Thank you Nolramlb for your help,
I'm system engineer on NT/Linux system, a few days are enough for my to understand the operation of this unit and set it correctly.
On your URL link, only 2 are realy useful for my (the last two). The only function that I had forgotten to set is:
Get into phone settings > Security > Apps with usage access >
When I woke up today, my phone battery was fully discharged. I will make you a screenshot as requested later, just for fun, because in fact I have already reported to you all the necessary information.
The problem I have is that the function been removed the Stamina fonction of Android 6. I can understand Stamina was not compatible with Android 6, but Sony should have waited to make it compatible before distribute Android 6 for the general public. It is a serious mistake on their part to have done so ! This causes frustration and anger of people who bought this phone as me...
Sell a beautiful and fully functional phone on Android 5 and make almost unusable with the updated Android 6, it is disrespectful of customers who trusted this brand !! I hope it will never be so in the future...
My first instinct was to contact the support center to which you refer, they told me they could do nothing for me and gave me the address of this forum. It is worthy of a very bad customer service.
On the other hand I dont want to or have to send it for repair or to perform an unofficial downgrade, I do not want to damage the phone or lose warranty. Since this update, I Regret this purchase and I would like to obtain a refund and back to Apple with which I have never had neither worries nor need to break my head to administer my phone. I have enough work with my computers... This is a very bad experience that I realize there with my first Android phone, I never think a buy one in the future in view of these problems.
Best regards.
