[Sony Xperia S, Acro S, Ion] someone755:
Oh we have a thread for this. Wow.

Anyways, latest tests of mine show that 648 is the last frequency stable at 800 mV. 702 needs 812.5, 756@825 mV, 810@875 mV etc. (if anyone wants I can test this further and post my voltage table for you to try -- I'm only concerned about the lower freqs, so my testing did not go above 864).

Also I've found a way better way to stress test -- a scaling stability/stress test.

And, to clear things up, set your lowest frequency to the highest one using 800 mV, not 702. If you want to save as much battery as possible, of course. If you don't care about the potential 30 minutes less of battery time, 702@812,5 or 825 mV will still work, ofc. In fact, if you really don't care about temps and battery life but only want performance, set it to the max clock (being both the min and max frequency).

So many things to do and explain and test and compile (and install Ubuntu), so little time ;-;
[Sony Xperia S, Acro S, Ion] vordhosbnbg:
I have to disagree about that. Usually battery drainers are:

1. Display

2. Phone radio - active talk time

3. GPU

4. CPU

The only reason that CPU will be significantly draining battery is that the device fails to enter "deep sleep" mode - in other words wakelock. An app or system task is keeping the device awake, even when the display is off.

On a side note, I had the best battery life with RaymanFX's OpenSEMC ROM (so sad that he got an oppo find7 :( )
[Sony Xperia S, Acro S, Ion] mgrinwis:
Don't you think the ranking is entirely dependent on the user scenario?

If you have a user scenario in which the screen is barely used and the CPU has many tasks to do, this will result in a different ranking. Lowering the core voltage and increasing the core-speed of the CPU will make the battery last longer since the CPU can do the same amount of work much faster with the same power drain. Though I agree, in the most scenario's the screen will account for the largest power drain. Fiddling with the CPU will at least help a bit.

In the case of someone755's suggestions, it results in a snappier phone with lower power consumption whether it's significant or not: I like that the phone is snappier and that it results in less power drain! A typically win-win situation. :good:
[Sony Xperia S, Acro S, Ion] vordhosbnbg:
Well for sure!

But doing a task that,

intentionally

, is using the CPU, without needing the screen is very atypical.

High quality HDR tonemapping on background?

Cryptcoin mining, lol?
[Sony Xperia S, Acro S, Ion] mithab:
The thing is setting 648 @ 800mV uses the SAME battery as 384 @ 800mV. So why not set it to higher freq so it can race to sleep faster? or doesn't have to increase its clock speed for simple task? Also it makes the phone smoother.
[Sony Xperia S, Acro S, Ion] vordhosbnbg:
Well, re-reading someone755's post, I can see what you mean... battery life should be same or better and performance should definately improve, but by how much really?

How is this managed in the stock rom/kernel - is it with Performance governor?
[Sony Xperia S, Acro S, Ion] mamboboy:
Biggest killer for me are the Facebook and Messenger apps. I lose around 12-15% battery overnight with them, but uninstall and it's only around 4-5%

What is yours screen on time?
[Sony Xperia S, Acro S, Ion] vordhosbnbg:
Basically, my conclusion is that the Sony Xperia S screen is very power hungry, compared to other similar sized screens.

Combined with bloated, unoptimized stock rom, this results in a very disatisfactory experience.
[Sony Xperia S, Acro S, Ion] Viqw:
I'm satisfied with the battery life (mine is 1-1 / 2 years old), for me, the biggest problem is the RAM usage by the system in all ROMs

Hi guys,

[Sony Xperia S, Acro S, Ion] vordhosbnbg:
A bit longer than 24 hours with 1h30m Screen-on-time and 30m calls (phone was on 2G network mode most of the time).

Never had this.. Almost 2 hours of screen on time. Using doomplus 1.2 kernel from Chinese forum and 3.9.6 black rom.
[Sony Xperia S, Acro S, Ion] anoopvp:
Hi All,

This is my first post in xda. I am from India and I am using Xperia S for past 2 years. There is no doubt that this is a great phone. But was stuck in android 4.1.2 for more than a year. Then I searched on how to upgrade to KitKat and I came to know about PA. Then I decided to flash my mobile and I did it last week. I made some mistakes and soft-bricked it for almost a day, finally I was able to flash PA to my Xperia and was a success. I use camera a lot and the camera app was not working, it gives me a pink screen and no images.

So I decided to use Carbon and it was amazing. But the pictures delivered was poor than the Sony firmware. I was disappointed a bit. Bellow I will attach a photo taken using Sony firmware, but the images that I got after the flashing was below par and was disappointing.

Then suddenly I came across the latest posts and I am glad to know that in future release the camera will be fixed. Thank you deedwar for that.

And I can say that the effort put in by RaymanFX, deedwar and other developers are unparalleled. These guys have pushed so much and worked hard and because of that we have almost all features working on the phone. The battery life is superb with less wakes and also all features work except FM. I used to connect my mobile via HDMI, but did not try it after flashing. I hope it also works. If the camera is going to be revised then it’s a great achievement.

