Is the trickle charging kernel working for you without any negative effects?

Hello,
I was just wondering how many people use trickle charging and what percentage of the people that use this kernel have had bad effects. Post a reply or vote on a poll.
Thanks
Edit: How did this get into the android development forum. I meant to put this in general. Please move it there.
Thanks

I've used it on the Stock & Extended battery without issue. msm####'s SBC-15 kernel.
Well over 2 months now.

I've used it on the stock battery for about 2-3months now with no noticeable side effects. Battery stays at 100% for a little while, instead of dropping 10% depending on where the battery was during it's on/off charge cycle with non SBC kernels.
Mod alert to have the thread moved. Triangle in the top right corner of your post.

Greatest kernel there is. Have used them for 3 months or more with stock and extended and have had no issues what so ever. Except for amazing battery life.

i use miui rom with the savage kernel sbc 1.6 and don't have any problem at all on extended battery or stock.

Never had a problem with these wonderful kernels.

I haven't had any problems. been running sz on cm7 since the beginning off and on. I'm on the teamwin HDMI kernel right now though

So far so good. I am using the latest SBC V7 right now on my 3500 extended battery. My Rom is myns rls1. I had 100% for a good 2hr and 10mins or so.

I am pretty sure the so called "problem" with SBC kernals is a result of people buying cheap crappy chinese batteries, having one or two die, and not wanting to be blamed for them buying crappy batteries blamed something else. "OH SBC DID IT!"
just my 2 cents since this has only happened with a few batteries from my understanding and they were all cheap chinese batteries.

100% for 2hours? How much use?

I have been using SBC since the day it went public. I use it on a stock battery and a cheap a$$ eBay battery. Never had a single problem, longest i have went was at 100% was around 7 hours (0 use of course).

I have been using SBC since it was public quite a while back. No problems except better battery life.

I didn't use my phone for the 2hrs after I took it off the charger. I think I can get 20+ hours with moderate use. I think this kernel is working for me.
Sent from my PC36100 using XDA App

Just switched like a week ago, I just take it off the charger before I fall asleep, don't want it on the charger for 7-9 hours. No issues yet. My battery was at 100% when I took it off the charger last night. I checked my Facebook & did a couple other things for about 20 mins and then turned wifi off & went to sleep. When I woke up 9 hours later it was still at 100%, and stayed that way for another 20 mins of use. Best battery life I've seen in a long time.

Been using SBC kernels for awhile now, on multiple roms, and experiencing AMAZING battery life. With zero problems twords stock and 3500 ma batteries. I run this kernel on my company phones that are rooted as well. on average over 10 devices at a time with 0 compaints to date.
Vaelpak went back to a crappy kernel on his new 3.2 and my battery life started sucking it up again. Flashed back to SBC for Netarchy's 4.1.9.1 Non-HAVS v7. Ive found that to be the best when it comes to draining.
Even under heavy use I still get a solid 12 hours of battery on my 3500. Thats running GPS, Wifi, wifi tether, lots of emails, texts, and other communications on a busy day. During slow times Ive gotten a single charge to last 57 hours of light usage. That was with wifi and bluetooth enabled the whole time and juice defender running as well.
I have since recently dropped juice defender, and only using SBC, and seeing ~ 30-35 hours before full drain on normal usage.

[Q] SBC kernels

Are SBC kernels really that dangerous? Theres some horror stories floating around about batteries that have nearly exploded and smoke literally coming out of the battery because the trickle charge causes the battery to overcharge, which apparently Li-ion batteries dont take very well to.
Has anyone on here had any problems? I usually charge my phone over night and its fairly close to my head, so i would prefer to not wake up to a loud pop and 3rd degreee chemical burns. But at the same time SBC kernels definitely give me more battery life, at least 10%. my phone stays between 100%-90% for a while rather than dropping right away.
I also have an extra battery, so im not too worried about the battery just losing its ability to accept a charge. I just dont want it to blow up in my face.

I haven't had any problems using it. As far as I know it was all just rumor and no proof or pics of it actually happening.

I did see one pic, which is why i believe it to some extent. The inside of the guys case looked like the battery had been letting off quite a bit of smoke. If trickle charge had absolutely no negative effect on the battery, im sure HTC would have implemented it in the first place. I dont think exploding should be a frequent problem, at least with htc batteries, because the battery itself has a small chip that should play a part in regulating charge. Maybe 3rd party batteries have something different that allow them to accept too much charge.

