Hi guys
I'm an iphone 3gs owner at the mo but my contract is up in a week and after doing A LOT of research over the past 3 weeks, i was pretty much decided that the GS2 was gonna be my next phone.
Then i foolishly visited the xda forums! lol (in fairness, it probably still will be my next phone).
But seriously though, setting aside the various issues some people are clearly having (reboots, battery drain, etc) what shocked me the most was hearing about the low-powered charging mechanism (apologies if i've gotten this slightly wrong).
I've heard that it only charges at ~650mah, but that the phone can easily surpass this under load (~850mah?), meaning that you could be charging the phone at the same time as using it, only to find the battery going DOWN. Can someone confirm if this is true? If it is, then i'm gobsmacked that Samsung could make such a c0ck-up. Imagine if you're using the GPS (a real battery hog) while driving (and plugged-in to the ciggy lighter) only to find that the battery dies before you get to your destination! lol. I've heard about the heat this puppy produces, i wonder did they limit the juice to stop it from burning a hole through the floor
Even though i'm bored to t1ts with my iphone (and i hate apple), what i love about it is that when i don't actually use the phone for extended periods of the day (which is quite often, due to work) it still retains it's charge really well (i get insanely good battery life). I would be really annoyed if i found the GS2 battery dropping any more than, say, 30% over the course of a busy working day (say 9am to 7pm) with virtually no use.
So, to finally get to my point! My iphone charges REALLY fast. I'm worried that it will take a stupidly long time to fully charge the GS2. Can some kind person please do an experiment for me, and see how long it takes theirs to fully charge (from fully dead to 100%) with the screen off and the phone not doing anything major in the background?
Also, it would be good to know how this compares to the GS2's competitors.
Sorry for the long post guys!
my phone is at 33% at 8:08
Will let you know how I get on. I have it on charge now
I think mine takes around 3 hours from empty using samsungs supplied charger but I will try to do a test for a more accurate time. How does this compare to the iphone?
Yep mine takes about 3 hours as well from empty to about 90% using the wall charger, then it goes on trickle charge the rest of the way. This is on standby as well.
Yepp takpes about 3 hours to get fully charged. however, i've been using the phone as a wifi hotspot all the time and yes, it increases charging time but it doesn't really matter when it takes so long anyways

65% at 9am
It takes almost 3.5-4 hours to charge it with stock charger from empty to full.
It takes a bit more than 5 hours to charge from empty full using USB charging in my laptop.
Found out the hard way:
Charging with original EU charger AND heavy use (downloading, Wifi tethering, map ops etc.) MADE it drain faster than charging.
Two nights before left it during night with orig. charger and made it in 8 hrs only to 84% while on.
With Hama 0,8 amps charger full in 2hrs from empty and stays full even with heavy work.
NO heat issue though !
Methinks the charger is crap

doesn't really matter which charger. got the nokia 1,2A charger and it takes nearly 3 hours as well to fully charge the battery.
I use my ipad charger with it and its definitely more like 2 hours not 3
My car usb adapter is 1amp and has no problem keeping it fully charged while using sygic satnav

Is this an ebay job to get one of these?
Any idea what the max amps the phone can take? I've been looking around, seen chargers up to 2 amps, but don't want to ruin the phone...
Edit: Sorry, posted too soon. Just saw this thread, and the battery has is rated at 1000mA, so ya, don't use a 2 amp charger

if you look thru the battery driver source code, samsung capped the charging at 650 mA it seems. not sure why, other android phones use the full 1 amp.
so samsung either saw a heat problem and lowered it, or that's just the way they do their phones charging. who knows.

Wow, ok. As someone who uses 3G a lot when our internet connection goes down (all too often), I hope the charge will end up keeping up with the battery drain. Otherwise I'll be tempted to change that source and probably end up frying my phone (if it ever gets in stock :|)
Thanks for the info

Guys my SGS2 is taking around 4+ hrs to charge from around 5% left. Is this normal.?
Yep takes 4 hours here too

What's the rated output on the wall charger?
I think this is by design as the phone already gets extremely hot when pushing the CPU (gaming etc).
I believe this can eventually be changed with custom rom/kernel.

5v @ 0.7A, by the looks of it this is normal.
thanks for responce peps. Never had a phone that took so long to charge.! Normally about an hour which is why i thought i may have had a problem with the handset.!
S2 stock Optus KE2 with it remained turned on with wifi, email checking etc using Energizer XP8000 battery as power source for charge went from 24% reminaing to 100% charged in ~2hrs. S2 internally seems to limit it to <700mah charge rate.
Find a Iphone4 charger or something similar it will give you 5v @ 1.0A, charges quite a bit faster, I use that at work then the slow .7 at home.
my XP8000 charges at 1000mah but S2 will limit it to 700mah
I think you could charge the battery alone in a dock. There it should load with the full 5V and 1ah..

