Hello,
I am running CM13 on my S4 mini. Everything works almost flawlessly. Except one recent thing, which doesn't let me sleep at night.
Recently i purchased a battery replacement for my device. The stock battery's capacity was 1900 mAh, which was not meeting my personal requirements. I decided to purchase an extended battery pack with 3800 mAh capacity, (signed as a replacement battery for this particular model) with a special casing to fit the new size. That's where it gets interesting.
First thing i did, i put the new battery inside and switched the device on. The percentage was about 24%, so i plugged in my AC charger (the same that came with the mobile), and left it alone to charge all the way up to 100%. Everything went ok, no extensive heat, just stable charging.
Afterwards i unplugged my phone from the external power supply, and I went outside. The battery dropped to 0% after a few hours. I calculated the power usage and compared with the battery's capacity. They didn't match at all. While the device was off, i plugged in my DC car charger. And as soon as the battery indicator showed up, it said 44%. I unplugged the charger and booted the system. Now the system power indicator also showed 44%, even though it was 0% 2 minutes before.
So i came to a conclusion - the OS is doing something wrong. Question is - what? I started troubleshooting. I checked the system and device status. Everything normal, except one thing - the phone still shows that it's running on a 1900 mAh battery. I wiped cache and dalvik cache partitions. Problem didn't go away. I deleted the batterystats file, even though i know it doesn't matter. The problem still persisted.
But the only thing that showed proper values, was the indicator running while charging without the OS running. So i reversed the situation. I let it discharge to 0% in the system and made sure it's 0% before system boot also. Then i let it charge with the system off. It reached 100%. I unplugged it and booted the android. It showed 66%. I repeated those steps until both the pre-boot and post-boot indicators showed equal values. But unfortunately it didn't fix the issue.
Can anybody help me find some kind of a solution? There has to be a way to get it working, i just don't know where to look further.
Thank you in advance for your advice.
