Let's see, i also got the update yesterday, and first impression was suddenly instagram on top of battery meter, screen second... But i'll know better tonight after night shift at work where i have to use mobile data and chrome.

Edit: Seems that battery drain is still there just the same, but the heating issue and camera has improved.
[Xperia Z4/Z3+ General] pEksi91:
Im happy with the battery life. Always connected to mobile data, when not, then wifi. web surfing, youtube videos, ~30min gaming, whatsapp, tapatalk, ~45min spotify... Yeah, and very first charge.
[Xperia Z4/Z3+ General] Masssy:
Interesting, I'm getting approximately the same battery time but have like 1-2 hours screen on. Yours honestly seem to be too good to be true.
[Xperia Z4/Z3+ General] pEksi91:
Lol, now im sitting with 2h SoT and 65% battery left.And 1day standby.

Just to check the screen backlight power consumption, I left the screen on with a full white image for 20 minutes (50% manual brightness, airplane mode, wifi off, smart backlight control off, timeout 20 minutes). Battery barely dropped from 100% to 99%. Thanks for ruining the party, Google!
[Xperia Z4/Z3+ General] Masssy:
While that might be true leaving the screen on without doing anything with the device keeps the clocks running low. It will only clock the CPU up when you touch the display or tap buttons or has work to do so it's not entirely representable to what people usually call "screen on time". Usually when you have the screen on you do something more like render a game, play a movie, do web browser calculations or whatever.
[Xperia Z4/Z3+ General] schecter7:
That was the whole point - screen backlight is very efficient. Everything else consumes a lot more power. But you read everyday those cool stories saying LCD backlight burns huge amount of power.
[Xperia Z4/Z3+ General] angvil:
I agree 100%
[Xperia Z4/Z3+ General] jamminen:
Oh man

That can't be! How do you do that? I'm from Finland too, it can't be that i'm doing something so different, where's your chrome on battery consumption? It's usually top of the list on my phone... What's going on?? You cheat! :D
[Xperia Z4/Z3+ General] supermies123:
Remember that bad gsm signal eats a huge amount of battery. So if the signal is great, full bars, it consumes much less battery.
[Xperia Z4/Z3+ General] jamminen:
Yeah, but it doesn't explain why chrome eats battery almost 3 times as much as display. I just did a test, watched first almost an hour youtube, then 1,5h movie on 50% brightness. Started at 94% battery, now after 2,5h screen on time i have 64% battery left. That is really great, i had wifi on all the time. Got a couple of facebook notifications during watching, so net connection was working. This is the case when the LOLlipop mobile radio on bug is not affecting. I could have 6 hrs SoT watching movies. But on a normal use i get barely over 2 hrs. Using chrome for web surfing on lunch break at work uses 10% battery in 20+ minutes. That is just insane. I just used like 12-13% on a 1,5hr movie!

But what is odd, is that 44% of the battery was now during the test used by screen, BUT another 44% by cellular standby or whatever it is in english. It hasn't been that high up before, maybe because other things have used even more.
[Xperia Z4/Z3+ General] lilloscar:
I Still 8 hours from full charge to zero... nice

Tried first, rooting, using greenefy, freezing unnecesary apps, etc., second I try to use it the less I can and stills so hot this thing and watching how battery percentage goes down every time I look at it.

Do you think that Z5, if is true that it has the same type hot hardware, will accelerate a solution for us?
[Xperia Z4/Z3+ General] jpl8910:
hi

please someone help me I'm going crazy my battery is drained, Androi operating system consumes 25% of my battery and inactive device consumes 14% i do not know what to do can someone please guide me.

thank you
[Xperia Z4/Z3+ General] jamminen:
Sorry but there is not much to do. Android 6.0 is said to fix this or at least make it better, you could try resetting to factory settings, and/or pc companion repair, that has helped some a bit. My culprit isn't the system but chrome, or any app that uses mobile data.
[Xperia Z4/Z3+ General] juliani:
I had major problems with battery drain. After I got zROM+ with root and xposed framework, and more important, MobileActiveRadioFix module installed my z3+ works like it should.

