The Good...
When you put the Everun in "Power Saving" mode (Speed) and Wifi/BT off, the Expwin reports around 11 hours 42 minutes of working time, which is incredibly! Not the 12-13 hours advertised, but we all know that specs from manufactories are a little over the top.
So you can do a lot of eBook reading or working with documents.
When you switch on Wifi ("normal" mode) and the processor to "auto", the predicted using time drops to about 9 hours 43 mins, which is still a lot.
Still, you have to remember that when actually using the device, and the processor is going to work hard, the indicated usage time will decrease.
The Bad...
The device feels real heavy with the extended battery, up to an "uncomfortable" level. You really have to get used to the new weight. Still, I have no problems keeping the device in my hand for several hours. Holding the device in portrait mode is more comfortable than in landscape position.
The Ugly...
The battery looks...well, uh, ugly. About 5 millimeters stick out of the device. The Everun never has been a "sexy" looking device, but with the extended battery the "nice" look is definitely gone.
Conclusion
If you want more battery power that will get you through the day, you definitely gonna like this extended battery. No more worries about low power messages, which was the main reason for me to buy one. Ofcourse you have to live by the drawbacks: weight and (lack of) looks.
I, for sure, am not going back to the standard battery!
