I think that every user who happens to have an Android device is always facing a problem of battery life. We all do know that Android smart-phones are great and that their greatness requires extra care and power. When I use my phone in ?working regime,? the battery is out at the end the day. While on weekends, when I do not need much from my phone cause I spend time with my family, I can reach up to 2 days of work. But, that is all. Yep, unfortunately, that is not some kind of old-fashioned black and white Nokia that allows you to do receive calls and answer messages the whole week. But, back then you were not able to watch movies, listen to the music and search the web on your phones. Anyway, battery is the weakest part of every Android. And while scientists are working to bring us something great that will allow using smart-phone?s battery for months, there is a little cure from Seidio Innocell. This company offers another extended battery and this time it is for the Nexus S. It even more than doubles the original 1440mAh battery for the Nexus S by giving you 3500mAh. Yes, you phone will become a bit thicker and ?fatter? but, despite that little fact you can prolong your battery life at least for one more day. The original package of Seidio Innocell 3500mAh battery for the Nexus S with the back cover and battery itself will cost you $64.95.
