As you can see, both the overall battery usage time and the screen on time are very mediocre. I don't game at all on this thing, and I don't do any intensive video uploading at all. My screen is set to about 40% brightness or so, yet I am still getting very poor mileage out of the battery. I know when it came out, battery life was considered average at best, and was the one major knock on the phone by most reviewers, but 6 hours battery life and not even 2 hours of SOT seem rather putrid.
To help offset this, I picked up an LG Stylo 2 plus for $50 and the minimum battery life I got on it to this point is 14 hours, and while on a Netflix marathon last Saturday, I got over 8 hours of screen on time, and a total of 25 hours 16 minutes battery usage since the previous full charge. Granted I know it doesn't have the pixels to push, and doesn't have the processing power to supply like the s6 edge does, but still. That near 6 inch screen phablet ran circles around the just over 5 inch screen s6 edge in terms of battery life.
Frustrating to say the least. S6 edge is still a good phone, but can't enjoy it much, or st least not to its max sith such tepid battery life.