When the SBC kernels were first being discussed a few months back, there were several reports of battery exploding/catching on fire among other things, but I haven't read or heard anything of that nature in quite awhile and there have been quite a few SBC kernels introduced since that time and a lot of people use them.

They slapped my baby turtles

Myself and a friend with over 6 months of use and no issues to report. Both stock and cheap $10 extended batteries have been used.

Never had an issue using SBC kernal. My wife and I both use Netarches SBC kernal.

Have been using net's 4.1.9.1 sbc more havs since it came out....no problems great battery life...used it on myn's 2.2......warm z and finally on Koni's elite roms...which I have stayed with since they were introduced.....if you haven't tried Koni's....you probably should.....it is by far the best rom out there.....please see for yourself......you won't be disappointed.

I was nervous at first too about this whole SBC thing, then I decided to go for it and I haven't gone back. My battery is usually cooler then with a nonsbc and I get easily an extra hour of use with them.

Im using tiamat 3.3.8 sbc kernel and haven't had issues for three months. I kept a close eye on vitals with the battery monitor widget. Highest mV was 4219 and highest temp was 51 C (59 C in a hot car). No sign of smoking, plating, or degradation in performance.

Only thing I can say is that sbc will wear your battery down quicker in time due to it over charging lol but hell there only 10 bucks on ebay so what you have to lose lol.

It was like 8 evos out of like millions but since then there hasn't been much if any problems
Sent from my PC36100 using XDA App

Is it "more dangerous"? Probably. But to date I think there were 7 or 8 people with battery issues. I personally haven't had any SBC issues across many roms/kernels.

Those 8 people, or however many, had those problems in the earliest days of SBC development, for one thing.
Also, can those problems really be attributed to the SBC kernel? Or were they coincidentally just all using SBC.
It's like the white screen of Death. It started wit ha few perople on CM7, and the rumor was CM was frying their phones.....
Til it happened on every other setup, too.

anyone know if the sbc mod works while the phone is off

It does not, sbc only works when the phone is at 100% and on, all other times its using the stock charge setup

[Q] Poor battery life -- halp!

I recently got into rooting and flashing at the end of last year. This site has been a great resource for how to's and learning about the ins and outs of phone hacking.
Anyways, here's the background info: rooted using Unrevoked Forever, s-off, stayed with stock ROM and kernel only using SetCPU profiles. When I was on stock software, I had unbelievable battery life. I'm a light user (~10% awake time) and rarely beat on the battery -- light calling, email, texting, Facebook, random messing around etc. Anyways, when 3.70.651.1 came out, I knew that was my chance to flash my first ROM.
I flashed SprintLovers and got decent battery life, but nothing compared to when I was running the stock ROM. I then tried almost every variation of Netarchy's non-SBC's CFS 4.3.4 kernels -- more HAVS, less and no HAVS. No dice. I've tried with and without setCPU altogether, along with and without setCPU profiles but using the smartass and conservative governor. I always set the processor to 245-998 and never overclock.
I liked myn's Warm TwoPointTwo, so I recently tried that last week. Again, I'm getting okay battery life (~1.5 days) but with the usage I'm at I'm pretty sure I should be able to get 2 days easy. So I tried flashing Netarchy's 4.3.4 non-SBC CFS kernels with the same results. I've also tried with and without setCPU, along with and without setCPU profiles. Finally, I gave up and I'm currently using Netarchy's 4.2.1 cfs havs more smartass and using setCPU.
It's definitely not related to PRI 1.90 as I'm not getting the 100% partial wake time in Spare Parts, and I know the consensus is divided as to whether or not setCPU interferes with HAVS. I know all phones are different and ROMs and kernels interact differently on an individual basis, but I would really like to stick with myn's ROM and a good kernel to max my battery life. rather than go back to the stock ROM. Any suggestions on extending my battery life before I shamefully reflash back to stock software? I always do a full data/cache/dalvik before flashing a ROM, and wipe cache/dalvik before kernels.

