IPhone 5s (new) has terrible reception, 5 PICS included. -115 db reading!?!

Question

I just got an iPhone 5s. FIRST THING I noticed when I was getting ready to walk out the Verizon store - my iPhone 5s was reading "3 bars of 3G service"  inside the Verzon store. What!? Every other device in the store has bull 5 FULL bars of LTE service (I know stores have their own boosters inside) but even with the booster I was getting only 3 bars 3G service inside the store!! I went back inside and asked the lady at the counter, she said it was "normal for the phone to have bad reception and switch between LTE and 3G during first day".... I didn't really believe her, but I said okay and left figuring I'd wait 24 hours to test it. As I figured, that wasn't true. The iPhone 5s has been having both poor reception and worse speeds on the same Wifi compared to both the iPhone and iPhone 4s, side by side.
Right now, In my home I CONSTANTLY locked onto one 1 single bar of LTE service. The coverage map shows I am in a full LTE area, and my street is a full LTE area. So it's not that. If I turn "LTE OFF" the bars increase to 3 to 4 bars. This means that the LTE signal is weak at my home. But I'm NOT turning LTE off, why would I want an iPhone 5s if I wanted to use 3G service?? The iPhone 5s is suppose to have better LTE reception and more bands....BUT: THE LAST PICTURE SHOWS THE iPhone 5s in 3G mode vs the iPhone 4s in 3G mode, and yet again the iPhone 5s has worse reception..
I've tried to: turn off LTE, turn it back on. RESTART network settings. HARD reset phone over 4 times.. I've done an icloud back up over 3 times. Nothing has improved it. After looking at the pics, is this NORMAL for the iPhone 5s to have these problems? Should I exchange it in back for the regular iPhone 5?? I still have time left to exchange it. I don't think a NEW iPhone 5s will fix the problem, as I've read online the 5s has MANY reception issues...Although I suppose I could try an exchange one time, but the iPhone 5s still has problems after the exchange will they still let me switch back to the iPhone 5? (It's only been 3 days, so still 12 days remaining). I would ask a customer service rep, but they aren't very honest so I will not take their word for it.
HERE ARE THE PICS showing MULTIPLE PROBLEMS from Signal problems to Wifi problems to Ping problems, etc...:
PIC #1: (BELOW) Showing Verizon iPhone 5s with LTE on VS Verizon iPhone 4s (a non LTE phone). This pic is just showing the reception/BARS only.
iPhone 5s ON THE LEFT with the iPhone 4s on the right. The 5s only has 1 bar. The iPhone 4s has many bars. But bars aren't everything, so here's them in field test mode:
PIC #2 (BELOW)
The Verizon 5s on left has a -115 DB reading (that's HORRIBLE) vs the Verizon 4s that has a -80 DB reading (good)
PIC #3 (BELOW): This is showing that even on the SAME Wifi, in the same spot, the 5s is pulling SLOWER speeds, pretty big difference. I've ran this test 20+ tests, same results every time the iPhone 5s loses sometimes by 1mbps othertimes by 5+ mbps, again on the same Wifi in same spot.
Pic #4 (BELOW) :Here is the test where the 5s came VERY CLOSE to the 4s in terms of download Speed, but LOOK AT THE PING, HUGE PING DIFFERENCE. Again SAME Wifi in SAME spot.
Notice the 5s has a ping of 45? While the 4s has a ping of 18? Big difference. Also the 5s had 1.88 upload, while the 4s had 3.13 upload.....
Pic #5: I just thought I'd compare the Verizon 5s to a Verizon LG flip-phone... Even the flip-phone gets better service!!!
This is just pathetic... The iPhone is suppose to have TWO great Atennea, and the improved technology over the years is suppose to have BETTER reception.. Nope, not on mine. The flip phone constantly gets 4+ bars of service, somtimes full.
LAST PICTURE: (3G VS 3G in field test mode)
Pic 6:
The 5s on the left has a -94 DB reading, while the iPhone 4s has a -84 DB reading. THEY ARE BOTH ON 3G MODE, side by side. Yet still, even if I turn on iPhone 5s to 3G only it still has worse quality.... I've tested everything I can think of, and the iPhone 5s is doing worse in everything!!

Answer 1

BTW, I have done 25 speed tests witin the last 2 hours ALL IN DIFFERENT LOCATIONS. Verizon LTE network is averaging about 6mbps download speed, where in the store they where doing 40mbps++. That's a huge difference. In some areas when I got 5 full bars of LTE, I did a speed-test assuming I'd be blazing fast. Results? 1st result: 10.23mbps with 5 full bars of LTE..... Another test with 5 full bars of LTE got me 6.52mbps. That's bad, with FULL bars of LTE and near a tower, and using an iPhone 5s getting 6mbps download on FULL bars of LTE??? What?? My AT&T iPhone 5 always got at least 20mbps MINIMUM with 5 bars of LTE, it never got 6.52 mbps download speed with a full 5 bars of LTE like my Verizon iPhone 5s is doing... I'm pretty disappoined. I just ported over from AT&T a couple days ago only to find the service is much worse. I hope this is only a bad phone, and not the actual Verizon network. Otherewise I will have to cancel my service and get a refund (I still am within my 14 days return policy for a refund).
And yes, I have tried taking the case off with no noticable improvements, maybe I'd get 7mbps with no case while I'd get 6mbps with a case on. So a little difference, but still only 1 bar of service in my home, and on my street. Not acceptable.
I have tried ALL of the following, nothing has worked:
#1: Reset all network settings (5 times+ tried)
#2: I've contacted Verizon TECH support and they have manually reset my network settings. Did nothing. Infact, I did TWO speed tests before calling and I was getting around 12mbps in the location I was at. Although I checked and I was within 0.5 miles of 3 different Verizon towers, so that explains the decent speed for the first time.
THEN after he reset my phone and I powered it off for 5 minutes, I did THREE speed tests: 1st result was 2mbps download, and twice the ping as BEFORE the reset. 2nd result was around 4mbps. And the 3rd result was around 3-5 mbps range. So after the manual resest it got WORSE in the same spot I was standing. Either way, even when I got "decent" speeds it's still pretty darn slow for LTE in a major city... 
#3: Hard reset (5+ times tried)
#4: Turning LTE on and Off. This helps the bars, but again I don't want no slow 3G that gives me 0.5mbps download speed, that's useless.
#5: TOOK OFF THE CASE, and tried. The reception did not increase, but, when running speed tests, I would get about 1mbps faster with the case OFF rather than on. Still, this is not enough. Plus the reception remains at 1 bar in my house, even holding it near the window upstairs. I live in a full LTE area and checked the street coverage, it says I am in a full LTE area....... So not even taking the case off helped reception, it only helped a little bit for speed tests (but 1mbps different on a few tests may not be enough to be certain). So even with NO case, it's doing poorly...
I switched to Verizon because I thought they had better coverage than AT&T, I actually cancelled my AT&T iPhone 5 and ported it over JUST to get Verizon....I live in Colorado Springs. Now I'm finding out either A.) My phone from the store is defecetive or B). The Verizon network is pretty awful in my city, even though the map shows full LTE coverage,and full LTE coverage in all the surrounding cities too! So I am in a HEAVY LTE coverage area, and town.
