Sony says STAMINA Mode is back with the latest Xperia Z5 update, but it really isn't. Here's why


Sony's STAMINA mode has been a beloved feature of the Xperia smartphone line for years now. It limits background processes and apps from accessing the Internet when the phone is in standby, drastically improving battery life and helping the Xperias reach their praised “Two-day battery life”. The feature also offered a whitelist option, where the user could include the apps they didn't want to be limited by STAMINA, such as chat apps, business emails, et cetera. As a result, one could keep STAMINA mode on at all times and get all the benefits of the extended battery life with no apparent drawbacks.

However, with Android 6 Marshmallow, Google baked a very similar feature right into the operating system. Called Doze, this new code kicks in after the phone has been in standby and stationary for a while, and it does a very similar thing to Sony's STAMINA, limiting Internet access and saving lots of power. In order to prevent duplicate features on its smartphones, Sony removed the beloved STAMINA mode.

Users were displeased with this move. The fact is that Google's Doze mode only kicks 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. For the rest of the time, apps are free to do as they wish and download packages from the Internet at whatever intervals they see fit. As a result, battery life under Doze mode was noticeably not as good as when STAMINA was active.

Sony took note of user feedback and promised that STAMINA will return with the latest Xperia Z5 update. And return it did, but is it the good-old STAMINA we've come to know and love? Drum roll, please!



No, no it's not. In fact, at plain sight, it looks like Sony just changed the name of Android's native Power Saving mode and called it a day. Here's why:

  • The new STAMINA mode does not function like the last one did. Before, it would only limit background processes from accessing the Internet when the phone was in standby. Now, STAMINA limits display brightness, animations, vibration feedback, GPS, and we are warned that background data is also restricted at all times.
  • There is no whitelist. On the topic of background data – you no longer have a choice of apps to be left unscathed by the limiting.
  • Keeping the new STAMINA mode on at all times is no longer a viable option. While it is most certainly allowed in the settings menu, keeping it constantly on will severely hamper your experience. In contrast, the old STAMINA mode was barely noticeable and any Xperia user was used to just have it on at all times.

Check the screenshots below to see how the Xperia STAMINA mode used to look before, and how very similar it is to Android's Battery saver now. Disappointed?

Sony loves leaving their users wanting more.

Way to be super defensive. Sony lied about bringing Stamina Mode back. I'd be pissed if I were a Sony user. Stick to talking about the article, not your personal problems. :)

Way to be super evasive. "Stamina mode" is a Sony branding nither you nor PA get to decide what kind of name they use for their features. Yeah, talk about personal problem, ha ha, such a hypocrite you are. You have a problem with Sony that's why you jump any chance to post negative comment about Sony.

Looks like someone didn't read the article and quickly jumped to the comment section. Not surprised at all. In case you skipped the reasoning behind the article, here you go: The new STAMINA mode does not function like the last one did. Before, it would only limit background processes from accessing the Internet when the phone was in standby. Now, STAMINA limits display brightness, animations, vibration feedback, GPS, and we are warned that background data is also restricted at all times. There is no whitelist. On the topic of background data – you no longer have a choice of apps to be left unscathed by the limiting. Keeping the new STAMINA mode on at all times is no longer a viable option. While it is most certainly allowed in the settings menu, keeping it constantly on will severely hamper your experience. In contrast, the old STAMINA mode was barely noticeable and any Xperia user was used to just have it on at all times. Seems to me I simply agreed with what PA is saying and you're taking offense to it. Sounds like a personal problem to me, no? You can go ahead and try next time, but here take this L with you. :)

It seems to be that you have reading comprehension problem. Read my comment then comment, idiot.

Such a shame really. The OG Stamina Mode works wonders, IMO better than the first iteration of Doze. Now that the settings conflict with each other...it sucks!

Thus is why I love my Note 3 with extended battery. Just use it as is worth no power saving. I do not believe in sealed batteries as the way to go.

Note 3 you say? Kickin it old school. It's time for an upgrade my friend.

Yeah, considering Note7. But I expect it to be with sealed battery. I use my wife's S7 Edge, and the 3600mAh battery is not enough. Old school? I get to put a 10000mAh battery on my Note 3, and not worry about charging for the entire day despite my heavy use. Average SOT runs 11 to 12 hours on a charge. Can't complain. Getting a thin phone and carrying a power bank to top it off during the day is plain silly. Why are we wanting to inherit the problems of iOS users with sealed batteries, and their fashion of carrying charger/power bank?

