....I guess I am another v8 bump user. Did you use a screen off profile? I have noticed yesterday that my battery got pretty hot (or maybe just the kick stand portion). Well another day on v8. Will try to get pictures of my usage today.
[EVO 4G Android Development] thenewguy821:
Yeah, every time I would look for info on the "Bump Charge", I came across MANY posts from you asking for the details, with nobody giving any insight. I am trying out the v8 also, and it seems to be running VERY nicely in my phone. (Myn's Rls5beta, Koni's Aloysius theme, 003 Hardware...) I saw the post from Ziggy as well, and it doesn't surprise me. I have run RC Cars for a few years now, and in the past few years, LiPo batteries have been the big thing. Because of the high cost of "Quality" batteries, a lot of people would buy the cheaper batteries, and not charge them right. It's an odd sight, to see a 40-50 Mph Remote control car start smoking, then burst into flames... Although the majority of times Problems would happen with the batteries, it was during discharge (People running High draw motors in batteries not designed to push that high current, causing the battery to be unstable), I have seen batteries burst while on charge. Again, this is mostly due to charging at too high of an amperage. Taking what I have seen with those batteries, and applying that knowledge to our phones, as long as the amperage isn't increased past the charging threshold, the batteries SHOULD be fine with the trickle charge.

Im using th 1800MAH Battery (from ebay). I did notice it get HOT while I was using GOOGLE NAVIGATION in the car connected to the car dock and car charger.. BUT that was with 131 kernel which keeps constant voltage. I havent tried THAT with the BUMP V8. I have a few profiles set.. my main profile is 128/998 SMARTASS and my screen off is 245/245 power save. I also have a CHARGING/FULL PROFILE 245/998 ON DEMAND so I get better usage of the phone while its plugged in...
[EVO 4G Android Development] dahauss:
if that is true, then is there any advantage of bump over trickle? I think there might BE for people like me who use the phone while on the charger or in the car with the car dock and car charger.

with trickle and CONSTANT POWER being given to the battery WHILE it is running something like GOOGLE NAVIGATION, the battery will really heat up.. when I had 131 installed, and I use GOOGLE NAV, my phone was at 110 degrees .... I need to try this on v8 when I get a chance but overall, the phone doesnt seem as hot with V8 since you dont have constant voltage applied.
[EVO 4G Android Development] dthomas03:
Wow a 110 degrees ...pretty hot! I guess for us v8 users have a lot of testing to do today.
[EVO 4G Android Development] cheebahawk:
Slight confusion due to the way the OP has the kernels organized on the first page:

Is the Version 8 BUMP method compatible with both Sense and ASOP ROMS? It comes right after Version 7 for ASOP Roms and no indication of whether it is for both or just for ASOP.

Also for V8 users, have you noticed any difference in terms of battery performance from V7? I assume the BUMP method is that once the battery hits 100% it stops trickle charging and will let it fall to 90% and then recharge overnight and this cycle continues?

Whereas the V7 trickle it will just keep charging at 100% and not let it fall below 100%?

Also another question I have is after reading Ziggy's post, why would trickle charging lead to degradation of battery or "danger of exploding battery"? It is my general noob knowledge that most phones do in fact trickle charge, Treos, iPhones, Motorola phones, etc. Is this incorrect? I would also assume that bump charging would be worse for the battery since your constantly (overnight) charging and recharging your phone automatically over time since it goes from 100-90 and then 100 again constantly?
[EVO 4G Android Development] thenewguy821:
v8 is listed as an AOSP kernel, but there have been many people who have tested it to be working with Sense as well. I switched to it yesterday, out of curiosity, and have had no problems running it with a Sense ROM (Myn's Warm 2.2 Rls5beta).

As for battery performance, I have only had it on one day, and so far it seems to be really good. I haven't had any lagging, phone seems just as responsive as with v7 (netarchy 4.2.1 CFS More aggressive and netarchy 4.3 CFS More aggressive), and battery life seems quite good. I was setting the Netarchy versions to conservative governor, through OS Monitor, but no other changes/profiles. In the v8, conservative is not an option for the governor, so I am using interactive with good results.

