[Q] Stamina Mode

With Stamina Mode on, the battery is decent. My question is,
1) if I have it on 24/7 forever, will it harm the Z3 alot?
2) if I keep using it with screen on like playing games and have the stamina mode on, will battery goes even faster then its not on?
3) what about the ultimate Stamina mode?

I'm also wondering about that. Hope someone will post here some information.

1) No, it won't harm the Z3 at all.
2) Stamina mode, if you set it up for extended usage will limit the performance which you may, or may not notice when playing games. Battery drain will be less than without Stamina mode.
3) What about it? With it on your data connections are gone, Calls and SMS are your only communication mediums available, and a limited selection of basic apps (Calendar, Clcock, Album, FM Radio, Calculator) and the Camera. This of course rules out gaming.

Ultra Stamina Mode is usually for when your battery hits the 10-15% mark and you need extra juice for the next few hours. As mentioned there is no data so only calls and SMS.

So ultra stamina is like in aeroplane mode. No wifi/bluetooth as well?

STAMINA mode effect can be seen only when screen is off.
I will quote sony
When the screen is off, in order to save battery life, WIFI and mobile data will be temporarily disabled, and most applications will be inactive.
When the screen is ON, your phone will function normally.

So that means, when screen is ON, stamina dosent do anything. Your phone will act like there is no stamina mode at all.
Here is information about Queue background data
Another new and important power management feature is the Queue background data* functionality, which minimises the number of network connection attempts when the screen is off. By queuing and releasing all network requests at set intervals of 15 minutes, the time spent in the connected radio state is minimised and the battery life is increased. When Stamina Mode is enabled, the Queue background data will only queue the connections for white listed applications, since all other applications are already blocked from using network connections.

Hope it clear out for you guys a little bit.

I have problems with Stamina Mode. It doesn't work for majority of the apps. Meaning, even if I don't whitelist an app in the stamina mode, their notifications shows up and they send/receive data: Pushbullet, Gmail, Twitter are only few examples.
Is this the case for any of you?

Can you post screenshot of your configuration so i can tell you more.

Based on this, everything should work fine. Only two apps are allowed, and this too check for notification every 15min while screen is off.
I dont know what cause the problem :/.
Also, remember when you put your phone to charger, stamina is disabled while charging.

Yeah and I can't be the only one
First I thought the problem might be due to light flow app but disabled that and tried without that and result is the same.
(Should I have uninstalled, not sure but I just disabled light flow when testing)

Just out of curiosity, is there anyway to auto trigger stamina mode without rooting the phone?

Turn on Stamina Mode, and you can set what percentage of battery it activates at.

Stamina mode on and still receiving notification

Hi everyone,
The Stamina mode seems not to work properly on my Z3. Indeed, although the remaining battery time increases dramatically when I activate it, the Z3 still warns me when an email arrives or anything else. Plus when I switch the screen on I clearly see that Wifi or mobile datas is not paused. I can even ping it when on wifi. So I wonder if the Stamina mode actually works. I have already delete cache and datas of the app in Settings but nothing changed.
What about yours ?

when u turn on the screen stamina mode won't prevent data usage
it almost works when users turn off the screen.
also there s an option to avoid waking up the phone on lock screen (when using stamina mode)
:good:

Thanks for you answer. Yesterday I saw it worked because as soon as I turned the screen on I saw the LTE network back and all my emails
flowed.
What I mean is that I know that mobile data is on when the screen is on, but from what I checked there's always a bit of latency for the cellular datas to be back when you switch the screen on., and usually I see that they are newer switched off except on scarce times like yesterday.

[Q] Z3 Dual D6633 + Lollipop: from heaven to Hell

Sony xperia Z3 Dual D6633 Android 5.0.2 Build 23.1.1.E.0.1
Hi there,
Upgraded my Z3 to lollipop last week and, despite the fact that the upgrade itself was flawless, I think I went from a device that used to work like a charm to one full of annoyances.
On day #1, noticed the batt drain skyrocket. 3h after disconnecting it, it was at 68%, half way through the morning. WTF? was my first thought. On a typical day on kitkat, I was able to end the day at 40% at least.
The second thing I´ve noticed was the phone app. It starts giving me errors, saying that the "network could not be reached" when I try to dial a number. If I insist for 4, 5 more times, it crashes. Dialing is only possible again if I reset the phone.
The third thing is the lock screen. It seems that lollipop has a drop down menu that makes it possible to enable/disable lots of things, like communications and even setting the phone in airplane mode. Imho that´s a huge liability / security risk and it appears that there is no way around that.
Still about the lock screen, it seems to have a bug: if you have any activesync account setup, not notifications will show up, no matter how you configure it (to show all or hide sensitive content).
So, I had only one thing to do, after reading forums etc... factory reseting it.
Surprise! All problems are still there.
Does any1 have any tips on those?
Thanks in advance.

