Choice between wp8 and wp8.1

[WPCentral Question]

Hello guys. I've just bought an old lumia phone 720 which comes with wp8. I always read comments about wp8.1 that make troubles battery life. 720 has 2000 mAh battery and it's totally enough for me during day. So would you recommend me to upgrade my phone to 8.1? Or shall I stay at wp8 just for battery life -and it's important for me- Thanks.

There's no appreciable difference in battery life between WP8 and WP8.1, you'll be fine to update.

Minor updates on system structure, only GUI changement

You should update.... at least beacause of new apps which may not run under 8.0... the batery live depends more on background task like cortana .... and you can switch them off
