even come back on. The latter happened last night btw. No matter what combination of roms/kernels i try this always seems to be a problem. I really cant deal with this anymore and its to the point where i wanna throw my phone into a wall and just buy another one, which im seriously thinking about doing at this point. If such thing has happened to anyone before or you have insight on this can you please help before i just give up hope completely.
What you have described is normal for our device. Remember that the battery percentage is just an estimate of your actual charge. In addition, you find your phone shutting off around the lower percentages as a result of the device attempting to prevent damage to the battery. That is what the HOXl was designed to do.

Last night when it did it, as it has before, i was still on 21%.... thats not normal. And this isnt my first android nor first htc, never happened before. Even on my aunts old one s it didnt happen
Do you allow full charges after these "forced shutdowns" occur? This should cause your battery to recalibrate.

The battery behavior on this phone has been interesting. I have the battery last over two weeks on airplane mode and I've had the battery last just a couple of hours with just a stock setup. There are so many factors that play into this. I work in an area with very little to no signal reception and my battery life goes crazy and the phone can get really hot while I'm there so I've seen the best and worst.
What I do to counteract this bad behavior:
1. Charge prior to 40% (I've had the phone go from 40% to zero instantly before)
2. Consider your signal reception and either try out different radios or use airplane mode to reduce erratic battery drain
3. Install a 3rd party app like batterycalibration (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en) and use that when things get hairy (I calibrate every two weeks or so and that does the trick for me.
My phone has been like this since I pulled it out of the box. With a little management, it is just fine. You have seen it before but I'll say it again, you have to get through a few charge cycles when flashing a new Rom to get back to normal.
Hope this helps. It works for me and I work in a cell phone reception hell.

When a new ROM or kernel is flashed you need to let battery settle for at least 48hrs before you get super worried about battery. If possible during that time let device fully discharge then charge up to 100. Please use a battery monitoring app and then see what's causing the issues. With proper config hoxl will get good battery life. There is always the chance its hardware issue but doubtful as battery prolly would of completely failed by now. Also check your screen brightness settings. Hope this helps

Ive done all three methods youve mentioned before and still same thing. Also im on 3/4 bars with lte 90% of the time so no reception issues here. And with my current setup ive been running it for about 2 weeks.

Ive always let the rom settle in and i constantly maintain the brightness on around mid level (mirror screen protector so i cant go too low) but its not just one rom or a few, its with every rom i flash ad that consists of most roms available for this device
The battery behaviour you described is completely normal if you understand how a battery of this type works, and if you understand how the software (especially the display of battery percentage) works in conjunction with it.

So youre telling me having the phone get to 22% and instantly drop to zero and power down is normal? Makes no sense at all. Also i cant get it to charge too 100% for anything. So if theres no fix to this, anybody want a one x with a troublesome battery?
What I'm saying is the battery percentage displayed by the software is never exact, it's only an estimate based on the voltage level of your battery. Your battery sounds like its long term life (capacity) has been decreased over time and possibly bad treatment (allowing the device to discharge too much too many times).

Depends on what you define as "normal". Such behavior is certainly not unheard of (although you particular collection of symptoms may point to a more serious issue, which I'll get to later). Couple things you have to remember: the battery meter is far from accurate. Being off by 10% or more is not unusual (completely normal). So jumping from 5 to 13% as you mentioned is not out of the question. The battery voltage is not actually jumping around, just the % battery number that the phone is assigning to various voltage readings. Reading errors happen, and if a jump is noticed, its just the meter correcting itself.
Which brings us to the other point that should be kept in mind: the battery % is not a "real" measurement. Its just a number assigned to various voltages to give the average person a sense of how much battery is left. Its a completely fabricated and artificial measure that just gives some relative sense of when a user should charge their battery. Phone makers just decided to use a system that average people would understand, like the fuel gauge on a car. Zero doesn't really mean zero (or anywhere close), but reporting in voltages would make no sense for most folks. Also, as we all well know, just because (for example) it took you 12 hours to drain the phone to 50%, does not necessarily mean the phone will last another 12 hours to drain the remaining 50%. It all depends on what you are doing with the phone during that time. Which leaves the question: What does the % battery really mean? Really, not a heck of a lot.
On the other hand, the battery failing to charge to 100% is troublesome, as is the apparent frequency of the meter drops and the fact that the issue remains after various ROM flashes. Leads me to believe there may be some hardware issue going on.
The short answer: IMO while some of the individual symptoms are not unusual, the seeming frequency (you haven't exactly quantified this, but it seems relative frequent just based on your descriptions) may suggest a larger issue, but its not certain.
Thanks it explained a lot but it happened again today, went to the store with ~36% on the meter and walked out, haven't touched it at all, phone was completely dead. Tried to charge and it went to 6% and stopped charging, all signs showed it was charging but it was stuck on 6. Then it started climbing again and reached about 16% and actually started losing charge while on the charger. Switched over to my portable battery charger i just got and it held the charge at about 5% for ~30 minutes, which is what it was when i plugged it in and started to charge, then it stopped againand during the whole process the phone was getting very hot. Yea im getting a new phone :/