Now I have 5h SOT, always connected to wifi(when available) and at least 24h before it needs to be recharged. Big difference from the 2,5H with SOT and 12-16H I got before I installed the xposed module.

Bluetooth is also always enabled, because I have a smart watch connected, without any battery drain.

[Xperia Z4/Z3+ General] djurkash:
Sorry, don't get you so clearly...You are running doze and greenify?

Where is aggressive setting located, as I only can turn on or off battery optimization on apps?
[Xperia Z4/Z3+ General] LMcR92:
Aggressive doze is within greenify settings

[Xperia Z4/Z3+ General] br0adband:
Picked up a Z3+/Z4 yesterday for a great price (free, basically) and I have to say that I am rather disappointed in the battery life, albeit I did do one reset from the previous owner yesterday after taking possession of it. I didn't get the QuickCharge charger with it so I'm relying on my LG 1.8A charger and it really does charge pretty damned slow compared to other devices. I was thinking about getting the QuickCharge charger but I may end up selling this Z3+, I just can't get used to the side mounted button placement and I keep accidentally hitting the dedicated camera button, ugh. Too used to LG devices with rear mounted buttons which I think is superior but that's my personal opinion.

As for the battery life so far, I just took it off the charger not an hour and fifteen minutes ago from full 100% charge. I went outside to snap some pictures, test some Wi-Fi (not all that great), test some LTE speeds (definitely weak, I mean really weak considering I live about 1200 feet from a cell site for T-Mobile that I use and it's line-of-sight to me, nothing in the way to impede the signal so it should be much much faster than the piddly 10-12Mbps I was getting.

Right now it's showing it's been off the charger for 1 hour and 29 minutes, the battery is now at 62% (!?!?!) and it has 1 hour and 13 minutes of SOT which I assume is about average, maybe 3-4 hours of SOT in general. It does run a bit warm, even hot at times just above the NFC logo on the back also but that's not a concern. I know the Snapdragon 810 is a problematic CPU with heat and power issues so I guess this is "perfectly normal" for this device. And yes, since it's very sunny today in downtown Las Vegas and I do have the auto backlight thing enabled that could be an issue as well since it was pretty much at max brightness in the sunlight for that period of time I was out doing stuff.

Funny thing is this Z3+/Z4 was manufactured like 10 weeks ago, last week of January (production date is 16W04 so I still think the battery life is atrocious at this point. I suppose I need to give it a few days to settle in and then see what it can do. And yes, it's running the latest update, the 185 build.

LTE is horrible on this thing with T-Mobile on band 4 here, I don't know why: I had an LG Stylo a few months ago and standing in the same place on my balcony looking at that T-Mobile cell site on top of one of the casino hotels barely 1200 feet away from me I was getting speeds in excess of 85Mbps which is what I should expect from this Xperia device.

Apparently either something is up with this particular one I have or they're just not good devices. :)
[Xperia Z4/Z3+ General] diemadedrei:
LTE speed is mostly limited by many users using the same access point, than by actual capabilities of end devices. Greatly dependent on time of the day. At night and in less populated areas I get speeds way above 50 MBit/s so it's definitely not the phone in general.
[Xperia Z4/Z3+ General] br0adband:
Normally I would agree with you but I went out earlier on my balcony to do more testing of this Z3+/Z4 right next to my Motorola Droid MAXX, both using my T-Mobile service with the same nanoSIM (swapped between them) and both basically connecting to the same tower(s) here in downtown Las Vegas. Fully rebooted each phone, waited 5 minutes after the reboot to allow it to settle, then ran 5 speedtests in a row using the Speedtest.net app and then averaged the results - I also had both phones set to LTE Only, just for the record:

The Droid MAXX had a low speed of 76 Mbps and a high of 87 Mbps and an average of 82.2 Mbps from the 5 runs.

