Not really good. I think you have installed some apps which are sucking juice from your phone. Look at mine below.

Check your Gmail, Sync and other settings like email, weather app etc. If you leave it to check every 1 hour or so then it sucks up battery like mad. For me, all mail sync are manual and I only allow Sync to sync my Google contacts list. As for Playstore, I set to sync on WiFi only.

That's exactly what it is doing. All apps has a timeout duration and retry time. So with your data line switched off, it is actually doing more checking that with the data line on as it will keep on retrying a few times. Imagine it doing this every hour, definitely your battery will run flat in no time.

U win some and lose some lar. I am using without JD and gets about 1.5-2 days on the S3 depending on usage. U just need to disable all those non essential widgets and make sure you sync settings are set to manual except for those crucial ones. As for email, I set it to manual, don't really need push mail features.

Try activate photo uploading using Dropbox from your device. I think that is what got me the extra storage last time.

Key into Excel, import to your Google account and let is sync to your phone lar bro.

Send your phone to SC to check bro. I think it is the phone problem more than the SIM card.

Okay, I am going to root my phone tonight and flash CheckROM too. Wish me luck.

Going to flash OmegaROM later. Any comments from users here before I do so?

Yup. That is the latest for now.

Officially on OmegaROM. Now to check out it's new features and see if it can give me better battery performance. Anyone here can point me to a list of bloatware that it installs without?

Restoring stock ROM. Don't like the fact that the wallpaper has a dark band on it. Looks damn fugly.

Anyone knows how to fix the wallpaper issue in OmegaROM? Would love to use it but the scrolling wallpaper creates a dark band at the 1st and last home screen.