Try recalibrating the battery. Charge to 100% and leave it on the charger a little longer. Then turn the phone off and boot into recovery. In recovery wipe battery stats - in Amon Ra it's under the wipe menu. Boot back up & use the phone normally until the battery drains completely, without charging the phone at all. Some people say until the phone turns off on its own, but I'd try to avoid that. Just get it as low as you can. Then once it's dead, charge it fully without breaking the charge until it's completely full. You should see an increase in life after that. There's also an app in the market that clears your battery stats. I believe it's called "Battery Calibration", but I could be wrong about the name.
Since you don't use your phone much you'd be a good candidate for undervolting. If you don't want to undervolt while the phone is in use, just use a screen off profile only. Turning radios off while you don't have a signal or you aren't using them will make a huge difference as well. Let us know how it goes

I've heard people recommending a battery calibration after flashing a new ROM. My battery has seemed to be jumping down a few %ages and then stabilizing for long periods of time at a single level. Perhaps this is what I'm missing. I'll give it a try tonight when I recharge and see if that helps. I may try undervolting, but seeing as I got great usage on the stock ROM with the same CPU range I'd like to stick with 248-998. I always have a screen off profile though (as noted in my first post). I've also heard about people shutting off radios and such but I don't think I'd want to take it to that extreme -- maybe if I get desperate enough to eek out that much juice I'll give it a shot.
Bonus: to alleviate my problems at home since I have terrible reception and I know that eats the battery, Sprint is shipping me an Airave free of charge! In the process of trying to contact Sprint's CS (*2 on the dialer), the phone was force closing *1 and *3 work fine, as does normally dialing so I guess the problem is only limited to *2 (I even rebooted and am too lazy to reflash just because I can't speed dial a number I rarely call). Hopefully with your suggestion, I can get back to insane battery life

Don't know if this will help you out at all, but here's my setup...
myn's Warm TwoPointTwo (RLS5)
Net's toastmod-4.3.4-cfs-havs-more-sbc
Launcher Pro Plus
SetCPU:
Screen Off: 128 max, 128 min conservative
Battery<101%: 499 max, 128 min conservative
MinFreeManager:
Set to Aggressive
Twitter, Flikr, and assorted useless (to me anyway) apps frozen with Titanium Backup
Unplugged at 0700 and as of 2205, my Seidio extended 3500 battery is STILL at 74%
Average usage day, with tons of emails, and SMS/MMS messages. About 2 hours of web surfing and 3 hours of Pandora, but not a lot of phone calls today though. About 7 hours spent on WiFi, the rest on 3G (No reliable/stable 4G near me yet).
Background data off
Auto-sync off
Enable always-on mobile data off
I have noticed this is the best battery kernel I have tried out of all of Netarchy's (ymmv). I've had this kernel for 2 weeks, and getting 2 days out of it with HEAVY usage is no problem. I only lost 4% of the battery from 2300 last night to 0700 this morning with the phone sitting on my nightstand.
It seemed to not last as long at first until I wiped battery data and started from scratch. Always a good idea to wipe battery data when swapping ROM's and kernels I notice. Also read (here, of course) that new kernels have a "break in" time of a few charging cycles until they settle in.
Overall:
Completely satisfied with this setup. ROM is lightning fast, and battery is a non-issue with this kernel. Only ever so slightly laggy when opening Handcent or galleries (when I add pics and albums have to rebuild the thumbnails), but what the hell, it's only running 499mHz! Even fired up Avatar from my SD to check for stuttering, clipping, or audio lag. There were none!

OH!!!
Almost forgot!
I stumbled across this "trick" a while ago. Not sure if it ACTUALLY works, but at least to me it does.
It's called "Super Charging" your battery.
Charge with phone on until green light signifying charging is complete comes on
Disconnect charger
Shut off phone
Reconnect charger
Amber charging light will come
When amber changes to green, disconnect charger
When Green shuts off, reconnect charger.
Repeat process
I was bored this weekend, and did it for 4 hours continuously. Yeah, that is truly bored!
I had charged it so much that upon disconnecting the charger, waiting for the green light to go off, then reconnecting the charger, there was NO amber light. Straight to green. Tried it a few more times, with the same result.
Did it actually "supercharge" the battery? Who knows?
Did it take 3 1/2 days of use to break the 25% remaining mark? Yes it did!
So if you are bored, I mean CRAZY bored, what the hell! Give it a shot...

