Today, second day with my Xperia Z:

After 13h of use my phone has still 42% of charge.

I work in the Web industry so in office i can message, get into social networks, use it like hotspot, listen to music, use whatsapp, download Apps and with all this use the phone has extraordinary battery life!

I used Stamina mode and i set up it so that email, sms, whatsapp, nfc, wi-fi auto turning up on location are on.

Amazing!

The only ugly thing is that stamina mode shows me 4 hours of standby left. But that's not true :)

Re: Xperia Z battery life

Interestingly enough, battery life just seems to be almost 85% software related. Back when we nexus 4 users were still on 4.2.1, most of us barely reached about 2 or 3 hours screen on time with moderate usage. But once we had 4.2.2 in our hands, MOST of us suddenly had 4-7 (some got 7 hours, really) hours screen on time on average for moderate usage. So don't lose hope guys, lol.

I'm posting here despite me owning a nexus 4 because I'm really interested on the xperia z :p

Xperia Z battery life

I'm on holiday in Rio, taking loads of photos and HDR video, maximum screen brightness, wifi on permanently and no mobile signal, not sure how that affects battery life as its switched on but my network is not compatible out here (3 UK) and I've got just over 3 hours screen on time with over 19 hours total. So I'm really pleased as its much better than my One X that I had before. I've been using stamina mode. Hope that helps.

The problem is something stops Stamina Mode and it's nothing that actually tells you it's doing it, it's some other process not an App.

Re: Xperia Z battery life

Both my N4 and XZ have spells where the battery lasts as 2 minutes or less for each 1 per cent. Doesn't even seem to be under heavy load either (app wise).

My XZ is currently showing 5m 59s per 1 per cent. All I am running is Tapatalk.

Battery life is an issue on all the latest high end devices.

NOT the same

They are not EXACTLY the same. The actual CPU is VERY VERY similar, however the memory used by both systems is completely different, which results in a large impact on performance. This user sums up the differences much better than I can :

http://www.pocketpc.ch/c/3662-mwc-2013-exklusiv-qualcomm-snapdragon-600-entspricht-snapdragon-s4-pro.html

Look at any benchmarks and it becomes clear that these are entirely different SOCs

(Anyone who says benchmarks are meaningless, doesn't understand the definition of a benchmark. Without benchmarks we would have no way to gauge performance improvement, and technology WOULDN'T IMPROVE. Sure you may not CARE about benchmarks, but they are in no way meaningless )

First time using after 100% Charge. Did make a few Fotos, Lot of surfing ... WiFi Only! No SIM card inserted! Some benchmarking... and around 1.5h Throwing videos to TV.
[Xperia Z Q&A, Help & Troubleshooting] Sunnychad:
Well I have read a lot of comments battering the battery life but this is my real world experience and I would say to compare with my iPhone 4S

I used the phone a lot today, well by my standards at least. I drive a lot so like to make calls between appointments so today I got 11 hours of total use before the phone died;

3 hours of talking on the phone

2 hours of screen time

About 30 emails sent

50 or so whatsapp messages

A lot of time spent viewing and assisiting the finetuning of our CCTV system 100MB of data download as part of that

Bluetooth on in the car so about 7 hours connected

A bit of surfing, but not too much about 30 mins worth

Used Stamina mode not that it increases battery life by much (help on this would be appreciated)

By contrast today the iPhone 4S was in my pocket pretty much all day but was used a bit

40 mins of call

Received emails

5 whatsapps

No Bluetooth

Wifi on not connected

Screen time, very little, probably less than 30 mins

Battery life left at the end of the day 35%. Had I used the iPhone 4S in the same way as the Xperia Z I would have plugged it in for charging by around 3pm knowing how it drains once you have only 20% left.

I would say that's a fair battery in these modern days of 1080P 5" screen and quad core processors. Does anyone agree?

[Xperia Z Q&A, Help & Troubleshooting] JPWOA:
Something might be wrong there...

You have high Android System percentage! And if you notice the graphic is a continuous blue line! There should be gaps from when the phone is sleeping!

