Re: [APP] [1.2] XCore Disable Core Increasing Battery Life

It doesnt full work.

At the first time, yes it will deactive one of our cpu.

But it only work for a while.

After reboot, this apps useless, my both cpu goes on and never off.

Im using cpu sleeper, and it work 100%

Question

After reading all posts, I'm a bit confused. Does this app save battery by switching one core of? I didn't see any clear answer....

I won't go and get this app if it isn't working for battery improvements.... but I'm intersted
[Sony Xperia P, U, Sola, Go] doctor_droid:
Yes it TEMPORARILY switches one of the 2 cores off to save battery

Hotplug governor is way to go, no need for stupid app (that uses cpu itself), just put this lines in init.d script:

echo "hotplug" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

echo "hotplug" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor

[Sony Xperia P, U, Sola, Go] mironkraft:
nice thanks for the job, but it has a little bug with the Xperia U where the light bar changes color and sometimes it doesnt turn off

Anyways thanks

[Sony Xperia P, U, Sola, Go] GX Dev Team:
I think it will work on all devices with dual core. But unsure 'bout this...
[Sony Xperia P, U, Sola, Go] bliveinhack:
updated to 2.0 ...try and ...let me know if there is still a bug?!!
[Sony Xperia P, U, Sola, Go] LENNUJ:
Using it now in my xgo & cpu stats for monitoring, 2nd core usage 0% so far so good
[Sony Xperia P, U, Sola, Go] guitarfreedom:
I'm trying it, seems to be ok now. I'll update my post with more informations in a few hours.

Thanks

UPDATE:

I noticed that during calls, second core starts.

And It runs randomly during normal use too.

I'm on GB on XU.
[Sony Xperia P, U, Sola, Go] japoina92:
yeahh!! now the bug of auto on the second core is fixed ( i think ) haha and no red led in illumination bar ;)

GOOD JOB :victory:
[Sony Xperia P, U, Sola, Go] bliveinhack:
After Call What's Status?

Thanks for feedback..

So u mean to say it start 2nd core during call...and randomly off after call....:confused:
[Sony Xperia P, U, Sola, Go] guitarfreedom:
Sorry, I'll explain better what's happened to me:

1. First time after install: app worked good; second core is OFF ( I turned off screen, open some apps ecc).

2. I received a call; ended call, CPU stats showed me that second core was turned ON.

3. So I turn ON persistent service in app's menu.

4. without any other call, after some minutes, CPU stats showed me that second core is ON, again.

This is my experience on my device. If I can help you with other info etc, I'm here; your app is really a good idea to develope.

Thanks for you work.

;)

PS. I've uploaded a log file:

It starts when I turn off second core through x-core app;

then I've made 2 calls;

after 1/2 minute, second core turns ON again.

I hope It helps you.

Guy the thing is sometimes when I have turned my core off my battery discharge slowly but suddenly it starts discharging very fast.Anyone having that problem
[Sony Xperia P, U, Sola, Go] JohnHK:
Two suggestion :

1. Make a widget for this app (OnOff widget).

2. Add schedule enable and disable.
[Sony Xperia P, U, Sola, Go] JohnLouise:
yes me too.
[Sony Xperia P, U, Sola, Go] bliveinhack:
Try This...

okay...try this.

1st turn off the service. and turn core ON..after this go to preferences and check bug fix mode.

back to the main screen where you will see . bug fix mode enabled. after that try to turn off the core. and let me know what happen.

thanks,

regards.
[Sony Xperia P, U, Sola, Go] nomrae:
It automatically turns on when device needs it. It doesn't stay off 0:)

Basic activities like sms and calls let the 2nd core off for a longer period of time and this really helped me extend my battery life :cool: I hope you will continue to develop this very useful app on android. Good job on this :cool:

Hello, does this work on JB roms for the xperia U?

also are there not other apps which can do this? (or a way to edit build.prop to do it your self?)

thank you.
[Sony Xperia P, U, Sola, Go] Revontheus:
This seems pointless to me... I mean why did you buy a dual/quad core phone in the first place if you were going to shut off the other core. You'd be better off with a single core device

Underclocking and Undervolting are already 2 good options to save on juice and increase battery life
[Sony Xperia P, U, Sola, Go] Wind07:
Thiz is to turn off 1 core when not needed like messaging whatsapp etc but when gaming you need the 2nd core so you turn it on :)

[HTC Droid DNA] WizeGuyDezignz:
I've had my DNA since this past Saturday and I went by many reviews and articles saying how fast this phone was. With Sense being on the phone and already going through the lag fest that was the Rezound, I was skeptical.

