I have only had my Yoga Tab 3 Pro a couple of months, so I contacted the reseller that I bought the tablet from here in the UK. This retailer is a large national store and I spoke to their technical department. I was told they, and Lenovo were aware of the battery issue, and that Lenovo was working on a "fix".
It would be good to know if that was true?

Please post here the response when you get it. I have not sent my Yoga Tab3 Pro away for repair until I know there is a solution to the problem.
Which country did you have to send your tablet to?

Hi folks - new user. I just bought a Yoga Tab 3 Pro through Amazon a few days ago, and unfortunately before I found this specific thread. I read lots of customer support horror stories before I purchased, but since I've read similar customer service stories with several big consumer names these days (Samsung, LG, Moto, Comcast, DJI, etc...), I figured I was going in with my eyes open.
I have the 4G/Marshmallow version, and like you, it only reports a 4300mAh battery through battery apps. This issue bugs me, especially if there's the possibility that the OS isn't using the second battery. I'm assuming that since it's been this way since Android 6 was deployed (or at least since the April update), Lenovo has no interest in fixing it. That said, is there a way to be SURE that the OS is using both batteries?
I did the engineering setup thing, and it does appear to report, and show charging and discharging of the second battery. In addition, I just ran an overnight test (first charge and discharge) and got about 10.5 hours of video with the Xfinity Stream app. I only had Plex and the Xfinity Stream app installed, removed a bunch of bloat (McAfee, docs, sheets, and a few others, disabled a bunch from auto starting and rebooted). I also had bluetooth off, adaptive brightness off, and the screen at about 5-10%. It's a FAR cry from the 18 hours printed on the front sticker, but not inconsistent with the reviews (most for the 2G/32G model).
When in engineering mode with no apps running in the background, it seems to use about 400-500mA (150-200mA from the main battery, 250-300mA from the SEC). I haven't tried going into eng mode with the Xfinity app backgrounded....even then it might not be accurate. So is it safe to say that mine is utilizing the full 10,200mAh? It just feels like 10,200 should last MUCH longer.
Thanks for any pointers...
