Question: Will this work if my phone has an extended life battery?  The battery is larger than the one that came with the phone.
Document: First I wanted to leave a good review and so wanted it to work right. Owned this for two weeks and after continuously having to slide it around to find the sweet spot to charge on the mat I used the factory Samsung charger while away.The jumper wire inside the case fried whole room stunk like burnt electronics leaving the powermat case useless and damaging / discoloring my phone slightly ( battery damage unknown )
I really like how convient it is to drop my phone on a charging mat, but I have noticed that my battery is no longer holding its charge even 8 hours with regular use on power saving mode. I have tried changing the battery, but had the same problem. I have stopped using it and have noticed an increase in battery life. It also almost doubled the thickness of the phone.
I have been waiting for this to come out in black but manufacture never did. I picked up this white case and wish I had not waited so long - works great. One glitch is with 'holstering' the phone now since it is larger. No one offers a suitable holster pouch for a phone this size. I would buy from this vendor again - service was quick and well communicated.
This product doesnt work from day one please dont think of this unit. Waste od time and use the money and bj uy somtjinh elsemoney
The next one came in and worked for less than 2 weeks. The plug on the bottom is very cheaply made and one of the pins bent up into the plug(same thing happened to the first one). I went back to this case, because I have 2 double charging pads and 1 single charging pad. I also have bought a case like this for my wife. My wife's case will not charge on the charging pad. So as it stands now, I've had 3 cases stop working.
It charges too slow and I wish it came in another color. Plus you can't do anything with your phone while it's charging
Works fine with my existing Powermat charging bases from my BlackBerry. Wish it came in a color other than white. And don't see why this could not be integrated into a new phone back cover. The charging points are there under the cover.
It didn't work. But that might be due to the charging port on my phone. So I bought a Qi charging mat instead. That works perfect.
It does fit the phone snugly and charge with the powermat effectively. The case covers the edges of the phone, clears the screen covers I use, and seems to provide good mechanical protection for the phone.The drawbacks, the USB OTG and MHL connections don't work through the case. Yes you can take the case off but that's a hassle. I like the shape of the duracell powermat over the palm touchstone but it would have been worth it to have full functionality on the USB connector.
I need access to my battery every now and then. It takes me a while to get this back on once I take it off.Other than that, great product. I like it. Way better than the HTC Evo version I bought.
Answer: If your battery alters how the back of the case sticks out, then this won't work. I wouldn't recommend this product anyway. I went through two of them. In both, The USB jack died and I couldn't charge the phone in the car unless I took it out of the powermat case.
