I dont know about you guys but my SXZ easily cam reach 16-18 hours of battery life per day and my screen on time is on avg 4 hours. This is with data on 100% of the time and i think for the avg user plenty.

I usually get 40% juice left after i get home from work and of cos like everyone i charge it before i go to sleep

I agree with this entirely. It is ridiculous to own a mobile with all these technological advances but cannot last the day if we use them. I am an ardent fan of the Sony XZ BUT I am also a realist and the battery life is abysmal even when its in Stamina settings. It may well be the one thing that ends my days with this mobile. Problem is I have heard the S4 and certainly the HTC One are one and the same?

I would not like to return to my S3 but it is a truly incredible mobile and the difference between the S3 and S4 are negligible in real world use.
I Wont purchase the S$ as its to much like the S3 and in a new phone I think we all enjoy something new. The HTC One is a definite no no due to the signal strength problem here where I live. I am waiting for the next big gun to come along and see what that offers. It is a pain having to calculate how much use we may use the XZ or find ourselves with a dead phone. Charging every night is a must even for an average user and I don't use the XZ to play these battery consuming games either!

Without a revolution in battery design I think we have reached a ceiling with mobile 'uber phones'. I guess it was inevitable given our demands.

Could be. Of what use is a mobile with all the bells and whistles if it cannot function due to zero power? NOT saying the XZ is any different to the other top three but even I am getting mighty tired of monitoring every move I make on the Sony or find it dead! Some users cant even get half a day from it? Now that does make it rather difficult to defend. It IS a problem that needs addressing if any future technical developments are to evolve.

Regards.
Agreed! TBH whether we choose the HTC One, XZ, S4 or another FHD flagship smartphone, we're all going to have battery life problems. Mobile technology and it's needs for power consumption has developed at a much rapid pace and battery technology simply hasn't been able keep up! Furthermore, with all the tech, new features and how much of our daily lives are connected through a smartphone, its very hard to not burn out the battery by the late afternoon if you're a moderate to heavy user. IMO no matter which model we choose, if its the latest tech and has a FHD display, it's going to face battery performance issues sooner or later (I say this considering that all the tech and features are on and used and not having to resort to a setup that skimps on battery). The Note 2 is probably the only smartphone I have had that I could go a full day and do whatever I needed without having to worry about the battery dying. Since going to 5" FHD models, I realised that unless it had a 3500+mah battery, I would need to charge it in the late afternoon on a heavy day's use or carry an external/extra battery if I'm not near a charge port. IMO unless there's a revolution coming soon with battery technology, we'll need to accept carrying that extra battery to save our smartphones asses before the end of the day. If I'm out all day, I alway keep my 9000mah Samsung external battery with me.

I think one of the main contributions to this is the obsession of 'thinness' by reviewers and other media. Imagine how much more battery life you would have if the phone was 1mm thicker and that thickness was all battery. I'd gladly take that trade-off.

I would happily accept another 2mm in thickness on my smartphone for more battery storage!

Me too. It's strange that after so many years battery technology still remains the same (slow charging, low capacity). As if battery companies don't even care. If only we could charge those damn gadgets within seconds, battery life would be less important.

No one invest in battery, battery is the first thing need innovation to better performance now than any others part in phone.
Actually, batteries didn't really change in what, like 15 years ? Those really tine optimizations are nothing compared to what we need... so I totally agree, we need to provide more power, not only reduce our power needs.

BTW. Why does so many of XZ photos posted in comparisons are blurry and unfocused ? What's wrong with your cameras guys ? Mine takes very sharp photos, not like the one with orange - and it has nothing to do with compression, they're simply out of focus. Not suggesting anything, just honestly curious.

I also agree but then we would have the reviewers harping on not just about the thinness but the weight! Don't forget these reviewers expect a modern mobile to weigh no more than a sheet of paper.
Add to that the next generation are looking at 2.4Ghz CPU's and 4GB RAM. Already we have pixel density that only a hawk can appreciate its well past what the human eye can define 441PPI is more than enough not to mention bendy glass!

I love technology but......

The situation is all rather absurd isn't it!

The point of focus for all shots on the tangerine was right on the top at the green stem part. They were more or less macro shots cos the distance was very close. That's why the rest of the frame was blurred. The S4 did prove to be sharper in detail. The focus on the colgate mouth wash was on the word plax, again these were macro hence the blurred background. I took the shots under natural lighting and also with LED lights on to test both camera's metering and white balance capabilities and obviously the S4 came out on top. I'll be getting my Z back tomorrow and then i can do a more comprehensive comparison.

