AW: Xperia Z battery life

No, it's not only XZ or SGS3. It's the usb standard, so it's all usb standard compliant devices.

Charge your device overnight. I do so, I'm at 100% every morning. I don't use my device duing the night though...

This is interesting. What do you do during that time? I get about 1% per 1-2 minutes with screen on, auto brightness set at about 30% just letting the device chill on the table while being connected.

There is no such thing as battery calibration on Android. The percentage is calculated basen on values read out by a piece of hardware. And those values are predefined, everybody got a 2300mAh battery, that's what the values are based on.
[Xperia Z Q&A, Help & Troubleshooting] waveloom:
There is, and has been discussed for 5 years, since first Android devices realized, and is matter of dynamical measurement of the battery amperage, also several cheats have been released to manually set measurement values.

No Android phone has a good battery life. The Note 2 arguably got the best one but even that isn't great. Nowadays if you don't want to keep a Nokia from 2002 or whatever which lasts for weeks than buy a smartphone with removable battery and keep one extra charged battery with you, it's what I used to do.

[Xperia Z Q&A, Help & Troubleshooting] schaggo:
AW: Xperia Z battery life

Correct. Measurement is done dynamically, based on a readout of a piece of hardware. No statistics are used.

As for the link you posted:

Android does this on its own at every full recharge. That file gets deleted as soon as the 100% (or so) mark is reached. On top of that, this file not used in the percentage calculation, its only holding a couple of statistics, like wakelocks, communication subset statistics etc. Its representation is the power usage graph, posted many times over and over again, in this thread.

Anyone else notice the com.sonyericsson.dlna.Devices process keeping the system awake? I just noticed today that when I turned my Xbox 360 on the throw options popped up and I could throw media to it. Played around with that for a little bit and later when checking my battery usage noticed the Devices app/service was high for battery percentage used by app. Even after I turned off my Xbox 360 and turned off the settings under Settings->Xperia->Throw settings Devices is still keeping the system awake.

I had to Force stop it for it to stop keeping the system awake. Once I did that I turned the Xbox back on and didn't throw anything to it and the Devices service was good, it didn't keep anything awake until I actually threw media to the xbox. Then once again even with the xbox off it was keeping the system awake. Seems like the service doesn't recognize the xbox is gone and can stop keeping the device awake.

Yes this happens, I don't throw anything now as it affects battery life for the next day or so.

Mine seems to vary, even with the same usage. Sometimes I can charge (overnight) and it will stay on 100% for 2-3 hours, other times it will drop 2-3% in the same time. Thats with screen lock, no calls/texts/whatsapp/Facebook etc. Just sat in my pocket. Most I've had is 36 hours with moderate usage, stamina mode active. Other times with same kinda use, I will have to charge before end of the day. Stock ROM, only whatsapp downloaded.

Re: Xperia Z battery life

You graphs and awake times and screen On marks look normal, how is this even bad battery life? You would have to use the phone to run down the battery and if you did the screen would be higher and Android OS would be lower, so you're not comparing like for like.

Hi my Battery lasts the day with average use I think, my point was that on looking at what uses battery the Andriod O/S is eating a large amount when compared to others here.

[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
Re: Xperia Z battery life

Like I said it is better to compare your phone to others when it's nearly empty, not at 75% at that is pretty much dependent on what you use your phone for first. But I understand what you are saying.
[Xperia Z Q&A, Help & Troubleshooting] cheltenham2004:
Yep get what your saying For example my battery is now at 53% and the Andriod O/S is at 33% full time on battery thus far 11hours 12mins
[Xperia Z Q&A, Help & Troubleshooting] schaggo:
AW: Xperia Z battery life

These graphs are relative. Meaning: all added up, need to give you 100% at all times. If you don't use your device at all, the screen will consume close to 0% thus the whole consumption goes to... yes, your system and it's components. If you have the screen on full brightness and on all the time almost all percents will go to the screen and almost nothing - relatively - goes to the other components.

Basically you could say, these graphs don't show how much energy you used, but where the energy went, which you did use. So if you didn't use your device at all, yes, all energy goes to your system, predictably.

Good Battery Life

Had my Xperia Z since the 5th March and I get 15 hours out of it with average use and the screen on minimal brightness (I like my screens dark).

With light use my Z will sometimes last around 2 days, but that's with light text messaging and the occasional call.

Obviously this is with battery STAMINA mode turned on.

Push notifications are turned on and the only apps I have exceptions for as far as STAMINA mode goes are Facebook, Gmail and the Native Android Email application.

I have a live wallpaper applied and run Avast Mobile Security in the background as well.

Main battery draining app is a system app called Mediasever which takes a considerable chunk of the battery (15-20%) according to the internal battery graph thing in settings. I haven't looked that much into this but from the little research I actually did returned that it was some glitch with jelly bean 4.1.2 but don't quote me on that.
[Xperia Z Q&A, Help & Troubleshooting] Akiainavas:
iPhone is different. It's well knows that iOS devices have better battery life. Lets compare Android with Android - which as we all know doesn't manage power very well ( at least not as good as iOS or Windows Phone ). I'm pretty sure you'll be able to get 4h+ screen time - it depends on what Spectre has been doing with his phone.

