[Q] Need advice in switching from CM7 to MIUI

I'm mostly a lurker and try not to post much since most any question I have has already been answered (I've spent hundreds of hours on here but only posted a couple of screenshots), but I am looking for a little advice. I have been running CM7 with Tiomat kernel on my Evo for about 2-3 weeks and am pretty happy for the most part, but now I'm getting itchy to try out MIUI for the first time.
1. How does this forum infect people with the insatiable urge to constantly mod? ;-)
2. Any tips on a smooth(ish) transition? This is a pretty subjective question but I figure I will learn more from your answers than in dozens more hours poking around.

You'll be hard pressed to go back to CM.
Get the newest MIUI from MIUI.US
Use Aman Ra, Wipe Everything except SD Card and Battery Stats, if you're not fully charged. Flash MIUI then DT A2SD, if you're partitioned, boot up.
Let it settle, Reboot to Recovery, Flash Kernel (Tiamat 4.1.0 and 3.3.7 Are recommended)
Boot up And have at it.

Hey bonillamktg,
Ive used Miui for a few months as a daily driver and to be honest i loved it, its a simple interface that is easy to use but filled with features. You can overclock it stock with set cpu , out of all the roms i have tried so far i would say it was the smoothest, that flowed the best, the only issue i had was some problems with video recording. but besides that it gave me the best battery life i have ever had over 24 hours on a single charge with the stock evo battery. personally i would recommend it, and I liked it better then CM7 "only my option of course". But I say give it a shot, just nandroid up before hand so you can flash back if you dont like it!
Enjoy, hope I somewhat helped lol

Thanks, HipKat! I just read through your entire Ultimate Guide to Everything Evo 4G and learned a ton. That is probably the single most valuable post I've seen on any forum.
I've already been using Tiamat 4.1.0 and it has been good to me, so I'm glad to hear that it works well with MIUI. I fell asleep soon after posting this but I'm up now so I'll let y'all know the results.

Stevo, your description is exactly what I keep seeing over and over that makes me want to give it a shot. I feel like my setup now is a bit clumsy, it gets the job done but I have to go to 20 different places to tweak everything. Thanks! I'll let you know what the end result looks like!

Thank you!
The best part about MUIU is all the hidden little things you can do. Read the OP in the MIUI forum. Plus the built in themeing capabilities are limitless

With or without SBC?

I only use SBC

Yeah and thats what I was reading all about before I gave it a shot to. I say go for it and give it a flash, it really is a nice smooth rom. One thing I forgot to add before when ever I use a sense rom I am normally getting around 150mb free ram, but on MIUI I was getting easily 250mb! & yeah I feel ya, its always a pain to tweak everything to perfection. Well hopefully Miui works out for ya! Your welcome, an thanks for keeping me updated on your journey haha. Good luck

HipKat, wondering if you would know why I'm having an issue. I was actually hoping that this type of feature might be built into MIUI, but I've been using Wallpaper Wizardrii for a little while now because it crops properly for non-scrolling wallpaper and doesn't pixelate...at least not until now. With CM7 & ADW.EX, it worked perfectly, but now, it is pixelating horribly. It's not the images, they are the same ones I used before that worked well.

In ADW ex, do you have the wallpaper hack option turned off? I think that option has something to do with wallpaper quality or color depth or something. You can also try Superwall lite or MultiPicture LWP. They're both live wallpapers, but I've seen no battery drain with either and I've used both. Superwall might be better since you're just using one image.
I get amazing wallpaper quality with MIUI, especially on the default launcher. Clear defaults for ADW or use a home switcher app to see what the wallpaper looks like on the default launcher with the same app. If it looks fine on the stock launcher, it could have something to do with your install of or settings in ADW.

