Phone Chargers

What's the deal with phone chargers these days?

I see lots of these "fast chargers" these days with high amounts of current/amperage.

How does this affect the life of the battery? Are these chargers memes as well?

Who is this

Not memes but they do make your battery die faster

it's me, your brother

>What's the deal with phone chargers these days?

i dont give a shit

these pics are NSFW

fuck you op

Its a dude

B-bro?
Looks like I will have to visit your room tonight, don't mind the lube

Real fast chargers have two modes, one 5V/~2A and one usually 9V/~1.5A. When the phone is using the fast charge feature it charges at 9V, otherwise at 5V.

At normal charging phones should really not be charged at more than 2A, less is better if you want to extend the life of the battery. The 9V mode likely shortens the life even more.

Are you browsing Sup Forums from work?

WTF is this shit google?
That girl is not white nor naked

Something is wrong with your Google or you shooped that picture to imply that gooks are white. Mine says "asian bikini".

NSFW

you can thank me later

Not shooped, mine comes up with cute white girl naked too.
Both searching the thumbnail and the full image do.

OP here, it's Fumina Suzuki.

I don't know how fast chargers work with battery chemistry the thread.

godspeed, op.

Well, here is what my google thinks.

After a few tries it displayed "asian bikini" instead. And then after few more it went back to japanese. Spooky.

her clothes are undersized and/or Asians don't make stuff large enough for her. not complaining, but it looks like she'd have some serious marks if she wore that regularly

I read that in his voice kek

>What's the deal with phone chargers these days?

No way... Did she even do that scene with a "fan and a foreigner"?

So we've lost Maria Ozawa and Anri Okita now, fuck

obviously not
don't tell me you fell for that whore's sweet talk marketing

>sweet talk
I never really listen to her, just watch her get railed. Too bad then, that's a fantasy which kept me up many a night.

'fast chargers' just provide more amps, and sometimes a USB controller since some phones get autistic if you just give them 2a straight to the +5v line
My lg g4 will only fast charge if I use the cable it came with. Even if I use a cable rated for 2kw it my charge faster than 500mA

is she the same chick that was in this jav?

a battery can charge as fast as its capacitors can discharge

this is why the graphene battery meme will never be anything unless the capacitance is REALLY fucking huge.

Fast Chargers just up the amperage which in turn ups the wattage which if your phone doesn't support/can't handle will either burn your battery out or cause a figre

And tits feel like a bag of sand, right?

I would berry my nose up in that crack

thats her natural skin color, you fuckwit. only islanders and southeast asians have brown skin

This is how it works: batteries on phones charge by having a higher voltage than what the battery has being applied to them and a certain amperage being applied to them as well.

Normally phone batteries charge with a voltage of ~4v and an amperage of 1,000 mA. Assuming a 3.7v, a 3,000 mAh phone battery (typical on many smart phones) was being charged with a 1,000 mA charger it would take about 3 hours to go from 0% to 100%. This is also the phone assuming the phone is turned off and battery temperature is under 100°F (~38°C).

So what ends up happening in the real world is your phone will use about 100 mA of current (0.4 watts) per hour to keep itself in standby mode with the screen off. The battery is already competing for amperage and will charge 10% slower due to the phone being in standby mode. Temperature will also affect how much amperage the battery will pull from the socket. Greater than 100°F (~38°C) temperatures threaten to reduce the battery's lifespan or if extreme enough, kill it. In an attempt to save itself your battery will reduce amperage to under 500 mA of current or less when it is too hot.

What this means is for a typical smartphone a 2.1A charger is very beneficial because as long as temperatures are not too hot the charger will provide the battery with a steady 1A charge and you will have 1.1A left over to use your phone while it is charging. You will be able to play angry birds/snapchat or whatever and your phone will still charge in about 3 hours despite you using it.

However battery charging tech has come a long way and most phones have quick charging technologies that basically let phone batteries pull more than 1,000 mA and/or 4V out of a charger if temperatures are low enough. This is why say the Zenfone 2 will go from 0 to 100% in less than 60 minutes (requires 9v 2A charger and low temps ofc).

>japanese professor at my university is as brown as a latina

The amount of current drawn is dependent on the difference in voltages between the source (charger) and the sink (battery). The charger cannot push more current into the battery than the battery draws. The charger may be able to supply up to 1,000mA but the battery will draw only such current as the difference in voltages requires.
The charging current usually starts out high, assuming the battery is flat, and the exponentially falls as the difference in voltages drops. This is mirrored by the battery voltage rising.

idk what you fags are doing but my G3 with the 6000 mAh battery has been rape.

maybe it's that i actually don't use my phone like it's plugged into the wall and have a job that requires me to not be a leech on society by doing shit instead of getting paid to read Sup Forums?

don't get me wrong, i do read Sup Forums at work sometimes.

tl:dr - get a bigger battery, stop being a faggot.

Same

>tl:dr - get a bigger battery, stop being a faggot.
That's not the solution at all. Instead get a phone with super fast charging like the Zenfone 2 (under 60 minutes) and charge your phone when needed. It also helps that the zenfone 2 has an x86 processor which is more energy efficient than ARM. Sadly stock ROM is a little bloated and you void your warranty if you you unlock the bootloader (which you can) to install a custom ROM.

Excuse me but sexualizing women is not a good thing, you should all apologize and delete those images RIGHT NOW.

>The amount of current drawn is dependent on the difference in voltages between the source (charger) and the sink (battery).
lolwut? No, the current draw depends on how much the battery pulls (temperature affects this) and how much the phone itself pulls. The charger feeds the phone and the battery which is why a phone can survive without a battery and only a charger.

>The charger may be able to supply up to 1,000mA but the battery will draw only such current as the difference in voltages requires.
True but usually it will draw up to 1,000mA from 0-80% and as long as temperatures are not too hot. I think there is even a point where a battery will outright refuse any current at all if the temperature is too high.

