Cellular & WiFi Performance
The Epic 4G is the second smartphone we’ve reviewed that has a WiMAX radio for use on Sprint’s 4G network. This is actually why I’m reviewing the phone and not Brian, Raleigh, NC happens to be one of the 40 US cities with Sprint WiMAX coverage.
Those of you who read my EVO 4G review will remember that I did’t have the best experience with WiMAX in Raleigh back then. I’m sorry to say that the situation hasn’t really improved much since.
The best download speeds I’ve seen are still in the low 3Mbps range, and upload is usually stuck around 1Mbps while on 4G. On a good day, AT&T’s 3G network is anywhere from 1 - 2Mbps down and 1 - 1.5Mbps up in my area. As with the EVO 4G, Sprint charges a mandatory $10 per month Premium Data fee for 4G support regardless of whether or not you use it.
The other issue is consistency. I usually don’t get those 3/1 numbers, often times I’ll see speeds more like 1/1 or 1/0.5Mbps. I’m always seeing screenshots of users in other WiMAX areas with speeds 2 - 3x my best case in Raleigh, so this may just be a problem with coverage in Raleigh. Either way I’d suggest looking into what to expect in your area before making a decision based on 4G alone.
Speedtest Results for the Epic 4G, all results on 4G except for the topmost result
I will say that I no longer have the problem where 4G performance is worse than Sprint’s 3G in my area. I usually get around 0.5/0.5Mbps on 3G, so there’s a noticeable performance increase when WiMAX is enabled.
And just as was the case with the EVO 4G, 4G isn’t actually more of a battery drain as long as you’re stationary. If you have it enabled while you’re moving around (rather than just turning it on once you’ve gotten to a location) you’ll see a drop in battery life.
Whether or not Sprint itself is a good network for you depends entirely on coverage in your area. In my experience, AT&T is usually either great or absolutely horrible - there’s very little in between. While Sprint (and Verizon) are consistently good. Compared to areas with great AT&T coverage, Sprint can’t compete in performance - but where AT&T’s coverage is weak, Sprint’s average performance is usually better. Awesome occasionally or consistently reliable - those are the two choices it seems.
WiFi performance was better than the Motorola Droid X and the Nexus One, but behind the iPhone 4.
Like all other smartphones we’ve reviewed, the Epic 4G’s cellular signal does attenuate based on how you hold the phone. Given the sheer thickness of the device it’s harder to get the large signal drops by holding the phone that we see on thinner devices.
| Signal Attenuation Comparison in dB - Lower is Better | |||||||
| Cupping Tightly | Holding Naturally | On an Open Palm | |||||
| Samsung Epic 4G | 10.0 | 5.0 | 0.0 | ||||
| Droid X | 15.0 | 5.1 | 4.5 | ||||
| iPhone 4 | 24.6 | 19.8 | 9.2 | ||||
| iPhone 3GS | 14.3 | 1.9 | 0.2 | ||||
| HTC Nexus One | 17.7 | 10.7 | 6.7 | ||||
The biggest drop I noticed was 5 dB when I held the phone normally, and 10 dB when I held it tightly trying to cover as much of the antenna as possible with my hands. This is in line with other Android smartphones (actually a bit better), and obviously better than the iPhone 4.

It's an interesting review since it starts out with some good words and ends with, what my impression is - well it's a POS.And I'm sorry Samsung, but a phone needs to last more than 5 minutes and a GPS needs to work. We really could not care about it looking like a damn iPhone. Hell, people buy iPhones for that.
Try harder Sammy.

There seems to be an agreement amongst high-end Android users that battery life is terrible within the first two weeks, but then significantly improves after the battery has been conditioned. It's possible that due to the short review period, this never get's a chance to happen, causing an under report of the battery life.It would be fascinating if you did a follow up later on to determine if this is true.

The functional battery life is pretty long. I can pull 1.5-2 days if my use is limited (maybe 20 minutes of calling, 20 or so text messages, little to no browsing). The Hummingbird really does sip power when it's idle.If you're hammering away at it for 4 straight hours, then the battery life is pretty poor.

But other than emergency situations, are you really going to have a phone like this and only use it that little? I've mentioned before, I wish they could come up with some type of "real-life" battery test that would include a certain amount of talk, text, web, video, etc. per hour. For example, I would be surprised if the battery in my HTC Diamond lasts much more than 2 hrs in 3G browsing, but in my usual day (5-10 min talk, 80-100 text, few MMS, 10-15 min web, many times turned on to check the time) it generally has 20-30% still showing when I put it back on the charger after 15-16 hrs.Dane74 - Monday, September 6, 2010 - link
On battery break in: with Lithium based batteries, break in is negligible. The observed better second week battery life comes from playing with less features.I expected better battery life than my spouse's Evo, due to more efficient power usage of the Epic's processor as well as its screen. We found the battery life to be equal, my impression from behavior of both in weak signal areas is that Epic's voice, 3g and its 4G reception is slightly worse than Evo which will cause some additional drain on power.

My personal experience (6+ device batteries so far, including phones, cameras) shows a 1,8-2x battery life improvement after 3-4 charge-discharge cycles. And it's definitely not due to unbalanced usage. The same holds true for both Lithium-Ion and Lithium-Polymer batteries, although the more I think about it, the more I convince myself that Lithium-Polymer are more susceptible to break in.Ratman6161 - Tuesday, September 7, 2010 - link
I've got an original Droid now running Android 2.2. A while back I picked up a couple of spare batteries cheap online. These are identical to the one that came in the phone. When I swapped in one of the new batteries it was showing up as fully charged already. I started rotating the three batteries every Friday to keep approximately equal usage on each one.I never really noticed any difference. Then again I wasn't specifically looking for that and did not do any kind of test.

I have the Samsung Captivate (not the Epic 4G), but it's still in the galaxy S line. I noticed that I needed at least 3 complete charge/discharge cycles before I got reasonable battery life out of the phone. It wasn't a decrease in usage either, I made sure I kept my usage patterns consistent.My experience with the Captivate now is that I can listen to podcasts all day, read all my work email, do some web browsing, and still have around 60% battery left at 10pm. If they could just fix the GPS issues with a software patch (they say they're going to sometime in September, along with an upgrade to 2.2) the I'll be extremely happy.
Also, I've been pretty happy with the brightness of my Captivate, I wonder if the review took into account the separate brightness settings for the browser app?

These results were all recorded after discharging the phone more than 3 times (each test was run multiple times). Note that 4 hours of continuous usage can often times yield a pretty long real world battery life depending on your usage pattern. That being said, a phone that gets 8 hours in our tests will obviously last longer with the same usage pattern. While the Epic 4G's battery life may be sufficient, it's lower than we'd like to see for a modern smartphone.And thank you for the correction on the browser brightness setting, that's why the screen looked dimmer at full brightness by comparison. In that shot the Epic 4G's screen was set to approximately 20% brightness. I've made the appropriate correction in the review and credited you with the heads up :)
Take care,
Anand

Anand, the poor battery life is probably due to Sprint. Other reviews (of the European 3G galaxy S) show maybe the best battery life among Androids. Check this test from a very reputable site: http://blog.gsmarena.com/samsung-i9000-galaxy-s-fu...
