Battery For Lg G4
BATTERY Removable Li-Ion 3000 mAh battery

The LG G4 comes with a 3,000mAh battery - the same capacity as the G3 and the G2 before it. The G2 was a battery life king, but the G3 was quite average. Our tests show that the LG G4 also fails to recoup the G-series former glory.
The Endurance rating worked out to 54 hours, 9 hours less than the G3. The issue was with the high standby power draw, which puts a strain on the battery even when you're not using the phone. The other disappointment was the talk time, which couldn't reach 17 hours - an 8 hour drop from the G3.
We reran the tests several times and kept getting the same results. The LG G Flex2 got basically the same results so we wonder how much responsibility Qualcomm shoulders for the lackluster battery life.
Anyway, the web browsing time was pretty good - nothing spectacular, but good. It also marks the only improvement since the G3 as the video playback is below average for the flagship class.
