Homebrew battery drains while in sleep mode

[psintek]

I've recently hacked my switch and I've been using an emmc to use atmosphere but I've noticed that it warms up and the battery drains a lot while in sleep mode.
The battery goes from 100 to about 50 in 4 hours.
My console:
Atmosphere 1.5.4
Firmware version: 16.0.3
I don't have Auto-RCM on or any sys modules.

Spoiler: Battery report

Does anyone know how to fix this?

EDIT:
After some time I discovered that I had the pins required to enter RCM still shorted, after Removing that the battery life came back to normal. Thanks everyone for the help.

I'm having the same issue now, it started some weeks ago, switch v1 unpatched. The detail i can add is that it ever hapoen with zelda botw or totk opened. I will full recharge now and see what happens letting it in standby without games running in the background

50% in 4h standby isn't normal.

Do you use Emunand?
Is it the same in Stock Sysnand (OFW)?

Hopefully only a software problem.

Disable all unnecessary system modules and you can try this config if you don't use the online service:

add it to atmosphere\config\system_settings.ini
It should help with power saving in standby mode.

Thank you. Something happened to my switch after updating it to 17.00. Something was draining the battery in sleep mode, it could drop from 100% to 20% over night. Problem disappeared when i put it in flight mode but that was just a workaround and i wanted a fix that not included a factory reset. Anyway, this fixed it.
