I never had to do all the stuff you're talking about with any other phone I've had.
That may be, but if you wish to improve your battery life on this phone, some effort will be necessary on your part. If you're not willing to entertain suggestions or methods that have helped many owners on this forum, I don't know what to suggest other than take it back to VZW and exchange it for a different phone.
I just want the battery to make it through a day of light to medium use. That is currently not happening...not even close.
It should be able to handle that -- unless your signal strength is so poor that it's eating your battery away, or there's a defect somewhere. I cannot stress enough the importance of optimizing the phone for your use, which includes disabling/uninstalling apps you don't want and never use, and turning services on/off when needed. Make sure software/accounts you never use aren't going wild trying to sync.
Mine was just off the charger for 30h+ with 4 hours of SoT and 35% remaining; as mentioned above I've regularly seen 5h+ in a 24h cycle (
example). On my "light" cycles I've seen the better part of two days on a charge.