I tried turning off the wallpaper hack and then went back to an image I used to get clearly and it was split in two, basically the left half of the image was moved over to the right.
You are right in how impressive the image quality is on MIUI's stock programming, even using ADW. If I really wanted to, I'd take an image editor, even something basic like MS Paint, and edit an image so it'd be centered where I want it. I change my wallpaper too often for that, though.
I found the Flikie Wallpapers app which has some great wallpapers, but I'll remember Superwall Lite for the future.
Thanks so much for the advice!

Here is where I am at now. I like the combination of Minimalistic Text, Missed It! and Quick Agenda that I put together at the top. I wish I could've integrated the SwitchPro widget into it, but it isn't scaling right for me (It leaves a big gap that I don't like). It's also not letting me edit the images for the switches, which I want to do before integrating it up there.

well i for one have tried the tiomat kernel on the MIUI rom and so far I noticed that my battery drained a little faster than usual. The one thing i did like about it was that i was able to use the hdmi mirroring. But I went back to cyn kernel with miui in the end (^_^)

miui is awesome. i love how many pink themesbthere are...yes im a girl...and how i can customize the theme the way i want it. i promise that you will be addicted. its a lot better than any other rom, and im a flash maniac. i do have a question maybe someone can help me, I'm on the latest miui 1.12.9 when I do group text messaging it force closes? What gives? Any ideas?

Well, unless you use the extended settings, wall paper on MIUI does scroll, so maybe the images you're using are being resized improperly. FYI, and you probably know this, but the wall paper size on scrolling desktops for the EVO are 960px x 800px @72 dpi. 480 x 800 for lock screens.
BTW, you should lose the background on your Minimalistic text. or at least turn the opacity way down.

Just saw your post now, and hopefully hipkat can help you more with this, but i think your issue is to do with the rom itself. That is one downside of Miui there is no 720 picture taking and I really want to say the rom it's self has less resolution to it, when using it i did have a lot of low quality things images, and after flashing back to a sense rom I noticed much better quality images within pictures my backrounds and even just certain apps.
Hope that helps a little, is it just wallpaper your having issues with or is it other images?

MIUI is a 180 degree spin from CM completely different but its real nice you will enjoy it very stable and complete. The 1.11.18 version worked great for me then i tried 1.11.25 and had too many issues. By the way can some1 hlp me get a copy of .18 or .12 just to have? I cant seem to find it anywere and i didit save a copy. Thanks.

One reason why I don't use MIUI is because it doesn't have 4G support. So if you use 4G routinely, you may miss it.

True that. No 4G. For me, I don't have it here, anyhow, and have access to WiFi all the time, home and work

[Q] Android OS and wlan battery usage on FH13

Running unrooted stock FH13 I'm getting a high percentage of my battery being used up by Android OS when the phone is idling. From what I've gathered this seems to be a pretty common problem with the two official ICS builds, but I'm wondering if anyone has any solutions that doesn't involve reverting to GB or rooting my device. Better Battery Stats typically tells me that the culprit is a wlan kernal wake lock, and sometimes is deleted wake lock (which if I understand correctly could be the same culprit as the wlan_wake lock). So it would seem that Wi-Fi is what's killing me, but I've not had any better battery life when I run 3g all day either. I did a factory reset after upgrading to FF18, but I didn't do it again after upgrading to FH13. Any suggestions?
Also, does anyone know if FI03 has the same issue?

This is xda, why are you here if you don't want to root your device?
Honestly if you root it and get rid of the stock apps and bloat that runs in the background you will get better battery life. The first thing I do on official ics is delete the Sprint and Samsung apps like Sprint zone, media hub, social hub, and extra widgets like accuweather and dual clock.
There are guides everywhere for battery life improvement. Also turn off wifi when your not using it.

