I have a ryzen 5 3500u Acer aspire a515-43. The designed capacity of my laptop battery is 48wh but now he full charge capacity has reduced to 35Wh in just 2 months. The laptop is brand new. I also noticed that the adata m.2 ssd gets hot like to 75 degrees sometimes (not always, this happened to me 3-4 times only). And the ssd is quite close to the battery. Is it because of the ssd that the full charge capacity has reduced?

    I have heard that if the battery gets too hot(in this case due to the ssd) the full charge capacity gets reduced.

    Sounds like a lot of degradation for just two months of use, it does depends on how you're using it though. For example, you're right that lithium-ion chemistries aren't keen on hot environments but I doubt an SSD its side would be the major factor in this (not saying it is not, but it doesn't feel probable to me).

    Another thing that those kinds of batteries don't like is being completely discharged, it's better to keep them in the 15-90% range for example, or if you're playing /using the laptop for long periods of time I think keeping it connected to the power adapter is actually better towards battery health. At least by now manufacturers should have that worked out and only trickle charge, or use the adapter directly bypassing the battery, I don't know.

    Anyway, another possibility is that the battery you got is a dud, and while batteries aren't generally covered in the standard warranty because it is understood that they degrade over time, if it falls below the 50% range for example within half a year I think they ought to replace it for free because it wouldn't be reasonable to think that kind of degradation falls under normal estimates.

    Another thing, unrelated but answers some questions, M.2 SSDs, specially fast NVMe ones do get toasty, their controllers specially but the memory chips as well. It's just how it is, hell they even sell some heatsinks for M.2 SSDs! Some are too big to be installed in a laptop while others, like some copper sheets with a pattern under 2mm say maybe, just maybe, be able to fit. It all depends on the inside headroom there is in that area.

    In any case, I would monitor the degradation over time, I think there are apps that do it for you or you could keep a spreadsheet and annotate them yourself (off the top of my head, Nir Sofer's BatteryInfoView or Battery Mode can show some statistics, while others have graphing abilities and all),

    @aphanic is it a possibility that the battery is not calibrated properly? I used the power config report which windows provides. I usually use the laptop on ac power. Do you think if I calibrate it, the value will be more accurate?

    You could give it a try, deplete it altogether (for example while in the BIOS) and then recharge it to its maximum with the laptop off. Turning it on, firing up BatteryInfoView (still with the AC connected) and then disconnect it, see if anything significative changes like its health indicator of the % of charge jumping quite a lot.

    Without examining that battery myself with a probe I'm afraid I can't give you any more tips on its state :(
