[HTC Sensation] DonJuan692006:
I've been seeing some weird issues with battery since flashing B9 running CM A9. I flashed the kernel last night and then let the phone charge overnight. I'm currently using FauxClock to control CPU freqs and voltages. With my min/Max at 192/1.08 with the conservative governor and a -75mv UV I was seeing some rather sluggish response from the phone throughout the morning. I pulled the phone off the charger around 6 a.m. and listened to music through my 45 minute drive in to work with the battery showing 99% upon arrival. Put my phone on vibrate and didn't touch it again until around 10 a.m. and noticed I was down to 78%. Back in the pocket until around 3 P.M. when I left work. Started listening to music on my ride home when, after about 20 minutes, I got a phone call and the dialer application crashed (the incoming call screen never showed, just my ringtone playing). Thinking it was the governor or because of an unstable UV I switched to ondemand and returned to normal voltages. The sluggishness died down but didn't go away. I got home and was reading about people seeing graphics performance improve using the Chain Fire OPENGL drivers, so I installed them. After ~45 minutes of Angry Birds my battery was showing 1% (this was around 6 P.M.). I put the phone back on the charger and let it get to 55% before pulling to go to dinner. About 30 minutes ago, around 11:30 P.M. I was showing 45% battery. Got an update for the ICS theme that started causing the Market to force close so I conducted a reboot and I'm now showing 4% battery. Not sure what info I can pull to help but if anyone can throw something at me to run from ADB or terminal I'll be glad to post it.

Could anyone post a link or mirror to beta7 since the original link isnt working? :(

[HTC Sensation] LoveistheGroove:
I've been on the same cm7 ROM & got great battery life...12-15 hours without needing to charge it, with plenty of texting, Facebook & photo taking...and after flashing Beta 9 I was at 8% in 9 hours, and i didn't use my phone today. I had Wifi, BT & GPS off, & was in an area with 4 bars. This is only with the most recent kernel, Beta 9.
[HTC Sensation] kboeckx:
CM A8 + faux123 0.23b9

I charged my phone yesterday evening to 100% (even did a batt. calibration)

the base current is good - arround 40 mA - but the spikes are not good.

SelfKang Alfa 8 has still the same issue that the phone can't go to deep sleep mode.

What a bummer :(
[HTC Sensation] whynot66:
Current widget doesn't work. Last night I idled for 6 hours and used about 7% current widget says the lowest I used was 149mA if ghisvwas the case if have like 12% left not 93%
[HTC Sensation] gol_n_dal:
What combination of CM & Faux Kernel are you using ?
[HTC Sensation] whynot66:
SelfKang Alfa 9 and 0.2.0. Just to not I'm not actually getting good battery usage. Screen on is tricky and....

This is with no wifi or mobile Internet or sync.... And 2g only

I have the xe 1730mA battery so 7% In 6 hours isn't good if I'm correct that's like 20mA pH with I consider high with no sync or connections

And when the screen comes and the processor kicks on it different...... Ill get there in the end
[HTC Sensation] gol_n_dal:
Faux made quite a few changes with the 2.3 Beta Kernels. I'm on 2.3b9 and apart from a cpu1 issue which is believed to be in CM7, I seem to be getting a reasonably slick system, I've applied both UC & UV.

It might be worth giving the 2.3b ones a go.
[HTC Sensation] qiuness:
i`d really like at least a hint :)

thanks!
[HTC Sensation] kboeckx:
First of all, do a battery calibration. Read http://xdaforums.com/showthread.php?t=937080 for more info
[HTC Sensation] marcjw:
Many (most?) of us have moved on to Faux's beta program which means there's only one RCU to choose from (Joe's RCU) rendering your question moot.

There have been posts earlier in this thread that have discussed your exact question. You'll have to use search to find them, I'm afraid.
[HTC Sensation] Razpr:
weird. i flashed this and on the Kernel Version it says 2.6.35.14 CM7 faux v0.2.3b+ (says 3 there, is that the 3rd beta or is that 7th beta?)

Another quick Q. I installed Faux Clock via pretty much downloading the APK and putting it in the /system/app folder and installing it (and it installed just fine i guess?) but for some reason its not keeping the settings and they keep reseting when i reboot the phone. THis happening to anyone else or any way to fix it? i beleive i have Faux Clock 0.75
[HTC Sensation] DonJuan692006:
Don't think its a calibration issue. Downloaded 3c's Battery Monitor app and I'm showing 285-550 mA drain constantly with 285 being when the phone is sitting idle and the screen on. Only have wifi turned on. If its a rogue app, how would I track it down?
[HTC Sensation] aNYthing24:
Why is your phone awake so much? I'm on Alpha 9 and my phone is never awoken that often.
[HTC Sensation] kboeckx:
That's what Faux is telling us ... CM7 keeps CPU online so phone can't go into deep sleep ... and keeps the phone awake...

