Doing some testing, here’s the idle battery life I can see at present: modem+wifi: 10:25 (Ten hours and 25 minutes) modem: 13:00 (Thirteen hours) Testing Methodology: Running a date script that wrote to a file every 5 minutes. Error potential: Only one sample tested for each testing type (I do…

Ok, I reset the L5 and repeated all of the measurements. I get a maximum runtime of 6 hours. :sob: I wish it was more but that’s the way it is

Is that with modem on and WiFi on? If so, 2.4GHz or 5GHz network? Also, do you have an SD card with a lot of files inside?

All on, display off, WiFi @5Ghz a SD-Card with normal usage (some music files ~200) - in my opinion a normal usage :slight_smile: Next I will look for the power guzzlers / resource guzzlers - let us see what comes up there. It is also possible that my battery has lost capacity.

Try with a 2.4GHz network - the Redpine card seems to be very power hungry on 5GHz for some reason :confused: I asked about SD card as there could be indexing going on in the background (and SD card access wakes the USB hub up which also eats some power) - it’s good to check it with tracker status. …

Okay, so…this phone still barely makes it through an average business day, and the primary hope is to get suspend working? Do I understand correctly that this would be like any usual PC’s suspend, i.e. the phone is doing nothing during that time? Or is it only certain hardware that gets suspended? H…

[image] Sebastian: Do I understand correctly Probably not. What this will basically do is what your current phone does when the screen is off. This phone is fully awake, although more and more sub-systems are in power-save mode when not needed, which already increased battery life over the …

The battery life issues on Librem 5 It is because L5 it using special security/pricacy/Libre Chipsets this chipsets are not optimized for phones, so Purism it doing all this huge work by optimizing these chipsets to phone, Battery life on L5 will be good on time. Big companies like Qualcomm the…

[image] Caliga: except for maybe the modem Even the modem could go into a sleep / lower-power state provided that it can wake up on incoming call, and then wake up the CPU - and provided that everything can wake up fast enough to take the call in time. However we are all speculating and this…

Battery life continues to be really poor on my Librem5 with Byzantium. This morning I used the kill switches to turn off both mobile and wifi/BT. Left phone at home with battery at 90% and went for a walk of no more than one hour. Coming back, the battery was at 78%. After another hour with all kill…

L5 arrived - Issues / questions Librem 5

I did another battery test today. Draining from 95% charge to 18% charge took 7 hours 45 minutes, so realistically about 8+ hours of “on” time. This was with mobile disabled in the settings, wifi on, and the phone dormant on the table, with just an occasional peek at the battery level.

L5 arrived - Issues / questions Librem 5

Today I did a similar test, this time on the mobile network, with wifi off. Over 7 hours, the battery drained from 93% to 20%, so again, about 10% per hour (10.4% in this case). The phone was sitting in two different places indoors throughout the day, with a strong signal in one room, and a weaker signal in the other. I was checking the battery level about once per hour, slightly more frequently than during my wifi test, and also opening the settings screen and browser a couple of times to conf…

Another Battery Test Librem 5

This time, I tested the longevity by charging to full, turned off all three killswitches, set the phone aside, then only activated the screen occasionally to check the charge (except when I was sleeping). The battery drained from 100% to 3% in just over 14 hours. My final check of the power level at about the 14-hour mark actually showed a remaining charge of about 35%, but that was apparently inaccurate, because a few minutes later I noticed that the phone had shut down. When I turned it back…

[MyL5] First Impressions of Evergreen (Tim's story) Librem 5

Nobody is working on suspend explicitly, but there have been some power management improvements lately that will also matter for suspend, for instance https://source.puri.sm/Librem5/linux-next/-/merge_requests/279 Personally I believe that it’s way more important to keep extending runtime battery life and treat suspend as the very last thing in the chain of things needed to be done for good power management. Suspend isn’t a magical answer to all battery life problems - if you need to suspend to…

Status of Suspend for Librem 5 Librem 5

That’s because that’s not the problem at all, just a matter of correct regulator configuration to not turn the modem off during suspend. The thing that would have to be done first is creating a branch of the ATF where both suspend and devfreq could work at the same time and this is the main thing blocking suspend to ram at the moment. With that in place there are several smaller issues like the dwc3 thing that will have to be debugged one by one.
