Battery drain when idle is amazing! 75 > 68 after about 7 hours overnight.

I can't seem to get a reading of the battery drain during heavy usage. It's only been two days, but it seems like it drained faster. :confused:

But it seems like it charges faster?? :eek:

I dunno. The last two were just very informal observations. But there's no denying my first statement.
[Fascinate Android Development] crispybacon:
Wow good to know, for some reason i always thought it was the other way around. I'll start using wifi more when i'm at home.
[Fascinate Android Development] emarx429:
I thought the whole point of these kernels was interactive adjustment and streamlined for our processors and file systems...
[Fascinate Android Development] dmaustin:
I'm noticing faster battery drain as well. The only things I can think of that I'm doing different are that I turned min up to 200 in setcpu, and I'm also using interactive instead of conservative because I saw somewhere it was "fixed"previously. I have no idea how interactive is different from on demand? I just thought I'd throw that out there cuz I see a lot of people having similar issues and I don't think its the kernel. Going to try conservative with 200 min tomorrow.

I'm using JTs super clean with the super dark theme.

Does this kernel have the voodoo color fix? I keep my brightness at 100 since that came out.

My battery dropped from 15 to 8 while swyping this message!
[Fascinate Android Development] CHANGiism:
Great great kernel! Made my phone lag free! However, I have battery draining issue as well.

I checked spare parts and mine has stayed awake for 100%!

I have stock rom, flashed this kernel over the stock.. nothing has changed other than the kernel. No SetCpu.

Can someone check the spare parts on their phone and see how long the phone has stayed awake for? Thanks.

To add to that... It stayed awake 100% since the last boot, which was when I rebooted after flashing. Wake usage is all by Android System.
[Fascinate Android Development] crispybacon:
They do, you just cant overclock the kernel past 1ghz. Like you can with some Voodoo kernels. Other than not overclocking these kernels work great for everything else.
[Fascinate Android Development] ryanf:
I to have noticed that with setcpu at 200 it drains really fast. I just changed back to 100 and am good again. I didnt have the audio cracking I just thought that it would download and wake up faster on 200
[Fascinate Android Development] crispybacon:
Even when i had a kernel with the Voodoo color-fix i didn't really notice it at 100%. So i went back to 25% and my battery life is great.
[Fascinate Android Development] CHANGiism:
This kernel does not have voodoo color fix I believe so you should turn your brightness down. Besides, if you can't tell if you have voodoo color fix or not, what's the point?
[Fascinate Android Development] thefunkbot:
Because of the battery drain i've flashed back to 1.0.36 and left everything else the same. later i will let you know if my battery is doing any better.

My phone is running JT's super clean ROM with no setcpu
[Fascinate Android Development] dmaustin:
I did like the voodoo color fix, and seemed to notice the tint is a little more yellow now. Did the color fix help battery life on 100% that much? I did notice that about 80% of usage was from the screen.

I'll make some changes and see what happens tomorrow. Anyway, big thanks to geeknik for the snappiest fascinate kernel so far!
[Fascinate Android Development] crispybacon:
The only thing i can really say i've found as an issue so far with v1.2.3 is sometimes 3g goes out, when i know i'm in a 3g area. But all i do is just do a reboot and it's fine again.
[Fascinate Android Development] ryanf:
Try turning on airplane mode and shutting it off again. That should reset your 3g
[Fascinate Android Development] emarx429:
Re-trying this kernel after batt stat wipe from cwm... we'llc tomorrow morning if my battery stays anywhere near where I leave it tonight... Tried jt's 11/16 and 11/15 trest lv kernels just as bad battery drain on 16, with a wierd wifi issue on 15...
[Fascinate Android Development] chrisexv6:
Trying the same. Charged to 100% this AM, wiped battery stats and now trying to drain it way down before I re-try the kernel. I noticed this suggested in the Bionix ROM thread (Vibrant forum, but I suppose the battery recondition process could apply to any ROM/kernel). They actually said its required with one of their ROMs after its installed.

Something I noticed: on the earlier non-uv kernel, I would see the 3G icon go from up/down arrows to "3GD", I assumed that meant 3G disabled. Was that kernel disabling 3G when it was idle? That could explain a lot about power consumption differences.

I dont see that 3GD icon in the new UV kernel, but Im no longer on the stock theme either so I just dont know if the theme Im running is missing the icon, or if the new kernel really isnt disabling the 3G when its idle (if that was the intention of the last test non-uv kernel)
[Fascinate Android Development] crispybacon:
Thanks, I'll have to try that next time it does it.
[Fascinate Android Development] destroyerbmx:
I am happy to say that I don't have these issues, maybe just normal battery life, but I will wipe battery in the morning just to be sure.
[Fascinate Android Development] billypickett:
I keep getting E:signature verification failed when trying to flash this kertnel
[Fascinate Android Development] crispybacon:
Sounds like CWM Recovery wasn't installed properly, or you didn't flash after you installed it.
[Fascinate Android Development] billypickett:
So what do I need to do fappy jones
[Fascinate Android Development] crispybacon:
Did you use Odin to install CWM Recovery?

