[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:

Power saving mode and data synchronization

Got the marshmallow update. Everything seems good but, for the data syncing limitations on power saving mode.
It doesn't seem to let you choice which apps get data. I'm not rooted, but if rooting will give me control over this aspect I may have to root. What good is a phone that has 2 hours life with syncing and 12 hours but hey people want to email you, or your boss wants to use yammer with you and Samsung said muhahahahaha and nope.
Anyone?

Ok
1) with adguard on and powersaving mode on, there is no Internet, period.
I have sent a bug report to adguard.
2) whatsapp works
3) email does not work unless you open it manually.

Anyone have a adblocker that works with powersaving mode on?

Power saving mode.
I think i can help you.
Go to Setting > Battery > Battery Usage > More > Optimize Battery Usage > "Apps not optimized" option. Choose "All apps" and turn off Apps that you need to sync data in background.
Sorry my bad English.

Thank you, that setting does not have the Google mail listed. I have added both yammer and adblocker to always on. The adblocker still does NOT work.

Thanks for pointing out the settings. The Gmail application is not listed in there. I have added the application yammer to it. The adblocker still does NOT work even with it listed as always on.

Multitasking not working properly

Hello, Android keep killing apps. For example I browse web on Chrome, open Google Maps and after a few second switch back to the Chrome and it's already dead, so it take time till it opens and loads web page. It happening with basically every app including Google Now Luncher.
I haven't got any task manager, developers options are set to default, RAM usage is on 300 MB. Have anyone idea how to fix it?
Phone LG G Flex 2 (H955), Android 6.0.1

have you turned on doze??? or powersaving modes??
are you rooted??

Battery saver is off and in Flex 2 there is no settings for doze, but "Ignore optimization" window where you can select apps individually, but it didn't help.

[Guide] My Battery Optimization Guide for OnePlus 6

Hello everyone,
This guide is for non-rooted, stock-firmware phones. It is geared more towards getting good stand-by times, but of course this will also benefit screen-on time. It has some OnePlus-specific things but also many non-specific to one manufacturer. It does not contain miracle information, but from my experience it can help quite a bit. It assumes that you keep phone, mobile data, Wi-Fi and sync enabled at all times. Those are core features of any phone and are not means to save battery. The optimization steps are listed in the order which I think impacts battery life. You may or may not apply some or all of the things listed, depending on your own needs.
So:
1. Go to Settings->Battery->Battery optimization->[tap on the 3 vertical dots on the upper right corner] and enable the phone's "Advanced Battery Optimization" (aka. Aggressive Doze) feature, while at the same time whitelisting apps from which you need instant notifications, like Whatsapp or Outlook, etc. For other apps notifications may be delayed. Some applications like AdBlock Plus for Samsung browser also need whitelisting to work properly. Just go by trial and error with finding which applications need whitelisting.
2. Enable "Developer Mode" by going to Settings->About Phone and tapping 7 times on the "Build Number". Then go to Settings->Developer Options and enable the "App Wi-Fi Multi/Broadcasting Filter" option. I did not find any app impacted negatively by this, even casting to Chromecast works fine.
3. Go to Settings->Display->Ambient Display and disable the "Lift up display" and "Wake screen on notifications" options (which are useless compared to a true Always-On Display option anyway), and instead put the phone's RGB notification LED to good use. The Light Flow (one of many, but in my opinion the best) app can customize the LED color for different types of notifications, as well as setting a priority or cycling between colors. Since the LED's "always-on" nature, it is actually much more useful than a dead screen that only wakes up when lifted. When I use Light Flow, I set the LED blinking speed to "Always On" and a diffent color for each app. Works much better than any "ambient" mode.
4. Go to Settings->Display->Themes and enable the "Dark Theme". It reduces power consumption for OLED displays such as the one from the OnePlus 6.
5. Social media apps (especially Facebook) are battery hogs because they need to continuously gather your personal data and usage information. If you are only an occasional user, prefer uninstalling those apps and instead using the browser to access your account. This will also benefit you in other areas, like productivity
6. Keep Location off until you need it. This will ensure that the system does not wake up the GPS due to some obscure request from an app that can also work without knowing your location.
7. Go to Settings->Apps->Application list, tap on each app and review permissions. Remove Location permission for apps that you don't want to unknowingly wake up your GPS and draining your battery. I prefer to only allow Location access to Google Maps and Waze but your mileage may vary.
8. Disable Face Unlock. Activating the front camera so often does consume quite a bit of battery, as can be seen in battery stats. And as you may have read, it is not very secure anyway. As the rear-placed fingerprint sensor makes it almost unusable for me (for example I cannot unlock it while in the car cradle or on the desk), I chose to use the Smart Lock features with my Bluetooth smartwatch and my home Wi-Fi network and my phone stays unlocked while my smartwatch is around, which eliminates the necessity for both face unlock and fingerprint reader.
9. Prefer using software from companies that do not live from user data (like Google and Facebook). Collecting as much user information as possible requires wide system access and takes up a lot of battery. I like to replace Gmail with Microsoft Outlook (even for my Gmail addresses) and I use Samsung Internet instead of Chrome. The Samsung browser seems to be the most battery-efficient browser available, way above Firefox. Microsoft Edge may also be a good alternative.
10. Use an ad-blocker if supported by your browser. Animated ads and additional loading of ad-related content contributes quite a bit to the web browsing battery drain.
11. Go to Settings->Accounts->Google and for each Google account, tap on it and then disable syncing for information that you do not need synced. Clicking on a Google account shows you sections of info to be synced. Disable what you don't need. For example, you may only need Contacts syncing for your primary Gooogle account and not all of them. Same with Google Fit data, pictures, etc.
12. Go to Settings->Apps->Special Access->Usage Access and disable this access for OnePlus Switch and Google Play Store (not for Google Play Services, it may have unwanted side effects). This stops these apps from consuming system resources and battery to continuously collect usage data.
13. Go to Settings->Apps->Application list and disable applications that you don't need and can be disabled (some cannot be disabled).
14. Opt out of (do not enable) the "send diagnostic information" checkboxes whenever you are asked for, unless you are really selfless and want to give [a percentage of your battery life] to the community Go from app to app and see if it has this or similar setting (sometimes these settings are sugarcoated into "enhance your experience by sending your data to us"). Disable if found.
15. Do not enter your OnePlus account information. This will activate all kinds of data-sending services that will contribute to the battery drain.
16. Wipe cache after each update, especially if you notice worsened battery drain. To wipe cache, turn off the phone, then hold Power + VolDown buttons continuously until it starts, keep holding until a menu appears. After you enter your phone password you can choose "Wipe Cache/Data" section which brings another menu, choose "Wipe Cache" then after confirmation, choose Reboot.
17. If you are not using the landscape mode a lot, prefer to lock the phone rotation in portrait mode (the toggle is present among the quick toggles) and only unlock the rotation when needed. From what I have read, somehow the auto-rotation seems to unnecessarily cause some activity (even wake-locks), and from my experience I did see a bit of improvement from this tweak, looks like more than placebo.
18. If you already have a OnePlus 6, this does not apply. But if you are after ultimate battery life, keep in mind, less chips means less power draw if all else is equal, and RAM memory needs continuous refresh, so a model with 6GB of RAM may be a bit more power-efficient than one with 8GB RAM, especially given the fact that still-large 6GB of RAM virtually guarantees that there will be no extra overhead related too app reloading.
Hopefully this will help some people.
Below you will find some of my usual stand-by times after the optimization. Since update 5.1.7 battery life seems to be improved even further (see last 2 screenshots - with 5.1.7 and 5.1.8).

