Try and position the phone so you get more air flow to it. Charging plus a cpu intensive program can generate some real heat fast. If it's in a weather proof case you may need a diffrent one that allows better air flow.

If ur using the cell while charging it, it will get good and hot. I've owned this product and have it on my 07 VT750 and have had nothing but good luck.

It could be a diffrance in volts/ampsI have no issues with this making my iphone hot, but it is also in a handlebar grip getting air when I ride.

A lot of times gps features in cell phones will make them get hot when powered on. Doubtful this has anything to do with charger. I would make sure output matches that of your phone's original charger.

I bought it for my 2003 Victory to charge my iPhone 5. It worked for about a month, but now I get the "charging is not supported with this accessory" message. I do not get that message using the same charging cable in my car or in my home, so it has to be this outlet. Perhaps because there is no voltage regulator? I don't know what the solution is, but my phone clearly doesn't like it. Any other iPhone 5 users having trouble with this outlet?

When I got it, I fully charged it. When I'm just on battery power. it lasts about 4 hours max. Each recharge slowly decreases the battery life. Yes, it does make the laptop hot. I use a laptop cooling pad and it keep it pretty cool. However, the pad connect to the laptop which uses more power if you're just on battery power alone.

Im not sure if its healthy or not but its happening because electricity is being transferred and with it being in an enclosed space (your purse) the heat from it charging your phone has no were to go so it continues to build hotter and hotter. If I charge my phone while it's in my purse I normally have the battery inside my purse and the phone in and outside pocket. That seems to work really well for me. :)

Mine only seemed to run "hot" if I were on a phone call for an hour+, but definitely not when idle. I've used it to take pics throughout a 45+ minute event and didn't notice it getting hot then.... Is yours running hot all the time, or are you only noticing this as you're using it (i.e. while talking / texting)? Also make sure you close apps you aren't using at the moment (flick up to close) as open apps require battery life to drain, which could be causing a heat issue....

I have never had the phone overheat. I have had it on for quite some time. That only issue I have is the charging port and how some chargers do not fit in there properly. In that case, you may have to remove the case.

Mine doesn't get that hot or even warm. It has a small cooling fan that isn't loud. I haven't mounted mine in a vehicle but under a front seat might be a good spot. You want to keep the 12 volt cables as short as possible, especially if you want to run close to the rated output.

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.

Greetings! I use it on my motorcycle so i put it closer to my engine so i could get a better idea how hot it is getting. Not sure what your using it on but the lead for the outside senor should be long enough to thread it through the firewall on a car to mount it outside. I attached mine with double sided tape and it has stayed put nicely. I'm very happy with mine. No problems for 4 years.

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.

I bought this charger and it gets hot too, I feared that the cable could be damaged from heat, so I stopped using it for phone charging and contacted customer support.

Mine got uncomfortably hot too while it was charging my truck battery back up. I set it on a brick and actually let a small fan blow on it (which surprisingly cooled it off) But after 2 days like that, it reached a point where it blinked green, and eventually went solid green. And once it went green it cooled off - presumably drawing far less current. I'd guess your battery is fairly depleted and must be given some time to charge back up. If you are concerned or feel it's a safety issue - call the company.

My phone has gotten hot, but I don't think it is because it is in a case. I usually give it a rest. My last phone got hot A LOT... this one has only done it to me once and as someone else said, it is probably from heavy use. I shut off my phone and let it rest a bit and it cooled down quickly. If this is not an option, closing all the apps not in use and just letting it sit for a little would work too.

I'm wondering the opposite, does it keep the phone nice and cool when the A/C is on? My iBolt is mounted on the window and my phone gets ridiculously hot.

Hi there. I bought this device after I used a friends Medlight 630 Pro. I doesn't get hot at all. I put it right. On my skin. On the area affected and the unit sits there for four minutes then beeps off. I then move it to another area and repeat. It never gets hot so no need to worry. It works great, my pain subsides and I feel much better. You will like it.

Right now I think thats not a bad idea. When i use it before I go to bed( since it goes off so fast I just listen to like 5-7 songs so I dont need to charge it all the time) the player gets hot quickly. And that surprised me. But thank you for helping me out Rob. I really appreciate it. Its not fair that you get to enjoy your Christmas gift while I'm dissapointed with mine. lol. But thank you for answering. :)

Hi there; If you keep the screen on continuously it will get slightly warm (but not hot) If your camera gets hot I suspect your battery will also be lasting a very short time. Best get a Fuji agent to check it out.CheersSimo (from middle earth)

I have noticed that this case does heat the phone but it does not drain the battery. I found that when GPS is left on my phone drains faster. The volume on my Galaxy S4 is on the side which is covered by the black part of the armband. This is not an issue for me since I easily adjust through the material. The plastic cover does allow you to continue to operate all of the features. I have had issues with pulling the screen down if the phone is not placed in the armband perfectly. I do like to have everything on before I start running so I don't have to mess with it. Overall, I am still very satisfied with this armband.
