Now let me understand this battery issue !

Question

Most everyone is complaining about poor battery life ,,, correct ?
My HTC TP2 could go strong w/12hrs b4 needing a charge, Iphone would last 10hrs. with heavy use until a charge needed.
Verizon/Htc put up commercials that had a lightening/heavy electric cables etc. THAT should of clued us in that we would be required to use something other than the battery to last a full day !!  They sold (promised) us a phone under the pretense of 4G lte speeds, but probably 25%-35% do not get that speed,, oh well, but didn't expect such a POOR battery in otherwise a fine phone, sure you can get the FAT battery but WHO 1 expected to have to spend $50 more just to last all day on moderate use?
So as I understand their tech. support, the answer is to..GIVE UP your 4G (that you basically paid for) also turn OFF a lot of your apps. (that you use w/android), you end up paying $250 for a standard $99 smartphone. It's like buying a Corvette only to have a 4 cylinder motor in it because there is not enough room for the V8 !  I live in the dark red map area for 4G coverage only I only get it 25% of the time so I'm locked in by my choice to the 3G, If things on Verizon's side don't get much better soon I will turn my beloved (sometimes) Thunderbolt in & get the Iphone. I realize that this IS NEW TECHNOLOGY but "V" has let it's customers down by ether NOT field testing TB or they just had too much invested & too late to back out ? We as consumers will never know.
We will be locked in to our contract soon, with little or no chance to improve our cell service & products,, so we are STUCK !!
The ball is now in Verizon's court so lets see how this game will be played out, They know there is a big problem, so lets see how it is handled.

Answer 1

I've had my tbolt for almost 2 wks. Until today I have been getting 24 hrs on a charge and actually use the phone (phone calls while on 4g internet, playing with the mobile hot spot <mhs is a battery hog>). Yesterday I downloaded qik and played with bitbop (pretty cool tv app) and maybe a few other apps.
This morning the phone was dead. I completely charged the battery and took the phone to church @ 8:40a. By 11:30a the charge level was down to 15%.
I charged the battery again after church (again making sure the it was fully charged) removed the phone from the charger @ 3:45p. By 8:30p, the remaining charge was < 15% and I hadn't used the phone (left it on my desk while doing other stuff). Must be some runaway process draining the battery? 
BTW: I live in Vegas and have been really happy with the 4g speed. A friend has an evo and we were in a restaurant in Henderson. We d/l a speed test app and each ran the test. His speed was less than 1 Mb (we verified his phn was in 4g mode), mine was greater than 10. I have been running the test all over Vegas (inside the 215 loop entirely so far... that may make some sense to locals) and the lowest speed I have posted is greater than 9Mb. For me the speeds have been on the high end of the 5-12Mb range VZW promises.