If you did, did you open ROM Manager and select Flash ClockworkMod Recovery?

It just sounds like something's not right with CWM Recovery on your phone.
[Fascinate Android Development] rise4310:
i'll try the battery recondition tomorrow as well. i've seen a significant increase in battery drain.

1.2.3 and jt super clean
[Fascinate Android Development] crispybacon:
Yeah my i saw alot of battery drain too, i went back to 1.0.36 for now. Almost debating on going back to a Dirrk D02-LV Voodoo kernel.
[Fascinate Android Development] Adr0it:
I've had great battery life. I can easily get 2 days out of it with moderate use, minimum clock speed at 200 MHz in SetCPU. I listen to music walking to/from classes, usually some browsing in class if I want to pull up a file or email my professor is referencing (or I'm just bored), some decent texting throughout the evening/night (but not a social animal), and receiving email all day.

The only time I really kill my battery is when I decide to flash stuff and reboot my phone all day in class.
[Fascinate Android Development] TheBadBen:
This happened to me yesterday and it looked to me like my SD card had come loose somehow. I had just fine a battery pull so it may have been something I did rather than a phone problem, butt once I just pushed in the card everything worked fine. Have you been able to get into CWM before?
[Fascinate Android Development] Njzkrish:
thank you for all the effort you put into doing this for us. I like the kernels, only problem for me on this one is the battery drain. Went from 2am at 66% to 41% at 8am while the phone was on standby and still dropping. Switched back to .36 to see if it fixes that.
[Fascinate Android Development] chrisexv6:
Please report back. Im thinking of doing the same but was worried the battery drain would still be bad there too. Im wondering if its an app or something I have running (although on the non-UV kernel I dont remember having this issue)

Mine isnt dropping as fast as yours though....its looking to be about 1.25 to 1.5%/hr
[Fascinate Android Development] thefunkbot:
Okay it is definitely this kernel causing the battery drain. Or a combination of things with this kernel.

Last night i flashed back to 1.0.36 and my battery drained by only 7% overnight, when it drained 30% while i had 1.2.3.
[Fascinate Android Development] ryanf:
I also had this happen. I had neen cleaning out my sd card the night before and must have deleted something. I just flashed cwm recovery from rom man, took care of it for me.
[Fascinate Android Development] cckeeler:
I am also getting the battery drain issue. Does someone have a link to the 1.0.36? I tried the original link on the post on this forum but it doesn't appear to be a valid link anymore.
[Fascinate Android Development] tlogank:
http://db.tt/XdmyO36
[Fascinate Android Development] cckeeler:
That link is still no good. I get an error "webpage not available."
[Fascinate Android Development] emarx429:
Woke up this am to c a 1-2% loss over night, which sounds good to me... Clearly something with the batt stats...either way I'm glad its not killing my phone in the middle of the night anymore...
[Fascinate Android Development] Toastercookie:
I can confirm that one probable reason for the battery drain issue is that the device isn't going to sleep. I flashed this kernel and while its screaming fast, spare parts indeed says that the phone never goes to sleep.

Other people having this issue, do you mind checking and seeing if that's the case for you as well? DL Spare Parts from Market if you haven't already, go to "Battery History" and select "Other Usage" from the first drop-down.

If "Running" is at 100%, that means your phone isn't sleeping.

"Partial Wake Usage" is entirely "Android System," so it seems like something in this kernel is definitely the issue.
[Fascinate Android Development] chrisexv6:
Is that 1 to 2% per hour, or 1 to 2% total loss?

1 to 2% per hour is what Im seeing
[Fascinate Android Development] CHANGiism:
That's the exact same issue that I had when I flashed this kernel. What's more interesting is that if you reboot the phone, then the phone will operate normally and will go to sleep normally, UNTIL you charge your phone. After you charge your phone, your phone will not go to sleep anymore. WTH? Don't know. Experiment and see if you can replicate what I've experienced.
[Fascinate Android Development] Toastercookie:
Nailed it! Restarting the phone fixes the sleep bug until you plug the phone in again.

