I have my phone oc'd to 1.2ghz. When I turn my screen off I have to take out my battery to restart it. Is there a fix without me having to lower my speeds? Thanks

I had a problem when i set my speed to low for when it was off. Have you changed the speed for when it was off?

That has seemed to work. Thanks, didn't know it would be so simple. I have it set at 600 mhz when screen is off

Does anyone know any good apps to check cpu usage that is known to be accurate, I have installed system panel and system tuner pro, both show all 4 core usage with on and sleep if cpu is not in use, the problem is all core 0,1,2,3.
both display different core in sleep mode at at the same time, example at the same time system panel shows core 1 and 2 in sleep mode, while system tuner pro shows core 1 and 3 in sleep mode, or just core 0 running and the other 3 sleeping.
so how do we know which is accurate and are these apps really that accurate.
thanks in advance.:victory:
CPU Spy
Check CPU SPY... Accurate and does not use any resources
anything to check all 4 core.
thanks
Hi,
Sorry, nevermind. Wrong reading.

system panel and system tuner pro are the one's installed already, both give me different results.
you can read my first post about the problem.
thanks
Cool tool

Hey everyone, i Was wondering if it is possible to disable the 2nd core so it will run single core?
When checking System tuner, I see the second core jumps to 1.9 ghz some times, when using XSX kernel.

Its always sleeping... Works only if you multitasking or playing games... Anyways try cpu sleeper from store... Don't know if it works for Xperia S..

You on xsx kernel?

I'm on stock kernel that come with .50. CPU1 is offline most of time! And it's still perform very well!
Don't forget to hit thank, if i deserve it!

what's the main reason you want this?
The benefit of having 2 cores is that you can better multitask. If you want to save battery you could also try underclocking your cpu.
You would still have the benefit of multitasking with 2 cores and saving battery. (of course your phone would be less powerful, but that also goes for putting 1 core down)
I see cpu1jumping to 1.9 ghz a lot I dunno if it's a bug or what but doing nothing and just idle with screen on it jumps up from offline to 1.9.
So I was just wondering if it's possible to turn it off completely or make it jump to a lower clock.
Battery is good if screen turned off, but screen on it consumes battery fast, and my clock is normally 1.5 ghz ondemand, and cfg

Hi all, just been having a problem with my battery draining right down after a full charge at night, then in morning the phone is dead ..i always make sure there's no apps running in background by using the Active applications monitor, i don't use any of the Task Killer apps.. i can't understand how this is happening over night after a full charge and there's no use of the phone coz i'm in bed ...its happened three nights in a row now..
Any help on this is much appreciated...thanks :crying:
Can you install CPUSpy app? And post a screen shot of the result it seems that your phone is not going to deep sleep.

Hi, ummm how do i do that? not very technical i'm afraid lol.. it never used to do this drain right down to the point my phone is dead in morning
Download the CPU spy app from the play store. Let your phone run for about a day or so and then check the CPU spy app. It'll show you the various speeds at which your CPU has been running and for how long it stayed at each state (speed)

I have been reading in many threads in the Xperia Sola/P/U sub forum that one should turn off auto rotation to save battery if that feature is not being used.
I used to do that. Until yesterday evening while playing Temple Run, when a doubt came to my mind.
Since auto rotation is turned off. But the guy in the TR2 picks up movement from tilting the phone also. Which means the gyroscope (on whatever device that is used to measure angular movements) must be running even after auto rotation is turned off..
So if gyroscope is still on, is there any actual battery saving?

Yes is for Turing it off disable sensors and it saves battery

By turing off auto rotation means
Screen will not rotate while in normal apps, gallery, brpwser etc
It doest mean it will completely turn ur senor off...
Games require gyroscope so it will run while playing
Sent from my Xperia U using xda premium
That will turn off sensor for screen rotation but not for games.
But if you arent playing game and you have autorot turned off you are saving battery
Ps sorry for my bad english

If Auto Rotation off disables sensors, how are games still able to sense movement.
If auto rotation off does not disable sensor, how is battery being saved?

Games are exceptions tell me rotation of ui is more frequent or playing of games use common sense and if you don't believe thn observe it

It does disable the sensor, but when you install some apps (games in paticular that use the gyroscope and stuff) they have the permission to turn it on, but outside of that app it will be off. Very simple actually

Okay... Your explanation nailed the question.
Got my answer.

Turning off autorotate will not save your battery.
Also factor in the negligible savings from cpu not polling sensors, or processing animation for rotation.
It will NOT save your battery at all...

See my previous post. However small, a saving is a saving.

I know. Just wanted to point out that your previous post was factually incorrect. The quoted one is true tho.
