A little battery logging daemon for iOS, written mostly in C but with some Objective-C here and there.
Maninly because:
- I'm curious about how iOS calculates its "Usage" stats
- I want to provide something similar to the Android's "Screen usage" statistics
- I'm having fun doing some "raw" C coding
So, here's my method to calculate the real device usage.
Right now, the only way to really use this thing is to manually start and stop the daemon from MobileTerminal/SSH.
The daemon will correctly flush all the buffers and kill himself if a SIGINT is issued, and it writes its PID at ~/.batterydaemon.pid (the PID file), to ease the stop process.
I will provide a simple application to start/stop the daemon soon.
The Makefile is able to produce a debug and release build: the default target is the first one.
# to produce a debug build
make
# to produce a release build
make release
Then upload it via SSH to your device.
A .deb package will be provided soon, while a sample log can be found here.
