Re: Cell Standby Eating Up Battery. If you are getting more than a day's charge from a smartphone then you are doing well. Basically standby time in Airplane mode will get you the 8.3 days of battery life or longer. I think I went almost two weeks on my Droid Eris in Airplane mode before needing to charge it.t can't send or receive calls, texts, that's not standby. My former dumb phone held a charge, with use and left on all day and night, for a week. My smart phone if I use it carefully, 2 days and I must turn it off at night.
