im currently on icbinb kh1 with the gingerbread enhancers. im interested in overclocking but i want better battery life. the undervolt settings in the gingerbread enhancer has worked great for me. does anybody have a setup that they feels increases performance while offering better battery?
the best solution is factory clock settings. If you want performance, you're going to sacrifice battery. If you want battery, you're going to sacrifice performance. Think of it as a sliding scale.
thats not necessarily true. i overclock at 1.3 on my phone and it lasts about 3 days with normal use.
if you have bali uv installed, its already undervolted, so you can overclock at higher frequencies. with the right things in place, there is no big negative tradeoff.
look in the icbinb thread for anyone else overclocking. i no longer undervolt using the given values cause it caused freezing. i use stock with a level 0 of 1.3. works great. battery lasts forever. no complaints.

I use the same settings on ICBINB but on 1.3 I only get about 13-15 hours of battery life without charging. Guess its just different for each person based on usage.
i like 1.2 uv fast and pretty good on life.
frequency=1200000, 800000, 400000, 200000, 100000
core_voltage=1230, 1080, 1005, 905, 855
int_voltage=1090, 1050, 1000, 980, 950
scaling_governor=ondemand
thanks i just wanted people to chime in with setting that worked for them, try a couple out

Hey all just a quick question, obviously with the 1.8 OC on the Inspire this thing is blazing. But what is the battery life like at these OC's or even the voltage differences between stock 1 ghz 1.3 and say 1.8? I really just don't want to get the phone and OC it to keep it fast/smooth but have my battery last like 5 hours. So any insight about how much OCing affects battery life would be appreciated. Thanks!

well overclocking will drain your battery down faster. I would install setcpu from the market and set you clock speeds really low with the screen is off. This will help save battery when the phone is not in use.
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.
I know overclocking is all the rage for more performance. I myself would prefer the gains of overclocking (probably wouldn't be 1.7 ghz atm since that is the performance based kernal, but 1.5 ghz might be doable) with a combination of undervolting for longer battery life.
I know when I was considering a viewsonic gtablet, that most of the kernals that overclocked also undervolted at the same time (how much depended on the kernal and how much of an overclock too).
Advantages to overclocking are pretty obvious, more performance. Undervolting makes the processor (this case SOI) run off of less power, thus more battery life (can be significant if undervolted enough) and less heat, which translates into a tablet that potential has a longer life (heat overtime wears away at life of SOI/processors and sometimes other components), plus much lower risk than overclocking. I undervolt all my laptops, I mostly get my laptop with 3 hour battery life to 3 hr 30min or even 3 hr 45 min on a moderate undervolt. A little undervolting could take this tablet from 8-9 hours to possible 11-12 hours of battery life (plus a little overclock included will add some performance too).
Do any of the present kernals out there try this? If not, I would like to make a request for such a kernal.
Undervolting might cause the TP to be unstable and crash.

it would need to be done in small increments just like overclocking. Same methods are used undervolting as you would overclock. Yes they could both cause instability, if you double the clock speed or cut the voltage in half, it takes time to know the limit of the SOI by using small increments.
You will need to your favorite custom kernel and adjust the volts yourself using Govnah.
But then I also was reading on forums on webosbuzz and you can have screen wake issues to with undervolting

Really? If that is true, I wonder how undervolting would cause that.
The webos-internals-testing kernels include initial experiments with undervolting.
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.

I'm looking for the fasted NS4G Rom/Kernel Combo...
I'm looking for something slim, but with Gapps. But will stay fast and be good on batter. (I know its a lot to ask). But it just feels like my phone is slowing to a crawl...I'm not looking to play any games on my phone (I have a N7 for that), just the basics, occasionally look things up on the web, text, call. I just want a fluid, fast experience.
I'm currently on the newest RasBeanJelly, willing to move or maybe just recommend me a Kernel, because I'm currently using stock.
Any help/tips/recommendations would be great!
Thanks.
CodeNameAndroid 3.6.6 with AIR Kernel is the fastest my phone has ever been. It is different for every handset and user though. Everyone uses their phone differently, and every handset isn't able to overclock, undervolt, or both at once, depending on how much better than the "standard" your specific chip happens to be.
I did overclock mine up to 1200mhz from the stock 1000mhz, but I was able to undervolt it to stock 1000mhz voltage (I believe it was 1250mv) at 1200mhz and remain stable with Ondemandx and Deadline. Was also able to knock -25 to -50mv's off of 1000 and 800mhz also and still stayed stable. I did get good battery life on that ROM too, but hard to say how much since the battery in mine is all but ruined (my kids play on it all the time so it's been charged like twice a day for a year and a half)
I know that overclocking/undervolting results vary from handset to handset depending on how well binned your chip is. In my experience, these things are almost always stable at 1200mhz with 1300mv with a ROM/Kernel combo that plays nice together. That is a 20% increase in speed with only a 3% - 4% increase in power. Well worth it IMO. I also loved Blackbean with Marmite and Crossbones with Matr1x. YMMV
Blackbean is my favorite looking, CNA was the best performing for me, and I've always liked Crossbones because it has always ran rock-solid on my NS4G with no reboots or lockups. Seems like I can always overclock higher and remain stable on Crossbones with Matr1x or AIR also (but it kills the battery so I stick to around 1200 because I dont even notice a difference)
Cm10 with marmite kernel
Slim 3.0 all the way. Its already got a great kernel!
