Well, I'm trying the Classic kernel, my first time using an SBC kernel. Can someone kinda run down the tips and tricks of using an SBC kernel? How long to charge, what not to do while charging, etc. The reason I'm wondering is because I have my phone on the charger a lot and I use it while it's charging...also, I plug my phone in while I sleep, but I only get about 4 hours of sleep every night. Because of these things, I'm not sure if SBC is the way to go for me.

Any thoughts?
[EVO 4G Original Development] volk9029:
The reason to use sbc is to fully charge the battery, especially if you have extended one. When you use the phone while it is trickle charging the sbc may stop working. Then you can reboot the phone to get it back to work. Other than that the kernel performs as all kernels do. So you can use your phone as usual.

[EVO 4G Original Development] moseso:
As I get it, the purpose of SBC is to charge the battery better than the stock charging system -- which charges the battery to "just" 100%, then, if left on the charger, let's it drain a bit, then charges some more. SBC Ramps it up to 100%, gradually reducing the charging rate until at 100% it continues to apply +4 to +6 mA. The result is, when you take the phone off the charger, in the morning, it's REALLY charged up. Without SBC, the bat meter will often drop to 95%, or so, within the first 10 minutes of use. With SBC, it will often remain at 100% for the first 30, or so, minutes of use.

So... It might mean that you can get through the day without needing to use it on-the-charger so much.

Since it trickle charges the battery, the potential for over-charging does exist. But lots of people have been using it for overnight charging for a year or more.

It's possible that my original battery gave up before a year was out due to SBC -- or that might not be the cause. I certainly get longer use in a day due to using it. And, if your battery goes south a little sooner, that's not such a big deal when you can find a pair of 1700 mh bats and a charger on eBay for about $20 - $25.
[EVO 4G Original Development] Guitarified:
So, using the phone while it is trickle charging can cause SBC to shut off...meaning using the phone after the green light has come on? How long do I charge after the green light comes on? Is my 4 hours of sleep enough uninterrupted charge time?
[EVO 4G Original Development] Guitarified:
Oh, and should I calibrate the battery? If yes, when?
[EVO 4G Original Development] cdadams1223:
I'd like to know this as well. Also, I flashed the kernel on page one with the SBC. There's only four governors listed. Can I set a screen off profile with an SBC kernel?
[EVO 4G Original Development] volk9029:
You did not mention how big is your battery. I think 4 hours should be enough for the regular battery. I keep my extended 7 to 8 hours on charger. Also i read on themikmik.com that wiping battery stats don't do anything to your battery longevity. So for a month or so i don't wipe battery stats.

Sent from my lair.
[EVO 4G Original Development] volk9029:
I am using underworld not classic. Underworld has 6 governors. As to the screen off profile it depends on the rom. Some have script built in. When you set profile for screen off and your rom may have different screen off profile, they will fight each other, so to say, and instead of saving battery you will loose more juice.

I'm extremely happy with this kernel. So much I posted I'm the wrong thread LOL. I'm getting incredible battery life on this sbc version. I'm curious if I could make it 2 full days. Great work on this! I could only get this life on miui using LEE kernel. Thanks for finally getting sbc to sense!

Running Mikg 3.1.1 with pneuma's ics theme.
[EVO 4G Original Development] life:
Awesome work on this kernel, i'm getting incredible battery life out of a sense rom.

as of right now im at 23 hours, 24 minutes on a single charge and still at 79% battery life. With that being said, i do want to stress, that my display time is only 22 minutes.

but with a sense rom, that is still amazing. With stock or even some other custom kernels available, i was getting maybe 24 hours at the most with same kinda display time and be at like 15% battery. i only use my phone to text, call, and check these forums, so my use is always light. But with this kinda of battery life i might move some of the games from my tablet to my phone to enjoy everywhere.....

Thank you for the work, it is very much appreciated.

So, I'm thinking that, for some reason, the SBC kernel is not for me. I powered off and plugged my phone at around 2am. At 10:08am, I unplugged, turned the phone on, and by the time everything was up and running, I was at 95% battery. Made two quick phone calls and had a bunch of texts and a voicemail come in, and right now, at 10:23am, I'm sitting at 90%. That doesn't seem quite right, does it? Oh, and it's a standard battery...the one that came with the phone.

Thoughts?
[EVO 4G Original Development] volk9029:
Download battery monitor widget from the market. Don't turn off your phone. Once your battery reached 100% look at the widget. Sbc kernel will still give you positive charge. It might be 5,6 mah but it has to be positive. Set you widget to show voltage.

