Hello. I have a Macbook Pro Retina 15 inch from 2012. I´m only getting about two hours af battery life even if I´m only using Safari and listening to some music. The battery is discharging with 22-27 watts according to coconut. Isn´t that a lot? It has only been through 350 cycles and I´m not getting any service warning.

Nothing running in the background and the only app with a black dot is Finder.

You can use the Activity Monitor to check the energy usage Stefan is talking about, though it doesn't show everything. The power must be going somewhere.

Your battery is definitely not in the best condition. I believe that laptop is rated for 1000 cycles before reaching 80%. That would definitely contribute to lower battery life (regardless of usage).

Your computer's five years old. Think it's time to get a new battery.

Download gfxCardStatus and set it to use integrated graphics, if battery life improves, then something else was using the dGPU.

Your machine is 5 years old though, it could be the battery but the load cycle doesn't seem bad.

I've found Safari and listening to music doesn't guaranty efficient battery use. Safari varies wildly depending on the site I'm on and if I have adblockers running. Also, music streaming from my NAS uses double the power of streaming from spotify. You can run little tests like seeing how each site uses different watts. You can squeeze more efficiency with some testing.

Today I tried to use Chrome instead of Safari and I have more than doubled my battery time!

It's a good time to get your battery replaced anyway. Next year you MacBook will probably be 'obsolete' so you won't be able to get an official replacement battery. Instead you may have to go for a third-party one which may or may not work as well, and will affect the resale value.

That happened last year to my 2009 17" mbp. I left it too late :(
