STAMINA mode dead?

[romuloch]

Ok... I have to sai I'm starting go get mad about this phone, but here we go (another issue).

I have a BR branded Sony Xperia ZL (C6503) Build 10.1.A.1.350 with Android 4.1.2 - update not available yet.

Yesterday I went to sleep with 96% battery. ~6 hours later, in STAMINA mode, battery has died.

Now, I have just turned on and find out that this darn functionality is not working and THIS freaks me out. I mean... in BR, this cost me ~1k USD and it keeps giving me headaches.

As you can see in the image below, all options are ON and it happens that nothing changes.

Anyone has a clue?

You said it's a brand new phone. How long? 1 day? 3days? Cuz it makes a different.

When a new phone (or Android) starts the first time, it does alot of backgroud activity to index,profile & calibrate the phone. This process works in the backgroud and will take a few hours to complete.

My suggestion, is to update to the latest software and used it for a few days without restarting the phone in between. This will ensure optimum battery calibration. After that, the phone should work normally.

As I said "I have a BR branded Sony Xperia ZL (C6503) Build 10.1.A.1.350 with Android 4.1.2 - update not available yet." I can't update without losing warranty. Also, it's a one month new phone.

It was working until yesterday.

Btw, I'm a heavy user. But there's *no changes* swtiching ON/OFF.

Is nothing with yours mobile phone. Not need to worry. I had the same problem. For example i had 20% battery and was showing 10 hours in power managment with stamina on or off. My solution for that is do reset settings or repair software by SUS or Pc companion