Too busy fapping fuck off

We don't sexualize them, they do that themselves. Do you think they held her a point blank range with a rifle for that photo? She did this.

...

It wasn't bait, user up there is that delusional. But like I said women sexualize themselves. It's so funny how most people don't seem to comprehend this.

...

no, it IS the solution.

how fucking dense are you? charging isn't always a guaranteed way to keep a device functioning.

you sound like every fucking >25 year old girl that comes to work for me, wahhh, where can i charge my phone?!?!?!?!

meanwhile i have a damn near fully charged phone all fucking day and never have to worry because, worst case scenario, i can just swap out my battery with another one.

which never happens because the extended battery is so good.

idk if you're as retarded as these dense females that just let the screen burn when it's not being viewed or what.

been using my phone off the plug for 22 hours now and i'm at exactly 70%. the last hour i was dicking around reading Sup Forums on full brightness further draining it.

fast charging is cute but as with displacement, there's no replacement for mAh of battery life.

Got Zenfone 2, can confirm.

>how fucking dense are you? charging isn't always a guaranteed way to keep a device functioning.
True but having a 6,000 mAh battery adds weight which isn't ideal for a phone meant to be portable and light. A 3,000 mAh battery is already kind pushing it.

>idk if you're as retarded as these dense females that just let the screen burn when it's not being viewed or what.
Look, you're fucked either. Either you have a 6,000 mAh battery that weighs like a ton or a quick charging 3,000 mAh one that weighs less.

>fast charging is cute but as with displacement, there's no replacement for mAh of battery life.
Bigger batteries add weight to phones which causes wrist strain and other problems.

We're not addressing the true cause of battery drain here: the processor. The reason why phones have such shitty battery lives is because ARM is a cheap piece of shit that requires more electricity to run the same tasks. We need the latest Core-M processors in phones to take advantage of how energy efficient x86 truly is. Android can already run on x86 it doesn't give a fuck so it's not like the switch to another cpu architecture would be a problem. Sadly this may never happen since phone manufacturers care more about profit then a good product.

>no replacement for displacement
Except forced induction and modern hybrid tech and a well engineered engine that won't blow up after 2 laps

What's the SoT like? Also doesn't the fast charging thing reduce battery lifespan?

>cause wrist strain

holy fuck this made me laugh. What kind of limp wristed faggot are you? Jesus christ.

i found the faggot that not only doesn't lift, but never lifts.

if adding a couple ounces of weight ruins your whole experience you are a dandy littly bitch and need to go over to /soc/ and tell them how much of a weakling you are.

then there's the turbo faggot who has never done a trackday in his life and can't comment on jack shit based on feel and feedback on turbo cars vs n/a cars of similar times because he's a spec fag who thinks only numbers matter and doesn't consider the physical world.

i consider the physical world and if that faggot can't can't carry around either an extra battery or an extra thick battery then he should just shut the fuck up or fuck off for two hours while his shitty phone charges back up because he has no fucking real world application in life aside from using his phone. we got by without them before, and we can certainly get by without his type of faggot now.

It's about ergonomics not strength you fucking half wit

I have a naturally aspirated car and I've tracked it

What really cracked me up is that you think more horsepower from an NA motor somehow equates to better driver feedback on a track, instead if you know the actual fucking car

It's about not using your phone to jackoff to animu and being so pathetic it causes "wrist strain". Do some wrist curls and never again complain about wrist strain in your life.

What the hell do you do on your phone so much that you have to be constantly charging it?
Can you really not get off the Internet long enough interact with actual people in the real world and let your phone rest and last all day in a charge?

>exercising just so you can use a giant phone all day without rest
Wow, now that is sad

this lmao

>>>/RWBYtg/

>thinking that a 6000mah battery is heavy
>thinking anyone that doesn't have late stage ALS would get "wrist strain" from a fucking cellphone

Kill yourself you thin skinned cuck.

If you're going to be browsing Sup Forums all day, why not use a tablet of computer instead?

you you'd me wrong, i wasn't

>you

grabbing at straws.

now you have to tell me what your turbo trackday car is.

i'm waiting to see some dragstrip time slips as well. you do keep those, don't you? just to show you've got an 11 second civic right?

Why though? Just so you can shitpost on Sup Forums all day?

Why not quick charge your phone when you're not using it? Or when you're driving?
That's what normal people do

>trips
>normal people

holy fuck it is summer isn't it???

why not just use your phone without the screen on all the fucking time and get a phone with a big battery?

oh, right.

>normal plebs

Alright you got me, here's my turbocharged 11 second Civic

hehehehe

7/10

boxer fag but i don't believe it

show me some times, some 14 second quarter mile times.

That wasn't even me. You talking about wrist strain from a fucking cell phone hit me somewhere deep though. I just want to punch you in the chest ffs.

Fucking kek

Wut

I don't drag race roadsters, I'm not on Mighty Car Mods

>working

Your google is broken or you look for cute white girls too often and it's tailored to you.

Here's what I get.

So much cringe in a single post. Sick civic bro, vtec 4 lyfe

>quarter mile times
Spotted the boomer

This isn't OP girl

more like spotted the faggots scared of drag racing.

look i know you fags are new, but i've been doing this a long time and even a toyota camry owner should know his 1/8 or 1/4 mile time and should know what his car can do, within reason.

if you're that much of a pussy just fuck off. without acceleration you could be a fucking train and corner on rails, wouldn't matter if you're slow.

Okay.

>weeb's_wet_dream.jpg

Do cars like this trigger you? Does it upset you know that it's faster around tracks than newer cars with twice the horsepower?

>inferior 3DPD
>weeb dream
lolwut?
