The battery level is re-calibrating automatically at boot. Just do a full discharge till the phone shutdown itself and re-charge to 100%.
Normally even this isn't needed since li-ion battery doesn't have memory effect. Also if you are still using the old battery, now it's older and have less capacity.
To check the real battery capacity: once it's 100%, unplug the cable, wait 10 minutes, reboot and check the level. If it drops to 80%, that's actually the real capacity and there is nothing wrong with the kernel. Also you can't re-calibrate to stay at 100% after an reboot. Only fix is a new battery.

Installation
Step 0
This step is only needed if your Android version is lower than 4.
If you have already Android 4.1.2 or even 4.4.x installed, then go to step 1.
Update to the latest Samsung stock ROM 4.1.2 with ODIN.
Make sure your battery level is at least 70 % before you proceed.
I'm a noob, please show me more details:
Download needed files for Windows (for other OS, please search the web):
For the GT-I8160 you need:
I8160XXMB4.zip (3-parted) and
ONE-I8160XXNF2-20140930142454.zip (Latest stock ROM)
For the GT-I8160P you need:
CODE_GT-I8160P_I8160PXXLK2_CL1211774_REV00_user_SEC_KEY_XLK2_4G.zip ( first 3-parted) and
CODE_GT-I8160P_I8160PXXME1_DBT_1106830_REV00_user_low_ship.zip (second 3-parted) and
DBT-I8160PXXMG2-20130820164646.zip (Latest stock ROM)
For the GT-I8160L you need:
GT-I8160L-3parted.zip (3-parted) and
PGU-I8160LUBMK2-20140603151522.zip (Latest stock ROM)
After you've downloaded the needed files and you've unpacked and installed the Samsung USB Driver, you can proceed wit the upgrade.
Note: All your data will be deleted, so it's recommended to backup some important files to your computer, including the content of your sdcard.
First of all, export all your contacts to your ext-sdcard. Later you will need this file in order to import your contacts into the new ROM because the new ROM CM11 has a small issue that it can't read SIM contacts.
Now copy the exported contacts to your PC and then format the sdcard as FAT32 if you can, if you don't know how to do that, it's also (for now) enough to simply delete all files and folders from the sdcard.
Unpack Odin3_v3.07.zip and open the program inside, it's: Odin3 v3.07.exe
Unpack the ROM, for example we unpack the ROM: I8160XXMB4.zip for the GT-I8160 which is a 3-parted stock ROM.
Well, now power off the phone and remove the sdcard.
Press and hold at the same time: volume down + home + power button.
The phone will boot directly to "Download Mode", now press "Volume +" to enter "Download Mode".
Connect the phone with your PC with the USB cable (important: during flashing don't turn off your pc or phone, also don't touch the phone or the USB cable)
Your phone should be recognized by ODIN .. you can see this in "ID:COM"
if not, then the USB drivers for Samsung mobiles are not properly installed !
Don't change the check boxes !!!
Now load the *.tar.md5 files as follows into ODIN:
PDA = HOME OR CODE (*.tar.md5)
Wait until the MD5 check is done and proceed by adding the next package in ODIN.
CSC = CSC (*.tar.md5)
PIT = *.pit File (the checkbox Re-Partition is now checked )
Finally press "Start", be patient ... this takes around 7 minutes.
The phone will reboot several times. When you see the pad for entering the SIM PIN ... then the (3-parted) ROM was flashed successfully and you can now remove the USB cable and reset ODIN and you should flash the next ROM with ODIN which is:
flash it exactly like the 3-parted one, with the difference that it's only one file to add in ODIN .... see the screenshot "For latest stock ROM" which is odin.png.
Step 1
Download required files and copy them to your micro sdcard without to unpack them:
A2N Kernel (choose normal version, or if you want to increase the space for apps, then choose "sdcard_only", but you need micro-sd-card and you should perform re-partition - very easy - step-by-step)
Step 2
Flash a2n_kernel_gt-i8160_ODIN.tar with ODIN in order to have CWM recovery or boot to stock recovery in order to flash temp_cwm and then a2n kernel which will result as well in permanent cwm recovery.
install cwm over stock recovery ?
then boot to stock recovery ...
Navigate with volume keys to "apply update from external storage" and confirm always with "Power-Key"
Choose "Temp_CWM_6.0.2.8.zip" and confirm.
"install zip from sdcard" and confirm.
"choose zip from sdcard" and confirm.
Choose "a2n_kernel_gt-i8160_4.4.4.zip" and confirm
Tap "back key" few times and select "reboot system now"
When then screen is black immediately boot directly to recovery again.
Now the cwm version should be 6.0.5.0.
Step 3
Increase the available space for apps from 1,2 GB, up to 3 GB !
More Informations about the repartition: Post #3
This step is optional, so if you don't plan to install a lot of apps you can skip this and go to step 4.
flash cwm_cm11_partitions_layout.zip
OR cwm_cm11_partitions_layout_sdcard_only.zip
press several times the soft back-key, then tap
"advanced"
"power off"
boot again to recovery
mounts and storage
format /system
format /storage/sdcard0 as "vfat" [it's like FAT 32]
Go back and "wipe data/factory reset"
"advanced"
"power off"
Boot to cwm
Go to step 5
Step 4
"mounts and storage"
"format /system"
format /storage/sdcard0 as "vfat" [it's like FAT 32]
Go back and "wipe data/factory reset"
"advanced"
"power off"
boot to recovery

Yes the Samsung Galaxy Ace 2 is still usable in 2022.
But the thing is you need to find a good gapps package.
Because using latest one from my download site or from opengapps.org cause Play Store to crash. But it works anyway. It crashes 1 or 2 then works stable.

