Let me see: A "1300" mah battery powering:
1. 65nm Snapdragon at up to 1ghz
2. 3.7" display
3. Live wallpapers (most that complain about battery use them)
4. Social apps in background (same as above)
5. 3G
6. GPS
7. Videos
8. Games
9. Texting
10. Camera
11. Web browser with Flash
12. Audio / Music
13. Widgets (same as further above)
Some users may be not appreciate what it takes to run the devise with a bunch of stuff will last a whole day (unless you only make a few calls and little else). Not to mention battery use is one of the most subjective things evah'.
If people want a wimpy 1300mah battery to last the day powering the hardware:
1. Do no use live wallpapers
2. Do no use widgets (at least NOT the social apps)
3. Leave GPS off
4. Leave auto sync off
5. Turn social apps off and refresh manually
In your all's defense, Verizon should NOT have released a 1300mah battery in this anyway, but then the same people would probably complain the device is not thin enough.
Some people and VZW are too funny

Then again, putting a 1300mah battery in a device like this is not
