The G Flex 2 is better than its curved predecessor in every way save for battery life. It packs a 3,000mAh battery instead of the larger 3,500mAh size in its predecessor. You're not going to get two or more days from this handset, but are in the clear for all-day moderate use.

LG G Flex 2 review

TechRadar's smartphone battery life test proved it to last much longer than the LG G3, which also packs a 3,000mAh battery. Running a looped HD video for 90 minutes, the battery drained by 13%, while the G3 went down by a whopping 30%.

The difference? LG G3 is firing up way more pixels on account of its energy-sucking Quad HD display. Plus, to a lesser extent, it's not running the better-optimized Android 5.0 Lollipop OS.

The 6-inch LG G Flex from 2013 dropped by just 6% from a full charge, but the rule of thumb is bigger phone size, bigger battery. The shrunken LG G Flex 2 had to compromise on the size. I just wish LG didn't also settle on a non-removable battery. While the curved phone's back cover can be taken off to access the microSD card slot, there's no way to swap out the battery.

Can't swap out the battery

On the plus side, the LG G Flex 2 now features fast-charging capabilities via its included travel charger. It's akin to Motorola's TurboCharger for the Droid Turbo, Moto X and Nexus 6. It charges 50% in 40 minutes, and I was able to reach a full charge in 1 hour and 38 minutes from a completely drained battery.
