First of all, only the voltage is printed on the battery itself.

Second, I experience worse uptime than on my original 1400 mAH battery.

Third, I guess Iam just sceptical by nature.

So my question: Is there an app out there that will display max capacity?

Or do I really have to measure it with a multimeter?

the only way to measure precisely is using an app called
battery monitor widget
have it measure the current and voltage every 60 seconds
fully charged ur volatge suppose to be at ~4.2V with either battery
the drainage suppose to be the same at screen off
lets say ur phone drains 9mA steady

u should see the voltage sinking slower on the higher capacity battery
i would give it an hour or 2 hours on each battery to check the result


1400mAh battery

steady 9mA current over 2 hours from 4200mV down to 4150mV

2600mAh batter

steady 9mA current over 2 hours from 4200mV down to 4175mV

hope it helped^^
