Had this battery for 9 months now and seems im having some issues. The batterylife is still great but charging time is way longer. When my phone is on and charging it shows up as 100% but after you unplug it it goes instatnly to 72%. Doest do a full charge when its on but when the phone is off its fine. Was thinking of gettinga new onw but might upgrade soon anyway so yeah...
You say when your phone is on and charging is shows up as 100%, but drops to 72% when you unplug it from the charger?
Try this. Don't remove the charger as soon as it reaches 100%. Wait for the green led. This might take a few more hours.
My 7000mAh battery usually charges from 20% to full in about 4 hours or so, but I leave it plugged in longer until the battery-full indicator comes on (green led). It does not drop at all when I unplug it from the charger. You might need to clear any other notifications then turn off the screen before you see the green led.
Of course my battery is relatively new so I might experience the same thing you do later.
