So something weird happened to my phone. I charged it to 100% last night and this morning I looked at it was at 17% battery remaining. I looked on power management and noticed gmail sucked about 50% of my battery.

I force stopped it, turned off, recharged then again it went from 100% to 88% really quickly - what gives?

I noticed and I am on 5.0.2 14.5.A.0.242 (D5503 in UK). Did my phone automatically update to 5.0.2 overnight? I had no notifications or icons saying update complete or installed or anything.
[Xperia Z1 Compact General] rjkmadison:
I have not found the data usage monitor in Lollipop. Is it missing or is my phone messed up or what? The option just isn't in settings. I tried searching in settings for 'data' and the results shown in the image below. Any item I select results in "Unfortunately, Settings has stopped."

It's locked bootloader and unrooted and stock .242, factory reset (and "repaired" with PC Companion).

For me it's right there in the first level when I go into settings. See sceeenshot View attachment 3328611

And...it's back now right where I expected it (and you showed). It was NOT there a few minutes ago. I rebooted once with the Power-VolUp (supposedly wipes app cache) and it was still borked. I did another just regular reboot and it's there now. Very odd.

Thanks for looking for me.
[Xperia Z1 Compact General] camaro322hp:
Very odd indeed. Glad you got it sorted out.

How much over night battery drain is in your phone after lollipop. In my case battery was 14% at night and in morning i found my phone dead.
[Xperia Z1 Compact General] raptor3000:
I'm still on KK, but I have I similar issue. Phone battery drops from 11pm to 6am from 88% to 61% and from 40% to 11% in the last two nights I tested.

All notifications, sync and 3G/WiFi were OFF ?

Battery says that "Android system" drains the most off it.

Hoped that this would be better with LP...
[Xperia Z1 Compact General] rjkmadison:
On LP, mine drops about .5% per hour. Some nights, it's as high as 1.2% per hour. I assume that is related to cell network strength issues.
[Xperia Z1 Compact General] aakash43:
I'm sure cell network is not culprit for me, because in kk battery drain was max 4% in worst condition.

Can I create a pre rooted 270 rom with recovery and SU and flash everything but data partition to keep my apps and data as they are now on 242?

Not sent by me.
[Xperia Z1 Compact General] aakash43:
When i switched off stamina mod after. 270 update the result was amazing. Only 1% over night battery drain 40% to 39%.:)

And one more question is my z1c is completely stock and i want to how can i access recovery. Combination of button?
[Xperia Z1 Compact General] raptor3000:
But still no LP for me. Thank you for sharing.
[Xperia Z1 Compact General] eumanoid:
is there an OTA for 270? if so, did anyone from the philippines get it already?
[Xperia Z1 Compact General] paolo-red1:
Yes you can. I created a PRF method zip (I didn't remove userdata.sin), wipe dalvik cache + cache and flash above 242
[Xperia Z1 Compact General] grisu59964:
I did this and my device runs better than with the initial LP release. So far I had no more problems with critical system memory usage.
[Xperia Z1 Compact General] Giargo:
Hello guys,

I updated to Lollipop Friday and I noticed the following worsenings:

- Battery lasts a little bit less, with the same usage I get 10% less than Kitkat.

- I'm really disappointed to see that the camera got worse! There is like a white patina on the pictures, and the macros with flash look overexposed. Overall there is a loss of details.

- Closing all apps with the button takes 2/3 seconds, with Kitkat was much faster.

- When you turn on the screen sometimes the brightness gets on the maximum for a couple of seconds, then turns back normally.

I updated without to perform a factory reset, I will try to reinstall the firmware with Pc Companion and we'll see if something gets better.
[Xperia Z1 Compact General] wyt18:
could you describe the steps you took to keep your user apps and data (if it was different from when you first installed 242? Thanks!
[Xperia Z1 Compact General] mpattman:
When creating the FTF don't include the file "fwinfo.xml"
[Xperia Z1 Compact General] mandashi:
i know, already solved the problem. but thanks anyway.
[Xperia Z1 Compact General] grisu59964:
I downloaded the firmware with XperiFirm and created the ftf with FlashTool.

