Amazing piece of hardware
By Kev
I didn't buy my phone here, but I felt the need to leave a review about this device.

Sony has finally delivered a top tier phone. The look and feel are absolutely premium. I get the feeling that I am using a solid piece of hardware, unlike that glossy plastic feel and look you get in products from Samsung SGS line and the new iPhone 5C. The stock rom (Android 4.2.2) is the 1st stock I actually really enjoy using and don't feel the need to switch over to a custom rom. I really don't understand why this phone is not getting 5/5. Sony has put in a lot of effort into the design. With the ever so slightly edges at the corners. A real nice touch with the glass backing. They even went as far as putting in two holes in the bottom right corner to be used for a camera wrist strap. Such as one like this Nikon 25770 AN-CP19 Black Strap. There is a nice discreet LED notification light at the top middle of the phone. A small but well liked feature. It flashes white when you have a notification, flashes red when on low battery and stays orange when charging.

The screen is so nice. Out of the 5x3 inches of the phone the screen is 4.5x.2.5 inches. It looks right and when using it you really feel there is a really nice amount of screen real estate available to you. I am also glad they did not include and physical home button on the screen.

I haven't even got to the best part. The phone is waterproof and dustproof receiving certificate of military resistance IP58. How great is that? The phone has 16 GB of internal storage. Most people will never go over 10GB of data their phone. I don't understand why people try to point out it has low internal storage space in comparison to the Note 3 which has 32GB or 64GB and can take external microSD. Great for the Note 3! But, who really needs that much internal data on a phone? Try going on the cloud. If you need the extra space the phone can take up to 64GB microSD for the people who need to horde data. If you need to go that route I suggest getting a Class 10 64GB such as this SanDisk SDSDQUA-064G-U46A Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter

The phones response time is so quick and smooth. I'm not going to give you the specifics on the internals but there is some seriously good hardware in the phone. I ran AnTuTu Benchmark and got a rating of 34789. If you do not know what that means, the Z1 is amazing. To give you a comparison the Note 3 got a 33814, HTC One 25651 SGS S4 25161 Nexus 7 20438. As you can see the Z1 is beating the rest in the benchmark scores which basically means it has the superior internal components.

My only bad thing I have to say, is i'm afraid this lovely glass finish is going to get scratched so I had to get a very nice case for it and a screen protector. VSTN®Sony Xperia Z1 Honami L39H ultra-thin PC Case Cover (For Sony Xperia Z1 Honami L39H, Black)

If you are going to install the screen protector yourself I highly suggest getting some anti-static spray and apply it before installing the screen protector. Getting a spec or 2 of dust under the screen protector looks ugly. If you are going to be spending all this money on a phone, go the extra mile and buy the spray. ACL Staticide 530 General Purpose Topical Anti-Stat, 4 oz Trigger Sprayer Bottle

This phone is the international edition so it recieves many different GSM radio frequencies and can be used with just about any GSM mobile network across the world. Just don't forget if you want to use your Mobile network data you have to put in the providers Access Point Name (APN). This can be found in Settings > More > Mobile networks > Access Point Names.

You will also need to set up your MMS network if you want to receive or send mms (picture messages). Go to Settings > More... > Internet Settings. Hit Accept then Select your Service Provider. It will install Internet & MMS settings.

The phone takes only microsim and is fully LTE capable, which I have no problem using on Tmobile's USA network. If you have a normal sim card and can't get a microsim immediatly, you can make your sim into a microsim with this. QQ-Tech Nano Sim Card Cutter Mini /Standard & Micro to Nano Sim for iPhone 5 iPhone 4, 4S and other Phones + Metal Tray + 2 Sim Adapters + Sand Paper, All in One Pack (In Stock Ready to Ship) Though, I highly suggest to get your providers official microsim if possible.

If you are into rooting and installing custom roms, the phone is easy to root and to unlock the boot loader.

The camera is 20.7MP. It takes good pictures during day time and has good flash for indoors, but the focus seems to "stutter". Nothing that can't be fixed, they just need to release a better software update to it. It is just an annoyance at most. The pictures I have taken so far have been really good. I haven't used it to take night time pictures yet, so I can't comment on that. There is a nice little added feature of a physical camera button on the bottom right. It makes it feel again as if you where taken pictures with a camera. It is a welcomed feature.

