Recently I got my battery replaced and even though it has just one cycle it leasts only about 3 hours and it’s getting worse by every time I recharge… It’s acting almost like my old one (Mac shutting down with 20% without any warning etc…) Anyone had the same problem? Thanks

I think you need to allow the battery to fully charge (a good 24 hrs) to see what happens then. Both snapshots show normal conditions. The first is just a low battery and as you can see the charger is charging! the second appears to have almost a full battery and the discharging is what I would expect.
