Can't wait until an AOSP one comes down the pike so I can stick this on MIUI...
[Droid Incredible Android Development] nmyeti:
This kernel is really awesome. I'm using it with Skyrider's 3.3.2 and it is a huge improvement in battery life over the standard skyrider kernel. In addition, i believe this has fixed bump charging as I can now leave my phone on and charging all night and it doesn't drop quickly below 100% in just a few minutes any longer when removed from the charger.

I'm traveling this week and last night i had to remove it from the charger before going to bed (it was at 100%) so that my wife could use the outlet (was charging my laptop on the other easily available plug). With wifi on, and all data syncing, i was only down to 96% charge when I woke up. Prior to this kernel, i don't think even putting the phone in airplane mode would have held the charge like that overnight.

Did i mention that the phone charges much faster?

HTC is onto something here!
[Droid Incredible Android Development] mzmartipants:
Lol! Umm....

Anecdotal:based on or consisting of reports or observations of usually unscientific observers.
[Droid Incredible Android Development] ds28:
I want to give this kernel a shot, but as a newb I wanted to ask about the charging rate. It seems, from what people have posted, that it's extremely fast. Is it at all plausible that this rate could harm the phone or battery? I tend to leave my phone charging overnight and would rather not wake up to a battery explosion.
[Droid Incredible Android Development] jkhonea:
With it being a kernel actually released from HTC, I would be highly surprised if that happened. I've been running this several days and charge overnight with no problems at all.
[Droid Incredible Android Development] gmichaelow:
I think that bump charging is fixed! Or at least appears to be... will have to test a bit more.
[Droid Incredible Android Development] parkson:
Tried all the customs... this kernel is the goods.
[Droid Incredible Android Development] alexdw369:
Edit: wrong thread
[Droid Incredible Android Development] mbsmd:
I'm back to running the stock HTC ROM for now but I installed this kernel last night. Charged overnight, unplugged it and it went right to 95% like usual.

So for me, it doesn't solve the bump charge issue.
[Droid Incredible Android Development] bast525:
I've been running the 8/1 OTA leak with Hydra's 1.15 kernel forever.... decided to give this a try as I miss the fast charging. Charging is indeed faster, but this kernel and Rom don't seem to like each other. I get a lot of lag at random times, worst of all when I'm typing text messages in Handcent, it slows to a crawl. So.... back to Hydra for now.
[Droid Incredible Android Development] -Michael_:
Same result I had. Oh well worth a shot huh.
[Droid Incredible Android Development] jladronka:
Same here, running Virtuous 3.1 with it.
[Droid Incredible Android Development] spence341:
What Rom are you running it with? Lou put it in Redemption 2.1 and it kicks ass.
[Droid Incredible Android Development] gmichaelow:
Tried this kernel on Warm TwoPointTwo. Awesome battery life: 5 hrs awake on stock battery. Fast charging too, but I am also seeing the lag when typing.

It's interesting, because it happens to me on every stock kernel.

Try it: Type moderately quickly for more than a few seconds and the keyboard will freeze up. No vibration, no animations.
[Droid Incredible Android Development] ds28:
[I'm really sorry if this should be a "Q" thread elsewhere. I didn't know if I was supposed to make a new thread or keep it here]

I want to give this one a shot. Other than a nandroid, how can I backup/restore the stock 2.2 released kernel? (2.6.32.15). Is there a way to extract just the kernel from the ROM in case I wanted to restore it down the road without doing a full downgrade?
[Droid Incredible Android Development] spence341:
I use Swype and have no issues with keyboard lag.
[Droid Incredible Android Development] parkson:
You can get it in the skyraider or virtuous sections of Rom Manager
[Droid Incredible Android Development] gmichaelow:
I'm using the HTC_IME MOD that's default in Warm TwoPointTwo. It's funny because this "stock" keyboard and the stock kernel together lag me xD
[Droid Incredible Android Development] jbdan:
I use swiftkey and Droid2 keyboards zero lag for me it's all blazing fast
[Droid Incredible Android Development] gmichaelow:
Mmm, you are certainly right about that. But this HTC_IME is all themed and everything! Lol. Well, Droid 2/x keyboard it is then xD I know I saw some themes ones around here somewhere...
[Droid Incredible Android Development] jbdan:
The Droid2 is really nice, roomy, fast. I also tried the stock HTC keyboard was curious and zero lag as well for me. GL finding a skin I know I've seen one in black somewhere ;-)
[Droid Incredible Android Development] ozzman54:
Here's my observation after about a week of using this kernel on Virtuous 3.1.