Then I created a pre-rooted zip with PRFCreator, including the zips for Xposed and XZDualRecovery.

I flashed the zip with XZDualRecovery and deleted the caches in the recovery. That's all.

It was basically the same way like before, but this time, I did not do a full reset.

Note that there are some pre-rooted zips to download here on xda, but I like to create those files myself.
[Xperia Z1 Compact General] aakash43:
Plz anybody tell does z1c has recovery in stock condition. IF yes then how to access it.
[Xperia Z1 Compact General] Laeery:
Give the ROM of few days of usage. Battery is great for me now. Get at least two days out of it, sometimes even more. I still like the camera, especially with third party camera applications (Retrica...A better Camera is still not supported) the quality got better.

But I have the same problem with the screen brightness, it's more like a flash as if I had done a screenshot...
[Xperia Z1 Compact General] DomusX10:
seem that Sony have plan to release another firmware for Z1C , version .283

I don't know if finally this firmware fix the problems that users notice to Sony: camera quality, battery, auto brightness and so on.

No changelog available . On PTCRB appear this version...I hope that is finally 5.0.2 firmware for Z1C...before the 5.1 version, that I hope works better....

The question is: Sony release lollipop firmware late and bug filled. Now have to spent some weeks (or month) to fix it.

I know that is not simple like say it, but "test ROMs (firmware) before release it for almost a day" is really so difficult? :confused:
[Xperia Z1 Compact General] patoberli:
For me work both 5.0 firmwares very well. Only the MMS bug was affecting me, but as I nearly never get one, it doesn't really matter.
[Xperia Z1 Compact General] BlackArtsInc:
Maybe the last update is 5.1. Who knows? Battery is fine. At least it was on 242. Just installed 270 on top. Most of the time I get a full day or more with around 5-6h of screen on and 2h of calls. So I really can't understand why most people complain. Just root,get rid of junk and use App Ops app to regulate whatever you use.

Seems like we are gonna receive every month an update. Who said Sony is late on FW updates.

I guess soon we gonna have a SonyPop instead of lollipop :D
[Xperia Z1 Compact General] Coirpre:
Slow change to WiFi

After updating to .270, whenever my phone connects to a wifi, the little letters above the cell reception indicator (3G, H+, LTE) stay there for a while, although the WiFi symbol already shows the little arrows. It's not a big problem, but I wanted to ask if I am the only one that has this or if it affects you guys too. It is not a modem issue, I flashed the .242 modem, no changes.
[Xperia Z1 Compact General] aakash43:
It is in. 242 but i didn't tried on. 270.
[Xperia Z1 Compact General] skyhirules:
It does happen to me too. Not a big deal, but what I wonder is whether during those few seconds that the data connection seems still active, data are indeed transmitted or not.

Anyway, lets see if that happens in the new .283 firmware when it starts rolling.
[Xperia Z1 Compact General] Meloferz:
Get OTA notification, but can't apply, "Could not verify"... Well... I have to use Sony Bridge ?
[Xperia Z1 Compact General] camaro322hp:
Anyone know why photos taken with Lollipop would be a bigger file size than images taken with KitKat, even with the same resolution? All photos taken in Superior Auto, and have a resolution of 3840x2160. KitKat photos average about 2MB, and Lollipop photos average around 4MB.

Screenshot showing the details attached.
[Xperia Z1 Compact General] eumanoid:
anyone had an issue with screen flickering when you open the camera after .270? i had this issue right after i isntalled .270 with OTA. it fixed itself though. my camera reset itself and foxed the flickering.
[Xperia Z1 Compact General] patoberli:
Probably less jpeg compression applied.
[Xperia Z1 Compact General] balanced_emotions:
Jpeg file size also depends on the scene captured. The more details and colors result in larger file sizes. So unless you capture same scene, the comparison will not be proper. Larger file sizes may be a result of the camera impovement.
[Xperia Z1 Compact General] kevjs1982:
.270 finally arrived to EE (yet again they've skipped the first release of a major upgrade and gone for the second one).

