there was a good explanation as to why this is he case posted somewhere else on the forum which I'll try to dig up, but suffice to say that there IS a reason to do with the newest architecture and while I agree there probably was a way to fix it, it's better to remove it while it's completely inaccurate, and re add it later if they fix it. Relying on that indicator on this specific MacBook was useless.
Got a tip for us?

May I ask what battery indicator that is? It looks much better than the ones I tried
Apple figures that if you don't see something that indicates the battery life sucks then you might not presume the battery life sucks or sucks as much. Thus, the perception of the battery life sucking is minimized even though it may still suck. BRILLIANT!!!

Battery life was already good on my 13" tbMBP prior to the update. But it seems even better now. Before I was getting 7-9 hour battery life based on 10-20-30% actual usage. Now I have just spent 2h30min on battery spending less than 20% of battery capacity, so on track for more than 10h. Safari (80%) + youtube + streaming live TV channel.
Is there anyone else seeing improved battery life with 10.12.2 final?
I will install tonight and test tomorrow.
UPDATE: I just installed and unplugged, and I've been using it for 20 minutes and am still at 100%. Yes, I get that estimates are not accurate, but this is definitely different than before. I've been watching power consumption in Battery Health 2 and it does seem lower.
That said, something similar happened after I reinstalled Sierra. I got 8-8.5 hours for a couple of cycles after that, but over time it dropped to 6-6.5 hours. So far too early to celebrate.

Update for me: The final version of 10.12.2 fixed my issues! It using the appropriate wattages again. Coconut is showing 10 plus hours remaining after 30 minutes of my average use style. (per Battery Logger 2). I did the install plugged in, then let it sit for a couple hours plugged in so it would finish re-indexing and all has been good since. Very pleased.
I just upgraded to 10.12.2 -- been using it mobile for about an hour. Initial impressions: Wattages are not better for me, I'm still on pace for about ~6ish hours from web browsing/music/non-high performance apps, less than 2/3 brightness. Not sure if my computer is re-indexing (but Spotlight shows no activity in Activity Monitor). Will update if this changes.
Talked to a tech at Apple today while I was getting my phone repaired. They (Apple) are totally aware of the situation and believe it has to do with the kernel tasks that's doing something weird with Sierra. Though they think this recent update should show some improvement, it won't be until the next update that will show a significant improvement in battery life. Right now the staff have been told that all they can do is wait for a fix within the next update. The tech also stated that it's not a hardware issue. Hope this brings some light to people.
I did some researches on the required specs and ordered a bit hurriedly as needs to wait for 5 weeks, yah the battery size was missed.
I heard something similar from Apple tech. They're waiting on the next update to address the kernel tasks that's sapping the battery. The batteries are normal and it's not a defect. The only defect they have seen is with the dGPU units so far on the motherboard.
Uploaded my hardware report this morning to their support website as requested by them during a 2 hour call. Let's pray...
Macbook 15 touch bar 10.2.2 if u do smc reset the laptop will not turn on. It stucks in apple logo and the fans go crazy!!
Ok it is official. New update 10.12.2 fixed my battery I am up back to 9-10 hrs of regular use. Before update idle power consumption was not going lower than 6W, after 10.12.2 it is now < 4W (60% brightness, ALS on).
With ~50Wh battery, it translates easily way over 10 hrs (if you are not doing much apart from safari). To get 10 hrs MacBook must average 5W (second attachment) - I get 5.3 Watts Safari browsing, mail, Fantastical2, Bear, Snappy and more apps in background.

Thanks for the update @lobo1978. I am also seeing better battery life with the new MacOS.
Let's talk about discharge while sleeping. I just measured a 3% discharge, 150mAh, after 8h of sleep. That would yield 10-12 days for s standby time or less than 50% of Apple's estimates. I don't see it as a problem but hopefully this can be improved on the next MacOS update.

Can report similar results. I am now getting better battery life even with 75% brightness.
Yep, seems to be the same for me, I haven't tried it above 50% brightness but will try that today
I didn't really have any battery issues to begin with but the new update definitely didn't create any which is nice. I still seem to get about 10 hours browsing with a 15". I haven't used the computer too much since the update but everything seems to be working well and seems stable. Glad to hear it's helping out with a lot of your issues! When I heard some of the wattages being talked about I really thought something strange was going on in software so hopefully that is true and they are resolving it.
That's what I'm seeing and seems to be reported on the forum too. It's not ideal but can live with 10 days for now
