Any one else had an issue where the CPU locks at 600 MHz while charging?it literally makes my phone unusable from the lag..

I don't have any numbers regarding CPU speeds, but, throttling while charging is common.
If not for it, the phone would likely get too hot.
are you fast charging? that could be why. I've never had this issue, but I've only fast charged it once, and I wasn't using it when I did. my phone NEVER gets hot, especially when using camera for a while, but having it on fast charger for 15 minutes it got really warm, so it wouldn't surprise me if fast charging throttles it.

Im plugged into my comp via usb to my phone and strangely once it starts charging...my phone's temp soar! Is this typical? Im seeing the temperature marks via SetCPU
Thanks in Advance
mine also gets hotter but I don't know whether it's as hot as yours, but I think a bit increasing is fine.
The higher CPU speed may be the culprit, this happened to me before. I changed my CPU speed back to normal while charging and it doesn't get hot.

I tried underclock my CPU speeds down to about 245 mhz and the temps still appear to be quite high at about 98-99 Fahrenheit? Ive also got my brightness down to the lowest setting and always Taskkiller Apps beforehand. Anyone know why the temps are still up there?
Mine gets brutally hot (45 degrees celcius) which is about the same when im charging over usb on my ps3, are you using it when its charging? also maybe your usb port isnt giving a constantly equal charge.
Odd mine is set to 358/245 for charging and of I'm not using it my temps don't go over the ambient air temp.
If I am using it my fail safe kicks in and never gets over 41c..

Hmmm...its seems like the usb port is fine
im not sure...i think its the phone's battery maybe? Becuz sometimes even when not charged...the temps are still pretty high....
Lets say ive been playing a game on an app for about 30minutes on medium brightness...I could actually feel the phone warming up
Another scenario I think could be the cause is actually my ROM maybe? Cannon's Complete Eclair has my cpu overclocked at 576mhz which isnt a whole lot any means.... but maybe it has to with the kernels and system related modifications?
Idk...im just trying to throw things out there
Anyways thanks in advance
Anyone else notice their G2 runs super hot in general? My friend with a Desire Z is able to daily use 1.4GHz...I have to set mine to on demand between 245 and 998 for it not to hit 38C+.
On top of that, my G2 gets about 40C when I'm charging which is certainly quite hot! Running Virtuous 0.7.2 w/pershoot, but it does this on Cyanogen and evil kernel as well.
Does anyone know of any disassembly shots/videos? I'm thinking I might take everything apart and re-thermal paste everything...
Thanks!

Eh... 1st of all... you're going to put thermal paste on the battery? The temperature reading for the g2 is the temperature of the battery.
2nd: I've never heard of a phone that had a heatsink on its cpu. So I don't think you'd even have a place to put thermal paste.
40c is totally fine btw.

Not on the battery! Although, that's an interesting idea...use the dry thermal pads between the battery and the door. I'm just checking if everything is getting overly hot compared to some of your other devices. Thought it may be the charging circuit having issues or something...or bad battery.
40C is fine though? At what temp do most of you have set for CPU throttling in SetCPU then? I have mine throttle to lowest when it hits that temp.

40C does sound pretty warm to me even if its while the phone is charging. I am OC'd to 1.4ghz and even when using the phone while charging, I hardly ever go over 37C.
My on-demand is set to 368/1497 and when temp>38C 245/768, although that profile never really comes into play as my temperature rarely gets that hot. Have you checked your running applications to see if there is something eating system resources? Reason I say that is because the only time my phone gets noticeably 'hotter' is after I have been playing Angry Birds for say 20+ minutes.
I wonder if its due to Variable charging currents/rates. I've noticed this is particularly problematic when i charge from say...15% battery. And yeah, Angry Birds for 20+ mins = toasty!
verkion
Hmmm, that seems a bit warmer than the norm. The thermal pad idea was a good thought though. But I'd suspect some modding to be done for it to work.
There's a very detailed teardown at http://tjworld.net/blog/htc-desire-z-tear-down
What do you consider an over heat temperature for a phone?
My g2 over clocked @ 1.42ghz reaches 108 max when playing emulators and 3d games, is that consider over heat?

Nope overheat would be like 112 or once your phone turns off its self

So could that be reason for reboots on my previous G2 where temp would reach even 115?
I remember the sidekick lx 09 use to have the overheat problem and sidekicks usually warn you with a thermometer. Sign where the battery sign goes. I once put my phone in the fridge and forgot about it in the and left it there freezing for a good hour, luckily it didn't damage but it had ice flakes all over....

