looking at various benchmark scores and self experiences, Xperia Z drains a lot of battery while video watching and internet browsing. Turn on the power saving settings in the settings of Android. Location based WiFi is good. It is not easy to get a free wifi in india, but whenever it is available better use it than the data usage on your SIM
[Xperia Z Q&A, Help & Troubleshooting] jonmorris:
Like the Nexus 4, screen on time is a big drain - as you'd expect.

When using the phone for even relatively simple apps, the battery will drain a lot - but you can manage that and limit your use if you need to prolong battery life. The power saving options won't really help much here, beyond turning down the brightness. Unlike the HTC One, there's no option to limit CPU performance, for example.

In standby, there can be big savings to be made. My problem is that on occasion, the phone can fail to go into deep sleep and on others, I can take it out of my pocket and it's red hot - and the battery is down to something mad like 20% in barely any time at all. There won't be any apps loaded that could explain, and I am now left with a nearly dead battery before lunchtime. It isn't just the XZ that does this, as I've had my N4 go mental too - running at nearly 48-50 degrees!

I can only assume there are some OS issues, but fortunately such occasions are rare - but it's always a gamble when you're going out for a long day and the battery just dies for no reason. I therefore always carry a portable battery charger (7,000mAh) so I can top up on the move, which is a must for any modern smartphone unfortunately.

Mobile data is the final big-drain, and if you have variable reception then it can also mean killing the battery in no time. As such, Wi-Fi is a must wherever possible. I've even on occasion used a portable Wi-Fi hotspot with my XZ instead of using mobile data directly with a big improvement on battery drain.

re: Outdated?

Really? Outdated tech? Really?

This is the newest and best selling DoCoMo phone here, in Japan, where *normal* people (i.e. not mobile nerds) replace their phones every 3 months. There was just recently an article on ArsTechnica or AnandTech about the new processor, etc.

You can say the battery life sucks if you want, but... it sure as hell isn't outdated. It's far faster than the average phone in consumer's hands now and has much higher than average memory. Sure in five years you will see them going for $50 at yard sales, but until then...

Also, I don't charge mine every 4 hours. The battery life is, I would say worse than my Galaxy Note, and certainly worse than the iPhone - but perhaps the same as my Acro HD and better than the Mini. Leaving WiFi on all day and Stamina mode off and Skype, etc. running, it can easily last all day. (Assume you aren't actively using it all day because you have a job where you have to work).

---------- Post added at 03:50 AM ---------- Previous post was at 03:38 AM ----------

Actually though, I don't think the screen on battery life should be very different for the same device. iOS devices have battery battery life because they aggressively prevent background tasks from running. What can run and when is very very restricted. That is good (for battery life) and bad (for flexibility). I don't know if it's about managing power "better", such as managing it differently. I like being able to leave Skype running constantly to receive incoming calls reliably.

When you have the screen on, you are probably using an app, so:

1. Depending on the app, it is probably using the processor and drawing power

2. The screen is on and drawing power

So Android or iOS, an app is running and drawing power and the screen is running and drawing power, so background apps matter much less.

Also, as for including "small" batteries with phones - if they made the phone twice as thick and charged more for a bigger battery, someone would complain about that too. There is a trade-off at some point.
[Xperia Z Q&A, Help & Troubleshooting] :
Engadget and V3 are quoting really bad battery life, is this genuinely the case for you guys who have one?
[Xperia Z Q&A, Help & Troubleshooting] Ambroos:
No. I'm actually pretty happy with it. The display is a big drain on high brightness but as long as you keep it in check you get a pretty good amount of screen-on time from it. Five to six hours isn't a problem (on WiFi).

More importantly, there is very little battery drain in standby. I have mine in Stamina Mode with five exclusions and the drain is less than one percent per hour. With WiFi it's only one percent every four to five hours and that is very, very impressive.