I appreciate the advice. I knew about that option already though. The reason I don't want to root is because aside from this one issue I'm fine with the stock experience, and I honestly just don't have the time to try different builds and tweak things enough to get the most out of a rooted experience. As far as why I'm on xda, there are plenty of unrooted leaks on this forum too so I can't be the only one who doesn't want to root for whatever reason. For general battery improvement, I've looked and I haven't found anything useful aside from either disabling some apps from starting up or accessing the internet at certain times, which would require rooting, or turning off data/wi-fi (which in my opinion defeats many of the purposes of my phone).
I am well aware that turning certain things off or removing certain apps, even those that would require rooting, would help my battery, but my point is that I didn't do any of those things on GB and my battery life was still perfectly fine. My current understanding of the situation is that this is just what the official FH13 ICS rom on the E4GT does and there's nothing I can do about it. I'm hoping I'm wrong and that someone might have some advice, but if that's really the case feel free to confirm my suspicion as well.

Only thing that comes to mind is - after you reset, did you go right back and install all your apps before testing for battery drain?
Did you try turning off auto sync?

Yes, I did just reinstall all of them immediately. I know that it would have been better to put them back on slowly in order to pinpoint an app that may be causing a problem, but that would have taken a lot of time and I didn't think it'd be worth it. Also, right now better battery stats doesn't show any of my apps holding a wake lock for long and I thought it would show up there if it was one of my installed apps causing the problem. Is that not how it works? Because I'm considering factory resetting again when I get the chance, so if it still could be one of my installed apps I might give the gradual app installation a try if I do it.
No I did not turn off auto-sync because being notified automatically about e-mails and such is one of the main reasons I use this phone. I know that it uses more battery when it's on, but I consider it a necessity. However, now that you mention it, I never really did try turning it off just to see how much of a difference it makes. That could be useful diagnostically so I'll probably give that a shot.
Also, on the auto sync note, is there a way for me to change the time interval that the google services wait to check for new notifications? Because I can't find it anywhere and I could have sworn that was an option in GB.

Disclaimer: None of the following is meant to be rude -
You're asking for a shotgun approach to a specific issue.
You do realize that the majority of people that your asking love to take things apart to find out what's wrong, right? Its kinds like taking the screwdriver away and asking someone to fix it.
That being said:
Autosync: App dependent. Check each app. If you have outlook, unfortunately its also on the server side for push notifications. If you have outlook, talk to the admin and ask if they left push at the standard default. You can find those settings through technet. I posted on this issue so you should be able to find it in search.
Each app install: Without a logcat at a minimum, or a verbose battery monitor app, that's a needle in a haystack. Either
A: go the "one at a time" method
B: Research each app for same issue
C: You can find similar posts on this issue since its such a popular one and try the various suggestions.
Either way, you're going to spend the same amount of time, or more, hunting this down.
Ooor, since you don't want to root:
You can flash ek02 and let the OTA process take you to el29 and try the no root method of ignoring future updates or hit the ignore button several times a day.

You can be stock rooted on the current over the air build if you are happy with touchwiz ics. When I use touchwiz based roms stock rooted is the way I go. You don't need to worry about tweaks or custom kernels if you want to keep it simple. We all started stock rooted, its a little scary at first but its really the way to go if you want the most from your phone. Its one of those things that you kick yourself for not doing sooner when its finally done.
I have been able to surpass my battery life on EL29 GB with various ics roms for months with similar customization done. Bone stock though I think you are right GB is a little better. A new official ICS update should be released soon FI27 though and they only get better. Give it a try stock and really consider rooting. We will help if you need it.
FYI this is a normal days battery for me. I'm currently running an AOSP rom with stock battery

Codename-Android-(JoyRide)-3.6.5.10012012-ALPHA

Samsung Galaxy SII Epic 4g Touch
I have recently installed this new ROM and I love it! One down of it is the battery life. But I've disabled google now services and my battery improved at almost 40% lol It's nice to have it but It's also annoying to charge your phone every four hours. Im pretty sure there is a bug continuously running that drains the battery that fast. or maybe this syncing options are not very efficient.
Now going back to the point, the bad problem is that my phone is not recognizing my memory card. Other programs recognize it like file manager and others but every time I go to gallery my phone doesnt recognize the pictures from it. Also the music player doesnt see the music I have on it either. Frustrating :/
I have done so far this:
1. Unmounted and re mounted the memory card using the ROM
2 Unmounted and re mounted the memory card using the ClockworkMod
3. Formatted the memory card many ways and different formats
4. Used a different (blank) memory card with one file
I also read another thread from previous codename ROMs about putting a null file on certain folders? I cant recall it right now, but theres is one thread about it. That did not work as well.
Does anybody have this issue about the memory card? if anyone have any other thoughts or any solution please help and lets discuss about it.

