Hello, I currently have a 720 and I am planning to buy a 830.
My biggest concern is the battery life.
Usually my 720 lasts for a approx 20 hours.
Should I go ahead with 830?
Thanks
The 720's battery is 2000mAh and the 830's is 2200mAh. However, those numbers alone aren't sufficient because there are other factors to take into account like screen resolution as larger screens tend to require more power.
As ever, the biggest challenge with estimating battery life is how much you use the device and what for. I've just started using a 830 and its battery does seem to be lasting longer than my 925, which also has a 2000mAh battery. I don't know if that is enough help to answer your question, though .
