Ok so I'm debating on updating to v1.6 (currently running RubiX v1.0) but I can do without the overclocking because honestly my phone runs just fine...but what benefit does modifying the voltage do?
I've been happy with using SetCPU to underclock my phone when the screen is off, when the battery gets toasty & when the juice runs low.
Voltage is directly relevant to how much battery is used. Lower voltage = better battery life.
What about overall performance of the battery though? If you just undervolt it can you get away with not overclocking it?
Pardon my n00bness...I've never gotten into overclocking in general (even on my desktop), just never saw a reason.
Overclocking has to do with 2 elements... clock speed, and voltage (There's a lot more to it than that, but.. keeping it simple here).
A processor comes from the manufacturer with a speed and voltage that they've tested as stable... but each chip is a little different. When you raise the voltage, it increases the stability of the processor, but will drain the battery faster, and also cause increased temps.
Some chips can run at the default speed at a much lower voltage than others... this is undervolting, and can be used to increase battery life, often without impacting performance.
Some, when raising the voltage slightly, can run at faster clock speeds. This is often done to slightly improve performance. It's unlikely that you'll "feel" the performance increase, but it shows up in performance monitoring apps, so makes people feel warm and fuzzy, and that they're running faster. (It also has other side effects, like making the device feel warmer (and possibly fuzzier..
)...
Not knocking those that want to OC their device.. just saying that it's a preference thing, AND that there ARE risks... including when you raise the clock speed, and/or voltage, it will increase the heat output.. as well as the variance in temps (hot to cold and back, over and over again), which can lead to earlier failure of the chip, etc.
Likewise, undervolting can cause stability issues.. if the voltage isn't enough for the particular chip that you have...
So to better answer your question... undervolting, and overclocking are 2 different things. When you undervolt, you are attempting to lower the voltage to increase battery life, without changing performance. This **can** lead to stability issues, if the chip isn't getting enough voltage to function properly.
Overclocking is raising the clock speed (and most of the time, the voltage along with it) for performance purposes.
Hope this is helpful!
