In my device the stamina mode stopped working some how when i was watching youtube videos. i got a message saying that your device is using too much of battery, charge your device now (something like that). then i took this scrren shot. my device has the latest updates. This happened only twice, and i had to restart my device each time.
I'm not sure what you mean, could you clarify what the problem is? And the message that you received, is it not the message for low battery and that you should connect it to a charger?
Was your phone very hot when you got that message?
Does stamina start if you set it to always? I suggest you give it a try and reset stamina mode: first disable it,go to settings-apps-all-eco mode controller,force stop and clear data.Restart the device.
It might be related to some task killers,battery savers that you could be using (if any).
i am not using any third party software except for calculator.
Do you want to try a software repair?