There will be a widget on one of the screens which keeps refreshing itself and I found that to be the battery killer on my 6603.

Did you use any specific app to pinpoint the culprit?

1. It is possible that the battery levels are calibrating and will be imprecise for a while after the update, using the device normally for a couple of days will fix it, or at least this is what I observed in many phones I owned.
2. This is very weird and I can't help you with. If not even factory reset did help you may have some corrupted data on one of your contacts maybe? Try to make a thread about this issue on the Sony forum.
3. I noticed that as well, but even on pervious versions you could turn off the phone so I don't think it changes anything. Make sure to disable the multi user options that would allowanyone to add a new user from the lock screen.
4. Another weird thing, I use exchange accounts on my phone and I don't have any problem on mine. See point 2.

Under
settings>sound and notifications>when device is locked
Set to hide sensitive notification content or don't show notification content at all.
This should fix lock screen displaying email notifications from your exchange account.
Also, unlock phone, pull down notifications, pull down again to reveal quick settings, hit the edit button (pencil) and remove icons but clicking and holding and drawing them to the top. Unfortunately this removes them even when phone is unlocked but of your worried about unauthorised toggling of things on off its the best you can do I think.
As for battery drain, check the battery usage in
Settings>power management
Make sure stamina mode is on, toggle it off then on to make sure.
Select battery usage and check to see if any apps are using more than they should. Make sure brightness is set low but enable adaptive brightness under display settings.

That's not a smartphone anymore, with all functions shut down and brightness low.
This phone has the best screen, use it at least 50% brightness.

I have no issues with the brightness down. It bumps up nicely in brighter conditions and will even max out in daylight. If I ever need it brighter then it's easy to boost temporarily. It's a small price to pay for nearly 24 hours of battery with 5 hours screen on time.
I never mentioned shutting down functions. The only thing I mentioned removing was the toggles that concerned the op on the quick settings. Removing mobile data and aeroplane mode from quick settings hardly cripples the device, I never use these anyway.
I don't think it very useful that there's not more customisation available here such as a complete set of separate lockscreen settings. But if all you can do is comprise then what else can you suggest?
I don't think unlocking the bootloader and installing a custom ROM is something the op wants to do.

You said stamina.
Stamina means already some functions off.

Update:
1. Batt drain
Remains without an explanation. My daily use profile is basically the same as before the update. 3PM and I am at 28%, with stamina on. I can´t recall a day, running kitkat, that I would hit the charger at night with 28% of batt remaining (and I still have 4h to go). It was always on 40% ish. GSAM is reporting that 47% of the batt drain is caused by apps and, from that, 30% is represented by android core apps + android system + kernel. I might be wrong, but I think it is related to reindexing, contact + agenda sync etc and it will probably get lower eventually (I hope!)
2. Phone App giving errors
I think I have isolated the problem. It seems to be caused by TrueCaller.
3. Lock screen
Regarding the drop down menu, It is clear now that what I think is a problem is, in fact, by design and there is no way around it without rooting. But regarding the notifications, I just removed both activesync accounts and I started getting notifications in the lock screen again. So, my guess is that there is a policy of some sort that is being interpreted by the phone as it should hide all notifications from the lock screen.
In fact, there are lots of things that got blocked / disabled because of those policies. Here is a list of things that were disabled and now appear to be working again, after the removal of the activesync accounts:
. notifications are showing again in the lock screen;
. smart lock;
. screen lock options (none, swipe, pattern);
note: I thought that I would be able to enable services in Accessibility, like LastPass or App Advisor by Norton, but it still does not work (I try to enable any of them, but pressing "ok" on the warning dialog does nothing and the only option working is "cancel").
Thinking about resetting it again...

Hi, if problems are persistant you can always downgrad software at KitKat by using FlashTool and wait Lollipop 5.1 (5.1 will probably solve many problems).

A new firmware version has dropped for the Z3 which I think fixes your issues with notifications.
I received it OTA yesterday, I'm running the Balkans customisation.

Thank you for the tip! I hope it does! Will keep it posted here just for the reference. I am starting to feel other "symptoms" as well, like bluetooth instability (you pair a device and it stops working, have to pair again).
.

Just hit another weird thing.
I am not being able to create a new vpn connection. I am trying to use the PureVPN and IPVanish client software, but when I try to setup the conection, I receive a disclaimer, saying that my traffic might be monitored, with a "CANCEL" and "OK" options. The OK doesn´t work, only "CANCEL".
My device is encrypted and I have also noticed that I am not able to decrypt it.
Also, If I go to Accessibility and try to enable a service, the same thing happens: a disclaimer appears, saying that the service might observe my actions, with a "CANCEL" and "OK" options. The OK doesn´t work, only "CANCEL".
Any ideas?

