Not happy iOS 6.1

I have an issue with my iPhone 4S.

Ever since this update over a moth ago. My battery life drains really fast.

I've done what everyone suggests. Make the phone useless by turning everything off.

Still it dies really fast.

Clearly an issue with the update.

My battery drains at about 2-3 % every few minutes. Currently at 49%*.

It freezes seldomly when unlocking, sometimes while I text. My words will disappear, then reappear and when I type the words I type disappear but are still there cause I can highlight and copy them.

So little bugs I can live with. Those rarely ever happen.

However my battery life I need.

Again. It was flawless before the update. This stuff never happened.

My phone is in mint condition. Placed it in a defender series otter box before I left the store. And I only remove it to wipe dust off the phone and charge it.

So it's not misuse. Never dropped it.

Could this be a bug or defective hardware?

I've been patient, waiting for the bug to be fixed

. Now I'm slightly peeved. If its my hardware that apple sold me less than 1 year ago. I'll get it tested and replaced for free right?

This is my first iPhone and I do enjoy it. Love it. Recommended it a lot.

If this is not resolved. I will never buy apple again. Bad first impression to me.

I'm only one person. But one person who cares about being treated right by the people who sell me such items.

Thank you for your time :)

Battery at 46% now. After a 2 minute message.

That's not right.

Defective software or hardware???

Sincerely,

Annoyed apple user.
