With a 1500mAh battery on board you might expect great things from the Samsung Wave III, but if you are a regular reader of our reviews then again you might not. The Samsung Wave III has a big screen to keep powering on, and this is a drain. The 1.4GHz processor might not be dual core, but it too needs fuel.
The long and the short of it is that you'll probably get about a day from the Samsung Wave III unless you are frugal.
A typical day for us involved powering on at 7am after a full battery charge. A few short phone calls, some email, some social networking, 3G and Wi-Fi based internet access, music playing and a little bit of GPS left us with 54 percent battery life by about 5pm.
We then left the phone untouched till the following morning at 7am, but which time the battery had fallen to 36%. Under a similar regime to the previous day it was at 0% by 10am.
In addition to the connectivity options we mentioned just now there's DLNA streaming and Bluetooth leaving you with, as estate agents like to say 'all mod cons'.
