Lumia 950 battery drains rapidly

Here is all I did and seem to have helped:

1. Changed my email sync setting to every 30 minutes on all accounts.

2. install the update with  reset.

  its doing better but not meeting the expectation based on product details.

Here are two more anecdotes about how bad the battery drain issue is (.29 update installed, no reset/reinstall):

Yesterday I charged the phone over USB while trying (not very successfully) to get OneDrive to upload a few photos from the Camera Roll. Not fully charged, I removed it and went outside, noting that it was very hot, draining battery quickly. I shut down all apps and continued for a while, but the phone kept burning my leg, now almost fully discharged. According to the Battery app, it was consuming > 20%/hour. I restarted the phone, and battery usage went down to 3%/hour (which is still too high for a new phone in Standby).

This night, I charged it in a QI cradle, but in the morning the phone was hot and had a completely empty battery. Looking at the charge graph in the Battery app, the phone had apparently started drawing power like crazy again after reaching full charge, until it shut off after 5-6 hours.

You can see the two "incidents" in the screenshot below:

According to the built-in battery statistics, the biggest culprit is the screen, and the most power hungry app is Edge. However, I don't trust these numbers, since they indicate very little power consumed from background activities, when I have only used the phone very lightly the last 24 hours. The complete discharge last night happened when the phone was left in the QI charging dock and I was sound asleep (dreaming of a vibrant mobile app ecosystem). Anyway, here is a screenshot (sorry for the Swedish):

This is bad. Can we have some confirmation that Microsoft is looking into this? The Lumia 950, considered a "flagship" with a price comparable to an iPhone 6S, is basically garbage with this issue unresolved. According to Microsoft, it has a talk time of 18 hours and a standby time of 12 days. These are lies of Volkswagen proportions, when even standby time is less than 18 hours. (Add to this the catastrophic state of the OneDrive "integration" in W10, and I wonder if anybody in Redmond still cares.)

A full rest would not hurt b, just the .29 update is all you need. I never did the factory reset. I'm on day 3 after update and pleased with my phone now.        

I think I needed the reset in order to get the .29 update. Before that the update check showed "all current", and after the reset the update came through with no problem. The phone has been working great since.

Update on my issue:

After update to ver. .29, battery improved mildly.  However, it still drained with minimal usage.  At night, it wouldn't even fully recharge on my wireless dock.  However, I turned the phone off then on, and that improved battery life.  It's like the processes accumulate as the phone runs, and really start wearing on the battery.  By turning it off, I dumped a bunch of those.   That, or Msft fixed something on its end.

Today, I took the phone off the charging stand at 6:30, and at 3:30, I have 65%, with email coming in, and some mild usage.  In the past, I'd be at 40% or less.

Yesterday I have the same problem, the only way I found is to reinitialised the phone, not restore data, and reinstal all manualy, now Phone is ok