If you are worried about breaking the small watertight flaps for the phone when charging it, you can get the Sony charging station for it. Sony DK31 Cradle or Patuoxun Magnetic Charger Charging Dock Station Cradle For Sony Xperia Z1 L39h /Xperia Z Ultra XL39h Black

Overall this phone is an A+.

Excellent phone that now replaces my iPhone
By MajesticRa
I think it is best or one of the top phones on market right now. I was fascinated by Xperia Z which my best friend obtained this summer. So I bought this Z1 and absolutely happy with it (had iPhone before).

1. 4G.
I have T-mobile and 4g works with it. The phone has pretty good connection most of the time network is accessible.

2. Sturdy.
The phone was severely fallen to concrete floor for 2 times. No cracks or any scratches on the glass sides. Small scratches on a flank side but no dents or deformations. I'm happy it is so sturdy (or I'm so lucky)))

2. Camera.
It takes good looking pictures even in tough exposition conditions like sunsets, background illumination etc. Can't say it is much better than iPhone 5 camera but I find it generally better. Night pictures have high iso noise. Focus has been improved after the last update.

3. USB.
I really enjoy the fact that if I plug the phone to pc by common micro-usb cable it may be detected as a simple storage. No stupid iTunes (You can install sony app from the phone if so you WANT. But you don't have to. At all).

4. Sync, Charge and Watertight flaps.
I sync the phone by wireless and use dock station Sony DK31 Cradle to charge it. So I don't open watertight flaps at all.

5. Water.
I haven't taken any photos under water yet but I did call the phone in spa bath and got the phone under rain. Also once it was in sand. No problems. Since that I like the idea that I can receive a call if I'm interrupted in a shower))

6. Software.
I've found much of the Sony software useless. Can't say it is bad nor good I just get used to other apps. Android has a giant apps market with a lot of alternatives.

7. Hardware.
The hardware is pretty fast. I haven't found any slow running or laggy application or game yet.

8. Battery.
As all slim smartphones with high-end hardware you have to put the phone on charger often. It takes 1 day or less to discharge in normal mode. 2.5 - 3 days in stamina mode. 1.5 - 2 days in normal mode with battery saving soft installed. I'm sure it will worsen when the battery exhausted in 1-2 years.

9. Screen.
Pretty sharp. I've found it good but not exceptional. I mean it is good, bright and sharp for reading, surfing, gaming. But pictures on my old iPhone are looking the same good as on calibrated LCD. Pictures on Z1 looks worse than on PC. I know the description is very subjective, but that is what I can say. Video works fine.

10. As a player.
I REALLY like that I can download any player from market and listen possibly ANY file format. WITHOUT iTunes. After 3 years of using iDevices I couldn't get used to it. I mean, managing my library by folders, putting music to phone by simple copying what I need and WHERE I need is much much more convenient for me than using iTunes.

11. Sound quality.
I compared Z1 output with V90-HPA headphone preamp using Sure 535 earphones. Surprisingly the difference is not so big at all. Z1 sounds brighter while V90 sounds softer and deeper. But there is NO such a gap like between laptop internal sound card and V90. I would be really impressed if the phone sounded better. But... I'm still impressed with the comparison.

FINALLY...
I'm happy I have it. I would recommend it among all the other devices of the same class that are currently on the market.

You can even use it as a phone
By Frans Hoynck van Papendrecht
I do a lot of photography for my work, using a Canon dslr and two Nikon compacts. For two weeks now I also use my new Xperia Z1, that turns out to be good enough for a lot of shooting and that is very easy to carry arround.
It is the first camera I ever had that you can even use as a phone :-)

Those are genuine second-generation eneloop cells - as far as I can tell
By NLee the Engineer
I have done extensive testing on the original eneloop rechargeable batteries since early 2007, shortly after they were introduced in the US. I have also tested the blue second-generation eneloop cells from the Costco eneloop package back in 2010. But this is the first time I have seen second-gen eneloop in white wrappings being sold in the US. With so much talk about counterfeit eneloop going around, I was understandably cautious when I purchased those SANYO NEW 1500 eneloop 8 Pack AA Ni-MH Pre-Charged Rechargeable Batteries.

I tested four of those cells, using my old La Crosse BC-900 Battery Charger.
- Right out of the package, their average remaining charge is 1568mAh, or nearly 80% of the rated capacity of 2000mAh. The spread is also very small, from 1558 to 1577mAh. This proves that they are indeed low-self-discharge type. (Date code on my cells says "11-01", or Jan 2011)
- After one recharge/discharge cycle, their average capacity improved to 2115mAh
- After two more recharge/discharge cycles, their average capacity leveled off at 2133mAh, or more than 6% higher than the rated capacity.

