Hello Everyone,
I wanted to post up something I have noticed. I have the Nexus 4 I also have the OEM wireless charger. At the time of the observations I also had the Skinomi TechSkin front and back cover installed.
In regards to wireless charging it is known to generate extra heat, its a downfall of the process. The Nexus 4 design with its glass and metal build is good at handling this.
I have charged my Nexus 4 on wireless many times and at first while I still had the Skinomi installed I noticed the phone was retaining heat, this freaked me out. My last phone was a Nexus S and heat was the downfall of that unit, if it heated up to many times it broke down components like the power button.
So why was my phone retaining heat? Well I narrowed it down to the protective skin. It is my assumption that there was particular design considerations in the development of the Nexus 4. The Glass/Metal body was put into place to help with the radiating of the heat away from the body over the whole of the surface. When the protective skin is placed this process is hindered.
I removed the protection and then attempted another charge. Heat did build up as before but the phone became cooler quicker.
My conclusion to this is the use of applied protective skins may cause future heat damage to the phone.
This is only my observation though. I would really like to hear from others on this matter.
My nexus does indeed hold more heat for longer with a nilkin case on it while charging wirelessly.

Hello,
I have this generic horizontal case that I grabbed at a local Best Buy store. I can't find it online to link to it, but the case has 2 rather strong magnets on the flap that when closed are right smack in the middle of the battery.
When the phone is in the case, within minutes, the phone gets relatively hot. If I remove it from the case, it cools of in a matter of minutes and never gets hot while out of the case.
I'm pretty sure the on/off switch is not being pressed while in the case, its recessed a bit in the case.
I'm wondering if those magnets are what's causing the phone to get much hotter while in the case.
Any ideas?
Thanks.
I'd bet the magnets are causing the phone to go into dock mode. I have the Body Glove case that AT&T sells & there is no warmth from my phone when in locked & in standby.
Dunno about dock mode, but magnetism and electricity are part of the same force ... electromagenetism. Those magnets should not be strong enough to cause any ill effects, but anything is possible. May be that one of them is over an electronic component (perhaps a transistor) and is just strong enough to cause it to "lock" in the wrong position. Perhaps docking mode ... I don't know why that would cause so much heat ... but if it locked the radio into full power transmit mode this would certainly account for the heat as the expended electricity from the battery would become RF energy and heat.
.... just theory
maybe you could wrap your phone in a towel or other such sort of insulator and see if the heat problem is still there, or open the stiching on the case and reposition the magnets, or remove them entirely and sew some velcro in their place.
Good Luck!!
Has anybody dropped their device yet? What happened? Did the screen break? Where are the weak points of this device? I suppose that if it lands with one of the corners, the damage could be hugh. The iBallz may offer good protection against dropping in any orientation. However, we don't know if it is compatible with our device yet.
The reason I am asking is that I love this device. I have a Capdase case (about 440g). I work at home these days and have the case removed. I found it a bit stupid to use the case because it added weight and bulk to this device. By itself, the PRO 12.2 is not so heavy but not so light. When I went out, I put the case on and felt the weight in my bag and while holding it. The official book cover from Samsung seems to be the lightest (about 200g). However, I read a review that the cover is fragile and it is not so protective. The Gumdrop is the most protective but it is a bit heavier than my Capdase case. It also raises the white color boundary of the LCD screen. As I rest by hands on the area near the home button, the raised boundary may interfere with my use of the device. It seems that if one wants more protection, one has to choose a bulky device like the Gumdrop and Ottobox cases. Am I right?
I have a white device. I prefer a case that has bright color like those for the Samsung Note 10.1 2014:
www.ebay.co.uk/itm/SAMSUNG-GALAXY-N...OOK-COVER-CASE-HARD-SHELL-STAND-/331059591828
(fluorescent green, orange and the reddish pink). I want it to be very light yet protective. Moreover, I prefer not to have the white area on the LCD screen covered. Any suggestion?

Hi Peter,
I couldn't make much suggestions in the way of what case to get, but I can tell you that I've dropped my tablet at least twice, in the i-BLASON case. It fell from an elevated bed and bounced along the frame supports, it must have hit them 3 or 4 times, and finally hit the floor (it fell from about 5 or 6 feet up). No damage at all, though it was horrifying to watch! The other time it fell from about three or four feet, smack! on the floor, I think face down. No damage then either. I don't know what experiences others have had with falls, but so far it seems pretty strong. I don't know how much was the case, and how much was the device, though.
I dropped my first Note Pro off the roof of a moving vehicle at 60mph . . . leaving it up there was the biggest bonehead mistake I've made in years.
I can honestly tell you that it shatters into many pieces when being run over by a truck at 60mph . . as witnessed by me through my side view mirror after i heard it tumble across the roof of our company SUV. 5 lane highway with no shoulders. I wasn't about to stop to survey the damage. Cleanup crew had probably picked it up that night as I could not see it anywhere in the area the next day I drove through the area. Either that or someone else grabbed it but it surely wasn't repairable.
Lesson learned and after a month of grieving I bought another, installed whatever case was at Best Buy at the time and went home to insure it via squaretrade. I do a lot of field work so I need to protect this thing from myself.
Thanks for the experience. It seems that for any device (laptops, tablets, phones), the corners are the week points. I bought the Gumdrop case. It seems to offer good protection but it adds weight and the entire thing became bulky. It was like carrying two Note PRO 12.2. Kind of stupid as we want lightweight devices. I found the rubber case slippery and the entire thing is hard to handle. It might be easier to drop with the case on. Then, I bought the iBall. It fits the PRO 12.2 very tightly. I don't know if it is bad to the tablet. I also worry that if I just hold a corner (the ball), the tablet may break.

