my G960F old almost two years now, recently replaced battery for an original new one.

When I plug in for charging, system say that 5% to fully charged will take approx 1h 30 min but battery is on 100% in less than 45 min. Charging with OEM charger and original cable.

Even if replaced with new one, battery is almost empty in 3 hours on screen time but when drop to 1% it may last for an hour of additional usage (messenger, playing music, youtube, etc). Accubattery app say estimated battery capacity is 1800 mAh but original battery is 3000 mAh.

Anyone can help?
