Overcloking

Is anyone else having an issue with custom kernels? My Tbolt only seems to run on the stock kernel/voltage. When I flash an oc kernel sometimes it will load and then freeze the system.

All phones are NOT created equally. Your phone may just not be able to handle it while others could.

I realize every cpu used is not the same and can't handle being overclocked to the max, but come on, I can't overclock it at all without it freezing shortly after the Rom starting. Don't you think that's a little out of the ordinary?

I seem to be able to run speeds up to 1.8 or so without issues. Something I'm noticing is even with higher speeds, being on the smart-ass setting still isn't baby butt smooth consistently. I know they are still fine tuning it. I can run at a much lower clock speed while set to on-demand and get great results. How it is on battery life? Still testing. I'm using Ziggy's latest from this evening, BFS.

Yeah that does sound kinda sketchy. Which kernels have you tried? Have you tried running one that wasn't undervolted? I've heard people having issues with the UV kernels.

I know what you mean. I had the 1.2 GHz uv kernel from adrenalyne and the phone ran like crap. What's the point of over clocking if real world results are worse. Smart-Ass would stutter while it was ramping up and gun bros ran like crap until I reverted back to the stock kernel.
I'm hoping somebody makes an OC kernel that isn't under volted.

I'm running Imoseyon's version 3 of the lean kernal, 1.4 ghz, undervolted. it seems much faster and more responsive, and has yet to cause me any problems. Right now I'm running on 20 hours off the charger with 45% battery life left (extended battery, so assuming stock would last around 9 hours).

The only kernel that works for me is adrenaline's 2.6.32.21 battery is life kernel. I've tried his other kernels, imoseyon's lean kernels, and a few others all with the same result of freezing up the Tbolt.

Have you tried adrenalynes newest kernel? I'm using version 4 right now with no problems.

Yeah, another vote for Adrenalyne's kernels here.
I'm running the version 4c, and it's flawless on my phone. (4b locked up at higher speeds.) But the other tweaks he threw in there kick ass. Louder audio, faster charging and, I think, most significant, a potential fix for the GPS issues a lot of people are experiencing. Granted, mine was not too bad -- I could usually get a lock within a minute or two, but now it's locking in under ten seconds.
Can't quite comment on the battery life yet, but it's probably pretty damn good, especially with a minimal overclock or even staying at 1Ghz.

Running one of Ziggy's...so far so good...

I ran Drod's 1.5 kernel with no problems overclocking. When I switched over to Ziggy's or Adrynalyne's overclock kernels, I am unable to overclock with out my phone freezing and going into constant boot loops. Kinda weird but I have no real need to OC so I just went with Adrynalyne's stock kernel and been fine ever since.

[Q] just got the Nexus S 4G. should i stick with stock?

Hey everyone, i just upgraded to a Nexus S 4G this morning from the ol samsung transform, and i was planning on applying cyanogen but then i messed with the phone a bit, did root and restored a couple of my game apps...it seems to work with very nice speed, only serious issues ive noticed are just with the signal, sensitivity of keyboard, and i havnt had time to see battery life yet..
But i was wondering, since the stock rom is so clean and fast, why are we putting on different roms like cyanogen?
More importantly, as far as kernel, whats the best kernel right now for nexus 4g? im running stock kernel, but naturally and ideally id like even more speed(not sure what id use it for, but always nice), better battery life, and better data signals..
ive been reading about overclocked kernels a little bit and such, so basically im wondering about what you guys would say to all this? should i change rom &/Or kernel? to what? why? does overclocking at 1.4ghz like these kernels say have any negative side effects? things like that.
Thanks for your response!

There are quite a lot of things that can be changed by flashing a custom ROM. Cyanogen is reported to be more responsive than stock android, and a slight improvement on battery life and performance. Also, with other ROMs like MIUI you can completely change the entire GUI basically. The lockscreen becomes changeable by one click in the themes app. I've also noticed a slight improvement in battery life/performance and responsiveness.
Also, with regards to kernels, they add extra features (like voodoo sound, BLN notifications, UV'ing, OC'ing, etc). Now if you're looking to overclock your CPU AND save on battery life then that is probably not going to happen. If you OC the CPU you'll as a result draw more battery power when it reaches it's peak. Hence why I went with the TEUV88 kernel. This kernel undervolts the CPU yet manages to give me the same performance as the stock kernel. It runs extremely nicely and the battery lasts me about 24-30 hours on moderate usage where as before I was getting around 16.
Hope this helps.
Edit:: note that both undervolting and overclocking can be dangerous for any phone. The kernel developers put their kernels through testing though to ensure they are stable enough for most people (I hope anyways). But be aware that it is possible to damage the hardware be either of these methods.

yeah im looking at more undervolting for battery life cause current performance seems great for me as of this point. but i mean cyanogenmod doesnt change much since its built on gingerbread, its just slightly more customized, but on the actual performance side, it is a slight increase? so whats the best kernel for undervolting and still getting stock performance or more? im guessing its the one u just mentioned? cause i saw a voodoo kernel or something on main dev page and itwas undervolted and OCed to 1.4 i think...idk.

