Battery STAMINA Mode

How Sony’s Battery STAMINA Mode works

With Sony’s power management setting called Battery STAMINA Mode, you can extend the standby time of your Xperia™ device by more than four times. With Battery STAMINA Mode turned on, the background activities of most applications are reduced when you turn off the screen. Read more on how it works after the jump!

Battery life is a very important factor for many consumers, and this is something Sony has been working hard to improve. We found out that a lot of the battery power on a smartphone or tablet is consumed by background activities in apps and games when the device is not in use. Now with the new Battery STAMINA Mode enabled, apps are not allowed to synchronise and check for notifications and incoming messages when the screen is off, something that normally consumes quite a lot of power while your phone is resting in your pocket.

Battery STAMINA Mode builds on the same technology as Extended Standby Mode, which is available in some Sony smartphones released last year. Starting one minute after the screen has been turned off, data traffic is automatically blocked and background activities are prevented from waking up the system. And then when you turn on the screen, the activities will resume again instantly. And as the IP address for your phone is kept, you will immediately have network access.  This all makes it possible to bring you notifications when you need them and have time to look at the screen, and not while the phone is tucked away.

When Battery STAMINA Mode is on, you will still receive phone calls, SMS text messages and MMS notifications at all times. The preinstalled Calendar app and Alarm notifications will also work as normal, while the LED will only illuminate to indicate low battery.

Battery STAMINA Mode is turned off by default, but you can easily turn it on in the Power management settings.

When Battery STAMINA Mode is running, you will also get power management tips to help you save even more energy, and keep your device going even longer. For example, if Battery STAMINA Mode is turned off and you leave your device with the screen turned off for six hours or more, you will get a recommendation in the notification bar to turn on Battery STAMINA Mode. You will also be notified about apps that consume a lot of power.

Customise Battery STAMINA Mode – white list your important apps
Another really useful functionality, is that you can actually choose to white list your most important apps, allowing them to run in the background even when Battery STAMINA Mode is turned on. This way you will get notifications even when your phone rests in your bag or pocket. This is handy if you still want to be able to receive instant messages or IP calls at any time. So, for example, if you want to have Google Talk running continuously even though you are Battery STAMINA Mode, it’s no problem. Just white list Google Talk and it will work as normal.

You can also set a battery threshold, so that Battery STAMINA Mode kicks in below a certain battery level that you define yourself.

Customise Battery STAMINA Mode to suit your needs by white listing applications.

    Does the apps refresh every 15mins even when the screen is off?

    Stamina mode is supposed to turn data off. But if we choose to put whatsapp in the white list (for example), this means data is always working??

    Stamina mode on my Z2 seems to be doing nothing at all. For example Whatsapp and FB messenger messages come through. So it doesn’t disable mobile data. LED works normally as well.

    How can I unlock my phone that is in stamina mode? It’s my first time to use it in my new phoe sony experia m2, but i cannot unlock my phone anymore.

    STAMINA is a good feature for Xperia, but it has a problem, it turning off mobile network forcibly, even if someone doesn’t need this function. battery saver apps such DU Battery Saver do separate this two feature each other, turning off mobile network and stop background programs, so user can choose which of these features should be on or off. because of it, i prefer to use an app instead of STAMINA.

    Hi, does the “stamina mode” automatically turn on when the battery level reaches a certain percentage level? Or do we have it to turn it on manually every time? Thanks.

    Hi guys, I’m having a problem with my xperia M – more exactly “stamina mode” :) . It worked well about 4 weeks, but since yesterday it is showing “estimated battery time – 13 / 16 days” depending on battery’s level of charge. Obvious, it’s not accurate because it drops “days” in couple of hours, but I don’t know what could be the cause. Any suggestions beside reseting the phone, please ? :) thank you.

      ok, so here’s the thing : I took the plunge yesterday and did a factory reset to my phone, thinking somehow I broke something to android or accidentally deleted a system file (like a log file for battery if there is one) when browsing through the phone. Before that, I did a full back-up in order to restore aps&data after. After reset and restore everything was fine, in “stamina mode” the range was ~2 days&12h which is a correct value and the same to the one shown for 4 weeks. Also, yesterday received and installed two updates : one for walkman, other for movies, and then my problem reappeard :( in stamina mode although the battery is draining, the range is growing, showing 3,4,5 days. Probably if I charge the phone, I will reach the same 13 to 16 days :( . I think the problem is one of those two updates, because I hadn’t this problem before. Am I the only one facing this ? :)

        Exactly this is I am looking for.
        I have the same issue here,For the last 2 weeks I had a good battery back up when I turned on the stamina mode and there was a notification icon showing stamina mode is on (two palms support the battery).
        But last night after I updated the album from Sony,the notification icon disappeared though I have turned the stamina mode on,and the battery didn’t last longer as I had experienced.At 3 am I went to sleep with 42% of batt and then wake up 6 hours later and checked the battery, it showed 22%. Wow…..I am using xperia M2.
        Any response from Sony?

    hi.. I have Sony Xperia C. Firstly, I had only 2GB memory card, and everything was working fine. But Recently, i have bought 16GB Class 10 memory card, and shifted all the data from 2GB memory card to 16GB memory Card, and inserted in my phone. From then onwards, Power Management of my phone does not show the Correct Estimated battery time. If my phone is 100% charged, it shows 4 Hours estimated time, but actual battery time is 1day 4hours. Battery is working fine( no matter what power management is showing, Battery is giving me 1day 4hours backup), but I need power management to show correct power management time. Plz give me the solution.

    Hi there,
    I recently realized that I still get whatsapp messages even though I did not white listed it.
    Is that a known problem?
    Thanks guys.

      Hi Benjamin Zonker,
      I have the same problem with you before. But now the stamina mode on my Xperia E1 dual is working properly.
      The first you must to do is to install pc companion, you can find it at sonymobile.com. And then choose for repair the phone on the up left side. This take about 30 minute for fixing and all your data will erase after that.
      Try to back-up first. thank you and i hope this can help you for your problem issue

    Im using the stamina mode ON all the time on my Xperia ultra Z2. And trust me even after using the whole day the battery still last upto 60-70%. My opinion will be to keep it on. All the best.

      You should see a white plus sign next to the battery percentage icon on the top bar. :D
