Havoc os's battery isn't that good cuz it's comes wid hardrock kernal beast 13 (maybe) so after tuning it's still doesn't give good battery backup and even lil bit lags
I set cpu governor to powersave and that was extremely lagging so i put that on conservative but still I'm facing same battery draining issue i don't know I'm gonna get at least 7 hours of battery backup LOL
Can somebody fix it? I think installing normal kernal can fix it
So please provide if anybody have

Hey all 2X lovers!
Ive been thinking more and more of some overklocking here and Im running this ROM so I can overlock. Im running SetCPU for running different profiles and lovering CPU speed to save battery. I know it can overlock too with doing the setcpu.txt files but how do you increase voltage in the textfile?? Or can I run Pimp my Cpu at the same time as SetCPU without problem?
What speed/voltage is safe and draws not too much more battery??
And yesh Ive searched for this but didnt really found any good information..
I think use Pimp my Cpu only is better, it's because most x2' kernel developers suggested to use it.
I prefer stable rather than saving battery. If you having serious problem of battery drain, please wipe the battery stats while your battery is full(for make sure it's full, keep charging 2hrs after 100%)
Ok Ill look more into Pimp my CPU then
What speeds and voltages are you running? PMC suggests certain voltages at some overclocks, I assume you should follow them?

I just wanted to know what doe's the kernal do to reduce battery using ? is it only reduce CPU usage and speed ? cause if that so i can use setCPU and dont have to change kernals or anything
and if not can you please tell me what's the best kernal for battery saving for MIUI rom on nexus one
I've received Nexus 6 from FlipKart, Its great but two major concerns:
1. Screen is very yellow (warm color) and on reducing brightness it becomes magenta. When compared to any other phone including Nexus 5, its extremely yellow. Tried couple of apps, none of them do a good job of fixing the yellows. Did anyone find a good app/setting to calibrate this screen right?
2. Battery life is pathetic: From 100% to 10% in half day. SOT is barely 3 - 3.5 hours (Greenified Facebook, Encryption off), no gaming, where as my friend gets 5hours. Sometimes phone hangs and switches off. When I switch on, it looses 15% battery. It has only been charged 2-3 times (only got it 2 days ago). Does it get better with time? or Am I having a faulty battery?
Update: forgot to mention my phone shuts down at 28% battery. And it didn't boot at all. I realized battery was zero. Is this calibration issue? Or bad battery
Flash elementalx, you'll be able to change color values and battery life is great
1. You can change your RGB using any kernel with support to it. Almost every single kernel have support to RGB LCD KCAL. Use a app such as Trickster to modify the RGB once you flashed a kernel of your choosing.
2. Battery life is subjective to how you use your device. Just because someone was able to achieve 5 hours+ SOT doesn't mean you will either because there are way too many factors that play into effect such as: cellular signal strength, wakelocks, apps installed, etc. If you want to maximize your battery life, look into underclocking the CPU/GPU frequency and flash a custom kernel (e.g. Franco) that removes mpdecision. Mpdecision is a huge battery drain and the frequencies that it selects is completely random and unnecessary in my opinion.

I agree that mpdecision really does drain battery a lot. I have mine OVERCLOCKED to 2.88 ghz with sensei kernel and intelliplug. And I am still getting way better battery life than stock. Just flash this kernel with intelliplug and there goes your battery issues. And you can also adjust your screen colors.

For more elaboration on mpdecision,
All Qualcomm based phones have Qualcomm prorprietary userspace binary called "mpdecision" aka m(ake)p(oor)decision. Instead of letting the kernel itself to decide what frequencies and how many cores to run, this "mpdecsion" binary polls the kernel run queue statistics and decides for the whole system the "optimal" frequency and the "optimal" number of cores to use. The concept is fine, except the decision making is done in userspace and it's 100% closed source so there's no way to tweak it and there's a latency (because all userspace binaries needs to "poll" the kernel for the latest information which is slightly delayed). - faux123

