I bought this one over the GTMax even though it had WAY less reviews and was slightly more expensive as it seemed to have better quality and it had a better number of good reviews compared to bad. I actually think I have YET to see a bad review for QCell. (I didn't look hard though. XD) The GTMax seemed to have lots of good reviews...and tons of bad ones as well. Some even reporting that it they got dead batteries, the battery performed worse than the stock, or that it worked great...and then quickly lost it's performance a few days later. I also kinda dislike the battery cover design of the GTMax compared to the QCell. So in the end, I thought it was worth the slightly higher price and less number of reviews. Hey, at least I can add another review to this product to help others compare?
Just received it. So far, it's a nice bit bigger than the regular battery, seems fairly well made for a fairly unknown company, etc. However, the original has "Near Field Communication" printed on it. I am currently unsure if the new battery changes anything with NFC. Also, the cover...felt a tad wrong. Doesn't "click" when you press it down and feels a like it's the tiniest bit wrongly cut. I still however got it in fine and it wasn't all that bad. The color and gloss is perfect. Looks pretty much exactly like the rest of the phone and takes away any logo or texture that old cover had, so I like that part a lot.
The weight is fine. It's like carrying 2-3 Samsung Galaxy SII's. The feel is perfect. I have big hands as some have told me, so when I hold the phone with stock battery, I have a bit of space in my hand. Like my hand is a "U" shape. The battery now fills that space up a nice bit and gives me a nice grip on the phone. I'm neutral on holding it horizontally. One side is holding a thin part of the phone. My right hand is holding the thick battery part of the phone. But doesn't bother me at all so far. I believe the GTMax's battery would win here though as the expanded shape is carried to the top with a curve. QCell's ends abruptly.
So far, I am unsure of any real last of this battery compared to the old one, but if someone could recommend a way to test both against each other, I'd be happy to test. So far, it seems like it should last at least a bit longer than the original, but again, I just got it.
Functionality: Currently Unsure
Extra Comments: Does NFC still work? The cover also feels a bit off when putting it in. Will it work longer than the GTMax ones?