The Z3+/Z4 had a low speed of 2.1 Mbps and a high of 14.2 Mbps and an average of 8.48 Mbps from the 5 runs.

So yeah, there's something fishy going on with this device, not sure what it might be - for other people having low speeds with LTE might be the average daily thing for them and they're fine with it, but when my 3 year old Droid MAXX can do this kind of speed with T-Mobile and a ~3 month old flagship can't in the same spot with the same nanoSIM and the same towers, there's just something not quite right about the situation. ;)

I'll continue mucking around with it, the battery life hasn't improved today. I went out and snapped some pics for ~30 minutes earlier and lost 35% of the battery (from full charge 100%) in 27 minutes with the screen on - and I had it in Airplane Mode this time so the radios were off and couldn't be an additional drain.

Not looking too good so far. Takes nice pics, sure - that's another thing for another thread but I don't see why this has a 20.7 Megapixel sensor in it but the images with the stock Sony camera top out at 8 Megapixels... what the hell is up there? - and I'll continue testing but so far this is some of the worst battery life I've ever encountered.

Hell, I still have an original Samsung Galaxy S Captivate (the AT&T model) and I still use the original battery and that phone gets better battery life and SOT than this practically new device does, go figure - and the Captivate is just over 5 years old. :confused:

"Strange things are afoot at the Circle-K..." :p

EDIT:

DOH!!! Didn't realize you had to shift to Manual mode with the camera and then change it to the higher megapixel resolutions on the camera, interesting. Now I'll have to go back out tomorrow and take all those pics I took today again so I can do comparisons. :D
[Xperia Z4/Z3+ General] djurkash:
There's something wrong with your device definitely. I am using mine with LTE networks, with much higher speeds, and only one bar out of 4.

Regarding battery, camera is slightly higher consumer of battery, so that might be the case. Other than that I get regularly 5h of SOT within a day (one day I had 7h), but I am not taking too much photos...mostly browsing, tapatalk etc, but I have bt watch all the time connected, and a 3 gmail accounts to sync. And, mine is e6533 dual sim version.

MM: Google Doze, Stamina mode and wifi toggler apps

Hi,

Having recently updated to MM (33_32.1.A.1.185) I'm looking at ways to maximize my battery life. There are plenty of posts earlier on discussing Data and wifi usage in Lollipop and (in other threads) discussions of Stamina mode's possible return in later versions of MM (although Google Doze is reported to be doing about the same thing.

Way back I remember using an app called JuiceDefender, that toggled wifi and mobile data on and off depending on location.

Can anyone comment on:

Any built-in functionality that does something similar to Juice defender:

ie: When in range of a known wifi network, toggle on wifi and turn off mobile data - possibly even turning down the radio to GSM mode if possible

When outside range of a known wifi network, turn off wifi and turn on mobile data.

Is there any reason why NOT to run JuiceDefender in MM?

What did Stamina mode do that Google Doze does not?

BR.
[Xperia Z4/Z3+ General] djurkash:
I'll compare my experiences...

I've received my device with LP and upgraded to MM (185 build) immediately. Been using it on MM almost a month, and I wasn't satisfied with doze at all. Why, well, there are some objective and subjective points there...In one word, it wasn't doing what it was supposed to do. I had a lot of wake-ups during the night, when the device should have been sleeping, both on mobile data and Wi-Fi. Ok, my Wi-Fi router is one of incompatible ones (for what ever reason, I tried with changing channels, values for dtim, beacon, but it still causes wake-ups of my phone). The biggest "drainers" in my usage scenario are following processes; Android OS, Google Play Services and sometimes Chrome. Combined on MM, I am getting in one day around 4.5-5h of SOT, with 2h of additional awaken state from above listed processes. This is the time, if managed well, will allow additional 1h of SOT. Doze is not affecting these processes except for Chrome). I downgraded to LP in order to test Stamina vs. Doze, and so far I had one day with worse and today with better Stamina behavior:

(Although it is showing Wi-Fi on all day, in fact it was mixed usage).

