iPhone 4s switch off at 40%

Dear Team,

In the last couple of weeks my iPhone (16GB 4S) shuts off at 40%. Currently the battery is the one which I got it from iFixit and replaced it few months back.

Not sure if the present behavior is due to any s/w bug. Could you please advise.

Thanks

Naren Nachappa