This will be a workable solution until a fix comes out. I usually only charge at night so a quick reboot in the morning isn't the end of the world.
[Fascinate Android Development] plvaulter06:
ya, the download link appears to be broken for me too
[Fascinate Android Development] CHANGiism:
Cool, I'm glad I'm not the only one having the same issue. I feel good narrowing down the bug and find what's causing it and what fixes it! Hopefully geek will find the root cause of this issue and roll out an update.
[Fascinate Android Development] wowser21:
Quick question. Can the kernel affect the phone's reception? One of the offices i work at a couple times a week i get almost no 3G signal, but i usually get 2-3bars in the 1x mode. This is the first time i'm back at this office since flashing to this kernel and i get no bars whatsoever and every call i try to make either doesn't go through or gets dropped. I flashed back to the stable version of the kernel and i see the same problem.

I'm just trying to figure out if it could be caused by the kernel or something else is going on. I've never had a dropped call or 0 bars before at this location.

thanks.

Just to note, i haven't noticed a difference in reception in other areas that i frequent, but just wanted to confirm.
[Fascinate Android Development] johnnyv5:
5 hours of moderate (3 phone calls, about 20 to 30 pushed emails, google talk, and about 30 minutes of browsing web) use w/ 52% available. Going to check tomorrow with the 1.0.36 kernel tomorrow.

jv

edit: 7hours 17 minutes and down to 15% using 1.2.3 kernel.... Going to flash 1.0.36 and see if it is any better.

Update: 1.0.36 after 5 hours almost same thing w/ 1.2.3. Next test is going to be 1.2.3 w/ setcpu at 200 min 1000 max...
[Fascinate Android Development] Not_So_There:
I have juice defender turn off my data for most of the night when I am sleeping. I noticed with this kernel that I lost more battery then normal during that time with it just sitting there (I have the plotter software installed as well).
[Fascinate Android Development] Mikem74:
In rom manager, whick kernal inder jt is the 1.0.36 kernel, they just have dates? Or if someone could repost the 1.0.36 that would be great...
[Fascinate Android Development] ibebyi:
Download THIS kernel and flash it using Clockwork Recovery.

JT's list only has kernels that jt has made. This kernel and 1.0.36 was made by geeknik
[Fascinate Android Development] Mikem74:
Thanks. I have the v1.2.3, but like others I'm having problem with battery drain and I didn't save the 1.0.36. If anyone has the 1.0.36... thanks.... also thanks for the info about the JT kernels

[Fascinate Android Development] noxqzs:
the original thread got bumped to the second page. there is a link in first post to file.

I just flashed 1.0.36 last night and left it to charge overnight. Since 8 this morning, I have made 7 phone calls, at about 25 minutes total. Used WiFi for 10 minutes transferring files the whole time, and 2 text messages. It is 6:45 now and I am at 80%.

Are the newer kernels the same with exception of lower voltage, or are there more changes?
[Fascinate Android Development] Mikem74:
Thanks...... thought it was removed
[Fascinate Android Development] grin0048:
I've had some pretty obvious battery drain and the audio popping as well. As others have said, the popping goes away as soon as the screen turns off. The most notable thing I'm seeing is that there will be a pop at each jump of the battery indicator when the phone is charging (using the circular battery meter). If the phone isn't charging, the pops will only occur if I'm interacting with the ui. This issue has been pretty consistent across each version of this kernel that I've tried and was also present for me in one of jt's versions of the last few days (he has been incorporating some of geeknik's work as of late, right?)

I appreciate the work of all the devs, the performance gains over stock are fantastic.
[Fascinate Android Development] Toastercookie:
For those of you who are complaining about popping, a solution to that has been found. Go to setcpu and make the minimum 200 mhz instead of 100. Fixes it instantly
[Fascinate Android Development] neyenlives:
i can turn the pop/static sound on and off like a switch by simply allowing the screen to lock.....so all i do is plug in my headphones, launch Pandora, hit the power button to lock the screen, and drop it back in my holster....done..no music pop/static unless i unlock the screen, and then it goes away instantly once i lock it again

i am running setCPU with 100Mhz min, 1000Mhz max by the way....no setting to 200Mhz min
[Fascinate Android Development] Daswolven:
Two days in, no issues.

No as in none.
[Fascinate Android Development] GoogleAndroid:
My battery life is garbage now. Is it because I am using the Interactive governor? Do I even need to use SetCPU? Otherwise, amazing kernel. The phone is unbelievably smooth, snappy, and fast. I'm so impressed. This is what happens when you optimize the kernel specifically for the CPU. Redraws are suddenly instant and things load twice as fast.
[Fascinate Android Development] iTz Nicholas72:
Anyone said earlier its because the phone is not locking when you hit the power button.

Checking the usage stats in Spare Parts it saya running 100% which is what is causing the poor life.