From what i have understood about battery tech previously, i honestly believe that there are companies that have spent a lot of time and money on development of battery technologies. However, due to costs related & other issues to commercialising it and the costs to be bourne by the end users, some of these technologies just haven't been able to reach the market. One of the major japanese companies have been working on a very dense battery tech that holds more charge and can be charged to 80% in about 10 mins. Whether we'll see this come to us consumers is not known yet but we definitely need something like this to keep up with the mobile tech!

Its due to amoled screen they use.. Sony is tft.. Try same photo viewing on s4 and z. Even if photo r same they look diff in each phone.. Thats the screen difference.. Im satisfies with sonys dsplay anyway.. Not a samsung fan here.:D

Is it okay to keep ur XZ charging overnight? Doesnt this overcharge the battery and overheats it and reduces battery life? Or does it have an ic which is auto off charging once it reaches 100%? Want honest answers.

I have always charged my smartphones overnight and never noticed heating issues or battery life deterioration. Lithium battery technology should allow for charging anytime and at any charge level. Generally the battery life cycle is good for at least 2 to 3 years or around 1000 full charge cycles, by then we would have changed to a new phone anyway. As for whether there's a cut off IC i'm not sure about that.

Someone with a background in electronics will know, but surely once battery is charged, current can no longer flow, so overcharging or overheating will never happen:thumbup:

So, I got my Z back from the Sony service centre last night, I thought the speaker high/low volume issue was fixed but its still an issue. I now need to take it back to Sony again...but I'm going to request a replacement this time. Failing that, I'll return it to AMEX for a full refund as its still within the 90 day return period. This just means that I can't do more comparison on the camera and video capabilities between the 2 phones. I'm now 10 days with the S4 and I can honestly say theres a lot to be liked about it but there are negatives as well. Anyway, my intention was to compare both phones thoroughly during daily use and decide on which works better for me and to keep after 2 weeks. So, basically I will be wrapping up the original thread with my conclusion by the weekend.

Thanks to all of you for reading and supporting this thread!

PS. The Sony rep told me that there will be 2 updates this month for the Z, one next week and one nearer the end of the month. She didn't say if it was going to be 4.2 or not (I don't have high hopes on that) but hopefully these updates will bring fixes for some key issues and improve optimisation. BTW, this is referring to the C6603 model with the local Hong Kong firmware, so not sure if it applies to other models worldwide.

Seems the update would be in the camera app.. When u click camra few seconds to prompt,some devices not totally launching the app,so take reboots to success.. I think thats cud be in the update and to think theyll also put white blnce to it like the zl..(,in my pov)

the s4 has better hardware but the design really puts the idea of getting one out the window, I was always more interested in hardware than design but this time around I just really can't go with that, I gave the s1 away because I didnt like the shape, but loved the s2 and it served me very well till the s4 is out, it was a long wait to see what the s4 really looks like, and before it actually went on sell I decided to get the Z, for 3 reasons, first obviously the shape, looks just like the s3, for some reason I just don't like that round shape, second european version it uses Qualcomm APQ8064T Snapdragon 600 Quad-core 1.9 GHz Krait instead of Quad-core 1.6 GHz Cortex-A15 & quad-core 1.2 GHz Cortex-A7, the Z running at 1.5 for me is more than enough to run everything I play with, plays Real Racing 3 very well thats enough for me, might as well go with the Z, third the water resistant is handy. so far I'm very happy with it. if I had gotten the S4 I know for sure I will wipe and go custom before I even use it, which I did with the S2, the interface all look the same, and look similar to iOS, the screen indicator actually looks the same. but with the Z, all I did was updated the firmware and root it, done nothng else with it since, havent had any lag on anything so far. 20hours on battery with phone, wifi, data, camera, gaming, map, gps, text messages, facebook, web browsing mix usage, still at 41% interesting to see how the S4 holds the battery

battery is differnt from user to user but I read 3-4 hours screen on, I'll be lucky to get 3 with screen brightness less than 50% and Greenify on.

You prefer a washed out screen?
color only wash out when looking at an angle its not like its complete white when you look straight at it.

this is how you distinguish between a photographer eyes and the normal user or consumer eyes...photographer stay true to their color while consumer really like that saturation.