Thanks for all this. Most of the things I already did myself, but some of them actually make a lot of sense but I've never thought about it before.
Already very happy with the battery life I'm getting, but very curious if it will be even better now.

Thanks for this nice pice of guide!

All of this means nothing if you have really bad cell reception like me. -105 to -112 dBm at the office. Drains like hell in standby.

Correct !

well done on post [emoji106]

Dumb question, is Advanced Optimization (with some apps not optimized as needed) definitely more efficient than normal, with every app set to optimize as by default (and everything works)?
Why isn't there 3 settings for every app: not optimized, optimized, and advanced optimized?

As you may know, especially if you purchased your phone or accessories from the OnePlus website or accessed the OnePlus forums or support, you can create a OnePlus account online. At phone setup, OnePlus asks you to optionally enter this account for various benefits. Do not enter this information when/if asked. Or, if already entered, you can delete it from Settings->Accounts.

Ok, Thanks bro.

For those suggestions that cut down on network chit-chat, this also serves as a partial data usage optimization guide. Thanks for taking time to enumerate all these suggestions. I found a few slam-dunks in this list.

I was also facing this weird issue, then I noticed that the phone wasn't deep sleeping for some reasons, I rebooted it before going to sleep and it went to deep sleep fine and the drain was around 2% on LTE standby overnight. I will try different kernels too, currently using EX.

Sync (data?) OFF when screen is off

* Often when I work the mobile is at my desk but I still comunicate by sending SMS and using Whatsapp in my webbrowser. Works fine with Samsung and Huawei but with my new Mi10 Ultra id does not work. Connection is lost and I have to tuch some key on the phone to light up the screen and then it syncronizes.
I have set permissions for the apps to allow both autostart and not affected by the battery saver in the system.
I have also set the "data usage" for the apps to allow background data.
...but still, background data for SMS and whatsapp IS deactivated until I light up the screen.
Has anyone run into this problem? Is there any general (mayor) switch for this that I have missed?

This happens to me with Gmail. Sometimes they come in on the lockscreen and sometimes I have to turn the phone on for them to appear. I still have this problem on my Samsung S20 Ultra but I learned to live with it since I never figured out what the problem was. I have no such problems with my SMS or WhatsApp though. Everything else for me seems to be coming through.

Hi there. I pretty much have the same problem with this phone. If it's not permissions nor background data, it's the power saving feature, which is the most aggressive I've seen yet.
I was talking with someone about this in another thread, but I was instructed to turn off battery saver. It got better for a day, but it kind of returned back the way it was. I think you could try and play around with the power saving settings for the apps you want immediate notifications from, which I haven't had time to do. Please let me know how it goes for you and I'll find time to play with it this weekend.
