What is a safe level to over clock?

Hi all,
I am using a rooted n7.
I have over clocked my galaxy s2 to 1.5ghz before, but I am not sure what is a safe level to over clock the n7 to.
What is a is is for battery life and performance?
And which kernel do u guys recommend
?
Thanks in advance

I run trinity kernel on my Gnex and N7 and on my N7 I keep it stock speeds because I've seen no reason to realistically OC it. Most of the improvements I see are from the kernel software changes over stock. You can OC to 1.6 safely but I'm not sure of the power usage difference but I'm pretty sure the loss in power isn't worth the gain from OCing.

I have mine at 1.6 just for the hell of it, I get a good 4 or 5 hours of continuous usage out of it.

For the benefit of the community, can you tell us any major changes at 1.6 GHz?
Is there anything noticeably faster?

Hi, I have a related question but can't post since I'm new.
Using the glazed rom which i like but it apparently has gpu overclock. I would like to know how to adjust that back to stock setting or at least see what it currently is. I found the CPU section but there is no gpu I can see.
Is there a tool I can use?
Sorry for the hijack...at least its sort of on topic

IMO over clocking is a gimmick, its the kernel build

My thoughts exactly. I play some light games and web browse on my Nexus 7.
For those purposes, my Nexus 7 is already extremely fast, so I don't think I would be able to notice if it was over clocked.
But I guess it depends, maybe there's a big difference when running GPU heavy games.

I have OC mine upto 1640 MHz for bench marking alone for half and hour or probably more and it went fine although the tablet was getting warmer more than usual.

Hi,
I decided to flash trinity kernel.
I am currently OC to 1.5yghz, is that a safe level to keep it at full time? Or can that burn the cpu out?
Thanks again

Edit,
I over clocked my galaxy s2 ages ago, and I noticed a huge difference in performance.
So that is why I want to over clock my n7 too lol

there is no such thing as a safe overclock. overclocking, by nature, carries some risk. that said, i havent seen anyone brick their device from overclocking.

Just wondering
Why do you feel the need to OC?

I go to 1.6 but use the Trinity App to go back to stock when OC not needed
Sent from my GT-I9300 using xda app-developers app

I have not over clocked the Nexus 7 yet but one way to test your devices max is to use setcpu. Make sure you do not have "set on boot" option selected. Then step up your cpu. If your cpu can not handle the over clock it will force restart. If you do not have the set at boot selected it will revert back to the last good state on restart.
Each device is different on what it can handle for over clock.

To be honest I doubt you'll notice much increase from oc the CPU since the CPU already is so powerful nothing pushes it to max really.
Only thing worth overclocking is GPU really. And at that, your not going to notice a difference unless your playing some intense games.

Epsxe/Fpse Battery drain

So actually I am a big fan of ps one games and I can't resist to not play ps1 games on my phone.
Well I am worrying about there battery drain here.
After playing a game on my epsxe and fpse(about 35 minutes) I go from 100% down to 69%
Is it normal? or not?
(also my phone heats up after this amount of time)

Most likely you need to change CPU settings, including voltage.

I am on stock android(rooted)
Can you recommend me a good Rom-Kernel combo ?
Cause this is my first android experince, and I am not sure what the best rom is for a beginner like me is .
I also do not want to damage my phone by tweeking with the cpu and voltage settings.
Should I wait maybe for stable roms? Cause I see alot of nightlies roms.
Also I am not familiar with the term "milestone rom"
Thanks in advance.

Any of the custom kernels should last a bit longer than stock. I use IntersectRaven's kernel. I have fpse but haven't gotten around to putting any iso's on here yet so I'm sorry I can't give any report. You could also try lowering the brightness while you play, and turning off data or just enabling airplane mode if you don't mind not being able top receive calls or texts while you play.

You can stick with stock ROM rooted but you can under clock it. The emulator doesn't need a lot of power, I use yo use it on my 600mhz phone so it should be fine with the nexus. Also stock rooted is the most stable.

Or keep the phone plugged charging while playing, this phone is a battery hog, i mean am not trying to generalize, but seems like some people try to multitask all day long on a mobile device with no removable battery, i mean really, think about a gadget trying to process console games, web, content, gps, screen activity, all at the same time, come on people at the end this is a phone not an alienwarelike or multitasking wireless gaming console

Should I use SetCpu in order to under clock it?
Also I heard many positive things about the franco kernel, is it worth giving a shot?

I haven't tried it personally but, you should still give it a shot. And setcpu is fine.

Most custom kernels lag more than the stock kernel.
If you want to go the custom kernel route for (at the moment) better battery life, go either CyanogenMod(the one included in their ROM) or Franco.

Flashing a Kernel - Question

Hey guys,
So I've got a rooted Nexus 4 and it does not have any custom ROM installed. I'm running the stock OS and it's smooth and functions without any problems. The battery life of the device is okay but I would definitely like it to be more efficient. The franco.kernel is praised all over the web, especially here at XDA and I definitely want to use it. I'm wondering what the easiest way to flash it on there would be. I've seen that fastboot
is one way to do it but I'm not sure on how to do that. Any help is appreciated Also, is any sort of wipe involved when flashing a kernel? Backing up is a mission and I've had terrible experiences restoring any backed up data so if avoiding one is possible, that'd be great. Thanks in advance!

All you have to do is flash it in recovery. Wiping cache won't do any harm either.
When I also just got my N4, the first thing I did was flash franco.Kernel because I didn't know better. It's definitely not the best kernel out if you look at our section. My favorite kernel is Trinity Four. Battery life is great, the thread atmosphere is awesome (we don't just talk about the kernel. Take a look and see) and the kernel is super stable.

