I don't think Note 4 battery will fit
Note 7 battery :
37.9 mm x 97.8 mm x 4.9 mm
37.4 mm x 97.2 mm x ~5.0 mm
Note 4 :
41.38 x 97.8 x 5.6 mm
Note 7 battery housing is :
38.4mm * 99.2mm * 5.4mm
The best bet so far is Galaxy S7 battery or the FE. I will order a S7 battery right now
Hi , yes I installed a battery from Samsung Galaxy S7 . Fits perfectly.
I used Note 7 pcb battery to solder onto the Galaxy S7 battery
Works well so fall. One change lasts all day.