---------- Post added at 07:11 PM ---------- Previous post was at 07:10 PM ----------

How to track this down ? Read the thread ... http://xdaforums.com/showthread.php?t=937080

Weird. Guess it doesn't happen to me as badly as it happens to you.
[HTC Sensation] awesam:
kmobs is not supporting any longer and have moved on to another phone :(
[HTC Sensation] LoveistheGroove:
Who is the primary supporter of CM7 now for the Sensation? So many devs I love sold their Sensation. I wish I would've waited for the GS2. If not for CM7, I'd chuck this thing at the wall.
[HTC Sensation] :
Where is faux's beta program (newer beta kernels)? I'd like to check it out.
[HTC Sensation] sjgore:
A post from a CM7 dev stating whether the Sensation is still being developed for would be greatly appreciated, even if it is bad news.

I think I'd rather sell my Sensation for a better supported CM7 phone, than be forced to go back to a Sense ROM, especially if ICS/CM9 starts to appear on other devices in the next few months.
[HTC Sensation] shawayne21:
Beta 8 had the best battery and was pretty stable, only thing was the recording video would reboot the phone.

Any fixes on the camera? If so I'd stick with b8 :D
[HTC Sensation] hev88:
cret45, shane francis, and tony layher are the other maintaners
[HTC Sensation] aNYthing24:
It is being developed for...it's an official CM device. People need to stop panicking. Kmobs isn't the only one developing for the Sensation.

[HTC Sensation] Gillion:
I doubt we will get a nightly any time soon.

Sent from my Sensation
[HTC Sensation] Gillion:
It isn't so much about panic. Its more about realising the development stars are disinterested. The wave is with Samsung. It doesn't help that there are painful quirks with this phone. Awful battery life, weak antennas, weak as water speaker, new asynchronous CPU architecture that seems to be a pain in the ass. CM 7 for us slowed down because the devs have lost interest.

Sent from my Sensation
[HTC Sensation] aNYthing24:
Slowed down? How? Check around to see how often a new alpha/beta is out for CM7 devices.
[HTC Sensation] Gillion:
It has slowed down for the sensation.

Other phones get all the love, even very old units.

Sent from my Sensation
[HTC Sensation] aNYthing24:
Cause those phones have older CPUs/older configurations that are easier to develop for. The Sensation has a first generation dual-core CPU so it takes time to get all of the bugs ironed out. We are much farther along than something like the Thrill 4G or the Evo 3D.
[HTC Sensation] hev88:
Exactly... in the beginning it actually felt like nightlies for a bit. They were squashin bugs and givin us the new hotness consistently. They are focusing on the last of the major bugs/issues now. The work is a bit more tedious now so it takes longer to bring us the even newer hotness... besides the cm team members have lives of there own too in case you all didnt know. So just sit back, relax, and enjoy what we have. By the time you know it we will be in the rc/nightly status
[HTC Sensation] apex84:
I hope we'll get CM 9. I really want the HW accelerated UI on ICS more than any of the other features but I don't want to get rid of my Sensation yet to get an Android 4.0 device.
[HTC Sensation] Gillion:
That is true. The sensation has a brand new architecture.

It is also true that the old phones have a more mature code_base and know how.

However... the SG-SII was able to breach the "stable" release line... although it was rolled back because it was buggy. Still, looking at the SGII dev activity compared to the Sensation... you cant help but feel left behind.

Our sensation has many quirks, some that are not quite yet understood, and are possibly buggy.

I also dare to guess that HTC probably made some other less public errors in the sensation hardware concept.

Only time will reveal what is truly up with this platform.

However... the steam behind the sensation is low... we just can't deny that anymore...

Some of the devs I see online are showing a lack of interest in so many ways.

For example: kmobs sold his sensation long before the work on CM7 for the sensation was done ?

He's bored and wants something new... ?

That is a definite signal to me.

In my opinion there is little love for this device among many of the truly elite developers.

Buddha bless the few that stick with us.

Contracts last 2 years for many.
[HTC Sensation] aNYthing24:
I don't see any reason why it won't get CM9.

@Gillion, I'll just agree to disagree. The development for the Sensation has been fine and one of the more active communities from devices released in the past couple of months what I've seen.
[HTC Sensation] DonJuan692006:
Guys, would you mind staying on topic.

I'm still showing 100-500 mA battery drain after switching back to the stock CM7 A9 kernel so I'm beginning to wonder if the battery drain I'm seeing has to do with the ROM itself. I looked through the battery thread and I'm not seeing any crazy resource usage from any apps.
[HTC Sensation] Gillion:
I also noticed that issue.

