I've tried every version...AC & USB, but more USB testing. So far each (as I recall) has given me some -mA's but did not notice quick drain with any of them...each holds mV's pretty steady in narrow range even with -mA's. Using Myn RLS4, HW0003. Overall for whatever reason the old V4 Net 4.2.2 has been the best for me. It seems to charge quickly with positive mA's after hitting 100% till it gets to 0mA, mV's hold in a pretty narrow range, and seems to "resist" the -mV's better. BTW OS Monitor shows enabled and no real drain.

You are probably going to drive yourself crazy trying to eliminate all -mA's Seems it's much like how different ROM/kernel/HW, etc. combo's give completely different results for folks. As long as folks don't get serious battery drain after it gets fully charged on AC/USB (especially overnight chargers) even with some -mA's and relatively stable mV's all should be good!! :D

Thanks again for all you're doing.

[EVO 4G Android Development] ms79723:
haha yeah I am driving myself a little crazy here >.< I'm tugging on my hair (im too much of a wimp to even joke about pulling it haha) and now my 'fro is all uneven. But thats why I asked if it messed with performance. I think that a big loss of -mA (in the 30+ range) was the killer. But since the charger is in fact always on, and I force it on when the first -mA shows up, I guess that the -2mA isnt a bad thing at all.
[EVO 4G Android Development] mdwoods:
I could not agree more, with the normal kernel i would drop 10% in the first hour. With this i lost 10% in like 2.5 hours. He just might be chasing ghosts with the few -mA's we are seeing.

[EVO 4G Android Development] adambomb6:
Got it! You probably want to put this in the front page, or people will keep saying they see negs in Battery monitor widget.

So, v7, I've been on the charger for hours, hit 100% about two hours ago, so it is trying to hold the top charge:

-I see batt_current=-4 and sometimes a -2

-I seeeval_current=0.....seems to be rock solid on 0 I see no other numbers showing

-batt-vol=4199...almost always, I see one 4200, and then one 4206, probably got that while screen was on, but it went right back to 4199

THIS LOOKS REALLY GOOD!:)

It seems that v7 is holding it at 4200mV steady!

If there is anything else I'll be glad to check it out. I also see charging source=2, charging enable=2, full bat = 1500000, and over_vch=0 always.

NICE WORK! I think the battery monitor widget is not as useful for the fine tuning once you have it trickle charging down to 0mA (about 1 hour after 100% for me).
[EVO 4G Android Development] ms79723:
That's what I'm thinking.

So I'm gonna keep up this v7 for today to see if more people download it and report back with good results. I'm gonna disregard the -mA's unless its something huge like -100 while on the charger
[EVO 4G Android Development] resonance77:
v7 test results so far

Flashed v7 at 10:30am

Plugged phone into AC charger at 10:35am, battery at 66%

Reached 100% battery at 11:28am

Reached 0mA at 1:35pm

Experienced first -2mA at 2:02pm

Experienced first -4mA at 2:20pm

Checked OSMonitor.

charging_enabled=1 (has not turned off at all)

batt_current= is fluctuating between 0 and -4.

For the life of me I cannot figure out why im awake all the time. Ever since I flagged the original sbc kernels, ive been awake ever since. I've wiped data, cache, and dalvik and even used caulkins wipes, format and temp, and reinstalled myn v4 and upon initial reboot, it is still fully awake 24/7. Anyone have any suggestions? Ive changed kernels, from nets, to ziggy, and all now keep me awake.