But I bought it anyway and the hardware and screen are beauties to be seen. Battery life hasn't been amazing but has been acceptable.

Now on to everyday usage and performance. While I'm happy to report that this doesn't have nearly as much ridiculous home screen lag that the Rezound had, but doesn't anyone feel that the home screen scrolling feels heavy? Like I was saying there isn't much lag but the transition scroll from screen to screen just feels slow to me.

I know I have read a lot of people here saying how fast this phone is, but I'm just not feeling it. Coming from my S3 it seems to crawl around in general scrolling compared to it. Just to check, I grabbed my girlfriend's S3 last night right after using my phone for a bit and it seemed like everything was in hyper speed.

I have noticed opening apps speed and in app experiences are fine for the most part. But I'm having a hard time getting over the sluggishness of this UI at the moment.

And look, I'm not looking for a pity party or am doing this to ruffle feathers. I just wanted to post my experiences to see if anyone agrees and to hear other opinions. I am still within my 14 day return/exchange policy, so I want to make sure I leave no stone unturned.

At the end of the day this phone is by no means a slouch. Not trying to say that and it benchmarks crazy well. Just noticed these hiccups and am curious to hear opinions.

Thanks!
[HTC Droid DNA] xShin:
My experience seems to be the opposite of yours actually lol. The SIII feels strange, awkward, and slow while the DNA feels perfectly smooth and snappy. Are you experiencing actual hiccups and lag? Or is it just more of a laggy feeling? It may just be the way the homescreens transition? Not sure.. but everyone I've spoken to with an SIII agreed that my DNA is significantly faster.
[HTC Droid DNA] holla420:
This phone kills everything on the s3 except sd and removeable battery.not sure what u did but my homie has the s3 and my phone smoked his ass.sense doesn't feel sluggish to me but that's just me.if u feel that way u could root it and flash a desense Rom
[HTC Droid DNA] tbns:
I think it's the sense interface which might make it seem a bit slower than the touchwiz interface. I would definitely keep the phone though :).
[HTC Droid DNA] WizeGuyDezignz:
I appreciate the responses guys, but I will have to respectfully and strongly disagree with the ones who say the DNA is much faster in home screen scrolling. I did a side by side with my gf's S3 and my coworkers Note 2 and they were both much smoother and faster in that department.

Like xShin said, it might just be how the Sense screens transition compared to Touchwiz but I can't say I'm a fan. It's to the point that it may be a deal breaker for me which is a shame since the screen and overall design is really good. Also battery life is starting to not be as good as I thought. The standby/idle battery life is fantastic. I only lose like 2% at night. But now that I'm using the phone more, the screen on time is pretty poor. I can watch it lose 1% every couple minutes.

I'm still not 100% sure that I will get rid of the DNA because there are many things that I love about it. But a few important aspects of it are letting me down at the moment.

Thanks for the responses guys, keep 'em coming!
[HTC Droid DNA] cell128:
The s3 on ICS has slight lag compared to s3 on jellybean. Trust me I have had it since launch. Also were getting a OEM 3000mah battery soon that only adds 1-2mm of thickness for an easy 6hr screen time on 4g I can't wait to get it :D

. I like the DNA but I can't go with the 16gb mine has 32gb and I also have a 64gb card
[HTC Droid DNA] tbns:
You could install the same launcher on both phones, and see which one seems quickest?
[HTC Droid DNA] earthrocker:
you want to know why the screen feels heavy? because sense 4+ has finally eliminated home screen lag that sense 4 had. they made it a uniform speed so there's never lag.. and there's not, and i have all 7 of the screens full of widgets. they changed the rosie and animations and it looks much better. The only difference is the s3 has a faster scrolling speed in touch wiz... and touch wiz is crap because e ery time you go back to the home screen, every widget redraws! for having 2 gigs of ram, it sure doesn't seem it. I have an s3 and while it's great, the dna is quicker for the most part, equal in other parts, and overall a better phone.