The three issues I've found are:-

1. FM Radio Doesn't work - silence only, but if you screen record you get audio for a split second as it starts / finishes.

2. Battery drain was horrific, uninstalled updated to the Kindle App then disabled and it's back to mearly being poor (i.e. gets to the end of the day with a 30 minute boost around dinner time) - used to be better until EE changed it so that it prioritised the weak 4G signal over the (3G) Signal Box behind me at work. What's really telling is that the battery drain returns to normal levels at home (4G being the only network available inside, 2G/Edge and 3G need to be outside).

3. The camera takes much longer to launch from the lock screen, but the file sizes are a lot more dynamic - used to be constantly 2MB, now varies between 0.5 and 5MB depending on how much info is in the video. When zoomed in they do look better.
[Xperia Z1 Compact General] jufofu:
Will I lose my root if I upgrade to .270 via OTA? What about using Flashtool without wiping?

I've got locked bootloader.

Okay, I've flashed a zip without wiping and everything is fine.
[Xperia Z1 Compact General] Giargo:
My battery life with Lollipop is really poor, either before and after a repair with PC Companion.

Today at 15.30 I was with 20% with 2.40h of screen.

With Kitkat with the same usage I was about 50%.
[Xperia Z1 Compact General] paolo-red1:
Me too and Chrome is really consuming energy.
[Xperia Z1 Compact General] Giargo:
You italian? Me too :good:

Yes I confirm that, since my usage was only Chrome and WhatsApp.

I thought that the Socialife News app by Sony was eating battery and I stopped to use it, but nothing changed.
[Xperia Z1 Compact General] aakash43:
Try switching off stamina mode it really helped me.
[Xperia Z1 Compact General] Giargo:
It's already off to me, but I'm agree with you that uses more battery and should do the opposite.
[Xperia Z1 Compact General] aakash43:
After lollipop clear audio+ is not working for me, does any one having the same problem.

And plz anyone tell does our phone has recovery in stock condition, i tried every combination but no luck.
[Xperia Z1 Compact General] BlackArtsInc:
Rooting and using app ops application to remove the ability of Google Framework and Google Play Services to keep the phone awake will make a huge difference in your battery life on Lollipop!

Not sent by me.
[Xperia Z1 Compact General] patoberli:
Works fine on mine, but I had to enable it again. I simply updated, without any wipe.
[Xperia Z1 Compact General] kevjs1982:
I've never used it as it defeats the point of a smart phone and seams to make the battery drain faster in any case, the only time I've found it worthy is on the odd occasion when you don't need/want to use the phone for a fair few hours where it can save lot - but as a use my phone as a camera bigger gains can be found by simply disabling Mobile Data for a few hours.

Removing the Kindle App has made a huge difference though, not been warm since, and got through a whole day without issue (Low Battery mode is however still turned on).
[Xperia Z1 Compact General] Giargo:
The battery consumption in standby it's insane, nearly 5% in 30 minutes without to use it (in my office with stable signal).
[Xperia Z1 Compact General] aakash43:
So android M is now in news, is there any chance of z1 compact getting it.
[Xperia Z1 Compact General] poolmaker:
At this moment even bosses from Sony probably dont have firm decision about that :)

Lets wait 5.1.1, it is vaste of time think about M, too early for that.
[Xperia Z1 Compact General] darkshoot:
Hey guys !

I've recieved my Z1C last saturday, it was running on Kitkat.

A bit later, still on the same day I've updated it to 5.0.2, and my battery seems to go crazy...

Do you have some advices to improve the battery consumption or a nice way to monitor how applications drain the battery ?

I saw some of you had this problem and it disappeared after few days, but it doesn't seem to improve in my case :(

Btw, at the moment I'm at 22% with stamina on and 2h30 screen on. I played some Real Racing 3 and GT Racing 2 for like 1 hour, went on the internet for like 10 minutes, no music, no youtube, .... I feel like my old cheap Acer could last a lot longer, even after playing a "big" game one hour !

