[Xperia Z Q&A, Help & Troubleshooting] jf1972:
I got two Xperia Z(me and my wife) last week and can't believe the poor battery performance on it. I unplug the phone at 8:30 in the morning and have activated Stamina Mode with Whatsapp and Wechat being the only app that is on standby. I have turned on Wifi at home and no Bluetooth. I would have Bluetooth turned on while I am driving. It takes me about 50 mins to drive back to work. Once at work, it connects to the Wifi again. While in the office it would be about 10 mins for calls, 30 mins light surfing on the internet and maybe 5-7 pictures with camera. By around 3:30, I am left with 38%. It is even worse for my wife as she text a lot and does a lot of phone calls . She was using the iPhone 5 before and now she is requesting to go back to it. It doesn't even last her 7 hours:rolleyes:.

I have the Galaxy Note 2(N7102) and did the same test with about the same usage. I would still have 68% left by 3:30pm.

I have talked to one of my good friend as he owns a cellphone store in Mongkok, Hong Kong. The Japanese version of the Z is better in battery performance. My friend has access to the Japanese and International versions. So he did a test on both of them. Both phones had the same settings and was used with about the same usage. It turns out the international versions did drain faster. He had to charge the battery at around 7pm. The Japanese version didn't need any charging until 12am. I am guessing it might have to do with the firmware. Let's hope there will be a firmware upgrade soon to fix or improve the battery performance.

I have always like the designs from Sony. The Z for sure is one hell of a nice design!!

AW: Xperia Z battery life

Listening to music with screen off? Audio_out wakelock and mediaserver activity.

Touch vibrations and sounds, dialer vibrations and sounds, lockscreen vibration and sounds as well as keyboard cibration and sounds turned on? Audio_out and mediaserver activity. Disable them all.

Note 2 has weaker SoC and 130% the XZ's battery. Seems logical this far.

Also keep in mind, during the first couple days up to maybe a week Android is constantly optimizing and caching stuff. Battery will be very off during this time. And yes, it's an annoying fact but it's here, so wait for it to be over until more reliable readouts start to come in.

Re: Xperia Z battery life

Also consider the battery might still need calibration. My Nexus 4 rapidly depleted to 11% early on, then stuck there for about an hour before slowly going down. Thought it was never going to turn off!

Over time things can get better simply by reporting a higher charge with more confidence.

Guys, you should try the Sony Update Service software - it helped me.

In the beginning I got 20hrs. on average and Stamina was not working, also I had that fast discharging with the phone not entering the Deep Sleep power state. All is fixed now when I have just re-flashed the stock ROM. (May be the Stock ROM downloaded through the Sony Update Service is somehow modified and not the same version I had on the phone initially).

PS (the screenshot). The screen time below is around an hour with 3g always on, location activated WiFi, screen brightness set 50% with adapt to conditions on. Talked time - 30 minutes, few SMS, 20 minutes of browsing on 3g,

It's normal you won't get great results in the beginning. Have some patience for the first week, and post the results then :) .

I remember , in the beginning with XS i was getting ~2.30h max of screen time . Later on , situation was much better ...

After reading this comment today, i think XZ is fine battery wise . I still don't get how it managed only 5.30h of movie playbach on GSMarena, when a HTC Butterfly with identical hardware managed 3H MORE . There has to be some sort of glitch in ROM, or we can try installing HTC player :cyclops: . Anyway , getting my Z tomorrow,so i will look into that

Re: Xperia Z battery life

This was my first day using the Xperia z. Used it for a while then left it overnight and used it in the morning again till it died. Screen brightnesswas around the mid point. Stamina mode on with whatsapp and facebook on. Mobile data off but WiFi on for the duration of screen on ttime. Turned it off at night. GPS off.

And then second day. MOBILE data on. Stamina mode on with the two apps again. WiFi and gps off. A few phone calls. I don't understand what media server does?
[Xperia Z Q&A, Help & Troubleshooting] TeeJayEss:
Mediaserver is the background process which scans your media - music, photos, videos - and extracts EXIF information, ID3 tags, thumbnails, etc, and adds it all to the libraries. Once it's finished scanning and processing everything, it shouldn't need to run much in the future, unless you add a load of new media.

It litterally serves you with media. Use the search if you want to know more.

Re: Xperia Z battery life

I think a lot of people are comparing it to a Galaxy Note 2, which gets phenomenal battery life (I would know!). My Note 2 consistently gets about 6-7 hours of screen time and will usually go about 24 hours between charges, and this is with LTE. Based on what I've seen and read, I would expect the Xperia Z to get about 4-4.5 hours of screen time on a mobile network while being off the charger for 15 hours. This is what I surmised from the data I've seen. There is nothing wrong with that battery life. I think people may have expected too much. In my experience with a Nexus 4, the s4 pro chipset wasn't particularly efficient when it came to battery sipping. If the Z gets released with Canadian LTE bands I would seriously consider getting one.

Hi, guys!

I just bought Xperia Z a day ago.

But, something drains my battery extremely fast.

- STAMNIA mode is turned on

But, take a look at a screenshot attached?