In other words, mpdecision makes your phone sit at 1.5GHz for doing the most simplest tasks, even composing a email it'll bring your frequency to be at 1.5GHz.
Download CPU Spy and use your phone, then look at CPU Spy and you'll see how much time is spent in that frequency. Then flash another kernel that does not use mpdecision then you'll see the difference, the phone sits at frequencies that makes sense for the load that is on the device.
The alternative solutions would be, Franco's Hotplugging Algorithm or intelliplug by Faux.
Battery life is very subjective.
I am still 100% stock, encrypted, auto brightness and get over 6 hours SOT every charge. Mainly WiFi, some LTE. No gaming.
I will root and switch to another kernel when I have time and see the difference. I would expect more battery.
However if you are only at 2.5 hours SOT on a full charge, I wouldn't expect it to double just by changing kernels.

Thats so impossible. I've switched to 2G only but i run on Wifi all time and yet 1 day standby and 3.5hrs SOT.

Impressive! I'm trying ElementalX kernel right now. Is it safe to switch-off MP-decision on that using trickster or shall I go with franco blind folded.

Well, not impossible as it has been that way on my phone since day 1.
But i agree that it is really odd how some people are getting 3 hours and others getting 6.
I had the opposite on my Note 4 though. Everyone got 6 and I got 4. So who knows?

You only want to disable MPDecision if theres a alternative. For Franco, mpdecision is 100% removed so you don't need to disable anything.
I don't know ElementalX so I can't say, ask in their thread. If you use Franco, everything is done for you and you don't need to do anything on your part.
My battery life with LK is pretty good as well! I was able to tether for 10 hours straight and still had 22% left after sleeping ~8 hours.
Hey all. I'm running Chroma 7/1 on Zen 21 right now, and I can't say I like the battery life I'm getting. What kernel have you found gives the best battery life? Or what settings? Other suggestions? Lemme know. Thanks!
It's hit and miss. We don't know what else you are running as far as apps and settings go, so it's basically trial and error until you find What's best for you.
right, it all depends how you use the phone.
me, im a heavy user, lots of browser action. but i dont do much gaming. i like performance, but i get great battery life as well(about 5-6.5 hours sot). i strictly use ondemand/deadline, no hotplugging, fsync off. also, i like despair, vindicator, and elementalx kernels, but thats just me
oh, signal quality plays a huge role in battery life as well. so does screen brightness, keep your screen brightness down. i keep mine from 15%-0$.
I use elementalx. It doesn't have better battery life than any other kernel - they are all the same. It's all about tweaks..
Setting the up threshold higher for example, will change the % of load the cpu must be under before it ramps up to the next frequency or even to turn additional cores online.
Thanks. I guess it's trial and error then.
I've been using aicp and stock elemental x with good results.

What improved the battery life of my N6:
Franco's kernel (default setting);
No wallpaper app;
Pixel battery saver;
Replaced apps with white background by alternative apps with a black background.
Installed/flashed apps modded by the Team Blackout
Disabled not used g-apps.
Disabled not used services
Share your benchmark rank here. And which rom,kennel, any mod/twick do u prefer use for the most perform & battery life?
Mine: benchmack 12562, i am using slimkat+F kennel + L speed. Its fast,smooth and good battery life for me
Sorry for my bad English
I have something about 1150 with quite good performance, but battery drain too fast. However, I could be problem that it was keept for a long time fully discharged
What mHz can you use without reboots?
I set at 1100 with i/o noob
How could you call me like that...?
On 1150, CM12.1, F-kernel and L-speed Ive got 1270 points. Before I used Fly-on mod, but L-speed seems to be better.
Ive try out Fly-on mod, L-speed & Skynet. For me, L-speed is the best. In Novathor, i set deepest sleep state is state 4, so battery isnt too much. And i always disabled KSM, it may cause battery drain. My benchmark points is between 12k - 12k5
Och, there is a new version of F-kernel - 1.6 and dev said that novathor doesn't work propertly so you have to do it manually. In /sys/... folder you can change deepsleep state.