The above results are very consistent with what I have previously observed, while testing second-gen eneloop cells in the Costco package. Therefore I'm convinced that those are indeed genuine second-gen Sanyo eneloop cells. (See the scans I uploaded to Customer Images section, if you need to distinguish between old and new eneloop cells)

On the other hand, currently the prices of those new eneloop cells are about 25-50% higher than that of the original eneloop cells. So one may question: do the new eneloop cells offer sufficient improvement over the old, to justify the price different? Let's compare the following factors:

- Cycle Life: The 2nd-gen eneloop claims to "recharge up to 1500 cycles", while the original only claims 1000 cycles. This 50% improvement looks great on paper, but note that if you recharge your eneloop cells twice every week, it will take 10 years to reach 1000 cycles. So in real life, most average users will never notice the difference.

- Self-Discharge Rate: The new eneloop cells claim to "maintain 75% charge after 3 years", while the original only claims "80% after 2 years". Again, in real life most people will never notice the difference.

- Capacity: First-gen eneloop AA cells have "Typ 2000mAh, Min 1900mAh" printed on them, while 2nd-gen eneloop AA cells only say "Min 1900mAh". But in fact they have the same capacity rating of 2000mAh (typical) according to official Sanyo web site. My measured capacity numbers are actually around 2100mAh for both versions.

BOTTOM LINE:
Both the new and old eneloop cells are excellent products. You can safely mix and match them in any application, and probably nobody can tell the difference in the next 10 years. But in case you can't decide which version is a better value... Just flip a coin and pick one - you can't lose either way!

[Update on July 31, 2011]
Long term self-discharge data: I have tested a pair of new eneloop AA cells after 104 days sitting on the shelf (the batteries, not me). The average remaining charge is 88.7%. This charge-retention rate is slightly better than that of the original eneloop, but the difference is within margin of error for my experiment.

[Update on May 8, 2012]
Nowadays the 2nd-gen eneloop cells are generally priced lower than the original. So you should definitely get the newer version.

[Update on Apr 7, 2013]
Long-term self-discharge rate update: I just tested a set of 2nd-gen eneloop AA cells after two years in storage. They retained 1685mAh, or 84% of rated capacity. This is no difference from the claimed charge retention rate of 3rd-gen enellop (which says 85% after two years). See my following review on 3rd-gen eneloop:

Sanyo eneloop FAQ
By NLee the Engineer
I have been using Sanyo eneloop low-self-discharge NiMH batteries since beginning of 2007, and I'm completely satisfied with them. One thing I noticed is that newcomers to the rechargeable battery arena often have similar questions/confusions about eneloop. So here is my list of eneloop Frequently Asked Questions. This list is work in progress.

[Q1] My Sanyo eneloop AA batteries say '1900mAh' on them. Are they counterfeits?
[A] All eneloop AA cells (both original and second-gen versions) are rated for "Typ 2000mAh, Min 1900mAh" according to Sanyo. The confusing part is that 2nd-gen eneloop AA cell only has "Min 1900mAh" printed on it, even though the actual measured capacity is close to 2100mAh.
Simialrily, eneloop AAA cells are rated for "Typ 800mAh, Min 750mAh".

[Q2] Date code on my new eneloop cells says '10 01' (Jan 2010). Should I exchange them for newer batteries?
[A] Relax! Unlike ordinary NiMH cells, Sanyo eneloop are still perfectly good even after 5 years in storage. Once you recharge them, they will return to 100% capacity again.

[Q3] What is the difference between 'Pre-Charged', 'Hybrid', 'Stay-Charged', 'Active Charged', 'Ready to Use' and 'Ready to Go'?
[A] Those are all marketing terms for Low-Self-Discharge (LSD) NiMH batteries. Sanyo first used the term 'Pre-Charged' for Sanyo eneloop back in 2006. Rayovac used 'Hybrid', and so on.

[Q4] I just received some new eneloop batteries. Do I need to recharge them before use?
[A] You can use them right out of the package. However, eneloop cells are only charge up to ~75% when they left factory. So you can use a Smart charger to 'top-off' their charges. Do NOT do this with a Dumb charger because it will badly over-charge them.

[Q5] I thought I have to drain my batteries completely before recharging them?
[A] This is only necessary if you are using a timer-based dumb charger. With a smart charger, you can top-off your batteries anytime.