As for HOW the bump charging is achieved, we don't know yet. The stock HTC kernels would charge to 100% and turn off till the phone dropped to 90% then turn back on. That IS a bump charge. There have been numerous posts trying to get some more information on the Bump charging that MS has applied to v8, so far with no reply. We don't know if it charges by actual Mv, or if it goes by the phones estimate of percentage. We don't know how long it stays off when the high threshold is reached (Drop to 90%, 95%, 4100Mv???) These are still unanswered.

EDIT: After re-reading my post, I felt the need to add this... This is/was in NO WAY intended as an attack on MS. I know he is probably very busy and hasn't had time to check in/post. He has always been quick to try to resolve any questions/comments in the early stages of this kernel development, and I am sure he hasn't just given up. I was not trying to imply that he is just leaving us "high and dry" without an explanation, I was only pointing out the fact that currently, we still do not have answers on some of the questions the poster asked.
[EVO 4G Android Development] cheebahawk:
Hmm if that is the case, then it would seem that the V8 is probably similar or better than the HTC method of charging, which in my opinion sucks ass (the HTC version).

I hope MS has the time to let us normal folk know what the difference is between V8 method and the HTC method of bump charging...

Also not an attack on Ziggy, but his site/post on the 'dangers of trickle charging' wasnt that informative.

I was getting fantastic results with the v7 4.1.9.1 More and decided to try out the 131 More that is listed since everyone seems to be raving about it. Will also try out the 4.2.2. or whatever the latest version is and will report back in a day or two.

But I really hope this mystery with V8 is solved soon tho...
[EVO 4G Android Development] dirkyd3rk:
this kernel seems like its all about battery life, which is cool cause who doenst like awesome battery life. But im looking more for speed over trickle charge etc on fresh rom which i installed for the first time yesterday. Is this a kernel i should use for speed?, if so which one will you recommend theres like 20 of them in the op.
[EVO 4G Android Development] dahauss:
I get pretty good speed on my EVO with the V8 Kernel.. I dont overclock but SETCPU shows you can.
[EVO 4G Android Development] fixxxer2008:
getting decent battery life but not as good as before. i still say launcher pro is the culprit.
[EVO 4G Android Development] dirkyd3rk:
I just flashed the 4.2.2 cfs non havs and my camera broke i guess ill nandroid. It did let me overclock the heck out of this sucker though too bad.
[EVO 4G Android Development] stricklerjosh:
What hardware version are you? Probably have the new camera that works with new drivers only.

mikfroyo evo!
[EVO 4G Android Development] dirkyd3rk:
Yes I have the 0004 hardware I just checked, I'm just looking to overclock fresh Rom can you recommend a kernel or am I screwed since I have the new camera?
[EVO 4G Android Development] 94tbird:
screwed due to the new camera, the code for the newer kernels hasnt been released which is why there are no custom kernels for them
[EVO 4G Android Development] dirkyd3rk:
Lol ok makes sense thanks dudes. I guess ill rock 998mhz until I can push it further I appreciate the speedy responses.
[EVO 4G Android Development] dthomas03:
Dum question. But whats the easiest way to figure out which hardware you have
[EVO 4G Android Development] dirkyd3rk:
if youre in a sense rom just go to settings, then hardware information and it says it there.
[EVO 4G Android Development] thenewguy821:
Not true... The source for HTC kernel was released last week, and Netarchy has already built off it. If you go to netarchy's thread, he has the new kernel (net 4.3 w/camera support for 0004 hardware) listed. He has the regular version as well as the one with the SBC trickle charge mod.