I have not been use the Facebook at all, maybe did logging in, that's all.
[Xperia Z Q&A, Help & Troubleshooting] CaFFeiNe666:
i agree with you, you can't compare a

2300mah with 5" fullhd

with 3300 with 5,5" hd, little larger screen, much less pixel, much more battery

note2 is also much bigger than z, it's another kind of phone... (and you would also see to things like navigating white pages etc, wich have much more influence on battery for example)

xperia z is a big phone, but not a phablet... it's just quite bigger than my razr for example... note 2 is MUCH bigger then my razr :P

i could achieve in my second day (sorry i haven't screens) 3.47 hours of screentime on a 16/17 hourse total...

this with probably battery optimizations coming with 4.2.2 (a friend of mine with nexus 4 had almost a 50% gain updating to 4.2.2) i think is an excellent result for a fullhd phone... (and i'm on third charge today... so battery is going to give her maximum performance in these days)

p.s.

have you noticed, the REALLY GOOD call time? probably is one of the best in this... i made some calls about 10 minutes each one (3 or 4) i've lost something like 4% battery...

looking at gsmarena tests it goes near note2 with a 50% bigger battery...

always said that motorola and ericsson (sony) phone modules are far away than korean ones...

same with bluetooth 2 hours of music play, i've lost something like 8% battery... (headset doesn't support 4.0 low energy bluetooth, standard 2.1)

battery???

heres my xperince about the xperia Z battery. since im using it now for 2 weeks this is what i noticed

2 days xperia z can survive with one charge but with 3G off wifi connected. moderate use of calling chatting on whatsapp, viewing pictures and little gaming. brightness is 40%. i noticed before i go to sleep battery is 70% and i woke up after 6 hours still 70%. stamina mode is turned OFF!!!!

1 day survival with playing heavy games but maybe around 15 minutes interval coz im at work hehehe 3g off wifi off.... with taking pictures moderately. calls and sms.

charge 2x per day! yes it happened to me but i did an hour long gaming with fulll volumes, wifi on, few downloading of apps, viewing videos and browsing. i noticed that browsing consumes lot of battery. well volume is not that really high compared to my xperia S... here i charged my phone at night 100% then wake up still 100% the i go work and my boss is not there so ive got plenty of time playing my new xperia after 5 hours working i mean playing at work i still have 40% remmaining but i charged it at home coz i have 4 hours break... then again i willgo to work then i will charge again the phone at around 10pm...

[Xperia Z Q&A, Help & Troubleshooting] bucho2004:
For everyone who is getting bad battery results, I think I found a solution, or at least for me.

No matter what I did, I could not get on screen time longer than 3 hours, I mostly browse the web, and I can tell you the battery would disappear right infront of my eyes,

I realised however when I watch youtube app or anything else for that matter. the battery would drain alot slower. Could it be chrome? Why was my phone getting so hot when iam only browsing? Why is chrome occasionally yet what feels like constantly stuttering and freezing, as if it's losing wifi signal?

Well I decided to shop around reviews for alternative best android browsers, and seen dolphin browser in top five on almost all review websites. Downloaded it, and have been using it. Not only is it better looking with some nice ui and features, broswing has become buttery smooth just like jelly bean should be, zero stuttering or glitchy freesing. And my xperia z is no longer a finger radiator, so much cooler than when using chrome, what the f****? How is this possible? Any else had these proboems with chrome?

AND THE MAJOR CHANGE IS, I AM CURRENTLY ON 3 HOURS AND 10 MINS WITH JUST ON SCREEN TIME AND STILL HAVE 39% BATTERY LIFE LEFT.

I cant tell you how relieved I feel, my only gripe and hope with the xperia z was to be able to get 4 or just over 4 hours of on screen display battery life. Something that I know it can achieve now. When you mix that up with the superior OFFSCREEN/STANDBY battery time. I will definetley get a VERY GOOD battery life out of my xperia z.

Ps saw the samsung conference, so glad I chose sony, and I hope but doubt that the excellent htc one and the xperia z give the galaxy s4 a run for its money

[Xperia Z Q&A, Help & Troubleshooting] waveloom:
In my opinion, there is nothing horribly wrong with the battery of this phone but i think that there are a few issues to arrange to get better battery performance as long firmware is not yet full optimized, from this point of view:

1) this phone HAS incorrect battery calibration on firmware 350 so, it is conditional to format the battery prior first use, following Sony guideline well printed on the first film over the screen ..anyway you can format it anytime, turning on all network services and screen off, and let phone to turn off itself due to battery exaustion, THEN a full, continued charge to 100%, possibly with phone on and all network services and screen off.

2) Particular attention must be given to notification services of network apps, still the terminal mediaserver isnt fully optimized to use low cpu time on all of them, in first line facebook notification services.

3) particular attention must be given to apps that, in the actual firmware, tend to use excess of cpu time and bandwidth, first and not last, the system browser. Other apps can be identified keeping under control the backside heat of the terminal.

4) Useless to say that screen intensity and repeated vibration, the only mechanical part of phones, affect the battery noticeably...so auto brightness, quick screen idle and touch vibration off, reduce consumes of at least 10%

With this few attentions, the battery should full stand 4 days in occasional conversation, 2 days in conversation and casual browsing and email checkup, 1 day with intense network data usage or 6 hours of continued ininterrupted screen + network use.
