[Q] Stamina Mode not working

Got my Xperia Z sim free on Friday. Everything was working fine initially but Stamina Mode just doesn't seem to be working properly now. Don't know if it's a software or hardware problem?
When I press the toggle, the standby time left doesn't change at all? And the figure it gives seem permanently low. I've charged it fully overnight and it says standby time left is 8 hours? That said when I have left it in Stamina Mode its told me on a couple of occasions that certain apps are preventing it from working properly (Google Sync etc) but it'd be nice to know if it was working.
Any ideas?

Some problem here... So probably is a bug on the firmware. On the 4.2.2 probably will be fix

Same problem here was fine on first day then went all odd.

Likewise
I'm also seeing this problem. In addition it appears the Google mail client which was getting mails by push due to it being white listed in the stamina application list have also stopped coming through when the screen is in standby. Be good to see what that the situation is.

Same.... Stamina mode takes a while to update the standby from memory. I
white listed gmail and stopped getting mail. Maybe it's just not that clever or as data is off it can't truly be white listed.

Same as of today.
Standby time has no change with toggle on or off.
Showing 14hrs off full charge.
Cleared everything out of stamina mode & reset defaults on all apps but no change.
Don't fancy doing a factory reset yet so I'll lurk here & see if it gets resolved any other way.

Same here.. But im guessing the stamina mode takes the avg time of our usage too, being a new toy we use it alot.. Hence the total time is from our usage... Only my humble opinion thou

My stamina mode seems to be working again. Yesterday it stopped and would show the same figure regardless of whether on or off. Woke up this morning, now on 75% it's showing 15hours on, 8 hours off. But nowhere near the 4 days I was getting on 90% when I first got it.

No issues here with stamina mode. I'm not sure yet if it makes a difference, but at least it's working

Stamina Mode is buggy as hell, done a few tests and with it on my mail doesnt come through even though its white-listed. It only stops notifications coming though, it doesnt turn the data off like it says it does. Hope 4.2 fixes these problems.

My stamina mode seems to be working again, bugy things :highfive:

Same here. I also have Exchange (Hotmail push) that is "preventing stamina mode from saving power"
Does anyone know whats going on here with this notification?
I didnt quite get the idea of Stamina.
Was it supposed to disable data when screen off?
or just prevent apps from using data but keeps the data connection alive?

Something is seriously wrong with this software!
I have already made a reset and a repair of the phone and everytime the result is the same...
In the first couple of days stamina is working right, after the second day (third day at the most), it stops working!
Anyone knows how to fix it?

I've thought I was the only one having this kind of issue... Well the same thing happened to me. The strange fact was, that stamina mode stopped worked after I've rooted the device. I was thinking the r00t made the stamina mode doesn't work. I guess I was wrong... Stamina mode was the coolest feature on this phone - it will be sad if we can't use it

Out of the box my stamina mode was showing 30+ hours on & 20+ off.
2 weeks later it's now showing 18 on & 12 off on a full charge.
F***ing thing!

.
Guys, you should try the Sony Update Service software - it helped me.
I got 20hrs. on average and Stamina mode not working, also that fast discharging with not entering Deep Sleep. All is fixed now when I have just re-flashed the stock ROM. (May be the Stock ROM downloaded through the Sony Update Service is somehow modified and not the same version I had on the phone initially).

how to fix the xperia z stamina mode
1.switch On the stamina mode and low battery mode
2.Connect the charger and charge your Xperia Z
3.Wait until it reach 100%
4.Check the stamina mode .....
It's happen for me.......:good:

Stamina mode - Help Needed

Hi Guys,
I got my XZ on the 1st of march and I absolutely love it, in fact the only thing I preferred about my previous Note 2 was the larger screen, everything else on the XZ is just better.
Anyway.... I'm getting mixed results with stamina mode.
At first, after a full charge I stamina mode would report several days standby time, nut in the last week I only get about 12 hours.
Last night I didnt put the phone on charge, it had 60% battery when I went to bed, I wake up this morning (only 8 hours later) and the battery is on 4%. I checked the battery usage and it said 51% Android system (up till now the screen had been the largest user of battery)
Now I know its probabbly some app preventing stamina mode from putting the phone to sleep, but I cant work out which one.
Is there any way to see specifically which app or part of the android system is using that much power while the phone is on standby?
Are there some options I'm missing which force all apps to sleep?
Does stamina mode automatically turn off wifi and gps when the phone is on standby?
Any advice would be much appreciated.

