So your telling me you are following his procedure? He is 72yrs old and probably has all the time in the world to plug his phone in the charger every time it goes to 40% but we have jobs etc and dont have time to keep plugging our phones in the charger at 40% or bring our charger with us all the time! His post is ridiculous! Hey guys try to never let your phone get below 40%.... Seriously?!? 99% of people in the world im sure dont charge there phones at 40%.
He states= You use the phone until it tells you to charge the battery, right? Wrong. Try to never (except, as you'll see later, during conditioning*) let the battery get below 40% charge. Letting it get below 50% is where the lifespan starts dropping. 40% won't shorten the life enough to matter. 20%? Half the life. 5%? The battery probably won't last a year.
These are new batteries and they aren't how they were years ago and don't need calibrations i guess i just got use to doing my method from years ago but honestly i should stop cause it shouldn't matter its 2015.
