Help Noticeable battery drainage

I've been noticing my phone battery having big drains for no reason at times. I'm using the Seidio 1750 mah battery. I've had great performance with Seidio on my HTC so I'm wondering if there is something wrong with the phone itself or some type of settings or updates I need to make?

Looking at my battery graph its a steady slope downwards, at times it smooths out and then a big drop.

Any ideas what is wrong?

Btw, I am using Juice Defender and have all the obvious things OFF such as GPS. Screen brightness is at <15%.

This battery used to go for 2 or more days.

Thanks
 
Have you recently updated to 2.3.6? There is a lot of chatter about that update significantly affecting battery life.
 
I just checked and I am using 2.3.6.

Android OS is using 89% of battery, is that normal.

Btw my phone is rooted with good custom rom, forgot all the specifics but I did it earlier this year.

go to menu>settings>about phone and let me know what version you are running.
 
No, 86% is really too much if you are using the phone regularly. You can see hi OS usage if you've not used it for a while, but I'd suspect other issues. Keeping WiFi on was an issue with the stock 2.3.6 but I don't know about the custom rom. Do you remember which one you are using?
 
btw, i dont use this phone much at all

im going to turn off WiFi and see what happens. I was thinking WiFi would have saved battery instead of using.

are there any updates/downloads I can do that would fix this battery drain?
 
there are different roms for each phone. I dont have an HTC so i can't suggest any. But even if I did have your phone, I would tell you the same thing: Try different roms. Phones can respond different to each rom, so whatever works for me may not work for you.

For the i777 (AT&T SGS2) I'd say ShoStock2 and AOKP ICS are both pretty good. I'm currently using ShoStock as my daily and it's been incredibly stable and excellent on battery.

You can get the rom's here: AT&T Galaxy S2 ROMs | Galaxy S2 Root

Sorry, you mentioned HTC in your first post so I assumed thats the phone you have.

If you have the i777, I'm running SHOstock and its really smooth with great battery life.
