Received both the anker and Hyperion 6200mah batteries yesterday. I purchased both from Amazon for about 20.00 a piece including shipping. I decided to test both of these before jumping into the 106.00 mugen 6400. I have an otter box defender case that I moved like in the other thread with the mugen battery. I did the initial twelve hour charge on the anker and took it off of charge and put it in the phone at 9am this morning and used wifi and 4G both throughout the day so far and have not been heavily using the phone too intensively, just as I usually do while I'm at work so it will be rating the battery for how I usually will be using it. It is now 3:30pm and I have done a little Web browsing on 4G and have been updating Facebook and testing all day and am currently at 92%. So far so good I guess
I am running beans build 6 with the perseus kernel with the performance profile from the stweaks guide that's in one of the forums on here. My screen brightness is at about 75%. I will continue to update as I break the battery in. Received the Hyperion night before last and charged it in my phone for twelve hours and I gave it a much harder test yesterday. I had the brightness maxed and had the phone on pretty much all day long from about 10am browsing over wifi, playing a ton of games and texting constantly, made 4 or 5 calls and was trying my hardest to drain that battery and with all of that, I finally got it down to 15% by 1:30am. Looks like I might not spend the extra on the mugen and just switch between these two every few days. Will keep updating as I break them in seeing as how these are just the initial charges and they are supposed to hit full capacity after 4-5 full charge/discharge cycles.
