My battery on my new S3 seems to be being eaten up by the cell standby using more than 50%. I appear to get a decent signal on the phone. Does anyone have any idea why this figure would be so high?

That is terrible! Drains to 50% only in stanby!
Maybe the apps are not really shut off. You can use the free apps - JuiceDefender to save your power. Packed with smart functions, it automatically and transparently manages the most battery draining components, like 3G/4G connectivity and WiFi.
Or you may need to have a external battery to backup. This one sugegsted:
Small and portable design, Powerful and giant inside. Will be helpful!

XDA recogined contributer bala_gamer has explained and fixed this issue. Check this xda-developers thread and this news item.
It would seem that the issue comes from an error in framework-res.apk. XDA Recognized Contributor bala_gamer explains that the power drain value setting for Cell standby is erroneouslyset to 34 mA (practically impossible) instead of a more reasonable value of 3.4 mA in power_profile.xml within framework-res.apk. He then put together a corrected power_profile.xml, and provided a quick step-by-step guide to pushing the change. Those not excited about messing directly with framework-res.apk can thank Senior Member ausdim for providing a recovery-flashable update.zip.
Don't forget to read the warning and FAQ if any.
