I have been VERY impressed with the battery life on the Samsung Galaxy Nexus i9250.
Like any super phone, especially one with a Super AMOLED screen, battery use is quite high when the screen is on and you are actively using the phone – no surprise there. What has exceeded my expectations is how slowly it uses battery when the phone is on standby, like when it sits in your pocket.
This screen cap shows how quickly it uses up battery when you are using the phone. I started with 100% full charge, and with well under 2 hours of constant use, the battery had already dropped to 63%.
This screen cap shows full drain of the battery from 100% all the way down to 1%. You can see that when the phone is in standby, the graph is almost flat – which indicates very little battery use. But during the times I’m actively using the phone, you can see the battery drains fairly quickly. I was still able to get 18hours and 46 minutes of use, which I was impressed with. Here is another chart of the same 18hr 46min period:
You can see that when the phone is not awake, and the screen is off, the graph is almost flat.
Finally, here is the best total standby time I have been able to get with my phone:
