Recently my phone hasnt been charging to 100%. It stops charging at 67%. I've tried unplugging the charger and plugging it back in to try and boost it but nothing. Ive also tried removing the battery and cleaning the contacts but still no difference. I know its not reaching 100% as I have Android Booster Installed and a symbol appears when its fully charged and this hasnt shown for a few days now. Anyone know whats up with my battery or phone??
