You can delete file manually but I would recommend "battery calibration" from Market.

Download and install app, fully charge battery and open app (don't unplug your charger).

Press "calibrate" button and restart (don't unplug your charger).

When your device boot, unplug charger and don't charge your battery again until power drops below 15% (you don't have to wait 0%- 10-15% is O.K)

And that's it.

Usually, battery calibration is recommended to use when you switch ROM or upgrade your ROM.

Because, sometimes, battery stats file keeps wrong data and you are using only 50,60,70% of your battery.

One more thing.

Charge your battery when you still have 20-25% - we are all using Lithium batteries and there's no need to wait 0%.

Lithium batteries doesn't like to be fully discharged so don't do that. :)

I have XS - one year old and battery is excellent - like it was new.

I spent many hours and talked with many people to find out what is the best way to preserve battery capacity...
[Xperia Z1 General] XperiaS_Lt26i:
every battery calibration apps requires root permissions right?
[Xperia Z1 General] funky0308:
Yeap...it needs to delete system file.
[Xperia Z1 General] [Fenix]:
This with the latest firmware (no root) :)

(about 3 hours and 20 minutes screen on)

I really like battery on Z1

I have brightness around 70-80% and for today this is the result.

Always get 5-5.5h of screen time :thumbup:
[Xperia Z1 General] mieshco:
Well for me it lasted 2 days... almost 48 hours - but I was barely using it... As you can see the handset was in the airplane mode overnight and from time to time I was using it - which is: wake from standby, make a call; wake, enable wi-fi, download something; wake enable mobile data, download something.

With auto backlight disabled, all power optimization stuff enabled, no 3g (2g only) - 0.5h of usage wasted 10% of juice...

After first (initial charging) it lasted for about 4h - wi fi was constantly on, downloading whatever was stored with associated google account

After second (overnight charge - which is the one in the screenshot) and being on airplane mode most of the time (with less than 3h of screen time and 1h of talk time) - it lasted 2 days.

Even my old 1400mAh battery in Desire is better than that, but still - it doesn't run quad core

P.S. making screenshots in a tough case is a pain in the a$$

I've had my Z1 for about a week now. I charged it straight out of the box to 100% and I normally let it run down to about 5-10% before I put it on charge. I'm running the. 534 build and rooted via Vroot. Keeping in mind I've come from an Xperia S which use to drink battery like a dehydrated camel, the battery on the Z1 blows it out the water. I have my screen on 50% brightness and today I've mainly been using my phone for whatsapping, listening to Deezer and twitter..I'm getting about 11hours on 50% batt...impressed to say the least.

Sorry, correction. Im consistently only getting 4 hrs of screen time.

Can I ask,

What firmware are you using?

What's your brightness setting on?

What do you usually do on your phone, does it require apps to run in the background?

Thanks!

I haven't a screen shot of it, but was only at 50% after 2 days of use, (I wouldn't say it was heavy, but it was fair enough usage....tethering quite a bit, Bluetooth on all day, a few short calls, wifi switched on after work till the next morning, a few games, etc. By far this is the best phone I've had in terms of battery life for a number of years.

oh, and i'm using krabappel2548's Stock 14.1.G.2.257 deodexed, tweaked, zipaligned, flashable Rom.

I do however regularly shut down all unneeded apps
[Xperia Z1 General] funky0308:
If you are using your phone as a phone (lots of calls) don't worry - it's normal to have shorter battery life.

That's absolutely normal...

If you are using your device as a multimedia device - it'll last longer ;)

I'm satisfied with my battery but I don't care that much.

When it need power I charge it and won't bother gor that.

I really use my device and it's in my hand all the time (I'm sure I'm not the only one) so....who cares for battery life when we have such a great device...

(I was kidding, of course, but it's true - right?) ;)
[Xperia Z1 General] malek777:
I think its the other way around. If you use your phone as a phone your battery will last much longer but if you use it for.browsing, watching videos and playing games it will certainly drain fast.

And for your comment on who cares about battery? Everyone! Including sony.
[Xperia Z1 General] marc_ecko28:
I agree..

When you use your phone for calls its stay much longer.

Z1 is on top when it comes to talk time.

Ofcourse battery life is important...

Loving the battery life on this phone. Yesterday fpor example, few hours of MP3 listening, 1.5 hours of video playback (both via Bluetooth) general email, web browsing. Got home from work after 10 hours and had 41% left and it was telling me I had 9 hours remaining - simply stunning. Only think turned off is NFC and I have force GPU rendering on.

