Battery life is good for 4-6 hours without recharging, if used to listen to computer or make calls quite a bit.

I have it connected to my computer via USB for soft phone use

Of all my reviews on Amazon, this product is the most significant product that I have used and I have given the Plantronics Savi the highest review and praise of any other product t that I have ever rated o0n Amazon

Love this headset... can be used with phone system, computer or mobile devices!

But a solid 5 stars for a great product that I love using every day!
