when you guys received your Note 4, how long did you charge it the first time and did you use the phone first thing out of the box in order to drain the bit of battery life, then charged it or did you charge it from the get-go? the online manual states that you should charge the battery fully before you use the phone for the first time... just want some opinions please. my wife's S4 was charged first thing for 12h and her battery life is much better than my S4, 18 months on. i used mine out of the box until the battery died. i then charged it for 5hours and that was it. now, she still gets to 50% at the end of the day (using it much more than me) and i get to 10%-15%... is this really a battery issue? how sensitive are the Samsung phones for signal searching and does this affect the battery heavily?
Your wife's phone has half the display resolution of yours, much less pixels to push - of course she will have the edge.
The modern batteries does not require the old 1990s "first charge for 16 hours" nonsense anymore.
Use your phone until battery is at 10%, plug charger in, unplug charger when phone is fully charged.
I'm actually abusing my battery quite a bit (unplug it before it's fully charged, do short charges, etc), that's why I have a brand new spare one in my drawer for when the current battery starts malfunctioning.
Easy peasy.