Yes i had that issue as well, I just moved my pics and music to my internal card. its a quick fix. But I had that issue on CM9 but not on CM10 tho. just those two. So, hoped this helps ya. I really didn't look into it that deep. as soon as i moved the stuff over to my internal, I was good. you might wanna search the new CNA thread. see if there is a fix in there.

Did you do a clean install? My battery life on the current version of Codename is very good and only a bit less than ICS. There is some JB kernel development in place at the moment to clean up some of these remaining glitches. That's why this and other JB ROMs are still in alpha.
What governor are you using? Try pegasusq governor, it works for me. I'm also slightly undervolted.

This is from a fairly normal days use, heavy on Pandora. Stock battery

lol read a battery thread.. your setup is causing your battery drain.. or you have a bad battery. theres also plenty threads (mostly aosp rom threads) that have that issue.. not sure if directory bind will help?

Havent even thought about that. I'll give it a try tonight and I'll let you know. And I know this is an "under-development" ROM. I fixed battery problems but I think Im more worried about the gps than anything else :/ I'll look around for some other solutions

If everything worked like it is suppose to while flashing, GPS lock is not an issue with this ROM according to the development team. I have been using it for a few weeks and the only time I had GPS issues is when I tried out a few other ROMS for a couple of days and then nandroid back. GPS, batt issues, and messaging issues showed up, so it probably didnt get wiped very well before I restored teh nandroid.
Try a fresh install from GB kernal and see if that helps with any issues. That is what I did a few days ago and everything is working well again.

You have to get a gps lock in a touchwiz rom before flashing this for best results. I just used the fi27 one click for that. Do the one click update prl and profile, got a gps lock then flashed codename following the instructions on what to wipe.

Thanks, did that and it didnt work. Everything seems to be pretty good with this ROM except the ROM. Did a clean re install and the same. I guess I did something wrong, but for what I've been reading, a good percentage of people is having either the gps issue or the memory card reading issue.

There is a fix for the GPS in development called JB Tweaks. My GPS would lock in about a min before, but now it takes 10-15 seconds. I would recommend using Alpha 1 build for now. Some are reporting fc's on 3 and battery drains on 2.1.

CNA is actually a pretty sturdy ROM. Your battery life issues can't entirely be fixed, but they can be improved greatly by a few simple things:
- Use CNA's "Performance" tab in the settings. It should be right there towards the top.
- Underclock your CPU to 800 - 1000MHz. There isn't a huge difference between the two, but whichever you prefer. I don't do a lot of gaming type processes on my phone so I am perfectly content with 800MHz.
- Change the I/O Governor to "pegasusq" with a matching I/O Scheduler of "noop." I've personally had / seen a lot of people have success with that combo.
- Turn off completely your Auto-Sync. I have my e-mail settings set to only refresh when I tell it too. Same goes for Weather applications, or any app that will run in the background invisibly, especially Facebook! Watch out for that one. They can prevent your phone from deep sleep.
- Change your brightness to a setting that is comfortable for you during the day and night, so that way your phone isn't constantly trying to do that for you.
- INVERTED GAPPS. The dominant black really helps keep the screen from using a lot of power and you will probably notice a difference when the battery has been calibrated correctly.
Hope some of those tips help you out! It's taken me some time to discover what I am most comfortable using, but I have figured it all out.
As for the SD Card issue. Might I recommend trying a different Root Explorer? Perhaps ES File Explorer or even "Root Explorer" from the Play Store? I know there has been a few issues like that for me, and honestly, I am still trying to figure them out myself. It somehow manages to correct itself, because I will wake up the next day with it working just fine. I personally use ES File explorer. I love the layout and it's free. Can't beat free.

