Im sure my opinion is a little less worthy than others, but yeah its just simple math here:
Comparing the TB to the NTB model, drawing off the battery:
- 2 fans (instead of 1)
- 28w CPU TDP (vs 15w)
- 23w CPU TDP-down (vs 9.5w)
- Speakers draw more amps than previous models (correct me if i should say watts) - meaning speaker audio may have a larger impact on battery life
- Speaker speculation - since there was less room on the TB model, it might pull even more amps on speaker to compensate for the smaller bass enclosure
- Touchbar display
- Touchbar CPU circuit board
- Higher performance GPU
- 2 additional TB3 pipelines
All with a smaller battery
Honestly - unless someone else has a theory, my thought is Apple ****ed up.
Worst part is - they had to have known this prior to launch.
What should apple do? If they cant magically fix this they should:
*Redesign the unit to accommodate a bigger battery
*Offer a 13" TouchBar trade in program when the revised models come out
*Start listening to their customers
The best news of all for any Touch Bar owner is this - you have the holiday return period till January 8th, 2017. They might be able to fix this with firmware magic - but im skeptical, for good reason.
Recommendation - pickup a non-touch bar on a holiday/black friday discount. I got Best Buy to pricematch a base model space grey for $1299. keep it in the box (know the return period) - you can always return the ntb model if Apple gets its **** together.
