I know there are many subjective things that affect a battery, but seem to have low battery life with the 6100 ... charged battery from dead tuesday am. phone had no signal @ wifes work all day, so it was in powersave mode till she left. has called about 15-25 minutes last evening and today, and it is down 2 bars already. is this normal for the new larger screen flip phones? used to have nokia with lcd screen that battery would last a week!
