So i tried the 10.12.2 beta yesterday thinking it'll have the newest graphic and touchbar fixes (safari sometimes leaves some corruption on tabs). And it kinda did (they made the touchbar animation a little bit cleaner).

But it also messed up my battery hard. The icon will no longer tell you how much time you have left, just a mythical Power Source : Battery. Activity monitor will give you a really low estimated time, and the battery seems to go down like crazy.

I've confirmed with a different user in the EU owners thread that my BootROM is updated to MBP133.0226.B07, and I'm placing the bet that that's where the problem is at. Reseting the SMC, nvram or going back to 10.12.1 doesn't fix the problem.

So yeah, don't do that. Hopefully the next beta or 10.12.2 release doesn't have this issue and it will fix mine

Edit : My specs are 2016 TB 15', 2.6Ghz, Radeon 460, 512GB SSD

I can a 100% confirm this. I updated to the Beta and yesterday evening my 15' battery would go down by 20% in half an hour doing nothing! No estimated battery time showing. Going back to normal didn't do any good. I am baffled ...

OH BOY I really did not expect that you can make the MacBook experience even worse than it is currently.

Did you try if iStat Menus shows remaining battery life properly?
No, I don't have that app, I use coconutbattery. I somehow made it to work okay, with multiple smc reset attempts (I seriously HATE how this all works now). That said, I still get no graph in activity monitor and all of this just works weird.

The times are different because the apps poll at different intervals
[doublepost=1480687953][/doublepost]And here's the activity monitor screwing up, back on 10.12.1

It updates your bootrom, that resides in the firmware. Abd before you ask, no, you cant downgrade :(

Not Sure... no issue here. I have 10.12.2 beta 4 on my Macbook Pro 13" TB. Doesn't seem to have an effect on battery... I'm getting the same battery as before the update (relatively poor compared to the "10 hours" promised). And my battery meter seems to function fine.

Can you show me your activity monitor on the energy tab? And list your firmware version for SMC, BootRom and Battery?

My battery has taken a dive since the latest beta. Oddly, unchecking automatic graphics switching uses less power on the dGPU than the iGPU. Figure that one out! I show 12w at idle with the dGPU and 20w when switched back to the iGPU. After a reboot the iGPU is showing 8w, which should be about normal, but then it suddenly jumps back to using 20 plus watts while still keeping idle. Screen brightness was just past 50% in these screenshots.
