Having just wrapped up our full review of the Samsung Galaxy Fame, we’re ready to share with you the results of our extensive battery performance test.

The Fame is the latest budget-range offering from Samsung, featuring a specs sheet that is far from impressive, but an Android Jelly Bean build that should hopefully result in increased performance from the 1300 mAh battery compared to last years’ Gingerbread devices. Let’s take a look. Read more »

The Samsung I9505 Galaxy S4, the Snapdragon 600 one, got a software update and while we felt like a new battery test was in order. A lot has changed since we released our first test and we were curious to find out how it has affected the smartphone’s power autonomy.

After the update, the battery life of the phone did improve overall. Here are the new results. Read more »

The Sony Xperia SP recently underwent our rigorous review process, and now we’ve got some battery result numbers to show you as well.

In many ways the “younger brother” of the new Xperia Z and ZL flagship duo, the Sony Xperia SP features the same Adreno 320 GPU as its older siblings, but without a 1080p screen to suck up extra battery life. Let’s see how it does. Read more »

The Sony Xperia ZL went through our battery tests and we’ve got all sorts of interesting numbers to share with you.

The smartphone has a similar battery to its Xperia Z sibling – the 2370mAh capacity of the Xperia ZL unit is just 40 mAh more than the waterproof flagship offers. Yet, Sony has rated the Xperia ZL to last a tad shorter than the Xperia Z for both stand-by and talk time and as we found out there are in fact some differences in real-life performance..

Having finalized our review of the Sony Xperia E, we’re ready to show you are battery test results from the single-SIM member of the Sony Xperia E family.

The Xperia E features virtually the same hardware as its dual-SIM counterpart – a 3.5-inch HVGA display, a 1 GHz single-core CPU, and a 1530 mAh battery. It does, however, run on Android 4.1 Jelly Bean and doesn’t have the extra SIM card to drain it. Read more »

The Nokia Lumia 520 is the cheapest smartphone of the Lumia range in existence and Nokia dubs it as the “The more fun smartphone”. But for how long can the “fun” last? Our extensive battery test comes into play to answer this very question.

For the money, the Lumia 520 isn’t a badly spec’d phone. It is built around a 4″ display and features a 1GHz dual-core Krait processor with Adreno 305 graphics on Snapdragon S4 Plus platform (MSM8227). Read more »

The Nokia Lumia 720 is the thinnest Lumia yet at 9mm, but it’s tied with the Lumia 920 for biggest battery in the lineup at 2,000mAh. The Qualcomm MSM8227 chipset is very efficient though as we already saw with the Lumia 620, which only had a 1,300mAh battery.

Will that make the Nokia Lumia 720 is the WP8 battery endurance champ? Read more »

Now that we finished with our HTC One review, we took our time to give you the detailed breakdown of the smartphone’s battery stress tests.

The HTC One is powered by a 2300 mAh Li-Po battery unit that handles the latest quad-core Snapdragon 600 chipset. So, how did the HTC One do? Here we go. Read more »

The Samsung Galaxy S4 is about the same size and weight as the Galaxy S III, except that the new model is slightly thinner. Even so, the battery capacity has increased by 500mAh to a nicely sounding 2,600mAh total.

Still, that battery has to feed four Krait 300 cores and a bigger screen with over twice the number of pixels. Let’s see how the 2013 flagship from Samsung compares to the one from 2012. Before we continue, we should make it clear that we’re using the I9505 for this test, that’s the Snapdragon 600 chipset and not the Exynos 5 Octa. Read more »

The LG Optimus G Pro brings several upgrades over the regular Optimus G, including a big 3,140mAh battery, but also a new screen and updated chipset. Let’s find out if the increase in battery capacity offsets the higher power demands of the screen, which is both bigger and higher res.

Before we go on, we’d like to note that our Optimus G Pro review unit (which came from Korea) has a spare battery and a battery charger/phone stand in the box. The international version might not have these goodies. Read more »

We already gave you our Samsung Galaxy Grand Duos review, but now it’s time to examine the battery life of the smartphone in great detail. You already know the final score, but let’s see how the different parts of the dual-SIM phone’s performance stand in comparison..

With a 2100mAh battery and a modest WVGA resolution you would always expect the Samsung Galaxy Grand to do well even if has a large 5″ screen to power and dual-stand-by to cater for. Read more »

Sony Xperia Z was announced back at CES in January and its popularity grows bigger by the day. We have already had the Sony Xperia Z for quite a while in our office and its in-depth review is over here but once the MWC wrapped up we were also able to complete its battery test.

The smartphone has a large 2330 mAh battery to rely on, but the quad-core Krait CPU and the 5″ 1080p display are known to consume quite a lot of power. The fact that the battery isn’t user-replaceable puts even more pressure on the Xperia Z to do well here, and we were as curious as you are to find out if that’s actually the case. Read more »

We approached the Nokia Lumia 620 battery test with mixed feelings. Windows Phones had hardly topped our charts so far and the meager 1300mAh battery of the Lumia 620 didn’t bode well. Still, we had certain hopes for it as its screen is not that big and the dual-core CPU is clocked only at 1Ghz.

Battery tests are time-consuming affairs and we’ve had several of those piling up. The Lumia 620 review has been published for a while now, but it’s only now that we are able to publish its detailed battery performance test. Jump after the break to get the full account. Read more »

The Asus Padfone 2 was announced just prior to the 1080p boom of 2013 but still has qualities everyone loves and yearns for in a smartphone – capacious 720p screen, potent quad-core processor, pixel-rich camera, Android Jelly Bean, etc.

And coupled with a slate it’s a really hard to beat combo, price-wise. But does its battery have the chops to last for more than a day – find out in the breakdown after the break. Read more »

The Samsung Galaxy Xcover 2 is one of the few smartphones with IP67 rating – it combines simple durability and advanced functions, so it needs to prove its endurance both when trekking in the wilderness, but also when enjoying modern conveniences like browsing the web.

A 1,700mAh battery is on the low side of what we would have imagined for a phone that’s likely to spend a lot of time away from an electricity socket, but let’s see if the Xcover 2 can counter the limited capacity with efficiency. Read more »
