The family and I took a 24 hour train trip to Glenwood Springs over New Years. The only outlet in our "room" was 5' off the ground, and dangling the phone by the charging cable in the train was not an ideal way to recharge. But since I brought my spare battery and charger along, it was easy to swap out a dead battery and charge it in the room next to us while I continued using the phone. Thank you LG for keeping a removable battery !
