Hi I've been looking around to find good kernals while running cyanogen mod 7 rc4. Some of the kernals I install like netatchy gives the screen a weird flickering. Can someone suggest a good kernal that's overclockable and stable. Thanks
Netarcys kernel really isn't for cm7 that's probably why its flickering. You should try savage zens latest sbc or non sbc kernel or tiamats sbc kernel both are pretty good. I'm running the tiamat sbc 3.3.4(great battery life) and I'm pretty happy with it.
Tiamat link. Be sure to get the evo version because he does kernels for the incredible also.

In a nutshell, sbc is a method of charging that allows you to "fully"(trickle) charge your battery. Normal kernels really only let you charge to about 90% for safety measures; while sbc lets you fully charge letting your battery completely fill. There's a few threads that talk about it if you search around to get more "details". I've been using them for months without any problems whatsoever. Good luck
Honestly I get great performance out of the stock kernel.

That happens to me sometimes but not all the time. I believe that's still a problem with cm7 in general though. For best results I recommended going to settings/ cyanogenmod settings/ performance/CPU settings then use the "smart ass" governor. It has provided me with the best overall battery/performance. I also have my min freq at 245 and max freq at 1152.
Those are also my settings, I've discovered my evo can't go beyond 1.15ghz without locking up. I've been trying to get to 1.2 but no go

I don't really put so much stock in scores anymore they don't mean anything to be honest. Dirk used to be a score whore but I just removed the apps so I wouldn't worry about it anymore. I came to terms that my scores won't go much higher then what they already were. Just ran 40 mflops and 1220 bench.
Yeah I just like the braging rights, hopefully they can figure how to overclock the gpu soon tho

Bragging rights how's this for bragging rights; my 12 year old cousin has a tmobile g2(newer processor) which is stock clocked at only 800mhz. His phone scores a 60 on linpack and over 1500 on benchmark and its not even rooted lol. This is why I don't care about scores anymore
I just died a little inside :/ lol I wanna upgrade to the evo 3d soon tho and that's a dual core

I just wanna correct this misconception because it led me astray and it took a good amount of research to realize this was wrong.
All kernels will charge the phone to 100%. That's not an issue. What happens is, once they are charged to 100%, they start draining battery again, and coupled with the fact that li-ions inherently lose charge over time, and the fact that most people haven't conditioned their battery's memory by properly charging it, by the time you pull your phone off the charger it's already lost that 10% (give or take).
Trickle charging hopes to fix this by "trickling" a small charge into the battery constantly once it hits 100%, to compensate for discharge, so that it stays at 100%. The problem with this is, it pushes a current through the battery constantly, and that tends to shorten the life of lithium-ion batteries over time. You may get better immediate battery life off the charger, but you'll kill your battery quicker. Come months from now, your battery life isn't going to be what it should, whether you notice it or not.
If you want to minimize the discharge, you can take a couple safer steps:
- Condition your battery. Charge it to a true 100%. This will mean turning the phone off and on a few times while it's on the charger to make sure it's actually at 100%. Then completely discharge it until the phone cannot turn back on. Do this a couple times in a row, and repeat every month or so. This conditions your li-ion battery's internal charging memory so it knows its true charge potential.
- Charge your phone while it's off. It won't drain nearly as much battery this way, so when you're ready to take it off the charger it'll be much fresher.
- Avoid prolonged charging and continuous charging, because it can confuse the li-ion's internal charging memory. Rather than re-charging it when it hits 60%, let it drain as low as possible before you bother recharging it. Bursts of short charges don't harm the battery, but they make it "forget" how much it can be charged.
In short, SBC kernels are bad for your battery.
---
Also, Savaged-Zen 1.0.1 BFS no-SBC has been the best kernel I've found for the Evo 4G. Granted I haven't had this thing that long and there may be another gem lying around somewhere, but given the popularity of SZ, I doubt it. It's a very good, smooth kernel. It's giving me the best performance of what I've tried (most of the popular ones).
As for CFS vs BFS, flip a coin. Some will swear CFS is smoother, others will swear BFS is supposed to be smoother. BFS gives me more responsiveness personally, but I think it mostly depends on your workload. I keep scarcely-used tasks killed and I don't use widgets, so the lack of many processes may be what makes BFS better for me. Try both and see which feels smoother in daily use.

