Ok, so I made a Genius appt and went to the Apple Store yesterday. They looked at the phones usage and immediately knew what my problem is, and the steps to take to rectify it. If your usage and standby numbers are basically tracking the same (they don't have to be identical but generally the same, then you have a problem where your phone is not going to sleep when the screen is off. There are two ways to address this, one in Software the other is that you have a bad piece of hardware that the software uses to sense sleep mode. To address the software part of the problem, you need to go into DFU mode and completely reinstall iOS6. From there, setup your phone as new and then start re-adding apps manually. DO NOT RESTORE FROM BACKUP. You have something in your backup that is screwing up your sensing of sleep mode. You will lose all of your previous text messages etc. Sucks. If your contacts are all backed up in iCloud, you will get those back. If this procedure does not fix your problem, as it did not fix mine, then you have problem #2. There's a hardware line that the software uses to sense when the phones in sleep mode. You will need to get a new phone. So, after going through process number 1 in the apple store with the genius, we waited 10-15 minutes to see hoe my battery life was, without running or installing any apps. In that time, my battery life dropped 5%, with the phone being restored from DFU mode and not a single app installed form iTunes, just the stock apps that come with the phone.
Another clue is how fast your phone charges when you're connected to your computer. I had my old phone connected for 2.5 hours yesterday after I got down to 2%. In that 2.5 hours, the phone only charged to 31%. It could barely keep up. My new phone came out of the box with 60% charge. After I went to the gym, and got home, I was still at 49%.....But I had used Pandora for the hour that I worked out. From there, I plugged in ans started the process of getting my apps, music and videos back on. That took approximately an hour. In that hour, the phone had fully recharged back to 100%. So, where 2.5 hours only went up 29%, I was able to get the battery up 51% in an hour.
The genius that I worked with was very knowledgeable, and helped me out quite a bit. I'm a hardware/software engineer, so troubleshooting what was going on is right down my alley and something I love to do.
As of right now, with my new phone, I'm at 91% battery with with 50 minutes of usage and 3 hours and 22 minutes of standby. This is significantly better then what I was experiencing with the other phone.
