I have extended batteries, and instead of charging them in the phone, I use an external charger and swap them out. Now the problem is the phone doesn't recognize that they are full. It stays at the previous battery's percentage and maybe goes up 5-10%, not to full like it should be. I've tried hard rebooting a few times, no dice. Help?
[T-Mobile LG G2x] Klathmon:
Lol why such high starting voltages on xlp!? I flashed it then didn't touch them for a day or 2 till i checked them to see why the phone was heating up during use, 1300mv at 864 mhz seems a bit much :)
[T-Mobile LG G2x] atb1183:
(hopefully) small request

I noticed that these kernels (and faux kernels as well) do not support time_in_state so apps like SetCPU and AnTuTu cant display it.

It's useful when trying to see if something is keeping the phone from reaching the sleep/deep sleep state.

Other than that, thanks for the great kernel work. lowering CPU voltage is a great first step to reducing power consumption. If only something can be done about wifi and bluetooth power usage as well but I know that's hardware and maybe driver issue. Not much can be done in kernel for that.
[T-Mobile LG G2x] dylyxcore:
I have been messing with my UV settings for the past two days, I have been from at least -200 across the board, now to -100 being the "most aggressive" UV. I am getting random lock ups and even SOD's. Have been playing with min at 216 and 432, and max at 1400 and 1560. Only one profile and it's screen off 216 min 432 max. Is anyone else battling the t15 or are all of you rockin' the xlp?
[T-Mobile LG G2x] I.R.Chevy:
Rocking the xlp until morfic puts out a trinity t15xlp and everyone a few posts back should know that the minimum voltage your phone will goto is 700mv so undervolting past that is useless.
[T-Mobile LG G2x] dylyxcore:
Yeah, my first three are at 700, and then slowly increased up to the 1560 OC. I took off all the UV and still get SOD in some cases... maybe it's just not stable. Going to test the XLP, it's just weird because I let it sit off the charger over night and no SOD or reboot on 8hrs with 90% batt.
[T-Mobile LG G2x] Klathmon:
Try raising your uv so your lowest voltages are all at least 750mv (keep all the higher voltages where they are) and see if the lockups continue.

I've noticed it's the insanely low voltages at the bottom end that cause most of my lockups.
[T-Mobile LG G2x] dylyxcore:
Maybe a recent flash confused the system... have you tried putting one of the batteries in, "charging it to 100%" through the phone and then calibrating? If not, it's worth a shot IMO. Use Battey Calibration app via Market aka Google Play lulz.

---------- Post added at 11:28 AM ---------- Previous post was at 11:25 AM ----------

I'll give it a try, although I feel like I have tried every combination imaginable; it's driving me insane and I am accomplishing nothing at work lolol.

Update: So far stable, thanks!

Update #2: JK fuhh
[T-Mobile LG G2x] IRASadPanda:
That's not right? On both GB and ICS the voltage for 864 is 875mv.
[T-Mobile LG G2x] I.R.Chevy:
Why not? I run 850mv for 864mhz
[T-Mobile LG G2x] Klathmon:
Ya found out it was my uv program I'm trying to make that was writing crazy values to the table :)
[T-Mobile LG G2x] IRASadPanda:
He said that the stock voltage was 1300.
[T-Mobile LG G2x] IRASadPanda:
Post deleted.
[T-Mobile LG G2x] dylyxcore:
So I think I have found the sweet spot on the t15 ICS... I think it just needs more "juice" than GB; my lowest UV is 775 and it has not locked up for a day now... good stuff. Thanks morfic for making some badass kernels.
[T-Mobile LG G2x] Klathmon:
I've noticed that on my phone 750mv runs fine until the second core kicks on, so i set my mine to 775 too :) glad you got it runnin good for ya!
[T-Mobile LG G2x] dylyxcore:
Yeah I just posted my specs and what not on Hells ICS thread... a lot of confusion using morfics over there, although I find it just needs a little less UV and it'll run stable. Check out my post and see what your running in comparison to mine. Only been running that config for a day now and had one lockup when I put it on the charger, other than that odd happening it's been running pretty good.
[T-Mobile LG G2x] nitrogen618:
Hey morfic, for the ICS CM9 kernel T15, I notice the 2nd core does not come in until 750mhz. Shouldn't it be smoother if the 2nd core comes in at around 1.2ghz? Or would it waste more battery?
[T-Mobile LG G2x] Rafase282:
Is there a Extra Low Power kernel for the AOKP or cm9?
[T-Mobile LG G2x] r.snyder:
All morphic kernels are like this. Its a pretty good balance IMO.
[T-Mobile LG G2x] I.R.Chevy:
Yep there is.

