Verizon vs AT&T iPhone 4

The differences and the polish of migrating to Verizon iPhone 4 would be nothing if the user experience of the Verizon iPhone 4 is underwhelmed, but happily the iPhone4 experience on the Verizon CDMA network is very impressive. In the week people have been testing the phone, from the initial user reviews, it seems none have experienced a single dropped call, and voice quality has been amazing both on the caller and the receiver.

CDMA network has no fluctuation in data transfer and offers solid data throughput speeds. Anyone who has experienced what Verizon’s LTE network will know it. AT&T’s iPhone 4 GSM experience lacks Verizon’s consistency. AT&T version has much fluctuations, high and low peaks of data performance, depending on your location, whereas my multiple speed tests reports from people in different locations have shown that the Verizon CDMA EVDO Rev.A is much more stable. Verizon’s 4G network is still a work-in-progress, and most “would-be “Verizon iPhone 4 users are not in in the 4G zones. Below is a coverage map of Verizon 3G and At&T 3G networks taken from EVDOinfo.com or you can use Verizon’s Coverage Locator to see if you are covered.

AT&T vs Verizon iPhone Data Speed

The AT&T GSM Network can handle voice and data simultaneously, whereas the CDMA has to switch over as it cannot handle voice and data simultaneously. When switching over between voice and data, the Verizon iPhone 4 quickly picks up the 3G data connection once the voice call is completed. Individual user experiences may vary, but surely, the voice data switchover will not damage the user experience. This may be a hindrance when you use the mobile as a hotspot and share it with 3 -4 users, where a sudden voice call can momentarily block the data connection you are sharing with laptops or tablets. Reconnection is instant and automatic, but lets say, you are in the process using of uploading a file, it will stop and you have to re-upload which can be frustrating. Somebody may come up with an app or some sort of automatic call rejection option in the settings to prioritize Voice/Data.

Here are some other key differences you should know when you switch from a GSM to a CDMA network. If you are wondering what may be practical differences to an user switching between from an AT&T iPhone to a Verizon iPhone, the comparison chart below from Apple may answer many of your questions. You can see how the regular call features like call forwarding differ between these networks, but also what’s possible and what not possible with iPhone on a CDMA Verizon network vs GSM AT&T network. Some features just are not available on one network or the other and these are network limitations, not the iPhone itself.

The Verizon iPhone 4 has the same battery life as the AT&T’s GSM model. It can handle up to 7 hrs in voice calls, up to 300 hrs standby, 6 hrs of browsing over cell network or 10hrs of wlan browsing. There are some tricks like turning off push email and improve battery life. If you are like many users struck with the iOS 4.3 battery draining issue, this fix may help as it has helped lot.. There are plenty of additional third party battery packs for the iPhone, but it’s worth checking to ensure they will suit the Verizon iPhone 4′s ringer switch which is slightly offset from the standard one as you can see below.