I beg to differ. Franco's kernel has been the best in my opinion. I have tried all kinds of kernels and they were either hot or a battery hog. Franco's kernel is the most ideal for me
Everyone has a subjective opinion on every kernel so it depends on you.

Thanks for the replies guys! My most primary concern is battery life. I doubt I'll be using the kernel for anything else really. Any idea on how long it takes for a kernel to be fully stable and release with updates once in a while? I know a lot of people like one of Franco's builds specifically, which is a nightly.

I think trinity kernel is one of the best out there and very stable and updates are very fast.

Hey! Which version are you using? Also, do you find that the Play Store updater is necessary?

This time around I have just been using the stable releases. R53 is what I am using right now.
I don't play with the voltages or anything, just flash the .zip and use as normal. With all my android phones, instability happens when playing with the under-voltage settings. It just isn't worth it to me to squeeze out that extra 20 minutes of battery life.
I would only use the play store app if I planned on messing with the colors or regularly flashing nightlies.

Thank you very much, I'll probably flash r53 tonight and see how things go after a few days of use I bought Franco's Display Control app so I'm pretty sure I won't be needing the updater for colour controls

You don't need to wipe anything before flashing Franco's kernel. Wiping cache/dalvik isn't needed (that's a ROM thing add opposed to a kernel thing).

Ah okay good to know, thanks!

I used franco's kernel over the past weeks but I many wakelocks. Then I tried harsh's and got average (kernel!) wakelocks at 1-1.5%. I UV so my phone is pretty colder compared to franco's. With faux's I could make me some bacon

Hey so I'm hoping someone here can help. I did an nandroid backup on my phone, then flashed franco's kernel. My phone will not turn on anymore, every time I try to hold the power button down or boot into bootloader, the LED just flashes red.
Am I screwed?

The kernel isn't the problem. What you have to do is remove the battery and plug it back in. It's as easy as that.

I somehow got it back working without opening the device.
Try to long press the power button or the power button and volume down.

[Q] Bought it, now what?

Hi everyone,
I posted a few months back whether I should buy a Nex 4 or not. Now that I did, I have another Q.
With my old Galaxy S, i HAD to root and install ROMs cuz it was reaaaally slow. Now, with the Nex 4, it's super fast that I'm not even thinking about ROMing it any time soon. However, I was wondering about rooting it. Does rooting affect the speed? it made my GS faster. Will it do the same for the Nexus?
Thanks.

Just rooting won't actually do anything but installing the right apps will. Of course if you overclock it it will get faster, but personally I underclock it to save battery. I'd say it is definitely worth rooting it. You never know you might feel like installing a ROM later so it can't hurt to root now. Basically everything rooting did to your GS it will do to your N4 but the nexus is already fast.

I'd suggest a kernel change at least. The stock kernel made my phone very hot sometimes and the battery life sucked.

Unlock bootloader, root, start modding and theming, or flash custom rom, have fun, and ignore all the idiot trolls here.

To each his own.

I rooted my Gnex the first day I got it. Although I plan on staying stock for awhile on the N4 since my favorite custom rom (CM) seems to be a bit glitchly atm.

What I did for an while was run stock-rooted for a bit. I turned ALL animations in Dev Options to .5 and my phone was flying! Quick to menus, opening and closing apps, and saving RAM. Battery life was great considering I'm a stickler when it comes to WiFi and Data toggled. Than I would run either PACman or Paranoid Android. Both were fluid experiences. But nothing beat Stock Rooted speeds.
It just matters what you're looking for. Try ROMs out, there's plenty of them out there! Good luck and happy rooting!

The only kernel adjustments were to the governor and scheduler (using smartass and sio, no alterations to either). I just tried using the rescan media disabler apk to see if maybe my media was causing the phone to run hot. It seemed to be the only thing going in the background.

Usually the heat starts when I am using the phone, which is usually browsing the internet or reading up on sports news. Screen off or charging I have been OK so far. As far as the battery, it appears to be in good physical condition. I also have 2 OEM batteries by Anker that experience the same issue. So far so good, though - been using the phone moderately since the last shut down earlier today and it seems ok at this moment.

if it heats up really bad again try underclocking a step and see if that helps.....phone might be getting hot because your chip is poorly coated and the higher frequiencies are heating it up enough to shut the device down. you may have to underclock by one or 2 steps to ensure its not a consistent issue.....worth a shot anyways. unless you do high graphic gaming and multitask with 8 apps at once your really dont need the higher clock speeds anyways.

Good idea, hopefully I won't need to! Appreciate the feedback.

If you just got this phone Friday then I would return to stock, run triangle away and exchange it. What you describe isn't normal, why take a chance and get stuck with a bad phone when you are within the exchange window.

Seriously guys, your S4 doesn't heat up at all???
I'm back to 100% stock everything (kernel, rom) and running this for a couple weeks. I've completed several factory resets and whatnot as well through those weeks. I know my install was clean as could be.
Now, my phone gets hot at seemingly random times. sometimes playing games, for sure while navigating with GPS and sometimes when its just sitting there. I monitor things with Better Battery Stats and keep an eye on the CPU Spy. I'm achieving deep sleep most often. Some of this is caused by the god awful Sprint service here and the constant search for signal, but I was hoping that this wouldn't get as hot as the S3.
so, should I seek a refurb from Sprint? I have the insurance. I am just afraid that a refurb would do me no better.
My biggest gripes are heating up occasionally, WiFi disconnect issues. I hope 4.3 can help some of these.
