New Stamina Mode on Xperia Z5 Series really isnt the old Stamina Mode?

For about 4 years Sony's STAMINA mode has been a popular feature of the Xperia smartphone line. It was the best features supplied by Sony. People used to buy Sony handsets because of these features. Sony Stamina Mode limits the background processes and all the apps from accessing the Internet while the handset screen is locked. This stamina mode improved the Xperia battery life, and it helps Xperia to reach their “Two-day battery life.” Also, Sony's Stamina mode offered a white-list option, where users could add the apps which they needed and didn't want to be limited by the stamina mode such as the chatting apps, emails, etc. As a result Stamina mode was a real deal to an Xperia user.

But anyhow with Android 6.0 Marshmallow, Google included a very similar feature knows as the Doze which was baked into the operating system. So OEMs cannot remove these features as it was cooked into the system. Doze mode does a very similar this as the Stamina mode, but to trigger Doze the phone has been in standby and stationary for a while. So because of the Doze, Sony had to remove their beloved Stamina mode to prevent duplicate features.

With the move users were not pleased as the Doze mode only triggers in some minutes after the phone has been resting – leaving it on the desk at work, or on the nightstand when going to bed are perfect examples. So the apps are free to do as they wish and download packages from the Internet at whatever intervals they see fit till the doze mode triggers. So the battery life with the Doze mode was not good as it was with the Stamina mode.

Sony took the users feedback and promised to bring back the Stamina Mode to Android 6.0 Marshmallow. And they brought back the Stamina Mode for their Xperia Z5 series first. But is it really the old Stamina Mode.

As PhoneArena suggests, It's not the old Stamina Mode. Sony has just changed the name of Android's native Power Saving mode and called it Stamina Mode. Check below.

•  New Stamina Mode does not function like the old Stamina mode was functioning - Old Stamina mode would only limit the background processes and the apps from accessing the Internet when the phone was in standby. But with the new Stamina mode, it limits the display brightness, animations, vibration feedback, GPS, and we are warned that background data is also restricted. 
• There's no White-list option to add the apps which users didn't want to be limited - So you no longer can control the apps subjected to the stamina mode. 
• Keeping the new Stamina mode on always is not a better option - There's an option to keep the new Stamina always on. But can we really use it with limits the display brightness, animations, vibration feedback, GPS etc. It will definitely hamper your experience. But the old Stamina mode was barely noticeable when turned on and it can be used all the time.