[Q6] Can I use other brands of chargers to recharge Sanyo eneloop batteries?
[A] Sanyo eneloop batteries can be recharged using any good-quality Smart charger designed for NiMH cells. But for longer battery lifespan, avoid ultra-fast (15- or 30-minute) chargers and Dumb (overnight) slow chargers

[Q7] What is the difference between 'Smart' and 'Dumb' chargers?
[A] A Smart charger monitors the voltage profile of each cell individually during charging, and stops when a charge-termination signal (negative delta-Voltage) is detected. This is the only way to avoid over-charging. A Dumb charge relies on safety timer to stop charging, or has no termination mechanism at all. This usually results in over-charging which is bad for battery lifespan.

[Q8] Should I stick to the Sanyo MQN06 charger packaged with most Sanyo packages?
[A] The MQN06 is semi-smart but has two issues: it charges in pairs (monitors the combined voltage of two cells), and the charging current is only 300mA. That means it take about 7 hour to recharge a pair of eneloop AA cells. A better choice is the Sony Cycle Energy BCG34HLD.
[ Note: Charge time (hour) = Capacity (mAh) / Current (mA) ]

[Q9] What is the best charging speed for Sanyo eneloop?
[A] Choose a charger that gives you charge time between 2-5 hours. That means charging current of 500-1000mA for AA, 200-500mA for AAA.

[Q10] Isn't it true the best charging speed for NiMH and LSD-NiMH battery is the slowest?
[A] That is only true when using a dumb charger which blindly charges for 12-15 hours, so the current has to be below 0.1C (200mA for a 2000mAh cell) to avoid over-heating. For a smart charger, the current needs to be at least 0.2C to ensure proper termination.

[Q11] I always keep a set of ordinary NiMH batteries in the charger to keep them freshly charged. So why do I need LSD cells?
[A] You don't need to do that with LSD cells. Just charge up a spare set ahead of time and keep them in your drawer. Swap them in whenever needed, just as how you use disposable cells.

[Q12] Why should I buy those 2000mAh Sanyo eneloop instead of ordinary NiMH batteries that are rated 2500mAh or higher?
[A] All rechargeable NiMH AA cells rated 2500mAh or higher are susceptible to Rapid-self-discharge problem. Beware of off-brand batteries that claim '2900mAh' or higher. Most of them can't even deliver 2000mAh.

[Q13] Can I use eneloop in places with extremely hot weather?
[A] As a rule of thumb, every 10 degree C rise in temperature causes the battery's self-discharge rate to double. So although your eneloop cells can still function correctly, their shelf life will be reduced at high ambient temperature.

[Q14] Should I store unused eneloop batteries in the refrigerator to extend their shelf life?
[A] For ordinary NiMH cells, storing them in lower temperature greatly reduces their self-discharge rate so you can get longer shelf life. For eneloop cells it is hardly worth the trouble, because they can be stored for years at room temperature.

[Q15] Can I use eneloop batteries in cordless phones?
[A] Yes - as long as your phones (such as Panasonic DECT 6.0 cordless phones) are using individual AAA cells, instead of battery packs with special connectors.

[Q16] Do rechargeable batteries only go bad after they meet the number of charging cycles, or their lifespan is limited by time also?
[A] Capacity of a NiMH cell gradually deteriorates with number of discharge cycles. The 'lifespan' claimed by manufacturer is the number of deep-discharge cycles before capacity drops to 50%. This is done under tightly controlled test conditions, so in real life your result may vary.

[Q17] When rechargeable batteries go bad, do they also spill chemicals (like alkaline cells) or just won't hold a charge?
[A] Good-quality NiMH cells do not spill electrolyte as they gradually deteriorate. The only chance this can happen is when they are (a) severely over-charged at a high current, or (b) severely over-discharged, or (c) exposed to extreme heat.

[Q18] My baby swing calls for 4 D sized batteries. Do eneloop D spacers work well?
[A] You can use those in a pinch, but expect to replace/recharge your AA cells a lot more frequently than before. This is because the energy stored in an alkaline D cell is about 7-10 times greater than that in eneloop AA cell. See my following review for other options: SANYO Eneloop Spacer Packs with 2 AA with 2 D-Size Spacers

[Q19] My La Crosse BC-700 Battery Charger reports some eneloop batteries as 'null'. Are they defective?
[A] If a battery is over-discharged and its voltage drops below 0.5V, the La Crosse charger cannot detect it and so the display says 'null'. Charge your 'null' battery in a dumb charger for a few minutes, then the La Crosse charger will recognize it.

