And I'm still not satisfied with the battery. I know battery issue is a pan to deal with here and I'm truly sorry. I did a soft/hard reset, fully drained the battery about 4 times now, turned off all the things i don't use, but yet, it still drop about 5% per hour with barely/light usage. I mostly text 25-50 messages per hour (could this be the problem? that would be odd) and it would drop about 10%. This is my third Lumia 920 and I really don't feel like going through another process of getting another one. Any suggestions? Thanks!

5% per hour....I'm sorry but that is just funny....people need to get over their battery %...If you make it through a whole day then your good and lucky most would say.
There is nothing wrong with the battery on all these Lumia 920's, sure some might have it worse then others but there is not magical update that is going to make everyone's battery last 2 full days without charging it.

To be fair, 5% consumption while idling is indeed too high. I can think of two reasons:
1) Your phone is still too new. You need to use it for longer than just 4 cycles for the battery to really settle down (at least that applies for me, it used to use quite a lot, but now I can easy go 2 days idle, with occasional messaging or calling, bluetooth always on, 3g)
2) Your cellular reception is poor. Your phone keeps on looking for stronger signals. That occurs at my work place, my phone just gets somewhat warm usually when I am at work. During off days, my phone battery just lasts very long.

Let me just say, that 25-50 messages per hour is a lot and it is completely understandable, that you may be loosing 5-10% juice.
it all may depend for example on your screen brightness, if it is medium/high, then completely understandable.
When you write a message, the screen is all the time on and touch screen sensors use up a little bit of juice as well, especially if for example you have high sensitivity turned on.
Having said that, my Lumia 920 after Portico update and hard reset uses 6-7% over night with wifi turned on, 2-4% over night with wifi turned off (no 3g data enabled).

I think most battery problems are app related. I restored my replacement phone and only made one change (installed a battery meter app) which had a profound effect on battery life.
After a few days I started thinking that I might have been sent a duff one. Battery usage BTW was 5%-6% an hour with 3 background tasks, 3 push email accounts, WiFi always on and moderate/heavy use so hardly terrible but not the stellar performance of before.
After uninstalling the specific app everything went back to normal if not better. I now end the day with 65%-70% with the same usage patterns.
I have all the "smart" features enabled except NFC, this needs to be looked at by MS/Nokia, it seems to be a problem as far as battery use is concerned.
Also, when using the phone for navigation I use a car charger, the battery won't last long when GPS is in use but this is to be expected.
It is not a coincidence that all dedicated Sat-Navs are designed to be always plugged in, GPS has a massive power drain.

WXGA (1280 × 768) resolution with an aspect ratio of 15:9 using enhanced IPS screen technology which Nokia calls "PureMotion HD+". It has less than 9 ms average transition times, where conventional IPS LCDs have an average of 23 ms, which reduces motion blur. The screen's backlight luminance reserve, together with a new automatic adaptive system for adjusting brightness, color and contrast details to compensate for lighting". this has a huge affect on battery consumption. this IPS display is basically supercharged with a refresh rate of 60hz. this is why it looks so damn good and moves so fluid. so if you text then put your phone down and leave the screen on letting it turn off on its own, you are further draining your battery because your screen is not in use waiting for the screen timeout to kick in. and depending on howq long you have the timeout set to this can increase battery drain also. the screen is always going to be the biggest battery drain on a smartphone. it's true on my galaxy s3 when looking at the battery manager and it's true on my lumia 920. so constantly turning off your screen 50 times to text and leaving it on after you text while waiting for the screen timeout to kick in does indeed drain your battery 5-10% per hour. this also happens on my galaxy s3 with the amoled display. plus screen brightness also comes into factor. when you take all of this into account, 5-10% battery drain for that many text messages in an hour isnt really that bad. i might do 50 text messages in a day, an hour boggles my mind. hahaha.