I usually end the day with 40 to 50 percent left, and that includes a lot of time spent in an area with very, very bad coverage. Much better than the Xperia S and T.
[Xperia Z Q&A, Help & Troubleshooting] :
Thanks mate, put my mind at ease. Engadget are properly slating the battery life.
[Xperia Z Q&A, Help & Troubleshooting] DakiX:
Hi i have the XZ and it came with 74% .. I installed it and played with the great phone: apps installed, set up accounts, twitter, pictures and videos about four hours and still had 46%. -28% also in about 4 hour (display on) extrapolated it will tell a nice value but you can say really only after 2 weeks :D
[Xperia Z Q&A, Help & Troubleshooting] :
Battery life is a massive factor for me, I'm such a heavy user. My phones are always on charge though but like to know my phone will last the day if I'm out say from 3/4 in the afternoon till 2 in the morning. Stamina Mode will be on straight away when mine comes. I don't care about notifications from apps that much.
[Xperia Z Q&A, Help & Troubleshooting] dibdin:
How long should I leave the battery for on first charge?
[Xperia Z Q&A, Help & Troubleshooting] DakiX:
I'm Note 2 fan. So I'm used to long battery life. On 10 display and 10% is grade standard (with custom kernel and corresponding ROM) but the XZ it looks good and the STAMINA mode is cool ..
[Xperia Z Q&A, Help & Troubleshooting] Akiainavas:
According to Sony:

30 minutes before first use. Then discharge to almost 0% and charge until it's full. No need to "format" the battery.
[Xperia Z Q&A, Help & Troubleshooting] Ambroos:
Easily. As I've said before battery drain in standby is extremely low, and I've only tested with data connection always on. If you use Stamina Mode without exclusions it'll kill the data connection when inactive and you really won't see it drain a lot.

Mine lasts all day (8 in the morning to 23 at night) with about 1/3rd spent on WiFi and everything else on always-on HSPA+ and a comfortable margin. I've never been worried about the battery life on this phone to be honest.

Re: Xperia Z battery life

Its kind of weird. Comparisons are showing the XZ gets worse battery life than the HTC butterfly (by quite a bit) and the butterfly has almost identical components and a smaller battery. Perhaps the XZ screen is more power hungry?? Or some included Sony software is a big battery drain...

Not trying to bash the phone I am just wondering how this can happen.

Just look at the battery comparisons between the Nexus 4 and the LG Optimus G. Identical phones.... and the Optimus G gets WAY better battery life (Almost double in video playback)

Sv: Xperia Z battery life

[Xperia Z Q&A, Help & Troubleshooting] Ambroos:
I have the LTE model with LTE off (my provider doesn't offer it yet). I have tried a prepaid card from an LTE provider and the results were similar.

https://www.dropbox.com/sc/vmsvdnymmn2ojk6/JBC7JRBf3Y <- These were of my test day on LTE (bad reception in most places where I was for longer periods) with some heavy speedtesting at certain times. I get more screen on time now.
[Xperia Z Q&A, Help & Troubleshooting] :
Hold on, only over 2h screen time? Glad I ain't got LTE yet then...
[Xperia Z Q&A, Help & Troubleshooting] Warrimonk:
Yeah.... 5 hours is terrible compared to the Droid DNA/HTC Butterfly battery life. That review says 4 hours of media playback and the Butterfly gets 7.5

http://blog.gsmarena.com/htc-droid-dna-takes-battery-tests-heres-what-it-scored/

GSM Arena said they will use the Xperia Z in this exact test and give the results by the end of the week. I will be looking forward to the results.
[Xperia Z Q&A, Help & Troubleshooting] Ambroos:
I did a LOT of speedtests there and was in a very bad reception area a lot of the time - those things don't help to keep the battery alive.

As you can see when the display is off the battery drain is very, very low (that flat line).
[Xperia Z Q&A, Help & Troubleshooting] kyogiro:
Well, HTC has been working hard in battery life department since hard (true) critics went down on the HTC One.

One X+ is among the top dogs while the Butterfly is average good.

In the meantime, Sony hasn't been improving a lot throughout 2011-2012 battery life wise. That's also maybe why they put the Stamina on the XZ in order to resolve somehow some integrations problems through an add-on software (not saying it's not good, haven't tested in day to day use the XZ).

The same goes for Google and their Nexus devices, while having great softwares, somehow, when they mix up their top notch software with the hardware, battery life seems to take a hit (Nexus One, Nexus S (maybe the less problematic), Galaxy Nexus (known battery life issues), N4 (known battery life issues). Maybe the X Phone will give them the needed expertise while integrating software to hardware.

I've had the opportunity to play with both Z and ZL for around 1 week and I got approx a days use out of them both. In a normal situation I'm confident I could have got 25-30 hours if turning on STAMINA and not just playing with it.
