SBC or No SBC build?

Have you tried a nohavs build, or even a build with nohavs and no undervolting at all to see if perhaps it's simply that your particular phone doesn't like undervolting? (Some phones are rather picky about undervolting)
[EVO 4G Android Development] squick:
Hey Net, I wrote you yesterday about an issue with the SBC kernels messing up the camera and/or sd card.

After finally switching the kernel to the 4.2.2 and trying an old sd card out of an old phone that definitely worked, I've come to the conclusion that something with the SBC part of the kernels fried my memory card. When I tried the camera with 4.2.2 installed and the old card, it is working again.

I just feel that you should be aware of this and maybe you might be able to aid in trying to fix it. I think others should be made aware of these kernels possibly frying the sd card.

Also, for some reason, it only affected the the picture part of the sd. I could put downloaded files on the card and flash just fine. Music that I synced from the computer were there. If you figure out why this could be happening I would like to know. Or if you have any insight.
[EVO 4G Android Development] squick:
Also I'm using Myn's, on 3.30, it was 4.3-havs-more-SBC, I believe cfs but already deleated from computer so I cant remember exactly.
[EVO 4G Android Development] squick:
Hey Net, I owe yo a huge APOLOGY. I had a thought that when this problem first happened on my wifes phone it was on SBC for Netarchy's CFS More Aggressive 4.2.1 from that other thread. My phone was on it as well but I only took pics once and checked them once. The problem is that you could take pics and connect to the computer as a disk drive one time and then the card is fried. If you try to connect after that to view any new pics, they're not there. I just put your 4.3 in withe the SBC and it worked with a brand new card.
[EVO 4G Android Development] NSIDIUS:
I'm definitely having some problems with the SBC Kernels...

Each one I try, the phone will charge for one second, then won't charge anymore. My battery meter goes through one cycle, and then the light goes off.

Running Fresh 3.5.0.1, Riptide9 Theme.

I can't download from the Stable or Smartass links on the first page... Something going on with the links.

Have to go find the stock Kernel again...
[EVO 4G Android Development] gingson:
No SBC build. Its the Net-Toast build. MikFroyo 4.2 seems pretty fast already with the kernel that came with it. I'll try the no-undervolting. Thanks.
[EVO 4G Android Development] cctaylor410:
Please for the sake of your battery do not drain your battery to 0mv. Lithium ion batteries are not safe to charge if drained below 2700mv. Once the the battery is at 3000mv there is basically no power left so a cut off is put in place above this voltage... for our phone around 3500mv. Lithium ion battery nominal voltage is 3.7v and fully charged is 4200mv. Most of capacity stored in the battery is between 3000mv and 4200mv. The the voltage begins to drop exponentially below 3200mv since more than 90% of the capacity is above this voltage. This cut off provides a safety margin to prevent over discharge which could result in a lithium paper weight. Hopefully this all makes sense if not ill jump on my comp and actually type something up cause I don't feel like writing a book on my evo :)

Although this does present a good opportunity for a question for the devs... can our hardware opporate with less than 3.5volts? If so I think the cutoff for our phones could be lowered to 3-3.2 volts and provide a marginal increase in battery life but may degrade cycles. I do not know enough about kernals to change this myself but I would be happy to test it out. But like I said there may be a hardware limitation.
[EVO 4G Android Development] xHausx:
It's been awhile since I researched it but I'm pretty sure the phone/hardware wont even recognize the battery if it gets to that point. There is also circuitry inside the battery that will self destruct and prevent damage to the battery if the voltages get too out of whack.
[EVO 4G Android Development] dkdude36:
ok, thanks for your response. a few people have told me this by now. i guess i am just having bad battery life and i need to fix it...
[EVO 4G Android Development] ejc1214:
I have an issue with the camera. When I take pictures they seem to be on a dark side and have a strange soft brownish hue to them. My wife is running Sprint official OS and hers look good. I am running netarchy-toastmod-4.3-bfs-havs-less-sbc-universal (Less Aggressive Undervolting). Anyone else have any such issues?
[EVO 4G Android Development] MikeOD:
I must be one of the luckiest people with an Evo.

I've had it since release day, it's a 0002 revision nova panel, shows 3 points of multitouch in dotty. I flashed in the new 4.3 kernel last night, CFS, HAVS, more agressive undervolting and SBC.

I've always been able to overclock to 1152 mhz without ANY stability issues at all, (it won't go any faster, it will get very sketchy very fast), I have absolutely no graphical/tearing issues at all, the phone scores 38 mflops in Linpack, and tends to run anywhere from 1390 to 1480 in Quadrant, it's been off the charger for 13 hours now, and is showing 54% of the battery left.

I'd been running the MS SBC kernel, but was happy to see I could go back to a Netarchy build using his charging trick. I installed the cpu widget last night right before I put the phone on the charger, and when I unplugged it this morning, I looked through it's log and noted that it spent a couple hours charging a tiny bit (like 4 to 5) and then spent the remainder of the night going between 0 and 1, back and forth.