Pin it to Win it.
[T-Mobile LG G2x] dylyxcore:
I have been noticing what is really causing my instability on ICS t15 is when I put it on the charger... I made a profile for it and it seemed to help, but it's just the same as my default profile; I found this odd, but just wanted to throw it out there.

noobs be flashing GB kernels too btw on hells ROM lol
[T-Mobile LG G2x] Klathmon:
one of my friends suggested that it might be profiles that are causing lockups. Because you are forcing the phone to make huge frequency (and voltage) jumps right when allot of other things are happening (screen turning off and on, phone charging the battery and doing things it only does on the charger).

Honestly i think profiles are useless because if the phone is not doing anything it will lower the cpu regardless if the screen is on or off. And if the full cpu power is needed for one reason or another while the screen is off, forcing the speed lower will make it take longer which will use more power.

Its called Race to Idle or Hurry Up And Idle. Look it up if you have some time to waste at work :)

Edit:

Profiles are useful in other areas. For example i use them in my car to reduce the cpu because the phone is in the sun and playing music over Bluetooth with gps and screen are on, so i reduce speed to reduce heat :)
[T-Mobile LG G2x] morfic:
Actually T15-ICS will come on earlier than it used to since i kept the on off points for xlp to build a quick T15.

Ideally i go back to the old points and keep the current only for xlp.
[T-Mobile LG G2x] jookdakang23:
Which kernel is the majority of you using for ics roms? Xlp or t15? I know they have different uses buts what's the overall most popular of the 2?
[T-Mobile LG G2x] Rafase282:
Is this also available on the website? I'm using AOPK for the G2x and I dont know which one is the ELP for the device/rom.

There is no ELP for CM9, either XLP or T15.
[T-Mobile LG G2x] tsx2004:
Is XLP stable? Thanks.

I love ELP for cm7!
[T-Mobile LG G2x] dylyxcore:
Both are "stable", but they can be made unstable if you don't know what you're doing ie. UV
[T-Mobile LG G2x] IRASadPanda:
He has a GB rom too :p.

But yeah, some noobs over in the HFS thread are flashing GB kernels to ICS.

[T-Mobile LG G2x] coachhines:
halp!

Hello I've followed the steps you described and I've never successfully booted from flashing a new kernel over. It always gets stuck on LG logo when I power on. I tried it with Bionix 2 earlier with Trinity15 & I just reflashed it with EB 1.04 froyo with trinity 15 eb 1.04 froyo. Still stuck on LG logo! I'm using CWM 3.0.2.7. Do you guys have any solutions for this?? Thanks in advance!!
[T-Mobile LG G2x] jdkackley:
I flash the rom first. Wait ten minutes. Reboot into recovery. Wipe cache, wipe dalvik cache. Flash kernel. Reboot. It works every time for me.
[T-Mobile LG G2x] coachhines:
Thanks I'll go ahead and do those exact steps now!!
[T-Mobile LG G2x] sarni84:
ok so after u installed rom did u make a backup after getting it how u wanted? cuz these kernels r ext 4 and recovery doesnt support ext4 so anywaysif u made a backup well this is what i did i made a backup then i booted into it after the backup was done then i powered off and went into recovery wiped cache partition then went into advanced and wiped dalvik from there u hit go back then install zip from sdcard then choose zip from sdcard and just make sure u choose the rite kernel also when u put the kernel on ur sdcard make sure its not on internal memory for me its not j its k hope this helps
[T-Mobile LG G2x] sarni84:
when i said i boot into it i meant like turned my phone on and let it sit for a min then turn off

Hey morfic,I think I tweeted this to you before but, I cannot access my SD card and internal storage through USB. I am able to with stock and faux's kernels but not your xlp kernel. I made sure to redownload and re flash, but no go. I have also reinstalled my USB drivers and still no beans. Any insight to what is going wrong here?
[T-Mobile LG G2x] Klathmon:
it's a known issue on his latest batch of kernels, he said he's working on trying to fix it, till then try using cwm to mount the sdcard of you really need to.
[T-Mobile LG G2x] googleme1:

I have been getting freezes and sod's. Is it kernel or setcpu related? Should i be using pimp my cpu?
[T-Mobile LG G2x] morfic:
Which kernel?

Added UV or as built?

