I don't get this line "are not running stock crDroid-kernel". Did xiomi release redmi 4a kernel source? Anyways is it possible to know if this rom has the nougat battery mode shown. The one I'm using right now has only the default mode.Would switch to this If I can set the mode myself for example to ultimate battery mode.

Thanks

Are you running the latest official build. Is it possible to check if there are 5 different power save mode?

---------- Post added at 10:47 AM ---------- Previous post was at 10:45 AM ----------

I had tried an older unofficial build of crDroid earlier. It had the the battery mode as far as I remember. The battery mode consisted of 5 modes starting from powersave mode which at default gets enabled when the battery saver is turned on then efficiency enabling the battery optimisations, balanced for normal users, quick mode and lastly the performance mode but I still doubt that it works or not because for all these, the system needs kernel optimisation to be performed and still now the kernel sources has not been yet released.

If your device is rooted, I can suggest you to try Kernel Adiutor to check if your device goes into deep sleep mode when the device is not used. If your device doesn't goes into deep sleep mode then try some doze apps like Greenify, ForceDoze etc.

Its not that I got bad battery Life , just that I loved that mode in older nougat version. It gave me quite alot of batter life when I neded it.Right now I'm running a fully custom rom with amplify and greenify so don't want to switch to another rom If it doesn't have the 5 battery mode.

I would suggest you to use DisableService and disable those pesky services for a better battery life. Using Amplify without knowing proper settings for wakelocks causes delayed notifications and I'm sure that it has battery mode in this ROM but I'm on MIUI 9 now. I have flashed more than 20 different ROMs and I don't want to try any other ROM :crying: :p :silly:

After using DisableService and disabling unrequired services will help to save more battery then using battery saver and different power modes. In idle state, after using the app you'll notice almost no battery drain when phone is not used.

Men I'm using every posible way to save battery, even using microG insteed of google service and I still only get a mere 3h-4h SOT with 15-20h standby time.Maybe thats good since I never tested it to only stay on SOT. I've seen people achive 7h SOT on miui with this phone so I was hoping for at least 5h SOT

I have also achieved almost 8 hr SOT on MIUI 9. That's I'm on MIUI 9. I have even achieved almost 7 hr SOT on Lineage OS 14. I have already posted the screenshots for that. I had flashed picoGapps for every ROM I have tested.

did you keep your brightness to medium or low? I'm going to try to do a video test with aeroplane mode to see how much the display would go on nougat.And I think il probably change rom since this one gives my 10+% usage in standby mode at night.

I would suggest you this ROM indeed, because it was the most stable ROM I have ever tried, now in addition the hotspot bug is also fixed and now officially supported. Bunch of thanks to the developer. For good battery life, go for this or else if you really care about battery life like me, then go for MIUI 9 and debloat it. In addition, I had passed SafetyNet in MIUI 9 even after modifying system partition whereas in most of the ROM it wasn't possible due to build.prop mods by the custom ROMs.

To debloat, you can refer my thread: https://forum.xda-developers.com/android/help/miui-8-debloater-script-t3678972

And I had tried Lineage OS 14, I also would recommend it but it has the hotspot bug and also the device wasn't been able to use on mass storage mode and access files on PC. I don't know if this build of crDroid has the same problem, otherwise it was really flawless to use just like running on a butter :cool:

As I have suggested earlier in this thread, the simple solution is:

Case 1: If you are on MIUI 8 with custom recovery
a) Wipe system, data, cache and dalvik cache without wiping internal storage to keep your data safe.
b) Then flash the nougat firmware zip given in the main thread of this ROM.
c) Now flash the ROM given in the thread.

Case 2: If you are on MIUI 9 with custom recovery
a) Wipe system, data, cache and dalvik cache without wiping internal storage to keep your data safe. No need to flash the zip.
b) Now flash the ROM and reboot.

Case 3: If you were on MIUI 8 and directly flashed the ROM and facing backlight and VoLTE issue
a) If you have MIUI 8 fastboot rom then flash saving user data via MiFlash and follow the steps of Case 1 thereafter.
b) If you have MIUI 9 fastboot rom then flash saving user data and then follow the steps of Case 2.

Some users actually flashed MIUI 9 recovery zip via updater app in MIUI 8, which also creates this issue. Clean flashing is always recommended. In such cases, clean all along with wiping internal storage and then according to Case 3, follow the steps.

I'm flashing the rom right now since I'm on miui 9(backed up my custom rom and flashed miui from fastboot that fked up all my storage so I backup for nothing T_T )

All the best, and please verify on my behalf if the MTP is working after you connect the device. Calm down and sorry for the trouble. If you get success, please let us know so then this ROM would be the best ROM for the device till now! :good: :)

MTP working , 4g working . Quite a clean rom no gapps library (I found some custom roms that include them ).
The only problem I'm having is that the battery goes 1% for 1-2min of screen usage. Maybe wrong calibration because thats way to strange.
Also baseband shows as unknow dunno why.

You have to manually flash Gapps package in recovery. Go for pico version and for battery callibration either the battery is faulty then go for replacement or else in this ROM, use your battery till 0% or automatically turns off on its own and then let it remain for some time. In switched off condition charge up your device till 100% and then use the device. Don't use the device while charging.

Hope the battery issue also gets solved. :fingers-crossed: :angel:

You got it wrong, its a good thing that it comes without any sign of gapps I don't plan to use them.I use a google less system. And as you say it may be a bad battery. Its some months old anyways. Going to probably get a powerbank.

    About kernel source...

    Hi guys, very good news, Xiaomi finally had release the kernel source code for Redmi 4A, I hope we will get a full development now. Thank you..
    Also for Redmi 5, 5A.
    3
    Welcome! I know that's tricky but to get something good, you need to work a bit to achieve it! :silly:
    Did the hotspot tethering and USB tethering bugs are fixed in the latest build?

    yes fixed
    3
    And a new one : 7.1.2-20180120-rolex-v3.8.5
    Not tested, and changelog ? perhaps new camera apps...:confused:
    As per the reply below, no, no camera changes. That's a good thing.

    But as per general crDroid changelog:

    Changelog: January security patch and any LOS changes between last release and this release. Nothing on the crDroid side has been changed and that will continue to be the case.

    So security patch and LineageOS sync since well, it based off LineageOS.


    Oh, and for 4A-specific updates, it's just a double tap to wake toggle fix where you can't really turn it off
    new version 0180120 is out, changelog? camera fixed?

    edit *
    footej camera and lenovo camera app still there .

    Just uninstall them with adb/terminal emulator:
    Code:
    pm uninstall -k --user 0 [pgkname]
    and replace [pkgname] with com.lenovo.scg for Lenovo Camera and com.footej.camera for Footej. Footej is available on Play Store, anyway.

    And get like, CyanogenMod's Snap Camera off XDA, or Open Camera
    2
    Great ROM. Really smooth.

    Everything works fine but backlight does not turn off in lock screen.

    PS: Facing same issue with your HalogenOS build too.