Thanks, but not willing to step into the realm of SBC kernels. However, I will try to go through a few charging cycles to see if my current NA kernel just needs to get broken in. I've also tried the charging method you stated above and while I did get good results, I'm unsure as to whether or not this is overcharging the phone so I decided not to do it again.
Anyways, I wiped batt stats last night after getting the full charge, so still on the drain and need to recharge to 100%; will report back after I go through a few cycles of charging.

Why not an SBC?? Because it fully charges your battery closer to 100% than a non-SBC?/
And don't buy into the hype of exploding batteries. That was handful of cases, that a) were all reported in the earliest days of SBC development, none since and were never fully attributed to the SBC kernel.
Also, you people that say drain til it dies, you DO realize that HTC STRONGLY recommends NOT doing that. According to HTC, you shouldn't recharge until you get below 50%, and no, I'm not gonna go look for the links, use the search feature.
I have a good method in my signature. Give it a try.

Can't argue with a battery that stays at 100% for 3+ hours then slowly drains versus unplugging it at 100%, blinking twice, and seeing 90% remaining...

Well, I'm no developer but if Netarchy says to beware in his latest kernel thread, even if for liability reasons, then that's good enough for me to stick with non-SBC until an SBC kernel is proven to be 100% safe. I think that's a perfectly valid justification to not use SBC for now.
I keep forgetting that we're not supposed to completely drain the battery. I guess I'll recharge when I hit 5 or 10%.
I'll take a look at your thread when I get a chance.

All threads (for the most part) say that, even ROM threads about not being liable if anything happens to your phone. Not even flashing a ROM is 100% safe but you do it anyway.
I've been using SBC since it was being tested the first time and I've never had one issue. No batteries have exploded, no chargers bursting into flames, and no phones have self-destructed.
If you want really good battery life, good performance, and want to try something other than Sense, CM7 and MIUI are really good ROMs. I would recommend Tiamat kernel (use 3.3.8 for now, 4.0.0 has some issues) and make sure to wipe batt stats and do a battery calibration. For good measure, you can try my BSM mod in my sig for even better battery life.

Yes, all threads use the release of liability clause, but NA specifically states in his most recent thread that SBC could potentially cause problems.
Gosh, so much peer pressure! I'm not saying I won't ever go to SBC, just when I feel like it's a bit more stable and all the kinks are worked out. Kind of like you probably shouldn't buy the first model year of a car since the chances of running into glitches is much higher than if you waited a bit for the bumps to get smoothed out. If I'm being paranoid -- well, it's all in the interest of my $200+ phone. Regardless, I appreciate all the replies.
I've heard about MIUI here and there. I guess I've stuck with Sense since that's all I've ever known, but maybe I'll start branching out to AOSP and MIUI. Does CM7 have full functionality now on the EVO?
I'm on my first recharge since wiping stats and it's the fastest recharge I've ever seen. Maybe I do need to just break the kernel in?

Help with battery life

I rooted my incredible about 2 weeks ago, and after jumping around from rom to rom, but finally settled on cm7. 1rc1. At first battery life was great, I could finally get through a full day of normal use. I'm running the stock kernel, conservative governor, 998/245, and a screen off profile of 384/245, and also on the conservative governor. Then I read something about wiping battery stats yielding better battery life, and so I looked up exactly how to do it, and now my battery life went way down. Can't get close to getting a full days use out of it anymore.

How did you do it? Maybe you did it wrong. Also it DOES take a couple days for it to fully re-calibrate, so give it a few days too if you haven't.

I charged the battery fully with it powered on. Then turned the device off and plugged it back in and waited for the light to turn green again. Then I booted it into recovery, and clicked wipe battery stats, and re booted the phone. Once it booted up I unplugged it and used it normally all day until the battery died and the phone shut itself off. Once I did that I plugged it into the charger and let it fully charge.

Sounds like you did everything right. I say give it 3-5 days (I know a long wait) but usually that does fix a lot of calibration issues.
and there's a calibration app? craziness! I must see this..

If you are still having battery life issues, I suggest you install Chad's latest stable incredikernel (7/06/2011). I use it with CM7 and get very good battery life. You might also find juice defender helpful; set it to aggressive. Also you may want to manually adjust screen brightness settings.

Yep... There is a battery calibration app and it really does work. Wipes the stats for you and rewrites them. Just search the market for battery calibration. Should be right at the top.

The nice thing about the kernel is you can flash a mod onto it that will charge the battery FAST. (If battery life is gonna suck, at least gimme fast charging!) Not sure its on the thread. It is on his blog page at incredikernel.com.

