I am charging a mobile phone 1150mAh battery and I have the option to charge it via USB (500mA which would be 0.43C) otherwise using its AC power adapter (which charges at 900mA which is 0.78C).
For those who don't know, a 1C charge would charge a battery in 1 hour (at 1150mA constant current), where a 0.5C charge would do in 2 hours (1150mA/2 constant current)
Can someone tell me which one of these charging methods will give me the longest "runtime" after the charge if I were to drain the battery down to nothing?
I am aware higher 'C' rates decrease lifespan of battery, but I'm only concerned about runtime for now.