Thanks for all the tips man! they are incredible and I've done some of them too. I stated at the beginning that the battery was really bad but I've managed to fix all those problems. A good calibration helps a lot too. Later I said I wasnt having problems with the battery and discovered my GPS wasnt working. I think Im gonna try different things ( I havent tried anything because school is killing me and I have time for nothing) so little by little Im getting there.
but thanks anyway, those recommendations are just perfect for anybody that wants to have a better battery life

A good calibration helps a lot too. Later I said I wasnt having problems with the battery and discovered my GPS wasnt working. I think Im gonna try different things ( I havent tried anything because school is killing me and I have time for nothing) so little by little Im getting there.
but thanks anyway, those recommendations are just perfect for anybody that wants to have a better battery life

GPS is an easy fix, get on a tw rom, turn on GPS and get a lock, leave GPS on and locked, then boot to a safe recovery and flash the rom u want to use. GPS will now work normally, if your lock is slow on the new rom download GPS status & toolbox and clear A-GPS data and redownload the data and it will lock fast, I can get lock within 2m indoors in less than 30sec on my et4g

"Gym Rom", aka Retired Gnex, what do with?

Ok, I've retired my Gnex after a lot of love. It's currently running PA 3.99. It just couldn't complete with the days and days of battery life of some of the newer models. I'm thinking of putting a barebones build on it, but that seems to be counterintuitive to everything android. Every rom in existence has every feature known to man enabled, and they are all bloated.
Does anyone know of any rom maker that would be interested in taking the PA source, disabling 99.9% of the bloat, and making me a "Wifi streaming / mp3 playing / 4 or 5 days of battery life monster. I'll affectionatly call it "Gym Rom"
I assume that something like 4.2.2 with AK would be a good start, as AK seemed to be the best battery life.
Being that this is going to be a wifi only device, what is the best way to disable LTE/3g? I know it can be done in settings, but is there a rom way to do this?
Other things I'd really love to see rolled into "Gym Rom" -- Nova launcher, MapMyRun, Myfitnesspal, Zombies Run, and Apollo.
last but not least, gapps, but really only the absolute basics -- Play store, so the apps can be installed if needed.
Thoughts?

Uhh... Take a pure AOSP ROM, install AK and your desired apps, and go Airplane Mode? What's the point of having the devs do everything for ya when DIY is a few clicks away?
And to have Play Store you need to sign into Google, which then requires several other apps in the gapps package.

I can think of like 6 stock roms out there, that's just off the top of my head. Anyway, don't expect to get 4 days out off a charge on this device. Rom or kernel won't get ya there. Screen is the biggest battery killer, and the hardware has probably half the efficiency of the latest and greatest. S800 pro is double the cores and double the frequency, and uses less battery than this.
You could probably get a days worth of music listening, if the play list is long enough so you don't have to turn the screen on to change tunes

If right now it's a media center only, you'll get more battery life without the radio usage. Please try to test it without the simcard and post your results with an AOSP rom.

Gnex is hardly a media center with its 16gb storage an no sd card slot unless you plan on streaming everything on it.
You want best for WiFi, mp3 playing an good battery life, you should try stock as it has the best battery life compared to any custom rom out there, good luck getting 5 days without charging use out of a gnex even while only just using WiFi an music on it, not even possible with the standard gnex battery.

dude, what you really need is a table like the new nexus 7. Buy the wifi version. Mine lasts about 7,5-8 hours of SOT and about 4-5 days till battery goes to 0%. And that with watching videos, movies, playing music. What you want can be done but no point since gnex is actually a phone and not a media center or a wifi tablet. If you root your nexus 7 tablet and delete some system apps you may get more battery than what I said earlier

I'm just going to wipe and install http://forum.xda-developers.com/showthread.php?t=2471380 as it seems to fit my needs the most, then install some root file explorer, and delete the stuff I dont need. I'll try to remember to post back in a few weeks with a battery life update.

