Massive battery drain - Galaxy Ace S5830 General

Hello folks,
This is my first post in the Ace forums, had a Wildfire S earlier (which I still think was a better phone )
Ok, so I got my Ace two days back. First thing I did was root it, installed CWM 5 and then installed a custom rom. My battery drained in 2hrs!!! I thought it must be a rom issue so I flashed another ROM and still having my battery drain pretty quickly. It goes from 65 to 41 if I just reboot it, it's that's BAD!
This wasn't the case with the stock ROM I used for about 5 hours. Some help will truly be appreciated

What use did you make to drain it in 2 hours? Heavy games?

Nope, nothing. As a matter of fact, I didn't even have any game installed. It was on standby all the time.

Thanks for the replies guys.
Is Link2SD a known issue in this regard (?) cos I realize the moment I downloaded and linked apps, the battery is starting to drain real quick!

---

I'm using a2sd on ics final flashed over ks9 baseband. In addition i'm using slaidfastmod and framework mod (you will find it in development section). Lately ice cream Sunday Rom has been pulled by developer, so ATM is not available. Cyanogenmod RC0 should be fine as well, as it is its base (search for it in the forum).

This was on medium usage, with about 2-3 hrs of 3g internet browsing, Facebook, SMS, calls, Bluetooth and screen brightness pretty high.

3G is an Ace killer. Make it easier to turn on/off, so the battery lasts longer

---

Using wifi saves more battery then using 3g. I've noticed it on my ace. My battery approx. Lasts me 1-2days. Using apps like juice defender helps battery last longer.

You can also try battery calibration (available on the market)
This helps a bit I think.

I dont think calibration helps with battery...
but juice defender really helps.
all you have to do anyway are,
1.reduce brightness to lowest.
2.Switch to 2g when you don't use data
3.switch off data, gps
4.disable sync and background data.
you can enable those when you want to use.

---

Battery calibration deletes your battery stats giving you more accurate battery statuses after you have switched roms.Switch off GPS and mobile data when not in use.Theres not much to do about this

Nope I don't think link2sd causes that kind of a problem.. I'm using link2sd in infinity rom and with music playing for more than 3 hours and with heavy wifi and 3g usage I used for around 8 hours.. And it's pretty good.. Also I have overclocked upto 902MHz on performance governor.. Try some tweaks and calibrate the battery properly..

I think Overclocking drains battery very quickly. Overclocking makes CPU & GPU very hot. And as you all know, loss of energy due to heat.

Thanks a lot for all the suggestions. Calibrating and moving to a stock ROM did help. Now the battery's quite normal on even the CM ROM's.
Thanks a lot guys (and girls? )
