[Q] Battery draining fast when turning on 3g and phone is getting extremely hot - Xperia Z Q&A, Help & Troubleshooting

Got the z two days back, the ph works fine normally, but as soon as i turn on 3g it gets extremely hot and battery dropped from 100% to 75 in 30 mins. No apps are running in the background. Please help me out...
Dont know what to do. Tried updating firmware, but still the same.

What do you mean by extremely hot? (If you place the phone on your skin then remove, does it change you skin colour to a pink hue?) becuase that is extremely hot for a phone (My HTC running turn by turn navigation did that normally) The battery should not drain that fast, the only suggestion I could make is that you might have a faulty unit, it shouldn't do that.

Have you tried to freeze/disable the fast dormancy app which comes with the stock rom?

It's called "com.sonyericsson.android.wakeup".
The files are: "/system/app/fast-dormancy-wakeup.apk" and "/system/app/fast-dormancy-wakeup.odex"
For more relevant info in the Fast Dormancy subject, search it on Google. It can save battery when your provider supports it or drain when it doesn't.

Move the 2 files to another place.
You need root access.

Umm by standby do you mean sleep?

there is an app named Android Status. using this app I can see uptime and awake time. Yes, I mean sleep, low power mode, or whatever u name it. it is important than when my phone is NOT in this mode, it uses too much battery.

If you posted in the QA thread it might help,
Also revision of CM7, kernel etc...
If your on a CM7 < #14 then update.
Also check the inbuilt battery use monitor, it should show what's keeping it awake.
If you want your phone to last on battery, stay away from CM7, it is known to use more battery than stock rom's, 24-26 hours is about the best you will get on CM7.
would u pkease move this to qa?
u khow, the problem is not cm7, I want to know what app is preventing me from sleeping.

i think there is nothing wrong with ur rom there, try to freeze da battery saving app, usually user giving permission to those app to do anything to save battery.
if u want to save battery, using greenify app would be enough.

there should be settings and option in this apps to prevent auto airplane mode. but i don't know how to.
i dont use that kind of app coz its got permission to alter system. so dont quite know bout that, but i already see broodrom, there is no such error so that must be app.

[Q] Charging LED

The Droid 4 is the first phone I've ever had that doesn't light an LED to indicate that it is charging, or indicate that it is fully charged. Is there such a thing on this phone? If so, how do I turn it on? I don't want to have to wake the phone to check the battery level.

ive opened the apk and I don't see bools.xml anywhere
It looks like the free app Light Flow will do the trick, even on non-rooted phones. The app gives me the option to change the colors, even. Nice selection too. The one thing I can't seem to make it do is keep the LED on continuously, even when I use Light Flow's Always On setting. Must be some setting Motorola has locked down. But at least I can tell at a glance whether the phone is charging or not, even when it's sleeping. Plus, Light Flow lets me set the LED to a different color when the battery is fully charged. Awesome for a free app. :good:

4G instead of LTE??

My xperia Z used to display LTE on the status bar with the journalists ROM (4.3). Recently i flashed it with the generic UK 4.3 rom and now it says 4G. Is this normal with this rom? Is there a way to change it?
I think that just depends on the region your ROM is from. I think some marketing regions use 4G and others use LTE. It's normal, won't affect anything.
You could probably go in there and change it to whatever you wanted if you rooted your device.
Yeah it's just a flag set in one of the apk's in /system/etc/customisation/overlay/

Hi,
can you be more precise ? There is a /system/etc/customization but no overlay subfolder (only settings and content)...
Thanks by advance.

The 4G icon is caused by the overlay file /system/vendor/overlay/SemcPhone-Overlay-XXX.apk. If you delete that file, you will get the default LTE icon. However, it's only an icon, it has no effect whatsoever on the connectivity or performance of your phone. I'd recommend to just leave it like it is, to prevent problems with OTA updates.

Yes, that's the one, was just getting to reply but you saved me the trouble, thanks.
Thanks to you both
I have found that it is actually /system/vendor/overlay/SystemUI-Overlay-285.apk that is causing the icon switch. It is the only overlay I keep in my rom for that reason. ?

I'm sorry, I couldn't see the screenshots before. You'll need a better BBS log, it would be much more reliable if you would post a log from overnight. Those one hour logs can't always give a clear enough picture. Make sure you don't use your phone, so we have a completely idle log.
Check the BBS thread for AlarmManager, that should already give you quote some pointers to work with.

The whole point of doing a thread here is so i don't have to send phone to sony to repair
Even i know i could have the phone repaired! Don't wanna spend money on repair
Phone works fine just the battery issue as mentioned above
Don't want 4.3 due to all the bugs mentioned here

Well, without a better log, we can't help you. 'Android System' contains just too much functions. It shouldn't be a problem to just get an idle log off 4hrs or more, to help solve your problem, right?

In the above quoted thread someone said the majority of the alarm manager wakelooks being Google Talk and Facebook. I concur and think these are among the first things to kick from the phone. Do you also have NFC on? Widgets on your screen?
Actually it sounds as if you did already a lot. I am not sure if I would further bother with this ROM,whatever it is.

Some disabled apps still "work" in the background. NFC for example. Or GTalk.
Investigation of these sort of wake-locks can be tedious. Unless you see it as an interesting task Did you consider simply re flashing it?
