Don't know if this has been posted already but recently Qualcomm released an app on the Google Playstore called BatteryGuru which is specific to their chipsets (S3, S4, S4 Pro, etc) that is supposed to improve battery life as it fixes a few small issues related to their hardware.

If you have the Xperia Z I suggest downloading this and trying it out.

More info below

[Xperia Z Q&A, Help & Troubleshooting] orenxda:
installed, this app doesn't say it optimizes pure processor behavior, but proposes to manage apps updates, and turn off wifi when you don't need it (based on location!) > if you stop location services (i don't use) it halts " battery saving features of the app"
[Xperia Z Q&A, Help & Troubleshooting] robogo1982:
Agreed, that info is just fine (and I presume it will improve once devs get their hands on the phone).

Re: Xperia Z battery life

Root the XZ, and install One Power Guard. It tweaks the CPU and kernel so efficiently with various modes you change depending on the load you need.

I use it to slow down the CPU speed by 400mhz and I find it extends my usage by 6 to 8 hours than just 12 hours of mere heavy use and full CPU. No lags.

I've seen it said that Sony batteries need to experience several charging cycles before they reach their true potential. Anyone finding that to be the case so far? Or I suppose the better question is has anyone had it long enough to find that to be the case yet?

Almost makes me wonder if review sites had the phone long enough to put it through those paces and see if the battery would improve after a while.
[Xperia Z Q&A, Help & Troubleshooting] hebbe:
let's wait and see how the battery behaves after a few charging cycles.

btw, stamina-mode is impressive. having it on standby for about 8 hours it just lost 1% of battery.

been using the phone for nearly 13 hours (8 nighttime), and about 2-3 hours of heavier usage (wifi, downloading, installing and testing some apps), i still got 78 % of battery. (50% brightness, no lte).

Wow. Am I the only one that thinks the battery life on this device is poor?

I'm seeing plenty 3 & 4 hour screen on times, that's seriously underwhelming, imo.

And as far as Stamina mode goes, what does it do that I can't? Seems to shut everything down, which any user can do on their own. It's more convenient sure, but it's not going to help me while I'm actually using my phone.

The sound & battery life on this device should have been improved.

Important thing is now MMC1_Detect is now seems fixed. After backup of sdcard I formatted it and put my files back in. I didnt use MTP mode I used normal MSC mode.

I am very suspicious about this MTP mode file transfers now.

Because instead of %7 now it is only %1.3

In 1 hour 12 mins it only waked for 57 secs. Which is much better than before.

I will continue testing after a charge session to see if it holds.

Edit: it is rising again it is now 4.4% :( bah.

It is now after 2 hours -> MMC detect is 6 minutes. :/

xperia Z's battery sucks

the phone was charged to 100% before I was playing duel card game for 35-40 minutes and the low battery notification appeared, i was surprised to see the battery level down to 27%, drained way too fast. I took my sister Htc One(2300 mAh battery compare to 2330 mAh on xperia Z), suprisingly its lasted for an hour and 15 minutes. Now, both phone's batteries are irreplaceable, nevertheless the HTC one using 1.7ghz quadcore compare to 1.5ghz on sony. I love the design and outlook of the xperia Z so much but i have to return it since i need a reliable battery cause im on my phone all day.

Nah I just use the HTC for comparison purpose. I mean even when I'm using for texting+listening to music, the battery reduces more than 40% after almost 2hrs, I can accept the HSPA+ speed, low wifi signal or grainy picture, but I would like the battery to last at least 6-8hrs with normal texting +listening to music

This kind of stuff is really a pain in the ass. Maybe some app is causig those scans. Try freezing couple of them, maybe you find out in the end which it is :). For a comparison, mine mmc1 consumption during 24h is somewhere between 5-10mins

[MENTION=309187]edit[/MENTION]

had some observation just now. Before i started writing this reply mmc1 was 6mins.While i was writing i opened solid explorer to read some text file. Now its 14mins. So, that one really depends on how much you usr media dependent apps

So, you should worry about mmc1 only if its active during the night for example, or while your away..

Well, I was planning to make a thread of my own - But here a thread exists. :)

I'm suffering from very Mediocre battery life, on 1.253 rooted, Stamina Mode always on with only 3 apps allowed (Whatsapp, Gmail, Sports Tracker).

Also using Greenify (App that hibernates other apps while the screen is off).

Screen is on 80%, Only Wi-fi is on most of the time (Sometimes not even that).

It seems like there's a very annoying Wakelock that I can't trace by some sort of System process... I've taken some screenshots - This is only at 80% battery, but it's very similar even with low battery (Very high percentage take by Android OS). Here are some Screenshots:

Android OS is using 53% for some reason.

Only 20 minutes of Screen time should not bring down the phone from 100% to 80% - Clearly something else is draining the battery.

Using an app called Wakelock Detector, it points to a process that's responsible for general wakelocking, doesn't help very much...

What do you think I should do? I've tried debloating the ROM, turning off Location services... This is frustrating...

[Xperia Z Q&A, Help & Troubleshooting] Aresmar:
I have only mmc1_detect wake lock now. Which I cant get rid of no matter what. I think it is a bug with 253 kernel. I will leave it as it is cause it doesnt drain much battery power. It is just silly to see Android OS take up %50 of battery tho.

I hope they fix it with new kernel. :S
[Xperia Z Q&A, Help & Troubleshooting] GodShapedHole:
Right after installing .253, I thought my battery life got SO much worse... but then I realized that it was actually WidgetLocker that was responsible for the drain (installed it a day before .253 arrived for me).

Now that I got rid of it, my battery is *almost* as good as it was before, with one weird exception: when I charge my phone to 100% overnight and reboot it, it goes down to between 95% and 97% immediately, with Media using up 75-78% of the drop. This has happened to me before every once in a while, on other phones as well, but if I previously charged it back to 100% and rebooted, I'd be at 100% - probably some sort of calibration issue. Now if I charge it to 100% and reboot, it will ALWAYS drop a bit immediately, no matter what I do.

Even with relatively (for me) heavy usage, I get through a whole work day plus getting a beer or going for sports with a comfortable percentage to spare when I get home; the XZ has never failed me in this regard, even if I don't charge it at work. My old Galaxy Nexus needed to be charged at work, or it broke down. So any complaints I have aren't really issues for me... but I know y'all understand that nagging feeling in your stomach when you just feel that something isn't working at 100%, even if it works absolutely well enough.

I have the phone and I can take mine of charge in the morning at 7am and run it through the whole day (using it for work mainly) and still rock around with at least 25% battery in the evening when I'm finished at work, 8pm. Stamina mode is on, 3G running, sometimes WiFi, NFC from time to time (passing on contact cards) and on breaks I watch films.

Screen is set to 65% and have a fair few widgets.

After all that, what are you doing on it for you to be charging not every 4 hours? On my holidays I relax from it and stamina mode truly shows off and can give me roughly a day and a half.
[Xperia Z Q&A, Help & Troubleshooting] GodShapedHole:
I think the only way to conclude that the battery on XZ is terrible is to play 3D games all day long and end up with a dead battery after 4 hours. But I don't know any other phones that would fare much better, except perhaps a Galaxy Note - less than half as many pixels to push, almost 30% more battery capacity to push them with. If you compare oranges to oranges, however, eh, the XZ is up there with all the other flagships.
