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.

You can try to recalibrate the battery, by doing the following

Charge it back to 100% (4.2V), then to 0% (3.2V), then back to 100%. Check note below
This will count as 2 full charge cycles and the % will probably be fixed on its own, or at least get closer to the correct one.

Note:
Mind you, that when you reach 100% it's not actually 100%. You need to leave it at 4.2V so it can saturate. Leave it charging for additional ~1-2 hours after you see 100% (time depends on the charger used).

I'm pretty sure it's not a problem with battery calibration, during normal use the battery lasts about 3 or 4 hours, something normal for a v1 switch. The problems only come when the console is in sleep mode.

Emunand would drain slighty more than sysnand CFW just keep that in mind if you are using one.

 

[swutch]

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.

[icemanx2]

had the same issue before, turning off and back on fixed it for me.

Something's not right as it's discharging at 600mA sitting in hekate, usually it should be around 200mA. Try to drain the battery completely in hekate and recharge it to 100%, repeat a few cycles and see if the problem is gone.

I occasionally get the same problem from my un-patched Erista, I leave the tablet in sleep mode while it's @ 100% battery, I do some chores like fix me some breakfast, shower then come back 2 hours later to find the tablet extremely hot with battery drained @ like 30%

I usually reboot by switching off for like an hour until the tablet is completely cool.
Temporary fix coz it'll overheat again after a month or so.

When I leave the house I make sure to completely switch off coz I think it's a fire hazard, the overheating could ignite the battery.

Hope you get a permanent solution coz switching off is a hustle to have to do the jailbreak over and over again.

@swutch is this a legit thing? do you got any source for this?

i have same issue.. v2, hekate, atmosphere, sx-core chip, sx-gear. (everything is latest 16.0.3)
and most of the time if i leave it on standby for a day, it drained the battery completely. airplane mode on doesnt helps. it also regularly unable to wake up normally. you need to force shut down and turn it on again..

is there any settings or i completely messed up with the files.

here's what i do whenever i update firmwares,

fusee.bin place in bootloader/payloads/
hekate_ctcaer_x.x.x.bin renamed to payload.bin (in root folder)

 

[garzacorporations]

The issue is mostly due to wireless signals (BT + Wifi + NFC), set console to airplane mode and you'll see battery drain is fixed and also hot console is solved. I solved both with this, now I only disable airplane mode whenever I'm going to use wireless, and even whenever I'm not gonna use internet I leave airplane + BT enabled.

Similar issue here, batteri went from 80% to 5% whilst playing pikmin 4 in flight mode. V1 with hwfly.

Your battery only have 80% of it max capacity, it would explain why it draining faster.

omg, give him back his 20% put it back!




Yea, perhaps he need to think about new battery.

Where are you seeing that exactly?

 

[runwave87]

Had the issue with lites/OLEDs mostly, the wifi was draining the battery while in sleep mode. You can go airplane mode, delete your APs or use emunand with HATS pack. Emunand and HATS pack has worked for me on all systems that had this issue

@runwave87 what is so special about this pack?

 

[Hayato213]

You have 3737 mAh as current full capacity, and the design was 4667 mAh, so 3737/4667 that is about 80%, what is your current now and average when it is discharging?

 

[ganons]

Ok so looks like it's showing the wrong information. This time when it came to 1%, I was able to play 1 hour of Mario Kart. Now I'm trying to fully charge and let it drain again.
