The Samsung Galaxy Alpha comes in two versions – one with Samsung’s brand new Exynos 5430 Octa chipset and one with the more common Snapdragon 801 chipset. Both have small 1,860mAh batteries. Small relative to the phone’s size, of course, 4.7″ phones typically have 2,000+ mAh batteries. The Galaxy Alpha is pretty slender though, just 6.7mm, which eats into the available volume for the battery.

Today we’re testing the Exynos version of the device. Read more »

The Sony Xperia T3′s battery life test is now complete and it’s time to share with you how it did. The phone is impressively thin at just 7mm, but thanks to its large stance, it houses a decent 2,500mAh battery.

Combine this with the Snapdragon 400 chipset, which has a solid record being mostly frugal, we can expect the phone’s draw on battery to be as optimized as possible. Additionally, Sony has integrated the Power Saver option into the Settings menu. It helps you extend the battery life by toggling Wi-Fi, GPS, Bluetooth screen brightness, auto sync and background data on and off automatically when the battery charge falls below a certain user-defined threshold.

The Samsung Galaxy S5 mini matches the looks of the big Galaxy S5 and even most of its features but opts for a smaller display, body and in turn smaller 2,100mAh battery.

The screen of the Galaxy S5 mini is 4.5″ against the 5.1″ of the Galaxy S5 and the resolution is more than two times lower at 720p. The chipset should also be less power-hungry so the 700mAh-less battery should do okay to match the 72 hour endurance rating of the bigger Galaxy S5. But there are a slew of minis to fight as well – let’s see how the Galaxy S5 mini did. Read more »

The HTC One (E8) sheds the weight of the aluminum unibody and drops the low-res UltraPixel camera in favor of a 13MP shooter. Neither of those affects battery life compared to the One (M8) and the battery capacity is still at 2,600mAh.

What could affect the battery endurance is the new chipset – the One (M8) we tested used a Qualcomm 8974AB while the One (E8) uses 8975AC. Read more »

The HTC Desire 616 dual sim has a large 5″ screen, eight CPU cores and two SIM cards – add those up and you’d think the phone needs a big, beefy battery. Except HTC decided that 2,000mAh should be enough.

How did that work out? Well, the endurance rating is good enough but that big screen and octa-core CPU really take their toll. Read more »

The Samsung Galaxy K zoom packs a 2,430mAh battery, less that you would imagine looking at its bulk. Still, Samsung has had a few iterations to optimize its Exynos chipset for great power efficiency and the Galaxy Note 3 Neo got great results with the same chipset (but bigger battery).

Despite its camera-oriented nature, the Galaxy K zoom has full smartphone functionality. Read more »

Walking about with a 3100 mAh battery inside, the OnePlus One needs to show respectable performance. Of course, it does have pretty large screen to power on (a bright 5.5″ 1080p display) plus a powerful Snapdragon 801 chipset. So jump after the break to find out how it did in our proprietary battery test. Read more »

The Oppo Find 7 is only the second QHD screen-toting device currently on the market, and also brings some serious horsepower with it – enough to rival other mainstream flagships from Sony and Samsung in the performance department.

The Find 7 also has the added benefit of having a 1080p twin in the Find 7a, so we can see just how much extra battery life is required to power a 2560 x 1440px display. Read more »

The in-depth review of the Gionee Elife S5.5 is live on our home page, and as usual we are now going to share the battery life breakdown with you.

The Gionee Elife S5.5 is running on a MediaTek’s MT6592 octa-core chipset with eight Cortex-A7 cores, aging Mali-450MP4 GPU and 2GB of RAM. The phone uses the same 5″ 1080p Super AMOLED screen as the Galaxy S4 last year. We didn’t know what to expect as we haven’t tested this particular combo yet. Read more »

One of the most noteworthy features of the Huawei Ascend Mate2 4G is its beefy 3,990 mAh battery. The Chinese manufacturer boasts that the phablet has battery big enough to charge other phones too via a dedicated cable.

The current champion of our battery test, Nokia Lumia 1520 managed achieved the whopping endurance rating of 107h with a 3,400 mAh battery and more demanding hardware on board. As a result, our expectations towards the Huawei Ascend Mate2 4G are quite high. Read more »

The LG G3 is the first mainstream smartphone to out a smartphone with a QHD display, and as such is the first major manufacturer to have to deal with the extra battery load required to power such a robust screen.

LG has thrown in a 3000mAh battery to power the device, and while that sounds pretty great it’s unclear if it will be enough to make the G3 a battery life king. Read more »

The Motorola Moto E has been around and before we are done with its in-depth review we’ve decided to share its battery life test results.

The Moto E is running on the very efficient Snapdragon 200 chipset relying on two Cortex-A7 processor cores and a big enough 1,980 mAh battery. The latest Android KitKat and its optimizations should help too. Read more »

Our review of the Sony Xperia M2 is live at our homepage and it’s time we share the full battery breakdown with you. The Xperia M2 has a 4.8″ display that needs to be lit up, but it also comes with a energy-efficient Snapdragon 400 chipset and a big enough 2,300 mAh Li-Ion battery unit.

We’ve already seen the 6″ Xperia T2 Ultra, also powered by the Snapdragon 400 SoC, do great in our battery test, so we’ve expected decent results from the Xperia M2 too. Without further ado, here are our battery impressions. Read more »

The HTC One mini 2 boasts many hardware improvements over its predecessor – it packs a bigger 4.5″ screen, the same Snapdragon 400 chipset but with four Cortex-A7 cores, instead of two Krait ones. There’s also a bigger 2,110 mAh battery over the 1,800 mAh unit of the One mini.

The software is new as well compared to when we reviewed the HTC One mini a year ago – the HTC One mini 2 launches with the most recent Android 4.4.2 KitKat with Sense UI 6 right out of the box. Read more »

Our in-depth review of the 6″ Sony Xperia T2 Ultra has been around for a while and it’s time we give you the full battery breakdown. The phablet packs a huge 3,000 mAh battery to power the massive 6″ IPS 720p display, plus it’s quad-core Cortex-A7 processor should be lightweight on the battery.

We were disappointed from the battery performance of the Sony’s previous phablet – the Xperia Z Ultra – so we didn’t expect miracles from the T2 Ultra either. We couldn’t have been so wrong. Read more »