- from my battery sucking vampire Evo
[EVO 4G Android Development] ms79723:
tell me how your draining is from 100-90% when you get to that point

You probably just added an app that is keeping it awake or somethin
[EVO 4G Android Development] DrRyder:
Okay. I just added the new kernel to my rom, included SetCPU, did a complete wipe and flash. So, hopefully SetCPU won't FC on me. :\
[EVO 4G Android Development] xlGmanlx:
make sure you auto detect after you flash a new kernel
[EVO 4G Android Development] edgemaster191:
Im using cm6.1.1 nightly 203 with savage beta 2 sbc v5 and im on 6 hours and 45 minutes and still at 89% with light usage. :-)

[EVO 4G Android Development] xlGmanlx:
isn't SBC tha shiite? We will donate and like it
[EVO 4G Android Development] DrRyder:
Gonna have to. I wiped everything and flashed my updated rom. Fresh start. I do this often, lol. I pretty much flash my rom every update to make sure it works.

Edit: No dice. Everytime I change the frequencies, SetCPU FCs. This is a real bummer...Does anyone know why this is happening? I removed the kernel tweaks so this should be the only thing that can modify the scaling/frequencies.
[EVO 4G Android Development] slugbug2010:
Look at OS Monitor and see what is constantly using your CPU. Or better get Spare Parts and look under partial wake time. That will tell you what is keeping your phone awake. Both ar emust have apps IMHO.
[EVO 4G Android Development] xlGmanlx:
uninstall setcpu wipe caches x2 and flash again then install setcpu, see if that works
[EVO 4G Android Development] VisedMonk:
FWIW, I got some -mA's but not the drastic drop from 100% to 90%. I ran the battery down to about 80% and now I'm re-testing the v7 in connection with the OS monitor like you suggested. I'll update and post screenshots later.
[EVO 4G Android Development] DrRyder:
Figured it out...2.04 doesn't work too well. Probably because of the new support for Desire HD, Z, etc. I downgraded it to 2.03 and worked fine. :| Gotta update and flash my rom again.
[EVO 4G Android Development] Stroid01:
this is just about my exact situation using v3 of 4.2.2. i lose -mA but my overall stays around 4200mV I still get fantastic battery life after i unplug though.
[EVO 4G Android Development] Rene2.5RS:
I just wanted to say thank you for this.

I flashed SBC for Netarchy's 4.2.2 Non-Havs yesterday and today the results are amazing. I unplugged at 8:52am and it is now 2:53pm and I am still at 81%
[EVO 4G Android Development] CheesyNutz:
Is this while charging or unplugged?

from my phone duh
[EVO 4G Android Development] xlGmanlx:
i would assume during charging to see if you are getting -ma's, when unplugged you will always get -ma's due to battery discharging
[EVO 4G Android Development] ms79723:
For those wanting AOSP kernels..Zendroid just updated his with SBC. He has the v7 tweaks. There is Savage Kernel as well. Then I update BCnice's kernel for myself as well just to play around and test stuff(if anyone wants to try that one, feel free to pm. This one gets updated before the other two).
[EVO 4G Android Development] intheb0x:
I'm using the newest file, so I have no idea what you're talking about.

I had my phone on the charger for 10hours and woke up at 50percent.

Check out v7
[EVO 4G Android Development] ms79723:
For some reason, whenever i reboot out of recovery with the phone connected to USB, i see problems and charging_enabled = 0. But once I unplug my phone then plug it back in, its all good. I wonder why it does that...
[EVO 4G Android Development] slugbug2010:
I'm hoping the 110 degree temp doesn't fry my SD Card :eek:

I know the phone/battery has an auto-shut off if it gets too hot, but at what point does it mess up the SD Card? That tiny little thing is sitting right under my blazing hot battery right now.
[EVO 4G Android Development] bmark34:
I didn't add any apps, as I checked it right after the initial boot and it stayed awake with the screen off for about 2 hours until I loaded apps...ill keep messing around with it

MS, I sent ya a PM this morning... did you see it?
[EVO 4G Android Development] VisedMonk:
I tested the v7 kernel for you again, and as you'll see from the attached screenshots I got some -mA's but the battery voltage held steady for well over an hour after I hit 100%.

100% at 2:14 pm with 4209 mV's. By 2:16/17, I was at 100% but 4202 or 4203 mV's. When I took the phone off AC at 3:23 p.m., I was getting some -mA's but was steady at 4202 or 4203 mV's. No battery related messages from os monitor during this time.