When I charge it to full and take it off the charger immediately after the light turns green, it behaves like a bump charge and the battery stays at 100% for a while and behaves like normal.

But I let it charge overnight and have it sitting for a few hours after it gets a full charge, the battery drops very quickly from 100% to about 94% when I pull it off the charger (usually within a few minutes).

This may explain why some people are saying bump charging is fixed.
[Droid Incredible Android Development] spence341:
Same here. It drops 5-10% quick, I pluf it into the car charger and it charges to 100% quickly. Performance from there is great.

[Droid Incredible Android Development] smilesuhas:
why dont i get the fast charge time? m rooted to Sky raider 3.3.2 even after installing this new kernel the charge time still takes 4-5 hrs
[Droid Incredible Android Development] smilesuhas:
now i tried 're-installing' the kernel from ROM manager (RM), but RM is now acting weird. i tried 'installing from SD card' like i did before, but this time i got "ROM manager is unable to open this file..please remove any spaces or run it manually form clockwork recovery mode'...now there were no spaces but i went ahead and installed it from the 'recovery mode' manually but don't see any improvement.

another weird thing thts started happening with RM after the kernel update is that i am not able to install any new themes etc. like i tried installing a boot animation for SR3.3.2. it downloaded but when i clicked "OK" for 'reboot in to clockwork recovery mode and continue the installation' , it did not do the reboot.

sighhh....does the new kernel disable some rooting or RM functionality......just wondering..:confused:
[Droid Incredible Android Development] setexascustoms:
I just flashed it with SR 3.3.2 and everything seems to be working great. The charge time is definitely quicker, I'm seeing about 1% per minute. Thanks rmk40 for posting it, I really hope HTC releases the source code so some of the great developers here can tinker with it. Sadly I lack the knowledge :D
[Droid Incredible Android Development] PhillyCheez:
don't you suppose to flash through recovery?

anyways, this is the BEST kernel i have tried so far. may not have the highest quadrant scores but who cares?

charges fast and lasts the longest. nice one htc!
[Droid Incredible Android Development] billybob275:
Just curious, any ETA on when the source for this will be released? Or when there will be a way for SetCPU to work with it? I'm getting almost as good battery life as Adrynalyne's battery saver kernal with this at stock speeds, cant wait to tweak it some :)
[Droid Incredible Android Development] xShin:
Holy.. that's insane battery life! I'm using Revolution 3.2, Virtuous 3.1 with its stock kernel, and the stock battery and am only getting around ~15-20 hours up time, but roughly ~3-5 hours sake time..(that's with bump charging twice every morning)

Edit: I notice you use the redemptive revolution 1.8 along with a 9.01 radio and this kernel. My questions are, I have the exact same kernel running on Virtuous 3.1, is redemptive revolution 1.8 better than Virtuous 3.1 as far as battery life goes, and did you notice a significant increase in signal/battery with 9.01 as opposed to 7.28? Also, what exactly is S-Off, how do I go about setting it, and does it help battery life? Lastly, it says I already have this version of the kernel (2.6.32.17 -g9a2fc16 htckernel@u18000-Build-149 #1). Would installing the kernel provided in this thread change anything? Thanks for your help yet again!
[Droid Incredible Android Development] Pons:
I honestly haven't tried Virtuous 3.1 yet. I used to use 3.0.1 but recently switched. I never had a problem with Virtuous, it was just too close to stock for my taste. So I can't tell which ROM is better for battery life.

I noticed a better "locking" on 3G and have never lost WiFi. I'm also in a pretty good signal area so my radio doesn't have to ping it a lot.

S-OFF simply means your nand is unlocked. If you're running a custom ROM (to include Virtuous) you have S-OFF. To verify, just go into HBOOT, and at the top, you should see S-OFF (or S-ON).

