I have a problem with MI5, it is starting to show signs of Burn-in, the only way to get these signals is to calibrate the display colors to 80%, custom ROMs offer this feature to calibrate but not MIUI, I really like MIUI, I would like to have some Functional Kernel that has the ability to calibrate the colors through the Kernel Auditor, or if there is any program that gives me the ability to calibrate
DragonXia kernel by WhyOrean has RGB value modification in kernel adiutor for the CM/LOS version.
I assume the MIUI version is the same:

its a LCD isn't it?
how did you managed to burn it in?
is it become yellowish?

2) Madmack's NoLED app:
http://forum.xda-developers.com/showthread.php?t=730692
I would like to know Which one is better for battery saving? I know it's very hard to tell, I'm just asking about your impression in real life usages.
I did a pool to study which one is more popular.
Anyway, both are great, thanks for creators.
Using BLN free to notification system, and just seem to be a regular battery drain.
The app NoLed I was very happy, but it reflects a larger battery consumption. Mainly influenced by the consumption of active display - black backlight.
App BLN is not as spectacular, but is fully functional and almost no consumption effect. LEDs can be lit throughout the night and the battery life with almost no impact. Here I recommend buying BLN Version Control Pro, which can be dealt with activity LEDs.
Hey everyone,
I seem to be having an issue with the battery temperature sensor. It will always say 30 Celsius even if I can feel the heat of the battery through the case. Is this a known issue with the tabs? Using sensor test, I can see that a temperature sensor works and is constantly updating, showing temps from 30C to 40C. I'm running stock rooted EC02 with KhasMek Voodoo Plus OC 1.4Ghz.
Thanks for your help.

There are 2 main reasons for a constant temperature:
1- A third-party battery is used which have its temperature sensor removed, you will usually see 0.1 variations, like 30.0 and 30.1 at all times. or more often 25.0 and 25.1 (not sure why though).
2- the ROM or kernel is broken with regards to providing temperature to battery apps. Battery apps get temperature from Android OS using well documented API, which have not changed since the very beginning of Android. See here for more information about the API: http://developer.android.com/reference/android/os/BatteryManager.html
Unfortunately it seems to affect a few ROMs now-a-days.
EDIT: Are you using a S3 with CM-based or OMNI (AOSP-based) ROMs?
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
Hello, I would like to ask which is the best kernel and configuration (governor,io scheduler, etc) for battery saving? Also I need the kernel to be Pie compatible and I would prefer if it supported DT2W. Thank you very much
I use Dark Phoenix Fade kernel by Harukey. I use default setting/config. and it has pretty good battery life. I can reach +/- 24 hours for normal use (LTE data on, casual browsing, see 1 hour film).
Dark Phoenix Fade has DT2W also and yes, it supports Pie.
