alperdk , If that happened, you probably are not gonna face this problem for really long if you follow the precautions given in the thread as well.
4% drop in one hour is normal if you have a 3rd party app that really uses a lot of power etc. I'd advice you to go through the battery usage chart ( settings > power management > battery usage ) to monitor your apps.

Yes, It indeed is one of them.
Let me try to explaing this briefly. Apps like clean master and similar, stop a lot of apps simultaneously with the press of one button. Now, out of all the closed app, 1 or more apps could be related to the battery app directly or indirectly. When apps are closed forcefully while they are in the middle of something, there's a chance their data may get corrupt. Now let us suppose that the apps closed forcefully was battery app. Now, the sudden break in the process might result in messed up calculations. Thereby resulting in abnormal battery %
One thing to note is, that this problem is related to android and is universal across all companies.
I don't use any apps such as antivirus and task killers and I've never faced any problem related to battery % since I uninstalled them all.

Hi maybe i missed somthing i have Z1 once it arrives around 60% it shuts down
after a short charge it reaches 70-80% again
i tried what you suggested but maybe i missed a step
once the phone is charged just take it and restart it or do i need to disable some process??

After the button combination, you should see a considerable drop in battery%.
After that, just follow the precations given in the thread. You don't have to disable any process or anything, rather uninstall apps that monitor battery % and apps like battery savers, task killers, etc

Wow, I can't believe it!
My phone's been tricking me for weeks and weeks, I was always carrying a charger because I never knew, when it would turn off.
I called the Sony Support and they told me to update my Z1C to Lollipop - which I did yesterday.
The battery worked for more than 24 hours straight with no problems. But today, at 87% it turned itself off.
I put it on the charger and started reading here, where I found this guide, how to solve this problem.
I unplugged the charger (31 % charged), did the forced shutdown, turned it on again and - 91%!!!!
If this really is the solution I needed, I just wanted to say thank you!

It's great that it worked for you.
However do follow the precautions given in the thread. Moreover, doing force shutdown once in two weeks should help as well.

That is Ok. Your battery should be showing the real % now.
The steps you followed help to fix the problem with phone showing inaccurate battery level.
Doing that once in a week would help :smileysmileythumbsup:
