Virtualization will be coming to GrapheneOS

Tried userlnd and some other options, but the DEs and distros offered are a bit meh. I would hope for using Gnome when VMs are available. But yes, good if you want the linux environment and not the graphical experience. An interesting effort would be to have something like an alpine for running in the VM. Fast, efficient, lots of optimizations for working in low resource embedded systems.

The holy grail would be for the phone to be the computer. Dock it to use as a desktop, unplug it to go mobile.

Desktop mode is actually very close: Android 15's latest QPR beta makes your Pixel Tablet more of a desktop than ever before - Android Authority

I remember reading it will support phone display + 1 monitor as of now. Not too much, but 2 monitors sound nice.

MicroSD sounds interesting. What do you usually use it for? I try not to use on device storage and instead utilize network and cloud storage more. And most modern devices have good storage options.

Exactly. And this would be huge for affordable privacy too. Not everyone can afford to buy a enterprise laptop, or have multiple devices that they will need to upgrade after a few years. Pixels have long support, and cheaper compared to any secure phone + PC setup. Again, I do feel GOS has done enormous amount of work for everyday user privacy, without sacrificing much usability and fancy features. This is another feature for bringing privacy to the masses.

I love building PCs but laptops is a gap. Framework is working on this but the systems just aren’t that reliable. I would really like if there were a laptop chassis that docked your phone

Read the shared link for a bit, and am slightly confused:

  1. The DoD figure clearly shows keeping battery high (at 100%) increases the charge cycles the battery can do. Isn’t your point just straight up wrong according to your source?
  2. Seems like a personal attack, assuming their level of knowledge. Same could be said for you, and your source proving you wrong seems to solidify that belief.
  3. Modern phones don’t overcharge their batteries. Source: Literally any credible source. Here is one for you: Does a Smartphone Charger Stop After It's Full? | Sciencing
  4. Slow charging and fast charging seem like bad terms to use anyway. Your source again indicates that Constant Charge, Constant Voltage is what actually determines how charging affects batteries, and I can see 100s of papers on how USB charging protocols negotiate to provide CCCV conditions. The only downside cited in your source is actually temperature. It also calls it an environmental factor. Charging speed doesnt seem to be the culprit.
  5. Wireless charging does generate extra heat, but again modern battery management systems can mitigate this. Source: Is wireless charging bad for smartphone battery health? - Android Authority

Expected better from a community leader lol. Please read the sources before citing.

Edit: Mod removed the next post from me where I cited exactly where he is wrong by quoting his source. Nice power trip. Hopefully @jonah sees this abuse.

Look into nexdock, although I think better vendors will emerge when this becomes more mainstream, especially since Samsung dex is already a mature-ish product.

You got everything I said wrong:
-you didn’t understand the DoD graph, it shows literally the opposite of what you just alleged
-there was no personal attack
-I never stated that modern phones overcharge batteries
-slow/fast charging has nothing to do with the CC/CV phase of charging only with the amps/time that get sent into the battery
-any excess heat is bad for the battery and the way wireless chargers “mitigate” this is by stopping the charge once a temperature threshold is reached

Read the BU article again and take your time to fully understand it before alleging that I didn’t.

No, it’s not.

This article isn’t written by akc3n, which is noted here: Battery Management | akc3n's page of notes

Just because the phone reports the battery to be 100% it doesn’t mean that it’s true, modern phones have protections.

When the phone reports the battery to be at 100%, the battery itself isn’t physically full because it would indeed be bad for the battery if it was fully charged or overcharged.

When the phone reports 100%, it bypasses the battery and just powers the phone itself, so charging the phone to 100% and keeping it plugged in is the best for battery health.

It doesn’t matter if that heat doesn’t reach the battery itself.

Yes it is. The closer you charge to full the more stress it puts on the battery, the faster the battery ages and the less cycles you will get (keeping the battery at a high state-of-charge for a prolonged time is also bad).
There’s a graph in the article I posted that shows this in detail:

The phone misreporting the actual charge level by a few single-digit percent is irrelevant. And the heat does reach the battery, it’s only ~1 mm away from the heat source.

I think this is enough off-topic for this thread now, if you want to please DM me on Matrix and I will explain everything to you in detail.

Android 15 qpr1 will have an option for limit charging at 80%, so I guess it’s useful.

https://9to5google.com/2024/09/13/android-15-qpr1-limit-battery-charging/

To speak to the idea of running all of your desktop tasks on your phone, Samsung DeX is a thing and I think it has been for a while. It seems like Google is currently exploring something similar with the windowed applications. Samsung currently gives you a desktop experience if you dock your phone, so this does not seem like a stretch at all to one day have your phone be the only computer you use for most things.

I think all the battery health stuff is getting fairly off topic, but as far as I can see, what @Valynor is saying is really pretty foundational, broadly accepted, “101 level” lithium battery chemistry knowledge that shouldn’t be controversial.

Its hard to comment on the credibility or accuracy of the ak3cn gist because the author projects confidence but cites no sources, gives no facts, figures, or charts, and gives no credentials to help readers assess the credibility of some of the unconventional assertions they are making. (and the comparison to 2005 era batteries is a bit of a strawman, the author also contradicts current conventional wisdom, about current lithium battery chemistries)

Some Specifics & charts

Holding a lithium battery at 100% SoC is harmful to battery health regardless of DoD[1]. For long-term storage most lithium battery manufacturers I am familiar with recommend ~30-60% SoC.

Cycling your battery up to 100% isn’t great but also isn’t horrible, holding your battery at or near 100% is worse (if it’s lithium, if it’s a lead-acid car battery the opposite is true).

having too low of a DoD

That is a factor also, ideally you want to avoid both extremes (the upper and the lower ‘knee’ of the voltage curve). Both things are true and independent of one another. These are just two of the web of factors that can effect battery health.

Figure 8 shows that for the same depth of discharge (a very healthy and conservative lower limit of 25% SoC), healthy battery lifespan is significantly reduced when charging to 100% compared with 85% or 75%.

It isn’t shown in this chart, but in general, even just slightly modifying charge/discharge cycle bandwidth to something like 95-5 or 90-10 can really extend battery health over time.

Not sure how this became a battery thread lol

Yes but based on my own knowledge.

But people here seems to be eager to swap their PCs with this.

I have used Screencast too. But I have no idea regarding using a VM and then using via monitor by docking. My assumption, resource heavy and would kill the battery sooner if no powerbank is used.

Using a Dell Laptop, can’t cap by battery like that.


Offtopic question : Does GOS use Nearby share with Google account if Sandboxed play services is installed and your account is logged in ?

The best way to preserve your battery over the long term :

  • Avoid recharging above 80%, except for long days

  • When your battery drops to 20-25%, avoid going any lower and start recharging.

  • Avoid excessive consumption, especially when the temperature rises. The battery hates high temperatures.

I’ve never heard any such advice to keep your phone plugged in at 100%; all those who have studied the subject closely have given the same recommendations above.

In addition to the stress induced by recharging and parallel use, which can cause the battery to heat up more easily, when you will need to unplug it for a few hours (to go outside, for example), you could lose battery power much more quickly.

For bast’s sake, someone split this thread, @jonah - Could ya ?

The whole battery problem wouldn’t be a problem if they would still make phones with easy to replace batteries. Changing the battery on a Pixel 8 is “Difficult” and takes 1-2 hours according to iFixit