I unplugged it and used it normally all day, actually maybe a little more than a typical day, my cousin needed an internet connection on his laptop for 10 minutes, so I gave him a hotspot, I used the GPS a couple times which I don't usually do because I was trying to find a restaurant, my uncle was trying to figure out the name of a song based on some lyrics he remembered, so after I found it in google I played it off youtube for him to see if it was the right song...did quite a bit of web browsing, and did the normal facebook/sms/gmail use that I always do every day.

I dunno...I guess I just find it funny, I never have any of the problems others seem to report, and I have awesome battery life with this thing at this point...stock though, it certainly did suck...when I first got the phone, I used to keep my old touch pro 2 battery with me (same battery just not red) so that I could swap it in when the phone would die by 3 in the afternoon...now I can make it until I go to bed with no worries of it dieing, and just plug it in again and let it charge while I sleep.

I've expirimented with a few different roms while I've had the phone...I really liked Calkulin's stuff, but got force close from the SMS app a lot, so I went with the Netarchy Burnt Droid rom (after having such great luck with your kernels)...and I haven't had a single problem with the phone since...everything is fast and responsive, nothing ever has stability problems, everything works (4G, both cameras, everything) and like I said, the battery seems to last as long as a regular old flip phone, nevermind a smartphone...thanks dude, you're a great developer.

Using the same kernal, np with kernal, using virus airborne 5.3
[EVO 4G Android Development] cctaylor410:
That's what I figured. The way they set up the stock batteries and voltages help ensure more battery cycles but less life per charge.

[EVO 4G Android Development] Sypris:
I like this. If only I had read it before I decided to run the SBC 4.3 kernel.

My phone turned off and wouldn't turn back on, or charge 5 minutes after the ball dropped in NYC and now it wont hold a charge. I used to lose between 3 - 5% charge over the course of 8 hours while I was sleeping. Now it goes from 60% to 20% in 7 hours.

I was running the netarchy-toastmod-4.3-cfs-havs-more-sbc-universal kernel.

And to Sprint we go for a replacement battery. :P
[EVO 4G Android Development] mildlydisturbed:
Playing with the netarchy-toastmod-4.3-bfs-havs-more-sbc-universal kernel.

HW 003, Sprint Lover's 12/31 ROM, Ultimatejuice, Seido innocell extended battery.

I think today is day 2 of the kernel being on my phone, I got it very shortly after it was up for download.

Woke up about 4, phone off the charger at 4:30, it's 12:30 now, 8% of the battery has been drained. That's 8 hours, 3 short phone calls, 8 texts, 1 app download of flightview followed by punching in info. I must say, I am mighty impressed. Theoretical 100 hour phone...

Even last night when I was playing pretty hard with it we were looking at between 3 & 5% drain an hour.

spiffy

SBC: it's all fun and games until someone loses an ear!
[EVO 4G Android Development] ageesm:
Odd

Is there any conceivable reason that 4.3 with SBC works fine yet 4.3 without SBC has clipping etc.

This goes against all logic as the battery charging is the only difference. On the More Havs aggressive UV version.
[EVO 4G Android Development] nuggyunlimited:
Is it ok to use setcpu with 4.3 cfs havs more or less sbc? Or are these kernels like smartass where setcpu is not needed?
[EVO 4G Android Development] xHausx:
Sounds about right. Some here like to think everything is fear mongering though lol :rolleyes:

Guess that's why some of us still have fully functional 002 evos from launch while others have wiped their RSA keys a few times and been through a half dozen phones.
[EVO 4G Android Development] thebeast614:
ok idk what was going on with the 4.2.1 and 4.2.2 builds cus they just wouldn't play nice...but after flashing 4.3, its just fantastic with my phone...and MS's SBC is a great touch too...net youre doing a great job
[EVO 4G Android Development] dkdude36:
+1 i would love to kno this.
[EVO 4G Android Development] xlGmanlx:
from my understanding not needed however NETARCHY has switched the default from smartass to conservative because of its not as good in usage battery drain
[EVO 4G Android Development] gpz1100:
frifox , why is your temp constant the whole time? Are you in a relatively hot environment?

The way I understand it, the battery widget takes a snapshot every x amount of seconds. The snapshot records the parameters you posted. Unless you have a very high sampling rate, the mA doesn't mean a whole lot, other than what was being consumed the instant the image was taken.

Under steady state conditions (phone sleeping, no emails coming in, no other updates), a series of samples, even at 60 sec. apart does draw a clearer picture, but such is not often the case. Lets say 5 seconds before the snapshot an email arrived, so the current consumed will be higher then, but by the time the batt widget recorded its parameters, current fell to a lower amount.