[Q20] I read on Wikipedia that there is an Eneloop 3rd generation battery (HR-4UTGB.) Are they worth getting over second generation?
[A] Panasonic (who bought Sanyo in 2009) claims that lifespan of 3rd-gen eneloop cells has been upgraded from 1500 to 1800 cycles. But keep in mind that even if you recharge your cells twice every week, it will take you nearly 15 years to use up 1500 cycles from your 2nd-gen eneloop cells.

[Q21] Are the new AmazonBasics Pre-Charged Rechargeable Batteries just rebranded 1st-gen eneloop cells?
[A] Not exactly. According to their mechanical features, they are most likely SECOND-gen eneloop cells. See my review for details: http://www.amazon.com/review/RLX50IR99K7PL/

[Q22] How do the new Duracell pre-charged Batteries ('2400mAh', 'Long Life Ion Core') compare to Sanyo eneloop or XX cells?
[A] Based on my testing, I believe the Duracell 'ion core' AA cells are actually rebranded Sanyo XX AA cells, while the Duracell AAA cells are rebranded 2nd-gen eneloop AAA.

Second-gen eneloop better than the first - by a hair
By NLee the Engineer
This package (Sanyo SEC-HR4U4BPN) contains four second-generation eneloop AAA rechargeable batteries. I have tested those cells using my old La Crosse BC-900 Advanced Battery Charger. Here are my findings:
- Right out of the package, the average remaining charge is 640mAh, or 80% of the rated capacity (800mAh)
- After the first recharge cycle, the average capacity increased to 839mAh.
- After two more recharge/discharge cycles, the average capacity leveled off at 843mAh, or 5% higher than rated capacity.

The above is very consistent with the results I obtained last year, while testing 2nd-gen eneloop AAA cells from the Costco package. Therefore I have no doubt that those batteries are genuine. Date code embossed on them says "10-12", which means Dec 2010 (see my upload in the "Customer Images" section, if you need to know where to find the date code).

According to Sanyo press releases, those 2nd-generation eneloop cells offer several benefits over the original eneloop:
- Can be recharged "up to 1500 cycles" (vs. "1000 cycles" for the original)
- Can hold "75% charge after 3 years" (vs. "80% after 2 years")
- Works down to -20 degree C (vs. -10 degree C)

In real life, however, it is nearly impossible for the average user to experience those benefits. Note the even if you recharge your cells twice every week, it will take nearly ten years to reach 1000 cycles. Furthermore, the advertised self-discharge rates for new and old eneloop cells are actually the same during first two years.

As to the capacity: original eneloop AAA cells have "Typ. 800mAh, Min. 750mAh" printed on them. The new eneloop AAA cells only say "Min. 750mAh". This has created confusions for some people, who thought the new version has lower capacity. But according to Sanyo web site, capacity of the new AAA is also 800mAh typical. My own test results, however, have shown that measured capacity of the original eneloop is around 4% higher than rated, whereas capacity of the new eneloop is about 5% higher than rated. Again, the difference is so small that most users will never notice it.

BOTTOM LINE:
Second-generation eneloop cells do offer some improvements over the original, but the actual benefit is very hard to verify in real life. In my case, the price I paid for this new eneloop AAA package is only 10% higher than that of the old one, so I consider it a good deal. If the price difference is much greater, then you have to decide whether it is worthwhile to pay extra for those perceived benefits.

[Update on May 31, 2011]
Prices for the new eneloop AAA have came down further during the past month, so now it is an even better deal. But just in case you are looking for greater bargains, you may want to consider the GP ReCkyo Pre-Charged AAA cells. They are priced lower than Sanyo eneloop, and have slightly higher capacity (rated 850mAh, measured 880mAh).

[Update on July 31, 2011]
Long term self-discharge data: I have tested a pair of new eneloop AAA cells after 92 days sitting on the shelf (the batteries, not me). The average remaining charge is 89.4%. This charge-retention rate is slightly better than that of the original eneloop, but the difference is within margin of error for my experiment.

[Update on July 3, 2012]
Amazon again combined multiple Sanyo eneloop products (many AA/AAA packages and different chargers) into a single product page. This makes it very difficult for people to find reviews for a specific product. In particular, my "Sanyo eneloop FAQ" was previously attached to the product page of Sanyo eneloop 4 Pack AA, but now it can only be found by following this link:
