I was wondering if anybody would be so kind as to give me some pros/cons about overclocking my phone. Or a link to a topic as I'm sure there already is one, I searched but could not find.

PROS: Your phone goes faster!
It goes slower while it's asleep, so more battery (as long as you program the profile in setcpu)!
CONS:Your phone might overheat.
Thanks man I appreciate the response. When you say overheat do you mean the battery, or the actual phone? haha

Idk just thought I should ask....
I just figure the phone has a failsafe. I have mine at 768 and only gets ridiculously hot when charging running Google navigation. Otherwise it's just slightly warmer. When it overheats the led flashes red green and I figure its slowing the charge or stopping it to compensate.
A computer will shutdown when the heat gets to an unmanageable level to prevent damage. I figure the phone would have something similar.

It doesnt go faster while its asleep.. It scales down like any other rom/kernel would when the phone is asleep.
If you really arent sure then dont ever use an OC'ing app. Just install the kernel and let it scale on its own.

Also the only thermometer thats close to the cpu is the battery. So its not the most accurate thing to watch since its not the actually cpu temps. Just a rough estimate. Also when it get to around 40 C then set the max clock down to around default clock speeds. Or simple just let the phone relax and dont touch it. You can also take the back cover off and let it get more air..
It doesnt get hot extremely easy, so its not like youll be sending a text and it gets hot. Its only after prolonged use or doing something thats keeping the cpu from not scaling down very much (game, tethering, or etc..)

I think he meant setcpu can scale at a lower then factory frequency. But that would actually not be overclocking =P

I haven't noticed a difference setting my phone to 245mhz when it's asleep (well positively anyway). But when I unlock it is slow to a crawl, so I just set it 528mhz all the time and my battery life is unaffected but my phone is always very spunky.I don't have fresh toast on my phone so I haven't overclocked it yet (but may eventually)
I only had issues with overheating when charging, especially via USB to a computer. One commonly overlooked side effect is that Li-Ion batteries lose capacity faster at higher temperatures. The capacity degradation is a combination temperature, charge and number of charge cycles. The ideal situation is to be at 40% charge at 0C, but the hotter the battery, the more it degrades with time.

haha.lol!
mine operates at 80-85 degrees Farenheit. thats with the UV @ stock speed.
Mine gets pretty warm when charging up, but other than that seems fine.
I've never experianced it reaching a temp that I would class as 'extremely hot' but then that's pretty subjective.
mine only get extremely hot when i'm charging and listening to last.fm at the same time, but i don't a seidio 1600mah battery, so that could be causing it too...
30C here while idle and not charging, 33C if charging by USB. I guess it goes up to about 40C when plugged into a wall charger.
It does get hotter after playing games on it for a while, though.
on a road trip about 4 hours away from me, i had the navigation, music player, trapster, and lastfm was "scrobbling" in the background. Mine was so hot that i couldn't really hold it in my hand. so i did a dumb thing and held it out the window. luckily i didn't drop it. I've never seen a phone get that hot before either. didn't get a temp as this is my first android phone and didn't know how to at the time. but definitely hotter than 100.
Er... if it was hotter than 100C, then you'd have gotten first-degree burns at least on your hand, so I doubt it. And can't you Yanks get on with the time and start using Celsius over Fahrenheit?
You know I mean 100*F. 100*C would be boiling water. And no I refuse to use the metric system, imperial all the way LOL. j/k
So use setcpu and use the profiles...that keeps my phone nice and cool during charging/sleeping modes.
So would I be able to use that even tho I haven't unlocked or rooted my N1?
Pretty sure SetCPU is a no-go if you don't have root access.
That's what I thought. Guess I have to root my phone.
I am really getting tired of talking on the phone for 1 minute and seeing my battery go down 10%, lol. I running Super D 1.10.2 with Juice Defender and I am using 2G. Can someone help me out? Also how do you set the Overclock widget to atleast 285mhz? Mine is currently at 528mhz but I don't know what to set the max and min at to make it 285..
If your battery is dropping that quickly, you've got some other issue going on.
Also, I don't believe 285 is a legit value for the G1. 128000, 245760, 384000, and 528000 are the "normal" values that should be run.
Running MORE software (and thus using more CPU cycles) isn't going to help you SAVE BATTERY. Quite the opposite, it'll eat it up even faster.
Alright I set it to 384mhz, hopefully it will be better. And I was being sarcastic, lol. It is most like every 30 minutes it would drop about 10-15% if I was talking on the phone.