Plus, if you want a media center you'll need an extended battery; I'd go for the 2000 one
BTW: What I mentioned on earlier posts was because I'm using my Atrix as a media center and the battery usage reduction after I've not been using the modem on the phone, seem to had a good effect on battery life (I'll try checking on the Gnex, but I'm waiting my 2000MaH batt to come.

I have a 32gb with 2100mAh battery on mine and modded mine to do Qi Charging.
With the radios disabled, I would think you would get quite a few extra hours on it. If you are wanting to convert it into an "iPod Touch" then do just that. PA is fun but I found the best battery using AOKP. I might even attempt to flash MIUI and use it, MIUI has the best Music app IMO. Even the 16gb version is PLENTY of space for tons of MP3s. I have an 8gb iPod Nano and I barely have 4gb on it. It ain't like you can't update the music occasionally. And use Pandora (which is what I mostly do these days).
I would download some sort of Music Player lockscreen (solid black theme) since our AMOLED screens only use power of ON pixels. I would keep the entire theme as black as possible to reduce the screen power consumption. Basically everything would be black and white except the Cover Art.
Also what ever happened to the CM mod that would turn the whole screen into all one shade of 1 color (like green night vision)?
Since you are disabling most of the connections, I would also get a battery saver app that will stop background processes like Google Play and stuff from attempting to fetch updates when on WiFi. I would turn off any type of syncing I could. I would make everything manual, that way you aren't working out, listening to music, and hearing notification tones.
Then I would grab some card games like Uno, Chess, Checkers, Solitare, Word Search, etc for Offline quick plays. Just simple stuff.
Maybe a news agitator that is easy on the pictures or no pictures, just text feeds/articles with a black/white theme so you can manually sync at home before you leave or when you want, and have some good reading on the go.
There are lots of ways to really keep the battery low and use the phone as a media device.
You could also use it in your car with one of those BT Car Computer readers and Torque app. Along with GPS.
Use it as a "Gameboy" by downloading a bunch of emulators on it and either using the onscreen controls or a BT Controller like a Moga.

I literally just did this last week to my retired GNEX. I just put on the newest CyanogenMOD ROM and have in airplane mode with WIFI on, if I tether. Since I don't get WIFI in my gym, and mainly use WIFI when I'm browsing through social media and/or websites while I'm sitting in the sauna, I throw my SG4 into tethering mode and leave in my bag outside of sauna. I used to bring my phone into sauna but i fear the heat is too much.
As far as music, I just load MP3's onto the device like I would with an actual MP3 player. I found this being the easiest way to get music all the time and it saves battery. I've used it at the gym for about a week "5 days" around 2 hours each time, so you figure 10 hours of play back so far. Though I've left my phone on for a total of 1 full day. Sometimes I forget to turn off when I'm down. I haven't charged it yet, I only plugged in to computer right now to take screen shot and transfer.

I'm looking forward to doing this as well as soon as I get my next phone. I think the Galaxy Nexus can still be a useful phone, even if it is a bit old. Bluetooth can't be used while in airplane mode though, right? Can't one just turn off network radios instead so that bluetooth still works? Would love to be able to use the phone as a media player in the car, connected via bluetooth.

Wrong, I just verified myself. So yes you can use Airplane Mode and have fun with WiFi/Bluetooth. Satisfied, no?

Thanks so much man! I guess I've never had reason to try since I've only put it on airplane mode when I'm on a plane or out of the country.

Build a 4.0.4 AOSP rom yourself and use airplane mode? Maybe a custom kernel and some tweaks (governor tweaking etc.), but than your at the limit of battery efficient. Just don't use a google account or turn all the sync off.

[Q] Need some help on kitkat 4.4.2 please!!

