Mobile phone companies charge a fee to download photos and music to your device. One reader at CNET outlines a budget-friendly alternative:

“I use an inexpensive Belkin bluetooth USB device I bought at CompUSA to transfer everything between my families [sic] five different cell phones and the computer at no cost. We use AT&T, T-mobile, and Sprint phones made by Samsung, LG, and Motorola. My kids always want to download photos and music to their phones, we also make our own ringtones and upload them to the phones. I can't afford the data transfer fees charged by the phone companies, nor did I want to buy five different data cables. We do it all for free with the one device.”

Spicygadget.com offers 4 tips for extending the life of your lithium battery. They include:

• Try to avoid frequent full discharging of the Lithium battery.
• For lithium battery meter calibration, periodically do a full battery discharge, every 30 charges, to increase meter accuracy.
• Avoid heat—it’s the Lithium battery’s enemy. The temperature in a car can easily rise to 50F in a single hour, in some cases reaching 140F.
• If you plan to place your lithium battery in storage, be sure to have the charge at 40% and stored in the fridge (not freezer) for maximum battery longevity.