What you would like to accomplish, I plan to do using tasker, but it requires root. Downgrading was first step, now I need to backup TA partition with DRM keys, and then unlock boatloader, flash recovery and later root. With Tasker I'll be able to automate Wi-Fi, mobile data, auto sync on/off schedules. As this is achieving to my experience will cut wake-ups and prolong SOT...

I was interested in how long the battery can make it, it was amazing to see what is possible didnt expect a SoT of 8,5 Hours.
[Xperia Z4/Z3+ General] djurkash:
it is possible only if you've taken phone off the charger and held it with screen on (video or wifi browsing) next 8.5h, otherwise no way...

e6533
[Xperia Z4/Z3+ General] :
lol, sure it is possible with normal usage. Just underclock your cpu all cores to 1,2 Ghz and dissable the Sony Picture improvements. The only thing i didnt use in this time was Navigation which needs a lot of battery power. And i didnt use Stamina, with this i would make it to much more. If i would just do it like you said, i am sure it would be over 18 Hours of SoT.
[Xperia Z4/Z3+ General] djurkash:
Ok, what FW are you using, can you attach rest of graphs, for the beginning, one with quality of mobile network, awake, screen on, charging etc..lines?

Do you use BBS, can you attach log from it as well?

I know SD810 uses more power, both on idle, and especially when on 1.5Ghz, than it should beusing, but you result appears really unbelievable...

e6533
[Xperia Z4/Z3+ General] :
I´m on latest 224 firmware with AndroKernel v31 and i dont use BBS or something else. What i have done two days ago what could make a big difference is uninstalling most of the Sony Apps, my whole device is much faster now xD even the boot time reduced from about 2 minutes to now 40 seconds after uninstalling all that **** (was about 100 Apps). But i´m sorry i cant provide more screenshoots of that statistics, i use a QC2.0 Charger and it was full 5 minutes ago so all stats are reset now.
[Xperia Z4/Z3+ General] djurkash:
Ok, can you give us a link to Androkernel thread, also, can you attach full graphs next time once you're again close to discharge battery?

Sony UCh 10 Quickcharger

Hello, tried somebody this quickcharger on xperia z3+ ? If yes, how long it takes a charge to full ?

Around 2 Hours from 0 to 100%

SOT

Hello, I'm getting approx 3hr SOT per 50%

Generally 5.5hr per full charge for Facebook, messenger, wifi, chrome, auto brightness.

I've read all the comments and i guess that's pretty average to this phone.

I used to have an xperia Z2, it could have 10 SOT easily with no problems, this feels like a downgrade tbh.

Is there any way to extend battery life? Other than stamina mode, like turning off cpu cores or setting less max frequency "tried setting less frequency for big and small cores, no help"

I have it rooted, unlocked bootloader, custom kernel, twrp, so pretty much able to tweak anything.

Running on latest 5.11 MM build

Thanks!

I recently updated to the developers preview of Fire OS 5.0 and I had TWRP installed and I was not able to downgrade using the ADB sideload method. So for people that have the same issue here is what you need to do to resolve this and get back to Fire OS 4.0

Summary:

Rolling back to Fire OS 4 is easy! Simply visit the page below and follow the instructions provided to complete the rollback form.