I'll edit the post with battery life later, but I suspect it will only confirm my earlier test.

Calkulin's EViO 2 v1.7.1

SBC for Netarchy's 4.1.9.1 More Aggressive v1.7 build

**EDIT**

2 hours off the charger with heavy use and my battery has dropped from 100% to 81%

-several emails and texts

-about 10 mins of voice calls

-some web to keep up with this thread

-some market, a couple of new apps

-metamorph extraction and application

-titanium backup of my user apps

On stock kernel my battery would be below 70% with the above usage.

MS,

running v7, got my first bonnafide 0's for ma, so far so good, will let you know
[EVO 4G Android Development] slugbug2010:
Using v7.

It took a while to get there, but I'm now between 0/2 mAs. Looks like max is around 4213 or so, mostly 4200. No (-)s

AND I am streaming Pandora. I know, I know, we're suppose to do this at night, but I steam music all day so I HAVE to be plugged in or the battery WILL die. Streaming music doesn't use much, but enough to kill the battery in an 8 hour day, that is for sure.

I'm gonna try v1.7 since v1.4 had my phone last only 8 hours.
[EVO 4G Android Development] einsteins:
MS

I have this v7 running as I believe you wanted it to.

* Installed v7 and started charging at 10:43am 78%

* Hit 100% at 11:49am 50mA 4199mV

* hit 0mA at 12:40pm

* Stayed at 0mA for 3 cycles and then 2mA then 0mA for 3 cycles then 2mA all at rock solid 4198 mV

* 12:47 removed from charger started web surfing and texting continuously to test drain.

* Finally hit 90% at 1:21pm after continuous websurfing and texting with wifi on also.

* now at 2:48pm with continued use I am at 78%

I believe these are excellent results compared to previous battery drain rates that I was experiencing.

I never saw any -mA reading after an hour on charge at 100%

I hope this is helpful.....

Please let me know if I can provide any further information that can help you.

i jumped ship on Savage, trying out zendroid 1.01 BFS-AVS

speed is night and day faster, but i'm a little concerned about my battery. temp is stuck at 34c, according to system monitor everything is idle (no crazy cpu usage) also no wake lock keeping it awake.

what are you guys averaging for battery temp at idle? i'm using a seidio 3500mah

Edit: it seems to have calmed down a little, down to 29c. not to bad

What is the exact name and publisher of the app you took those screenshots from? I want to use it to monitor my charge progress now that I have flashed one of these bad boys and when I type in battery monitor on the market I get quite a few results. Thanks.
[EVO 4G Android Development] Mohawka:
Last nite I updated to 3.70 fresh rom and also updated to sbc 4.2.2 and this morning my phone was off and would not turn on so I grabbed my hero battery put it in my evo and good to go but I think there might b a bug or something in the kernel as I have been using kernel 131 for a week or so without issue the the first nite I use the sbc I get a broke battery but I really love the 131 version it has really improved my battery life

Edit. Upon further reading I found this is a known bug about the charger not charging and my battery was so dead it wouldn't take a charge. Now I got it charging and running my hero phone just fine so mayb ill try the 4.2.2 again

I just installed v7 on my phone. I hit 100% @ 1:33. Just checked the log after sending out some emails and txting and I'm at 98% @ 1:45. Pretty good for me. Usually when I take it off the charger once its full I usually drop 10% after 10 mins with the same amount of use. We'll see how it goes the rest of the day. I'm using Myn's ROM

I'm using the cm6 kernal and have to say this is the best battery life i have ever gotten with the evo. Thanks to the developers.

This Kerel addresses that exact situation of the battery dropping almost instantly when removed from the charger by using a trickle charge to fully charge the battery and control when the charger shuts off.

