Longer battery in 2010 or 2011 13" MBP?

[MacBookPro13"]

The 2010 model boasted a 10 hour battery and the 2011 now boasts a 7 hour wireless web battery. On my 2010 model I was able to get around 4 or 5 hours wireless web, so does this mean that the 2011 model has improved battery life?

Any of you who had both models, can you tell me what the difference is between the two battery lifes?

Cheers

I have both models, my 2011 lasts just as long as my 2010 does doing the same tasks.

No issues with the batteries here

Apple has just refined their battery tests which gives different results under testing. The batteries are identical in both models

It's the same battery, but Apple changed their testing criteria, so their estimates would be more realistic. This should answer most, if not all, of your battery questions:
