After updating to 4.1 we are not getting a true display of battery levels it seems… I see a LOT of threads on Apple’s own forums about bad battery life with 4.1 (on all iPhones) but I wonder how many realize it’s just a bad display of the battery life, or at least it is for me…

My battery can look almost empty but I don’t get the 20% level warnings… Then later on it’ll still show almost empty and just die on me. I can then charge it up again and it’ll still showing almost empty even after charging all night.

 

Then I just decided to turn it off and back on (standard way, holding both buttons until I got slide to turn off) and somehow I went from an empty battery to a full one just by turning it off and on?

 

Is this a known bug with iOS 4.1?

 

This is on an iPhone 3G.

 

Thanks.
