Hello, anyone "upgrade" from 6 Plus 5.5" to 6s 4.7" ?

My wife is using 6 Plus currently but she thinks it's too big/heavy for daily usage, hower she is still very happy with the battery life which is quite a big advantage, just the phone size is quite big.

I wanna ask how's the 6s battery life? I know it definitely not comparable with 6 Plus, but i just want to know how poor it is when come to this unfair comparison.

Thanks .

Awesome! Thanks for sharing.

How was the setting throughout the usage? Such as screen brightness, Bluetooth on/off, etc?