Ok, just a quick fup: the ability to create VPNs from apps is disabled if you encrypt the phone. It seems that if you create if before encrypting, it won´t be disabled; but you wont be able to create a new vpn from an app downloaded, after encryption.
Regarding the Accessibility > Services, after a *lot* of research, I have found that Twilight was the culprit. For the reference:

Restrict all background data when screen is locked

Hi,
I come from sony xperia z3 compact, which had a really cool feature, stamina mode, and what i especially liked about it, is that when it was activated and you locked your phone (screen lock) - it restricted ALL background data, no exceptions. Only when you lighted the screen, it would activate the data. Does anyone know, how can i achieve the same feature with the Samsung S7. Basically all i want is that if i lock my screen, all the background data is truly disabled?

Samsung's equivalent of stamina mode would be the "Power Saving" option, of which there is two tiers("Mid"and "Max"). Background data is restricted by default in both modes, although I think the "Mid" tier still allows it periodically.

Yeah i saw them, thanks for the input, although the MAX setting makes the phone lose its features. I will try the MID setting (i disabled the limiting of cpu and some other stuff, because i want it to function normally when i use it). Maybe theres an app, that will make it work just like i want it. Because the s7 battery should last longer - with sony, wifi off and background data restricted, i sometimes got like 4 days without charging. I am not a 24/7 nose in the screen type of a guy anyways, i mostly call and when neccessary look stuff up on google and read my mails. Would be nice to extend this S7 battery to around 3 days or so with such usage.

You can add *some* apps for use in MAX mode, most notably WhatsApp. Maybe use Tasker to toggle data when the screen turns off?(Would need root though). But yeah, there's only so much you can do for a big AMOLED paired to a power hungry SoC I've never known more than a day and a half's usage though. Perhaps other people have better suggestions.

so far its been 6,5h since last charge, and its on 91% - with the mid power saver mode, cpu limiter disabled, screen res on FHD, screen brightness about 40-45%, wifi off, and gps on high accurancy - it looks somewhat promising. I'll see how long it will last on that charge and proceed from there.

Anyone has battery draining issue?

Bought the XZs for almost one month. The battery performance seems not as good as expected. It seems even worser than my old phone, LG G2. I tried to change a new XZs and the same problem exists.
Phone Idle always take around 20% of the battery use. Stamina mode is one and 2-3% is gone even the phone is not in use. The same issue even happened in safe mode. And fast charge is not fast at all...
Googled some posts and found that some people, XZ users, experienced the same issue. I have tried uninstalled Facebook and Messenger. Seems not help.
Just downloaded betterbatterystat, I hope can find some cues there later. But if anyone can advice why

You installed betterbatterystats? That requires root right? Which isn't available yet I believe... Guess we'll have to wait for root to investigate this

Seems like this is Android 7.1.1 Nougat's problem.. Is it the Android OS percentage is very high in the battery usage list? Many Nexus devices also having this problem.. My XZs can only get nearly 3 and half hrs of SOT omg, seems like the doze is not working well, saw massive of wakelocks during screen off..

Hey guys, after some researches and testings, seems like my XZs is having good battery life now. What I did was go to Chrome > Settings > Site Settings > turn off the Background Sync option. Now my latest full charge gives me 2hrs 43mins SOT with 49% battery left, with 1 hr gaming. Hope this helps, good luck everyone

I've been using Xperia XZs HK version for about 2 weeks.
I use an app call "Brevent" to keep background apps in standby mode when they're not active.
I think there're also some issue with Doze mode on Xperia phones, it drains battery more than I thought......
Then I found an app call "Force Doze" to force it go straight in Doze mode while I shut the screen off.
Now it only cause 1% per hour while I shut the screen off and leave WiFi or LTE on.
Or 1% per six hour while I shut screen off and keep the phone in Airplane Mode(very useful at night).
By the way, both "Brevent" and "Force Doze" does not require ROOT, but they need adb for authorizing their activities.

No, it doesn't.
Brevent only kills process and prevent them from running in background while you have already swiped the app from "recent apps". It does not affect background activities of apps which are currently in "recent apps".
For those apps which requires sync service (for example, "Gmail"), you can set them to "allow sync" in Brevent.
Then these apps would be allow to sync in background periodically, instead of allowing them all the time.

cool, it really helps a lot during screen off! it just took 1 % when i wake up.

I do not have the Problem. All sync enabled, Bluetooth on, really much apps installed. At end of day 37% remaining. Its impressive. 41.2.A.0.219.
