Whenever I leave my phone charged overnight, I wake up to around 70% charged. It's as though once it reaches 100%, it stops "charging" and it starts using the battery's energy, rather than the AC. Any help?

What kernel/rom are you running. The only suspect is that your kernel does not have "trickle charge" in the new kgb kernel you have to enable this with the app.

Is there any Custom ROM in particular that you would recommend?
go here http://forum.xda-developers.com/showthread.php?t=1238070 and follow step 2, then go to http://forum.xda-developers.com/showthread.php?t=1459905 readthrough the first part on TW kernels, choose one of the 3 custom kernels (not the stock one), best advice is to read the op of each one and find one you think will work for you. they are all three well written kernels. one is already oc'd to 1200, which means no need for voltage control if you plan to oc your phone. most phones are stable at 1200 but thats just from doing alot of messing around and odining. the second post is the instructions for flashing the kernel. the first post just explains all of them to the best i could w/o kanging any information from the op. i just ran what i knew off memory. links to each kernel's op are at the bottom of post 1. i did links to the op's instead of posting dropbox files due to the fact that I want people to make sure they know what features each kernel has before they download it.

They are essentially the same thing. Battery Calibration is wiping the battery stats and running the phone dead than fully recharging.
I have been having a very similar issue. A buddy of mine (captivate) and I found that the phone wont charge past 98% on CyanogenMod with the Glitch kernel. I set the phone to not lock and keep the screen on while charging and the problem went away. The phone also would not stay on A/C power after reaching 98%. This issue was fixed too.
I think its an inherent problem with the batteries on the phones, since the issue occurs on many different roms/kernels/phones.
whether it's caused by the phone, ROM, or kennel, battery calibrator is a simple app that is at least worth a try in my opinion

Thats because your phone is mis-reading your battery's charges.
a Re-condition would help phone re-read it more accurately, but idk how you'd do that since to re condition you have to charge till' 100% lol.

the CM7 your using is not OFFICIAL, so the problems your facing is up to the developer to solve, not the CM team because as far as i know, they haven't even supported CM7 for us fully yet.
it's just how cm7 is reading the battery. on one revision i would get a max of 95% then 97% on another. just recondition the battery after its been plugged in for while after hitting the 97%. worst case is you have to recondition your batter again after you flash another rom or it gets fixed.
Do you know what cm7 version they've used as a base for the vibrant version? The Nexus S does this by default, to protect the battery as others have mentioned.

YOU need to re-condition, YOU can fix it.
the people on MIUI or CM7 can't.
As stated its a known thing.
I used my Samsung Focus to charge a battery to 100 percent put it in my phone and it discharged to 95% then back up 97%. So the phone isnt charging the phone up all the way as it is. This is also good for the life of the battery and the battery will last longer. Also it gives and accurate reading. Sometimes with phones if it says 100 percent it is discharging thus you actually only have <95%.
I fixed the problem I just switched to best rom(trigger) then reconditioned and it charges perfect thanks for the help

This is by design and should occur on all Roms. Below is a link to a good Phandroid article tiled "Your Smartphone's Battery Gauge is Lying to You and its not Such a Bad Thing". It really does an excellent job with a fair amount of data explaining why your battery will only charge to 95 - 97%.
It boils down to three options:
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge

I told you before everytime you flash a different rom, the battery is going to be different, so reconditioning is going to help you make it more accurate reading. brah.

You may need to do it a few times.
But since you are on a 2.2.1 rom... no need to worry, when it tells you its at 97% it's actually at 100, soon when you don't notice going from 1% to 2% will take more than regular time, it'll make up for the 3% somewhere along the lines

I get better battery life with KB5 too.
I can confirm that data use is probably part of the issue. I live in the sticks, there is no 3G at my house. My battery life is actually descent, no where near what I had with Froyo, but it doesn't seem to be anywhere near as bad as other people are claiming.
turn off background data when you don't need it, don't use auto brightness.

Yes, also doing that. I recommend to go to the Android Market and search for Battery Calibration by NeMa. It's a great, free application as well to make sure that your battery is calibrated on top of the instruction from the quote.
Using spare parts app change wifi sleep policy to never. Known bug in gingerbread. New wifi drivers were just released for stock builds but I don't know if theyll work on cm7 or if they will be implemented.