Here's the link to net's thread: Netarchy's kernel thread

In all there are 16 versions of the 4.3 kernel. With or without SBC (Trickle charge) CFS, BFS, with or without HAVS
[EVO 4G Android Development] dirkyd3rk:
Ohh ok sweet dude thanks alot I'm headed there now.
[EVO 4G Android Development] thenewguy821:
No problem...
[EVO 4G Android Development] dahauss:
So is there no kernel for the 004 hardware and new camera that is for SENSE?

I thought the HTC stock one would work...
[EVO 4G Android Development] thenewguy821:
3 posts up from yours, I posted a link to netarchy's thread which has the new kernel (netarchy's 4.3) for sense and new hardware.

With and without charging mod
[EVO 4G Android Development] dirkyd3rk:
There IS a kernel that works check the link that the guy above me posted to netarchy/toast thread with kernels that support the 0004 hardware. I just flashed one and it works.
[EVO 4G Android Development] Brian Rubin:
Ah, fair enough, but yeah, not inclined to try it again. :)
[EVO 4G Android Development] dahauss:
didnt see that.. I assume it is TRICKLE CHARGE? what about BUMP?
[EVO 4G Android Development] dirkyd3rk:
There's about 15 diff kernels I'm using the no havs no trickle no undervolt lol just wanted to overclock. You should go check it out dude
[EVO 4G Android Development] dahauss:
Well Im using it for the battery life and to underclock when screen off...

v8 and Bluetooth Failure

Just flashed this last night and everything seemed to be working great until this morning when i tried to turn on Bluetooth for my drive to the office. Bluetooth icon would change from dim to normal but then it would go back to dim and the notification icon never came on. Checked the logs and found this:

E/bluedroid( 156): bt_enable: Timeout waiting for HCI device to come up

Any ideas?

[EVO 4G Android Development] LuvThyMetal:
So far I'm getting the best results with SBC for Netarchy's 4.2.2 Less Aggressive CFS kernel on my phone. I just checked battery life and its at 100% with 5 hours 11 minutes of the charger and light use! Not bad if you ask me.
[EVO 4G Android Development] dahauss:
How is that possible? What is running on the phone and what did you do with the phone
[EVO 4G Android Development] stargaterules:
So what is the real story on trickle charging then? Ziggy said it can cause your battery to become unstable or even explode. Is that where the general consensus is? Why is nobody discussing these concerns considering there are so many kernels out there using trickle charging?
[EVO 4G Android Development] NewZJ:
yes, it can cause your battery to die faster

I dont care, batterys are cheap and sbc isn't killing it fast
[EVO 4G Android Development] stargaterules:
I don't believe that BS. My phone can be idle 40+ hours but with constant usage can only last max 17. Where are your screenshots with activity to prove this?
[EVO 4G Android Development] 08tundra:
ok ill let u know
[EVO 4G Android Development] NewZJ:
Woot! finally hit 99%. had to turn off wifi, turn up brightness and start using google nav
[EVO 4G Android Development] lil-dice:
so....can someone give a recap of wtf is going on in this thread?
[EVO 4G Android Development] ceg1792:
That's what I suggested.

I also think he should download cat log, shows all processes, delvik should always run, but that is it. Delvik is what launches the apk for apps.

[EVO 4G Android Development] 08tundra:
i texted u and downloaded cat log im going to install a new kernel now ill let u know
[EVO 4G Android Development] soto24:
Thanks bro I will try to root this thing hope I don't ruin it but o well what widgets do I need
[EVO 4G Android Development] xlGmanlx:
So should we wait for the battery to be fully charged before we flash your newest?
[EVO 4G Android Development] ceg1792:
MS, my phone runs great when on usb charge. No excessive heat or anything like when I was on AC outlet.

Sent from an unknown rom.
[EVO 4G Android Development] ms79723:
if you want to witness the great charging, then just charge while the phone is off, then turn it on with it plugged in and watch it continue to charge on 100% :)

I tried this on USB and I got drainage once hitting 100%, so I assme this only works with AC at the moment. I gotta add in USB support later on tonight or maybe tomorrow.

