Cellular performance on 4G LTE is actually quite good with the Charge. Samsung’s CMC220 seems to be a top-notch performer among the LTE basebands we’ve seen thus far on Verizon’s LTE network. I performed all my testing in the Phoenix, AZ and surrounding area market, and the Los Angeles, CA market. I ran 361 tests on the Charge connected to Verizon 4G LTE, and like we’ve done before have them reported below in histogram form.
It’s really nice to see a very distinct normal distribution emerging on the downstream throughput tests, with a standard deviation about 5.5 Mbps centered around 13.0 Mbps. I saw a maximum downstream speed of 36.8 Mbps to speedtest.net’s LA server, and an average of 15.2 Mbps. Upstream throughput is likewise starting to show something of a distribution centered around 5, but the distribution is flatter here. Keep in mind that we have a lot more data here for the Charge than we did the Thunderbolt, and honestly it looks like the two would have developed similar distributions with much more testing.
I also did something out of the ordinary and thought it might make an interesting thing to report alongside these results. I made a few artists available offline on the Charge in Google Music, and recorded a video of monitored throughput in System Panel, which is an Android monitoring app and task killer.
Things are a bit less interesting when it comes to EVDO performance. I’m getting used to seeing a sort of flat distribution of downstream tests ranging between 0.2 Mbps and just shy of 2 Mbps on EVDO Rev.A. On upstream the Charge shows a clustering results between 0.6 and 1.1 Mbps which actually seems a tad faster than the Thunderbolt’s. The Charge in this respect looks like it doesn’t suffer any ill consequences despite having a non Qualcomm CDMA baseband.
The Charge only reports signal from both the CMC220 LTE baseband and the VIA Telecom 7.1 in steps of 10 dBm. As a result, measuring the phone’s in-hand attenuation was a bit challenging, and ultimately not too exciting. The Charge simply isn’t prone to errant deathgrip again thanks to mandatory Rx diversity.
The Charge doesn’t use the same antennas to do double duty across either baseband - each gets its own set, and each does its own Rx diversity. There’s a clearly visible strip on the back of the Charge that runs alongside the right of the battery compartment which does WiFi and BT duties. The FCC supplies a nice diagram of how this all works out - Band 13 is for LTE on the CMC220, and bands 2/5 are of course for the VIA 7.5 to do CDMA/EVDO.

I'm happy to see that the NEXUS line particularly the NEXUS S can hang with the latest and greatest, while running a non-skinned OS and a single core chip. That formula seems to be the winner IMO. I only wish that future phones from any manufacturer would began life like the new Samsung Galaxy Tab, no skin from the factory, but add-on skins available via the market or the individual manufactures web store. This would enable Goog to keep the latest OS on more handsets from beginning and give end users even more options without having to root or hack the phone risking BSOD or worse voiding the factory warranty. Having said that, NEXUS 3G will certainly be a beast if NEXUS S is the ground floor! Thanks for another superb analysis ANANDTECH!!Nexus S 4G stock

Hi Brian,Thanks again for the great article. I've had an OG Droid since it came out November 2009 and lately, I've been looking for a phone to go to. I want to get into the unlimited plan which I've had since I bought that device and don't want to loose the privilege, even though I don't use 3G that often. I was seriously thinking of getting the Charge because of some of the reviews I had read on other sites, but was eagerly waiting on your recommendation. I now come to the conclusion that buying this phone is not in my best interest. I would love some 4G love, but the fact that battery life is outrageously in comparison to the LG and HTC LTE phones, I will have to see what the Bionic will bring. Like you stated in the previous article about the LG, battery life will likely not increased until the LTE radio is embedded in the phone CPU, which Qualcomm is working on right now. I guess I will try to grandfather my plan and see if Verizon will let me replace my phone when the Galaxy II S comes to the states.
Thanks again for the great article. I love Anantech for the indepth coverage you guys provide to all products. Informed consumers is what we need.

all existing unlimited data plan customers are grandfathered in until ... further notice. I have this info from a leaked verizon document but ... sorry too lazy to find link right now. July 7 is the deadline to get grandfathered in, as I recall.Belard - Saturday, June 25, 2011 - link
Overall, the new data plans are a rip-off and hurt the abilities of these new phones.$25 for 10GB a month should be the min. One one company will drop to 2G when you hit the limit (rather than send you a $2000~4000 bill).
But when the caps are so low at 2~5GB, whats the point of having a 4G high performance internet phone when you can make out your data plan in 1-3 weeks?
They are promoting video and music downloads, streaming - that'll kill you. And google maps / GPS... that'll eat data as well.

It really shouldn't be this hard.- Thin doesn't always mean better. Strike a balance.
- Light-weight, if its feather-weight or poorly made, it may break easily.
- SIZE, sure its nice that phones come in various sizes... but as they get bigger, they become harder to get out of our POCKETS.
I have a Samsung Galaxy S Captivate (at&t)... the screen is great, the metal back looks nice.
But its design is flawed like all Galaxy S phones.
A) - Power button on the side, hard to feel (only on Captive)
B) - speaker on back = BAD BAD, I prop my phone a bit to hear the weak alarm.
C) - TOP and BOTTOM look exactly the same... HELLO? The Charge is better because YOU know instantly which side is up.
D) - my previous SONY phone, which I used for 2+ years still looks as new as my Captive (6 months old)... the whole bottom isn't flat and is not cheap plastic.
E) - REAL BUTTONS!! I like the charge already. Having a REAL HOME button is nice. Its location is STUPID as its the most use button on the phone but its NOT on the edge, nope... its in the middle? Should be: HOME / BACK / Menu / Search (Search can go away thou)
F - if using physical buttons, make the search a SHUTTER button when phone is in camera mode.
The Android interface FROYO fixed most of the GPS issues, but is somewhat DUMBER than 2.1.
- They removed NON-REPEAT function from the Alarm? STUPID!
- The Alarm profiles move around!! WTF?!
Heres a REALLY STUPID ONE...
The PHONE LOGS are defaulted to ALL, including MESSAGING?! The 2.1 had ALL or Phone Only... in 2.2 Froyo, they added some more, but TOOK OFF PHONE ONLY?! What idiot did this? Who the hell wants to SEE their TEXTING LOGS with their PHONE LOGS?! So I have to use SHOW only MISSED or SHOW ONLY incoming, etc... not just ALL phones. Again, STUPID.
Home button issues... Using an Ipad has shown how a HOME button is supposed to work. With my Android phone with its hard to find power button, I'm constantly turning the phone ON again, even in a phone call so I can see the screen. A Physical home button should always bring back the screen (if blank) rather than the power button. I hate getting a TEXT notification, and I could be in the middle of a swipe to unlock the phone to go to the text, and the PHONE shuts off.... gotta press the power, do the swipe all over again.
I like the flexibility I get from Android - but the User Experience is still crap . Having a WindowsPhone7 style launcher makes the phone much more usable.

The article says that the phone has 512 MB RAM and 2 GB internal storage. However, my phone's task manger displays only 328 MB RAM and about 1.17 GB internal storage. Are there different versions of the phone?nitink - Monday, August 1, 2011 - link