I've seen your posts dude. If you're unhappy, go return it for an s3..stop trying to justify keeping it with other users who like the device. If YOU don't, get rid of it.
[HTC Droid DNA] WizeGuyDezignz:
Trust me, I had the S3 since launch as well, and even on ICS the UI didn't feel as heavy as Sense on the DNA. With JB it's even a larger gap.

It's just a shame because I thought they would have learned by now that a phone with monster specs should not have any hesitation in the UI.

I know it doesn't bother most people, but I'm super sensitive to lag and slowness in a UI. And I know most people will tell me just to stop whining and get a different phone. And I get that, it's totally understandable.

I guess I am just venting because this phone has easily the best screen that I have ever seen. And as I said before, I'm not 100% getting rid of it, but I'm leaning that way.
[HTC Droid DNA] beddachedda:
Try a different launcher. Sense default transitions are 'slower' than those that you can have with other launchers.

I noticed this too, it just doesn't bother me. The phone isn't lagging, the transitions are just slower (and meant to be).
[HTC Droid DNA] lolspin:
Before getting my DNA, I'd been playing around with the Verizon and at&t s3 at work. In addition to the ones I'd handled that I set up for customers, the DNA feels just as fast, if not faster than stock s3. I'd handed it off to a co-worker with a Verizon s3 and he was thoroughly impressed by the performance and ui despite having said he has had discomfort using HTC phones in the past (incredible and thunderbolt).
[HTC Droid DNA] tbns:
This. As I mentioned above, to prove to yourself it's not the processing power of the phone that's the problem, but sense animations purposefully being slower, try out a different launcher on both phones. Confident they will be the same speed.

I mean, it's fair to return the phone if you just don't like sense and don't want to mess with third party apps or roms, but don't be fooled into thinking the processing power isn't there.
[HTC Droid DNA] Sheldor1967:
My Rezound rocks... Maybe you had a dud
[HTC Droid DNA] WizeGuyDezignz:
I've seen your posts too, and you've been helpful. Like I said, I'm not trying to ruffle feathers and I'm sorry if I have. And yes, I know I'm whining and all of that. I guess I'm just venting and trying to figure this all out.

You know what, I guess I am trying to justify it and am asking people to nudge me one direction. I know that's dumb, but it's how I work sometimes. And to be perfectly honest, I originally posted this thread and am staying active in it because I really do like this phone. I may end up keeping it after all. I was just a bit disappointed by the slower scrolling speeds, but I assume that I can get used to it like anything else!

I think I will keep monitoring battery life as well, and maybe that will end up being the deciding factor. When I had my S3, I made a vow to myself that I will never get another phone with battery life worse than that. The S3 hit a sweet spot with battery life for me.

And just to let you know, if this phone doesn't end up working out, I won't go back to the S3 but rather get the Note 2 since I already experienced all the S3 had to offer. But hopefully it doesn't come to that!
[HTC Droid DNA] earthrocker:
i hear you, man..it just boils down to the fact that if it's not working for you, gotta get rid of her, ya know? i personally love it, but then again, i also have a galaxy nexus, and a galaxy s3 to use as well. i don't sell my phones haha...i haven't gotten to play with a note 2 yet, but i have no desire to have a phone that big. seems like a giant S3 to me, and since i already have an S3, i'm content with the DNA, ya know?
[HTC Droid DNA] LANAtron:
You definitely need to try a different launcher. Install Nova Launcher, set the animations to very fast and watch it fly.
[HTC Droid DNA] luke1333:
i dont what this dude is talking about. phone blows s3 away and note II must be on crack to think it is "not so fast"
[HTC Droid DNA] intruda119:
I agree with the OP. This phone does have a slight lag to it even with another launcher. Its not much but its noticeable. I think whatever phone your coming from deteremines how you like the DNA.