Do you also now if 4G drains battery has hell compared to 3G?
[Xperia Z1 Compact General] paolo-red1:
So apparently is chrome that is draining battery.

https://code.google.com/p/android/issues/detail?id=165558

Cyanogenmod have/had? open commits to try to fix this. Let's hope it will be a fix with chrome app, because if it's a framework commit like in Cyanogenmod review, we will wait a lot..
[Xperia Z1 Compact General] Kael710:
After OTA to lollipop (completely stock, without root) I encountered disortion when making calls. Its that type of cracking, lagging, hissing you get when you are in badly covered area... But i get full bars, even on 3G and on KK it was just fine.
[Xperia Z1 Compact General] BlackArtsInc:
Well, I'm gonna say it again and again. Lollipop needs root and some tweaks but its battery life can be awesome!

I have uninstalled 'Android System Webview' and now my battery drain is normal again. 80% battery left with 2 hours screen on, with no chrome drain.

Edit: I uninstalled it and now it is like in factory condition
[Xperia Z1 Compact General] Giargo:
Thanks Paolo, really useful!

Lollipop is a great improvement for the UI, the new lockscreen is awesome, the app drawer is better, I definitely prefer the bigger icons, and the smart lock is something really useful.

There are just a couple of things that I don't like, the task manager takes a couple of seconds to close all the apps, and the settings with this colored bar look childish, but it's fine.

Just the biggest skills of this phone, such as battery and camera, dramatically dropped down. I'm seriously thinking to go back to KitKat.
[Xperia Z1 Compact General] Darkimmortal:
I am on .242 at the moment, can I install the .270 OTA and keep root or do I have to go through the PRFCreator process?
[Xperia Z1 Compact General] paolo-red1:
Prf. You can flash over 242, wipe only dalvik cache and cache. Backup first for safety
[Xperia Z1 Compact General] Giargo:
Question for those who purchased this device with 4.3: which version/firmware you think has been the best for performance/camera/battery backup?

I purchased already with 4.4.4, IMHO build .108 was the best for battery backup, .157 for camera/performance.
[Xperia Z1 Compact General] kevjs1982:
I've got all my syncs turned on and with 1 bar of 4g (no 3g/2g signal visible) it's currently at 99% some two hours after taking it off charge....
[Xperia Z1 Compact General] eumanoid:
I agree with you. after installing need for speed most wanted (2gb+), bard's tale (3gb+), dungeon hunter 5(1.4gb) and nova 3(~2gb), I found myself scavenging for space. also, the images i took(~3000+) stored in my sd card generates ~500mb of thumbnails in internal memory. we definitely need more than 16gb internal.

Z2 got lollipop too and I'm just sitting here watching my friends flash FTFs :D
[Xperia Z1 Compact General] ocan41:
z3 and z3 compact yesterday,z2 today got it lolipop

maybe z1 and z1 compact can got it tomorrow ?:)
[Xperia Z1 Compact General] profyler:
Unlikely IMO. Sony said they will release for z3/z2, and only after that for z1. there is a "pause" between z3/z2 and z1... i still think its gonna come in april.
[Xperia Z1 Compact General] d3s4nn:
YES! this would be absolutely awesome!
[Xperia Z1 Compact General] templeka:
Use Foldermount or similar app, get a big sd card and problem solved [emoji2]
[Xperia Z1 Compact General] profyler:
just a info for you guys, i took a look in xperia z3 thread and aparently no bug reported buy users. Anyway, since its sony I always make a hard reset after upgrading to a major android version and i still recomend it when its out for us.
[Xperia Z1 Compact General] eumanoid:
not really, internal sd speed is way better than micro sd. I have a 64gb uhs-1 sd card and it's still way slower than internal sd. That means using a micro sd for large apps will make loading times longer.
[Xperia Z1 Compact General] templeka:
For storing games I would say it's fast enough. Haven't seen any performance impact because I have them on external SD.

"Sony started rolling out the Android 5.0 Lollipop upgrade for the Xperia Z3 and the Xperia Z3 Compact on March 16. Owners in the Nordics and Baltics regions will be the first to see the update, with other markets getting it soon after.

