It is now blank as in

Time since last full charge

Usage --
Standby --


Already tried resetting and charging to 100% after full drain
 
I did, I upgraded to to the latest update. And I let it charge to 100%. I will let it drain completely and charge it back up again and see if I get the same results.
 
same here on my 6+. Upgraded to 8.1.1 and usage and standby are both blank and it says it will be updated after the phone has been fully charged, even though it stays blank after a full charge.
 
Funny I was just looking at mine and its blank too. It had a full charge cause I charged every night to 100%. Im on 8.1 JB

Well did you respring to install or to update a cydia tweak? The battery usage doesnt work after a respring until its charged again
 
I'm having this same issue. Is it an iOS 8.1.1 bug? Hours after I take it off the charger the usage and standby stats disappear. Sometimes right after I take it off the charger it is blank. Kind of annoying.
 
I have this issue too on my jailbroken iPhone 6. But, it will only happen after respring, hmm.
 
This happens always on a Cydia respring on jailbroken devices. Probably because the phone thinks it has just been rebooted.
 
Not jailbroken...

No jailbreak on my 6 and I have the same issue. It only happens when I shut the device off for a few hours and then turn it back on. Sometimes the stats stay and sometimes there gone. Very annoying!
 
I've had this happen before. I just ignore it and it eventually "fixes itself". I realize that isn't terribly helpful, but at least know that it shouldn't be forever.
 
Has anyone had any luck with this resolving on its own or is there a fix? Currently on the latest version of iOS and still have the issue where battery state show up blank after powering the phone off.