ROM: Blackhole 1.3

Kernel: StupidFast 1.2.3
[Fascinate Android Development] crispybacon:
You can set setCPU to 200Mhz. It goes 100,200,400,800,1000 in both min and max.
[Fascinate Android Development] devlp1213:
I'm not using set cpu and have awesome battery life I'm not having a single problem
[Fascinate Android Development] theraptscallion:
After three days with this kernel, I had to go back to a previous version. I had no issues with music, tested with the stock player and poweramp/pandora. My gps stayed the same (one minute on average for my first lock of the day). My battery usage did increase markedly if I did not reset shortly after unplugging from the charger as mentioned previously. My only unique bug was an inability to toggle gps from the pulldown. I could enable it through widgets and apps, but for some reason the uv kernel didn't like me using the pulldown. It works fine with all other stupidfast releases.

Running jts super clean if that helps anyone...
[Fascinate Android Development] crispybacon:
The only problems i've seen so far with either kernel was, battery life wasn't the best and it would drop 3g in area's that have 3g and go back to 1x. Doing airplane mode on/off every 5 minutes isn't that fun. Other than that the kernels are great.
[Fascinate Android Development] LX.SF:
Same issues for me; I had been previously running 1.1.4 which I believe has the same problem with battery. Rebooting does fix this temporarily. I just tested out the GPS toggle from the pulldown, I'm having the same issue. Occasionally the toggle will work, but the indicator will either not appear or not turn off when the GPS is on or off respectively. Using the same ROM also.
[Fascinate Android Development] Piercing Heavens:
My partial wake is all android system also.
[Fascinate Android Development] jamesbdh:
I am not having this issue. In fact this is the best kernel for battery life for me. On 12 hours and just now hit 15%. I am not having that"running" issue. Have this kernel and backhole 1.3 no set cpu. No audio issues either.
[Fascinate Android Development] draco259:
My battery life seems good. This charge has lasted about 24 hrs with with fairly high use, pandora, games txting internet and e-mail. I also have setcpu downloaded at at 200 min due to the sound problems.
[Fascinate Android Development] Piercing Heavens:
Rebooting the phone after unplugging it from the charger allowed my phone to go to sleep.
[Fascinate Android Development] absens:
I'm having the same issue as Heavens. Tried recalibrating the battery, also reset my phone. Flashed this kernel after a full wipe. Battery dropped 30%, with no apps running, the first night. Gonna see what happens if I reboot right before bed tonight. Love the speed of this kernel though.

Awesome kernel but I used it for 2 days and it killed battery. Went back to 1.0.3.6
[Fascinate Android Development] mindtrip1016:
I think we have far bigger issues than battery life, though i can not complain about that issue. Has anyone turned off their fascinate for any considerable amount of time? An hour? Overnight? I normally turn mine off over night and upon boot up, the screen freezes or goes blank. This happened a couple of days ago with the 1.2.2 uv kernel. I quickly got on the forum to see if there was a fix and saw the updated 1.2.3 kernel. I installed to sd card, booted in recovery and flashed the newer version with no problems. Last night i fell asleep listening to music, so didn't turn the phone off. Tonight however, i did and had the same problem with the phone freezing or showing a blank screen after media scanning was complete. I flashed a different rom to pinpoint the culprit, but ended up with the.same issue. I flashed the stock kernel and now it boots again. I'm just curious if anyone else has had the same boot up problem and knew of a way around it besides leaving the device on 24/7?
[Fascinate Android Development] thefunkbot:
i dont think there is any difference between having the phone off for a couple minutes or for a few hours.... off is off

but what do i know lol
[Fascinate Android Development] str8havoc:
Battery

It dosn't matter what kernel i use my battery drains fast. Is there anything I can to to change this. I have looked aroud tried different kernels and I get the same result.

When I go into the about phone to check the version its always the same thing 2.6.29. When I had my D1 the version would read what I installed. Is it different with the SF.
[Fascinate Android Development] itznfb:
Just wanted to report my results. I still have popping in all apps that have sound whether screen is locked or not. I'm not going to set the cpu to min 200 because that defeats the purpose of using the UV kernal.

I flashed from jt's latest stable kernal and went from 90% battery to 15% battery just during the 2min flash/reboot. Drained to 5% in a matter of minutes but has been sitting at 5% for 45 minutes now.

When I open calender and switch to month view, I try to select a future date for which I have nothing scheduled and instead of going to the day I selected, it goes to the last day have something scheduled. Does that make sense? Anyone else find this annoying ?

[HD7 General] robart76:
It depends whether you are in a day or agenda view (before accessing the month view). If you are in a day view it'll go to the selected day, if you are in agenda view it'll go to the next day with appointment which makes sense as days without appointments aren't displayed in agenda view.

Thanks for the tip, it does now make sense!

Another problem I have just found, after one month has passed calendar appointments disappear from handset calendar (not reoccuring ones) but remain OK on Windows Live Calendar on PC/in Outlook. This is a problem for me as I like to keep all my past appointments with me on the handset.

Does anyone else have the same problem?
