At the end of last March, the Sony flagship received its latest software update. But apparently, some users begin to see that one of the strengths of the Sony Xperia Z has begun to not work after the latest improvements. And this function is the STAMINA mode, the one in charge of optimizing the smartphone's resources to the maximum and that it does not make excessive use of the battery. In short: that their autonomy is greater.
Sony presented the STAMINA mode as the only solution to achieve a reasonable battery life. Furthermore, according to the data provided by the Japanese company, users would get up to 400 percent more autonomy, depending on the configured parameters. How is this function activated? Entering "settings", you have to activate the STAMINA mode, and there you can mark the applications that you want to disable when the smartphone enters sleep mode.
Among the many options that Sony offers, you can disable SMS, MMS, email or calendar notifications. As for connections, WiFi, GPS or Bluetooth may also be disabled. Although be careful, all of them would work again as soon as the user began to use the equipment again.
However, all this seems to have stopped working after the last update that was released on March 25. The numbering for these improvements was 10.1.A.1.434. But be careful, it is not that you cannot activate the deactivation of the applications or enter the STAMINA mode menu. Apparently, some users have noticed how after starting the battery saving, the figures do not follow as before. In other words, there is no improvement in battery performance.
We must also remember that it is not the only company that has had failures after a new update. The clearest example in recent months has been Apple with its iPhone 5. And battery saving is one of the pending issues of those of Cupertino. Although in the case of the company with the bitten apple, these improvements could come in the form of a new full version of iOS "" its own mobile platform "" and the arrival of a renewed iPhone 5S. All this in the month of June.
Meanwhile, from the Xperiablog portal they have commented that the test unit they have in their possession has suffered the same problems, so they hope that Sony is aware of this error and will soon put the solution on the market through a new one. improvement, for which it is the first smartphone of the Japanese with a quad-core processor, with an improved chassis and resistant to both dust and water. As well as a five-inch diagonal Full HD (1080p) screen.
Of course, the Sony Xperia Z bets on Android as the latest releases on the market. Although this model already enjoys Android 4.1.2 Jelly Bean, one of the latest versions of Google and possibly in a few months it will receive the latest numbering of the green android icons.
