I've been using my cheap-ass 4 years old Chromebook pretty heavily on the battery, yet it still manages to last about 7 hours. I'm impressed.
@ayo AFAIK Li-Ion batteries degrade when you keep them 100% charged, so if you use it heavily, it should be good for it.
The upfront cost alone of an additional battery, the planning of bringing the good battery, etc.
My 1911 days old battery still holds 80% charge after 907 cycles, which is plenty for both use cases and the laptop is definitely not worth the cost of an additional battery by now.
And if I have to theorize, I'd still bet on 100% charge over high load cycles. There's a *steep* downhill curve at 1100 cycles 😅 https://www.coconut-flavour.com/ccbonline/index.php?modeltype=MacBookPro11%2C1
If I'm buying a new battery anyway, and have a limited choice as it has to be compatible with the laptop, I'm not gonna risk using it when I don't need it.
@Wolf480pl @ayo I understand the desire to buy an insurance policy (an additional battery), but it's still just anecdotal evidence from one battery life against what appears to be a trend on multiple different laptop models 😄
Sadly I can't find stats for how much data they have, and it's not exactly proof without some kind of controlled group, but it's still very suggestive.
