I have a g2x that has absolutely horrid battery life when using WXCDMA. When using it on the go, I sometimes loose like 1% life per minute or so, getting quite warm in the process. Also, when these monsterous drains occur, it continues killing the battery while sleep.
When on wifi, the life is great. I have already tried all of the various fixes, but I haven't run across anything that would stop the wcdma modem from sucking so much power.
I'm wondering if reflashing the baseband would work? Is that file even available? Input is greatly appreciated, cause I am envious of people that can make it a full day on a charge....

"Flashed multiple roms" isn't helpful. Which roms did you flash? Have you tried CM7 or one based on CM?
Have you monitored your battery usage to figure out which apps are eating up your battery?
Do you turn GPS/bluetooth/wifi off when not in use?
Replaced battery (seems to help people who have over heating issues)?
The most common causes of the battery drain/overheating is a rouge app and/or just a bad battery. My battery never even gets warm. I've noticed that even after long periods of gaming or internet surfing that the phone is relatively cool, so it seems you definitely have a problem there. Finding that problem is key.
Before you jump the gun, my SETTINGS>ABOUT PHONE>BATTERY USE:
Cell Standby = 58%
Phone idle = 42%
Display = 2%
I don't know why that equals 102% but just roll with it. A good battery monitor app will tell you which specific application is eating battery. I don't use those as I don't have a need to since I don't have a problem, but check those out and report back.

I have a brand new sim card.
Yes I have tried cm 7
I haven't tried a new battery simply because its not the battery that gets really hot, its the phone, specifically the area around the camera lens.
Also it doesn't do this while on wifi.
Sent from my LG-P999 using XDA App
I think the processor is around the camera lens. I tried flashing a rom that would simply not boot. It would go from the LG screen to a black screen and hang. That is the only time my phone has been warm around the camera lens.
So try to figure out what is taxing your processor and stop it. What rom are you running? You still haven't provided enough details. What about a battery monitor? What apps do you have installed?

Nothing was taxing the processor. This has happened on the stock rom with no added apps. Surfing the internet is what made it warm. I used an app called watchdog to see the cpu usage and nothing even went above 40%
So, I just flashed this ROM yesterday.
Full charge over night took phone off charger around 7ish this morning. Did a quick 30 minute run/walk workout w/the Cardio Trainer recording (tracking w/GPS), all while listening to the FM radio. I have had two phone calls totaling about about 7.5 minutes. Maybe 35 text messages in and out. I'm in a strong 4G area, I do not have my phone set to automatically get email. I just turned off the facebook hourly update, just noticed I hadn't done that yet ..... my phone is already barking at me that I need to plug it in.
With the exception of my run and listening to the radio this morning I really haven't done much .... I downloaded a couple of apps and tweaked them, but seriously 3.5 hours of battery before it's telling me less than 10%.
Any suggestions?
I did not clear the battery stats, in my past experiences that really didn't do anything to help (but that was w/the Eris).
I'd love to have GREAT battery life that everybody talks about. Anybody using this ROM have stupendous battery time? Not sure what has sucked the life out of this.
Thanks
I'd say it's the GPS that killed you.
same thing for me on bamf gb 2.1. i was at 20% after 5 hours of use

IDK about that, I've gone out for the same 30 minute walk/run w/the battery on yellow (on stock rooted) and the radio going and it hasn't killed it. I think maybe it's part of it, but IDK it's all of it.
I've put the phone on strict 3G, going to totally KILL it tonite and turn it off while charging.
Have you tried recalibrating your battery since installing Bamf 1.8 stripped? Maybe it's not a problem with the ROM, but with the battery calibration.
Sometime at night shutdown your phone and then hold volume down and power to boot up HTC's nice bright white bootloader. Leave it alone until it dies (the phone cannot die properly while running Android, since Android will shutdown the phone when it thinks the battery is low, rather than when the battery IS ACTUALLY low). Plug in the power cord after it dies, but leave the phone turned off. It should take a few minutes for the orange light to turn on because it's so dead. Leave it alone until the green light is showing in the morning. Then start it up. This will get the proper 0% and 100% points for your battery stats. Also check what apps are killing your battery. I was having a problem with Google Maps for a while until I cleared data on it.
I have a similar problem. I will take it off the charger and after a few minutes it will be down around 97%. No big deal. I will set it down and walk away for at most 15-20 minutes and come back and it will be on like 80%.
After that though the battery life stabilizes and I get 12+ hours with moderate use
Running AOSP CM7. I have had my phone off charge since sometime around 6 am ET this morning and at 50% now at 11 pm. This has kept me kept me from getting an extended battery. You should try it.

