How exactly did it worsen things? ... or is it just the usual "it felt worse" placebo judging that people on XDA have? (Im not being an a-hole towards you, I just see people do this all the time instead of looking at stats and logs) I don't see how an app hibernating an app that potentially causes wakelocks etc by running in the backgorund, can be worse than not doing so.
[Xperia Z Q&A, Help & Troubleshooting] Kocane:
Wow, undervolting makes my phone seriously unstable. -100-150mv it couldn't handle.

BTW, what are peoples experience with eco mode? Is it worth using? Maybe customizing it so more heavy apps turns eco mode off (with faux).

Tell me friends, I can vaguely remember this (the look&feel of the colors when I bought my device).. Is it true that if you unlock your bootloader you automatically lose DRM rights hence gamma setting becomes the way I see it now, and before unlocking BL it was like I make it with kernel gamma settings?

Well, Stock unrooted with around 15 apps disabled gave me this.. Although the whole time, i never played one game.. As i learnt that hot batteries drain a lot quicker(gaming being the cause of heating the phone and hence less battery life), i used my phone in all other terms.. Texting, Browsing, Media, Walkman, Some Youtube as well.. Also Brightness to the minimum(25%).. Well we all know one thing for sure.. 4.3 sucked the hell outta our XZ batteries.. Hope that wont be the issue on 4.4.2.. :)
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
Leaked 4.4.2 Standby!

Ca 7 hours, 1% per hour

Sync! 2x email push and other stuff

WiFi whole time on.

Not sure if I should be impressed or not -.-

Official Sony is strong in this one!

Mmc1_detect is huge when Wlan is activated.

But even tough 40minutes (ONLY lowest freq!) it only drained 1% per hour!
[Xperia Z Q&A, Help & Troubleshooting] Kocane:
Seems the same as it ever was. I can only assume that msm_hsic_host behavior is the same as before too.

I mean, 1% per hour isn't BAD but I wouldn't say it's anything special?
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
meh -.- stuck with a bugged FastDormancy and the old way to solve this problem (as always done on Stock 4.3) doesnt work on Kitkat -.-

As you can see, first i was Charging, then using WiFi standby, then using the phone for about 45 Minutes, after that i deactivated WiFi and went out for 45 mins, came back into a location with bad signal, only edge aviable. 3% per hour -.-

Oh yeah... i'm not sure how Exchange managed to keep the phone 26 minutes Awake... i mean.... it used 1MB ! 1 goddamn MB! assuming it was only 75% of the time busy with syncing we have 20 minutes network connection it would down/upload with 6.8Kbit/sec -.-

using Speedtest.net App i can say that i have 110kbits which would result in 74 seconds for 1 MB of Data !

so WTF is that Exchange service doing? i just have 2 Account with Push synchronisation.
[Xperia Z Q&A, Help & Troubleshooting] Kocane:
I did use the phone a lil bit as you can see, so I suppose it might be a little better than 0,9% drain per hour. It's aight.

[MENTION=3056043]Haldi4803[/MENTION], do you NEED Exchange? I mean, I've disabled it because my gmail doesn't require it, using the Xperia Email app.
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
i do need exchange! I have 2 Email accounts, with Calender that work over activeExchangeSync, also using the Sony Email app.

i had them on Push, but Push seems to create horrible wakelocks when on a bad internet connection.

I know i somehow fixxed that with Greenify on a previous stock rom, on AOSP it strangley isnt a problem at all -.-

One more, of sonys "optimizations" that fail horribly, like the mmc1_detect bug
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
i dont get it!

i just don't get it!

4% Awake time! 26 minutes in 10h30min, all the time on 384mhz !

Nearly no Wake ups, less than 1MB Traffic during that time!

No fast Dormancy bug!

SO WHY DOES THAT CRAP DRAIN 2.5% PER HOUR ? i don't get it! i'm totaly clueless !

i mean... yes... the Radio signal is Bad. but... 2.5% per hour just because of bad signal ? -.-

The only thing i can Think of is some Sensors not really going offline /power safe mode.

Any idea how i can check that ?
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
ehm jep... seems to be a Mobile Data Problem !

Flight mode completly solves that -.-

Just wanted to ask, is it safe to charge phone overnight or will it cause battery life to decrease in any way?
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
I've been charging my phone over night (around 6-10 hours) every day for the last year.

The charger stops charing when on 100% and starts again when it drops under 96 or 94%

btw, Stamania mode helps!

But i'm not sure if it just has better Standby because i most of the time lost 3G connection -.-

at least no more exchange problems ~.~

lets see what we can achiever over WiFI for the next 7 hours :)
[Xperia Z Q&A, Help & Troubleshooting] neyul18:
tips

You should use the SetCPU for save the battery life
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
And that would help what? In the 24 minutes active time, I had about 22 minutes on 384mhz and less than 1 minute on 1512mhz

Edit:

Here comes with WiFI and Stamania mode.....

Still whole lot of MMC1_Detect wakelocks -.-

After that i started to think.... maybe if i block internet access i won't get mmc1_detect wakelock?

So i installed Android Firewall (fork of Droidwall) and whitelistet only the apps i really need.

Seems like i did whitelist to much apps -.-

currently whitelistet even less, and if that doesn't help i'm gonna block ALL apps....

If it still occures then this seems to be caused by the WiFI settings itself -.-
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
phew... i really wonder what sony ****ed up....

I blocked ALL apps with Android Firewall. Even system and Kernel, still Wakelock... so it's not comming from an App.

