'One issue this may cause when using an older battery is if you have too many exclusions, the phone stays active longer during wake periods because the battery cannot provide full power flow thus making the CPU work longer. This is not a problem in newer batteries with max power flow capabilities intact, allowing the CPU full power and finishing on time. '
ChanChan, I tried to pm you about the above, but on tapatalk you are unable to receive. Give me a pm if you would like clarification of your battery explanation.
