I’ve just upgraded from an M1 Pro to an M4 pro. Battery life was not my consideration, as the old battery is great and has never had much stress/many cycles. I’ve used Al Dente for some time too. But that’s not the point of my post.

I find that even though I didn’t find the M1 slow in general use (but it definitely needed some patience at times — I’m a photographer working with large files). The M4 Pro is just so much snappier and nicer for normal use, even though spotlight is still running from the setup. The extra snappiness is very noticeable and nice. I got the nano texture screen, which I find I’m loving. Overall a better upgrade that I would have thought.

And for battery, in the research I did before the purchase, it seems the M3s do better in battery life than the M4 if that’s your main consideration. But likely any M3 you buy will have a battery with an older manufacture date. M3s are available as refurbs from Apple, and it’s likely that Apple puts a new battery or a young one in for a refurb.
 
I am using the M1 Pro since release now every day for multiple hours. Mostly for university stuff like taking notes. In the afternoon, the IPad gets used to watch videos and doing some art with procreate.

The problem is now, the M1 Pro won't take me through the day at university anymore. I normally need to charge it at least once in 6 hours. I was thinking about either getting the battery replaced or buying the new M4 pro. 120hz is a must for me. OLED is cool too, I have OLED on basically every other device I use nowadays.

The battery replacement would be 130€.
The M4 Pro and pencil pro would be around 700€ with student discount and trade in money from the M1 Pro.

What would you do?

Rui no onna, i remember you have PWM issues with OLED, but the 12.9 Mini LED iPP screens also have some PWM, do you get any issues at all like headaches? (Sorry off topic a bit).

Migraines during the first week but then those went away. Iirc, the Mini LED iPads use higher frequency compared to OLED.

I am at 492 cycles and 75,39% according to the automation in the analytics.
This is the PowerUtil data for my M1;
cycle count:743
calculated battery health:92.29
average temperature:23˚C

Average screen brightness is 25% and i tend to keep the battery percentage left
between 30 and 80.
 
I think there is alot of false information going around in regards to batteries and Apple is benefiting from it. From my understanding if you are trying to get a free battery swapped under AppleCare the battery needs to be below 80 percent capacity. Ifs it an out of warranty repair you are supposed to just pay the fee for the replacement and doesn't matter if its below 80 percent. In regards to iPads they don't change batteries and they will give you a new iPad. I think that's the reason why it's harder for iPads because Apple just wants you to buy a new one so they make it difficult for you to get the replacement.
For Watches, you have to get to 79% capacity before they will replace it, even though it is out of warranty and you are paying. In the case of Watches, they are giving you are replacement device, not just a new battery. I went through this late last year. My S7 watch had gotten to 80% and it was driving me crazy. Apple wouldn’t replace the battery until it officially went below 80%. That took about 3 months. The replacement Watch doesn’t have the oxygen sensor but it was worth that to get more battery. I don’t think I’ve used that sensor more than a couple of times, anyway.

If you use your iPad without any accessories then upgrading might be an option. However, the Apple Pencil, Magic Keyboard and/or Smart Folio for your M1 will not work with the M4, and you’ll have to purchase these all over again, significantly increasing your cost.
 
replacing the battery, a.k.a. getting a whole refurbished unit from apple, is significantly cheaper and easier than
selling the m1 and buying an m4.

if i have an m1 i would replace the battery.