I am going to have to flash clean after a super wipe and then load my apps one by one to find out whats cause this.

It may be messy but it might SADLY be the best way to track it down.
[HTC Sensation] cstark27:
Faux, this happens on all CM based roms for our Sensation. Hopefully it has been noticed and being looked into. Tripnmiui usually doesn't have this problem, although I did see it after doing a backup last night. I've disabled sync, privacy>backup, deleted cmstats cmwallpapers vpnservices and some others. According to watchtower, settings storage is using twice the CPU as my friends nexus one on the stock rom. But that's the only odd thing. I am running CMa8 and b9 of your kernel. I used 0% battery while I was asleep ( though not sure if its the issue where it stays at a percentage when you unplug it; it was 92%, not 100 though). Battery dies so quick though when the screen is on.
[HTC Sensation] bxlegend:
You seem to forget that Samsung is personally helping the Galaxy maintainers with getting CM7 working on the SGSII. They even gifted them several devices to develop on before the US release. HTC is not helping anyone with rom development for their devices. I hope you understand now how they manage to move the SGSII up the approval chain faster than the Sensation.

stable CM7 combination

I finaly got to a CM7 - faux combination that doesn't drain our battery.

As faux told us that CM7 selfkang a9 was pushing CPU1 to be online so the phone could not go into deep sleep ... I changed to the other CM7 rom - HyperSensation -

See attachments for my last 12 hour battery usage ...

No I'm having a normal battery drain and a usable solution for my daily work.

Faux123, thanks for the great work on your great kernel.

[HTC Sensation] qiuness:
yes just noticed that too.. second reboot in under a minute.. i guess i`ll raise the voltage to 50mV

@ -75mV -> Reboot

@ -50mV -> Reboot

@ 0mV -> Reboot

Flashing .20 back

Quite a few random reboots on this one. Changing my UV settings to find out if that was the problem. I was rock stable at 75 mv down previously, but trying 62.5 to see if it will make a difference.

Everything fine here.

Undervolted to -75mV. Working fine.

Same.. Works amazing on hypersensation. Underclocked and uv at -75. No reboots. Fluid. Now testing battery
[HTC Sensation] -juanito-:
if i undervloted..i will get better battery life ??
[HTC Sensation] qiuness:
I use the latest hypersensation as well. The way i reproduced it was:

Boot -> start voice action (Jeannie) -> say something -> it reboots every time

With .20 Jeannie works fine.

Maybe it is tied only to Jeannie and some other apps

.20 works fine -75mV @ 1.56Ghz

[HTC Sensation] Part Four:
Using the 1.78 version, but have it UC'd to 1.08 using the conservative governor. I have it UV'd to -50mv with GPU @ 50 and haven't had any problems at all. Interaction is smooth, no reboots so far, and ADW EX runs great with 3D animations, live wallpaper, and transparent 4D app drawer enabled. I've also tried boosting the CPU speed to the full 1.78 GHz and it runs stably with all other above-mentioned settings left as stated.

This is the first time I've been able to use anything other than your NoHz kernel.

Thanks.

Sadly, I take it back. Getting reboots now. Grrr.
[HTC Sensation] faux123:
Is this with the latest r_1 release?
[HTC Sensation] mrg02d:
Ill bet reboots are due to EFFIng with the cpu voltages guys. Stop messing with UVing...Theres no way in hell you will double your battery life by dropping 50mV...It is retarded to think so.

I left UVing behind and have NO reboots and NO better or worse battery drain. I used to have them all the time...Not anymore!

My battery drain is fine. It goes down to 4mA/Hr when I leave it alone for the night.

Just try it out...Leave the voltages where they OUGHT to be. The chip manufacturers KNOW what the hell they are talking about when they tell you what to use for voltage. Its in THEIR best interest to spec the lowest voltage possible, why doubt them? They do this for a living, not for fun.

If you are going to flame me, you better have some facts to back up your claim...Not antecdotal BS. Lets see some tests and results.

EDIT: Sorry to sound angry...Im not, I am just frustrated with people claiming someone's work is faulty when they insist on doing something like UVing a processor that is being asked to perform at this phone's level. Faux has done an outstanding job here. Give UVing a break and see how it goes.

Matt
[HTC Sensation] sinisin:
I have the same issue with UVing. Reboots. So I just leave it alone. Anything past -12.5 gives me rebooting issues. It says in the OP UVing may nit work for everyone. So I agree with the post above. Leave the voltages alone unless you know what you're doing.

Current draw

Hi Faux,

Everything works great with the latest kernel except that I can't get the current draw down to the levels of beta9. I've gone back to it since current drawn on that during idle is around 30mA where as with the latest the minimum I can get is around 145mA. All other setting are the same as far as I can tell, am I doing something wrong?
