Hello,

I've been poking around PineBook Pro for some time, and one of the issues is the battery charging current, which is way too low at slightly under 3 A at 5 V.  It even gets ridiculous, e.g. the battery pretty much never charges back to 100% once you try to recharge it from an empty state while still using the PBP.  Not to mention that the battery discharges when running higher CPU loads, which is both ridiculous and very bad for the battery life.

So, I took some time to investigate the PBP's wiring diagrams, trying to isolate the culprit.  In a few words, the good news is that everything points into that increasing the max. battery charge current should be a relatively easy mod.  It could even be incorporated into the next revision of the main PCB.  The bad news is that a mod like that must be discussed first.

The PBP's battery can easily take up around 5A during the constant-current part of the charge cycle, which is according to its data sheet.  The PBP's battery charger IC is configured to think that the system current is always zero, which means that only the max. charge current needs to be tweaked; again, this is according to its data sheet, page 17 in particular.  The PBP wiring diagram, page 11 in particular, shows the way the BQ24171 IC is configured, as already described.

In a few words, increasing the battery charging current to 4A would be pretty simple; all that's required is to replace the R44, R45, R47 and R48 SMD resistors, so their values configure the BQ24171 IC to take 4A from the charger (IACSET) and output 4A (ISET) as the battery fast-charge current.  Of course, any chargers providing less than 3A could not be used any more, which would render the factory-provided barrel-type charger useless; however, I don't think anyone would complain.

I cannot see anything that would prevent this mod from being successful.  The PCB traces designed for 3A can easily handle 4A, which isn't a huge increase of the current.  Maybe the F1 fuse would also need to be replaced, but I don't know that for sure because its max. current isn't available from the wiring diagram.

Thoughts?

so i didn't changed my pinebook pro OS so i still using Manjaro.
but the problem is that i can't install torbrowser. i tried to install a few versions and i got 2 errors:
Tor Browser requires a CPU with SSE2 support. Exiting.
and
Wrong architecture? 32-bit vs. 64-bit.

i think it's possible to install torbrowser correctly. i justs don't know.
can someone help me?

I have just reached Concept Proof state with AV streaming (calling) console client via Gstreamer with Matrix signaling. It works in both directions Pine to Pine and Pine to Element (web client). The SW better fit SXMO project philosophy. While streaming AV with other client on another PC it consumes on PP only around 35% of CPU.
For those who is interested details follow.
Monitoring part is based on matrixcli. Unfortunatly, author still didn't reply to my patch. Until then my fork could be used https://git.sr.ht/~fedon/matrixcli. It provides chatting functionality as well. For placing and accepting calls https://git.sr.ht/~fedon/gst-matrix. Python3 is required. Gstreamer with plugins could be installed form standard (PostmarketOS) repositories. It seems gstreamer-1.16.2-r2 has all required fixes. For desktop you better compile from Git 1.17.2.
Unfortunately, there is a glitch in Gstreamer which cause random hang during the first second of streaming. Patience is needed

Hello, I apoligize if this was asked before, but I wanted to ask again since it is in reference to new hardware and software.

For the new Pinephone (Community Edition: PostmarketOS version)  will a standard keyboard work with a USB A to USB C converter? I just wanted to check before ordering the converter itself. I ordered the $150 version since it meets all my requirements otherwise. If not, it's no big deal and I'll get used to typing with onscreen keyboards.

Hi All: Do you have an ST-Link or Raspberry Pi?

Here's a simple Bash Script that flashes the latest Community Bootloader (MCUBoot ported by me) and Firmware (FreeRTOS ported by JF) to your PineTime...

https://github.com/lupyuen/pinetime-updater

This is the very same bootloader and firmware that we are asking Pine64 to preload at the PineTime Factory. (Thanks Pine64! We   You   )

So go ahead and flash your PineTime now... For that Fresh From The Factory Feeling

I see there is a reset button by the battery pack on the inside of the phone.  Silly question, but will resetting the PPhone 64 wipe the OS?   I have the Ubuntu Touch on my UBPorts version.

There is data analysis sotware which runs under Linux, but do not run on a ARM based processors. Matlab and Bitalino Open Signals are examples for this. Are there any plans for a Pinephone which is based for instance on a Intel processor?

Hey guys,

it is already the second time that I experience this. I want to update with

Hi all,

are there any compatible repos to install PlasmaMobile instead of Phosh? I really like Mobian but I'd prefer PlasmaMobile to Phosh.

Thanks!

I don't know if this is occurring on the UBports end of things or the carrier end, but this is a somewhat concerning security bug.

I can send but do not receive SMS messages, I'm on dev channel, up to date as of today. I've filed a bug on that elsewhere. A couple of times a day I message my wife to see if she gets mine and to see if I get her reply. I never do. Today, I messaged her and she replied to the received message. I did not receive her reply, though her iPhone noted that the message had been received. She then got a message saying "Who is this?" to which she responded "It's your wife," and then a reply back saying "Huh?"

I did not receive any of her messages, nor did I receive any of the replies to those messages from whoever was sending them.

About 20 minutes after that, I DID receive a text message. It was an automated message from Venmo (or purporting to be so), with a 2-factor authorization code. That is the only text message I have received in several weeks. I have never had a venmo account.

My wife is using an iPhone, recent version, never has had any difficulties with SMS.

Can somebody explain to me what is going on, and how to fix it? I mean, like ASAP? I have no idea how much of my data is being compromised.

I am, to put it mildly, a little bit freaked.