Or it does not matter if it has Internet and just checks if WiFI is aviable -.-
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
So the overall time me playing around was 1day 14 hours and still 20% left. With only 1hour SoT

And I still have no clue what is causing mmc1 detect -.-
[Xperia Z Q&A, Help & Troubleshooting] Kocane:
How about when using stamina mode with nothing whitelisted? I mean, when I did that I had only 20 secs of msm_hsic_host over a course of 8 hours screen off. Should be the same as blocking everything, but I dunno...
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
Msm _hsic_host only happens when connected to 3g! Not over WiFi (or not as much)

But using Stamania mode without exception would be like deactivating 3g.... Making a smartphone useless!

P.S. Here my daily usage.

Only 24mins SoT, but still 1.8%/h is kinda acceptable.
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
wel.... FTS! I greenified EVERY single App (and system app, Total 240 pieces)) on my Phone, and activated Android Firewall in Whiteliste mode with none (aka all blocked)

Still 7% MMC1_detect Wakelock on WiFI -.-

FU sony !

P.S here is with just Greenified all apps, no android firewall -.- Kinda th same

[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
There must be some way to deactivate Google Backup On 3g (or 2g -.-) right?

Here my last day!

The first part was WiFi on, and roughly 1hour DLNA music streaming. 1.4% per hour because of that.

Then I went to Sleep. 3g activated, WiFi off, Stamania mode!

0% for 6 hours! WTF?

And then I was doing normal things. But not much with the phone.

When you take a look at the graph you see that the battery drains when I have bad signal!

I assume that Google Backup and exchange try to sync even tough signal was horrible and sometimes I had no signal at all!

This caused prolonged wakelocks and drained that battery.

Or its just the bad / always changing from 3g, 2g to no signal which is causing the battery drain!?
[Xperia Z Q&A, Help & Troubleshooting] Kocane:
Wtf? 4 min awake on 6 hours and 0% battery usage... HOW?
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
I have absolutely NO idea!

I did nothing in particular. I used the phone before, so maybe it just dropped a % and I made the Screenshot right after awakening the screen!

But I only had Sony stamina Mode active and 3g connected, always good signal.

Guess no email during that time no WhatsApp and nothing else.

New battery for solve boot loop and not charging problem

Hey guys

Actually after reading this forum for couple weeks I think my Xperia z problem is with it's battery.

Near month ago my phone had stated to hang and stop working some times, I reset it by holding volume and power button, It worked few days and I updated it normally (my phone was done it automatically) and one day after I wake up and unplugged my phone It was turned off, I turned it on and I ran into boot loops, I just saw "Sony" brand and then turn off again, and now nothing happens to my phone when I plugg it in. The only signal that make me feel alive is that when I push the power button, the LED stats to blinking 3 times that mean there is no charge, and when I connect whith usb cable to camputer, I hear the sound and again boot loop appears.

so I read many pages and try everything that you've said here and somewhere else, I updated it first with pc companion, then try to flash it with emma, then flashtools, so there is no different.

I think it must be of battery issue, I even opened the back cover and disconnected the cables. Now I want to know where can I buy new battery for my Xperia Z C6602? whats the battery's properties, I mean I want the right information about battery that I have to buy.

I live in houston, TX

Battery Spikes/Fluctuations

Hi guys,

Tried searching the forum, but couldn't find an exact match to what is happening to my Z - over the last few months I have been experiencing the phone randomly coming up "Shutting Down" even when the battery is fully charged - can get rather annoying as I can look at my phone and it is off, can happen up to 10 times a day. I have since tried a full re-install of the firmware (am on stock 4.4) and wiped the phone to no avail.

h t t p ://s3.postimg.org/q871crrlv/Screenshot_2014_05_26_20_57_50.png (sorry unable to link image due to new user - remove spaces in http)

If you take a look at my battery stats, you can see the percentage fluctuates throughout the day (note that the phone had been disconnected from the charger up until the end of the day)

Can someone advise if there are any steps I could take to fix this? (note that I have previously had to replace the back glass on my Z due to a crack - the two are un-related as the phone was randomly shutting down before this)

Also, would this be covered by warranty? (or would it be best not to claim on warranty due to me changing the back glass)

If not, I am very wary of the batteries on eBay (UK) as I have been stung before with "genuine" items off eBay that are clearly knocked off - can someone point me in the direction of a reliable source for a genuine battery in the UK?

Thanks in advance

Hi battery experts,

Is it possible that my battery of my Xperia Z is damaged after it dropped flat on the screen on tiles?

It dropped from 2-3 feet approx, and perfectly flat on the screen. The phone powered off in an instant, but it booted as usual. Since then it had trouble with charging (sometimes would charge, sometimes not and reject the charger), until it died at 51%. Not it doesn't want to boot, or charge, even though the red LED is lit. Also, there is something rambling at the bottom of the phone. Also, 3 days after the phone died, it started vibrating non-stop on the charger, and off the charger aswell... But I know that working Z's can operate normally aside from the non-stop vibrating issue.

Hard reset doesn't work, and when it turned off at 51%, I pressed the hard reset and it showed met 3x red LED, which means that the battery is drained.

We are thinking about saving the data by opening the backplate, charging the battery with a power supply (in a phone repair shop) and back it up before I send it back to Sony. Is it just a battery issue?
[Xperia Z Q&A, Help & Troubleshooting] Halfsun:
Hi all.

I also had issues with battery when updated to KitKat, but as from 3/4 days ago I think I had solved the issue.

Just FYI (and must say that what works for me does not mean that works for everybody) I uninstalled Google Play Services (defs>apps>transfered).

After that rebooted my phone and opened Youtube (it requested me to install GPS as it was needed to run Youtube).

Installed the "new" version of GPS, rebooted again and for now my phone is working perfeclty without battery drain and without heating in the back.

Must mention that I don't have any battery apps on my phone and with intensive use I still have between 25-35% battery when I go to bed.

Hope it solves some other Z users problems too.

Regards.
