Mine seemed to be doing well, but as soon as it was connected to my car Parrot kit the consumption was ridiculous. Ended up taking mine back today and getting a black one.

The guy who runs the Three store where I live told me during the exchange that the North East of England has done less than 700 in all the Three stores, obviously he couldn't tell me how other independents, Phones 4 U and Carphone are doing but I have a feeling that this isn't doing as-well as Sony thought it may do.

I was also the 4th person to go back this week with some form of battery issue.

Hope fully the updates that are and will be coming out will help the phone, otherwise it looks like Sony will have missed the boat and HTC, Samsung and Apple will capitalize.

Battery life seems great to me. The first few days I was worried as it seemed to drain quicker than my Xperia s.

After 10 hours on battery I am at60% battery remaining, 2.10 hours screen on time, mainly web browsing with opera mini, played a few minutes of Lemmings.

Stamina mode on, Screen brightness at almost Zero (still looks brighter than the XS at 20% IMO) with adaptive lighting on.

My xperia S would probably have been down to about 45% or worse - I usually got about 4 hours of screen on time during my normal day with the XS.

Android OS is taking up quite a lot of % too, so I hope that after Sony update to 4.2.2 battery life will be even better - but even if it remains the same I'm happy.

Yes its stamina, but its normal to have wakelocks from it as disabling/enabling stuff in background. If you have abnormal number of wakelocks, then something is stoping stamina in working propertly,but stuff under the "alarms" is more battery consuming , so check that for battery drains ..

Xperia™ Z C6602 Battery review!

Standby time is awesome, just awesome! Slept overnight with STAMINA™ mode with HSPA+ network on for about 12 hours (yes, i sleep a lot) and didn't lose a single charge, it was constant at 97%

(My HTC wildfire drains a lot of battery in comparison almost 15%, i use almost same apps so I thought it was worth a mention )

However, LCD draws a lot of battery power even at the minimum brightness browsing net and downloading for 30 min can lead to a drain of 7-10% in battery with Bravia engine turned off!

If you listen to music with the screen off only 1-2% of power is lost in an hour! Pretty good if you ask me! :)

However battery gets too heated if you use it extensively while charging and cuts off power at about 44.5 Celsius to cool down. I just submerge it in a bucket of water for a minute to cool it down! :D

I assure you, nothing is draining your battery. Over 8:15h you had 7:30h deep sleep, 45 mins awake time of which 38 mins are screentime. Leaves 10 uncovered minutes of wakelocks, which is sensational. And you lose 1.4% per hour on average, which is, simply put, sensational.

Serious problem with Xperia Z battery

Very disappointed. Just got an xperia z and I am afraid there is a serious problem with this phone regarding battery life which may or may not be specific to me.

Even in stamina mode with virtually no use/syncing it is dropping 3-4% per hour , with use it is about 1% per minute!

Battery checks report it as healthy.

Main usage is screen during active use which is draining the battery at an alarming rate. 0.5 % per minute on calls or internet from screen alone.

I think this is a software power management fault, maybe specific to my phone but my overall opinion is to avoid the Xperia Z as it smells systemic to me from the reports here. Worse still this could be the most power hungry screen known to mankind (even dimmed).

[Xperia Z Q&A, Help & Troubleshooting] TheNeighbor101:
Re: Xperia Z battery life

I know! I'm not so convinced with Sony's reputation of spasmodic battery of the Xperia series and they go with non-removable batteries.

Why would people keep worrying about battery life so much witht the XZ all the time just to get throught the day? 4 to 5 hours of screen time sounds not so much for me since I'm used to 6 hours+ of screen on with wifi/3G, bluetooth connected to BT stereo earset & smartwatch, synced with 8 accounts all the time, 2 hours of internet music, and can be downloading 1GB worth of torrents daily - and this goes on for at least 12 hours and up to 16 to 20 hours per battery charge for me. And I don't even have Juice Defender on.

Well, I think I can't expect those demands with the XZ's reported battery performances

Don't get me wrong, XZ users - I love the design and the fact that it's waterproofed. I wished Sony put in at least 3000mAh in this.

[Xperia Z Q&A, Help & Troubleshooting] thegregulator:
Re: Xperia Z battery life

Of course you're going to get that kind of battery life with the Note 2. The battery is roughly 1/3 bigger than the battery in the Xperia Z. By what you just described, the battery life you're expecting is about 1/3 better than what I'm getting on my Z. All in all, I think the Xperia does all right for power management. If you were expecting battery life similar to the Note 2 you either didn't read any reviews, or you're ignorant.

I turned Stamina off and my battery life has gotten much better. I'm in the middle of testing as of yet, so I can't give any figures yet, but the battery lasts considerably longer now. I get less than 1% per hour with very moderate use.

I had certain apps whitelisted in Stamina, such as email and calendar, so it couldn't turn data off completely. This, I believe, resulted in Stamina turning data on and off continuously when apps requested for it. This uses more battery than saves it.

I can only reason that if you whitelist any apps that sync automatically, then you are undermining the principle idea of Stamina mode, which is: "data off when screen off".

If you, like me, want to keep your apps synced, then you're probably better off switching Stamina off completely.
