I attached picture of synapse below with my current cpu settings and my question is is it good enough for performance and battery saving and can I do it even better?
I have android l with unleashed kernel

only you know as we all use our devices differently. there is no such thing as best setting. since we all use our devices differently, best settings would depend on your usage. thats for performance and for battery.
I would recommend bumping up the screen off frequency one notch because with 500mhz, some music playing applications like tune in radio skip occasionally.

Hello guys,
I'm here to ask for all of your opinions about the cpu Profiles, frequencies and governor.
For screen on I'm currently using 1200mHz on performance, I would like to know if it would save more battery by using on demand governor.
Some months ago I had a discussion with few xda members about this subject. But that was on aurora v4. Now I'm currently on v5 u17. Let me know your opinion. Thanks

To be honest, I've never experienced any benefits of setting cpu profiles for screen on, screen off etc. Your phone will work much more smoothly if you stick as close to the defaults as possible.
I don't use profiles. My min is 245 and max 1200, using on demand governor.
For a while I experimented with profiles, and had bad lag when unlocking the phone, and terrible battery use when screen on.
Independent of profiles, your governor will put your phone into deep sleep when the screen is off anyway.
Do a search for "race to idle" this explains in more detail the benefits of using ondemand as opposed to other governors in terms of battery use etc.
IMHO, Android as a platform would be far better served if people stuck close to the default settings and cpu profiles. Most of the time, any negligible benefits are just placebo.

So according to the race to idle running with performance governor saves battery

In theory yes, but if your cpu is always running at max frequency, ie even when doing nothing, then no.
I have done tests, and my battery always lasts longer using ondemand as opposed to performance, or other governors.

Use interactive/bfq that's the best in my opinion

Does anyone know a stable ROM that can significant increase the battery life on the Nexus 4? Right now I'm stock, and battery life has been terrible and doesn't even last me through the day. It is also very slow to charge on the included charger, but seems to charge faster on a Kindle Fire 1.8A I have.
Thanks!

The custom kernels in the dev section offer decent battery life.
I'm a wifi user mostly and I get @5.5 to 6 hours screen on time with lite gaming and browsing (this site all day lol).. i do Undervolt by a total of 150mV too... I recomend Harsh's kernel personally.
Underclocking the CPU is not worth it imo because it just makes other cores go online quicker when more power is needed... though it may help a small bit.
other usual tips..
use low screen brightness
turn off google now
turn off gps location
only sync stuff you really use, turn other syncs off (i have just gmail,contacts,browser synced)
turn off nfc if not using
make sure to use the open recent apps button and swipe away all apps when putting the phone down for a while (this really helps with stock kernel because of the wakelocks)
edit.. also after a week or so of charges the battery gets better.
Mpdecision is killing the battery. Try Franco kernel or faux.

I'll give Franco kernel a try. Can CyanogenMod increase the battery life in the Nexus 4?

Sorry, no "Best ROM threads"
Closed thread
I've seen a few post on how to undervolt but I'm still not 100% sure how or if I should, I'm guessing it gives a little bit more battery life ? Also what app would be the best to use ? And the best values to apply
ROM: MAKO-JB-MR2

you have to install custom kernel for undervolting.. and it does not give you battery life..it reduces how hot your phone gets..
It can increase battery life actually, not hugely but ARM processors used in phones use a few watts, wattage is calculated as voltage * amperage, less volts going through the lower the wattage, ergo lower power consumption resulting in extended battery life. /rant
OP you will need a kernel that supports UV (pretty much all non stock) and a UV interface, I prefer trickster mod. Look for core voltage and knock it down a step (-25mV). Then stress test / benchmark, if you don't freeze / reboot then you can knock another 25mV off, keep doing this until you get the minimum voltage your phone remains stable (for me 1025mV @ 1.5GHz). You can then set for the options to stick on boot.

So I have a very thought out question now I have a 4 core phone right? Well my battery life is below average and I was wondering if I had all my cores running at once would it balance out battery life? I just need some help from someone who knows about all this and are all cores mandatory?
Sent From My Liberated E970
You can select how many active cores are activated with trickster mod and (necessary!) a kernel that supports this.

I know how to and can with my kernel but I need to know if more cores are activated if the battery life will be better or worse

I would definitely take a look in to what my batter usage is and how to control that before I worry about the cores. Just my two cents.
P.S. I am sorry but I believe the Multi-core in the title is spelled wrong.

More cores active would mean more processing power, and more processing power requires more energy(atleast on the same cpu), so disabling most of your cores would result in better battery life, maybe by a little bit though.
Hahaha I didn't realize it said mulit

useful topic
It seems to me that by disabling cores wont make a difference to your battery life, only to your performance. It doesn't matter if 2 cores work for 5 seconds or 1 core works for 10 seconds, it is practically the same power consumption
Play around
I would say download CPU-Z from the Play Store and look how much Cores are active and which clock they're at.
Then flash a custom Kernel, which lets you control the clock, govenor and how much cores are active, undervolting may increase your battery life too.
Play with the settings (PLEASE DO NOT RAMP UP THE CLOCKS or set the voltage to the lowest point you can, it may break your phone, stay reasonable, it's not my fault if your phone bricks) and look what's best for you.
Pro Tip: Take a look at the different govenors and look what they do. Google them!

I hope I could help you a little
Im using trickster mod and I know about all of this I studied up and have undervolted by 200 MV stable but I'm using the hotplug settings to 1:2 so not all 4 cores are active and I get almost two days on one charge!so I guess that does mean less cores use less power

I remember back when I had a Galaxy Nexus that it was possible to not only overclock it's CPU and GPU but also its memory. Now this got me thinking that since the Nexus 10 has a less than ideal amount of memory due to it's high screen resolution, maybe overclocking its memory might help performance and multitasking.
Now the question is.... is this possible to do?
If I can remember correctly some of the custom kernels have memory controls. KTmanta comes to mind. I think you may need the kernels control app to get at those settings. Also I'm using Tempest ROM an OMNI ROM variant and it includes numerous memory settings which may be what you are looking for.
You would need to enable developer mode then Settings->Performance, settings select "tabbed mode" then select the "memory" tab.
I've never messed with those settings myself but they are there for your amusement.

Maybe try this

But of course depends on what kernel you are running, haven't used it on my n10 but works amazing on most my other devices

KT has memory frequency exposed and I think that is the only one. That being said, no matter what settings I try on KT, Trinity 10 outbenchmarks it with mostly stock settings. That suggests to me you should probably look for a different way to improve your RAM performance, i.e. minfree values.
