Yes, would love to hear about the battery life. Ordered an i5/16/1TB that should be here in a week, and just wondering if I should switch to the i3.
Hey mate,
Battery life depends on your use case etc etc etc. Here's the i5 vs i3 test I did,
more info about differences in my full write up.

Battery - 2019 still reigns supreme, 2020 i3 was about 15-20% worse, 2020 i5 was about 40% worse.
I did two battery tests in the week I had the 2020 i5, so I figured it was only fair to replicate them on the 2020 i3 and the 2019 to get a proper comparison.
Note: these tests were done after all indexing and synching were completed.
Test 1: The 'regular, every day' test. 50% brightness. Browse the web in Brave (Reddit, news sites, occasional YouTube, never more than 3 tabs) until the battery life hit 50%. Then, switch to Netflix and stream the same video at the same compression until the battery runs out.
Test 2. The 'Ah crap I'm stuck on an international flight and I'm bored' test. Obviously not such a worry anymore (ha ha ha ha 😢). 50% brightness. Netflix, stream the same video at the same compression until the battery runs out.
For those interested, the chosen series for the streaming portion of the tests was Start Trek: The Next Generation, because hearing people stress about warp core breaches in the background was fun.
Results:
1. 2019 i5 MBA: Regular, every day test - 9hrs 13m. Stuck on an international flight test, 10hrs 20m.
2. 2020 i3 MBA: Regular, every day test - 8hrs 3m. Stuck on an international flight test, 9hrs 22m.
3. 2020 i5 MBA: Regular, every day test - 6hrs 20m. Stuck on an international flight test, 7hrs 35m.
So, what does this mean for me in real life? I'm going to use pre-Corona examples. With the 2019 and the 2020 i3, that's all day battery life for me. If I'm going to a bring-your-own-device professional course (which I do frequently) where I'll be scanning through multiple PDFs, taking notes, and making slides, I don't have to worry about bringing a charger.
That isn't the case with the 2020 i5 - for me, it was 'it could be all day if I gimped everything, turned the brightness to one notch and made sure I didn't look at the computer the wrong way.' Since the 2015 MBA, I've never had to worry about hobbling the machine to ensure a full day's battery life. I know many of you are coming from a Macbook Pro where 6 hours might seem great, and if that works for you, cool. But I'm just not interested in turning off built-in essential functions like Turbo Boost to make it through the day or reduce temperatures - it shouldn't be necessary on a $1500 machine.
One of the main reasons I buy Macbook Airs is to reduce the amount of crap I have to carry around. I don't want to buy a power bank, I don't want to be playing the Hunger Games to try and get one of the few power points on the base where I work or at airport terminals, I don't want to be hunting around like Smeagol at a cafe for an abandoned USB-C charger. All day battery life is important to me, even if it might not be for you.'