How is the stability on this? Is it good enough for a daily ROM? (not that it's not "good", I know their work rocks) - I don't know if I want a "testing" phase ROM. Hope that makes sense?

3g to 4g handoff is the main complaint I hear, but I'm not in 4g area. Have driven through a 4g area and it seemed fine to me. Put it this way, this has been my daily driver for over a month now. And GPS gets near instant lock btw. I don't want to hijack the thread so I will just say that I NEED my phone to work and if too many bugs were present I wouldn't be running it.

tell me your secrets
i just flashed 1.8 remix i get like 9-10hrs of battery with little to medium use
as ive said i must of lucked out with a solid battery as ive never had the horrid battery life most claim on the net. even with 4g on all the time i get well over 10-12hrs with medium/heavy usage.
a suggestion for a solid kernel is the 3.3.7 lean kernel, don't overclock too high either. i think that's why alot of people have the crap battery life and random reboots.
if you live in an area that doesn't get good 4g coverage id switch to 3g only mode if i were you.

background data and auto sync both off
moblie data off
use wifi whenever possible
switch to 3g only when youre not in a 4g area and you need to use the internet

I get incredible good battery life with the Das BAMF 1.8.6 NTE so I would expect the same out of Stripped. I would consider another kernel, I am very happy with utkanos http://forum.xda-developers.com/showthread.php?t=1025199 Are you on MR2's radio or MR2.5? 2.5 seems to do much better with GPS.

What is using up your battery because if it is the Cell Standby or Phone idle I have a fix for you. I had always had great battery life until last week when it started draining as you describe in your post. I tried everything to get back to where I was but was not successful. I ended up pulling out the 4G card and reinserting it. I was instructed to do this by a Verizon tech. I though he was wasting my time but it fixed my battery issue and I am getting great battery life on BAMF 2.1 and also BAMF 1.86

That's interesting, I wonder what that would do and why it would work? These phones do like to keep us on our toes, eh?
I've made the switch to CM as of yesterday so I'll be playing around w/that for a while.
Hell,
After 13 hours on battery, "Android OS" is top battery consumer on my Gingerbread device. I understand there is some kind of bug in Gingerbread causing this behavior, but I already pulled battery out and put back in before. Am I supposed to do it every reboot, or how do I fix this annoyance?

Which Gingerbread variant? There are unfortunately multiple causes for this and it can be a ***** to debug. I had it happen for a few days with CM7, but I think it may have been a side effect of the Bluetooth fix breaking GPS, making anything layered over GPS unhappy.
Apparently for some people it's caused by a corrupt SD card that causes mediascanner to go nuts, and on the Nexus S it was caused by people setting Wifi Sleep Policy to "screen turned off" - yes, setting it to "never" would actually save you battery. But at least on CM7, setting wifi sleep policy to "screen turned off" is OK.
It's Infused V2 2.0.3 version

Try setting "WiFi sleep policy" to "Never" and then turn off wifi.
Yes - it seems weird but according to some of the Nexus S reports, even with wifi off the sleep policy mattered.
NOTE: This may do absolutely nothing. As I said, there are multiple things that could cause this. But there have been a lot of reports of wifi causing battery drain on Infused v2.
My WiFi sleep policy is already "Never" but WiFi is on the whole night. Since it's both saves data and battery according to reports.
I have this problem occasionally and it is always fixed (until it comes back :/) by a simple reboot. I'm pretty sure it's the same problem detailed here that GS2 users had and was eventually fixed by some unknown code change from Samsung.
Basically we just need to hope that when ATT releases GB for Infuse it will have the fix in it.
my problem on infused v2.0.4 is that my cell standby eats up most of my battery... about 35% when i got out of school. is there any way to fix this?
It's fixed in 2.3.4.

I understand where your coming from, but from any cell phone standpoint 13 hours off the charger and 50% battery left is great! You are on track to Running that battery for over 24 hours, and I don't care what phone you have that's impressive. I have run 2.0 - 2.0.4 and the difference from stock is amazing going From only making it 15 hours and needing to charge now I can make it over a day easy.

