To lessen the load on battery, root your phone.
download root app delete and disable preloaded apps your not . install greenify and hibernate apps that you dont use when exited. just dont greenify your launcher or any 3rd party app that need constant updating, like facebook or twitter or viber.
that's it, save tons of battery time

Anonymous, 02 Jun 2014Thanks for the tips, but what do you mEan on battery back up? Battery back-up of xperia z is better than xperia zl. Also, there are overheating concerns in xperia zl.
Anonymous, 02 Jun 2014which one is good and why? xperia z or zl?both device are actually almost similar unless we talk about being waterproof or dustproof. If you need your phone to be waterproof or dustproof the go for xperia z. otherwise go for xperia zl. moreover, complaints about battery back-up is more in xperia zl.
customer, 01 Jun 2014No update has come for xperia zl in india ao how u have updated sony give fake info
why do you judge like that?
you can update your xperia ZL with any XperiaZL rom, if you worried about the base-band you can uncheck that when flashing, so you will retain that but have an updated phone
about the battery issue, disable ALL sync options, ALL of them, also disable "backup" with google.
the battery issue is due to a continuous syncing which means your phone is using the internet connection ALL the time.
also if don't use facebook, twitter, google+, then go to apps, force stop, clear data and disable everything facebook, twitter and google+ related (about 12 different apps), restart your phone (turn off and then on) and your phone should have no battery issues, it will also boot faster;
if it continues having battery drain, (do a backup using sony pc companion) then either do a factory reset, or use SUS (sony update service) to repair your software, after this, you should be ok, the annoying part, is, you will have to install everything again.

Since i have upgraded to 4.4.2... Battery doesn't last very long (compare to other version before) and when i turned off the screen and want it on immediatly, it takes some time to turn on...
Marcelo Karma, 29 May 2014My ZL is upgraded to KitKat and still normal, I think this problem is with your phone...Nothing wrong with my phone. it was running like a dream from the time I got last year till i updated to 4.2.2. Sine then a whole lot of issues. My phone doesn't even load the ring tone. That's how bad this update is. taking up lot of memory and draining the battery
ok guys updated to 4.4 but going back to 4.3
the update is actually clean, i don't use facebook, twitter, google+ or anything like that, since i am not rooted i disable all of them, also i disable the auto sync and the location is set to device only, when you do a clean install or a factory reset, right after you set your google account uncheck all the options you see, all those sync stuff, back up device.. etc, UN-CHECK them all, this way you will have a very long battery; to avoid the scrolling lag go to developer options and check force GPU, after this, reboot it, your phone will work very smooth.
then you can sync your contacts by taping the phone icon and select the google account option, you dont need to keep the phone syncing.
if you are a facebook user, then get the app from google play, also do this for twitter and so on.
this will avoid the services issue that drains battery in most cases
so why am i going back to 4.3?
firstly i use my phone for many things, ill try to name a few, of the most annoying in my case:
GPS apps cant access SD-card, this is really awful, yes, it can be fixed by rooting, but i am not rooted, also there has been reported issues using the "doomlord easyroot method" so, i am not rooting, which means no SD-card access for most apps, with gps this is a most, i have about 2 GB of maps, and i wont be filling the phone's internal smemory...
some photo apps cant access SD-card, if you need to record a travel or want to record various videos you cant...
some unoptimized kitkat apps will get the phone very hot, i guess is how they use processing power and memory, i have 2 online game i could only play for 10 mins before the phone went to 42ºc.
some emulators had issues, ok the new full screen option is great, it hides the menu and status bar, on most apps, but some emulators became unplayable, recast doesn't even boot games, this was what really got me thinking going back to 4.3
no file browser will be able to write or edit stuff on your SD-card
and office apps will have issues handling SD-card data (once again this can be fixed by rooting)
so for me this is more than enough to go back to 4.3, until there is a safe and easy way to root and optimized emulators.
so if you only use your phone for communication, and "social networking" you will be fine, you may actually love the update
but if you use your SD-card a lot, and need to work around with files, and games on external storage, you wont enjoy it.
hope this helps everyone

Media taking up 60% of the battery power. Sony, what did you do updating to Kit Kat without testing. Killed my ZL. Please find a solution.
Ane 1 in india got the kitkat update for zl. When ita gnna arrive in india??
I think ZL is the best cell phone overall , except the battery drainage issue from the 1st day till & after Kit Kat.
The most weird thing is now that ; If I start charging it off the Wall outlet when the phone is ON, it either does not charge(shows as charging though !) , or completes charging in around 24 hours !!!!
In other words ; it consumes as same power than charging , just at standby !!!!!
However, if the phone is OFF , it fully charges in 1-2 hours.
I see that there are many cell addicts in this Forum, PLS HELP.
As full charge lasts half a day at minor usage!!!.
Thanks in advance.
