How To Destroy Your Evo Battery Life

For far too many days, blogs everywhere, including here, have been writing how to get the MOST out of your EVO battery. Well, today we tried a different challenge – how quickly can we KILL the EVO battery. So, without further ado, our wonderful scientific test…

Our test begins at 8:57 am with a 100% charged battery. We flipped on Sprint TV, Bluetooth Audio and started our 3 hour tour…

30 Minutes in our JuicePlotter grid shows us down 17% to 83% battery remaining. With the usual drop when the EVO is unhooked, this isn’t too far from what we expected.

An hour in, the battery has dropped an additional 12% to 71%. A 12% drop in the second half hour really made us wonder how long this will hold. That’s a 29% drop in hour number 1.

Now drifting into the hour and 30 minute mark, the battery has dropped below the 60% mark and fallen an additional 12%. This seems to be a pattern of about 25% per hour on Sprint TV, regardless of if you are using Bluetooth Audio or not.

Finally getting to the 2 hour mark, and surprisingly we are only down to 44% – even if we missed it in the screen capture above. A bit more severe drop, as we were down 15% in this half hour period, but it’s still holding steady at that 25% per hour discharge.

Finally, at 18% remaining at 2 1/2 hours in, the battery is done. It played TV for about 3 more minutes before the 15% battery warning kicked in and the TV stopped. So, the full battery life for a maxed out EVO is about 3 hours tops – but closer to the 2 1/2 hour side of that measurement.

We’d love to see your results of the stress test like this – email us at smartphonedeals@gmail.com and let us know how your EVO does!