Nope, because they're the same.
[Droid Incredible Android Development] xShin:
Thanks, you're the best :) Flashed 9.01 on my phone an hour or so ago, I'm going to see how it holds up at least all day tomorrow, possibly more days if tomorrow's results seem to be inconclusive. Also just to confirm one more time: I'll only brick my phone if I flash the same radio twice in a row, but not if I'm flashing different radios one after the other, correct? Thanks again!
[Droid Incredible Android Development] Pons:
Debatable. I've never flashed the same radio twice in a row, and don't plan to. I think it's more of one of the update scripts as opposed to the radio that bricks your phone. I just don't have enough DIncs lying around to test this theory. I have flashed 9.01 and 7.28 back and forth a few times, so that's safe.
[Droid Incredible Android Development] gmichaelow:
I didn't want to waste space, so I changed the images to links.

PosAsinorem, you've posted pictures of 9 hours of awake time with 50% battery left.

Frankly, even if you're running a 1750mah battery (assuming it is that much), that's impossible.

1750 mah battery:

Whr = mAh*#Volts = 1750 mAh * 3.7V * 10^-3 = 6.475 Whr.

The Snapdragon CPU alone uses ~0.400 watts.

Pretending your phone consists of just the CPU, that's still:

6.475 Whr / 0.400 W = 16.188 hours.

That is, the power consumption of just the processor is 16.188 hours total.

50% of that is only 8.094 hours. A far cry from "9 hours awake."

You're passing these images off as real, as being the power usage of someone actually using their phone; I believe they are not.

If I have made some mistake, I apologize, but I believe you are being deliberately deceptive.

Perhaps you could clear things up?
[Droid Incredible Android Development] Pons:
I don't/wouldn't deliberately deceive, especially not about something like the Android where I'm a relative rookie and there are a ton of people smarter/better than me at it. Too easy to be found out, obviously. And I can't remember the specifics of mathematics enough to know if there is a flaw with your formula. It's been too long since I've been out of school.

Someone else mentioned that if you look at the unplugged time, it says something like 13 hours versus the 17 hour uptime. I had just restarted my phone, plugged it in to finish charging, and then turned off the screen while I went to sleep. I thought I had double checked before I turned off my screen that it was close to 0 min, and when I unplugged to go about my day, it was still close to 0 min. Perhaps in my haste I didn't look too closely. The only way for me to verify this would be to test it again and make sure my unplugged and uptime are almost identical. While I would love to do this, I am about to be flashing a few different ROMs, and beta testing one, so I can't try to test it again, at least not right now. Sorry for any mis-confusion/misguidance I may or may not have caused.

Since you seem to be pretty good with power and voltage and what not, what do you make of this? I'm not accusing him of anything, nor do I even question/doubt it, I just want to know what your formula says about it.

[Droid Incredible Android Development] spence341:
Seriously? Maybe he has a flux capacitor that causes the snap dragon processor to use 50% less power than your estimations.

If you think this response is rediculous, please re-read the quoted text.

If you have read anything PosAninorem has posted, you would see that his contributions are many and I have not read anything that would lead me to accuse him of being deliberately deceptive.

Sent from somewhere in NH.
[Droid Incredible Android Development] Pons:
Who told you that I had the Flux Capacitor? I was trying to keep that a secret since it's one of HTC's betas. Time to wind back the time and slap you right before you go public with it. ;)
[Droid Incredible Android Development] xShin:
Haha alright, I'll be limiting my radio flashing to back and forth between 9.01 and 7.28 then :P Thanks again!
[Droid Incredible Android Development] gmichaelow:
Ah, I'm sorry for the tone of my earlier post. I was in a rather bad mood xD

It sounds as if it was just an honest mistake. The HTC awake times don't reset when you plug it back in, so that may've been it.

I just felt like there are so many who put such faith into things like quadrant scores, that they would do whatever it took to get a "high score."

It angered me when it seemed like there was yet another who seemed to just want attention. But it's never right to get angry, and so I'm sorry. And look, you weren't being "deliberately deceptive" at all, it just appeared so at the time.

In response to the link you sent me, this is one of those examples. Looking at the "Battery Use," it's pretty obvious that the phone's radio was mostly off. I'm not saying that he was trying to get attention, but he should have said that it was not actual usage. In other words, the phone was not being used as a phone. Actual usage should see something with "Cell standby" being the most, followed by "Android System" or "Phone Idle." I guess it's the fact that people are led to believe that he's walking around surfing and texting and talking and still getting that life.