I was watching the 2009 Google IO conference on battery stuff and the Google rep. was talking about how the stock brightness that the phone is set to automatically is the most efficient for battery life. Also, not constantly charging your phone will help the long-term life of your battery because they can only hold so many charges before going ka-put.
After having my phone for around a month, I (yesterday) decided to flip the switch and flashed myself cm10.1 and the latest franco kernel. Just now, I reached to pick up my phone (after letting it idle for around an hour and a half in my pocket), and burned my fingers. The thing is running at 46.5c when the highest it used to get for me was maybe 40-42 (watching a movie, or charging).
What do you guys think the cause is, and my best way for fixing (I dont want to go back to stock, but I will if I have to).
Thanks,

your device isnt overheating nor did it burn your fingers. human body temp is 37C, and it was sitting in your pocket at that temp, insulated, keeping warm. 46.5C will not burn you, ever. it could feel warm because the heat is escaping from the glass back to cool off. thats what its supposed to do. you have a quad core device, it WILL get warm.

think about this.. your body is 37C. 39C is a bump warmer. since your fingers are extremeties, they will be slightly cooler than the rest of your body. since they are a little cooler, your phone will feel warmer. but in reality, your battery temp is just normal, even relatively cool for being on the charger and being used.

Okay, I didn't mean literally 'burn', you're right. My point was that I picked it up and was shocked (figuratively ) by how hot it was.
Again, for the last entire month my phone (on stock) has never reached near this temperature before, even when It was actively running.
[Oh and jacket pocket, it wasnt on me. My point was that it was in a cool, dry, place not charging, and I wasnt using it].

Okay, so saying that makes me stop worrying its going to blow up (happened to my friend's moto milestone back in the day), but it's still a new occurrence to me, which cooincidentally happened right after a changed both my rom and my kernel from stock.
The office aircon is a breezy 24c no matter what day it is .
I was leaning more towards this questions, that I gathered from when i glossed over the two respective threads, but dont understand well enough to decide or check if they're relevant:
-could it be that the rom or the kernel overclocked my phone and thats why its running hotter?
-maybe theres a wake-lock (or partial lock or whatever its called), that had my phone on though it was being left alone?
-did the kernel mess with the radio so now it keeps jumping signals?
-was there an option for 'testicular irradiation' that I accidentally enabled?
Not even sure if these are the right questions to be asking. Definitely not sure what to do about it even if they are...

there could be 1000s of reasons that your device is running a little warmer today, really. it could all just be random too. as long as the battery stays below 55-60C(60C is the battery temp safety shutdown) and the cpu below 80C(95-100C is the cpu safety shutdown). you wont see those high battery or cpu temps unless your really pushing your device(cpu) or watching flash movies/playing intensive games while plugged in(battery). there are safety protocols set in your phone in case it really does overheat.

um, you run it at whatever speed you want. default, it boots up at 1026mhz, with all 4 core set as minimum, and thats recent. before that, it booted up 1458mhz hotplugging, which is still slightly underclocked. just because you have a choice of raising the cpu speed to 1836mhz, doesnt mean that is the kernel default. you should learn about what youre talking about first, before you say something silly.

there are a few out there, i use the trinity kernel toolbox app. just search cpu temp in the play store. for battery, 60C is the safety temp. for cpu, 95C or 100C is the safety temp. the cpu os near the top of the phone, thats why it feels hot near the earpiece. its normal for the phones cpu temp to shoot up while the cpu is being used. when the screen goes off, itll cool down quickly.
im using trinity kernel now and have installed the toolbox and it shoe 1026 hz clock ??
why is it undervolted ?

