The Switch 2 gets bigger than the Switch 1 and probably also needs a battery with higher capacity.

What ist your estimate (in Watt hours) for the Switch 2 to meet Nintendo's battery life goals?

For reference, here are the battery capacities of other handhelds:

It better be silicon carbon battery, then 6000+...

15 minutes. (edit: The motherboard already supposedly leaked, no? Do we not know battery capacity off this leak alone? Or is there a bit more to it than this? I’m not super informed on gaming hardware spec details…)

The motherboard doesn't show us, how much space is left in the case for the battery.

The battery connectors also gives no indication to the voltage. Switch 1 ran with 3.7 V, but I expect that Switch 2 needs 7 - 8 Volts, similar to a Steam Deck.

The problem with the battery is that those tend to get quite heavy the more Wh of electric energy they can hold. It's the main reason why the Switch is substantially lighter than Steam Deck, ROG Ally an so on. As such, I only expect a moderate increase to roughly 25Wh, maybe 30Wh, so similar to the OG GPD Win or Nvidia Shield, as otherwise the handheld would get too heavy for children to use over prolonged times without straining something.

Yeah, that's my estimate, too.

Keeping it at 16 - 20 Wh probably won't be enough, especially if the majority of rumours (8nm-SoC) are true.

Little kids with small hands will probably have to wait for the "Switch 2 lite" anyways due to the big SW2-Joycons... the normal Switch 2 seems to address teenagers and adults. Due to the huge Switch 1 library and probably a lot of cross-gen games, little kids will have to play their "Switch 1 lite" until then with a great selection of games.

The first revision in one or two years will probably "Switch 2 lite" with a die-shrink to 5 nm or 4 nm and a smaller battery to get the weight down.

Followed by a new revision of the standard model with the same 5nm/4nm SoC, which keeps the battery size and uses it for a longer battery life.

So it is a 5220 mAh battery (not replaceble by the user).

Does anyone know/heard how many volts the Switch 2 needs?

• with 3.7 V that would be 19.3 Wh battery capacity
• with 5 V that would be ~26 Wh battery capacity
• with 6 V that would be ~31 Wh battery capacity
• with 7.4 V (double of Switch 1) that would be 38.6 Wh battery capacity

Digital Foundry is expecting that the 5220 MaH battery has 20 Wh battery capacity and that it limits at 10 Watts in mobile mode in their Switch 2 video... so they seem to expect a voltage of 3.7.

I still have my doubts that the Switch 2 can be so much more efficient than Steam Deck & Co. to reach 2 - 6 hours battery life with a 20 Wh battery when the others need 40 - 80 Wh for similar battery lifes and ~20Watts for similar results.

So maybe their guess is wrong and the voltage + battery capacity is higher?