http://www.amazon.com/gp/html-forms-controller/wdp_gen_rb

Note: The rollback process requires you to provide both your email used to participate in the Developer Preview, as well as your device's DSN. Instructions on obtaining your DSN are included in the link provided.
[Fire HD 6 and 7 General] DoLooper:
What version of OS 4 does this roll you back to?
[Fire HD 6 and 7 General] siegesoldier:
You had TWRP with OS 5.0. So you had root and OS 5.0? how?
[Fire HD 6 and 7 General] junglistknot:
No I had root on 4.5.4 with twrp and I did not have my nav bar so I decided to try to upgrade to 5.2.0 thinking I would be able to downgrade. I was stuck at this OS because I can't get into the stock recovery or twrp. So basically I need to go back to 4.5.3 to gain root and upgrade back to 4.5.4.
[Fire HD 6 and 7 General] junglistknot:
Not sure yet because it takes like 48 hours to get the update sent to the device. As soon as I know I will let you know.
[Fire HD 6 and 7 General] JUSTINMARMER:
Lol, so just to be clear, this isn't something you've even actually done yet. Nice. So what, you're just working on theory and leading people to do it with you blindly? Awesome. Post back when you have something with substance for us.
[Fire HD 6 and 7 General] DoLooper:
I'm guessing it will be 4.5.4, but if it's lower that would make getting 4.5.3 (and root!) much easier. Hope you can keep an eye on it and block OTA as soon as it comes through. thx.
[Fire HD 6 and 7 General] junglistknot:
This is directly from Amazon and the zip is signed. There is no reason it shouldn't work. I am just trying to let anyone in the same boat as me this may help them. No need to be rude.
[Fire HD 6 and 7 General] DoLooper:
I apologize if that sounded rude. Wasn't my intent at all. I assumed downgrade would be OTA, and it would help everyone if we can get the developer preview and then downgrade in the way you suggest to 4.5.3 or less.
[Fire HD 6 and 7 General] junglistknot:
No not you I was referring to the post above yours
[Fire HD 6 and 7 General] wyldeice:
Have you gotten the rollback yet? If so has it fixed your ability to get to the recovery?
[Fire HD 6 and 7 General] junglistknot:
I finally received the update but I can install it because it still needs to boot to the recovery. Sorry for the misleading post. Just so everyone knows it also was 4.5.4 OTA. So I still need to flash the recovery.img through fastboot so if anyone has this img please share.
[Fire HD 6 and 7 General] bibikalka:
I have 4.5.3 recovery img somewhere, but I am not sure it'd help you since I doubt you could flash anything through the fastboot. I'll dig it up, and upload.
[Fire HD 6 and 7 General] junglistknot:
Yes I can flash in fastboot but it needs to be an img file. I have done it before. If you could please upload it I will give it a shot. Thanks
[Fire HD 6 and 7 General] wyldeice:
In the same boat anxiously awaiting for someone to find a stock recovery.img
[Fire HD 6 and 7 General] bibikalka:
Well, this is 4.5.3. I dd'ed from my recovery when doing backups. See if it works!
[Fire HD 6 and 7 General] junglistknot:
so after messing with this so much bootloader is locked again and I am not able to flash recovery via fastboot. Looks like I will need to wait until someone can root 5.2.0 OS. Unless anyone else has any ideas because I feel like I have tried everything.
[Fire HD 6 and 7 General] bibikalka:
5.2.0 can be rooted, but you'll have to start with a working TWRP, which means you already must have root. For independent 5.2.0 root, you may wait for a long time.

With fried recovery and no root, I don't think you are going anywhere, other than to Amazon customer service ;)
[Fire HD 6 and 7 General] junglistknot:
Well I had TWRP and root beforehand. In fact SuperSU is still in the app drawer but it says the binary isn't installed. I can wait though I know I can bring this thing back to life at some point. I have a galaxy s5 rooted with CM12 on it so that will keep me busy while I wait.

Edit: Amazon is sending me a new Fire HD 7. Be here on Friday :)
[Fire HD 6 and 7 General] wyldeice:
Just curious what you told them? I am in the exact same place as you, but it was with my wife's brand new tablet from prime day. :eek:
[Fire HD 6 and 7 General] junglistknot:
I told them that I tried the developers preview and then requested the downgrade which was sent to the kindle but while it tries to install it just boots normally again and keeps doing this. They had me try to factory reset it a few times but with the same result. Then they said they are sending me a new one.
