I noticed that for my application(a Geiger counter) a Core2 uses 120mA from 5volt and drains a 2000mA battery in about 16 hours, But when I use the CoreS3 it uses 250mA from 5volt and drains a 2000mA/h battery down in 8 hours.

I prefer to use the CoreS3 (much better screen responses) and I can order them as CoreS3-SE (no back). But the double amount of the current drain of the CoreS3 is not acceptable for my clients.

Is there a way to reduce the current drain while keeping the CoreS3 fully functional?

I have the same problem. Trying to find a solution for the powering up from battery connect for my Geige Counter project https://bgeigiezen.safecast.jp). Originally I build the board for M5Stack Core1 gray and all worked fine. However, for M5stack Core Black, it did not power up from DC. Then I could not get Core1 anymore and started to use Core 2 V1.0 and that powered up nicely on battery connect. But Core 2 V1.1 does not do that, anymore. Still trying to find ways without adding extra components like a delay cap/resistor on the Enable pin to get it started.

Please check if you have a Core V1.0 (axp192 PMU) or a Core 2 version 1.1 (axp2101 PMU) For me a Core 2 V1.0 powers up from DC connect. But Core2 V1.1 does not.

On the M5StackCore 2 V1.0 by connecting the battery, it did automatically switch on. But on the M5SatckCore 2 V1.1 it does not. How to program the M5Satck Core 2 V1.1 to automatically power up from connecting to a battery?

Hi all,

I have designed a board with the M5Stack grey on it and the battery is a 16580. But it only chargers at about 120mA. How to set the IP5306 to charge at higher currents?