Yeah you might be talking about the matr1x kernel. It ocs to 1.44 and is uved also. Plus has voodoo sound, bln and bld. Some people have issues with cm7 and some don't. I really don't like the look of miui so I can't say for it. But I use decks 1.3d with zero issues and matr1x kernel with zero issues along with heavy use 4+ hrs screen time in over 12hrs. Personally running 1.44 your phone will prolly lock up but I run 1.2 non stop no freezes or lockups or reboots. Try them and see qhich ones fit you and what you like.

I'm still on stock with mine and honestly, I don't need anything else... i get 12-15 hours of moderate use and i don't really know what lag is because i never experience it with my phone.

The above posters are correct in everyway. I mean it definitely comes down to preference. I was averaging about 13-15h on my stock kernel/rom but my phone would be basically completely dead.
I switched to TEUV88-rammstein2 (Trinity Undervolted rom). It has Voodoo sound, BLN (backlight notification), and with todays update it has touchwake mod. So as you can see my phone lasted 15h (still with 35% battery left) with 3h of screen on, and 45m of audio streaming, and lots of texting.

[Q] What kernel would you recommend

Okay I'm planning to buy this phone and decided I am going to use CM9, just wondering what kernel I should use stability and performance is key, I don't mind battery life I can cope with charging every night as I do this now with the worlds worst phone (iPhone 3G) fully charged this morning (8:00) now 30% (17:15) all I've used it for is a little browsing and at most 2 and a half hours of music at mid volume and sent a few texts. So to wrap this up what kernel would you recommend stability ranks higher than speed but speed is important battery mind I can cope with as long as it is better than my iPhones :') If anybody already has CM9 post some screen shots :')

either franco or glados will give you the best of all worlds (performance, stability, battery). i'm not partial to either, i just flash whichever was updated more recently.

I'm sticking with Franco's since it's done wonders for me on GB.
Using it on ICS now and it's stable and fast.
Greetz

i haven't try ICS yet, but in GB i suggest FRANCO , it's damn good
about battery , it happens to all smartphones ...
only you thing you can do for hard usage is buy an extra battery or extrenal power , thank god our phone's battery is replaceble not as iPhone which is UNreplaceble...

I like mathkid. I used franco on gingerbread but i feel mathkid 11.5 ics is better on ics

Hmmm, what's it like on the performance & stability side?

i think franco's kernel is good ..

Franco Kernel hands down.
He frequently updates his kernel usually on a weekly basis as of now and contains all of the power saving tweaks (Lazy Govenor, DEEP IDLE, BLX, TouchWake Live OC ... this guy is good) created by the creator of the GlaDOS kernel Ezeekel.
He does not have any debugging tools running in the background (as other kernels do) for optimal performance.

[Q] Battery saver kernel for Sensation

Hi!
Ok, i'm not good in writing especially in english so here we go
From all kernel that has been released lately, which one do you recommend for having the best battery life in term of standby??
My opinion is Sebastian's kernel in ARHD 6.5.1
it gave me mostly 2 hours for 1%
but i have new problem now cause i flash ARHD 6.5.3 and then restore boot from 6.5.1 NAND back up and now my wifi gave me error
(but this is my problem, not yours )
Come on guys, give me your opinion

I'm currently running Hyper NonSense with the default kernel - I think it's Faux that's cooked into the ROM but unsure of this. Between the ROM and the kernel, I'm getting the best battery life I've seen with this phone. Easily have 30-50% left at the end of the day with moderate use; haven't actually benchmarked it more carefully than that.

Any update on this? My sensation doesn't even last a day...

Best kernels right now are Faux kernel
Sebastian FM
Bricked kernel
I myself have found that bricked uses the less battery, but try them yourself and decide which suits your needs.

I'm using Faux right now with HyperNonSense and I would say it's a good balance between battery saving and performance. One thing to keep in mind is that the higher you OC the more juice it'll drain. So far I've always capped my CPU to 1.24Mhz and I've never had an issue with performance. During light use I can get more than 30 hours in a full charge. If it's a moderate use, I'm still able to touch 24 hours. Oh yeah I'm using Anker 1900mAh.

[Q] rom vs kernel in battery life

This is a rather simple question do different roms really have better battery life then others or is it more of the choice of kernel? Do roms effect battery life as much as the choice of kernel? I currently have vipers Rom and just maxed out at 3:20 of screen on time with stock battery with underclocked and undervolted Sebastian kernel and want to no if switching to elegancia Rom would really make a difference in battery at all
Thanks

Hi,
Battery usage is a very subjective matter.
Everyone uses their phones differently,so , judging battery life between people is hard.
Yes , some ROMS are better than others.
Yes, some kernels are better than others.
It is the combination of the right ROM and kernel for you that is going to matter.
And no one can tell you what that is.
Experiment for a couple of days to see how they work.
READ what other people are saying about them in the threads.
OR,
Get a couple of spare batteries,and carry them around with you,and then , power is never a problem.
