Battery Management on PinePhonePro: - d50zesl0g@mozmail.com - 03-01-2025
I’ve been experimenting with ways to tweak this. I’ve managed to set up a system where the battery cuts off from charging when it hits a certain point but remains available for discharge down to a lower threshold if the phone needs it.
Here’s how the scripts work under various conditions:
- Standard Charging: The phone charges to a predetermined upper limit (like 90%) and then stops to prevent battery strain.
- Continuous Power Supply: If it remains plugged in post-charge, the phone priorities drawing power directly off the charger, sparing the battery , and only use the battery if the power supply is not producing enough juice.
- Reconnection Nuances: Unplugging and replugging doesn’t immediately resume charging. It waits until the battery drops below a set lower threshold (say, 60%), which helps in maintaining battery health by avoiding short, unnecessary charge cycles.
- Handling Power Fluctuations: For those times when the power source is unstable or you’re frequently plugging and unplugging, the script ensures that repetitive charging doesn’t kick in unless truly needed.
- Customization: The thresholds for both the upper and lower limits can be adjusted to fit personal usage patterns and battery longevity goals.
Project Repositories:
For PinePhonePro: https://github.com/alivellani/manage_pinephone_bat_temp
Librem 5: https://github.com/alivellani/manage_librem_battery
On the PinePhonePro, managing this is pretty straightforward because the driver includes a ‘charge behavior’ driver that you can manipulate directly. For the PinePhonePro, you can find the charge behaviour control at this path:
/sys/class/power_supply/{battery_type}/charge_behaviour
The Librem 5, however, threw a curveball my way. It doesn’t support modifying charge behavior through the usual driver settings. The workaround I found on the wiki, using the charge LED as a control point. Here’s how I control it:
/sys/class/leds/chg_en/brightness
This lets me toggle the charging on and off
I have attached a Anker Zolo power bank to the back of the phone which keep providing power to the pinephonepro with a velcro tape. And I just charge the power bank.
Heads-up: This setup is still very much DIY. Make sure you really dig into the scripts before deploying them. If your phone turns into Charmander that is all on you!
Cheers!

The PinePhone and the PinePhone Pro have completely different battery control hardware. (The battery itself is the same, but that does not matter here. What does is the power management chip.)
The original PinePhone uses an X-Powers AXP803 chip for power management. The PinePhone Pro uses a Rockchip RK818 chip for power management. (I believe that the reason for the different choice is that the AXP803 is designed to work with Allwinner SoCs, the RK818 with Rockchip SoCs.) They are not compatible.
Your program supports only the RK818, and as such, labeling it with just "PinePhone" is misleading, as it will not work on an actual (original) PinePhone, only on a PinePhone Pro.

Well yes, but your link was prefixed with "For PinePhone:" before you edited it today, and the GitHub page you linked to does not contain the word "Pro" at all. Neither in the project name, nor in README.md, nor anywhere else in the repository, really.
