@chdslv That doesn't make much sense. UT packaging uses click, not apt.
How does the system gets cleaned after app upgrades? Is that done automatically?
Anyway, I think a touch centered distro won't work with Dex. The device is supposed to work as a touchpad, when an external monitor is used. Don't know even, it'd get installed. Thanks anyway.
apt-keyis used to manage the list of keys used by apt to authenticate packages.
You can find UBports key at http://repo.ubports.com/
or should I do,
apt-key adv --fetch-keys http://repo.ubports.com/archive.key
or any other way?
For Linux on DeX, I presume you can simply add the UBports apt key and repo, and then install unity8, however it likely won't work, due to how things are built.
What is the Ubports apt key (where can get it)?
If I could do that, I wouldn't have asked the question.
It would be nice, if UBports can discuss the matter with the Linux on DeX developer team. I mean, if they agree, things would go forward on quite new devices. I have an N5, but it becoming just a toy now, mostly lying around.
Is there any chance of having Ubports or Unity 8 on Samsung DeX? On Linux on DeX? Ubuntu 16.04 is quite nicely working there. It is the only distro available yet.
@advocatux From the article you linked.
"That old saw about how you always need to charge you battery all the way up, and use it until it's dead? Memory effect, as it's called, affects NiMH batteries but it doesn't apply to your phone. In fact, you're phone's battery hates when you do that. Similarly, lithium-ion batteries don't need to be "calibrated" with a full charge and a full discharge when they're new."
"A lithium-ion battery typically charges in two stages. First comes the process called constant current charging."
"When the battery is 70 percent recharged, the procedure changes and flips over to constant voltage charging. During this second stage, the charger makes sure that the voltage—that is, the difference in current between the battery and the charger—stays the same rather than keeping the current constant. Practically, this means that as the battery gets closer to full, the current the charger sends into it decreases. As the battery gets full, the rate at which it charges slows down. Once you reach 100 percent, the charge simply trickles in, just enough to account for the tiny, tiny bit of charge your battery loses naturally over time."
Anyway, the 100% charge the battery until the icon becomes white is not exactly correct. Usage of the energy depends on how much the apps use them, over time. Apps use the energy they need, disregarding the level of energy in the phone battery. And a mobile phone sleeps most of the time.
Finding a fresh, new OEM Li-Ion battery for our few years old phone is pretty hard -- out of production for a year or two.
@lakotaubp I've been doing some research on the life of lithium based batteries for last few days.
They don't have any memory like effect as in the older Ni-Cad batteries. What might damage the lithium battery is dropping the battery charge to 0% and leaving it for long time. Charging it to 100% all the time only makes the charging cycles less. It is better to charge up to 80% to get more charging cycles from the battery. Short charging the battery also helps it.
When the mobile phone goes to sleep, some apps are still working depleting energy. If the phone is completely off, no apps are working, you'd get practically the same battery level the next day, when you boot it up, but that's not what a mobile phone is for. It should be on all night, all day.
@chdslv We are always here to help and assist where we can. However we will not allow the issues you have been made well aware of.
If you have another issue or problem regaurding Ubuntu Touch you will be welcome to post it on the forum. The Community is here to help.
Thank you for the help offer, that is, if I buy the OPO. N5 will be sold, so the problem is over.
Only, please understand, the OP is "Observations on battery life - please share your experiences" and I was writing about my observations and experiences on the phone that I own, not on other phones. I wrote about my "observations" before this thread.
Anyway, the N5 battery problems are over, at least for me. If I buy the OPO, and if I find any problems other than the battery, I'll ask. There's no need to antagonize anyone on something that can't be solved.
