A comparison in terms of battery autonomy would look like this:
Nokia X3 Touch & Type seems to have a significantly greater autonomy given that is not 100% a touchscreen, even if apparently has a lower amperage.
Samsung Wave 525 has a reasonable battery and suitable for a touchscreen and considering that it is not a 3G phone, it is likely to have a very good range for a phone with touchscreen.

From the perspective of the Internet, we can say that these two phones have very common points: they both need an internet package to function at full capacity in terms of facilities it offers. In fact, this is something that we continue to say, because the technology evolves in the sense that the internet must be as mobile as possible, and manufacturers response to these needs are very good.

Samsung Wave 525 hasn’t 3G, so you can surf the mobile internet at HSDPA speeds, but that does not mean you can not navigate at all. Phone ”moves” very well on mobile internet even at EDGE speeds. In addition, it features Wi-Fi, so if you connect to a wireless network .
Nokia X3 Touch & Type has 3G, and download speeds can increase up to 10.2 Mbps. In other words, the phone “knows the net” .