Hi everybody, I'm facing the below issue, that's resulting on phone overheating when using, battery temp is ok, It's something related to cpu, so I checked my battery usage and it's showing Android System usage high, sometimes it reachs up to 40% even when you let it in deep sleep:

}
so if I take a look inside of what apps are included it shows the below:
everything is stock, and this behaviour is observed only in kitkat roms, on my phone, don't know about yours but mine is like that untill I find the solution. I also think that this thread could be usefull to anyone who's facing the same thing. So anyone good hearted can help me please if it's not too much to ask for? I helped a quite people here, so I hope someone help me back here please. Thanks!
Summarizing, what app could be making the andoid system usage high? In android 4.3 doesn't happen to me, that's why I'm moving between 4.3 and the lovely 4.4.2. Thanks!:crying: :crying: :crying: :fingers-crossed:
To someone: I make this thread after lot of searching here on xda. So don't bring here saying that this shouldn't be here, because (now I'm on dr ketang rom v8.1) but it happened to me with every kitkat rom I have tested (dn3, phoenix, emotion rom, dr ketang-in this last one I can found something good, disabling media scanner can help you to calm down quite/a bunch overheating,-) so now is the time to calm down my android system jajajajjajaj thanks!

Had the same issue on KitKat ROMs but never overheating issue. Also my phone doesn't show more than 20% usage by Android System except when I install a new ROM. It usually drops after 2-3 charging cycles. If it doesn't then I can only recommend a fresh flash after wiping with stock recovery.

You are a Senior Member @Austtin, I can't suggest to you.
I can only share with you that this has happened to me with all the 4.4.2 ROMs I've installed. But as said in the above post, things do settle down after 2-3 days (i.e. 2-3 recharge cycles). After endless P&C's I've been pretty happy with Phoenix ROM V18.8 And Nadia Kernel (currently V6.1) with @mat9v max_UV scripts. Undervolting may help you with heating up issue but for original android system usage issue, I think some tweaking with LMK might help.

Really really really thanks for your replies. So this is not only happening to me, I'm glad and mad about this issue jaja. But hey I found something interesting!! Media scanner is 1 of the 2 big battery drainers here. After installing dr ketan rom using his utilities you can disable it. It would be superb if he can create his tool universally. I'm gonna keep my research tonight untill I find something usefull for all. I keep you informated guys. Love you and thanks!!
I'm complaining without giving time to rom. I'm a kind of flashaholic jaja, so I'm complaining about this with only 1 day or less of usage. So gonna see if settling the rom down by a few days this keeps going or it just stops. Thanks guys!! Btw now I'm dn3 v5.2 + using dr ketan multitool. But i love phoenix rom too. May be I move to it.
Edit: i was forgetting to say that I try dr ketan app in other rom but no luck. It mess up your rom. So that's why I think it should superb if he makes it universally..

Hey guys I found a really interesting and "a must" app that's working on n7100. enable/disable media scan app. Install as a normal app, then enter to it, and scroll up to disable, then touch it, set root perm and you'll have disable media scanner. Benefits? Stop quite the battery draining. Contra: if you move new media files ( pics, audio, video) to your ext sd card from pc it won't be recognised (if I don't missunderstood) for that when you plug it into your pc through usb, and you're planing to incorporate some media files, you need to open the app and enable it again (scroll down and touch). No big deal. And de benefit is quite good. Now your phone will be cooler than ever using kitkat roms!!
How do I know if it's enabled or disabled? First a pop up mesaage show and then you feel the "winter", after couple of minutes , when you're handling your phone. Lol jajjajaj. Dr ketan made the app. And it's universal and light weighted.
Now is the time to keep researching for anything else to save all the battery I can. And then share it here!!

Thanks for sharing that @Austtin . Gonna give it a try today. I've already achieved 10 hours (idle) on 1% battery with my current settings. Screen on stats are pretty much good too. Let's see what this app achieves for me
