Hi everyone, I was just wondering if anyone could verify that my battery's performance is abnormally crappy for my Sl5500. My friend gave me his zaurus, so I promptly went out and purchased an Ambicom WiFi card. Unfortunatly, I can only use it for about 10 minutes before my batter goes to "critical". This is coming off it being charged all night, and it having a full blue bar. Is this normal? If so, should I have paid extra for one of those "low power" wifi cards? Any suggestions? Thanks in advance.