Perhaps it's not "deliberately deceptive," but "unintentionally misleading."
[Droid Incredible Android Development] PhillyCheez:
anybody getting random reboots?
[Droid Incredible Android Development] Pons:
Not me. Which ROM are you using?
[Droid Incredible Android Development] PhillyCheez:
at first i was using sky raider and starting getting 3g drops...

-flashed the uncommon sense pack and the lockscreen pack

so i switched to virtuous with this new kernel... got random reboots constantly (more than a few times a day)

-flashed the rotary lockscreen

now i am using the stock ROM with this kernel... at first it was all good for a couple days but i just got two random reboots today. :mad:

-also flashed the rotary lockscreen

-notification bar icon mod to get rid of location

thinkin about a RUU to see if it fixes it, but first i am going to try a different kernel. just flashed the adrynalyn custom kernel.

i was just wonderin if anybody had any of the same symptoms.... i absolutely love the battery life from this kernel and i really didn't want to switch.
[Droid Incredible Android Development] xShin:
I just wanted to ask a question - my phone radio is always on, but my cell standby is always 2nd, with Android System being first with around 40%. Am I doing something wrong? X.x
[Droid Incredible Android Development] gmichaelow:
Lol no! But I want to bet that your %s are closer together than 94% on android system and 2% on cell standby.
[Droid Incredible Android Development] jbdan:
Not at all :D I'm bettin' your "cell standby" is in the mid 30's % ehh?
[Droid Incredible Android Development] xShin:
It's usually high 20s to mid 30s, yeah :P It goes up when I've had my phone sitting there for a while, but usually it's around there lol.

Also, has anyone noticed that after you have the phone on idle for a bit, usually the battery doesn't change, but after you start using it again after its been sitting there 20+ or so minutes, the battery rapidly drops 2-3% within a matter of a few minutes? Example: my phone was sitting there for about 30 minutes or so just bow, then I picked it up and posted this message, during which the battery went from 81% to 77%.. This happens to me a lot and I was wondering if other people had this too..
[Droid Incredible Android Development] scottylove:
Yes, I noticed this too. It appears to have some inconsistent % reporting. Still, the pros of this kernel: FAST charging, great overall battery life, and responsiveness by far outweigh this one small issue to me!
[Droid Incredible Android Development] setexascustoms:
I'm loving this kernel so far, plan on posting some real world usage screen shots tonight.
[Droid Incredible Android Development] xShin:
So its just a % reporting issue and not a random battery draining issue?

Edit: also, when you say great battery, how much awake time are you getting and what battery are you using?
[Droid Incredible Android Development] jbdan:
Curious....have you done a "wipe battery stats"? I have and feel it reports very accurately. I think what you are reporting in the above post is perfectly normal.

One of the biggest things I have noticed with this kernel is it's uncanny ability to sleep...it's super duper efficient in that regard. Also mine has a very consistent drain where as other kernels would drain fast then slow to a crawl then speed back up. Maybe some of this has to do with a battery stat wipe idk
[Droid Incredible Android Development] nmyeti:
Upon further examination, this is my experience as well.
[Droid Incredible Android Development] setexascustoms:
Here's what I got, typical day for me. All the device info's in my sig.
[Droid Incredible Android Development] lowkey9:
I've also noticed improved battery life when the phone is idle. I was at 50% earlier (didn't use the phone for much besides music while at the gym for two hours on tuesday night) while unplugged for almost 48 hours. Charging times have also been improved by about 300%, like others have said, about 1% per minute on AC.
[Droid Incredible Android Development] gmichaelow:
Yeah, the %s don't seem to change when the phone stays idle. From what I can tell it takes around 5 minutes of "active" use for the % to actually change.
[Droid Incredible Android Development] Nom Prophet:
I got my charge back! And idle is way better. 100% batt at midnight. 89% when I wake up at 8. No offense to King's kernels, but this is charging at least 3 times faster than BFS #1 while I've noticed no difference in performance.

Thank you!

Skyraider Sense 3.3.2
[Droid Incredible Android Development] xShin:
Hmm.. no I have not actually. How exactly do I do that, and do you think it would help? Again, I'm really not sure if its a random battery drain issue or just an inaccurate reporting issue.. my battery seems to be a tank when the phone's sleeping, it just destroys battery in the few minutes after I wake it up lol.
[Droid Incredible Android Development] jbdan:
This is how I do other fellows might have different methods. First bump charge your phone while phone is off. Boot into recovery (volume button down and press power button, hold till splash comes up) and go to "advanced"

From there "wipe battery stats"

Give it a day and see how it fairs

It doesn't help battery life just reports more accurately.