When does it lock up?
[T-Mobile LG G2x] chillwill11:
@morfic

For Max battery saving...how far would you personally UV xlp ics
[T-Mobile LG G2x] dylyxcore:
Until it doesn't lock up thus making it stable..
[T-Mobile LG G2x] chillwill11:
Trial and error:)
[T-Mobile LG G2x] Smallsmx3:
Yes more uv on t15. It happens when i plug in phone to charge or over long periods of charging. I thought it was profiles so i stopped using it ...i will try to not uv so much....i should prob trial and error more.....dont mean to bring up issues that are on the user end...ill let u knnow if it happens again
[T-Mobile LG G2x] tsx2004:
Using XLP. It's great until the phone didn't wake up. After 3 hours using it, couldn't wake up the phone until a battery pull. Min setting was 750mV as default running at 216mhz. Can't upped the voltage, so leaving the min as 594Mhz, 775mV for now. Will see what happens
[T-Mobile LG G2x] dylyxcore:
I had the same issues, make a "charging any" profile and same specs as your default, for whatever reason that seemed to fix it for me.
[T-Mobile LG G2x] Smallsmx3:
Tried adding that profile and it worked for a couple hours....so switched to pimp my cpu....and with the same settings i havnt had any issues today and overall performance seems much smoother. I was getting some lag here and there with set cpu. Time will tell
[T-Mobile LG G2x] stevew84:
Is there a new version on xlp? I keep hearing people talking about a new version just a few days old.
[T-Mobile LG G2x] dylyxcore:
Keep me updated on this, very interested because I am giving into the thought that the Setcpu update(s) are making it "unstable"

Thanks button -->
[T-Mobile LG G2x] nitrogen618:
lalala. Can't wait for a new CM9 kernel that has a osum fast IO ramdisk instead of the stock one. O:
[T-Mobile LG G2x] Волк:
Ok, I have an interesting one:

Have you ever been doing something on your phone, stopped to think for a second (or 15) and are pulled back to earth by your phone's screen turning off, so you quick and hit the power button? Yes? No? For me, yes, alot. And what I've had happen is that the screen flickers then goes black, I have to wait until I hear the screen lock and hit the button again, which causes the screen to flicker into an "off" state (maybe this is where the screen lock comes in, sorry kinda out of it today) and I can now turn on my screen.

Happens on T15 and XLP, running XLP with no additional UV, with and without screen profile for min frequency.

I installed a log cat app the other day to try to catch it but the app ate my battery life to worse than stock.

The only other issue I've had is rebooting and shutting down. It won't reboot, period. I can use Droid explorer to reboot to recovery with out a problem though. Phone just freezes, requiring a battery pull.

Again, both Kernels no added uv, and screen off profile set and not set.

I didn't bring up the first because I don't expect it to be wide spread. The latter, I do expect but no one has said anything about it. I'm running HFS 1.4, had this problem with 1.3 and EGB latest.
[T-Mobile LG G2x] dylyxcore:
Yes, and I will ramble off some things... I am still battling screen wake, BUT have found 432 min is most stable. This flicker and lock is caused by drastic voltage jumps they say, but from mine and the sound of yours, possibly linked with the ROM; remember this ICS stuff is not all that "stable" and "official". Reboot is a known issue that is causing lock ups from this kernel, which brings me the the topic that this is the first ICS kernel for our device from Morfic; I'm sure he's cooking something brilliant as an update. I can recommend you to use my settings and see how it works for you.

ICS T15:

432 min

1560 max (or 1400 if your phone can't handle 1560)

Screen off:

216 min

432 max

Priority 95

Charging any:

Same as default! (432 min & 1560/1400 max)

Priority 100

UV settings:

775 on 216

-25 on 432

(and keep UV'ing in increments of -25)

-50 on 594

-75 on 750

ect...

Why is the "charging any" profile mirroring default? IDK but without it, my phone locks up on the charger, maybe due to the "screen off" profile? IDK, but I have tried anything and everything and this has made it most stable on ICS.

Good luck, and I appreciate the Thanks Button :)
[T-Mobile LG G2x] Волк:
Thanks, though we may not be on the same page as far as my problems. I am aware of a flicker issue, that doesn't matter to me, the problem is not being able to turn the screen on, it's almost like I caught it in the middle of screen off and it doesn't like me telling it to turn on.

I did take into account that it could be a screen off profile, so I unchecked and still had problems.

I know the kernel is his first ICS build and that he's likely cooking something better up for us, but that's the point, if something is broken, he needs to know so,it can get fixed in future builds or tell us a quick latch, if possible.

