Here's the best comparitive article i could find ATM. Toshiba p100-222 review I could only find your model mentioned in portugese, so I suppose it's sold as a local variety to yourself, but should be basically similar to many other p100s worldwide.

Your battery life seems a little short, but that could be due to a few reasons.
You may need to "optimize" your battery life with optimal settings. Usually this is automatic, but you should check. Set performance to Maximum Battery life, turn off wifi + bluetooth when not in use, Set your graphics to minimum 3-d performance on battery etc. I would expect you could get more time than you are, perhaps closer to 2 hours depending on how big a battery you have
Look in the BIOS, sometimes there is a battery conditioning utility.
This will completely drain, then charge the battery to allow the system to set a reference point for the cells. The battery may not be charging all the way simply because it thinks it is fully charged.

This process usually takes several hours so I would do it at night.
I contacted Toshiba in Portugal and they will replace my battery free of charge. They say some models that came to Portugal had flaws or were for the wrong models. Just checked and mine is for less powerfull models.
