I put cm7 nightly on my g2x and noticed that the battery readings are not accurate. They don't seem to update at regular intervals , thus giving inaccurate battery life. Anyone else notice this?

CM7 is no where near complete yet. You'd be better off posting things like this in the development section.

Cyanogen has reported that the battery drivers are not fixed in CM7 nighty. So the battery info is still pretty much worthless (just as it is now).
I need help my battery life is terrible and I don't know how to fix. I have a battery information app and the battery chart drops.

We're going to need more information than that to help you out.
ROM?
Kernel?
Name of "Battery Monitoring" App?
Current Data use?
Signal strength in your area?
All of these will be very helpful in figuring out what your issue is.
Try to be patient, I'm a little new. But here's what I know.
Froyo 2.2
Kernel 2.6.32.9
Battery Monitor Widget App
Data usage isn't high.
I don't know how to find ROM
My display takes 93% but my brightness is all the way down and my signal is always pretty strong.

Im guessing your one the stock at&t froyo. Think about going into the captivate android development section and flash a custom rom. They seem to provide better battery life and are much better than what came with this phone.

You can also disable wifi, bluetooth, and GPS when not in use - that should help.
In my experience the fastest way to better battery life is flash a new kernel. speedmod-kernel-i897-k13e is very stable. Also turn off auto-rotate and auto brightness.
A big battery killer for me is background data and auto sync, I leave it all off, along with the stuff every one else said.
Also, try calibrating your battery.
The only thing I've done to my phone is root. And I've turned off all the auto stuff, I have no idea how to "flash the rom" or anything else.

If your display takes up 93% of battery that's usually a good sign, it means that there's probably nothing in the background sucking up all the juice. Have you tried "bump charging" or replacing the battery? They do tend to go bad or lose calibration if you've overheated them one too many times.
Whenever I charge my phone it seems to get extremely hot. The battery app said like 115° to 120°

Try Juice Defender in the Android Market, made a big different for me.
In my experience Froyo roms have all been garbage battery life *first leak, stock, Perception, Cognition, SuperNova, Phoenix Unleashed* I could never get more then 10 hours on the battery and less with wifi on. Now with GB *perception 2 beta 3*, I get 18 hours with Bluetooth on, Background Sync On, under H *3G*, and the original battery that came with the phone. I am putting up with some of the issues that 2.3.3 has but to me I cannot go back to froyo as my battery life has never been this good Including with jf6 2.1 that originally shipped with my phone.
HTH,

I put it on the charger. Only went up to 35c (95f)

While that may be the case, it doesn't always provide for the best signal. You have to test each one and see what works best for your area/situation.
Your battery temp seems very high. You may want to swap the battery before trying other things. Is the phone new? If so, At&t store should agree to swap it out for you.

This is probably one of the worst phones on battery life that I have ever had... No matter what I do, what tweaks I use of what rom I'm on... I always only get 7 to 8 hours of battery with 1 hr screen on time.
I honestly have no idea what to do... I'm so sick of it. Anybody have any suggestions?
Seriously?
I have been on my phone all day with a full charge and I still have about half the juice. I am on stock 4.0.4 ICS. The one that droidstyles has in his guide. The Rom that came with my phone sucked on battery. This Rom works great for some reason.

What are your settings on? Post your settings (like screen, whether GPS is on, ect), a lot of times it has to do with your settings. I used to have so-so battery life but I tweaked some stuff in my settings and am very pleased with the phone.
Believe me, if you want bad, try the Droid Charge. Worst 4g phone I have ever had in terms of battery life.
This is on clean rom. Ignore the screen percentage, going down since this was a recently flashed rom.

I'm on pure motives rls7
I'll add a screen shot of my battery status tomorrow cause I just plugged in
I get 30 hours with 5 and a half hours screen time.
Idk why your battery life is so bad.
I have power save on, no vibration, and sync set to manual. That's about it. Battery life for me is amazing.

Possible Idea
Don't know if this problem could occur with different ROM's, but I had issues with a runaway process that kept showing up. Maybe try Developer Options -> Show CPU Usage. I noticed that one called gsiff_daemon kept showing up at the top and was making my battery drain extremely fast. Everyone on this forum said it was a common issue and that it wasn't a crucial file, therefore I should just change the name so it wouldn't get accessed.
On RLS7 and kt kernel? This kernel has capabilities for overclocking/underclocking & overvolting/undervolting. By default your min Mhz is set to 384. Go into ktweaker and lower it to 96, test your phone out with a scaled stress test (play store app for stress testing). Then you can also go into the extra settings of ktweaker and set the Mhz for when your screen is off in addition to the governor (many options of which some are powersaving labelled).
If you want to save more battery read the kernel's thread to see starting undervolting values and lower from there while testing your phones limits. More undervolted you are, the less battery your phone uses for that particular frequency.

