New tmo update did nothing. My cell standby is currently at 10%. Back to no VoLTE and Wi-Fi calling.
I don't know why but since this update, both my Note 5s batteries have gone to ****!!
I've wiped the cache, and even resorted to a full factory restore on one device.
My cell standby jumped from 1 - 2 % to nearly 10% in the 24 hr duration!!
SOT went from ~ 5 hrs to ~ 3 hrs now, with everything else the same as was prior to the update!!
Today, I've removed 'Package Disabler Pro', and re-enabled everything (only using Smart Manager) with a full recharge. VoLTE is enabled, and WiFi Calling disabled ( I never use WiFi calling )
So far, unplugged since 11 am (Mountain Time) it's at 97% (3:02 pm now) with only 15 mins SOT and a 10 min phone call.
