Hi,

I’ve got a MacBook Pro (early 2015, 13” retina) that’s about 3 years old. Battery goes flat overnight while it sleeps. I guess it’s probbaly time for a new battery. Has anyone had heirs replaced somewhere and remember the cost?

Oobe said $500-700 but if I gave it to them for an $89 assessment they cold give me an exact price. I’m a little confused why they wouldn’t be able to tell me a more accurate cost when they given the model number!

Hi - I can’t really be much help but something doesn’t seem right unless the battery has been abused in some way - I would expect a battery to still be pretty good after only 3 years (with these newer gen MacBooks).
I’m surprised that it should flatten overnight - my Mac laptops have generally used 3 - 4 percent sleeping overnight - it sounds like there may be an app failing to shutdown, or your power settings are not letting the thing sleep properly, or something is going on with network settings....??
That price seems high, but I haven’t had experience with getting a replacement. Have you checked your battery status by clicking on the Apple icon, then About This Mac, then More Info, then viewing the battery cycles...?

Cheers,
Mike

Ok, thank you. It says health information: cycle count 125, health: normal. I assume it adds together partial charges to make up that number somehow. The battery has just been used.. as normal. It seems to have come on rather suddenly, so I’ll charge it up, make sure all apps are closed, and see how it goes.

It would pay to double check if it’s more or less than 3 years since the date of purchase... those batteries are supposed to hit 1000 charge cycles before they’re ‘consumed’ and their runtime is noticeably reduced. If it has developed a fault then you’re that much more likely to get coverage under a customer satisfaction exception if you’re below 37 months old (3yrs 1 mth) without having to resort to the CGA...

However a more likely explanation is that a rogue app is preventing the Mac from sleeping properly (looking at you Adobe/Chrome).

Either way, OOBE (or any other AASP) should be able to run a quick battery diagnostic at no charge to you. I’m not 100% sure what data the diagnostic brings back for Mac but on iOS devices it can give a good idea of what apps are using a lot of power. At the very least the diagnostic should indicate if there’s a fault with the battery itself - because if not a replacement won’t help.

Edit: clarity around CS exception vs CGA

I charged it to 77% last night. Made sure all apps were closed, then closed the lid. I had a look just now and it’s down to 66%. So 11% change in 15 hours. That seems more reasonable.