Sometimes various sensors like rotation too contribute to the time android system takes up.
ok so here's the deal.. my phone has been off the charger for about 4 hours and im already down to 40% left. I live in a 4g area but it is spotty in many areas, including my workplace. I have gps (for weather updates and nav, when i need it) and wifi on at all times. i am running the EP4P modems on GummyCharged Froyo ROM 2.0. I have the screen brightness turned all the way down.

I have tried several different methods to calibrate the battery but it doesnt seem to help. When i'm at home and using wifi the battery life is pretty good. so is it my modem? the ROM? my kernel? Can anyone help me get the most out of my phone? I've tried various modems but have stuck with GC since I loaded it back in sept.
If you are in a spotty area, that can happen. Searching for signal and 4G/3G switching can drain the battery very fast. I would try putting the phone in cdma mode while you are at work or any other spotty area.
Turn off wifi and gps if you are not currently using them, wifi scans for networks regularly and you may have apps/widgets that are using the gps/ network location services while you are idle
also, my battery stats say that display is using up 45% (as of now) of my battery life with 23 mins of usage time. I have the wifi turned on for my convenience, but it doesn't scan for networks as i've turned that function off. I will try the cdma switch, but I have also tried that before and I don't think it makes too much of a difference.

The battery usage metrics aren't useful until you've been up for several hours. And having the screen using a high percentage is ideal -- it means that the rest of the system is throttling like it is supposed to.
How long have you been on GummyCharged? A few weeks into having that on my phone happily, battery life took a nose dive similar to what you are experiencing. I flashed back to stock and battery life is much better. Waiting for official GB before trying another ROM.

i see your point but im now at 5 hours uptime with 23% battery left.. light/medium usage. display still says 46% battery use with 25 mins of usage time. that seems like incredibly too much battery drainage.
also, when i put the phone into cdma mode do i select the home or automatic option, and what is the difference?

i flashed GC onto my phone in mid september. since then i've tried calibrating the battery several times. a totally futile exercise it seems. What setup are you running now? 2.2.1 with EE4 modem? Rooted?
The only thing that has solved my battery problems is juice defender. Sitting idle for eight plus hours at night I only drop about 3-5%. Of choose it still drains just as quickly while using the phone but it will help if you're in a spotty area because data is turned off if your screen is off.

I have similar issues. After rooting and flashing Humble on my phone, my battery life sucked, much much worse than stock.
I then put the standard 2.3.6 on it and it still sucks. Full 4G all day, barely use it.
It's sat on my desk at work all day today. Sent a few texts. I've installed betterybatterystats and nothing is taking up a large portion of partial wakelocks.
Really don't understand how people are getting such good numbers...
I find that by far and away the best way to increase battery life is to lock my phone in 3G unless I am downloading something & want the 4G speed.
I have a home screen widget that turns 4G on/off & only turn on 4G occasionally. I do not leave WiFi on although I leave GPS on at all times & find that uses almost no battery life whatever.

I thought my battery was bad then i looked at that graph. I don't even get it... The screen is mostly off and the signal is green most of the time.
It may be some rogue app on your phone. Backup your apps and do a factory reset. If your battery life significantly improves, restore your apps one by one and find the culprit.

Just stock EE4, unrooted, will do OTA as soon as I get the notification. Battery life is not that good, I can get 14 or so hours of use leaving it on 3G most of the time, but on Gummy I would get 50+% drain just having it sit overnight. Now leaving it sit overnight doesn't kill it.

you prob shouldnt be using that ROM..its kinda outdated...just flash the new ALL IN ONE ODIN of EP4D...my battery life is pretty sick...i left it unplugged all night and saw a tiny drop..my phone was connected via wifi tho..if my phone is in 4g the battery loses pretty quickly or if my screen is on ultra bright..
I'm running the stock, rooted, manually-debloated EP4P and I've been getting downright stellar battery life.
My kids watched an hour of Netflix this morning while getting ready, and now (almost 10 hours later), I'm still at 63%.
But! (and here's the kicker) - I leave WiFi on all the time (I'm contemplating buying Woofi to save even more battery when I'm not at home or work) and have my WiFi sleep policy set to "Never".
This is (one of) the key(s). It doesn't matter how strong your 3G or 4G signal is, WiFi will always save you battery. 3G is less battery intensive per-time, but much more battery intensive per-byte. 4G is less battery intensive per-byte, but much more battery intensive per-time. WiFi is much more battery intensive per-time, but wildly less battery intensive per-byte.
In other words, for the same download, you'll use the least battery on WiFi (even with a slower than LTE connection), 4g in the middle, and 3G the most.

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.
