That would make sense if they had the same hardware. Different hardware absorbs different current. You cannot deduce anything from battery size.

- nikanj 8y agoI've had the pleasure of upgrading from a 2015 to a 2017. The battery life on the latter is definitely worse, no matter what the official specs say.
- thebooktocome 8y agoI concur.
- saagarjha 8y agoIt is, but I haven't found it to be significantly worse. About an hour less.
- reversengineer 8y agoMany people would describe an hour's difference to be a "significant" change, especially when a scale of around 10 hours total battery life is being considered.
- saagarjha 8y agoSure, but considering the "fudge factor" that Apple often applies for their battery life estimates ("casual browsing", etc.) an hour isn't all that much.
- davnicwil 8y agoYeah I went from 2014 to 2017, and went from broadly not worrying about doing 6 hours of solid dev work without thinking about battery to essentially never feeling comfortable away from a plug. I'd guesstimate I get at most 3 hours on the 2017 before the battery level gets low enough I have to start planning where I'll next plug in. Not ideal.
- blueboo 8y agopart of the issue is if you have anything other than textedit open, the discrete GPU is on hoovering up all your watt-hours.
- jammygit 8y agoI think decaying batteries might drive people to get new machines? Just a suspicion. They do it with iphones :p
- bluescrn 8y agoIt’s certainly an incentive to upgrade, but only if the newer model is a clear upgrade... I suspect that Apple will be seeing a lot of 2015 MBPs brought in for battery replacements...
- wild_preference 8y agoAll batteries decay.
- hamstergene 8y agoThat's kinda the point... Instead of using more energy efficient new gen CPU to add ~3 hours of life, Apple used it to make the already perfect laptop insignificantly thinner and lighter by reducing the battery size.
