Battery Charging taking too long!

The S2 takes forever to charge the battery. Coming fron the iphone 4 i suspect this takes ay laeast twice as long to charge!
Considering the battery performance isnt that great, this is a double whammy!
What do you guus think?

Yeah, I noticed the same thing. I'm always charging it when I'm at home to keep it fully charged, in case I'm going out.

charging takes me about 3hours (from empty). It is stanrard time

Same here for charging. Between 3 & 4 hours. But battery life is getting better especially if i disable 3G and wifi

Im using nokia charger 1.2A and HTC charger 1A and also i have 0.7A all of them takes about 3 hours may be hardware bug?

I've been using a BB charger for it, and thought maybe that was the reason. Glad to know it isn't.

Yep, I confirm.
Charging takes around 3 hours.
I can use it almost 48 hours before it needs to be charged again. So it is not really annoying.

Stock SGS 2 with official battery charger and a full drained empty battery 3.5 hours to charge to 100% .

About 3 hours here which is fine, charging from the supplied charger connected to electricity mains. Are you charging via the USB connector? It will take a lot longer, something called trickle charge or something like that.

No it takes the normal time but if its to slow for you dont drain it or sell it .

I noticed this when my brother bought the same phone. His takes a ridiculous amount of time to charge, maybe 1% per 10 mins or so and it gets really hot while doing so.
Mine on the other hand doesn't get hot at all and charges at least 3 times faster than his.

please state charge state, ages, fast normal etc.
firmware and revison thanx

The charger shipped with my S2 has only 700mA...
especially if you are using the phone (worst: gaming) while charging it seems to get never finished . I guess the current drain doesn't left much for the charging.
So i'm using my old HTC-chargers (one AC=>USB and AC=> MicroUSB) witch both supplies 1000mA.... ~43% more in theory
Hard to say how big the advantage is in fact, but it makes a difference.
Also keep in mind, that a standard USB-Port supplies max. 500mA, depending on other USB-devices even much less. I also read that the charging result is "better" if you not using it in the meantime.
You can buy USB-Chargers up to 2100mA (e.g Amazon), but i have doubts that this will be improve the charging time because on the type-label behind the battery is written Rated : 3,7V-1000mA. Even more current wouldn't not damage the device (afaik!!!), the device or the battery could not charge faster.
Maybe somebody knows about what is meant by the the 1000mA exactly. Would be nice if the device could be charge a little bit faster.
Otherwise i am going to buy a 2nd battery with an external charger.
greetings

I found this on Android Forum

USB charging is slow on the S2 as it uses trickle charging
"Trickle" is an exaggeration.
The phone can tell whether it's connected to USB or a mains charger. If the latter, it limits charge current to 650mA. If the former 400mA.
It will charge faster on the mains but not loads faster.

I usually sleep more than 3.5 hours per day so I don´t see any problem in the charging time

My other cell phones are fully charged in 2 hours, more or less. And yes, I'm considering selling it, because I like to use my gadgets and the SGSII doesn't admit an intensive use without running out of battery, unless you have a second battery.

Yeah, I do sleep more than 3.5 hours per day and I try to charge it every night, but the problem is when the phone runs out of battery in the middle of the day and you don't have 3.5 to spend in charging it fully.

I think the iphone 4 is only a 1420Mah battery if I remember correctly while ours is 1650. Sure, it takes perhaps another hour to charge but I don't find it a big deal. It does appear that the first 50% charges faster then the second half as well but that could just be my imagination.
I have read that Samsung phones charge slower so that the battery life will be longer than that of those other phones such as HTC where the phone charges a lot faster. I'd rather get another year out of my battery and it take longer but do admit 3.5 hours does seem like a while.

this topic has been covered. teh SGS2 battery driver is capped at 650 mA for wall charging, 450 mA for USB charging. this code resides in the battery driver.
someone could compile a new kernel with this value raised. other phones like the nexus one charge at 980 mA for wall charger, 480 for USB.
samsung capped charge current, likely for heat issues, nobody really knows.

same. take long time to charge and heating if charge n gaming. the hottest spot at camera side

[REQ] SpeedUp charging process

Hi people... i think that Samsung has got a little of troubles of making batteries and charging philosophies.
I has got two devices that are the last technology from samsung, the nexus s and the galaxy s2 right now.
The nexus s has got a very strange trouble (until now not fixed) that battery never reach full 100% state in charging. And much very very long charging time.
The Galaxy S2 reach 100% but takes too much time to charge. It's possibile that never one has think about modifying this?
Where we can start to mod this ? Inside the kernel? Inside bootloader?
I think it's not only a mine trouble

i think its the battery charger not the phone, which makes it so slow

anybody know a program or a system commands that can show how much amp is going to battery?

5 views, 4 replies, justshows how desperately we want this...

Mine finishes very quickly. about 1-2 hours when it's at 25 percent. And you cant fix charging. Remember that it is a big battery.

Ever tried using an adaptor for a device that has a lower rating than the adaptor? Ever heard that pop and the smell that follows?
Learn to be patient. Last thing you need is for the battery to blow up and destroy your phone.
protip: turn off your phone while you're charging with AC and not USB.
it could be your USB (and by extension, your PC) is not providing enough power to the USB ports. It happens.
My phone charges in 4 hours with AC when the phone is off. 5 when on.
6 hours on USB, phone off. 8 phone on.

It can be "fixed" in the kernel.
Samsung made it charge slower so that it charges better.
Faster charging = more heat = more dissipation, and potentially other problems.

