The kernel doesn't control the charge when the phone is off, so it doesn't charge as completely. It basically uses the oem bump charge method.
[EVO 4G Android Development] mikeDCMDVA:
Is it best to flash this after I have charged my phone to 100%?
[EVO 4G Android Development] rushco:
Check the battery monitor log for any negative ma. Tough to say what happened unless we see the log.
[EVO 4G Android Development] Hisma:
my battery has drained 10% in about 30 minutes, from a full charge.
[EVO 4G Android Development] mrwicked:
Are all the kernel's the same way on here?
[EVO 4G Android Development] dahauss:
are you sure it was FULL? just letting it charge until the green light comes on isnt enough.. if using TRICKLE, you need to charge until 0MA. if using BUNP I dont know what it needs to charge to but 30 minutes or more past the green light is good...
[EVO 4G Android Development] dahauss:
YES.. the KERNEL is SOFTWARE and if the phone is off, it cant work...
[EVO 4G Android Development] dahauss:
SO Im still testing BUMP charge. I dont know if its a good a trickle BUT it might be safer.. anyway, 8am OFF, now 10:35 and with ONLY one call for 10 minutes I am at 99%.
[EVO 4G Android Development] dahauss:
DO any of the V7 trickle charges have any issues with using the phone while it is on the charger? on 131 I had an issue where using it while in the car with GOOGLE GPS made the phone 110 degrees... I still need to try this on the V8 I am running now...
[EVO 4G Android Development] mikeDCMDVA:
How do you bump charge the Evo?
[EVO 4G Android Development] dahauss:
it is the V8 kernel in the second post that says BUMP. its works for any room (including sense which I am running)

so far so good. I like the fact that it doesnt keep a constant charge on the phone BUT I dont know at what MA drop is starts charging again. it works different then the standard BUMP charger which waits till 90%
[EVO 4G Android Development] thenewguy821:
I'm starting to wonder why ms hasn't shed any light on this yet. He popped in for a couple posts and still left the one question that has been asked repeatedly unanswered.
[EVO 4G Android Development] dahauss:
would love to know as well!
[EVO 4G Android Development] mikeDCMDVA:
Thanks for the info! I just loaded up the v8 kernel as well, now I am turning off my phone to bump charge it.

azrael 3.0 002

both times i only peak at 4190 and then off charger i drop to only 4150 if im lucky - possibly a battery hoggin app???
[EVO 4G Android Development] NewZJ:
don't turn the phone off
[EVO 4G Android Development] dahauss:
TURN OFF PHONE? you cant TURN it off or it doesnt work.. NONE of the KERNELS work if the PHONE IS OFF because the KERNEL is SOFTWARE that NEEDS TO BE RUNNING.. I am running V8 with SET CPU. BUT I Never turn phone off... JUST screen off (not talking about SETCPU but actually SCREEN OFF .. LOL). If you turn phone off, you will get some other sort of charging... whatever the phone does on its own with no software running and it wont take advantage of the new kernel.
[EVO 4G Android Development] squigglyrulez:
misread post..
[EVO 4G Android Development] mikeDCMDVA:
Wow, thanks guys. I turned the phone back on and kept it charging.
[EVO 4G Android Development] dahauss:
If the PHONE is OFF, its not using the KERNEL. LISTEN, EVERYONE NEEDS TO UNDERSTAND.. IF YOU ARE USING A CUSTOM KERNEL, the phone NEEDS TO BE ON so the KERNEL SOFTWARE CAN RUN. without the phone on, you are only getting whatever charge the phone does on its own when it is powered off...
[EVO 4G Android Development] EndlessDissent:
The post he linked to had nothing to do with the phone being off. It's about updating the radios.
[EVO 4G Android Development] SilverZero:
I used v7 for a couple of days, and my battery life was worse than with regular netarchy 4.1.9.1 (same types). So I went back, and I'm getting my great battery life again. Maybe I'll consider the bump charging version, but I really have no problems as-is so I guess I don't need to fix what's not broken. :)
[EVO 4G Android Development] CaptainMorgan:
Trickle charging is great but I have had a burning (pun intended) question:

I live in Phoenix, and while it has been freezing cold this winter, I know that the hell we call summer here is only 5 months away, how dangerous would charging like this be in a car that is sure to get up to 160F inside before the A/C cools it down? Last thing I want is my phone to blow up. And, does bump charging keep it at a cooler temp consistently? I really don't worry about battery degradation anyways since I replace my batteries every 6 months (damn you Apple!) I'm just concerned about heat.
[EVO 4G Android Development] SilverZero:
He was quoting a post that was quoting another post, which did deal with the phone being off. In context, his rant is spot-on. He just didn't proofread his work. :)