Try it :)
[Droid Incredible Android Development] marcmarshall:
I am getting the best battery life of any kernel I have tried with this. The charging time is also much faster. I lost about 100 points in Quadrant score (about 1100) and I do get periodic lags. I am happy with the trade off.
[Droid Incredible Android Development] xShin:
Sure, I'll give it a try tomorrow morning :P
[Droid Incredible Android Development] jprow507:
WOW! I just installed this kernel and haven't used my phone for about an hour and 15 minutes to see what battery life would be like .... in that time period of inactivity the battery level has not gone down a single percentage and would normally have dropped from 5-7 percent.
[Droid Incredible Android Development] Bakadeshi:
I've also noticed much faster charge times and better sleep efficiency. I have not noticed any real change in realworld performance between this and skyraider 3.3 default kernel. Battery drain seems to be about the same during actual use aswell. The real benefits to this kernel seems to be just charge time and less drain during sleep .
[Droid Incredible Android Development] billybob275:
I'm really liking this Kernel. Has there been any news regarding the source of this being leaked, or possibly any progress being made with setCPU being compatible with this?
[Droid Incredible Android Development] jasonb1985:
this is what i'm waiting for. this kernel undervolted with a conservative governor with screen a off profile sounds like the way to go. come one HTC, release the codez!!
[Droid Incredible Android Development] chagersc:
did the source for the latest incredible update released today (you can find it on droidlife) include this kernel?
[Droid Incredible Android Development] rmk40:
Nope, no new kernel source yet.
[Droid Incredible Android Development] King Speedy:
For anyone interested, the latest update to SetCPU (2.0.4) now disables perflock on this kernel.
[Droid Incredible Android Development] WoZZeR999:
Latest SetCPU update fixes the disable PerfLock on this kernel.
[Droid Incredible Android Development] Lexus One:
2.6.32.24 ?

Whats the story on this latest base kernal? Ziggy and King have already used it. But I'm looking for a stock version. Be nice if it had the Perflock disable feature. :)
[Droid Incredible Android Development] Hand76:
Woah yea you guys beat me to it I was just about to post about the update to SetCPU, didn't think it was going to work but bam! It Worked!

Now to set my screen off profiles. :D

BTW whats better for battery out of userspace or ondemand?
[Droid Incredible Android Development] jprow507:
This kernel already seems to be excellent at power usage when the screen is off and phone is idle. Would a SetCPU screen off profile even offer that much of a benefit?
[Droid Incredible Android Development] WoZZeR999:
At least we know you know how to read...

More for if you want to underclock the phone I guess. I'm testing it out with a screen off profile, so I can report back when I have a better idea of if it helps.
[Droid Incredible Android Development] DizkoDan:
Look at his post title. He was asking about a new kernel, not this one.
[Droid Incredible Android Development] WoZZeR999:
This is the latest 'stock' kernel. I believe the .24 is taken from kernel changelogs from other kernels.
[Droid Incredible Android Development] jasonb1985:
can we run a conservative governor on this kernel? or is on-demand the only option?
[Droid Incredible Android Development] Divine_Madcat:
Looks like its only ondemand right now.. bummer
[Droid Incredible Android Development] spjoneser:
Yeah bummer no conservative. This has seemed to make big difference in older kernels. I was excited to be able to at least set a screen off profile again. I've been using this kernel with Virtuous 3.1 and have seen not as good battery life as with Virtuous 3.0.1 and Adrynalynes custom kernel. But the charging time is AMAZING.

Anyways gonna try my screen off profile and see if it gets better, seemed that I was seeing faster drain with screen off. And I'm pretty sure nothing is draining it that shouldn't be. My awake time is correct.
[Droid Incredible Android Development] winston856:
So what govenor are you guys using with setCPU? On-demand? Anybody know what the userspace govenor does?
[Droid Incredible Android Development] King Speedy:
http://www.pokedev.com/setcpu/#7
[Droid Incredible Android Development] marcmarshall:
I too am loving this kernel. Battery life is so much improved I am not missing setcpu a bit.
[Droid Incredible Android Development] KKellett:
Still no word on the source being released for this kernel?