Ya battery calibration app works quite well, that is something I haven't done yet with this ROM 0_o
I was having terrible, absolutely terrible battery life with CM7 and I decided to do some investigating. On my initial installation I used Titanium backup and Google Backup to restore settings and applications. I could not manage 4-6 hours on a single charge, with calibration.
I decided to do a fresh CM7 install to test things out. I simply booted into recovery and wiped data, cache, and system. I reinstalled the initial package provided on the CM forums and let CM7 boot. After letting the new installation settle down for 10 minutes, I rebooted into recovery, flashed gapps, and then the newest nightly. Again, I let it boot and sit for 10 minutes before performing anything. After settling down, I charged up to 100%, rebooted into recovery again, and wiped battery stats.
I should note that through this I declined google's offer to use backup services and declines google's offer to restore any old backups. I also decided to not restore any apps through titanium backup.
With my screen brightness set to 100%, wifi enabled, bluetooth enabled, and using the phone at amoderate to heavy amount, I have gone 12 hours and am at 5%. I am certain that after the battery stats can calibrate fully and run through a few more charges I will easily hit 15 hours on moderate to heavy usage.

if you have rom manager pro the nightlies are available for download.
here's a few tips for you guys:
1. turn off 3G, stick to GSM only. Found in settings > wifi and network > mobile network> gsm only
2. use some black themes, anything than the normal grey and stuff should help
3. If you have data, use that instead of wifi, from what I see wifi eats more battery
4. if you're using wifi, go into wifi settings > *menu button* > advanced wifi settings > wifi sleep policy to: when screen turns off or never when plugged in.
hope that helps

Ok so these last couple of days I've been having the strangest problem with my vibrant. The battery litterally sucks it self on the charger. For example, today at 3 in the morning I woke up to find my phone charging at 71% I was like ok good. Woke up at 7 and the phone was completly dead! It looses power on the charger. At first i thought it was the battery so i switched it. And whattya know. Still the same problem. Then i thought it was the usb port since ya know samsungs port sucks ass so j get a new charger and nothing. Let me remind you tthat this is a recent problem. Any body know a fix to this?

Have you tried to backup and re-flash your phone? Have you tried a battery calibration by wiping the battery stats? My advice *having never encountered that issue* would be to save all your data, make a list of the apps you use regularly and re-flash the phone then manually re-download each app and do not restore anything. if all goes well and it charges like normal then your set and can if you wish restore your old data and/or apps 1 per day till you notice the problem, return if it does.
I did just that. Reflashed a new rom and less drain but its definatly.

If the phone gets hotter than 120° then it wil stop charging and actually dicharge. Make sure your not overcloking or ajything.
My advice on which rom if your not set would be to use trigger. I moved to trigger a long time ago after one of my bionix flashes didnt work quite right and have not looked back yet. I am currently on project v with trigger theme which is a little more like stock but with tweaks than a fully custom rom.
Ok so I got it to charge too 100% overnight and I unplugged it and it went down too 37% instantly. -__- just started working today and this isn't cool. I also left it by a fan so it wasn't hot at all.

In that case I would be sure to flash back to stock clean and then go to a different rom, I suggest Trigger 3.2 very stable in my experience, and charge to 100% and do a battery calibration. Trigger comes with an app to calibrate the battery and be sure its fully charged.

WIping battery stats is useful when installing a new ROM, so it can measure battery capacity better (extreme tl;dr version). Install BetterBatteryStats and look for unusual wakelocks and processes. Report back with what causes the issue and we will see. If you could include screenshots of BBS, that would be the best
You don't get it do you? It is wiped when you install a ROM. It is WIPED when you charge to 100%. The batterystats.bin has no effect what so ever on your wake locks, battery problems, or anything else you think it is related to. All it does is report to the settings what has been using the battery.

You know there are nicer ways to tell someone that wiping battery stats doesn't do anything . If it doesn't do anything than it shouldn't be in the options...period. I was trying to be helpful and offer a suggestion..and it couldn't hurt to try.
.. so whats your suggestion so no more "lies" get spread??
CWM is largely generic, so the Battery Wipe option is there whatever device. It is a waste of Dev. time to remove/customise for every device.
It doesn't do anything... in this case. It may on other devices.
But this is largely OT now... so back in the room.
It doesnt do anything for any device. A long time ago it was thought to do something. But a Google Engineer said otherwise pubically.

Calibrating your battery (or calibrating the software to correctly read your battery's charge) was something that needed to be done on the captivate (SGS1) after installing a new ROM but not on any of the galaxy phones since then. Even then the software would correct itself after a charge or two.