You shouldn't have your phone in that kind of heat EVER, regardless of the kernel you're using.
[EVO 4G Android Development] NewZJ:
your battery can only withstand 140°f you need to keep it cool
[EVO 4G Android Development] rushco:
Charging is charging till it gets to 100%. Then the kernel does its thing. So plugging it in at 40% with stock kernel or this one will not make it explode or cause damage. Now charging it after 100% my phone never gets hot so I really don't see a problem.
[EVO 4G Android Development] flipper12:
I had the same experience. Although it took a LONG time for it to leave 100%, once it did, my battery depleted faster.

I read on Net's post about it possibly having to do with the kernel not matching well with the 1.90 PRI version. That's what I have on my phone so I'm wondering if anyone else has this issue.
[EVO 4G Android Development] mikeDCMDVA:
I am getting a mix of + and - mA's. Is this normal and alright?
[EVO 4G Android Development] EndlessDissent:
Were you using the phone after it reached 100%? If so, you have to stop using the phone when it reaches 100% or the charger will turn itself off, which would explain the high negative values.
[EVO 4G Android Development] mikeDCMDVA:
Ah, I did use it for a text message or two, then to take this screenshot. Its sitting there on 100% still not being used since then.
[EVO 4G Android Development] dahauss:
I think v7 f& V8 Trickle fixes the issue with using the phone while plugged in. I need to be able to use my phone when it is plugged in .. especially in the car with GOOGLE NAVIGATION and STREAMING MUSIC...
[EVO 4G Android Development] ms79723:
savage aosp kernel uses v7 so its the same thing. but if you're talking about bc's v7 or savage's v7l...which is better...I would go with savagekernel.

Well my bump charging happens automatically in v8. So no need to turn the phone off or any of that nonsense. Once the phone reaches 100% it would turn off the charger, then turn itself back on...basically acting as if you were plugging/unplugging.
[EVO 4G Android Development] thenewguy821:
Ok, So it doesn't turn off and drop to a set percentage or voltage, it just cycles the Charge on/Charge off, each time turning off at 100% then turning right back on? If so, that is very similar to one of the "Battery life tricks" that was floating around before. (Plug in phone till 100%, Power off and unplug, plug in till light turns green, unplug, plug in till light turns green again, repeat x number of times) This just does it on its own, without the need to power down the phone?

Is there any chance of this method being added to any of the other kernels? I know Ziggy's comment has raised some concerns about volatility with the trickle charge. ( I know you covered this already, not trying to bring it back up). Some people have went to the v8 kernel since it works on both AOSP and Sense Roms, but in Sense Roms, it seems there are issues with Bluetooth.

I am currently using the 4.3 version with your tweak installed, and have great battery life and the phone always stays cool on the charger, so I am not too concerned.
[EVO 4G Android Development] mikeDCMDVA:
Ouch...using MikFroyo 3.25 with v8....battery went from 100 to 83 in one hour...I kept 4G on the whole time, sent two or three text messages, used Facebook a few times and checked into a location using Foursquare. Just basic use of the phone was dropping that battery like crazy.
[EVO 4G Android Development] xlGmanlx:
4G will do that for you, and v8 is just BS kernel patched with SBC

[EVO 4G Android Development] mikeDCMDVA:
My co worker has an Evo, using the newer MikFroyo build...turned on 4G same time as me, and my battery dropped much faster than his. He did not flash a different kernel either. Mine was already at 92% while his was at 98%. Strange...

its your 4g dude... thats whats killing you... turn it off untill you need it...

ran tests on this... 4g was the killer

yea but did you both do the exact same thing on the phones (ie. FB - 4SQUARE- ECT. )

No kidding - I work all day in a building with wifi available to me and when I go home I have no service in my house. In essence, I'm not even using 4G and I couldn't if I wanted to when I need it.
[EVO 4G Android Development] xlGmanlx:
meh....its nice the times when your out of office or your home base and you want to check something fast or if you want to setup a wireless tether, but for the most part my 4G doesn't get used all that much because i have wifi at home and no signal at work
[EVO 4G Android Development] :
i read around since i wasnt getting my battery to hit atleast 4199 off the charger (thinking something was using a constant drain that it couldnt stabilize the trickle charge)- and found a possible reason to the pri 1.90 so i downgraded my 002 evo to 1.77 - we shall see if my batt improves
[EVO 4G Android Development] dahauss:
but at what voltage does it come back on and charge once it turns off the charger?? Is BUMP safer then TRICKLE? does BUMP give you as good a battery charge as trickle??

