Is it possible? Or is a custom kernel needed?
Only measure battery temperature

The sensor seems to only return the battery temp... how can I obtain the cpu temp? Is this possible from the shell?
Hi guys i'm going in the uc/oc world and right now i'm using my defy on cm 7.1 stable mod, with vsels of 300/16 600/28 1000/52, but i feel that the temperatures are a little bit high 30-38c or 41c when charging, so my question is how to achieve lower temps with no loss of performance and good battery life?
And as i'm understanding higher the vsel - lower the temp? I mean if i go like 300/22 600/38 1000/56 will i get lower temps but less battery life?
temp increases with increase in vsel (which is nothing but a factor of voltage)
Battery life decreases with increase in vsel
Stability of the system increases with increase in vsel
What ROM are you using?

Click to expand...
Click to collapse
So the idea is to have a minimum vsel to have better battery and check if the system is stable? Right?
What about clock speed? How does it affect Vsel and system stability?
the more clock speeds, more vsel you need.
high clock speed+ low vsel= crashes / low stability
high clock speed+ high vsel=less crashes / ok stability
low clock speed + high vsel= very less probability of crashes / high stability
low clock speed+ low vsel=high to med crashes / low-normal stability
So basically, it is about what you want, and how you balance it.
Well, been using the same configuration that i mentioned on the first post for about a week and stability is not a problem and almost 2 days of battery life with normal use, so happy so far
I jus t wondering does undervolt really affect our battery life? How does it work?
When choose to undervolt it affect on performance, isn't it? Slower or stuttering when switch apps? With less energy less performance, does it wrong?
If it is, then how underbolt can improve peeformance better? :confuse

Judging from my experience UV experimentation doesn't affect battery life, and if it does it's definitely by an inappreciable margin. It does substantially reduce heating issues though especially during high-intensity usage (Spotify, GNow, gaming etc). Just don't overdo it or you wind up rebooting repeatedly--"safe" threshold varies by kernel
It also has no effect on performance, it's completely separate from clock speed.
I UV to lower temperature The N4 is very heat sensitive so you'd be wise to UV if possible, the throttle can kick in very quickly on stock, because of the default CPU behavior(mpdecision+ondemand seem to ramp in a ridiculous manner). I am seeing temps in the mid-low 30s thanks to UV and I'm running turbo mode on Faux's kernel.
Im just curious what temperature you guys are getting on idle and heavy load such as antutu.
Lowest i get with idle is 40c degrees celcius and 50c with general use browser etc but with antutu i get up to 70c+ and then shutsdown.
I monitor it with system tuner and notification packages so i can monitor it real time with app usage.
I was wondering that is it possible to undervolt our GPU and has it been found yet? My Galaxy S2 had GPU UV and it had a major impact on gaming temperature. If we could control it and CPU voltages then there might be chance to avoid thermal throttling. and maybe increase battery life..