Sony also announced that the rest of the Xperia Z series will get the update in around two weeks, so keep an eye out to see if your device has an update waiting."

There are no major bugs in lollipop on Z2 and Z3. My guess is they will release lollipop for Z1,Z1c and Z ultra(Snapdragon 800 devices) next week as they said in the blog post.
[Xperia Z1 Compact General] eumanoid:
Hi. A few questions for you guys.

1. Do you recommend a full system wipe when upgrading to lollipop? I really like my current settings/customizations/apps aotm and it's really cumbersome to have to dowload all of these again.

2. As i understand, backups from kitkat wont work with lollipop in the same way jellybean backups didn't work with kitkat. Is the risk of having buggy lollipop really high without wipe?

3. How do i retain app data without using titanium backup if i wipe my phone? Some of my game progress are saved locally on my internal memory And the game does not support cloud sync.
[Xperia Z1 Compact General] fightingirish173:
Last week at the Sony booth at the CeBit 2015 in Hanover, Germany, they said, that Lollipop would be released for the Sony Xperia Z1 and the Z1 Compact at the end of March.

But IMHO I am expecting the roll-out for these devices in the second week of April after the Easter holidays.
[Xperia Z1 Compact General] giober98:
We all know that when sony says "by the end of March " what it really means is "yeah maybe in a month or two "

With all the "Stamina Mode is worse on battery" comments, I thought I would report that it seems to work very well for me. I was out of town (Indianapolis) only on LTE (no Wifi) and easily got 2 days of battery using Stamina Mode. This was on .242.
[Xperia Z1 Compact General] uchihakurtz:
I don't think it's Sony's fault about the horrible battery drain. It the mutha-effing Google Service, stand by became really bad. I had to disable it and things break down without. This really made me wanna support CM and Microsoft to free Android from Google. :eek:
[Xperia Z1 Compact General] zlata:
That is why i stayed on .157.Rooted with xposed,paid greenify,appops and trickster mod.I got 42% screen time and 2 days battery!
[Xperia Z1 Compact General] Giargo:
For those who are still on Kitkat, that's my suggestion: don't update!

Lollipop ruined this phone, there are some good features such as screen recording, smart lock and improved lock screen but it's not worth to lose great battery life andand good camera!
[Xperia Z1 Compact General] KSzasza:
Does anybody have the same bug for Lollipop .270?:

After a clean install (restore factory defults) my Z1C works just fine, however after couple of hrs later it can recive incoming phonecalls but without ringtone (only vibrate). No matter what I do later (volume up and down, mute on/off, exchange ringtone etc.) it wont change. The only solution is the reboot, but it will be goond only for max half a day.
[Xperia Z1 Compact General] maninder singh bali:
The camera is gud in daylight bt horrible in lowlights settings are to be done to get perfect shot(. 270 update) and by putting the 4k mod its awesome. The camera results in daylight are better than the kitkat.

My ratting of camera quality according to the android versions :-

First 4.3 (.114) over all gud bt best for night photography

Second 5.0.2 (.242/.270) daylight results are sharper and less pixelated.

Third 4.4.2 (.757/.768) mix bag results

Fourth 4.4.4 (.108/.157) worst camera experience

The best quality of all is from CM 11. CM uses the camera fully...

I hope this will help to decide which is gud or bad only for photography people..

The battery drain is little faster than 4.3 bt not so bad. Over all gud update....

Is there any way to fully disable sound enhancements?

I don't mean the sound limiter pop-up, I mean the fact that at higher volumes the sound seems to be lowered in every beat and hihat, and it gets annoying. Specially because I've already let V4A handle the volume limiting for me, Xperia's limits are redudant and mess up the entire soundstage.

I checked today my battery usage with very low usage. Taken from power at 7.00 am, Mobile was nearly always connected to a WIFI. Around 5 minutes of calls, 10 minutes of games, and around 5 whatsapp messages, updating around 4 apps and surfing a few minutes in the internet. Now at 8.30pm (after 13h30), the battery is at 64%.

I'm fine with this usage rate.