You obviously never had the thunderbolt, now that battery sucked. You have to let the rom settle in and your battery will improve. Usually for me the first day not so good after that everything is fine.

I had a Thunderbolt. Yep, now that was poor battery life.
My S3 gives me 12 hours if I use it heavily. Typically, at 16 hours, I still have 40% remaining. I leave WiFi, bluetooth, and GPS on 100% of the time.
As bad as your battery is, I would suspect that you have a poor radio signal.and the radios are cranking up the power to work. Try using WiFi or turning off mobile data for a while to get the LTE radio turned off.
man, i barely get 8 hours at times

This. For example, I have a 4g tower nearby at work, normally (4-5 bars). But sometimes it disappears, and I end up on a 1-2 bar 3g tower for the day. On those days, my battery life is around 8hrs max, barely using it. On good signal, even with crazy heavy usage (4hrs screen on and lots of 4g web browsing) I can get over 8 hours.
Signal strength has a LOT to do with battery life.

Check your Google account sync - could be something in there is not syncing correctly. Settings / Accounts / Google.
I had this - Internet Sync was not working but kept trying burning CPU, network, and battery. Disabled the failing sync and all was better.

I am using stock battery on stock jellybean leak and get 30+ hours with 5.5 to 7 hours screen on time you can see from the pics above that we are not charging. The bar would go UP at some point if we were.
I just have my phone set up the perfect way to get maximum battery life.

Hello, ever since flashing cm 10.2 on my phone, I've noticed that my battery was being drained extensively by Google services. A full wipe and re-flash later, it was fixed. Well, during those two flashes, my battery level has been erotic.
I can go 4 hours with normal drainage and then the phone casually reboots, and then says I have 9% or so remaining. It will "charge" itself to 13%, reboot again, and it the battery will report that it has around 20% or so, and drain normally.
The battery life has diminished a bit, but that could be because of age, and it barely lasts me 8 hours.
Does anyone know of any solution other than buying a new battery? Recalibrated has helped, but not by much.
As always, any and all help is appreciated.
Thanks,

in around a few crashes and drain wipe, the battery report can be way off
after a few cycles, it should normalize
if your drain persists, look to wifi drain, cpu regulators, wakelocks or rogue apps updates causing drains
Thanks, right now I have better battery stats to analyze wakelocks and apps and then I have greenify and system tuner to freeze Google services and apps. Hopefully this minimizes drain.

I need a way to debug my phone and figure out what is causing such high CPU usage and poor battery life. After startup, my phone sticks at 100% until it freezes and restarts but sometimes I get lucky and it goes down a few percentages but freezes again when I start multi tasking a bit. I don't know what changed. Any app to debug or log what's going on?
Also my phone will read a low battery amount and when I restart, it jumps up 20-30 points

I've been using various apps (android system info, better battery stats, battery stats plus, watchdog) and I'm getting nothing. Nothing is hogging my cpu at all...
Sent from my HTC Sensation 4G using xda app-developers app
Install Wake Lock Detector to find out which process is hogging your CPU time.
From what I can tell, all the normal startup apps (mesages,facebook,widgets), are using full amount of CPU. All of them. The blue bars were full. That's for the few minutes after startup being 100% usage. Still investigating the random spikes that occurs while using my phone. It's a matter of being able to open and use this app as my phone becomes unresponsive

So I've been running apps and periodically monitoring my CPU. When it starts to get above 80% on both 0 and 1, I check what's up with wakelock detector and it doesn't even list the app I'm using when my cpu spikes like dolphin. It happens often with dolphin, tumblr, games. But they don't appear in wakelock.
The apps that do appear are barely doing anything

What's your battery ?
4 hours is very low. Maybe you need new battery..
And which rom exactly do you use ?
I used Inspiration 1.0.1 for a log time and i had the best battery life on this rom. it works fine with lower CPU/GPU frequency. Vipers 5.0.0 also seems to have nice battery life (i'm on it now).
