Went back to ATT store to give the LG V10 a second look
Conclusion:
I probably would not realize enough additional value over my Galaxy Note 2 to justify the time to migrate (or the $700) given its
- primary use case of Google Maps ++
- next most important use case - phone #2 after iPhone battery < 10%-20% left
- not important but FUN use case of IFE

without needing to consider recharging it once I land
Am kind of bummed. Instead I should be happy that the Note 2 has been such a great value for so long.
Maybe the V2 or V3 generation of fast charge Android phones will eliminate the need for replaceable batteries

Till then, I'll use a 45 second full recharge trick
(replace the tiny battery with another fully charged tiny battery.)
