The Samsung I8530 Galaxy Beam is a fairly unique device with its built-in pico-projector. Samsung has put a big 2000mAh battery inside the smartphone, which is almost as big as the one on the Galaxy S III, and given that there’s only a dual-core processor and a smaller 4″ LCD to feed we expected it to fare quite well in our test.

We put the Galaxy Beam through our usual battery testing procedures and we are now ready to share our findings with you. Read more »

The Meizu MX 4-core is a revamped version of the ambitions MX smartphone, which challenged both the iPhone and its Android kin alike with a heavily customized OS. The MX 4-core, as the name suggests, uses a quad-core Exynos chipset from Samsung (like the one in the Galaxy S III) and also has a slightly bigger battery than its predecessor – 1700mAh vs. 1600mAh.

What other changes has Meizu done under the hood to improve battery life? The Chinese haven’t gone into specifics, but we saw improvement across the board. Read more »

We are all well aware by now that the combination of Qualcomm Snapdragon S3 chipset and LTE network connectivity do not bode well for the battery life of a smartphone. Throw in the Sony Xperia ion’s HD screen in the mix, and its easy to guess that the 1900mAh non-removable battery has a lot to deal with.

As always we took a look at the 3G talk time performance of the Sony Xperia ion first for AT&T. Read more »

LG Optimus Vu is almost a tablet, but it has voice calling functionality and qualifies for our full battery test. It’s a big device, so there’s room for a big battery but there’s also a big huge power-hungry screen to consider – let’s see how these two things balance each other out.

It’s a little disappointing to find out that the Optimus Vu has only a 2080mAh battery – even the 4X HD had a 2150 mAh juice pack. Read more »

The LG Optimus 4X HD uses NVIDIA’s Tegra 3 chipset, featuring a special power-saving CPU core which NVIDIA made a lot of noise about. Couple that with a large 2150mAh battery and the Optimus 4X HD should be more than simply adequate in terms of battery life, right?

The HTC One X has similar specs (Tegra 3, 4.7″ 720p LCD), but a smaller battery (1800mAh), so it didn’t quite top our charts even with the above-mentioned extra core. Read on to find out if the LG will do. Read more »

When we reviewed the Nokia 808 PureView a lot of our time was spent on the camera. Now that the review is done, we’ve had time to test out the battery – it’s a fine balance between Symbian’s low requirements and the relatively small 1400mAh battery.

The 808 PureView is far from the most compact phone around, so it’s natural to think that Nokia could have fit a bigger battery. But maybe they didn’t need to, find out after the jump. Read more »

We’ve had the Huawei Ascend P1 in our office long enough to run the battery tests. Since we couldn’t find official battery life numbers on Huawei’s website, this is our first look at how long the 1670mAh battery lasts.

The Ascend P1 performed more or less as we expected it to – with web browsing once again proving to be the bane of AMOLED screens. The other numbers are very good though. Read more »

The Samsung Galaxy Pocket is a budget offering from Samsung, which aims to scrape the bottom of the Android barrel by luring users into the smartphone game for cheap.

It packs a meager 2.8 inch screen of QVGA resolution, a QVGA camera, and no real power-hogging connectivity features to speak of, so the 1200 mAh battery, despite being on the rather small side, should be good enough to provide ample power. Our barrage of battery tests should certainly help us see how well it actually does. Read more »

The Sony Xperia P packs a special screen with WhiteMagic technology, which promises a lot of power-saving – up to 50% Sony says. But the other variable we need to consider here is the battery – and its meager 1305mAh capacity.

So, the screen may seem well suited to display web sites (which are predominantly white) with its white subpixels, but the battery is smaller than the one on a Samsung Galaxy S, which came out two years ago with a similarly-sized screen and a single core chipset. Read more »

Compared to its predecessor‘s 1500 mAh battery, the one found in the LG Optimus 3D Max P720 has received a rather modest 20 mAh bump in capacity. Interestingly enough, a year ago we would have considered a 1520 mAh battery as a large one by any standard. Today however, it appears downright insufficient, especially when there’s a 3D screen waiting to be powered.

As you have probably guessed by now, we approached the battery test of the LG Optimus 3D Max with a pinch of suspicion. Here goes the full breakdown. Read more »

In our review of the HTC Evo 4G LTE, we noted that the Sprint Wireless exclusive smartphone one ups its AT&T relative – the HTC One X, on a couple of instances. The bigger, 2000 mAh battery is one of the Evo features, which is certain to make the owners of its polycarbonate bodied relative jealous.

We already put the HTC One X for AT&T through its paces in our battery test, and came quite impressed with what we saw. Naturally, the expectations towards the Evo ran even higher, given its larger battery. Hit the break to find out how it did. Read more »

As most of you probably know by now, the HTC One X for AT&T packs a different chipset than its NVIDIA Tegra 3 rocking, global sibling. A Qualcomm made, Snapdragon S4 chipset with two CPU cores is the reason for the US available HTC One X’s LTE connectivity.

This means that testing out the battery life of the two HTC One X versions is the perfect showdown of the battery efficiency, which the latest and greatest Qualcomm and NVIDIA chipsets offer. Read on to find out which one came on top. Read more »

We’re done testing the battery endurance of the new Samsung flagship and we are ready to share the results with you. The I9300 Galaxy S III has a huge 2100 mAh battery, but its 4.8″ HD Super AMOLED still causes concern.

It was also interesting to see how the new-generation Exynos 4212 Quad chipset fared. It has no companion core to handle less demanding tasks, but all of its four Cortex-A9 cores are built on a 32nm process, so they should be pretty efficient. Read more »

The battery test of the Samsung Galaxy Y Duos S6102 is done – it took some time, but the Y Duos is quite different from most other phones we’ve tested, both because it’s a dual-SIM phone and because it’s a fairly low-end Android.

We couldn’t run the video battery test as our standard test videos just wouldn’t work and a lower-res video wouldn’t make for a fair comparison. We doubt many people will be interested in watching a movie on a 3.14″ QVGA screen anyway. Read more »

There is a general consensus by now, that LTE connectivity and long battery life don’t mesh well together. Therefore, we were a bit skeptical when we started testing the endurance of the HTC Titan II. After all, the smartphone has a fairly modest 1730mAh battery, which, not only needs to cover for the LTE radio, but also has a massive 4.7″ screen to light up.

We kicked things off with a look at the talk time of the imposing smartphone. Read more »
