Since my iPhone 5 manages 6/7 hours. (And no I'm not a apple fanboy) 3h is rubbish! My S3 managed just over 4h and i know the Z has a bigger screen and resolution but no excuse for putting small batterys in phones that have big screens and high res.

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.

Yeah I guess so, I was just dissapointed to see that as it reminded me of the One X and Nexus 4, I hated both for that reason..

Screen only making up 26% of total usage? Something seems off, have you investigated for unnecessary wake-locks? Mediaserver is taking up way too much battery

indeed normally the screen uses a much higher percentage.

Same here, my Note 2 on average gives me 5hrs screen on, at a push I can get slightly higher but my brightness has to be really low. Those shots above look good to me, they are without stamina mode on aren't they?

Correct no power saving features were turned on.

Saw that. Not sure why the media server would show up like that. I've just managed to get the device to die on me so I will charge it up and see what it's like tomorrow. I installed BBS also to track wakelocks.

maybe BBS interferes with Stamina mode?

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

But doesn't this method make those statistics a bit fake ? Never heard that iOS does it this way.

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.

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.

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

I just installed it. All the previous stats were without it installed. And I don't have stamina mode enabled anyways.

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.

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).

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

Maybe you can clear the cache, i have had something similar with the download manager

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.

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.

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.