I had that a similar problem and did a reset last night! When to bed with 100% and woke up with 100%! Checked the graphic and had no blue lines during the time I was sleeping!

And the Android System was around 7-9%
[Xperia Z Q&A, Help & Troubleshooting] AntonyStark:
Re: Xperia Z battery life

That was the Wi-Fi line.

Here's where I am now, the phone did wake up during the night as you can see from the start, but it's not as bad as the day when Devices was 28%!!

3 hours 45 screen time so far.

Having a problem understanding the stamina mode. I 1st started using it and when I turned it on, the phone started reporting 2 days, 5 hours of battery in standby mode. I only have facebook and google chat added to stamina, everything else shuts down... Now, the phone is at 70% battery and it only says 16 hours of standby..? Is this right? Yesterday I had 50% battery and it said 1 day, 6 hours..?! Is this thing broken..? I really don't have a lot installed. Also, I love getting theses messages saying... google maps, google apps is preventing stamina mode from working and try force closing it... What the hell is the use of stamina mode then..?!

Re: Xperia Z battery life

Experiment over, Stamina Mode on, low battery mode on at 6%
[Xperia Z Q&A, Help & Troubleshooting] Haldi4803:
Not at all! Always depends what you're doing! Web Surfing and SMS normally uses way less energy than playing Games!

As you can see i didn't use the Phone for 7 Hours... and then played around 1-1.5h Arcane Legends that really drained the phone!

Different actions use more or less energy! Nice to see with CoolTool power stats in Antutu Benchmark: Idle is ~300mA as you can see in the Screens above.

If i ever have to much time i'm gonna activate the Log and check out the average drain from stuff like making pictures... listening to Music... Screen off / with Stamania Mode... amm.
[Xperia Z Q&A, Help & Troubleshooting] gm007:
Re: Xperia Z battery life

Stamina calculate the time left every 5 minutes,so in this 5 minutes you where playing a game for example the time left will be shorter than if the phone was idle. Hope this is clear for all people wondering whats wrong with stamina.

Re: Xperia Z battery life

Hi,

Just wanted to share my experience. The first evening after charging I only got 4 hours of screen time and I was very unimpressed. The next day I turned on stamina mode and used it as I normally would (not constantly loading new stuff and tinkering) I got much better battery results.

I've attached some screen shots.

Loving this super slick phone, it is a great upgrade from my old iPhone 4.
[Xperia Z Q&A, Help & Troubleshooting] jkwanness:
It seems like my Stamina mode is dead. Turning it on or off doesn't change the estimated idle time.. Is there a problem?

Mine changes Barely, by an Hour but can standby much longer than it is saying. I don't know how it recalibrates as mine has not said Days of Standby since the beginning.

Brilliant phone with terrible energy consumption

I'm reading posts of people who are praising xperia z screen-on battery life and wondering maybe they got something different than I have. Maybe my XZ is defective... With full brightness and wifi on it drains 2% per min. With close to minimum brightness and browsing internet via wifi it loses about 20% every hour. And one more thing that surprised me is when phone is connected to laptop and is on heavy usage, the battery still drains rather than charges (but drains very slowly, when connected to laptop). Although on stand by and stamina mode on this phone would last for a week if not more. Despite it's battery, XZ is worth every $ spent on it. Performance is super fast, screen is flawless. For people who are complaining about screen (it's strange, but I saw few posts of them): show me a phone with better screen than XZ. And check if Bravia engine 2 is activated. Watching full HD videos or photos is like watching through window (just a little more beautifull). Colors is more realistic than super amo led's. My verdict: 3/10 to a battery, 10/10 to a phone (I would give 11/10 to a screen!).
[Xperia Z Q&A, Help & Troubleshooting] arcwindz:
Don't use 100% brightness, 50% with the "adapt to lighting condition" ticked should do the job. Other than that, it should be about the setting on the apps, etc

The charging speed is a real problem though, has been hearing about it everywhere lol
[Xperia Z Q&A, Help & Troubleshooting] TeeJayEss:
Got my XZ a few days ago, and the battery life has got better since the start - perhaps the battery being conditioned or something? Either way, I would say it's at least as good, but probably better than the Galaxy S3 it replaced - ie. I have a bit more left at the end of the day than I did on the GS3, after similar use.

