All bow to the new endurance king: Sony Xperia Z3 scores a record battery life for its category

All bow to the new endurance king: Sony Xperia Z3 scores a record battery life for its category
We are not going to mince words here - Sony is the current king of battery life when it comes to brand-name smartphones. We did our grueling battery benchmark on the Xperia Z3 over the weekend, and it broke all records in its respective category, just as we suspected it would do, given Sony's consistent performance in that department this year.

The phone lasted for nearly nine and a half hours of screen-on time when we ran our tasking battery benchmark, putting it comfortably ahead of any other flagship big-screen phone or phablet we've tested at the moment. 

As mentioned, this is more than any other flagship we've measured so far - phone or phablet - and even more than the Ascend Mate7, which comes equipped with a whopping 4100 mAh juicer, while the Z3 has an "only" 3100 mAh piece in a 7.3mm thin waterproof body. 

The Z3 battery endurance is also better than the one of the Z2, which already has a great battery life, so kudos to Sony here - it managed to squeeze much more life out of a tad smaller battery, compared to the Z2, and make a truly "two-day battery". The charging time, on the other hand, is much longer than the average, at close to four hours with the paltry stock 850 mA charger. 

If you think that what Sony did is by accident, then a simple look at our top ten endurance champs will tell you that this is not the case. Sony phones are currently occupying six of the top ten slots in our battery benchmark ranking, and these range from low-ends, like the Xperia C, through midrangers like the slim T3, all the way to the Xperia Z3 flagship. The "culprit" must be Sony's displays, which might not be the best out there when it comes to color representation and viewing angles, but are apparently using an extremely frugal technology, and screens are the pesky components with the highest battery consumption in our smartphones, so kudos to Sony here.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

PA should update their review rating to reflect this awesome news. Z3 Compact should be ~ 9.3

Indeed, I can not trust the impartiality of a site's reviews if they give the same score to inferior (but over over-hyped) fruit devices.

I ordered a Z2 as soon as it was released in the US, and I was über exited. The phone arrived and I was thrilled. Then it happened. My phone fell of the sofa onto my carpet (about 2 feet) when I picked it up it had powered off. I charged but to no avail. I took it to the SONY store and customer service couldn't do anything. They kept asking "would you like to buy another one?" I decided to get an iPhone 6. Best Phone Ever Period . It is amazing in every way. I am now grateful my Z2 broke. It enlightened me. Thank You SONY for making such crappy products.

I would take the Z3 Compact with its amazing battery life any day over any other "Flagship" phone simply for the battery life! What good is it to have the best CPU, the best GPU and a QHD screen if you can only use it for an hour at a time?

Exactly. My other want/need is reception. I might have to take a closer look at Sony for my next phone.

Sony Xperia Z3 Compact 14h 44 min. Please level this kind of battery life as "Outstanding".

I can agree. In comparison especially with Windows Phones, which are very poor regarding battery life and other features, this is really awesome result. Sony and Samsung are the best.

Where is the 1320 and the 1520? Can't see any of those in the comparisons!

Yes. If only. Please sony, please make a 6.5" z3 ultra. I want the z3 compact as my daily driver and a z3 ultra to use as a tablet.

70. InspectorGadget80 unregistered

That was holding me back. Either the Z1 with flash or Z Ultra largest phone in the world.

Its not the largest if you include tablets with phone functionality

I was thinking of buying a new larger phone, really loving xperia z ultra. But the lack of flash kept me from choising it. Damn Sony, you've missed a new customer! I'd better switch to the new Huawei Mate 7.

I'm in love with my one m8 battery life, but the z3 is putting it on show. I'll wait for m9 and see what happens.

Their claims were spot on, it seems. 2 days without Stamina mode. 3 days with Stamina. 1 week with Ultra Stamina. Now trim down on your midrange budget and make like a lone SP successor for 2015 or something.