It shouldn't snap in half from holding it at the corners, but constant pressure on the glass can cause micro fractures that severely weaken the screen's integrity.
So if it's really very tight, you may want to be prepared for a possible screen crack appearing out of nowhere. Especially when there's fluctuations in the ambient temperature.
So, it depends on how tight the fittings are.
Yeah, the case came for free. I agreed to review it.
I don't give a company a pass because they send a product.
Anyway, the case is bulky, but I guess it should be because it's supposed to be a rugged case.
It's well mode and adds heft to the phone.
I understand that they re supposed to protect the full phone, but I just don't like the feel of plastic screen protectors in cases. YMMV
I prefer glass to maintain feel but you aren't going to build it into a case.
The plastic on the screen did not interfere with function and readability.
The fit and finish are good.
Button presses registered with no issues.
I didn't experience any heat issues with the case on.
The cutouts on the screen and the case are spot on.
The kickstand works great in portrait and landscape.
The covers on the ports work fine and fit secure.
If I'm heading out to the beach, this is the case I would grab.
I wouldn't use it as a daily driver because I'm not in a harsh environment.
Overall a good case. I'd give it a 4.5 out of 5 stars.
Thanks for the review. This is the case I was considering for daily use at work. I'm a service tech and its a rough environment. I have the Spigen rugged for my slim case.

Just got it today. Two issues I noticed so far:
1. you can activate the volume buttons while pushing down around the area surround the case volume buttons. I already dislike the location of the power/volume buttons and was hoping a heavy duty case will help with accidental button pushes while handling the phone.
2. the usb-c power is somewhat tight. When using the usb-c cable that came with the phone, you have to push it in hard enough to start charging. It isn't too bad except if you aren't careful or in a rush, you may not actually start the charge.
edit: I take it back, #2 is an issue. Plugged in one way, can get it to charge with some pushing. Flip it around and I'm not able to get the connection to work at all... boo

Is the hole too small or not lined up perfectly?

Looking into the hole with the phone facing up, the inner plastic portion of the case is too low. It isn't obstructing the actual usb port but the usb-c connector's housing is obstructed.
Yes, I did the same thing. Immediately remove the build in screen protector and install a tempered glass protector. I did not notify the charging issue, just need to push it a bit hard, both sides work the same way.
I bought my Moto Stylus (2021) back at the end of January. I bought a Spigen bumper case and screen protectors from SuperShieldz. As I prefer a ballistic nylon carrier on my belt instead of the typical clip on type holster, There are times when the phone gets really warm.
Here's where the question comes in - periodically I lose service as if the SIM card has stopped working until I reboot or restart from power off. Has anyone else seen this problem? I bought the phone from Amazon unlocked and my carrier is Verizon. I got the SIM card from a company store here vs a franchise location.
Try a network reset.
Clear system cache.
Clear Sim toolkit apk data.
Try a hard reset (not reload).
Try updating related systems apks or rolling them back to their factory load
If you done any major firmware updates since buying do a factory reload.

Just an update - When the phone gets hot, the SIM still dies until it cools off. the back of the phone is really warm. I use a magnetic mount in the car so the plates are on the back of the phone on the outside of the Spigen bumper case.
You would think with a plastic case, a rubber bumper case, and metal plates that could radiate heat away that it should not be a problem but it is.

Most plastics have a low thermal conductive index. Insulating your phone in warm ambient temperatures tends to cause issues.
If you got thermal shutdowns happening you at a high risk of causing permanent damage.
The display is very vulnerable with it's thousands of semiconductors and if your Li battery suffers a thermal runaway event you may lose a lot more than just the phone... maybe even a pound of flesh, literally.
By the way, keep it out of direct sunlight as the heat buildup can be so swift that the thermal shutdown safeguards will be insufficient to protect the device
Hello to all,
I use my phone in a booklet phone case.
When I use the phone inside my car with Android Auto wireless I noticed that it gets really hot. I checked the battery temperature.
Especially as it is summer now, the ambient temperatures are higher than a couple of months ago.
I now have on a regular base 37-38°C battery temperature (read by Accubattery app).
At 39°+ I noticed that the phone slows down (in order to prevent heat damage).
Therefore I wonder if a head transfer tape could improve heat dissipation. I'm thinking of a tape like on GPUs in computer hardware.
I found something on Aliexpress:

My idea is to put the tape between the back cover and phone case to improve heat transfer.
Does anyone have experience with this?
Do you think that this could lead to lower battery temperatures?
Thank you very much.

It depends on the material that your case is made of. Using some kind of thermal absorbing material between the phone and the case might extract the heat from the device but if your case doesn't dissipate the heat absorbed by the thermal material, the heat will just be trapped between the back cover and your case, which isnt really an improvement.
Try a different case or no case.
The phone stays in a silicone case which is glued to the booklet made of PU.
PU does not have a good thermal conductivity. Perhaps I could add some holes so that the heat dissipation tape gets ambient air.

Maybe a small portable cooling pad like used with small laptops would help or a small 12v fan that plugs into a 12v outlet in your car.
I already thought about a fan.
I ordered an ESR wireless charger with Cryoboost (cooling fan) to check if charging would be possible with fan.