These are nice kernels, and sure, I am a little annoied about the issues, it's the issues I am annoied with, not Nordic it the kernel as a whole.
[T-Mobile LG G2x] IRASadPanda:
Hah@ My phone changes morfic to nordic too, also, right now some of the init.d scripts between Hellfire Sandwich 1.4 and this kernel are interfering.
[T-Mobile LG G2x] stevew84:
that's the one I was using. I heard a couple people talking about a beta, but I guess those were testers.
[T-Mobile LG G2x] Smallsmx3:
Ive been using pimp my cpu for 24 hours with the same setup i had with set cpu. I have not had one freeze or sod. Nor have i had to do a battery pull. I really think are issues with the newer versions of setcpu
[T-Mobile LG G2x] thendless:
I noticed yesterdaythis kernel doesn't support swap like faux's kernel, is it possible to add that feature for cm7/cm9?
[T-Mobile LG G2x] dylyxcore:
Use my exact settings, other than UV (depends on your phone). That fixed the SOD or screen wake issue for me. Yes, I had the same problem where it wouldn't wake after time out or locking it manually.
[T-Mobile LG G2x] joeyxl:
so UV help with heat issues? im getting random spikes of my phone overheating. like using wifi when its idling.

P = C*V^2*F

where

P = power

C = capacitance (can be considered a constant)

V = voltage

F = frequency

heat is directly related to amount of power used (although I do not know the formula for it), but every 10% drop in voltage will net you ~20% less power used, thus generating less heat.
[T-Mobile LG G2x] IRASadPanda:
Too low voltage will overheat you.

[T-Mobile LG G2x] menting:
why is that?

too low voltage or do you mean too little current supply?

don't think semiconductors work the same way as electronics, since I work in the semiconductor industry, and I have yet hear any case of low voltage causing any heat related issues (but maybe I'm just too dumb, I don't know)
[T-Mobile LG G2x] Smallsmx3:
Yes menting your dumb and panda is always right.....im sure hes in the same industry and knows way more

[T-Mobile LG G2x] menting:
I wonder if the voltage for CPU also is the voltage for other electronic components

That's the only explanation I can think of that makes sense, but I'm sure I'm simplifying it too much.

Capacitance value is just the sum of the intrinsic capacitance that each transistor and interconnects have , and that will depend on the process node that it was manufactured on, as well as the materials used, temperature of the transistors, etc.
[T-Mobile LG G2x] morfic:
There will never be swap. It is counter productive to work against how Android works.
[T-Mobile LG G2x] nitrogen618:
Omg panda! I noticed it too, the lower I UV, the hotter my phone gets. O_O
[T-Mobile LG G2x] morfic:
You guys really make me think i wasn't crazy when i considered the heavier drain at lower voltage to be Ohm's law at work, it certainly would make sense with your reported extra "warmth".

I just thought that Ohm's law didn't apply to semi conductors and set that thought aside.

I hope that formula guy goes and jumps in so i don't end up googling this....
[T-Mobile LG G2x] sambodie:
The power consumption/heat depends on several things. Too low a CPU voltage will put the transistors in a wonky bias condition. Bias is the operating point where all the switching from 1 to 0 is best considering speed, power. Could make the current drain while not switching (quiescent current) go up and can make the current during the switching time go up compared to the specs bias condition.

Not a linear relationship because the CPU is designed for variable frequency operation and variation across each wafer/between wafers.

That is why some phones can be OV/OC a lot and others, like mine, have to stay in the range specd by the manufacturer.

Sent from my G2x running Weapon 3.0
[T-Mobile LG G2x] menting:
I don't quite get what you're saying.

as far as I know, the voltage - current relationship is like this (red line)

http://upload.wikimedia.org/wikipedia/commons/1/18/IvsV_mosfet.svg

too low of a voltage should only slow down each transistor until wrong data is getting latched.

maybe the branch predictor sees it fail internal error check, and redoes the calculation again? I have no idea, just a wild guess here. But as far as purely just transistors, I still don't understand the "bias condition" you're talking about.

btw, I use transistors in my work, but it's not related to microprocessors, so there could totally be something in how low voltage makes current go up in them that I do not know about.

edit: I asked a senior designer/manager/engineer at my work place, and he said current can go up if voltage pumps are used and the voltage is too low, but he doesn't think any processor is using that. From a purely CMOS standpoint, he doesn't see how it's possible. If the embedded cache on the processor use voltage pumps, it's possible that that portion *might* draw more current.
