Hmmm… I've be overnight charging in my wireless charge pad instead of my turbo charger. So do you think that could be part of the problem? I'll try charging it with the turbo charger tonight to see if battery is any better tomorrow. By the way, could someone PLEASE explain to me how to imbed a screenshot into a post? I can't find any instructions. Thanks!
There is little doubt in my mind that the wireless charger is at least partly responsible for your results. However I would still do the full powered off charging with the supplied charger, in your case the Turbo Charger, to 100% in order to be 100 percent sure that the battery is getting 100 percent of a charge, and no pun intended.
One thing that can in fact fool the meter into thinking that the phone's battery is fully charged is the temperature of the battery. As the battery heats up while charging voltage levels are rising at the same time. A cold battery won't reach as high of a voltage nor will it reach as full capacity as a warm battery will in the same timeframe. Also a cold battery won't produce as much power in the form of voltage and current as a warm battery will while being used, and anyone that has had a battery fail in winter time in their car knows this first hand.
However more importantly, a warm battery will show higher voltages at the end of a charging cycle than a battery that was charged slowly and cool and therefore the warm battery can be interrupted in the charging cycle by the meter sooner than it should have been, whereas the battery that was charged slower at the end and at a lower temperature will get a better saturation charge, the ending point of the charging process.
Since the Qi or other wireless charger isn't directly connected to the phone in response to the battery temperatures, the wireless charger can in fact heat the battery up more than the stock charger, even when Turbo Charging.
It has been reported that as much as 30% of the power consumed by wireless chargers is wasted in the form of heat. Since the phone is laying on top of the wireless charger, that heat is transmitted upward and into the phone, and in fact the first element of the phone that it hits after the case and the wireless charging coil is the battery itself, so the battery takes the brunt of the heat.
This excess heat will also age your battery far faster than it should. Manufacturers tell you not to leave your phone on your dashboard or in a closed car parked outside for just this reason. So I say try not to leave your phone on a hotplate (wireless charging plate) either. If you must use a wireless charger, put it in front of a fan to increase airflow across the phone helping to dissapate the excess heat and keep the battery (and other components), cool.
