Hacking CFW = Poor battery life?

[spinal_cord]

Is it just me, or does running a CFW (rxTools in my case) result in ridiculously poor battery life? It's all fine being able to boot (semi)directly into CFW but if it comes at the cost of my battery lasting less than a day while doing nothing with the lid closed, I don't seem the benefit.

I noticed it too, but maybe I'm not a good judge because my 3ds sometimes instantly powers off when I press the start button and the flashing red low battery light will come on after a full charge.

i feel like longer battery life than using sky3ds

I have the same experience. I highly thinks that the culprit is your wifi turning on + massive number of boot on/off hence juicing out your 3ds battery

I experienced it aswell, but no power on/off, just making it stay in sleep mode between plays drains the battery in ~2/3 of a day

Is the power light fading? If not, it's not going into sleep mode.

Is your system running a game in sleep mode? I haven't experienced any battery drain on my system. Perhaps your battery could be going bad?

If you're using emunand mode, yes, the battery life will drain out more quickly compare to normal mode because the system keeps reading and writing data to SD card. Turn off the system when not using unless you really want to.

I just used sysnand cfw mode and thats it, never used an emunand and my battery was fine, until my 3ds got bricked when i hardmodded it... the battery is on my table here and its still fine

Sp it takes more power to read/write to SD instead of NAND? I wouldn't have thought there'd be much difference.

In my experience, battery drain in sleep mode with CFW+CIA and no CFW+normal cartridge is the same.

Do you use EmuNAND? It depends if using system NAND or emuNAND is it the same for you?

Of course it is fading

It will take that much power if the SD card is power hungry

SD Cards have small processors inside them. They can be very power hungry if you get a cheaper brand.
