i love the 1750. all i'd like to do is get through the day on a battery. the 1300 would be done by 5pm. i can go from around 7am in the morning and still have maybe 15-20% once i get to bed later around 1130-12. that's with my 'normal' use. on a lighter day i can still have 50% left at bedtime. i'm not going to be greedy and expect 3 days of use out of it but with wifi on half the time, screen brightness at 100%, gps and location always on, i'm happy. SO WORTH THE MONEY
by the way, NO IDEA if this is related, but i had batterylite installed on my phone and my phone rebooted twice in a day with it. when i don't have it installed? NEVER A REBOOT and this is well over a months time. very well might be a coincidence but that's not on my phone anymore.
