Q: New battery, disappointing runtime.
I've had the battery replaced in my MacBook Air (13-inch, Mid 2011) 1.8 GHz Intel Core i7 with 4 GB 1333 MHz DDR3, and I'm only getting 4-41/2 hours out of it, which is not much more than the battery it replaced. I'm not doing very battery intensive stuff. Email, internet (flash switched off), and I've turned down the screen brightness.
I'm sure I used to get much longer when the machine was new, is it possible that the incorrect capacity battery has been used and is there any way I can check?
I'm running El Capitan 10.11.3 (15D21) BTW.
TIA.