After build

129 it will not sleep tried 131 still not sleeping
[EVO 4G Android Development] tonwarr.the.incredible:
1 hour and 10 minutes later after pretty heavy use I'm finally down to 90%!
[EVO 4G Android Development] 08tundra:
got the same problem we are working on the issue
[EVO 4G Android Development] za.sidd:
So is this a good solution to solve the EVO battery trickle issue if you're mainly charging using the AC and want to leave it plugged in overnight? Or is it still in beta builds?
[EVO 4G Android Development] ms79723:
thank ya thank ya :)

Well idk..the difference between 129 and 130 is the voltage regulation. The difference between 129 and 131 is how it sleeps in which I had it set so that the apps would sleep in idle time and i took away the option to sleep in 129 but somehow that allowed the best sleeping i've ever seen...I gotta play with it.

If your charging voltage doesnt exceed 4.2V then just use 129 and you'll get the same effect. If your charging voltage does go over 4.2V and you still cant sleep, then gimme a bit and I'll put something up.
[EVO 4G Android Development] 08tundra:
this is what i got on the battery monitor widget
[EVO 4G Android Development] ms79723:
This works great on AC and on the builds 129,130 and 131, I have yet to see any draining from charging past 100%. So its good to go. Now some users are having some sleeping issues and im just confused as to why, but we'll get that ironed out soon.
[EVO 4G Android Development] ms79723:
hell yeah! :D I had to work heavy to get mine to 95%. Im amazed by how much more time we're getting with this.

Ok you're over 4200 so your phone is gonna be a little sensitive. If you use your phone a lot while its charging, its gonna spike over 4211 and thats gonna shut the charger off. for best results, your phone has to be completely idle.

I should probably post that on the main page...
[EVO 4G Android Development] rushco:
People are talking about it but not in this thread. People in this thread don't care or else why would they be here talking and trying to get the best kernel for their phones. Look in the Q & A part or general part for people complaining about this mod. We are the risk takers.
[EVO 4G Android Development] LuvThyMetal:
How is it possible? No idea! But it sure is working for me. I been on this kernel for a couple days and it seems it gets better each day. I'm a noob with this stuff, i don't do anything to my phone just installed Myns Rom and tried a few kernels, nothing else.

Quick dumb question, I wiped the cache and dalvik, flash the less havs .zip and it showed lines across my screen, then it went back to normal. is this what it normally does?
[EVO 4G Android Development] kgbaseball:
Like many other EVO users, I had grown tired of the first 10% of my battery draining within the first few minutes of being unplugged from a charger.

I decided to root my phone a couple days ago to try and take advantage of the various ROMs, programs, and kernels available to try and increase battery life. I use my phone constantly during the day and really wanted to see if I could squeeze some extra juice out of it.

And boy have I. I discovered this kernel a couple days ago and have been thoroughly impressed thus far. The biggest thing that caught my eye about this kernel was the type of charging it does. I must say it works just as advertised. I lasted 64 MINUTES on 100% this morning before it moved to 99%. 64! And now, after being unplugged for well over 12 hours (and a regular day of pretty heavy use) I'm still at 62%.

I am thrilled with the results from using this kernel so far and would like to give a big thank you to the developers!

Jut in case anybody was wondering, I'm using the stock EVO 2.2 with root, along with Juice Defender Ultimate and setCPU to get these results.
[EVO 4G Android Development] stargaterules:
See, I could have been at 100% forever if I didn't touch the phone. This is after 15 texts and 2 phone calls- 10 min total.
[EVO 4G Android Development] ms79723:
Well...Ziggy would be kinda right but fully wrong..Can't cause your battery to explode. Mainly because, the phone itself is on. One thing that NOBODY has bothered to think about is that fact..and thats just sad. How can you overcharge a battery that is still using power? Overcharging would cause the battery to explode...but thats straight up impossible in this case. There have been people using this since day one and no problems. There hasnt even been any overheating..I pick up my phone in the morning and its straight cold...but meh, its w/e. Nobody's forcing them to add/use this

And whats goin on folks? Aint been around that much in this thread as y'all can see. I've been doing nothing but studying for premed and playing Black Ops...and working haha. What I miss?

