Long rant ahead. Should take about 2-3 minutes to read. So feel free to refill your cup of coffee and take a seat :)

It turns out that the battery in my new Nexus 6P is almost dead. Well not that I didn't expect that, the seller even explicitly put that in the product page. But it got me thinking.. why? Lithium batteries are often good for some 10k charges, meaning that they could last almost 30 years when charged every day! They'd outlive an entire generation of people!

Then I took a look at the USB-C wall charger that Huawei delivered with this thing. A 5V 3A brick. When I saw that, I immediately realized.. aah, that's why this battery crapped out after a mere 2 years.

See, while batteries are often advertised as capable of several amps (like 7A with my LiitoKala 18650 batteries that I often use in projects), that's only the current that they can safely take or deliver without blowing up. The manufacturer doesn't make this current rating with longevity in mind. It's the absolute maximum in current that a given battery can safely handle.

The longevity on the other hand directly depends on the demand that's placed on the battery. 500mA which is standard USB 2.0 rating or 1A which is standard USB 3.0 rating, no sweat. The battery will live for at least a decade of daily charges and discharges like that no problem.

But when you start shoving 3A continuous into a battery, that's when it will suffer. Imagine that your current workload is 500mA and suddenly you get shoved 6 times that work upon you. How long would you last?

Oh and not only the current is a problem, I suspect that it also overvolts the battery to maintain a constant current all the way till the end. When I charged my lithium cells with my lab bench power supply, the battery would only take a few milliamps when it got close to the supply voltage. Quick bit of knowledge: lithium cells are charged at constant current first, then when the current drops below that, it continues at constant voltage - usually 4.2 or 4.35V depending on the battery. So you'd set your lab bench power supply at 4.2V 500mA. But in that constant voltage mode, as the battery's voltage and the supply's voltage equalize, the current drops because the voltage difference becomes lower. Remember, voltage is what causes current to flow. Overvolting at the supply to stay in constant current mode all the way till the end speeds this process up but can be dangerous and requires constant monitoring of the battery voltage.

So, why does Huawei and a bunch of other manufacturers make these 3A power chargers? Well first it's because consumer demands ever more, regardless of the fact that they can just charge at 500mA for the night (8h of sleep) and charge a 4000mAh battery from 0 to 100% no problem. Secondly it's because sometimes you need that little bit of extra juice fast, like when you forgot to plug the damn thing in and you've got only 30 minutes in the morning to pour some charge into it.

But people use those damn fucking things even when they go to bed, making that 3A torture a fucking standard process!! And then they complain that their batteries go to shit?!

Hopefully this now made you realize that the fast charger shouldn't be used as a regular charger ^^

mechanical keyboard proponents be talking about longevity... I never ever had a membrane keyboard fail on me. they're indestructible. but I had a mechanical keyboard with kailh red switches fail on me, and I had to constantly spray it with wd-40 to make it work again. ugh.

you know what annoys me about this situation the most ?

noone is living an ideal life
in any sense
except a few

but that being said, living less than ideal life if people had not wasted so much time, would have led to certain things becoming better.

example.

if i was out of development work, and had to take a crap job.

and lets say that ended up putting me in a financially unstable situation.

if i had rotten teeth, i could work part time, go to a sliding scale place and fix them one by one
while either educating myself further or looking for a better job because in truth, if i'm accepting a part time job, i must be fucked.

i don't see any longevity in an intensely physical job, I see an early death.

there are not enough paying people to ensure everyone has a skilled job, and truthfully not everyone can, but we have more people than we need to do the unskilled and skilled jobs both so why are we not running with that ?

the best time to do unskilled labor or just labor jobs period is when a person is young and there body is new.

and then not for long or with accommodation considering throwing your back out or fucking up your knees stays with you for life.

everything is so backwards in this country.

people think in terms so frequently these days in 'how can i make someone else suffer for my amusement and see their potential diminished so i feel better about my fucked up pathetic life ?'

or

'how can i get revenge against a person that doesn't deserve it'

or

'how can i ensure other people are totally boned so my charmed life i don't deserve seems satisfying'

its pretty gross as are these people

well fast forward years later and life appears fairly repetitive for alot of people

took a very large of detours here, had some fun, experienced some fucked up horros, saw a few wonders which were mostly based off my ideas, and some that were not.

still i return to what is to be done about our unfair, wasteful system ?