We really know nothing about the V8 kernel BUMP other then what I get from running it...
[EVO 4G Android Development] mikeDCMDVA:
sand man, my pri is 1.34_003...should I change mine?
[EVO 4G Android Development] dahauss:
I dont think it does it that fast.. I think it charges t0 100% then bumps then waits for a voltgage drop then bumps back up.. I say this because I leave the phone on the charger overnight and when I wake up and look at the battery graph you can see where it lost voltage. You can also see in the battery widget that it IS discharging for a short period of time..

OH and BTW - I am using V8 with NO BLUETOOTH ISSUES on a SENSE ROM.. NON.. I just use my bluetooth car spekerphone about 5 minutes ago and over the weekend use my bluetooth headphones to listen to streaming radio..

what bluetooth errors are happening on V8?

EDIT: I searched the thread and saw the bluetooth error some people were having. Im on SPRINT LOVERS ROM SENSE no issue on V8.

no - if you are charging the phone there should be all plus' but if your using the phone while on charge then this will happen and also the battery will get warmer. all from the trickle charge kernels.

bump charge you may see negatives. but they shouldnt be large negatives

[EVO 4G Android Development] dcharleyultra:
Ummm, you will see positive values up until just over 4200mV. Then you see positive and negative values so that your charge status stays at 100% and the mV around 4200.

I think that the #2 is the Dev's revision, not the HTC Kernel version. And speaking of which, has anyone been able to build a decent comparison between the SBC HTC #15 and like the SBC TM 4.2.2 kernels with regards to battery life?

Question

Hey just wondering if anyone has tried to flash a different kernel after this one? I tried to flash a different kernel after this one and phone would not pass htc white screen. Only way to change kernel was to flash a different rom.

This may not be from the kernel so I am going to flash a new recovery today.

Just looking for help....
[EVO 4G Android Development] originalmachine:
Couldn't find the answer, just the developer saying he should port it over. Is there a version of this kernel for the HTC Incredible yet? Thanks.
[EVO 4G Android Development] xlGmanlx:
his github is up to date so your favorite kernel dev could grab those commits and port them to any kernel. Does the incredible have the same charging issues as the evo?

What kernal are you using
[EVO 4G Android Development] dahauss:
Everyone is posting the SAME THING.. Look.. there is the charging the way the phone was designed.. then there is TRICKLE CHARGE KERNELS and then a BUMP CHARGE KERNEL. No one knows is ANYTHING is going to happen to our phones battery. We dont know if BUMP is better then trickle for safety or both are the same in terms of safety. We dont know anything.. We DO know that both BUMP and TRICKLE give us terrific battery life DEPENDING on what is running on your phone, usage pattern, etc.
[EVO 4G Android Development] okaytran:
so the theory is that this kernel won't overcharge because the phone is running and taking up energy at the same time? what if we charge our phones while they are off?
[EVO 4G Android Development] rushco:
Then the kernel mod can't do its thing. You see the charging is the same till it reaches 100% and then it trickle charges till the battery is really charged and keeps it there. People say because it keeps charging it is slowly killing the inside of the battery. It could be years before the thing dies or months. No one really knows yet.

The end.
[EVO 4G Android Development] mikeDCMDVA:
Took the phone off the charger 5 1/2 hours ago.

I have texted, surfed the web, made a phone call or two. Facebooked, Foursquared, played Gun Brothers Beta (massive game), went through my picture gallery, had my phone inside barely having any signal while on WiFi. Probably some more, but currently the phone is at 72%. I would say not bad!

I'll be honest, for about 30 minutes of that 5 1/2 hours, my cell was on car charger. Then put back on for another 20 minutes or so after taking it off for an hour (was at the mall).

Still good IMO.

Hope thats a good feedback for you guys!

Running:

MikFroyo 3.25

PRI version 1.77_003

v8 Kernel
[EVO 4G Android Development] dahauss:
Does that mean you will stay with v8? I honestly like v8 especially if you leave it on the charger and use it like I do and for the fact that it doesn't leave constant power to the battery.
[EVO 4G Android Development] dahauss:
That's why I'm testing bump charge. It doesn't constant power to the battery.
[EVO 4G Android Development] boriqua2000:
with which roms will this work on? :confused:
[EVO 4G Android Development] dahauss:
HMMMM

Still using V8 BUT this morning at 7am, I took the phone off the charger (it had been on since 10PM last night). The battery level said 95% .. Put it back on the charger till 7:50AM. Took it off and it way now at 100%. Went in the car to go to work for 10 minutes and put it on the car charger.. Got to work and its back at 95% 4175MV. When I got to work it said it was charging again with 11MA, then got to 0MA and now shows -10MA then 0MA then -28MA and -6MA while on the charger. As I am writing this, I took it off the charger and it shows 100% and 4208. I'll keep testing but does anyone know why this might have happened??

