Hi @Battert,

Welcome to the community.

There is no official way to return to a previous version of Android I'm afraid. Are you experiencing issues with the latest update?

[Battert]

Yes the battery life time is too short.. Iam really annoyed! How long does it survive with you sir?!

@Battert,

I just saw you made 3 posts. I have moved them all here to simplify it a bit. 

If you are experiencing battery drain issues after an update it could be due to apps updating to be compatible with the new firmware. Make sure all your apps are up to date then charge your phone to full.

If you are still experiencing the same issue, use your phone until it gets to 10% then go to Settings > Battery > Show Battery Usage. 

Make a note of how long it took to get to 10% and please take a screenshot of this page in your phone and post it here.

OK thanks alot..
But I want to know what is the ideal life time for the battery from 100%to 0% please?

@Battert,

It entirely depends on how you use your phone so I cannot make any accurate assumptions without first knowing this information. With normal usage (some texts, some calls, some browsing etc) you could expect a day or more.

With heavy usage, much less. The longer your screen is turned on, the less time your phone will last before needing to be charged again. I would expect about 4-6 hours of on screen time, depending on the brightness level and the apps that you are using.

I have done as you said and the battery extended for 4 hrs from calling and 2 hrs screen on
Is sthat good?

I cant put a screen shot here

@Battert,

Yes please, show us the screenshot. It will help identify where the problem might be.
