I charged it over night (phone on), then when i got up in the morning i turned off phone upluged the charger, and then repluged charger, with phone still off waited until battery meter stayed steady green(about 5-10min), full charge. Unplug phone, repluged phone watched battery metter again until steady green (about 5 min). Then turn phone back on and bam over 8 hours of 100%.
Now i would not recommend doing this every single time either
It is now 16 hrs 18 min @about since doing bump charge, and a long phone call with sister (about 30 min) am at 88%
