[Samsung Epic 4G Touch] fiernaq:
First off I want to thank the members of this community for the priceless amount of documentation and help you have made available to the general public. Even having worked nearly a decade in the IT field as a sys admin I still don't know enough about phones to have been able to root it and flash ROMs, Kernels, and Modems without the wealth of information found on these forums. I would especially like to thank qbking77 for the countless videos covering everything from reviews to how to's on flashing and even on restoring stock to phones. If a picture is worth a thousand words then I don't know how many words he's produced in the form of his videos to thoroughly and knowledgeably instruct people like me.

My primary concern when looking for a new ROM to flash is battery life. Either because of travel or due to heavy usage, my phones tend not to last very long so I'm always looking for ways to improve those numbers. I saw that someone had started a battery life review thread for Gingerbread ROMs but noticed that it wasn't very heavily used... ie. 0 replies. My hope is that this thread won't stay that way but even if it does at least I'll have a reference to go back to when I wonder why it was that I decided not to go with a particular ROM and can look at this list and say "Oh, so it was a great ROM but just didn't hold up very well in terms of battery life."

Phone Model: SPH-D710 (Sprint Samsung Galaxy Saga II Epic 4G Touch)

ROM: BLAZER Phantom 0.1.3 [FF18] 6/30/12

OS Version: Android 4.0.4 [ICS]

Battery Life: Unplugged at 8:00am, moderately heavy use including wifi, screen set to minimal brightness, 3G and 4G both disabled, all other features at defaults. As of 2:40pm - 44% battery life. Over the course of several days with varying amounts of usage, the phone usually ends up with <40% battery life after 10 hours. On a scale of 1 to 5 I would give this a 3 for adequate but not great or superb battery life. Ideally, a rating of 4 would go to a phone with >50% after 12 hours and a rating of 5 would be reserved for >50% after 16 hours

Other Notes: Very smooth ROM, fairly simplistic but beautiful. Only encountered one issue with it regarding wifi: If the phone is connected to wifi when it locks but then you move out of range of the hotspot, when you move back into range and unlock the phone it will claim to still be connected but apps do not have connection. A simple turn off wifi and turn it back on fixes the problem. This could be due to the FF18 Modem I installed along with Blazer... I don't know enough about phones to determine where the problem is, only that it exists.

Phone Model: SPH-D710 (Sprint Samsung Galaxy Saga II Epic 4G Touch)

ROM: Calkulins E4GT EL29 (don't remember the exact version number)

OS Version: Android 2.3.6 [GB]

Battery Life: Unplugged at 8:00am, by midnight 16 hours later would usually have >70% charge. Definitely a 5 star. Don't think I ever went below 30% except that one time at the airport on a layover watching youtube vids for 2 hours straight on a 3G connection.

Other Notes: Basic. Only a few visible changes from stock and even that was due mostly to the GO Launcher EX app. Functional but not all that pretty. I'm looking forward to testing Calkulins ICS ROM to see how it compares. No noticeable issues that I encountered.