And OP if you looking for a straight answer your not going to get it. Go to any phone section and make a thread like this and the answers will be the same.

Its very unlikely that your mind is playing tricks on you or your phone is defective. Its there but nothing that breaks the phone or usage.

Sense is still heavy for some odd reason and the 2gb of ram helps alot. Cant imagine what its like on older htc products without custom roms and tweaks.

Once development really starts I think all these slight issues will be worked out. I do understand that s3 has had more time to mature than DNA.

One thing the exynos has over snapdragon is media playback. Something this quadcore/2gb ram should be handling easy.
[HTC Droid DNA] kintwofan:
Op why don't you go into developers options and drop your animation scale from 1 to .5. Bet that speeds up your scrolling!

If I helped you in some way.... pass on the favor and help the next person!
[HTC Droid DNA] orangechoochoo:
I noticed people setting animations to .5 instead of off, what's the reason?
[HTC Droid DNA] earthrocker:
makes you think the phone is faster lol animations are nice, i keep mine on 1x because of that camera glitch i get at .5
[HTC Droid DNA] Memnoch73:
Thanks for that little tip. At .5 Everything is way snappier..
[HTC Droid DNA] earthrocker:
all you guys setting to 0.5x, go into the camera and try to take pics and immediately click the last pic taken icon to go into gallery...tell me if you get this weird screen fade out to black, and you ahve to turn the screen off/on to get it to work again.
[HTC Droid DNA] Memnoch73:
No issue here. Just tried it. Went right to the pic

[HTC Droid DNA] orangechoochoo:
IDK, I have all animations off and everything is snappy. I never noticed any delay with this setup. I'm using Launcher Pro with all animations off on that too.
[HTC Droid DNA] anti09:
I spent a lot of time comparing the S3 and the DNA and firmly believe they are both great phones in their own right. However, I must disagree with your assessment of speed. The DNA felt much faster and more responsive to me than the S3 does. I also hate how TW redraws widgets, which Sense never does. Actually, I just really don't like TW in general - it feels bloated and unresponsive, and I find the design to be clunky, garish, and inconsistent.
[HTC Droid DNA] milan03:
I have never been able to get the cloud animations on my home screen, no matter what scene I've tried. I know it's off topic, but what's the scene/setting?
[HTC Droid DNA] androidoholic:
Delete the widget then replace it. When you do it will come up with options check the first one and you're good to go.
[HTC Droid DNA] tgerbracht:
Nova launcher, butter.
[HTC Droid DNA] WizeGuyDezignz:
I've had animations on 0.5 since my GS3 and it makes a difference on opening and closing apps and such. I never really noticed a difference for home screen scrolling, etc.

I prefer to not use third party launchers but I will give it a try for this situation and see how it goes.

As for battery life, I'm sitting at 27% with only 2 hours and 27 minutes screen time. Pretty poor but I will see how it goes tomorrow.

Thanks guys.
[HTC Droid DNA] earthrocker:
hold down, drag it into edit and enable show animation...funny thing is they're fickle..they'll show up when they want to lol they don't always come on for me for some reason. if i unlock and dont touch the screen, sometimes they just never show..very weird.

i think ive narrowed that glitchn down to the window animation..if thats .5, it happens...at 1 it doesnt really seem to..but i have the others at .5 and havent had it happen yet..so i think its just window animation
[HTC Droid DNA] WizeGuyDezignz:
Instead of just saying that this phone blows the S3 away, how about giving your reasons? This screen annihilates the S3 screen and all others for that matter. But what else blows the S3 away?

And why am I on crack about the Note 2?
[HTC Droid DNA] Bigandrewgold:
As you said the screen

Not redrawing widgets

Overall speed

Radios

Etc.

Only thing the s3 has over the DNA is storage and removable battery.
[HTC Droid DNA] milan03:
Oh worked!