Edit: I also notice this morning that there is a LAG on startup that there wasnt before. I do have a Screen OFF SETCPU profile 245/245 power save but there has never been a lag when I unlock the phone with v8. I even notice I can unlock the phone, move to the page with the setcpu widget and see 245/245 and then see it change... Hmmm.. any ideas??
[EVO 4G Android Development] BuddaBelly:
V8 is a bump charge so based on what you wrote it's doing exactly what its supposed to do. Thats exactly what the HTC charging profile does just not as often. Im not sure if the v8 version starts charging on a percentage or on actual voltage.
[EVO 4G Android Development] dahauss:
what I dont know is does the new AUTO-BUMP charge pick a different MV or % before it starts charging again (different then stock charging)? because in the few days I was running this, I never took the phone off the charger at less then 100%. If I stand a chance of the battery being at less then 100% with V8, then there is no point to using it as it sounds like it is no better then stock.

Also one question, do any of the V7 or 131 kernels FIX THE ISSUE with using the phone while on the charger and it getting HOT and the charger shutting off so you dont need to plug and re-plug to get to to start charging again? AND, when the trickle charge kernels say 0MA, does that mean NO current is being applied to the battery?

Thanks...
[EVO 4G Android Development] mikeDCMDVA:
Phone now at 47% with no charge since 6pm est yesterday..browsing away right now...not sure if keeping but I don't think this is too bad..not even using setcpu yet
[EVO 4G Android Development] dahauss:
Well I woke up this morning using V8 with battery at 95% ON CHARGER so it BUMPED and then discharged.. I wish we knew if it was % or MA that it bumped at and what it was. I dont like that I work up with 95%... I would like to go back to V7 or 131 IF I knew trickle was SAFE and if I knew that I could use the phone wile plugged in and it wouldnt get 110 degrees hot and it wouldnt shut off the charger needing a re-plug to get it to start again. I use the phone in the car with google navigation and streaming audio (and calls)

you know what I noticed yesterday...I would glance at my phone...one minute it would be fully charged at 95% then the next few minutes later would go to 100%....and somehow back to 95% a few minutes after that...so you're not alone

how does trickle work? i've heard bad things about trickle....like melting the battery....i don't know the engineering of it though and how the logic of it is
[EVO 4G Android Development] theboundless:
Hi, I've tried a few of your sbc kernels as well as net's, but every time I hook up the phone to charge it, it shuts off the usb connection and the charging light goes off in a second. As well as not charging, I seem to have no connection ability with the computer too. Any ideas why? I would love to take advantage of the trickle charging. I'm running fresh 3.4.0.1
[EVO 4G Android Development] dahauss:
For anyone who is using V8 BUMP, and you leave you phone on the charger over night, I would like to know if you ever wake up with your battery less then 100%? As I mentioned in another message, mine was 95%. Not good if I am trying to get better battery life. This was the first time this happened with the V8 over the 2-3 days I was using it. it always was at 100% or more. I am also trying to find some REAL evidence that trickle charging are batteries is BAD. I did notice on trickle when using my phone it was at 110 degrees with 30 minutes of screen on in the car....

I wish MS would chime in and let us know how the V8 kernel works for auto-bump.. if it is a % or MA that it starts recharging at.. being at 95% on waking up with the phone on charger all night isnt much better then stock kernel...
[EVO 4G Android Development] dahauss:
I just notice that as well.. Pulled charger out.. it said 95% then jumped to 100% in less then 1 second... I wish MS would explain..

Also, I think I asked before, does either 131 or V7 fix the issue with using the phone wile on the charger? the issue was that when using the phone on the charger you would get the MA to high and it shuts off the charger so that you need to re-plug to get the charging going again.. I dont want that.. also my phone was 110 degrees when using trickle and keeping the phone in the cradle ON for 30+ minutes
[EVO 4G Android Development] SIGARM:
I installed HTC KERNEL #15 v7 on my Evo 4G a few days ago and am experiencing the same battery life as before the kernel update. The only difference is that the battery meter displays 100% for about an hour and then quickly drains to < 10% capacity before I turn in for the evening; whereas before the update the battery immediately drained 15-20% within the first hour after a recharge. I am not overclocked and haven't noticed any overheating issues. I'm considering reflashing the kernel back and revisiting when the next final version is released.
