Interesting Battery Life comparison on 7 Plus vs 6s Plus

When comparing the 7 Plus to the 6s Plus here:

It's interesting to note that in some cases the battery life has DECREASED on the 7 Plus, such as with talk time, going from 24 hours on the 6s Plus to 21 hours on the 7 Plus, and wireless audio playback is way down to 60 hours on the 7 Plus from 80 hours on the 6s Plus.

It's most likely due to the modem chip used in the new phones vs the old ones. Less efficient power wise.
I think they are using Intel with TSMC packaging. Not sure about BT though.

I was surprised to hear that with both a bigger battery and the new power-saving A10 Fusion CPU, these were all the battery life improvements (along with a some regressions) we were able to get.