Battery life is back to normal. Just for the heck of it I did a full wipe, and and re installed cm7. 1 in recovery instead of rom manager, used the calibration App, and went thru 2 charging cycles. Thanks everyone!

You have to try different ones as they are dependent on your location.

Awesome. I'm going to flash his latest kernel and try it out. I'm gonna have to look up how to adjust the voltages correctly for the best results
Sent from my ADR6300 using Tapatalk

There isn't really a "right" way to do it, per se. This is what I'd recommend: on the voltage control screen, there are buttons at the top to increase or decrease the maximum and minimum voltages (in increments of 25). The top buttons apply this change to all frequencies instead of having to adjust the voltage on each individual frequency. I'd try dropping all voltages (maximum and minimum) by 50, and see if your phone is stable that way. There are apps that you can use to do a CPU stress test (setCPU does this), so try that and see if you run into any reboots or anything. If not, keep dropping the voltages (I'd do this in increments of 25) until you run into instability. Use the lowest possible voltages you can with your phone remaining stable and you should notice some increased battery life.
Hope this helps.

There isn't really a "right" way to do it, per se. This is what I'd recommend: on the voltage control screen, there are buttons at the top to increase or decrease the maximum and minimum voltages (in increments of 25). The top buttons apply this change to all frequencies instead of having to adjust the voltage on each individual frequency. I'd try dropping all voltages (maximum and minimum) by 50, and see if your phone is stable that way. There are apps that you can use to do a CPU stress test (setCPU does this), so try that and see if you run into any reboots or anything. If not, keep dropping the voltages (I'd do this in increments of 25) until you run into instability. Use the lowest possible voltages you can with your phone remaining stable and you should notice some increased battery life.

OK, thanks. Does the stress test on setcpu stop after a certain length of time? If not how long should I let it run?

I let it run for a few minutes. Just press back once and it will say how many milliseconds it was running and if there were any errors.

Battery nosedive upon wake? CM7 SZen kernel.

Hi, I was wondering if it's typical for the Evo's battery to take a rather large dip upon unlocking it after not using it for awhile but keeping it on. Around 15% under within the few minutes that I used it after waking it up from maybe about 4 hours or so of not using it and just keeping it locked without any phone calls or other disruptions.
Why does it seem to want to ramp up something like crazy when turning the phone on after not using it for awhile? Or does it actually need to do that to function? Thinking about trying out the conservative governor and jacking up the minimum MHz so the performance isn't horrid.
Using CM7.0.3.1 with SZen, have tried the SZ, smartass, and InteractiveX (current) governors.
Radios and what not are all up to date.

Trying other governors doesn't seem to help this issue at all (if it is an issue).

tried a reflash? I think i had some battery issues the first time i installed CM7. I currently use SZ 2.1 i think with SBC and BFS. My governer profile is set on savagezen and I get pretty good battery life. My phone never has huge battery drops unless I'm using the ever living crap out of it.

Nah, I had a 100% clean flash two times over, I reflashed last time for a different problem which was fixed because i was messing around with settings, not from the system/kernel. I mean I could reflash it again but I've had tons of clean flashes and always have noticed the issue, now that mostly everything else is fixed for me I'm getting around to this issue to see if it even is one.

Same problem drops 5% with in 2 minutes, I've calibrated tried cm7, miui, and stock they all do it...even bought a new battery...

Mine doesn't necessarily drop a certain % in a certain way/timeframe, just a large dip after not using it for awhile. As if it's taking an enormous amount of resources to try and wake itself back up and stay awake after being asleep for so long.

I switched to a SBC kernel and fixed this issue. used to drop from 100 to roughly 85 % in as little as 10 min off the charger

did you re-calibrate you battery stats???

This is w an extended battery and an amount of usage today...its all about finding the right combo.

I reset battery stats every new kernel/ROM I change. Is it useful for any reason to reset after switching governors? I'm going to try Tiamat next probably.

I use SZ as well, doesn't help it.
Or rather, there's no immediate drop like i said for me. Just quickly depletes after a long wait.

What do you use out of curiosity? I'd love for mine to have a steady drop like that instead of a massive dip, 8hrs on a very decent amount of use too. Even with the extended battery that seems like so much. Unless the extended is literally double the life?
