The "LG V10" has been getting praises ever since its announcment. With a set of specs and features the device comes with, the phone really deserved attention. However, According to GSMarena, the "LG V10" has 2 potential bad shots, first, the Snapdragon 808's GPU isn't the best when it comes to 3D gaming, and second, the 3000 mAh battery may be a bit small for the phone's size.
The "LG G2" phone from 2013 was way smaller and lighter than the V10, but it had a 3000 mAh battery despite its non demanding specs. The display was less battery consuming, making the 3000 mAh battery more than reasonable.
The "LG V10" may need something bigger not only because of the regular demands of a smartphone, but also because the "LG V10" has something to add up to the battery consumption - its famous second screen. Tech website GSMarena ran a standby test on the "LG V10" with that second screen turned on and off and they found out that it can lead to an increase in power.
Nevertheless, the endurance rating impact isn't that big, the figures involved here are 56h when the second screen is off and 46h when it is on. So whether it is on or off, you can get about 2 days of usage with moderate use. There is also a battery saving option or technique, just choose to only enable the second screen when the primary display is turned on. This can stretch out the battery a bit.
The whole "LG V10" endurance test resulted to a 'not bad' but 'not impressive' set of results. The phone can last 16:40h on 3G talk time, 8:20h on web browsing, and 7:30h on video playback. The talk time was a bit disappointing as there are other phones with the same battery size that can last way longer than that. The "Samsung Galaxy S6 Edge+" for instance, it has double the figures the V10 has.
As a conclusion, if you don't mind the constant charging, the "LG V10" is a rather impressive phone. It has a 515 pixels per inch display, 4 GB RAM, and a shock resistant build. Overall, it sounds like one beastly phone, only that there are better options when it comes to battery life.