Even though its a safety feature, its ridiculously slow. Phones takes AGES for a full charge.

these new phone are strange
my old i8910 HD charges full in like 30 min
and stays without a charge for 3+ days

Mine charges slower than htc but no too slow.. I'd say 2.5 hours full charge

too much slowly. I prefer changing battery every 2 years but have a more speedy charging, specially when i'm in middle of day (usually i charge it in the night, but sometimes can't last the entire day)

Do you guys not get more than 3-4 hours of sleep?
Do you guys exhaust the battery to the point where the phone turns itself off before plugging it in?
Can you not plug your phone in before you go to bed?
I always plug my phone in before I go to bed (usually with 10-20% remaining) and I don't remember a time where I wake up in the morning and the phone isn't 100%.
I'm not trying to be cynical...just curious what other people's routines are when 3-4 hours to charge a phone becomes an issue.
A complaint like this wouldn't even cross my mind.

I need a faster charge too. Not because I'm impatient but because the phone can use more current then it can charge, especially during car navigation.

Well, the issue here is obvioisly not when sleeping (and yes I slept 3 hrs last noght and got a full charge...bit when on car or @ work, lunch time etc...those little precious weird moments u get in a daily basis when u arent using ur phone and got a charger at hand....maybe it would be possible to make an app which would allow toggling fast charging or slow charging, that way we could have both....fast ( on the run) and slow (night) modes....that would be really nice......but wait....winmo had this remember?

the device is getting hot while charged.

is this ok? happen to you guys too.
it getting hot while simple use sometimes is this ok?

Yeah mine gets hot too

It's expected, but this doesn't mean it's fine. It is due to the quick charging capability of the N6P, and this will shorten the phone's battery lifespan after a while.
If I were you, I'd use a "regular" charger when you're not in a hurry. For instance, my N6P stays cold when using my N5's 1.2A charger.

Interesting, thank you. I plug mine in when i wake at 6am and it's usually charged by just after 7. When i first got it, i was charging it all night, but realised i didn't need to do that. I'll dig out my Nexus 4 charger and use that occasionally for a slow overnight charge.

Actually, Google or Huawei or both of them f*cked all of us over because Nexus 6P does not actually have fast charging. A full charge to 100% takes about 90 minutes (which is pretty fast) but from 100% to full it takes another 30 minutes. So, it is kind of deceiving to max out to 100% fast and still draw power for another half an hour.

Any chargers with above 1000mA should be fine.
The stock charger is fast and phone get hot.

Fast Charge 4-5hrs?

just wondering how's everyone fast charge is, back when i had my note 7 it usually only takes an hr and 15mins for the phone to get fully charge, even in use. I'm currently using the stock charger and I'm not happy for it

Yeah....., did you plug it in and immediately take that screen shot? Are you using the stock cable with it? And lastly does it say fast charging in the notification bar?
Mine takes roughly an hour and a half to go from 20ish% to 100%

Your using the phone so the charge time hasn't adjusted. My Note 7 didn't charge in 1hr 15 min while I was using it.

My V20 charges crazy fast. There has been 2 times where It seemed to charge very slowly but I chalked it up to a likely bug or something. Other than those 2 times the device charges as it should, even when I'm using it providing the screen brightness isn't all the way up.

I will say if its charging slow make sure the usb end is plugged all the way in to the plug that goes in to the wall. I noticed this morning I was getting a slow charge and when looked at the connection it was not in all the way. Once I pushed it all the way in it started charging fast

As a v10 user I can tell you that sometimes (even using factory charger and cable) it doesn't go into fast charge.
Unplug it and plug it back in the lock screen should state "fast charging.." not just "charging.."

V20 doesn't charge as fast when using while charging. I am guessing that is a firmware thing or intentional to protect from heat, which I rarely notice.

that's understandable... back in note 7 it gets pretty hot but never exploded or smoked... but note 7 in use while playing a game will still charge the phone in 2hrs...
for me its a really big difference coming from note 7
thanks for everyone's input
using note 7 charger is actually a lil faster than the stock.... as far for my experience

Heating problem

Last night I've put my phone to charge until morning, and I've put the phone under a pillow because I have a one person bed and I don't want to hit it with my legs. In the morning, when I took the phone out....
The phone was extremely HOT! And I know where the parts are in this phone, and not the motherboard heatead up so much, the battery! I was so scared because this thing could explode in my hands or could've exploded last night.
Also, when I saw the phone the notification led was blinking blue, but after cooling the phone I couldn't see any notification. Is that a alert or something to say that your phone is hot?
I don't want to have a "note 7" clone when charging in my house.
I have this phone for just 6 months. Also the battery right now drops percent like per minute, really weak.
Does anyone had this problem too?

Here are screenshots:
Also, I am not using original charger because was too slow. I am using an 5V 2A charger. Now my battery stays at "normal" at 40C°
Is that normal?

I have found this in my manual. I will keep my eyes all day on my phone and will see if I will go to the service or not.
But I have bootloader unlocked, the phone was disassembled before, the water indicator is red, so I'm going to have to pay.

It happened to me. One thing I noticed that my phone was in wake lock. It never happened to me again. I think I was using LOS 14 at that time.

Every phone has heating problems. Few days ago i readed some articles and that stated: consumers should remove the custom cases when charging the phone. Do not keep your phone while charging on surfaces that stores heat (eg. your pillow), and try to not keep your phone on charge overnight. Even if its at 35-45% you should leave it so and wake up 30 min earlier every morning and charge again if you need more battery. 100% charge its not a good idea.
Remember you cant change battery easy, removing the back case its a pain, try to take care of your device, or you gonna buy a new phone soon

Of course not......You are using 2A charger.....It would obviously heat your device up
and yes ......2 A charger won't help with speeding up charging it would burn your IC instead..Your phone won't take in more than 1 Amp thats a factory limit and can't be unlocked without a custom kernel but still it's not safe.. Don't use that charger .....It's a placeboo that it charges faster ?
