Battery life improvement

[freelectro]

Hi all,

I have bought my pinephone and use it daily.

I'm looking for better battery life.

The only way what i heard, it's reduce the power on time screen.

What can be a manner to have better battery life in general and espacially when the phone is on and active ?

What's the main difference with an android device !

For me, three component are main battery consumer.

1-CPU : Allwinner A64 4 x ARM Cortex A53 cores @ 1.152 GHz
2-Modem : Quectel EG25-G with worldwide bands


*****
1-CPU
*****
I have tried to power of two or three core -> no impact
not again tried to minimise frequency ! -> any feedback ?

The firmware is opensource ?

********
2-MODEM
********
The only thing what i can do is to flash opensource firmware of modem.

The opensource firmware URL : https://github.com/the-modem-distro/pinephone_modem_sdk


I don't know if this FOSS firmware drain less battery than stock firmware !

Have you a power consumption mesurement method ? It's powertop ?



I used this script to have notification with 3G/4G connection to keep connection with XMPP/Matrix client. And modem restart when modem disconnected.
