Overheating is relative. Many were seeing overheating with unsupported and warranty voiding overclocking kernels. Yes, there is more heat generated when on a touchstone charger but nothing that warrants any concern.
deff want to sell it for parts. The heatsink or something isnt right with that phone. I have the shut off sometimes and have to do a battery pull but its usually related to traveling a long distance. The pre + did the same thing when coming home from chicago . It went crazy with google maps on cause it lost the signal and shut down. I had to pull the battery to get it to start up again. SOUND FAMILIER.
My Pre gets hot only when on a touchstone (i think that the sticker that i have on HP logo is causing some of the heat - i don't want to scratch the crome ).
On the other hand, my Pre- that i bought recently (because i got the touchstone with it) gets hot while i use it for internet and watching videos.
This device is way cooler (lol @ the pun) than the original Pre. I am not overclocked, but my OG Pre ran way hotter than any of the newer devices.
I love physical keyboards... but there is two devices that would make me consider a slab, one is something running a full version of Open webOS. The other is an iPhone!!!! HA HA just kidding (about the iPhone that is)...
I've had my Verizon Pre 3 for less than a week and already noticed the increased temp when charging via USB (sits around 49 C) and I even had it shut down on me earlier when it hit 60 C (was on a Touchstone)!! I really don't wanna fry this thing, it was too expensive (not to mention rare).
I'm running Uberkernel, but just at the standard 1.4 frequency (stock 2.2.4 was giving me crazy amounts of TMC errors).
