iOS 4.3.1 or Jailbreak caused battery life to become poor?

[Hustler1337]

Hi,

So, I've jailbreaked my iPhone 4 a couple of days ago for the very first time from iOS 4.2 and have notcied that my battery life has become quite ******. With general use, my battery would go down by quite a bit compared to when I had it under iOS 4.2.

I am not sure whether this is iOS 4.3.1 itself or the jailbreak (as this is my first ever jailbreak). A single full charge would last me a full day, but it seems that I can use up the battery sooner than that.

Or is it just me imagining something?

The jailbreak can't effect your battery life, but what you install using Cydia can.

Same for me but it was this way before I jailbroke it on 4.3.1. It is really really bad though.

Case in point - left work yesterday with 100% charge. Played Tiny Wings for 45 minutes, replied to 2 emails, and talked on the phone for 1 hour. Woke up this morning (13 hours after the charge to 100%) with 32% battery left. That is ATROCIOUS! Previously I would have had probably 70-75%

I have had so many problems with iPhone 4 replacements (this is my 5th!) that the last time Apple sent me a brand new retail one straight from the factory. I don't know if I want to get into the replacement game again because otherwise the phone is perfect
