Samsung Galaxy Alpha vs. HTC One mini 2: Metal mania

Battery life

The Samsung Galaxy Alpha raised eyebrows when it was announced with a 1,860mAh battery - most 4.5+ inch phones are well into the 2,000 milliamp range. At first we wrote that off as a sacrifice in favor of a thinner device.

The HTC One mini 2 is almost 4mm thicker and naturally packs a bigger battery, though not by much - 2,110mAh. It's a sealed Li-Po battery, while the Samsung has a user-removable Li-Ion unit.

Perhaps it was Samsung's custom-made Exynos chipset (the first mobile chipset at 20nm, while Snapdragons are at 28nm) but the Galaxy Alpha managed very respectable numbers, actually better than the One mini 2 managed.

The endurance ratings for both are virtually the same - 50 hours for the HTC, two more for the Samsung. You'll need to charge both every two days of moderate usage, every day with heavy usage.

But the Samsung Galaxy Alpha can give you three hours more of talk time, meaning you can make 30% more calls on average at the same charging schedule. The HTC One mini 2 does 10 hours - more than you can do in a sitting but less power usage during calls also means more power left over for other tasks.

The Samsung emerged from the Web browser test with a two hour lead. An 8 and half hour time is highly respectable considering the battery capacity and it's as much as you can expect out of a phone this size. The HTC One mini 2 did an average job at 6 and a half hours.

Finally, the Galaxy Alpha took home the Video playback title with another 2 hour win. Again, for a thin phone with small battery that's an excellent result. The HTC One mini 2 repeats its 6 hour time, which isn't all that impressive.

This leaves the standby power consumption to account for the small difference in endurance ratings. That's the one area the Galaxy Alpha could have performed better but the overall battery life is great as it is, certainly not the compromise we expected at the beginning.

Heavy users will get even less battery life out of the HTC One mini 2 than the moderate usage numbers suggest since its advantage - low standby power consumption - doesn't get the time to shine when you use up the battery in a single day. It will do better than the Samsung for low to moderate usage though.

Winner: Samsung Galaxy Alpha. The Galaxy Alpha won every single category and impressed despite its relatively small battery. It's user-removable too so