Hello sir, is it possible for you to tell me how to use kernel control without Google services? Here I leave my email in case you want to check my payment. thank you very much for your work. [email protected]
Hello @jordirpz,
no way sorry. It's just the way how the license check system works. It's not possible to disable it for users where I'm sure they have a valid license.
But don't worry, new update for kernel and app with big improvements is on the way.
You will see that you will be able to use the phone with Google Play Services as well, having good performance and battery life.
It looks amazing.
Just found my Ace 2 and wanna try this to upgrade it to 4.4.4. but after flashing a2n_kernel_gt-i8160_ODIN.tar, I could not get into CWM. Tried with adb command also but no luck. It always boot directly to normal start. Do you have any idea @ace2nutzer
so you flashed a2n_kernel_gt-i8160_ODIN.tar with ODIN successfully?
To boot to CWM you need to power off the phone and then hold "power + home + volume up" till you see the first Samsung logo then release.
What Android version is actually installed?

My bad, I realized my home button need a hard force to work.
Finished installing cm11 and waiting for the first boot, but its over 5min already .... still black (I sawGalaxy Ace II screen once)
IF
you are familiar with ADB, try this:
boot to CWM and connect phone with PC.
Run ADB:
Code:
adb shell
cd /ramdisk
nano pllddr_oc_freq
change value from "1100000" to "1000000"
exit and save (Strg + X) then say Yes (Y) and press ENTER to save.
ELSE download latest a2n_kernel for 4.4.4
unpack, open file ramdisk/pllddr_oc_freq with any text editor if you use Linux OR if your use Windows, use any C++ text editor to edit the file.
Then just change value from "1100000" to "1000000"
save, exit and repack the kernel package without other modifications as zip package.
Note: only zip compression works. END IF
Finally wipe dalvik-cache in CWM and reboot to the system.
If CWM ask for ROOT, just say NO.
After the Samsung logo disappear, you should see after 4 sec the cyanogenmod boot animation.
Please let me know if this works for you.

OK, but make sure to perform all the required installations steps from first page or your phone will not work properly.
I've to assume that you didn't read it, because factory reset is mentioned in step 4. Also you need to format /system partition and internal/external sdcards.
For gapps there are two links, one from official website to get latest version and a link where you can download a known working package from my download site.

Changes After the Repartition
cwm_cm11_partition_layout_sdcard_only.zip
The total space from sdcard0 will moved to /data - so that's why a real sdcard is mandatory here.
/data is 3 GB for apps - max. possible!
No problems with apps installations
No wasted space !
cwm_cm11_partition_layout.zip
sdcard0 will be added with 1 GB size... and you're able to use also micro-sdcard (sdcard1)
/data is 2 GB for apps.
No wasted space !
For reference purposes, the original partition layout has following setup:
sdcard0 is 1,1 GB
/data is 1,2 GB for apps
Some wasted space and too low free space for installing apps.
How to Disable EOC(end-of-charge) BLN(backlight notification) for LPM(offline-charging) + Recovery
Open "FileManager" ---> Settings ---> "General settings" ---> access mode --> "root access mode"
go back and navigate to the root "/" open the file "user_lpm.rc" and check the content.
The same procedure is for "user_recovery.rc" if want to disable it as well in recovery mode.
Also there you can do other things like enable/disable sweep2wake or change the lcd brightness for LPM or recovery.

A: Everytime you install or update this kernel you will face an red (demo) app "A2N Kernel Control..." open this app, and it'll redirect you to Google Play to get the full version (blue app).
Q: Can i use and Tune your Kernel with other Kernel Manager Apps ?
A: Yes, but you need first to unlock kernel with the A2N app full version.
Q: I've Installed the Full Version of the App, Will it Change any Kernel Settings by Default if i do not Change them ?
A: No, default app settings = default kernel settings.
Q: I've the Full Version of the A2N Kernel Control App, Do i still need the Demo Version of the App ?
A: Yes, there are some special features in-app-menu like "Fake Enforce" and debugging features for easy bug reports.
Q: How to Charge from 10 % to 100 % In just 1 h ?
A: E.g. set "AC Current Max" and "Maximum Charging Temperature" to the Max.
Q: Can i use your Kernel Control App with other Custom Kernels ?
A: No, it's not universal kernel manager app.
Q: My A2N App shows: "Please check your internet connection" - But i've good internet connection. - How to fix it ?
A: Settings --> network settings --> use private DNS server like "dns.adguard.com" - confirmed to work by user @Arnz09 - see his post here.
Q: My A2N App is Crashing after an Update, how to fix it ?
A: Re-install it. If it doesn't help, wipe dalvik-cache in recovery.
Q: How to Report Bugs ?
- Please DO NOT report bugs if you are: --- using "unsafe" Freqs
--- not using the latest release !
--- not using Samsung stock ROM (based stock ROMs are custom ROMs !)
A: Open the red A2N Kernel Control demo app and check in-app-menu (3 dots) then "Debug" and then on "logcat and dmesg" if you faced an app crash or if some features didn't work.
If the phone rebooted randomly, then tap on "last_kmsg". You will find the logs in your internal storage. After that you can attach them here in your bug report, by clicking "Attach files".