That's a great plan man. I visited the savage zen kernel thread earlier and some are complaing about their newest build causing charging issues or something along with 100% wake time idk. If you give it a shot use their 1.0.0 instead of the 1.0.1. Just give the kernels about a week and see how well they hold up. Its mainly about personal preference(sbc or non sbc) I'm actually testing the tiamat sbc but I was previously on savage zen. I like to give all kernels a chance(1 or 2 weeks) to see how well my phone performs with them.
Ok well ill just wait till Friday to install a new one then and see how the Zen works out

Alright guys so today is the first time I've had this problem. I'm running warm z twopointtwo 4/7 nightly with chads 12/23. For some odd reason today my phone has been overheating. Now I wasn't able to get an exact temperature read but my guess is somewhere around "way too effing hot" degrees Fahrenheit. I say this because my phone actually got so warm today I almost couldn't touch the screen. I was seriously expecting thermonuclear meltdown! I pulled my battery and let it cool off and all was fine but still it worries me. I wasn't even doing any intense processing. I was only using the xda app and reading some threads. Throughout the day it hasn't got quite that hot but its been running noticeably warmer than usual. My battery also seems to be dieing slightly faster than usual. Now my phone is a certified refurbished less than a month old so I can't imagine this being a matter of my battery starting to die.....so anyone have any input on what could be causing this? Could it be Rom if kernel related?

Nope I have the original battery still in it and everything....I mean it works beautifully outside of a few occasional hiccups here and there but nothing that isn't to be expected.....but the heat problem never happened to me before.....I mean trust me I used to have a crazy overclocked Eris that loved to get hot but never this hot. And I haven't even overclocked my dinc yet....its just kinda odd it was a one time thing but it was almost too hot to touch. It spooked me I legitimately feel like I was very close to processor meltdown.....

Well you are using a "warm" ROM
Just messing with you. I'm running Warm-Z too but Chad's 12/23 kernel won't boot for me so I usually use Lou's #4 or #8, and with them I don't feel heat issues unless I'm charging. I'd say switch kernels. As long as it's a Sense kernel.
Well like I've never flashed kernels before....I'm sure I could figure it out....but none the less this isn't a frequent problem.....that's the only time its happened. I was actually in an area that was in and out of service though.....does bouncing around in service while trying to use 3g require a lot of processing? I can't imagine it would....mebbe the heat came from my cell receiver 0.o
Sent from my Incredible using XDA App
Yeah looking for a signal is apparently pretty battery draining. Still not really sure about the heat issue though.
Sent from my ADR6300 using XDA App
Well I mean if its battery draining that would mean more current through the phone for the battery to drain more rapidly. More current translates into heat in any application. But still the level of heat that was coming out of it was crazy. And I could actually watch my battery decrease fast as hell

Well, I'll give you the link to Lou's #4, and that's a pretty basic kernel. Really it's like flashing a ROM. You go inside your recovery, and ONLY wipe CACHE and Dalvik-Cache. Then flash the Kernel's zip. Then reboot!

What are the real advantages of me flashing this kernel over my current one? Like I don't think it'll help the problems with heat. I'm still interested in that on a side note though. Does it have havs? Cause I hate the fact that I lose ten percent in five minutes after unplug

Some kernels are just better for your phone, and some aren't. I took the time to find a kernel with HAVS that I've used in the past.

This should work fine. Ziggy's a pro.
Will that be compatible with warm z? Like I said I'm not familiar with which roms work with which kernels? And while were at it what the eff is bfs? I think I know what the acronym stands for though I'm not sure.....but I have no idea what bfs and cfs are.

I think it could be the cause of the battery drain but it doesn't seem like it should cause overheating although I could be wrong. Have you had the issue since then or was it just when you were having trouble getting a signal? BFS-Brain **** Scheduler. Linux stuff.