Stamina Mode not working?
look at my screenshots
the first two days the difference with and without stamina-mode was huge...so from 1day to 3-4 days
sync is off
facebook deaktivated
and lots of other things are deaktivated
only whatsapp is on
what could the problem be?
if stamina mode is on...every thing is deaktivated...there aren't extra apps which still will down/upld data in stamina mode

Akkuschonmodus - I do not have this enabled along with Stamina mode.
Why are you if you are on 92% ?
Should have nothing to do with this problem tho.
Kind regards, Stefan.

i experienced this too
and don think any problem
cause when u use phone and apps they store lots of data that need to process (the exclude apps in stamina)
So time will reduce.
i had 4 days now i have 1day.14hrs BUT after 48hrs it didn't use even 50% of battery. (it was 54% )
anyway if u think u have problem restart ur phone with power button + vol.up (hold down 10 seconds)
and then turn on ur phone.
Or reset factory.

Battery drain issue with new Xperia SP

Hi,
Its been a week since I bought the Xperia SP. The phone came with 50% battery with an estimated standby time of 2 Days. Now, the battery discharge really quickly. With a 100% battery it lasts only for a day (Estimated standby time of 20 Hours). Well I only listen to music on my phone. Brightness is kept at 1/3rd level and mobile data and wifi aren't used at all. I do a little bit of casual gaming. Subway Surfers , to be more precise. That's all. Also when you switch on / off the STAMINA mode, it doesn't effect the battery life. Estimated Standby Time sticks to what it was before switching on the STAMINA mode.
I need help in order to resolve this situation !

Bro
Read before you make threads.already many threads about battery life of xsp
For the stamina mod problem do this
Settings>apps>all apps>eco mode controler/extended standby mode controler.
Clear its data and reboot.
The stamina mod should work fine now..do this whenever you find the stamina mod buggy
Hope i helped u

Man.. don't keep saying this like theres a bug with stamina mode.
It's not a bug, the reason his stamina is giving same estimated standby is because stamina is not making a difference, clearing data won't change this....only hide the problem for another few days.
Instead we should try find why his battery life is not good but from my experience this won't be easy... I think there's a problem with the xperia sp's stock rom causing fast battery drain.
@Gamer R - First thing to do is check battery stats for an obvious case. If there isn't one my best recommendation is to restart the phone. This can reduce the battery drain for a couple of days, sometimes restarting doesn't help though.

Maybe its not making difference for you.but it makes diffrence for me and many other friends(using xsp and other xperias)if stamina mod didnt make a diffrnce why would sony add it?jst an extra app?or as u said earlier for marketting?i dont thnk so...

It might work for you.. but in OPs case it clearly isn't otherwise his estimated standby would be different with stamina enabled.
The phone does calculations related to your usage/battery drain to work out any benefit from stamina, if there is no benefit it won't report better standby time. Clearing data resets these calculations and nothing more...it wont fix any problem so there's no point in resetting them.

Anyways i dont want to fight with you on this...i helped him with the solution which worked for me...estimated time resets when you clear the data.clearing data is a temporary solution.

Okay
I think he wants a real fix though.. maybe you should give a disclaimer saying that its temporary and only fixes the estimate, not the drain

@spix123 & @dipesh1502
Well clearing data of Eco Mode did help in fixing the Established Standby Time. Time to test it whether is it being accurate or not. Right now I have 14% battery left with an established standby time of 16 hours.

Clearing the data cant possibly have any benefit to battery life, I have a similar problem to you and already tried it several times. If it appears to improve battery life then its just the restart which helped (assuming you restarted)
Right now your stamina mode estimate is not accurate, it takes a few days for it to correct the calculation as all data has been cleared.

I've had an estimated standby of 9 days before but chance of that happening is zero
I got this by having over 4 days on battery without using stamina mode then enabling stamina showed 9 days. This was a fluke though.
What is your battery life like? How many days and what usage?

For me Its about 3 days. Some calls. Some angry birds. At start Stamina Mode shows for me 9 days. But stamina mode mod keep data of usage and analyze them. Thats why after some days Stand By time is reduced. Clear data from stamina mode, it will show about 9 days. Don't use (really dont) your device and it can be possibly to make SP working 9 days. WHen I charge my phone in evening with stamina mode on in the morning (after 9, 10 hours) i still have 100%.
And hundert of times. There was a lot of Threads about battery for Xperia SP on this forum, and reeeeeeally lot threads about battery life in Android at all. Just use SEARCH option.

