What's Everyone's Battery Life?

[RxBrad]

After watching @wermy's videos, I was kind of expecting around 4hrs. I just went 2hrs on a fresh charge (with audio over the speaker) before @Popcorn's low battery script shut off my GBZ.

Parts:
- Pi Zero
- This 2500mAh battery
- The BW version 7 screen
- This USB hub
- Generic Arduino Leonardo Mini board
- PAM8403 Amp with PWM Audio (Pi -> PWM circuit -> amp -> pot -> headphone -> speaker)

What's everyone else seeing?

4.5 hours on 5000 mah

Hmm. That seems in line with mine. Weren't you using a Pi 3 though? My build has a Zero.

[Chedda]

I have a pi0 in mine right now. I have multiple builds going. 1 completed and they guy hasn't picked it up yet. I've been playing with it myself.

It would be nice if everyboda who replies with his/her battery life could post a link to the specific battery.
thanks for everyone wo does this ;D

before @Popcorn's low battery script shut off my GBZ.

Can you link to that? Ive seen his hardware version, but theres a script to shut it down?

[RxBrad]

@Frodowills Here's the link. Camble's shutdown switch uses a modified version of this script (which is what I'm actually using).

EDIT: Yes, as the post below this one states.. you need both hardware and software for the shutdown switches.

It sounds like you're misunderstanding. The script is meant to be paired with the hardware. Without the hardware the script is useless, and vice versa. Camble's board needs both hardware and software as well.

@RxBrad what did you end up using to monitor low battery, popcorns circuit to red led or cambles LBO diode?

On a side note my battery is a 2600 mah that fits in battery compartment without having to modify it and I get around 2 1/2 hours out of it.
