Battery life after full charge?

Have just fitted ifixit replacement battery to my iphone. Everything works but Max battery life is similar to replaced battery which was original(5years old). With no phone and no Wifi selected and just clock displayed total duration was 10 hrs to 10%. What duration should I expect from replacement Battery?

When turned off there is no drain. Sim card had been removed so there would have been no phone activity during the test. I think that my main concern is that there appears to be no improvement in performance with the new battery when compared with the old.

I'm not sure of the definitive answer but you are using power just displaying light/clock or when phone is in sleep mode as phone is still connecting to mobile towers etc. You will only have no drain if you power off using "slide to power off".I generally go through 1 charge per day on my phone . If you turn phone off completely following a full charge and you have a drain on the battery then I think you'll need to check your soldering job- sometimes there's just a little touching from one lead to the next.