Eh... Well having a phone even over 110 can damage the component within the phone, that's why one my phone even gets near 110 I lower my overclock or even turn it off completely. LOL lucky ur phone didnt get messed up in the freezer.

"Overheat" for me is when the battery cover becomes very hot to the touch. This has happened to me once.
I bought one of those el cheapo batteries from Ebay and then trashed it when I realized that my phone was no longer reading the temperature correctly.

Off-topic here, what emulators are you running on your phone?

PSX4Droid, snes, gba, gbc, and nds4droid, the latter sucks games are choppy and very laggy

My phone gets uncomforably high when I'm using it overclocked that high while I'm charging. It usually cools down for me after I unplug it, and sometimes I take off my battery cover as the aluminum heats up pretty quick too.
The lid might act as a heat sink... I dunno but just a thought. I set my alarms at 40c

This may sound stupid but is there such thing as under heating a phone or over cooling it? Cuz in the winter phone temp is usually very low even when I play emulators going to college @ the train station

Maybe, it depends on the situation. Very low temperatures will affect the LCD temporarily and maybe cause poor battery efficiency but shouldn't affect the running of the phone too much. If its cold outside, the phone will be able to dissipate the heat more.
Transition between high and low temperatures can significantly affect it though. I think its high temp to low temp, the air will condense and deposit moisture in the phone. Again, its probably nothing to really worry about, its only extreme temperature change that does that normally.
Craig
I think cellphones are made with outside temperatures between -10° and +50° C in mind.
Is anyone else having issues where they're phone locks at 600mhz and is laggy as hell?I've tried multiple Roms even stock and get the same situation..It seems that if I try to charge my phone at all this gets triggered.
apparently charging and quick charging throttles it I believe...quick charging even worse. that's pretty hot for a battery temp so yeah probably throttles.

I get the same problem even it is not charging. When battery temperature approach 40 degree,sometimes 38. The cpu scaling is locked and capped below 652MHz and become so slow to use!! It happen indoor and outdoor, so annoying
Phone: VS995 Rooted running WETA rom + Werewolf Kernel.
Issue: Phone heavy CPU throttling when charging, gaming or even just booting. The CPU throttles to 652mhz on the small cluster and 1036mhz on the big cluster whenever I do something cpu intensive for a couple minutes. Obviously this causes a lot of stuttering and lag. I have to let it sit untouched and it will go back to normal.
I've monitored the temps and CPU doesn't go above 50c when playing games and my battery temp is below 25c. Even if the cpu temps go back down to 35c, it takes a while for the frequencies to ramp back up to max.
I'm using EX kernal manager and have disabled core_control and msm_thermal but doesn't help.
I've tried the stock WETA kernel and Werewolf kernel but they both don't seem to affect the heavy throttling at all.
Wondering if there is a kernel or a fix for this, kinda like the lg g3 thermal mitigation setting, or the CTTMOD found on other devices? Or maybe my device needs to replace thermal paste?
Thanks!

I've noticed this as well on WETA but only when charging. For some reason on WETA on stock kernel this phone slows down dramatically when plugged in. I just thought it was LGs method of thermal control but on MEGAROM V4 it doesn't slow down at all for me when plugged in so idk but would like to know how to fix cause I have it plugged in during driving a lot and switching back and forth between music and navigation becomes frustrating because of how laggy it gets

Yes! That's exactly what I'm experiencing too.
Having it plugged in throttles the cpu immediately. Doesn't matter if it's a quick charger or a slow charger. The battery and CPU temps are both low so that's not an issue. Even when it reaches 100% battery and just trickle charging, it still throttles randomly.
I'll start a different rom and see if it helps.

Yeah I recommend MEGAROM V4 although I'm on the T-Mobile H918 variant and not sure if there are any discrepancies to be accounted for but give it a shot and see
Having the same issue
My phone always stay Cool even when charging but cpu frequencies keep changing.
Even when i set the cpu max to 2105mhz it automatically slow down to 1036mhz , which makes the device super laggy and shuttering.
I've tried stock rom,weta,and some other roms and also tried some kernels nothing seems to be fixing the issue but Resurrection remix rom fixed it, no frequencies changing no lag no shuttering but i also has a problem that second screen doesn't work at all :/
yep same issues stock here.. just made a topic and realized you made this lol. stock rooted fwiw. I can't stand it. this phone has become such a lag fest that the galaxy s6 I was given for work seems faster, and that's two years old.
