Now-a-days I feel My Phone(1) is charging slowly than it was few days before. I installed accubattery and it showed approximately 18W while its charging. I mean previously it used to charge in 1hr to 1hr 15min but now its taking more than 1hr 45min. Why its not supporting its peak wattage, is it because of aging of battery or problem with the adapter? Also tried with other chargers than nothing original charger and its still the same