If i'm wrong in my understanding, those more familiar please explain further.
[EVO 4G Android Development] frifox:
Not really, just your average room temperature... I was watching movies just before putting it down so thats probably why first reading was high. Seems like that reading got "stuck" there till 8AM and have no idea why it did that. I have Tasker profile that shuts off all sound mindight to 8AM so maybe thats what triggered the widget to update the reading... But after doing that, the reading got stuck on the new value again =S

PS: im thinking of just attaching a physical amp meter between battery/phone and use those readings for battery consumption readings. This widget is quite unreliable
[EVO 4G Android Development] netarchy:
Are you running the latest radio updates/PRI etc?

Have you checked to see if you're getting some abnormally high awake times on the phone?

I've heard several people report that the latest PRI contributes to some nasty battery drain (which I've managed to duplicate), and reverting to PRI 1.77 and NV 1.77 takes care of that.

Alternatively, you could try flipping over to the nosbc kernel, or goin back to the stable build.
[EVO 4G Android Development] netarchy:
First post has been updated with a notice about the possible problems with battery life PRI 1.90 can present.
[EVO 4G Android Development] gpz1100:
Net, do you know under what conditions these high battery drains manifest?

Where can the older version nv and pri be found?

Thanks!
[EVO 4G Android Development] njfoses:
Running pri 1.90 on a 3.30 based rom will cause drain. Others have reported a drain even on a 3.70 rom with no real rhyme or reason. Get all versions here http://xdaforums.com/showthread.php?t=715485

I have a variant of wakelock going on.

I'm using k9 mail with imap. Anytime it receives mail when screen is off, it doesn't go back to sleep right away. Stays on for at least a minute. I thought it was a bug with the software, but the last few posts may suggest it's something else.

is there anything in the kernel that affects radios? i'm doing some power reading with an external ammeter and am wondering whether i should switch airplane mode or not when comparing different kernel's power suckage... just trying to eliminate unnecessary variables that would affect the readings ;)

i believe they are 100% separate
[EVO 4G Android Development] Brandito:
just curious, anyone have trouble with their 4g radio shutting off right away when enabled with this kernel?

i doubt it's the kernel but i haven't really done much to my phone so i don't have many things to narrow it down to.

seems like my phone can't get the mac address for wimax. restored to the stock kernel and the mac address shows up in about phone. shows unavailable with this kernel.

only other things i've flashed was ms's kernel and calkulins mms compression mod and his 4in1 boot menu. also flashed a stock 32 kernel, found that on the evo wiki.
[EVO 4G Android Development] gpz1100:
Flashed to pri 1.77, ran some tests to see if fixed the above bug. No affect on awake time, with push email, awake time=almost uptime... So looks like this issue isn't affecting me.. (Using Calkulin's 1.7.5 ROM before and after).
[EVO 4G Android Development] netarchy:
Are you using the latest radio updates? I encountered another person who had the same issue. Their radios were outdated. The problem went away after updating radios.

Which build(s) of toastmod did you notice this happening in?
[EVO 4G Android Development] netarchy:
That one actually sounds like it could be an app issue to be honest.
[EVO 4G Android Development] gpz1100:
Net, agreed. It's a really nice piece of software too, but this type of behavior really kills the battery when i'm getting email after email throughout the day. I already have a ticket open on the k9 bugsite, so we'll see what they come up with.

I am correct in expecting the software to return the phone to sleep mode right after receiving the message, not stall for a min, then, if no more messages, go to sleep. I mean, it's coming out of sleep to receive the message via imap, so why not go back just as quickly..
[EVO 4G Android Development] Brandito:
i've never flashed a radio on this phone, it's basically stock sense with your cfs havs more nosbc 4.3 kernel.

I am one of the few people that actually uses 5 point multi touch. Unfortunately, after flashing 4.3 cfs, havs, less, nosbc I have 2 instead of the 5 points I have had with all previous netarchy kernels. Is this a problem peculiar to me, or is the 5 point multi touch missing in this kernel? Other than that this kernel is working great for me.

I figure I will try this one for awhile and see how it goes. Its really snappy going through screens and everything. I was mainly looking for louder volume, and I really dont see much difference in it.

As far as sbc, I see mixed results.........
[EVO 4G Android Development] gpz1100:
I had ziggy 1/2 kernel (part of evio 1.76(a)) for half a day. I immediately noticed the difference in volume. In fact, there's a comment on ziggy's site about forgetting to add that into the latest one.

I flashed to net's 4.3 nosbc more havs cfs, and the volume returned.

The difference is is roughly 1-2 steps higher. That is, volume before at max is equal to volume now - 1-2 steps. Depending who's on the other end, it might even distort slightly, so I keep it down one notch.

If you're trying to test well, you need to call the same #. Calling your VM to listen to the greeting/intro is a good way. It keeps the caller on the other end somewhat constant.
