Another hot summer day is coming, but @williamtries you forgot to mention status of: WiFi/BT card, as related:
And it is way less about thermal paste (important factor but not the main/critical one within/related to the Librem 5), IMHO. It is about power supply (source) used over there as/while when the Librem 5 reaches 5.00V it stops charging its battery! Yes I still need some time to be 100% sure, but when the BPP-L503 under 50% of its rated capacity (4.20V related one) Librem 5 uses/recharges internally its battery with 4.75V (or to be precise compliant power supply or powerbank in usage outputs 4.75V, as I might show within another post of mine). Actually I’ve noticed this for many months ago but I was unjustly disregarding (ignoring) that fact (therefore this post of mine relatively late in time ):
With the WiFi/BT HKS off:
Also and if someone is wondering at all on why used tester is showing UNKNOWN
code/protocol (when WiFi card out of the related circuit) it is because BPP-L503 battery is out of the charging loop (just my guess, as of now) and Librem 5 runs purely from the attached powerbank. For those living within or not far away from Italy, like @fiacco, it is available from here: https://www.sbsmobile.com/ita/en/fast-charge/620-pocket-power-bank-8000-mah-lcd-8018417262241.html.
Yet I do not mind or recommend directly to take here presented 8000mAh one as it takes way too many hours to be recharged over its micro USB (input) port. Please consider newer generation ones, as much better choice (with upgraded but still compliant quality that your Librem 5 is desperately looking for): https://www.sbsmobile.com/ita/en/fast-charge/1662-fast-charge-powerbank-10000-mah-2-usbs-8018417293931.html.
As sbsmobile
shows us here: https://www.sbsmobile.com/ita/198250-thickbox_default/fast-charge-powerbank-20000-mah-2-usbs.jpg. 20000mAh one with the USB 1A
port integrated (+ USB-C input) is available for purchase as well, car chargers … (might buy one to proof that, but I do not plan to do this any time soon).
RELATED NOTE
: Preferably/only use, please, with Librem 5, USB-A output port in black (not the blue one) that is “marked” with 5V/1A. As I unofficially observed from my side USB 1A
output provides current of 4.75V/1.45A
throughout/when BPP-L503 under 50%.
NOTE II
: With the WiFi HKS off (meaning WiFi connected and in use) Librem 5 consumes more power when its screen off, as shown (in order to be compered with the initial, very first picture attached here containing word UNKNOWN
).
P.S. If someone wandering on why I wrote this post it is to proof that there are no heating issues in excess, whatsoever, if we are not (of course not) technically making Librem 5 “life” (when on) poor/misery! For example (as tip): recharge your Librem 5 battery when its capacity percentage around 40%−50%. Furthermore, someone might even leave it connected if 100% compliant power supply, like the Anker PowerPort Atom PD 2 − A2029, used after red LED light off (as this puts BPP-L503 battery out of power supply circuit, after 4.20V reached, please take a look at sensors
command output, as attached above, I think as no “tricks” over original PureOS installation applied, and therefore cannot overcharge it). Use only quality charging cables (even if there is no queue for the 24AWG/2C
ones any more), adjust “things” toward Librem 5 usage, not against it (or buy right away another smartphone ). And not to forget, I like my Librem 5 too (even more than yours)! Thanks Purism!
