Is advisable yes, but root your phone with towelroot, download xposed+ bootmanager/adaway/ xprivacy, download greenify and wakelock detector, and lastly download " disable service" to disable within googleplayservices the locationsservices and maybe, if u dont use, the wearables services. My phone overnight in say 7-8 hours only 1% batteryloss , meaning it doesnt consume battery anymore when not used. Thats what u want i think ? cheers.

Btw in Kitkat battery drain Fix thread here at xda in Xperiaz forum is exactly what to disable to get optimum battery life ?

Try clearing cache and dalvik cache.. Use Ondemand governor even if u are on Stock kernel.. Also u may wanna avoid your hands touching the space below the camera.. XZ has always heated a lot and its safe until it reaches 90 degrees.. But 80 is almost same and u may wanna check for battery's health once..

[Xperia Z Q&A, Help & Troubleshooting] Hider141:
From what I know you have 2 options: either you buy a new back panel (because it comes with the double sided adhesive tape applied), or you search for a double sided adhesive tape that's exactly the same width and thickness as the one that's currently applied on the device and replace the old one.

But imho replacing the back-panel is the best option to be as sure as possible that water wouldn't enter because of defective adhesive tape placement.

P.S.: don't forget to be extremely careful not to overheat the battery inside the device when you'll open the back-panel, because it might explode.

The easiest way is to install wakelock detector. From there, all you have to do is to long press the item which causes the most number of wakelocks then google it. XDA links then will provide the reasons and ways to minimize if not disable completely the app/s which cause/s the wakelocks.

Battery Problem

Hey Guys, Its a life saver i found this thread.

My Xperia Z battery drains really quickly, so i removed most bloatware and disabled a lot of apps which i wont use, I removed updates from google play services because that was the main culprit, apart from disabling location services and making the brightness lowest i also am not using any widgets. Despite all this, when I charge with a standard 1 Amp charger, it takes about 4-5 hours to charge completely from 10-100 percent, i find this very disappointing. If i use the phone while its charging thwn it doesnt charge at all, sometimes level even goes down . Any advice on how to increase battery life, even stamina mode is on and Wifi is switched off most of the time, Im planning to get a 1.5 Amp charger to atleast be able to charge it faster

Fist of all you might take a look here: http://xdaforums.com/xperia-z/general/battery-life-how-to-to-7-hours-screen-t2382712

And you might try Greenify and Amplify and a more powerfull charger isn't needed. The phone takes that power it "needs". That the % go down is possible while gaming something.

I've got a strange question, i have had my z since they were first released and the other day i accidentally let the battery drain to just 5percent, so i placed it in its genuine sony charging dock and it kept rebooting for a while then appeared to start charging. Anyway about an hour later i took it from its dock and it was turned off and red hot to the point where it was almost too hot to hold. I have since left it for a day to cool down and can only get it to charge to fifteen percent in three hours of charge time, it would only boot to system bootanimation so i flashed totally stock fw and still it only makes it to bootanimation and dies, either way i think the battery has cooked and taken out the board with it?

Totally agree with this.

But every Xperia Z user can change to bigger battery (need somewhat basic soldering skill). You just need the flex cable battery, solder it to alternative battery of your own choosing. Be reminded though, the alternative battery cannot exceed 6.2cm x 6.5 cm x 0.5 mm dimension, and have to use 3.7 V.

How long have you been using the devices? If you have used them for over 1.5-2 years, and/or extensively, you may experience battery capacity deterioration. I have an xperia ZL.

The quality of battery used in both of these devices is questionable. You Can not rely on them for long term usage. The only solution i feel is to change the battery.

Well i assumed you are on stock rom. This is the general behaviour of battery of this device(xperia Z and ZL) i have noted on xda and some of my friends' devices. The thing is, the battery is NOT very trustworthy for long term usage. I'm just talking about hardware-side issues. You may feel the particular issue due to software issues too.

Now, the backlight stops working after the phone hits about 80%~ What I mean is, in the right light you can see that the screen is still on and functioning, but the backlight is just off...

any ideas?

[Xperia Z Q&A, Help & Troubleshooting] control freak:
You actually cannot deep discharge the battery if you don't tamper with it physically. There's a battery management system (BMS) chip onboard the battery itself which monitors battery voltage, temperature, and current. It won't let you discharge it so much that you cause damage to the battery.

It sounds as if your BMS is faulty. Unfortunately, if that's the case, you will have to replace the battery.

I'll suggest you Monitor the voltage and temperature using an app, such as ampere. It may help you to find out at what voltage or temperature the issue happens.
[Xperia Z Q&A, Help & Troubleshooting] OptimusCrack:
Hmm ok, I DID buy it used :/

So, I downloaded an app.

4.20v and the battery percentage says 97%

I plugged it in, the backlight went off. Great... it *usually* starts acting up around 80%, but its not uncommon to just quit at any time.

I unplug it and plug it back in a few times, finally it works when plugged in. I unplug it, and the voltage immediately drops to 3.97, and after a minute it jumps to 4.05 and again to 4.06v...

I should note that after this happened the very first time my brightness slider is ruined - when I change the brightness to the lowest setting it actually goes so low that it basically is unusable, which is very weird. Adaptive brightness is off, when I turn it on the screen goes very dark but somewhat useable.

Edit: Oh yeah, another strange thing is that sometimes the brightness just slowly goes lower and lower and lower and lower, with adaptive brightness still turned off, it'll do that until the backlight is off. This is happening right this second, over the past five minutes the brightness is almost completely gone, and it started at full brightness. 97% to 93% in the last 5 minutes, voltage is still bouncing around 4.0v and 4.03v
