My new iPhone has caused a battery drain from extra time I now spend using the phone and its many apps, etc. I researched and ordered a back-up battery for around 50 bucks from RichardSolo.com ---- works great. I carry it in my briefcase and have a spare now for those nagging moments of uncertainty! I checked out the others available and chose the RichardSolo. Curious how others are dealing with this low battery issue?
