2012 Retina Macbook Pro Users: How's your battery life now?

[Woodcrest64]

For those who own a 2012 Retina Macbook Pro how many hours on 'average' are you getting on your battery now?

I've bought my rMBP in Sept. 2012, this is now 1y and 8 months ago.

The battery life is still remarkably good after around 200 cycles I still got 7 to 10 hours in OS X and 4 to 6 hours in Boot Camp. I think it's just a 3-5% decrease since the beginning.

If this rate continues, the replacement battery will be due after about 4-5 years if nothing else fails.

My Dell laptop from work has decreased its battery life from 4-5 hours to 3 hours after one year.

Is the iStat battery health accurate? It is showing 100%/99% for my rMBP 2012 which seems quite a lot for almost two years old laptop. Otherwise I am getting around 6-7 hours of heavy use, including videos, safari, music

That sounds about right for a 100% 2012 machine, that is what you would have got out of it originally.

Any idea how much a replacement costs? I had my 2012 retinambp's battery replaced under apple care and they swapped the entire bottom chassis for it.

I think Apple charges 199$. It replaces the battery and the lid with the trackpad. You can do it yourself for about 60$ off eBay and 1'hourmof time and patience. The task is not for the faint of heart though

Now after 4 years and 4 months I still haven't replaced the battery. 85% with 315 cycles. Lasts around 7-8h browsing and 3-5h on more demanding usage. They'll charge $199 and replace the whole top case including trackpad and keyboard. Although mine looks and types like new after 4 years of heavy usage.

For comparison: My Dell laptop has already a replacement battery and this one is at <70% lasting me 45 minutes max after 1.5 years.

Don't buy batteries from ebay, they are far away from the quality Apple offers.

Macbook Pro Retina 2012 15" with basic configuration. 487 cycle, working about 3-4 hours but I always use GT650 graphics (Because of this annoying bug with graphic switching).
