[Q] Qi Wireless Charging and Overheating [TYLT VU Specific]
I purchased the Tylt Vu wireless charger for my N5 and N7. Last night, before I went to bed, I charged the N7. In the middle of the night, I switched out the N7 and charged the N5. When I woke up this morning, the phone was too hot to touch, and had been powered down (as designed, based on the heat). It took about 5 minutes before the phone was cool enough to power on.
A couple questions: Can such extreme (??) heat do permanent damage to the phone? Has anyone else had this problem with the Tylt Vu wireless charger? The phone wasn't off-center, and nothing appeared abnormal when I set it on the charger. I wonder if transitioning from the N7 to the N5 so quickly caused an abnormality?
I haven't been following this thread, as I decided after my overheating incident to no longer use the Tylt Vu with my Nexus 5. I was also a bit turned off by the response I received from Tylt.
I take no credit for the following information, I am only summarizing this thread to save you time.
The Tylt Vu is defective. It contains three charging coils that help it to charge any device without having to be finicky about positioning. However, unless you set the Nexus 5 onto the Tylt Vu in a specific manner, the third (top) coil will remain activated, resulting in overheating due to the magnets present in the Nexus 5. (Oversimplified explanation... read the chain for specifics.)
The "right way" is to set the Nexus 5 down in the crevice of the Vu, perpendicular to the earth, and then pivot it down to rest on the back of the Vu. The wrong way is to slide it down the back, or otherwise set it on the Vu in a way where it is not touching the short base first. (See post #118
.) You can also permanently disable the third coil by opening up the Tylt. All of this applies to charging the N5 in portrait mode.
A big thanks to NCguy for his persistence throughout the thread, to Mr. Sprinkles for his theory and relentless testing, to jelledgeu2 for the "solution", and every other poster who has shed some light on this. And a big 'no thanks' to Tylt for their response to the issue.
Always be vigilant on how you set the N5 on the Tylt Vu, or charge the N5 on the Tylt Vu at your own risk.
