I wish they made the batteries slightly larger, then made 100% on the battery meter secretly be 80% of the increased capacity so I could have my cake and eat it

I'm pretty sure Samsung does a fake-out like this to display your 80% charge as 100. (Samsung.tablet at least)

  The phones display 100% at like 98-99%. The Android API allows you do get the voltage and current of the battery (with negative current for discharging and positive for charging), so there are apps out there that tell you the real state of the battery when it's in that range. The phones will tell the user fully charged before it's actually completely charged, but it's not much. It's mainly so if you leave it plugged in, it can cycle a bit up and down while still displaying 100% instead of continually trickle-charging. My guess is tablets would be similar, but I've never had one.

    It's best for users that UI never displays true SoC(state of charge). They will not understand that the cameras and NFC payments don't work under true 10%, your degraded battery cannot safely reach nominal 100% voltage, etc. Those are not pleasant facts that users need always be made aware of. 98% understood by BMS rounded up to 100%, actual 12% displayed as 1%, etc., should be tolerated.

  Samsung phones stop at 85% and show 85% (if you enable the option "only charge up to 85% in the settings).

I would be unhappy if my phone has 20% battery left but I can't make a call or check map/WhatsApp.

  I kinda meant on the top end (So it never charges so high that the battery experiences increased wear). But... this happens at the bottom end too, your battery already still has some charge left at 0%, the BMS protects it from being fully discharged. I'm just wishing there was a bit more so I don't have to make decisions about wearing out the battery faster. Then I could enable OVERCHARGE and get 120% charge for travelling or when I know it's going to be a long day, at the cost of battery life.

  iOS already does something like this. After the phone turns off from low battery, it’ll still allow you to use Apple wallet for a few hours.

    It's a bit similar, but it sounds like that's less than 1% of the battery. I already expect my phone to die fast when it gets under 5%.

They almost certainly aren’t driving them to 100% physically possible, just like they aren’t draining them to absolute zero. The cutoff points are going to be picked to balance lifespan and capacity.
