[Nexus 4 General] grkn:
A lot of people say that overclocking the Nexus 4 is useless as it's so fast to begin with, but that turns out to be false, yes, it's useless for making e.g. games run smoother, as they all already do, but it's very useful for reducing loading times, and it turns out that the % of time saved is close to the % of increased clock speed.

My setup: Nexus 4, franco.Kernel updater v9.3.3, Franco Kernel #666, Jelly Bean 4.2.2 JDQ39, Governor Interactive. Angry pigs HD 1.1.0 app loading. Fresh reboot for each speed. I did three measurements for each clock speed and left voltages at Franco's defaults. I would suggest looking into the undervolting threads to figure out how low you can go with voltages, undervolting is good underclocking is usually not.

1026 Mhz 1025mV default Franco

15.4s

15.9s

15.7s

1512 MHz 1150 mV default Franco

11.5s

11.3s

11.3s

1620 MHz 1175mV default Franco

11.1s

10.6s

10.6s

1674 MHz 1175mV default Franco

10.3s

10.6s

10.7s

1728 MHz 1200mV default Franco

10.5s

10.3s

10.3s

Conclusion

12.5% faster clock speed = 8.85% faster load time, which means increasing clock speed is 70% effective at reducing load time going from 1512 Mhz and upwards.

40% faster clock speed = 35% faster load time, meaning that people who think running their device at 1026 Mhz is as good as 1512 Mhz are wrong. Nearly doubling clock speed nearly halfens load time.

The reduction in loading time is reduced a bit as you reach higher frequencies, but it's still 70% effective so every extra Mhz helps cut down the wait. Overclocking the Nexus 4 is meaningless in terms of increasing smoothness IN APP, but meaningful in reducing load times significantly and in increasing the responsiveness of your system.

please tell me for saving the battery and still maintaining a little smoothness

the settings to use

i use faux123 kernel.. i just need the voltage,cpu clock n governer settings
[Nexus 4 General] simms22:
so overclocking makes things faster.. really? who would have thunk. and you just found this out? :p
[Nexus 4 General] zakoo2:
my brother uses a galaxy s3, and after using it for a few months he tried my n4... he was amused how fast things open and how smooth everything was, and it was all stock frequencies. i think it makes no sense overclocking this beast, it is already fast enough. +/- a few seconds doesnt make that much of a difference but drains the battery significantly more. just sayin'.
[Nexus 4 General] alen1901:
Sorry but little OC can help you save more battery in day to day usage. (If you are not playing only games on your phone). :)

[Nexus 4 General] zakoo2:
not according to my experiences, and i did play with oc/uc and voltage quite a bit. i always ended up going back to stock on the n4 (not on my old motodefy though) because of the drainage.
[Nexus 4 General] Nuu~:
So, a 50% increase in clock cycles pushes the performance by a bit.

Who would've thought...?
[Nexus 4 General] crypticclash:
well that's normal, overclocking = more power draining, more speed; just like with CPU or ram on pc, no rocket science here.
[Nexus 4 General] sigma392:
OC? Don't you mean Downclocking or Undervolting?
[Nexus 4 General] gohan040:
Nope , also OC can (in theory) improve battery life because the CPU finishes its task faster.

a pigeon delivered this message.... ** your welcome **
[Nexus 4 General] sigma392:
But er... Wouldn't it would theoretically need more power and therefore generating more heat than stock frequencies which in turn will have a negative effect on battery life?
[Nexus 4 General] compuw22c:
It REALLY depends. I'd say most day-to-day usage, an overclock can actually help save battery by 'racing' to sleep (hurry up, finish, drop to deep sleep on cpu AND radio). I think being on 3g makes it even more pronounced because you're letting the radio drop back down to a lower power state as well as the CPU. So if you need to quickly open an email attachment, and cpu is the limiter, it can help it finish, get off the network, and back to idle state faster and save some battery. Now if you go on running benchmarks instead where you just keep throwing more work at it that's a seriously different story. There is also a point of diminishing returns (usually 1 or 2 steps before the absolute limit, in our case about 1670mhz) but in general, a moderate overclock can help.
[Nexus 4 General] gohan040:
I agree with u, but remember its a theory.. U finish faster so the time it uses more power is less....

^^Look at the post above me, he got a good example^^

The best of both worlds (if your phone is capable to do this) is when u UV and OC. U would use less power on a higher frequency. Win-win in theory.

But I know what u mean and its hard to believe, but I think that's what [MENTION=2500855]alan1901[/MENTION] wanted to say.

a pigeon delivered this message.... ** your welcome **
[Nexus 4 General] Danny.ns:
If you are lucky, you can overclock using STOCK voltage for the maximum clock.

IE, i see many undervolting their phones by alot. I would just try 1150mV (default voltage for 1.5ghz) for your highest speed (OC as high as you can with this voltage), which means you are not using more power, but still making your phone faster.

