The latest offering from Acer features a dual-core 1.5GHz Krait CPU, and pushes out an 4.3 inch HD display on Adreno 225 graphics.

It’s seems that this is quite a lot to ask from a 1460 mAh battery, but let’s if it’s up to the task. Read more »

The Nokia Lumia 820 is our first brush with the Finnish company’s next generation of Windows Phone handsets. It has a relatively small battery (1650mAh), smaller than even HTC’s Windows Phone 8X juice pack. And that one certainly didn’t impress us much with its battery life.

The Lumia 820 has a dual-core Krait processor running at 1.5GHz inside (like most other WP8 phones) so we don’t expect this to make any difference, but that 4.3” AMOLED screen probably will. Read more »

The HTC Droid DNA leads the charge of phones with super-sharp screens into the west – it has 5″ 1080p display with an amazing pixel density of 440ppi (the screen looked great when we handled the phone).

The demanding resolution is taken care by the powerful Snapdragon S4 Pro chipset with a quad-core Krait processor and the new Adreno 320, which is the best an Android phone can get at the moment. But is the 2,020mAh battery too small? Read more »

The Samsung Galaxy Premier is the latest in the line of Samsung droids to undergo out battery test gauntlet, and the dual-core 1.5 GHz device showed some great battery endurance – especially in regards to video playback.

Lets take a look at how this mini powerhouse performs in other areas as well, including talk time and web browsing. Read more »

The HTC One X+ is a quick update to the company’s flagship – they pumped up the Tegra 3 chipset to higher clock speeds, fitted a bigger battery to compensate and threw in some extra storage to sweeten the pot.

Now the question is whether the bigger batter and Jelly Bean are enough to offset the extra power usage from the overclocked chipset. Read more »

The HTC Desire X is fresh out of our review but there are still things to wrap up. The phone has a 1650mAh battery feeding its dual-core processor and 4″ screen. How does the battery last?

Well, we’ve concluded our full array of battery tests and the results await your inspection after the break. Read more »

Microsoft’s latest mobile OS is getting ready for prime time and the ailing HTC is marketing its Windows Phone 8X as the “signature” Windows Phone 8 handset. We already reviewed the 8X, now it’s time to see how long it lasts in our battery test.

The HTC 8X has an 1800mAh Li-Ion battery and a Qualcomm Snapdragon MSM8960 chipset – virtually the same specs as AT&T’s One X, expect for the smaller screen (4.3″ vs. 4.7″). Read more »

Dual-SIM phones are still relatively rare and usually limited to the low-end, but the Samsung Galaxy S Duos takes after the Galaxy S III mini in terms of looks (though not in terms of specs, unfortunately).

Dual-SIM phones are usually bought when there are no good plans available – ones that offer enough talk time, texts and data. So, how long can the S Duos last if you need the second SIM for even more talking? Read more »

The LG Optimus G is the first phone with the monster Snapdragon S4 Pro chipset that we’ve reviewed, so we’re very curios to see how battery efficient it is. Four powerful cores can be a blessing (get the job done quicker, go to sleep quicker) or a curse (burn more energy, even if the job takes less time than on slower cores).

So, which is it? The battery has 2100mAh capacity, which is exactly as much as the Samsung Galaxy S III and HTC One X+ have, so the Optimus G can’t rely on that to gain advantage. Read more »

We’ve just concluded our in-depth review of the Motorola RAZR i and its Intel Atom Medfield chipset inside and now it’s time to shine a light on its battery performance.

The Motorola RAZR i achieved some pretty good scores in all of our tests, but its talk time endurance was partucularly impressive. Read more »

HTC Dual-SIM Android smartphones aren’t something we come by every day, so when the HTC Desire V came by our office, we were eager to test how it’ll fare in our battery test. Especially since its main selling point is the ability to facilitate two SIM cards.

The HTC Desire V gets its juice from a standard for its kind 1650mAh Li-Ion battery, so you shouldn’t expect it to run circles around the heavyweight champions like the Samsung Galaxy Note II and the Motorola RAZR MAXX HD. Read more »

The Samsung Galaxy Note II is one of the most impressive droids out there and judging by our mailbox everyone was interested to know more about its its battery performance. Well, we are finally done with the tests, and we are now ready to share the results with you. The tests took a while to complete, for reasons you’ll see shortly.

The Galaxy Note II has a beefy 3100mAh battery – 1000mAh more than the battery in the Galaxy S III, but 200mAh less than Motorola’s RAZR MAXX battery. And there’s a large AMOLED screen and a quad-core processor to feed. Read more »

The Samsung I9300 Galaxy S III Jelly Bean update is finally seeding and we already got our office units updated. Our review of the 4.1 Jelly Bean and TouchWiz combo is already available and you can learn all there is to know about the updated Samsung flagship right here.

Meanwhile we finally competed our battery test on the Jelly Bean-powered Galaxy S III and we are ready to share the results with you. Read more »

The iPhone 5 has been the center of attention here at the GSMArena HQ for a few days now. We’re busy putting it through its paces and it’s time for us to reveal the detailed battery results and see how it does against the current crop of top smartphones.

Apple has implied that the iPhone 5 is bending the laws of physics and it turns out when it comes to the battery, that claim isn’t far from the truth. Read more »

The Xperia T is Sony’s first go at a Snapdragon S4-powered phone (not counting the Japan-only Xperia GX), and should give us an idea what to expect from the similarly spec’d Xperia TX and Xperia V.

The Sony Xperia T features a 1850mAh battery, which is one of the biggest we’ve seen in a Sony smartphone. Remember the 1305mAh batteries in a few fairly recent Xperias? Yeah, that wasn’t enough. Read more »
