Battery Saver Mode

[nephalim]

It would be nice if you could use a battery saver mode... i.e. keep charge between 10% and 90% to prolong battery lifespan. There's no way to do this on Steam Deck right now, is there?

[Clone303]

yups there is no way, right now

[ReBoot]

The Deck already does that, it doesn't keep the battery perpetually @ 100%.

what reboot said is true, deck already limits your maximum charge after a while

This literally saves a negligible amount of battery life over the lifespan of the device.

Outside of, as people have said, it's already implemented like it is in 95% of other electronic devices.

It extends the lifetime of the battery by as huge amount, I have a laptop that has battery management built into the bios, it used to keep the battery between 20% & 80%
8 years old & I still use that laptop now.
Battery capacity is at 90%...
Dell Venue 11 Pro, Its got a higher battery capacity after 8 years than my steam deck has after 4 weeks

Dude, trust me.

Would love to have that feature! It doesn't seem to be present afaik.

If we can have some options and tweaks to the behavior of battery/power management then why not? You can keep using the default settings.

Because it's completely redundant since the hardware already does it. It's a waste of time to I implement.

Would be a highly sought after function for me. Maybe the Deck already charges to 95% maximum but displays 100%, but 95% is still too much for comfort. I'd like to be able to set my limit freely between 50% and 100%, or at the least a set limit at 80%.

Hardware (MAX77961) doesn't do that. Right now it charges battery to 8.7V (4.35V per cell) and just restart charging after voltage drops to 8.5V (200mV less). It is configured by Charger Restart Threshold CHG_RSTRT[5:4bits] inside CHG_CNFG_01 (0x17) register.
It should be possible to limit maximum charge voltage by Charge Termination Voltage Setting inside CHG_CNFG_04 (0x1A) register to for example 8.5V (about 92%) and restart would occur at 8.3V (about 85%). But I wander what would happen to battery capacity calculations.