Haven't tried on mine, but say 1.6-1.7ghz should be possible with 1150mV for a few at least.
[Nexus 4 General] alen1901:
I said little OC. Example. Stock cpu clock is 1000mhz and 1000mv. Now, you OC your phone to 1200,1300mhz without changing voltage, or by increasing it a little bit(+25, +50mv, to make phone stable), it will use higher cpu frequency with the same voltage like on lower frequency or with a little higher voltage. So it would finish tasks faster, going to idle faster without getting any heat and give you more battery. On my nexus s and galaxy s3, galaxy s2, i tested it, and it helped (about 30min more screen on time for me). But if you play games a lot and doing some heavy tasks then underclock and undervolt are best for you. But on that beast of phone, i woldnt underclock it beyond 1.2, 1.3, not sure what frequencies are there. If you UC that phone a lot, you can easyly go with some weaker phone. :D

[Galaxy S II Q&A, Help & Troubleshooting] ennayhtac:
I know there has been a million posts about this issue and I tried all the solutions. Different roms and kernels, factory resets, changing usb, battery calibrations through different methods all with no effect. In frustration I was ready to toss my s2 in the garbage but before I did I decided to try something else (links below) since I figured I had nothing to lose.

It works!! for me anyway. I removed the IC. Didn't replace just removed and my phone now works perfectly. Charges, doesnt overheat. I was reaching battery temps of 80C within a few minutes of turning the phone on before. It was even overheating while turned off! No more warnings or charging paused. So if you have nothing to lose and are ready to toss your S2 like me try this.

[Galaxy S II Q&A, Help & Troubleshooting] droiduzr2:
When I was on ICS my phone ran without any problems.

I can't really remember but I think I had installed an app and it started making my phone go crazy. So I went to AOKP JB 4.2.2 and started having the high heat problem again.

So I removed an app that I had Vault and set playstore to update over wifi only.

I put the Siyah kernel. I did flash a few other modems and I had the same problem. I flashed current modem and all is fine.

Wipe your cache and dalvik cache too.

Try downloading your modem file again.

All I can say is that my battery can now last 3days (in 2g mode no data) but when I do turn on data it does not suck my battery down in 15 minutes.

*I did click on HSDP option and then turned it back on and off and back on again.

1. I would start with a clean basic ROM. Don't just wipe but format everything 2 times.

2. try different modems (I think this is where the problem is)

3. new kernel or different kernel

This phone is working great now.

Like I said tried everything. This fixed mine. Just sharing for others who have also tried everything. I did check the capacitor in question was the source of my problem first and there was extreme heat coming from it.

The "startup wizard" referenced is probably the Google Apps as it thinks it is a new installation, but cannot complete it.

Here's what I did, and it worked. I located the latest Gapps for Cyanogenmod 10.1 on this site, copied the .zip file to a micro-SD card and rebooted the Nook back into the Cyanogenmod booter/recovery menu.

I then chose to "install zip from SD card", located the Gapps zip and loaded it.

I then rebooted and let Gapps complete it's initial startup wizard.

All done, no issues.

Hope this helps.

I looked at the new OTA update...

It has some new stuff that I am fairly confident was put in place to avert the bootloader unlocking...

Here is the OTA: https://dl.dropboxusercontent.com/u/31360541/S4/2400258.zip

Here is its contents:

You will notice it has a new aboot and a new tz.

They are either unlocking the bootloader or locking it down more...

[AT&T Samsung Galaxy S 4 General] lessthanzach:
Hey man. Maybe you wouldn't mind posting your core.odex found in system/framework before you do the update? I used a systemui.apk mod that apparently changed this core.odex file enough to change it's sha1 checksum. Now that the checksum is jacked up - according to the recovery log found in /cache/recovery - the update fails. I've already reverted the systemui but the core.odex is apparently not moving. Hoping to push just that one file back to avoid having to odin back at this stage. The sha1's I'm looking for end in either 0322 or b90d. Anyways, if it's too much of a pain, no worries. It may end up softbricking my phone in the process for all I know. Just trying to avoid having to relink all my external sd card games again. :)

Edit: Downloaded stock firmware. Can't figure out how to find any of the directories to extract the appropriate app. Well, the decision is to either exchange device, or take everyone's word that the update is that good and gets rid of the lag.

Is there any way to modify the ota or is everything signed and secured all nice nice.

My thought was to pull the aboot and .mdn files from the odin packages linked here http://xdaforums.com/showthread.php?t=2261573 and put them in the ota zip then revert the name to a cfg file and replace in the correct directory and proceed with the OTA.

There are a lot of tweaks and patches which users are reporting to be a great enhancement to the device performance.

Just some curious thoughts if this will break the ota or not, since the replaced files will still be officially released ones, just from a previous update.

maybe lead to a way people can update but keep original boot chain to not destroy the possibility of a unlock

Try manually setting the time and date on your phone to the future
[AT&T Samsung Galaxy S 4 General] eak1080:
1. Another way to freeze the update and all future ones is to go into Titanium Backup and wipe data for AT&T Software update V42_1_1303_5_1 and then freeze it (assuming you have TB pro, otherwise the OP method works fine).

2. Also for those having the update fail for whatever reason, what fixed it for me was going into TB and wiping data for the AT&T Software update V42_1_1303_5_1.

So: I have been reading of this OTA Update and got the notification on the phone. As I was at work I decided to wait till tonight to block it then wait until further information developed.

Lo and behold: I hear my phone reboot in my pocket and when I looked at it the update was in progress. I was a bit pissed.

Is this expected behaviour?:confused: Force the phone to restart and do the update?:mad: I am not so sure that I like that idea.

In any case: Root was gone... although SuperSU was still there. The custom icon returned.

When I got home I uninstalled SuperSu, rebooted, and then re-ran the ROOT and Remove Custom Icon Process: all is back as it was.

Let's hope that the bootloader is not further secured.
