GPS Issues
Every smartphone has its sets of issues. The iPhone 4 has its antenna problem, the Palm Pre has performance issues, the BlackBerry Torch needs a bit more oomph in the software department, and every Android phone has its own set of strengths/weaknesses. The Epic 4G is no different. In addition to the absolutely horrible battery life, the Epic has a pretty serious GPS issue.
The GPS antenna is not very sensitive and usually has trouble locking onto GPS satellites. This manifests itself in two ways: the phone will take an inordinate amount of time to determine your actual location, and/or it won’t pinpoint your location very accurately.
Sometimes the Epic 4G will lock on perfectly and quickly, but usually it takes several minutes longer than the Nexus One to figure out where you are. Occasionally I even got a ‘location not available’ error while using Google Maps.
Accuracy is also a problem. I don’t think I ever saw horizontal error drop below 30m on the Epic 4G compared to ~3m on the Neuxs One and ~5m on the iPhone 4.

The Epic 4G would usually tell me that my physical location was somewhere down the street while the Nexus One would pin me down at my house. In fact, I got more accurate location tracking when I was connected to a WiFi network.
It’s unclear whether this is purely a software problem or a fundamental antenna design issue ala the iPhone 4. One thing is for sure, if you plan on using GPS location a lot you should avoid the Epic 4G.

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...