I've always been a fan of removing people's 'excuses' to neglect their children for example.
and definitely blocking all avenues of abuse.
even unintended, or pretended to be unintended.
i also hate people who smell because they don't clean themselves, and use excuses for that
I also hate people who make other people live in a situation where they can't take care of themselves and then try to dominate places they seek refuge because our fucking system sucks.

I also hate that there is more food than people can eat and restaurants closing when there are hungry people.

i also despise that we have more vacant houses in this country than we have family units.
some are just rotting away from neglect.

and i most especially hate people who get off on watching whole landscapes decay.

there is tons of work for the proper people
some of it is hard
some of it is tedious
its these kind of tasks that are necessary
the right spirit and the RIGHT COMPENSATION and the work gets done.. hopefully.

starting out with placing everyone in means to eat and sleep and clean themselves seems the most important.

everything else is icing on the cake, because by and large many people get sick of doing the same exact things, and people hate staring at the wall.

the problem is, there are alot of people who are, due to extreme damages from our modified culture, extremely abnormal, sadistic and untrustworthy around... anyone.

so with more time on their hands, they get bored and turn destructive and antisocial and breed people to be worse.

years I've been preaching this.
same people fly past in man places.
here and there some new fool marches in, eyes sparkling with malevolence, only to get caught in the same eternal loop and be absorbed into it.
i haven't seen one such as myself that I know of, that showed up with every intention of changing their life, becoming friendly with people, finding the things they enjoyed, and improving themselves intellectually, emotionally and socially; searching for an environment filled with more people who would be helpful to this extent, getting a rude awakening and realizing how horrible their country was becoming.

don't know if I should be happy being alone as the only sane person. heh.

I really don't want to be. I just want us to be happy. this is deserved after so much hardship. after seeing how people in general have become.

oh we all have lusts and vices and shortcomings, but the gulf that had grown between ordinary folk and the general population is astoundingly wide.

Not a rant more like a question

Hello devRant,
I am currently planning to purchase a small home server + media client (with Kodi).

A small Linux Distro running the Hometheateroftware Kodi will run on the media clients (Odroid C2). The control is then over an app over the local network. The database of Kodi should be on the server in the form of a MySQL database. The movies, pictures, music are also streamed by the server (max. 2 simultaneously) via SMB (simplest variant). In addition, the server is to be accessible to the outside via a web interface to act as a cloud (maybe nextcloud). The whole should be optimized for stability and longevity. In addition, a small GitLab CE instance will probably run on the server. Do you have any comments or objections? The fact that I only take 2x ne 2 TB hard drive has the simple reason that I currently have no need for more space. Sometimes it happens to me that I forget completely obvious things :D

I've been an android/anti-ios person for around a decade and im now seriously considering switching to ios when the new iphones land. My mother is an apple nut and my brother is on android and everytime i bring up even the slightest nitpick about ios or macos (such as the fact that the "always use this application" checkbox on macos does not work or that you have to upload music through itunes) they jump on the "wtf then why would even consider it??????" train. In short its because ios seems at least a little bit more stable overall (havent had much experience with ios in general this is really more of a first impression). Well I got a replacement LG V20 just over a year ago and it has not aged well, had to replace the battery because i barely got 4 hours with minimal usage, even when i got the thing it was rather jittery, and its just now getting oreo (and surely wont be getting pie). Hell i was removing several apps earlier and it took a solid 4 MINUTES to uninstall an icon pack. After some investigation into the ios ecosystem i found that all the apps that i would need are on there so that was great. What im really hoping for though is some stability/longevity, im ok with paying around 1000 for a phone if it lasts a while and stays in decent shape. Finally the fact that the updates are sparing at best (with the exception of pixel phones) is a great annoyance whereas my mothers (around 4 years old) ipad is rocking ios 11. Could someone who has made the leap make a recommendation? I love android but i feel like all i would accomplish is buying another phone that craps out after less than a year.