Side note: I read something about how someone said the SBC messed up their phone...it was in the general forum. Well, thats not possible. There are sometimes when I would connect my phone to the charger and the charger wouldnt turn on. Thats probably what happened. And when that happens, the battery discharges like crazy which would cause the battery to drain completely. Thats probably what had happened.
[EVO 4G Android Development] okaytran:
i know it says in op that it works with all extended batteries, but i was just wondering if anyone has tried it with the ebay 3000 or 3500 mah batteries. how we're results?
[EVO 4G Android Development] LuvThyMetal:
I guess so lol. My phone is leet!
[EVO 4G Android Development] dahauss:
still I ask.... Difference between trickle and bump kernels. is one safer then the other.. Better? One over the other better for people who use phone while plugged in?

there appears to be only one bump kernel and looks like I might be the only one testing it. Anyone?
[EVO 4G Android Development] ms79723:
well the v7 kernels blow the v8 out the water (imo). Trickle charging seems to be the way to go for me. Um as for safer...v8 probably would probably be safer.
[EVO 4G Android Development] Anon9mouz:
So is the htc kernel #15 trickle charge? And how good is it being pretty much a stock kernel vs a custom kernel like nets 4.2.2?
[EVO 4G Android Development] godfirst:
So would you recommend your v7 over savage aosp kernel? I'm currently running cyn 6.1.2. With savage aosp 1.5.2 kernel.
[EVO 4G Android Development] thenewguy821:
Just to end a bit of the confusion, could you explain how your bump charge kernel differs from the phones "standard" bump charge? There is great detail on how the trickle works, but little to no info on the bump method you use.

Thanks
[EVO 4G Android Development] lovethyEVO:
Taken this morning.

HTC #15 with smartass governor, sbc v7 (trickle), no setcpu, 30% screen brightness, 2 5 minute phone calls, 3 texts, 1 game sudoku, angry birds for 5 minutes, and web browsing for about 10 minutes on 4g. (I was on wifi when I took the shots so I can upload the files to dropbox). This is with the seidio 3500.

It finally dropped to 99 right after I took these pics. I would take a shot of my uptime/awake time but my phone hasn't been rebooted in two days. I'm estimating with the 3 hour uptime I had at least 30 minutes of screen on time. All I know is I'm finally getting my seidio charged in the phone as opposed to always using the external wall charger.
[EVO 4G Android Development] cheebahawk:
Quick question, does SBC for Netarchy's CFS More Aggressive 4.2.1 (aka 131) 131.zip (2.91 MB) trickle charge?

I tried it out yesterday because a lot of people are raving about how great the battery life is on the 131. I have to admit it was excellent with moderate usage (at least for me personally) the phone went 13 hrs and battery was at 47% which is pretty good.

But I plugged it into the charger last night and this morning upon taking it off the charger and brief web browsing, the battery dropped rapidly to 92%. This is on par with how the battery would discharge, before I stumbled upon this thread. The 4.1.9 more havs trickle charge version would not display this rapid discharge when I had it installed for several days previously.
[EVO 4G Android Development] Hisma:
is there any people that have gotten worse performance with these?

i have a 3500mAh battery, and i installed this kernel. I cannot make it through a full day without charging now on moderate use. I used to easily get it through a full day previously.

Also, the 1st 10-15% drain rapidly. This seems to be exactly the same as it was before.

I used the less agressive CFS, and did a full wipe + davlik before install.
[EVO 4G Android Development] mrwicked:
When I charge my phone over night with the phone off and when I turn it on in the morning the battery is anywhere from 92 - 95%. If I leave the phone on and charge it will be at 100% in the morning and stay there for a couple hrs. Any reason why this would happen with the phone off while charging? I am using no havs version.

Thanks