Are you using stock rom? I know the SP can have good battery life on custom roms.
I've searched through all the threads and none of them helped my battery problems at all so I can understand why OP made another thread even if he saw the other ones.

Yes Stock. But today I will change to existenz mod.

Do you have anything disabled? I don't see how you can get that battery life on stock rom. I've factory reset, tried airplane mode etc.. nothing works, battery just keeps draining mysteriously.
100% after unplugged for 9/10 hours is just impossible. Even when my battery decides to drain slowly it will still lose 5% in that amount of time with no usage.

I have just disabled/uninstall pre installed operator apps, and some stock apps. Turn off bravia engine and gloves mode. And - I use 2G Network only - 3g or LTE Network cant hold battery so long. More traffic - more battery drain.
I use my phone at about 3 months and it still hold 100% during night after full load. More. When I wake up my device in the morning it still have percentage of battery which was when my XP went to sleep.
Stamina mode of course ON.

I tried removing most of preinstalled apps but didn't help at all, also I'm using 2g only.
If I charge phone to 100%, enable stamina then go to sleep... in 10 hours I will have lost at least 20% battery similar to what this person describes http://talk.sonymobile.com/t5/Xperi...ometimes/m-p/474409?sl=y&sso_no_log=y#U474409
Do you have c5302, c5303 or c5306? What firmware are you using, 12.0.A.2.254 or older?

We have (had - I run eXistenZ now) same software. Some people have this issue some not. I think this is hardware problem. Some batt can be better than others. Its like with for example CPU for PC. Some same models U can overclock a lot, and some make reboots after few steps.

Ecomode controller not reliable

Good Day! Im xperia z1 user running on Android 4.3. I just wanted to ask why is my eco controller or the stamina mode looks buggy?
if im going to clear the cache, force stop my ecomode controller and restart my phone while my battery is in fullcharge I got 5days but suddenly when my battery down to 60% I got hours left only (9-12hours) then when I clear the cache and restarts my phone it will be back on 1day++ on 60% battery.
Is there any solution for this? BTW even when im in 4.2.2 I got this unreliable stamina mode. also my Xperia P having this issue. Is this normal?

The predictions of software like the Stamina mode are very unreliable after resetting them. The tool has no data to work with and so it uses a fall back value (apparently 5 days). Over time it collects more data of your usage, needed signal strength, ongoing push data transfer, whatever and gets more accurate.
Resetting the software won't increase your battery life, it will just delete all the usage data and the app will have to start from scratch.

I see, thanks for the response. I will just disregard the predictions of stamina mode. I was just too curious and sometimes questioning if stamina mode is real effective on all its features? Also sometimes I've try to turn it off the stamina mode at a certain battery level and then the predicted hours goes up, but when I turn the stamina mode on again the predicted hours goes down. So that was the time I've decide to clear data of ecomode controller to see the difference.

stamina mode useless?

I understand how it works. But since i dont have any apps installed cause its a new phone, will stamina mode have an impact in my battery life? I tested it and no significant differences in screen off. Its the same one hour 1 percent with or without stamina mode.. The only time i get significant battery improvement is when i disabled google play services.

It also works for disabling the mobile data traffic while the screen is off, resulting in less power consumption and less costs.

It's not important do you have apps or not - I'm using it without any exception (rules in stamina mode), only to disable mobile data and wifi when my screen is off and my battery is very happy because stamina MOD.
It'll still upload/download your files or to be precise - it'll finish to up/dl file if you lock screen in the middle of dl/up process and that great.
The thing is, many apps (stock/system apps) are using network to check for updates (email, XDA, tapatalk....) and this MOD prevent that and saves battery life.

new phone or no app are not important
stamina mod at first just try to prevent some feature to work while phone is in standby
after few days stamina learn from How u use ur phone.
then u will get *4 standby time when turn it on.
so let it to learn from u.
(u can find more about stamina mod in Xperia Z forums cause that was first time of it and thr s lots of thread about it.)

If i may ask a question regarding the stamina mode, i use it all the time and i see major improvement for battery, but i'm wondering since i use Greenify as well, is it worth to use them at the same time or do i need only one of them?

Stamina Mod is enough for power-saving
and cause it s official from Xperia it can work properly and better than another 3rd-party apps with ur device.

I agree... mostly - i think using Greenify too will save a little more energy, because it will terminate the app completely and not just it's data/wifi connection.
Or am i totally wrong?

Stamina mode is all u need.. It terminates the apps and data