What's also interesting is that the battery percentage is tracking my work iPhone 4 like for like through today, even though that's had less use, and they both came off charge at the same time.

Not tried Stamina mode yet, not sure I need to...
[Xperia Z Q&A, Help & Troubleshooting] lysergicious:
Yeah, I just wanted to check how fast it will drain on full brightness. View is best on 50% brightness, but I use only 15 - 20% to save battery. I remember there was stick on phones back which shows that first time you need to charge only 30min. First time I've charged for about 4 hours. Maybe that could damage it's battery? And what those 'cycles' is? It means fully discharging and then fully charging? From a different sources you can hear different things. I doubt fully discharging would extend battery life. Somewhere I've rode that for lithium battery isn't good to be fully discharged, less than 20% left can damage battery. I never let my laptop to discharge less than 20% and after more than a year of everyday use, battery wear level is still the same (lasts 10 hours of normal usage). I'm not an expert, maybe with phones is a different situation. That would be great if my XZ would last at least 8 hours screen-on/wifi-on.

[Xperia Z Q&A, Help & Troubleshooting] charlodroid:
Had mine over a week, (since the 28th Feb), and I am loving the battery life. Sure when the screen is doing it's stuff it uses a fair bit of juice, but what do you expect with a big 1080p display and quad cores. But with the screen off and stamina mode on it barely touches a drop of juice, it's amazing. I have already come to expect that when I wake it up it will have exactly the same amount of juice as when I put it to sleep, even overnight. I am not running any apps in the white list to stamina mode though, and I am only updating apps when I need to rather than whenever they want to.

On the whole I love the phone. It's a classy piece of kit.

Yes, on the image below the phone is charging as I had just turned it on as an hotspot and had to set off to work before long so I wanted it fully topped up when I set off. But as you can see from the graph, overnight it didn't use a drop of juice. The graph doesn't even look like a graph because it hasn't changed. Amazing.

[Xperia Z Q&A, Help & Troubleshooting] charlodroid:
No. It wasn't charging all night. Look at the blue bit underneath the graph, that was the usage. My phone wasn't on charge all night, it was just on but not being used.

It lasted 11 hours+ and didn't drain a bit.

It was only on charge at the end of the graph. I just happen to have put the phone on charge just before the screenshot to keep it ready for when I set off to work, I was using the tethering as I took the shot and didn't want the tethering to drain the battery.

11 hours on and zero drain is the amazing part.

Ok, when you use the phone it will use the battery, but provided it is charged when you start out you will have a full battery to use whenever you need it. That means when I take it off charge before I go to bed tonight, and then go on a mission tomorrow, when I find something I need to do I will be starting with a full battery. On lots of other phones if I did that I would set off out tomorrow, have some breakfast and maybe some lunch, then when I find something interesting to photograph or need the navigation I would pull my phone out of my pocket un-used and be starting with 75% charge. That's 25% less battery to use actually doing things I want to do.

All the battery in the world is of no value if you have used 25% of it while it sits in your pocket.

ps, I went to work today and it was busy so I didn't use my phone a lot. I downloaded a couple of apps and browsed for about five minutes. I spent a little time comparing video with my mates SIII and downloaded and assessed a live wallpaper. I made two five minute phone calls. Like I say, busy at work so really minimal use of the phone, but still when I got home ten hours later I had 92% battery. It's horses for courses to a degree. If you use your phone a lot it will eat the battery. But when it is in your pocket it won't. I like it. when I use it I am aware of how much battery it has so I know if I am going to need a charge. When I am not using it it isn't using any. I think it's a nice compromise.:D

Re: Xperia Z battery life

Your Note 2, Motorola RAZR Maxx and RAZR Maxx HD, and likely the upcoming LG Optimus G Pro are the exceptions, because of the small nuclear reactors for batteries powering those phones. It's unfortunate Sony and HTC couldn't put 2700mah batteries in their phones. I'm willing to bet the Galaxy S4 comes with at least a 2500mah battery, and probably closer to 2800mah.