Since last ROM-Update batt life is incredible fantastic. Today I started with my routine morning session (emails, google+, newspaper reading etc) and then I went on sightseeing trip through Dubai with offline maps constantly on and taking approx. 100 photos in different modes and 30 mins of vids), screen 100% (strong sun here in Dubai :) )

Came back to the hotel with 45% batt left after 9 hrs.....

Never ever had such a good smartphone
[Xperia Z1 General] wernerzero:
Really good battery on mine...

Must say that the battery life has surprised me on this phone...

With normal use, for me that is making calls, Facebooking, emailing, taking pics(lots) and vids, tweeting etc., I got over 40hrs with 44% left on Friday to Saturday, had to charge before my kids soccer game,so I don't know how long it would have lasted.

Only got it charged to 65% before we had to leave for the game. At the game I took some pictures and recorded over an hour of video, before running out of memory (no SD-card yet) and then I had 30% of battery left. :good:

I have GPS on all the time, all services, like fb, email, twitter, playstore updates and stuff, auto-syncing in the background.

I do use Wireless Minder and my screen brightness is on 25% (which is more than enough for me, still brighter than it was on XS/25%).

Only have one homescreen, I have Sidebar and Simifolder instead of more screens.

Impressed!!!

[Xperia Z1 General] Jiyeon90:
After 1 hour of browsing the web on 3G I had 88% left, then it only lost 3% after 9 hours of standby time despite having lots of apps running in the background. If I had greenify I would be able to get even longer battery life.

With moderate use I'm impressed =)
[Xperia Z1 General] ryan25012003:
Not too impressed with the battery. Really depends on screen usage though. Mine only lasts for about 9-10 hours of moderate use so it's not gonna get you through the night but I always have a portable charger with me so that's really a non issue. Still, the Lumia 920's battery life is hard to compare with this (which lasts me around 15-16 hours.)

I use STAMINA MOD.

Still....this is, comparing Xperia S, Xperia U or Nexus 7, extremely good...

10 hours, even on standby and not even 1% down - without airplane MOD, surprised me as well...

But, that's the way it is, I really don't have time or interest to fool you around...

Every single time I have 5,5-6,5 screen time and 20-26h battery life (brightness on 70-80%, I don't want compromise, long battery life and gray screen because I'm using 20% brightness) and believe me - I'm using my phone :)

That's good to do when you are upgrading or changing ROM, because battery calibration will delete battery sys file and create new one.

And now something extra...

Even I don't have nobody in Sony factories - I have few very nice friends who have access to some informations we, "normal" peoples doesn't.

I got informations and I can confirm it that Sony messed something in new firmware with stamina mod and battery. (kernel issues)

So battery info doesn't show all apps that uses power and calculations aren't correct.

For example:

I got this battery life because I used my phone for one day, when I reached 20% I connected charger but I charged my phone only to 75% and when I unplugged charger - battery didn't restarted informations and device connected to calculate time like I never charged my phone...

Sony knows for battery problems and it will be fixed in next update, maybe we will have to wait next big update (4.4) but it will be fixed soon ;)

[MENTION=4816245]funky0308[/MENTION] your battery stats didn't reset because it only happens when you charge over 90% and unplug (it's in every android device I believe)
[Xperia Z1 General] funky0308:
No mate, it's not.

It is until you charge but as soon as you disconnect charger, no matter how long you have charged it - it must restart time.

Also, sometimes STAMINA MOD shows wrong data.

It shows you'll have 10 hours with STAMINA on and 16 hours (or more) with STAMINA off - and that's not possible.

You are wrong mate.... Phone MUST be fully charged or restarted for the Battery Stats to be reset (on most/all of Android Devices)..

I'm using S3, S4, Z1 and all of them have the same thing, not fully charged = stats continue.. I had crazy SOT times on S3 when charged partially (up to 90-95%) few times in row... :p

BTW, You are right about Stamina as it gets messed up after partial charging, same here, I had ~1d12h - Stamina OFF, and ONLY ~20h with Stamina ON but it went back to normal after full charge.. ;)
[Xperia Z1 General] funky0308:
Well...On my Xperia S and Xperia U you could charge 1% and it will restart all statistics.

I'm not saying there's no chance that some phone have this - but that shouldn't happened, that what I'm trying to say...

That's error on kernel if that happens - why battery calculations if it doesn't show correct?

As I said, I know for that but that shouldn't be like that.

And what I have heard - that will be fixed like on XS.

I don't have contact in Sony but I have few friends that are working on very first development stage and they get firmwares for testing before they go out ;)