Thats not undervolted, and I suggest you dont touch voltages atm and if you do make sure "set on boot" isnt checked.
That speed is just set lower, not sure if that kernel does that for you but you can set that higher if you wish.

Thread also here: http://rirozizo.blogspot.com/
Hi,
Soon to be RC here, and my first contribution to the nexus 4 world is an attempt to convince you that your nexus 4 isn't overheating.
Some of you replied to my first thread here about what should i worry about in the nexus 4. Some replied that it has a battery drain... that i fixed by removing the google search bar... Others have said that it has overheating issues which some users are scared of.
I'm here to show you why you shouldn't be scared at all.
I was playing Fast And Furious 6: The Game, and 5 minutes later when i ran out of car gas, i closed the game and directly opened Trickster MOD app to see the temperatures of the phone... yes temperatureS.
You'll notice there are two temps in this app: Battery Temp and CPU Temp.
The one you used to check on older devices is Battery Temp, because older devices didn't have CPU Temp sensor.
When i first opened Trickster MOD it showed this:
Battery Temp: 42°C
CPU Temp: 56°C
And then seconds later, the CPU Temp dropped to 49°C and stayed at 49-50°C.
But Battery Temp was decreasing slowly from 42°C to 38°C in about 5 minutes.
Now the reason for the fast CPU Temp drop is that when the CPU is busy, there is so much electricity running through it, it generates heat. But when the CPU is practically resting, the electricity running through it is much less, hence, the Temp drop, which is normal. And also, if you're using a kernel that supports turning off the 3 other CPUs when not in heavy use, then it's better because the less CPU cores active, the less heat.
So the main thing you should be scared of is the Battery Temp... But don't be, because Android is smart:
Android has a built in overheating system which does certain steps to avoid hardware heating damage, if the phone overheats, it takes some steps:
1- If charging, it stops charging to reduce Battery Temp.
2- Reduces CPU speed automatically to make less electrical current run through the CPU, thus reducing CPU Temp.
3- If both of the above failed to get out of the overheat situation, it shuts down the phone.
So if you were playing a big game, and the phone heats up... keep playing that game, android will take care of the rest
OFF TOPIC:
But the question still remains: if I'm charging the phone using the wall charger, and I put it on the wireless charger, will it blow up?
Well, yeah. This is what we have been trying to say since the Nexus 4 came on the market.

i like what you wrote, except for one thing..
"So if you were playing a big game, and the phone overheats... keep playing that game, android will take care of the rest"
the use of the word overheats. its not overheating. its heating up with use, which is the normal way things work. by using overheating, you make it still sound like an issue.

Good topic and solid explenations.
But, Do you think theres a chance the glass back will crack if the phone is at its hottest point(right before it shuts down itself)?
Because I remember that I've read these horror stories before I bought the N4, don't really know if its bad luck or not.

if you drop it in cold water, or stick it into a good freezer at that point, then yes. otherwise, probably not unless it get cooled down extremely fast.

Glass doesn't break/crack because of heat, glass breaks because of the fast temperature variation... in this case 2-4°C max is the variation, so no

Thats true, thanks for clearing it up!
Also android itself doesn't have anything built into it for thermals.
That is done by either a file like thermald or on a hardware level.
It's like saying windows controls the cooling on your pc.
A device example would be the rlod. Lower level stuff. Android isn't even loaded.

you're right, it's not "coded" into android... but so far every android build i've seen has that security system.
but that's not the point, the point of this thread is to stop N4 users from posting "overheating issue" posts, and not worry anymore.
I hear ya. But I am going to rain on your parade. It will never stop.
At best ( which I doubt) they are children that simply don't know much.
But the truth is they are plenty of fools and it will never stop. The level of stupidity I have seen related to this discussion is appalling.
Only way it will stop if it becomes taboo. One thread in general and any new threads about it get closed down and deleted.
Actually it is android that controls temperature throttling. Or to be more precise the android kernel. Which reads the thermald file for it's Max CPU temperature.
There are also hardware cut offs 100°Cpu and 60° battery which will power off the phone.
These temperatures are what I consider overheated. Anything below or throttling is to prevent your device from overheating
