Is it definitely an official CyanogenMod? Rather than one someone's modified further?
Seems odd from my experience of it across multiple handsets.
X-13... maybe an issue specifically with the Galaxy S version of the ROM?
You should almost always get your stock samsung firmwares from Firmwares | SamMobile
Even the carrier branded firmwares are available.
I didn't realise Samsung published them - that's handy!
edit: oh they don't :P from the link I assumed it was an official Samsung site!
As you probably saw on my other post I too have been having issues with cyanogenmod on my S3 and battery was one of the issues. However the constant freezing and crashing being the major one.
Not saying it is because of CM, because I have had many versions which run fine just that it COULD be ... (as reverting back to the stock rom has fixed the freezing and given me better battery life)
I don't get it. I've put this on two Samsung Galaxy S3 devices and no problems what so ever if anything the devices performed a lot better. I heard that in the UK apparently the only unbranded phone was if you buy them from Three. Me & my girlfriend are on Three, great network but they don't brand the phones either. Though I have heard company's like EE and O2 like to install different apps and have sometimes been know to change small things in the hardware for security and all sorts. So maybe it's because you have bought a phone from anyone but Three?? Just a thought....
@alexbillbridgnorth i've had it on this i9300 international unbranded completely unlocked for over 8 months with no issues at all. Just the most recent cm-10.1.3-RC2 and 10.2-M1 releases
I couldn't get the stock rom to boot properly, it was just looping.
I've installed the latest version on CM... >25% battery gone in 30 minutes.
First full day of use on the latest Samsung FW & ROM and I finished the day with 47% battery!! NEVER seen that from any CM ROM. Weird
