Who I have the same questioned this topic

i am a moderate/heavy user. I make around 10-15 calls a day, 30-40 emails, 100 texts a day. before the original 5.1.1 build i was charging my phone 3 times a day, after the original 5.1.1 update my battery was working great and lasting me at least an entire day. Now after the new build my battery is draining at the same previous rate, and i am having to charge it around 3 times a day. I Went to get a new battery and was told i had to pay for it even though i pay for the warranty/insurance through verizon because my battery was a couple weeks out of warranty. Why am i paying for additional warranty if im not getting the warranty coverage?

i was actually able to get a free replacement battery from Sprint, and not my service provider verizon which i pay.
