Hey bros,why is it my phone charges and when it says fully charged,but when I look at it using GO Widget,it's still at 97%. Then,I charged it again,then it reaches fully charge status,unplug it,then it goes back down to 98%. Firmware problem or should I take note of this?
I don't think is firmware, maybe you could try battery calibration from the market..
It might work..
But if can't there is a physics explanation, as it is the law of the universe that nothing is perfect, even absolute zero, molecules still vibrate... and everything tends to distortion, ( the uncertainty principle ) ...
One thing is for sure, the battery charger cable itself holds some of the charge, hence although it shows full charge but when you unplug, a fraction of percentage of the battery is still in the battery cable..
Other than that, the battery is not 100% efficient, it's a law by nature to..
Nothing is perfect ( second law of thermodynamics )..
Hence, charging to 100% is also not possible, the manufacturer definitely rounded up to 100%..
But if the market app works then its fine....
