Fellow Nook Color enthusiast and Word Feud rival, Ryan, sent in this tip for improving Nook Color Battery Life. It involves disabling a core service in the Android OS called “Cell Standby Service.” It’s normally used to allow Android cell phones to receive phone calls & text messages while on standby. However, seeing as our Nook Colors don’t have these telephony functions, it’s a waste to have this service on and wasting battery.
Head on over to addictivetips for detailed steps for how to turn off this battery wasting service.
*note: it’s uncertain how much battery this will save, but it definitely can’t hurt to try, and it’s a reversible process. I will do some battery tests and post the results.