I also thank all the testers who contributed to the bugs. And I also would like to help you all in the future development of Xperia S. I am not a software guy, but still I believe that I can contribute and I can help in future projects.

Thank you all… And I hope I can also join you in future development of Xperia S.

Read my post again.
[Sony Xperia S, Acro S, Ion] mamboboy:
I have really brutal battery drain when I'm using my phone, so I used Better Battery Stats/SetCPU to check the CPU states, and basically it's either 1.5Ghz (most of the time) and occasionally drops to ~300Mhz for a split second (whatever the lowest is)... or it'll go into Deep Sleep when I'm not using it.

Is it normal for it to never throttle down to speeds between that? Every Android phone I've had before did. It seems very inefficient especially when SetCPU will stay at 1.5Ghz and I'm not even touching the screen.

Literally 20 minutes of browsing the web and it will consume around 20% battery!

:confused: Has anyone found or is there working Wifi Tether for the Sprint Samsung Galaxy SII Epic Touch?

Model: SPH-D710

[Samsung Epic 4G Touch] iniz94:
Almost all of the custom ROMs here come with one built into the Sprint Hotspot app. Otherwise you can download an app called "Wifi Tether" from the marketplace if you want. Much easier to just use those ROMs though since they have other benefits.
[Samsung Epic 4G Touch] xST4T1K:
If your on ics, download the newer beta version of the wifi tether and under settings choose your device as galaxy nexus, here's the link to all the wifi tether.apk's

[Samsung Epic 4G Touch] gslogen:
iniz94,

the wifi tether on the market doesnt work and I do not know how to change my OS

xST4T1K,

I have tried just about all wifi tethers from the link you provided and none work except Version 6 is seen by my computer but i still cant connect and also I went into settings and changed my device to samsung galaxy nexus and it still didnt work. But when I was using Version 6 which my computer was able to see there was no device showing galaxy nexus obviously due to an older tether.

When I bought the phone it was called Samsung Galaxy S2 but people also refer to it as epic touch 4g. The model # is SPH-D710. Is it because the phone is newer to the market and no one has created a working wifi tether for this model yet?
[Samsung Epic 4G Touch] -EViL-KoNCEPTz-:
The phone is a cdma variant of the galaxy S 2 line of phones branded epic 4g touch by sprint are you rooted? if youve never changed your kernel or ROM your kernel may not allow wireless tether to work properly you need superuser and busybox for it to actually broadcast the internet you may need to do a little research and learn how to use recovery and odin and change your ROM and/or kernel so you can have tethering support and sprint has blocked wireless tether apps on our market

I have spring samsung epic tough 4g.

I rooted it to a stock OS using a simple method I found on the web here:

http://epic4gtouchroot.com/epic-4g-touch-root/how-to-root-galaxy-s2-epic-4g-touch-newsph-d710/

I did not install clockwork mod..only rooted my phone.

I then installed the latest ver of wifi tether beta.

I cannot get it to work with Encryption enabled...it works in AD HOC mode without encryption...although, a few times the app crashed on me and one time my phone rebooted when using wifi tether app...seems pretty unreliable.

I searched for foxfi in google store....does not come up for me at all...does this still exist ?

can i install that on rooted phone?

What is your advice to me at this point?

Should I use a custom ROM or wait for a fix on wifi tether?

From which ROM are you coming? Cause, in the ROM the CWM is the integrated ... And that's the reason why sometimes the ROM needs to flash two times, means:

Flash ROM

Took out battery and put it in again

3-button-combo to CWM

Flash ROM again

Ready

By flashing the ROM first time, you get the right CWM to flash the ROM correctly ...

The battery was in if it matters for anything
[Verizon Droid Charge] d9n30:
Make sure when your in Odin , and you click PDA , that you right click on cI510_vzw .... that you right click on it and click " extract here" . Then select the PIT file and make sure repartition is the only thing checked. I just went through the same thing 5 mins ago and I have it back up running

And I had to leave battery out , volume down while plugging in usb to get into download mode. don't forget to put battery back in
[Verizon Droid Charge] Hovo:
I had everything in odin running correctly I'm pretty sure. Only repartition was checked, the md5 file was the one running through odin. I unplugged it while it was flashing and I can't get back into download mode (holding vol key down) and the phone won't power on.
[Verizon Droid Charge] trparky:
Don't check the "repartition" checkbox unless you have the PIT file selected. You more than likely wiped out the partition information on the phone when you did that.

And another thing... doing a repartition with the PIT file isn't always necessary, it's only needed a small 5% of the time.

Do you need a good clean download of the EP4D ODIN image?
[Verizon Droid Charge] imnuts:
I believe that Odin stops if you don't have a PIT file and select repartition.

It stopped me several times but I finally got it figured out . It wouldn't flash without a pit file selected with repartition selected
