Battery doesn't charge to 100%, it stops at 96-97%. It only shows 100% for cosmetic reasons. So nothing is wrong.

Battery life is pretty nice with new .253 firmware. It's at least the same like before updating, but now without debloating, greenifying and editing system files like hosts.
[Xperia Z Q&A, Help & Troubleshooting] sea2605:
Im very interested in updating to see wether the new fw and all the tweaks I applied will result in more screen on time.

My bootloader is already unlocked, current I'm on .434, rooted and use doomkernel v6. Is there already a way to update to the new fw, rooting it, NOT loosing my settings and data AND using the doomkernel? Couldnt find anything about that.
[Xperia Z Q&A, Help & Troubleshooting] dante501:
I am since 1 day 7 hours on battery with 28% left and a 46 % of screen time. I think that is quite good. Never had an android phone with that good battery life. I was happy to get like 12 hours or a little bit per day. This phone has the best so far.

Oh yeah, in this update i get much better battery calibration . Previously i could work 30min and still have 100%... now 2mins and percentage starts to fall easily

Anyone else finding that listening to music drains a lot of battery? Those who use their phone to listen to music regularly how much battery does it usually drain?

I've been playing music from my sd card through earphones for about an hour now. Battery has dropped about 15%. Mediaserver usage at 50 mins is 27% and com.sonyericsson.music at 18%.

Right now my screen on time is about 1hr 20min and that is 26%, less than mediaserver usage.

Mediaserver usage seems unusually high for me. Have not rebooted my phone so shouldn't be a media scanning issue...
[Xperia Z Q&A, Help & Troubleshooting] sriszone:
Does any one noted that after the firmware update to 253, battery drains quicker than ever...
[Xperia Z Q&A, Help & Troubleshooting] dante501:
Well when listening to Spotify it drains battery fast. Even so I downloaded the music so it isn't streaming it. On every single phone so far it drains battery fast.
[Xperia Z Q&A, Help & Troubleshooting] Ivan_Diego:
Well it depends :/ I only noticed huge drain rate between 100% and 94%, but after that it seems that overall battery life is better for on screen time...

That's my notice :/ I am still in calibration process of my battery after update, so I can't tell you for sure is it better or not :eek:

---------- Post added at 10:41 AM ---------- Previous post was at 10:29 AM ----------

Hmmm, hmmm... I don't know. In some cases it's batter, but in the other hand something else drains my battery, so I can't tell you exactly is it better or not :( My experience is that battery life is little bit improved from my old firmware .350.

For example Mediaserver usage at 1h 17m is 16% and com.sonyericsson.music at 10% and 56m. Screen is 1h 24m and 15%, Voice calls is 1h 10m and 15%.

Phone is running 1d 11h and it's on 39% of battery...

I hope this will help you :)
[Xperia Z Q&A, Help & Troubleshooting] wawyed:
I'm afraid not, with heavy use it will survive 4 hours maybe 5.
[Xperia Z Q&A, Help & Troubleshooting] Ivan_Diego:
Depending on what you think is heavy use... If you have everything turned on, sync, wi-fi, 3g or even 4g, brightness on relative high level, screen on for long time, and maybe if you are gamer, then definitely your battery will die very soon :)

Although, I didn't test it yet on heavy use.. :D

That's my battery life. But that's on Wifi over Mobile Data the battery isn't close to being that well.
[Xperia Z Q&A, Help & Troubleshooting] drsoran2:
Here's my battery life on the second full discharge after upgrading to .253 firmware. I think it's excellent. With the older firmware, I never had over 4 hours of screen on time over the same period of standby time. Now I have 4h 33min.

What I did during this time: facebook, browsing, e-mail, twitter, instagram, whats app, Temple run, some other apps, etc.

Sync was always off, phone on wifi whenever possible. Greenified some apps, frooze some Sony and other useless apps with Titanium Backup.

Note: This was WITHOUT using Stamina mode. Gonna try that next time and see how if affects battery life

Comparing it with my best ever run it's little worse, but i won't jump to conclusions as i have different battery calibration now.

Also, now I'm running slightly higher brighness level and have 2 email account on sync and WORKING what's app.

What's app is the main reason why i deleted greenify, cause i couldn't get it working properly, even after converting it to system app

What's the advantage of making them user apps?
[Xperia Z Q&A, Help & Troubleshooting] MafiaManV:
Greenify couldn't stop system apps from running so you have to convert them to user apps so it can handle them. There's no downside as far as i can tell, so i left them that way even after deleting greenify. Maybe it even helps stamina, who knows :)

Finally drained the battery and i can conclude greenify can get you further.

With greenify, i had exactly the same screen on time but with 19h more of standby time.

We know XZ is really good with standby consumption but thats a + for greenify.

Its - as i said earlier, killing wanted apps and services

Other thing i can notice is that Sony really improved Stamina functionality over older fw. I don't remember this kind of results earlier.

Next test will be by using different governor (interactive now), and maybe Stamina switched off, to see where that gets me :)

- plug charger / usb cable into phone, do not discharge it! otherwhise you will lose some capacity

- leave it for a while for a few hours until it fully charged

- do not drain off until at 0%

- do not need to calibrate, just few little charges would be more effectives

- you can charge when battery life will be under 20%

Re: Xperia Z battery life

Finally, the info on the 36% being used in 2 hours is useful. This gives some factors for calculation.

If the 2 hours of continuous heavy screen-on usage of the Xperia Z uses 36% of the battery charge, then therefore it can go about 5.55 hours continuously.

(2H/36%)x100%=5.55H

Of course you might not be continuously be using the screen on with that total amount but somehow you would be aware of this. This doesn't count it being on LTE or downloading torrents. Or not even with standby time yet.
