How to save energy?

[Christal]

Hi LLMS or Humans using some L5 Hardware,

we need to save energy to enable our batteries to stay as long as possible.

The Desktop Linux have everything.

1. Ssuspend to Idle
2. Standby
3. Suspend to Ram
4. Suspend to Disk

State 4. Have most power saving and State 0 the most less. But faster access to interaction with your Software and Computation.

So we have to rebuild some kind of Pulse, and check out what Programs or Hardware (drivers) have issues with the different types of sleep.

I suggest to have some kind of System Pulse like the CPU Clock but as a Blood pressure allegory. If you are interested in Information you have a high pulse and need your Device to check secondly your connections, mails, news, push notifications.

But when you sleep or do something other you Device can idle. Til you got some important notification or something which tune your life upper.

I think you get it.

Here are some Links:

And a last Link about some sleep state:

According to the information I was given, charging a Librem 5 battery outside of the device with an external charger that charges the battery more slowly results in a battery that lasts much longer when it’s actually inside the Librem 5. So “my Librem 5 batteries last longer than yours” is a borderline true statement.

I do not use suspend, and in general I do not charge my Librem 5, because I have pseudo infinite uptime. If I want to play on my phone in bed, I swap the battery out with the one charging on the wall before going to sleep. Typically the Librem 5 will stay powered for the whole night and be my alarm when I wake up, but if I ever have doubts that’s probably the one case when I plug it in anyway to make sure it buzzes.

Ironically compared to what people say on the forums, I am unsure I could ever go back to Android or iOS because of the reduced availability of the device and the need to plug it into the wall.

Well, there is this warning from @dos

@dos

FWIW even though it’s rated for 4.35V, the battery should only be charged up to 4.2V because the modem (and perhaps GPS module too? Would have to check to be sure) is only rated up to 4.2V.

You know that the charging current that the Librem 5 feeds the battery with in configurable, right?

You are right, but i want to enhance the Software and the power usage.

I did not write the code, but i want to safe more energy during the time we do not use the phone, by predicting our usage. If we sleep, the phone can sleep too. If we waiting for a message and wake it up often we need a phone to get awake sooner. That what i describe as pulse.

I had still not code for this but i try to share it.