Possibly. Let me explain.
I'm currently running rooted 2.2 and if mine searched for signal, battery gets warm.....really warm. I flashed the radio to 11.19 (Evo) and so far, knocking on wood, my signal search issue has gone away and GPS seems to lock on instantly. I'm also using the 1800 battery from htcexpress dot com.
The only other time my phone got so hot that the amber light started flashing was in the car, charging, running GPS and streaming music at the same time. Battery temp according to my a battery app was 128 degrees F.
128 f isn't too bad....my Orange light didn't even blink that's the thing and i didn't have an app to tell me the exact temp. However I know that if through the entire case my phone is almost too hot to hold then its probably pretty close to processor melt....and that's another good point.....wtf didn't my light blink? It should have but didn't.....hmmm.....but none the less @k_nive if you agree about signal drop causing battery drain then wouldn't my above post make sense? Yanno, more battery drain = more current and more current = more generated heat due to small energy loss through the wires because of total conservation of energy without the phone following total conservation principles? Aka the phone isn't efficient enough to use all the energy supplied to it so it gives off any excess in the form of heat? And thanks about the bfs info!
Sent from my Incredible using XDA App
And on a side note. I read up on bfs. I get it....kinda. I understand the point but what scheduler is used in chads 12/23? And what are the real advantages if bfs for us Android users over any other scheduler?
Sent from my Incredible using XDA App
It does make sense I suppose. Its just something I haven't run into before so its hard to say for sure one way or the other but the increased battery drain could definitely result in more heat especially if you were using GPS or streaming music at the time.
Perhaps your phone didn't hit the temperature that triggers the flashing led? The phone can feel pretty warm without actually being too hot. I would get a battery widget that lets you monitor temp that way you have a more accurate picture of what's going on. As far as Chad's 12/23 kernel, I think it uses cfs as opposed to bfs but I'm not sure, I'd have to check the thread. As I understand it bfs ramps up the processor more for specific apps/processes while cfs is a more balanced scheduler. I don't know much about the differences so feel free to jump in and clarify things!
Sent from my ADR6300 using XDA App
Grrr.....so I thought that the battery temp problem was gone but Damn it if it ain't acting up again.....this time even more odd....the phone was not nearly as hot to the touch and yet my led started blinking the too hot code at me.....so wtf? Like before I almost melt the effing board and I don't get a single blink. This time its slightly warm and I start blinking. My phones losing its mind. I just got juice defender and a battery monitor widget to try and figure out wtf is up.....any more input very welcome!

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...
Sent from my PC36100 using Tapatalk
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.

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?
Hey guys. Been running aokp by ktoonz for a few months but noticed something off today. A huge percentage of battery used by "Phone". Screen shot is attached. I actually barely used my phone at all today.. Though it was roaming a bit due to holiday travel. I figure that wouldn't cause a huge amount of drain though. 2hr and 9min of cpu use of that process and 4min of keep awake... Pretty low keep awake but high cpu use, right?
Any ideas? Thanks!

According to my dash clock widget and my toasted face, my battery reaches some super high temps. Just hit 131° F. Which has prompted me to post this since this is the hottest I have seen or felt.
Does this usually point to a battery issue, I know the galaxy s2 I had was prone to battery issues. Or possible hardware issue?
Thanks everyone for your thoughts!

Yup. As soon as I plug in the charger it goes up to about 104°. After 30 secs or so of use, its above 120° and stops charging due to overheating. This has just started happening as of late. Happens on both my stock and extended batteries.
Any ideas?

Some ROMs run very hot for some reason. Are you on Carbon? It seems to be the king of white-hot temperatures. Under clocking and undervolting should ease the heat a little bit, but I'm not sure what else you can do.

maybe kernel problem.
flash other kernel (fancy), wipe cache-dalvik and fix permissions.
with fancy kernel; charger in deep sleep battery:80° F, cpu 90° F. hardcore(benchmark) battery:95° F, cpu:120° F.
with ak kernel cpu:160° F and battery:120° F
For me the stock rom and aospa have been the coolest literally with AK you can set up the kernel in any way you like speed demon that eats thru batt. and runs hot OR cool and smooth thats easy on the batt. and temp.
You should check with another batt. :-S it might be possible that your batt. is borked