Had to test out sbc 4.2.2 more with my seidio 3500. Wasn't using it because my clips broke on my battery cover. Wow, surfed xda for 10 mins and my kid watched handy manny for 25 mins and then sent and received 10 texts then surfed for another 10. Went from 100 to 91.

unplugged at 3:50p cst.

from 3:50p-4:09p cst went to the store. sent a few txt's for ingredients needed. also checked facebook. all on 3g network. at 4:09p i dropped to 99% batt. also took 7 screenshots of things that are running and such for later use after testing.

testing this over the next 24hrs.

Update: 1hr off usb charge and only down 6%!
[EVO 4G Android Development] rushco:
The latest ones enabled USB trickle charging. I don't need that so I am staying on an older one that is working great for me. I suggest you don't change what is working unless you want USB trickle charging.

sbc 132 breaks support for camera with htc evo

hardware 0004

myn rls 4

What to do? It seems this has been reported, but am I stuck with stock kernel if I want to use camera?
[EVO 4G Android Development] DraeGZ:
Yeah I use my phone for USB Tethering also so guess I should flash it.

EDIT : I'm a " SENIOR " BABY :cool: .. Won't be like this when it refers to my age though :p
[EVO 4G Android Development] thenewguy821:
It wasn't the kernel that broke your camera.

The new hardware doesn't support any of the custom kernels, all will cause camera problems. Until the source is released for the stock kernels, 0004 phones will have to use stock kernels.
[EVO 4G Android Development] aph:
Yeah this is a good point, the first 2 posts look like they were written by a programmer (which they were) :p
[EVO 4G Android Development] roygbiver:
Yeah, that's what I've been reading:( So there's no way to get the charging/battery improvements if I want to still use my camera?
[EVO 4G Android Development] leenypost:
unfortunately not. for now at least. I hear kernal source should be released pretty soon though and then developers can make things just like this for you too.

For now I would stick with HTC #15... Best stock one IMHO.
[EVO 4G Android Development] adamantypants:
Well that's not true. I'm on the new hardware (0004, but didn't update and had old bootloader) and I've run no less than 5 different kernels trying to find one for me. I'm on Myn's ROM with RLS4 and have used my camera no problem; all the way up to 8mp. I can't say for sure that I've used the camera with every kernel but I don't recall having ever had issues with it.
[EVO 4G Android Development] roygbiver:
Thanks, do you know where I can get the zip for that? And there's no non-kernel way to fix the battery charging issue?
[EVO 4G Android Development] leenypost:
There are many programs that some folks think help, others think they don't. I would try HTC #15 by itself for about a week and see how you like it. It has pretty good battery life for a stock Kernal.

As for finding it, if you find the thread by RicSim78 called [ROM] Azrael V3.0 and you click on the paperclip next to that thread it will be in there 4 or 5 times. Just click any of those links and it will download to the computer automatically.

Unless HTC messed up and sent out a shipment marked 004 that was really 003???

I am wanting to try a new kernal and am having a tough time interpreting all this info. I think this one might be best for me, but I am lost.

Thanks for all your hard work!
[EVO 4G Android Development] elefntkpr:
I've just been accepting this but now I'm curious. I've flashed the custom net kernals and variations several times and it still black screens my camera. The phone "claims" to be HW0003. Am I missing something or could it be they started using the new camera chip before they changed the HW version number? I really dig the new kernals and this one I'm very interested in but I use my camera at work all the time.
[EVO 4G Android Development] leenypost:
They did change the new camera chips before switching HW #'s so there are some 003's out there that should be treated as 004's...

And I suppose there are also 2 004's out there that can be treated as 003's
[EVO 4G Android Development] roygbiver:
I'm being told I should use #17 because I have an evo and 004 hardware???
[EVO 4G Android Development] leenypost:
17 works as well.. But 15 is actually the newest one that works with the new camera chip. 17 and 15 are the only 2 that work.

I have used both... with old hardware... But out of the 2, 15 was better for me... that's why I suggest it.