My 6SP lasts more than a day on a single charge so idk where you're getting your "facts" from lol. All of which using GPS, Bluetooth, Background refresh, etc. Try again next time.

My average use of LTE is almost 3 GB daily. Sometimes I'm going as much as over 10 GB if in downloading 4k content. Bluetooth is connected to 2 devices, over 7 hours Screen On Time. And I have some 30% battery usually left. I got the statistics too from my first 25 cycles:http://flic.kr/p/H1ju9C

Damn man, that's super excessive. I use on average 300 MB a month. Then again, I'm always on wifi. I just switched back ton Android N and I'm excited to see what the updated Doze does for my battery life. I'm just not sure if it's included in this particular build. I'll have to do some Googling and see if I notice a difference.

I'm still on my unlimited data, might as well use its worth. I use it as hotspot for my gaming laptop, listen to to internet music, etc.

I guess you took my comment completely the wrong way. I was talking about you claiming iOS users carrying chargers/power banks with us when it's simply not true (for the most part.) I averaged 5-6 SOT with my Note 3, 6-6.5 on my Note 4. That was with the stock Samsung battery. Imagine had I purchased a ZL case. When I had unlimited data with T-Mobile for $70 a month, I used at least 60GB a month. Netflix, Pandora, YouTube, hotspot, etc. so I don't doubt how much data one can use lol.

Yeah, I would get even 8 hours SOT on stock battery on rare occasions, but it was a hassle to switch to another battery late afternoon as I have my data always on, and I use even more than 150GB in a month. Hey, it's unlimited, and have a 128 GB microSD. Oh, I even clocked more than 15 hours of SOT on a more than 30 hours period. I'm talking about people with the regular iPhones - which are the most than with iP6+. Why do you think Apple had to make that ugly $100 battery jacket? I just don't see sealed battery as the future progressive direction. That thing will degrade in less than 8 months. With new removable and extended batteries, power management will never be an issue. Never having to go to a service center.

And when I do run out of power, I can regain 100% in a minute of changing to my other extended battery. You'd take hours. What do you do with your iP+? How much LTE data do you use? How much SOT do you use on one charge?

Aw man, this is a disappointment. Waiting for the XA to drop and it doesn't have this mode, will be a huge letdown. :(

Android just keeps missing the basics. I want easy sound mode settings and a built in option to set a mode for a specific amount of time or tied to a calendar event. I want a smart battery saving mode like Sony Stamina. And I want the option to have popup notifications stay on screen until I acknowledge them instead of popping up quickly and then going to the notification bar. Most if not all of this can be done by adding apps but on version 6 of an OS it should already be built in.

Luckily I decided not to wait for the Marshmallow Stamina and went back to 5.1.1

If Sony does not bring Stamina back I think that I would stick with my Z3... best phone I ever had and in perfect conditions....

I still have my Sony Xperia z3 t mobile i use and don't use stamina mode, not much difference but want a z5 premium hopefully t mobile gets it, but we will see but will settle for a unlocked version but not sure if the 4g LTE bands from t mobile will work??

Good luck getting Z5 Premium in USA. I had to pay full price for mine from expansys. All the writing on the box and the phone was set to Chinese when I got it. If you go that route it should work on T-mobile but I use ATT.

My love broke up 6 months ago and left me heartbroken, this made me sick and my problem became very very difficult and it made me almost gave up but after the love spell from Robinson Buckler, my relationship was restored instantly, I was happy that the outcome was fantastic, only 3 days after robinson.buckler@yahoo.com started it all. Never in my life have I thought this would work so fast. My man reconcile with me and he started acting completely different, we make love everyday (last weekend, we did it 8 times in total!). Now I can say that Robinson spells work! I can now say I feel happy once again, and like never before. It felt so good to have my lover back again, Thanks to Robinson, contact Robinson buckler or call him +1(971)-512-6745 Patricia Bowen from New york,USA

So you used voodoo to force your man into a relationship he didn't want? You're a bitch... And you had sex with the guy while he was forcible put under the influence of your voodoo.... That's called rape.
