Yes, that was the mistake I made. So I can install the vkinger kernal, without having cyanogenmod installed? Cos when I do it with it installed I get boot loop
Vkinger is a STOCK SAMSUNG ROM kernel !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ... please read the topic before asking of course u will bootloop
I give up trying to install the kernal. I have no idea what I did wrong but after installing it with CM11 installed I get bootloop, after installing it without CM11 I get bootloop.
I wrote a mail to zerolemon seller on amazon and i got this back from him
1- charge phone while off for 12 hours straight.
You then will turn the phone on and use it till the battery life
goes to 2%
*
2-after the item has been depleted to 2% charge it for 12 hours
straight.
PLEASE NOTE: Your phone may state is is fully charged before the
12 hours are done BUT please keep charging your phone for the full 12 hours.
*
3- repeat #2 for 4 more times. This will complete your 6
charging cycles.
*
Your phone will not read the correct battery life until you have
completed the charging cycles.
Please do not stop charging the battery once it reaches
100%.
You may stop charging after the 12 hours have passed.
But it didnt work...

Has any one tried this http://www.amazon.com/2600mAh-Porta...alaxy+S4+MINI+i9190+Rechargeable+Battery+Case
Would the kernel need to be modified to match the mAh of the bettery + case?
And what about this anyone tried? http://www.amazon.com/Power2tek-BAT...rds=Power2tek+BATTERY+3.7V+For+Samsung+B500BE
Thanks,

It might be dangerous
The S4 mini might not be compatable with the other batteries. It might even blast. Better to use Samsung made Or 1900mAH Battery.Because u can't fit more material into same space but if the battery is not Li-ion the storage might increase. Then it might not support the phone .Best to use Manufacture made.

I know this thread is a little stale but does anyone know if there is a comparable version of this change that can be applied to CM12.1? Is CM12.1 capable of handling different sized batteries? I am not sure how to get back to 4.2.2 and honestly I would rather stay at LP than downgrade back to JB so any additional information would be much appreciated.
I bought a Zerolemon 5100mAh battery and from 3 hours of screen on time with the original battery, I get now 8 hours and 2 to 3 days of heavy use, instead of 1 day.
In my case even the battery meter is fairly accurate and when it gets to 0% it actually is empty.
If you want more informations about it, I made a youtube video: "Zerolemon 5100mAh Extended Battery for Samsung Galaxy S4 Mini - unboxing and first impressions"
Feel free to ask anything about it in the video comments section.

OK. So I've flashed 3800mAh kernel version. Now terminal gives me a value of "-414967296". Yes, with "minus" in the front
It seems like you're hitting an integer overflow here.
The maximum value for a 32 bit signed integer is 2,147,483,647.
Default value is 1,940,000,000 (uAh)
* 2 = 3,880,000,000 which is bigger than 2,147,483,647 and overflows to -414,967,296
* 3 = 5,820,000,000 overflows to 70,032,704
So this kernel patch might have unexpected behavior. You might try to convert the values to unsigned int but even then the 3x patch won't fit (BTW there are no commercially available 3x batteries, they are advertised as 3x but real capacity is at most 2x, physical limits apply)

5So I had time to compile some extended battery versions of my vikinger stock 4.2.2 kernel for you guys
There are 3 versions available: 3800mah, 4275mah and 6333mah for the lte and 3g variant of the s4 mini.
You can check the expected battery capacity with adb shell or with the terminal app:
"cat /sys/class/power_supply/battery/energy_full"
it should be "1940000" with the stock kernel and after flashing one of my modified kernels it should be higher.
So here are the download links:
GT-I9195: 3800 4275 6333
GT-I9190: 3800 4275 6333
After flashing the kernel you should calibrate your battery with an app from google play store.
(so discharge below 10%, then delete "/data/system/batterystats.bin", reboot and charge to 100%)
Let me know if it works for you guys.1
is it sure really 2800mAh?
I don't think so...
I used this kind of batteries on S2, but all of them not real capacity that was labeled...1
Hey Guys, i bought one of the battery signed i9192 and 2800mAh. The battery drain was the same like the original Samsung 1900mAh battery, but there was a little problem with the exact size. It is about only a half mm, but it had to push hard the battery to go into it's place.