I just had my first bootloop on classic kernel. It happened when I ended a call. Did a full boot loop.

I had just used the camera to take two pictures, sent them via email, and made a call once sent.
[EVO 4G Original Development] mutepoint:
Over 48hrs on the Classic-SBC and no bootloops. Came off the charger this morning with 4228mv... Stays on 100% forever... Don't think the bootloop issue I got on Underworld was related to SBC - more likely smartass v2 govenor.

Color me extremely satisfied!!!

Edit: I forgot to mention I'm running a senseless version of Tommy's v006 Classic. I use ADWex, Fancy Widgets, CalPad Pro, and Moogly for notes.

[EVO 4G Original Development] NxNW:
Nydgeo - thank you for a very informative post. This entire conversation had been very enlightening. And of course we need to thank ca1ne for prompting the conversation in the first place.

I just want to say if anyone has ever been killed due to an exploding battery, I doubt it was a cellphone battery (being trickle charged by a custom kernel) that did it. If there's a reference you can cite to back up that claim I'd love to see it.

My overall take on this whole thing is:

- SBC is a nice-to-have, it does work, and the downsides are negligible.

- all reports of real world battery usage are anecdotal and can only be treated as one data point in a larger picture

- making a change to your battery situation and breathlessly reporting the results 30 minutes after taking it off the charger for the first time is too soon. You really need to go through a couple reasonably long or deep discharge cycles before trying to draw too many conclusions about the effects of the changes you have made.

Just my 2 cents ..
[EVO 4G Original Development] Guitarified:
I appreciate all the help and info about SBC. I just tried the steps in the above post but mine never got to a rate of 2 - 6mA. After the green light came on, it hovered around the 20's and 30's, hitting 18 once and then the next time I looked, minutes later, it was negative. Of course, this was not an overnight charging so texts were coming in and I had to respond to a few...I assume that's the problem. I'll leave it on when charging tonight and won't touch it until the next morning and see what happens.

What is "10 point touch"?
[EVO 4G Original Development] moseso:
Don't know what you mean by a "dumb charge," but, it looks as though the SBC is doing what it should. Every battery is a little different. It looks like that's where your battery tops-out. How old is it? That may have an effect.
[EVO 4G Original Development] alaman68:
Dumb charging is a phone off calibration. My voltage is significantly lower than other SBC kernels I use. It will usually top off at 4218 but I can't seem to get above 4195 here and battery level is instantly dropping. I know the SBC is trickle charging, I am just having skewed results that need to be corrected by upping the voltages somehow, if that is possible.

I have gotten a few reports of bootloops on classic, I expected bugs in underworld, so I want to focus on figuring out what's up with classic...., to try to nail it down, I need to know what ROM, if tweaks installed, what were you doing at the time, and if anyone has logs... Trying to replicate the bootloops, I personally haven't gotten any yet... So I want to try to force one while I have adb hooked up...

Luckily with boot manager, I can setup your environment in a slot...

I will boost the audio more when I update hopefully to patch any bugs...

Also 10 point touch really is just multtitouch... There us a check because depending on your hardware it will reduce to 2..

Running Tommy's rom with no issues. My phone has never done the best on stock kernels but the charging is working as it should and I've not had any bootloops/restarts. On my 3rd or 4th day.

Oh and I do have Smurf's script installed. Everything else is in my sig.

I was just reminded about one issue I have periodically. My data (mobile network and wifi) won't turn on automatically. Just happens once on a while. I turn it on manually and it works fine. Could that be a kernel problem?

I think I can safely say it's the smurf tweaks causing the reboots/lockups. I was having the lockups frequently until I unsmurfed. I just tried the 3G TurboCharger script and my data speeds are now in the toilet. I use MikG 3.11 as my daily driver. I can't say for certain, but it seems to me that these scripts conflict with existing ones cooked into the ROM.

I can't seem to get SBC to stick with this or the test version kernel. At night, I'll put the phone charging, it will charge to 100, then slowly the mA will drop to zero in the middle of the night, and then go negative and stay negative. I am on HW 003, SOS X ROM, and no other scripts/tweaks installed. My understanding is that it should not go negative, right? Any thoughts?

I have same problem, its our battery. When you get to 0 reboot recovery wipe caches, don't reboot power off. Then reboot. After you plug it back in you should see somewhere around 134mv in charge at 100%. If it doesn't drop after 5 mins or so you need a fresh battery
