Well, even a screentime of 12,5 hours seems plausible! I was wondering what the contribution of the screen on the batterylife was by *only* enabling the screen.. What does this prove? Nothing! At least I can start looking to other causes of my rather poor batterylife.

Conclusion:

Dont just look to the posted screentimes, they are rather relative..

Can anyone tell me how to delete the mirrorlnk thing??And does this have any effect after deleting??And which other system apps can be deleted??
[Xperia Z Q&A, Help & Troubleshooting] 23Six:
User gm007 has a list of all .apk's (system apps) that can be deleted without hindering device.

To delete system apps navigate to /system/app and delete away. Or do it the safe way and install Chefs Freezer from Play and go magic.

Deleting mirror link will only mean you can't use the feature.

This prevents to phone from switching between the networks and can save power.
[Xperia Z Q&A, Help & Troubleshooting] 23Six:
I have poor 3G reception where I live so forcing 2G helps. Also a strong 2G will consume less power than a strong 3G.

Turning data off doesn't switch off 3G radios, just blocks traffic. Proof is in Settings>About>Status.

What bloatware prprograms should/can be removed?

Sent from Xperia Z
[Xperia Z Q&A, Help & Troubleshooting] Nameless One:
Anything you aren't going to use or don't want, if you like/need a particular program

then it is hardly bloatware any more. Anything that can be regarded as unsafe to remove

probably isn't bloatware.

Removal of some things may require the phone be rooted and something like Titanium backup used

(and it might be a good idea to back up anything first before removing it, except facebook which can

go far far away never to be seen again).
[Xperia Z Q&A, Help & Troubleshooting] drsoran2:
To those complaining about awful battery life. I have the phone now for 10 days and this is my battery life: 1d 8h off charge, 4h 12m screen on time! What I did in this time: whats app, phone calls, ebay, e-mails checking, facebook, twitter, instagramm, web browsing, browsing pictures on my phone, use it for sports app about 30 minutes.

Now, this is WITHOUT Stamina mode enabled. I turned Stamina mode on now after a full recharge and will see how it goes. Currently, it gives me an estimate standby time of 4d 19h, without Stamina it's 1d 16h.

I've never had such a good battery life with my previous smartphones (Xperia Arc and Galaxy S2). And you also have to keep in mind, that these were a lot less powerful and had smaller screens to power than the Xperia Z.

Lately, my XZ remained on 100% charge over night (5 hours).

When I was jogging, I used a GPS tracking app, poweramp music player on full volume and a bluetooth heartrate belt all at the same time. After 20 minutes, I checked my phone and the battery was still at 100%. At the end of my jogging, it was a total of 1:20h, I only lost 5% battery!

I'd say that this is incredible.

The standby time of the Xperia Z is really really good.

But keep in mind that it depends on so many factors: number of apps running in the background, syncing accounts, cell reception, what types of apps you're using (heavy games!),...

I for myself have only the google account syncing, I limited background data transfer under settings for most apps which don't need to do that and I use greenify and "greenified" some apps like facebook. It works like a charm and facebook doesn't pop up under running apps all by itself anymore like it used to be. It only starts when I open it manually and after that gets greenified again.

Sorry for the dark screenshots, I had "screen filter" app enabled.
[Xperia Z Q&A, Help & Troubleshooting] zalman360:
It may be stupid to ask .... But how can I know if I have a defective battery ... All these setups and battery strategies are driving me nuts !!! My friend has one and told me that sometimes it lasts a day and sometimes not even 3 hours with all settings and apps always the same. Does quick charging ruins the battery stability cos I think that's his problem !!! ( Btw he limited apps to 2-3 like FB etc with stamina mode and 2g only no data connection and occasional wifi ). Screen is auto and 35% always.
[Xperia Z Q&A, Help & Troubleshooting] wawyed:
Depends what does he do while the screen is on? CPU intensive talks? As always better battery stats with partial wake locks, alarms and others helps to see if there is a problem with an app.
[Xperia Z Q&A, Help & Troubleshooting] zalman360:
Nah he's just a simple user ... facebook , Walkman and firefox. No games or heavy quadcore usage. One thing I forgot to mention is that he uses 2g as standard and when reception is low you see the percentage going down by one every ten minutes !!! once he told me that battery percentage went up again from 78% to 80% while screen off but that's a stamina mode thing I think... Any way on Sunday will examine his handset again and check out bloatware n running services again.

Nothing of this is correctly, i have my phone for 3 days most of the time.

It's a bug, you can go to all apps & click on force stop/clear data under 'eco mode controller', then restart the phone to fix this temporarily (may have to try a few times to readjust the estimated batt) but it will come back after a few days. I think the next patch/update will fix this though.

Sorry if I am quoting an old post, but I'm interested in knowing whether or not you are running on stock ROM and not rooted, or you have tweaked your XZ in anyway to improve its battery life.

Right now I'm actually planning to buy either an XZ or LG OG to replace my SGN2 (not comfortable with the size). When I read www.gsmarena.com about its battery life, I found out that XZ is far worse than SGN2, especially at browsing and video playback, both of which are my biggest concern in an Android phone. I don't make much phone calls, and am more into using social apps or browsing.

So, do you guys think this is a good replacement for SGN2? I don't really like the FullHD screen as I think it may be responsible for worse battery drains.
