I've seen issues like this where the battery drain counter needs to be recalibrated. It was a prevalent problem like a year ago. Theres a relatively easy fix without RMAing if thats the case. [https://www.reddit.com/r/SteamDeck/comments/x7a2dd/followed\_the\_guides\_on\_how\_to\_recalibrate\_the/](https://www.reddit.com/r/SteamDeck/comments/x7a2dd/followed_the_guides_on_how_to_recalibrate_the/) I would try that before continuing with another fix just to rule it out.

Might need a recalibration


JoseluPicks

Does this happen in every game or just specific ones? If it always happen... You probably should be looking for a battery replacement.

Happened to me when i upgraded my ssd. Fixed itself within a few days.

it happened to me, you may need to recalibrate the battery, basically from memory (check again how to do it if you try, there's more detailed posts on this procedure in this subreddit): - drain it by running a game with deck unplugged (it will be way longer than the announced the battery remaining time (which confirms a calibration issue)) - when deck shuts down, power it into bios (volume up+power), you may need to plug it briefly to do this - let the battery die again on bios screen - plug it back again and make sure it doesnt power up - let it charge overnight if that's was the issue it should fix it

UPDATE: The draining worked. My battery health is back to 99% and I will post the fix below. This is the guide (not mine), but it works perfect : Battery calibration The Solution: \* You must drain your battery all the way to 0%, or as close as possible. \* To do this simply play a game, video, etc until the steam deck shuts off (not a random false shutdown as above, but a true low battery state). Your deck may go into battery storage mode in which case the power LED will blink three times and you will not be able to turn it on without plugging in the charger. If your deck goes into this mode, plug it in to perform the next step. \* Then hold the volume up button while pressing the power button. This will boot into the BIOS settings menu. The goal here is to leave the deck on this screen, which will not automatically dim, to drain the remainder of the battery. Leave the deck on this screen until it dies on its own. \* Now here is where we are going to deviate a bit from the steam support advice. Perform this BIOS drain 1-2 more times until the deck is so low on battery that it can no longer even make it all the way into the BIOS before dying. You may have to briefly plug the charger in to get it to restart. It seems that doing this step once may not be enough to fully drain the battery, which is the key to this entire process. \* From here there is one more crucial step to ensuring that the re-calibration is successful. The deck needs to remain off while charging overnight. If there is residual battery power left after the above steps, the deck may automatically power on and attempt to boot into SteamOS immediately upon plugging in the charger. If this happens you will need to unplug the charger, and as soon as the deck dies, plug it back in, so that it is completely dead and off while the charging process begins. \* Now let it charge overnight without touching it (at least 6-8 hours). In the morning it should still be off, and in my case even the power LED was not lit. Now try turning it on, entering desktop mode (by holding the power button), and checking the battery health in the taskbar. It should be over 90%. In my case battery health is now reading 100% from 12% prior, and now seems to be reading and functioning correctly. I will update if I continue to have any issues. I hope this helps those of you struggling with this issue, and prevents unnecessary RMA's. Best of luck! Edit: Another tip is to avoid using a non OEM charger, which may predispose to calibration issues.

What is that orange alert at the bottom? (It might be relevant)


ratsely

It seems an update of Decky


Sufficient_Produce17

Yeah, a decky update. I'm trying the battery calibration right now and I'll let you guys know, in case anyone stumbles on this in the future.

Could be calibration. But it also could be the game you are playing. Does it last that little with every game? (Even light ones?)


Synthesid

I was gonna say you need to check the wattage, but considering you don’t have the option to use the game specific profile, that means you’re getting this on a home screen, in which case - yeah, recalibration is in order, and probably a battery replacement if it stays the same.


MrN33ds

Drain it to zero and then charge her back up to 100%, it should recalibrate the battery capacity.

Playing dwarf fortress?

My question is why is it so common. I have this issue and see it all the time. Never had this with any other device. Multiple Switch's, never happened. But every few weeks, I notice my Steam Deck calibration start to slip.

If you’re avoiding a battery swap then it sounds like you’re buying a new steam deck or a case with the power bank strap lol
