Does the back of the phone get very hot? (S4)

It depends on the charger base you have. I have the kool puck and my phone does not get very warm. My phone also has a water proof case on it by Sedio. Every thing works great. I am sure my phone would get warmer if it did not have a case on it. But you will like the whole qi charging thing, it is slick.

I never got hot with mine, unless it was (like Matthew said) heating the battery up for other reasons. Sitting near a window, heat duct, etc while charging. Otherwise i never got hot using the Nokia Qi puck.

Yes, it does get hot, or at least warm, but that seams more of a battery issue. My battery gets warm either way I charge it. Wirelessly or by cord depending on how fast it charges or discharge.

Your phone shouldn't get that hot unless there's a problem with the battery... as long as the battery life itself is okay, if you can put up with the warm phone I don't think you necessarily need the extra battery. My factory battery gets very warm as well and it seemed to be affecting the battery life, so I bought this product. I've been using these batteries instead of my factory battery.

No problems with the phone overheating but I have had problems with someone trying to hear me. I had to hold the phone up to my mouth on occasion.

Not while on the phone, however if you keep raking it off and putting it back on it will (the black rubber part). And I didn't have a problem with the battery over heating.

Yes you can leave it on all the time. I never had problems with my phone overheating, even if it was in my pocket.

No! The case gets extremely hot and you are lucky if you get 10% extra battery life. I returned mine for a full refund.

Nope. I usually put one four to five devices together, just the normal temp, no overheat. I have been using the charger for about two months, no issues.

Haven't had problems with phone overheating. I've used it for 30-60 minutes at a time. Sound is great. ONLY drawback, the sides are raised, makes hitting the side keys on the keyboard a tad difficult and the silicone layer at the bottom is a bit flemsy due to the big opening that's cut for the charging port.

My phone would occasionally get too hot that I had to shut it down. It wasn't only with this battery though. I experience it with the regular battery as well. I think it's just a flaw with the phone.

no problems at all. it actually helps in the warmer months as it keeps the phone cool.

I don't find that to be the case. My phone does warm up when using data/wifi but that's after quite a bit of use. I don't think the case makes a difference. I have not dropped phone (THANK GOODNESS) so I can not tell you how much it protects the phone. I like the clear case so I can look at the color I picked & my "signature" on the back of the phone.

I have the silver one and I've never noticed it to get very hot. Not sure about the black one.

No, I've had two devices plugged in for hours and it does not get overly warm. As with any charger it will get warm, but, it should not get hot.

Yep I use it with a S4 and it is great! I have a body hugging case on it with room to spare. I have had it for a little while now and use it daily. No problems at all! I followed the instructions that came with the device. It will not detach! I have tugged on it a few times just to see if this thing stuck like some of the other reviewers have said and it does. It is not going anywhere. I am in Southern California where the temp fluctuate from 50 degrees to 85 degrees in the same day. This thing sit on my dash outside day and night.

It may just be able to squeeze in there without a protective cover on your phone. Another problem will be the phone heating up because of very little room to breathe. My IPhone 4s has overheated when using a GPS program to track my rides and I do have a little more room than you would have.

The case does not get hot, the front panel gets very warm because that is where the hot air is coming from of course. I have been very happy with my original one. I returned the second one I purchased from Amazon because it lacked the hardware to assemble the base and the box had been previously opened.

Lucky for you. I only used mine once. It got so hot I was afraid it would damage my phone. Send it back and get a refund. Not worth ruining a phone.
