LG G3 Beat only drains 1-2% every day while idle. Perhaps when Wi-Fi is on, it might give me 7 hrs while using a stock browser and downloading. On 3G browsing, my Xiaomi gives me 8+ hrs SOT continously while the LG goes 10 hrs. .
Both gens of Moto G had the Snapdragon 400 like my LG and Nokia Lumia 635. I really like that SoC. Low power consumption from Cortex A7. This is why the Huawei Ascend Mate2 had INSANE battery life. Snapdragon 400 with 3900 mAh. My Xiaomi after MIUI 5.18.x lost the battery saving mode feature where the CPU throttles down to 1.1 GHz. So when I play my PvZ2, I no longer get 5 hrs SOT but less than 4 hrs and it heats up more reaching 2.26 GHz unnecessarily. The LG G3 Beat at 1.2 GHz doesn't overheat that much or as quickly. Snapdragon 400 is like going on power saving mode on Snapdragon 800 or above.
Between 1-1.2 GHz quad for the CPU is a good range for me to keep the heat low and battery life longer while playing my games. Hitting over 1.5 GHz CPU speeds for all cores can sometimes be unnecessary to do even basic tasks that doesn't need it. I think my Apple iPhone 4, Xiaomi Mi 3, Nokia Lumia 635, and LG G3 Beat have all given me the best battery life with excellent idle time. The iPhone 4 once gave me one month standby in 2013 while on airplane mode. But I think this LG surpassed it. A replaceable 2540 mAh to power a "5 inch HD display. Has the perfect balance of necessary speed and features I need with long battery life. The G2 mini is even longer but only has qHD. But me likes the G3 Beat for the design and sharper display. G3 Beat (aka G3 S Dual which I have) is better than Moto G, HTC One mini 2, Sony Xperia M2, and Samsung Galaxy S5 mini for the price and bigger battery.
