I can't believe that a software update can so severely damage the phone hardware.
I refuse to change the battery with my money until someone's in Sony explain to us why the Lollipop update damaged the battery to many users
Yes, I'm now using CM12.1 to try to fix it, no results.
I can't believe this.
Where are you @Rickard?

checked the thread. did the force shutdown on my z1 compact. battery was at 90%. when i restarted, it was at 82%. so now what? your post does not tell me what to do if the % drop is > 5%??!
i'm facing this sudden battery drain issue. i'd upgraded to lollipop. now downgraded to kitkat. still, it shuts down randomly at around 50% battery and when i restart, it is at 5-6%. what to do?

I'm afraid that the only way to fix this (if it wa a software problem) is performing a Software Repair via PC Companion, this will do a clean installation of the latest firmware and will also wipe your internal memory.
Open PC companion -> Support zone -> Phone/tablet software update -> Repair my phone/tablet (blue link style). Follow the steps given, do not connect your phone until prompted to press volume down while plugging USB cable.
You already tried everything else, and if you send it to a repair center they will start by the same procedure: Software Repair.

I have the same problem that everybody has been complaining about. I contacted Sony, which told me to repair my Z1c by using PC Companion. I did that but, so far, the problem continues. Now I noticed there is a new firmware version: 14.6.A.0.368. Has anyone updated to this version? Does it solve the problem?

Another thing I've noticed is that, even though my wi-fi is turned off, if I check my battery history sometimes it appears as it was always on. Maybe it's a problem with wi-fi?

Just to inform everyone that the battery % drop is still alive in 5.1.1 even after pc companion repair. Will change battery mnyself and report later.

Its cause is Lollipop, Device is getting hot in Android 5.0 and shuting down. I have the same problem. I advise you to downgrade Kitkat