Thank you
[HTC Droid DNA] tbns:
Unless you are doing something so crazy intensive, 2 hours at 27% is ridiculous and indicative of a bad battery. I would seriously consider turning the phone in for a replacement.

I have all location data, Google Now, facebook, foursquare, Twitter, exchange push, gmail push, gtalk, and more running. Also on auto-brightness. Yesterday, with 2 hours of screen time (web browsing , etc.), all those services running , 30-40 minutes of phone calls, and 1 hour of GPS navigation, my battery lasted from 7am to 11pm, with 11% left. I can't compare to s3, but what you are getting isn't acceptable.
[HTC Droid DNA] holla420:
Wow the only poor battery life phone I've had was the gnex. I had an extended battery in it and I still only got 5-6hrs off that mofo. I've gone 21 hours off charge on my DNA. Yea take that back and get it replaced
[HTC Droid DNA] Success100:
i also find the s3 to be a much smoother afair. I do enjoy the DNA more, but everything on the s3 is BUTTER smooth. Not saying the DNA isnt fast, but It does seem the s3 has a advantage in speed to me.

Of course its because of sense. The s3 also uses full time hardware acceleration throughout the whole OS i believe.
[HTC Droid DNA] WizeGuyDezignz:
I said 2 hours of on screen time, not off the charger. After testing the battery for a couple of days now, the battery life isn't as good as my S3 was. The idle time is as good if not better, but once I actually use the phone it starts falling fairly fast and doesn't hold up.
[HTC Droid DNA] WizeGuyDezignz:
Since JB there isn't anymore redraw. Aside from synthetic benchmarks, you would be hard pressed to see a big difference if any at all in real world tasks. I will agree that the radios aren't as good as the DNA.
[HTC Droid DNA] Bigandrewgold:
2 hours of on screen time at 27% is pretty bad for a DNA. I'm at atleast 3 hours when my battery gets that low.
[HTC Droid DNA] milan03:
You should be also considering Brightness level as one of the parameters, not only screen time. I'm always at full brightness at easily get through the day, and then some.
[HTC Droid DNA] Bigandrewgold:
I keep mine at full also.
[HTC Droid DNA] earthrocker:
lol yeah there is. my s3 is running the ota and it redraws all the time still.

[HTC Droid DNA] cstrife999:
Must be just you. My S3 dies in the face of this phone.
[HTC Droid DNA] WizeGuyDezignz:
Just wanted to update this thread. I finally decided to exchange this phone for the Note 2 yesterday. In the end I didn't want to have to use third party launchers, messaging apps, etc to be happy with the DNA. And didn't want to worry about storage or battery life either.

With that being said, I appreciate everyone on this board for giving me advice, good or bad. Thanks again and enjoy the DNA!
[HTC Droid DNA] Div033:
I don't know if you would have been willing to wait, but I think 4.2 will work wonders for the DNA. I tried out CM 10.1 on my S3 and it was MUCH smoother than 4.1 TW and 4.1 AOSP. For some reason I get bits of lag on 4.1 and the experience didn't feel very "buttery". I am also hyper-sensitive to homescreen lag.

That said, who knows how long it'll take Verizon to get their heads out of their arse and deliver the 4.2 update to this phone. All I know is being on the same chipset as a Nexus device (the Nexus 4 in this case) is definitely a good thing... I envy the DNA owners in this respect, but then I pull off my battery cover and feel a false sense of superiority once more! :p
[HTC Droid DNA] stevedub40:
I agree that Sense felt a bit sluggish. After unlocking, rooting, rom'ing, and throwing nova on there, everything feels a lot better.
[HTC Droid DNA] CP24EVA:
I had a GS3 before. Nice phone, but it indeed had it's short comings as do all phones. I didn't compare the DNA to it after I bought it, but my dad was whizing around in my phone and he commented that the phone was very smooth and fluid feeling compared to his GS3. Maybe because I only had it for a few days? I don't know, but I do notice a difference myself. The only time i noticed a bit of a hiccup was when I was inside and app and went to the home screen and then it paused for about a second and then back to normal operation. Loving the phone so far. Been very smooth in my experience.