Re: Xperia Z battery life

The iphone's "usage time" is not the same as the screen on time of android. The iPhone logs usage time anytime it does anything, like synching and such, weather the screen is on or not. Big difference. Not hating on anything, they are just different measurements
[Xperia Z Q&A, Help & Troubleshooting] Akiainavas:
But doesn't this method make those statistics a bit fake ? Never heard that iOS does it this way.
[Xperia Z Q&A, Help & Troubleshooting] hebbe:
they don't care about true and reliable statistics! marketing is everything! a phone that lasts 20 hours of usage is better than a phone that does only 8, isn't?!

remember when they introduced copy, cut & paste in iOS3? revolutionary! the best phone and os around! everyone believed! that's marketing. my old sony ericsson phone from 2003 was capable of copy&paste, but they didn't shout it loud, because it seemed "natural" for them. :D
[Xperia Z Q&A, Help & Troubleshooting] Akiainavas:
Ah yes. Apple is the master of presenting old things as new and revolutionary, things that has been in use for ages, they invented so many things like video calls, instant messaging, folders etc. :) Putting sarcasm aside, they have amazing marketing division - it's often false marketing, but its results are amazing ( then again, most companies lie to us, so it's not just Apple )

Since I rarely use more than 1,5 hours screen on time a day - I'll be more than happy if my phone lasts 48 hours, and from all the reviews it seems that with such usage - it will.
[Xperia Z Q&A, Help & Troubleshooting] stefanve:
Not sure I agree, it really depends on the device, for instance although I use my arc s more than my wife uses here iphone 4s here phone is out of juice faster. while it may or may not be the case that iOS is better in power management (and if it was ever the case if it is still today). the size of battery and the power consumption of the h/w is at least as important

since using it today I can definitely see something is eating the battery. Not sure what the media server is, but I'm thinking it had to do with the smart wireless headset pro I setup. Since I paired it to the phone the throw option had been present to toggle between using the headset for audio out phone speakers.

The actual media server settings for sharing to other devices is disabled. I'll keep paying with it today and post stats later including BBS stats.

This is BBS so far showing the phone isn't sleeping.

[Xperia Z Q&A, Help & Troubleshooting] Ambroos:
It's an educated guess based on my experience today, but I think background audio playback (and some other playback stuff) falls in the Mediaserver category too. With all the delegation to other parts of the OS going on in Android it's not easy to keep track of what is doing what. I've listened to around 15 minutes of music on my Z so far (with Spotify), and I have around the same time listed for media server. Spotify actually had less time active.

Simple explanation: Spotify/Pandora are front-end apps. They download the data, present you a list of songs and manage playback. When you actually play a song they instruct one of the Android Mediaplayer classes (or something similar) to start playing this or that specific output stream in a service. When playing in the background it's probably the media server/Android media system that is handling the playback and keeping the device awake, which is why it might show up on the graphs.

(As another example, data usage for YouTube doesn't show up in the YouTube app but as Android System. Pretty weird but that's how the system works).
[Xperia Z Q&A, Help & Troubleshooting] djq:
usually the media server is a broken photo.....i know it has happened on two previous android devices...usually it happens with a picture sync (like facebook or dropbox) or a screenshot is taken but gets stuck in kind of a loop for whatever reason (i know this sounds crazy but it was my mediaserver problem both times)

usually what you can do is to just delete all the pictures and the mediaserver usage goes back to normal

I'll try removing all the photos and videos on the phone (had left all the stock ones it came loaded with) and see if that changes anything. Today more so than the past two days the battery is really draining fast. My friend's isn't draining like mine so it has to be something I loaded or one of the devices I paired it with.
[Xperia Z Q&A, Help & Troubleshooting] Spectre51:
Re: Xperia Z battery life

So I watched it for a while and the media server never used much battery until I started playing Pandora then I saw it jump up in the battery usage. So it does look like background audio playback does show up as media server as well as Pandora. Still watching it today to see how things go.

So after removing all the photos and videos from the device things seemed to have settled down. I haven't used it as much today but currently I am sitting at 10h 22m on battery with 1 h 51m on screen time with 58% of the battery left. Maps shows a keep awake for 48 minutes which seems like a lot to me since I haven't used the map app or anything that relies on it today that much.

I did have bluetooth off all day as well. Will have it on all day tomorrow with the smartwatch paired and will have the smart wireless headset pro connected for about an hour. Will see how it behaves once I connect those again.
[Xperia Z Q&A, Help & Troubleshooting] Ambroos:
Re: Xperia Z battery life

Most apps that use GPS or embed maps somewhere (Facebook, Foursquare, ...) trigger a Maps wakelock that keeps the phone awake until it gets an accurate location or times out. Google Now might also trigger one when it decides you're probably in a different location and it wants an update, but I'm not sure about the last.

Bravia engine turned off.

Screen set to auto brightness.

Stamina Mode on

Moderate use of WhatsApp and k9 mail.

Low Facebook use.

Voice call total of around 5 minutes.

Used as a wifi hotspot for 10-15 minutes.

Played Real Racing 3 for 10-15 minutes (maybe?) before going to bed (The small dip before the long tail at the end)
