My husband and I got the exact same phones at the exact same time. Mine when down to the 15% warning level takes about 40 minutes to fully recharge. His takes about 3 - 4 hours. I've checked every setting I can find...nothing is different. We've both used his charger, and have both used my charger. No difference. Hmmm...haven't tried swapping the batteries. Maybe I'll do that next.How long should it take to charge this thing??