Anywhere you can back this up? I seem to have faster results using a 1.0 vs .7, showing that it is getting more power.
It's been mentioned a few times across various forums. But i'm just going by my experience.
It also takes me around 4 hours to fully charge from below 5% battery. However, if I turn the phone off whilst it charges, goes slightly quicker. Obviously.
Hi,
I think the recharging time is quiet normal for such a phone (and battery).
I had to charge the battery of a friend's phone these days with my notebook.
And it took some hours from 30%. (HTC DHD)
About the same for my SGSII.
I think thats normal.
what would we do without electricity?
Dead phone that is fully discharged battery phone off stock charger to 100%

Changed handset yesterday. today charged new phone from 5% and it took 3hrs 4mins. So it looks like i may have had either a dodgy charger or batt.
I am charging with supplied charger(5V / 0.7A) ...
During the charging I turn off my phone but the charging time is still 3-4h -.-
I've had my new HTC Amaze 4G for 4 days now and absolutely love it, what a great phone! The battery life is great (I'm careful with all my settings) and I'm only finding issues with the charging TIME.
It's the second time I've charged it and after noticing how excessively long it took the first time, I clocked it this time and it took 4 hours and 45 minutes. I used a charger that I've used on many other devices with no issues (5 volts 1 amp).
The battery level increases 1% every 3 minutes, which adds up to 5 hours. I calculated this both with the screen on and by averaging out over a longer period of time with the screen off. I also tried with the phone completely off and the results were the same.
I made sure there were no processes hogging up processor time or excessive RAM usage.
When I go into to "Settings -> About Phone -> Battery" Battery status clearly states: Charging (AC).
I have also read somewhere that this can possibly be set this way by design (possibly to prevent the battery from heating or overcharging and saving its life in the long run).
I also realize that the phone is new, and the battery needs a few charges to be settled, but 5 hours to charge on the second charge just seems like too much.
On the HTC product support website, on the faq there is the following question/answer:
How long should it take to charge my battery?
"Your battery can take up to 4 hours to fully charge using the AC charger. It will take much longer using the USB as that is the trickle charge function."
Can anyone out there with an HTC Amaze 4G confirm how long their phone takes to fully charge from the AC charger?
I'm thinking/hoping this is a defective device/battery/setting...I don't like having to wait 5 hours to have my phone fully charged.
Thanks in advance,
Filipe
Ok, I'd like to add one more thing. I finished charging the phone last night (about midnight), by the time I went to bed (around 2 am), after barely having used it, it was still at 100%, now at 9:30 am (7.5 hours later) the battery level is at 95%. I had everything off and very little background services and apps running. Even the network type, is only set to the basic, no data connection was live/standby.When I check the battery status/histogram this is what I get:
-44% went to Cell Standby
-42% to Phone Idle
-8% Display
-6% Wifi (I think I used it before I went to bed, but turned it off right then, and it remained at 100% battery)
I'm not too happy...this can't be right...it shouldn't take 5 hours to charge and discharge this fast? Can anyone shed some light please?
Thanks
Come on....anyone? Please? This is driving me nuts!!
Yeah that sounds about right. Don't complain man. Your battery life is pretty good compared to other devices. My device takes 3 hours to fully charge and can last 24 hours with minor use. Just charge it when you go to bed and you won't notice the time it takes
My desire hd takes almost as much (Around 3 hours) and my Optimus 3d prolly takes even more (5?) to fully charge from a full discharge...
(With Stock HTC/LG Charger. The HTC's AC Adapter is 5V/1A [Shouldn't that charge a battery in under 1 1/2 hrs?]. Not too sure about the LG)
They take Much longer to charge on Computer/Laptop USB Ports. The Optimus 3d actually loses battery while charging (With screen on) with a USB port.
Also, 5% a night is pretty good. My desire hd goes down 3-5% per night (2g, no data enabled.) or 0-1% with Airplane Mode. (Rooted, Revolution 6.31)
And my optimus 3d pretty much runs out of battery in <100 mins with full brightness while Playing Games - It goes down more than 1% per minute depending on the game being played, especially if 3d Converter is used. This is pretty much the same for all GB/Froyo ROMs.

I Agree. Both phones usually last around a day at least for me. You could always try a battery monitor such as GB Battery Stats or watchdog (The CPU One). CPU Intensive applications and Awake time during sleep are usually what cause bad battery life. Faster chargers such as 2A ones should also charge the battery faster, but they might reduce the overall battery life.
I would suggest buying a wall charger and cheap batteries from ebay. They last almost as long as stock batteries and cost only ~$2-4 each. [They apparently explode though. Never happened to me.]
-------------------------------
Both phones seem to charge from 0-90% much faster than 91-100% as well. I'm not sure why, since 100-90 wastes just as fast as 90-0. (Charging from 90%-100% battery practically takes a third of the full charging time)
many thanks
RESOLVED (Sort of...lol)
Thanks for your feedback guys!
I just finished charging it this morning, and it's FASTER NOW!
Took exactly 2 hours and 37 minutes (Battery Moniter is a great app!).
I think it actually may be due to the phone having some sort of smart charging system which "looks after" the battery. Since the phone is new, it might be wanting to start it off with some slowww charges and gradually speed them up.
But I still have to narrow it down some more since this time I'm actually using the supplied cable and charger (the ones I tried before were also 5V/1A).
The cable I was using (had it for a while now) had a pinch or two, it didn't look that bad, but I'm thinking it could also be the cable (could be shorting)!
I'm gonna do some testing on this cable now and report back my findings!
Thanks again!
RESOLVED!!!
Ok, so it actually turned out to be the cable. I really feel like a dumb ass...lol. Oh well, at least I figured it out!
So yeah, one good way to see if your cable / charger is good is to use Battery Monitor, and on the main screen where it says your device is charging (AC) and etc..it will also say the actual amperage (in mA) being fed to the battery...that number should be within the 500 to 750 range, if its lower, there is likely something wrong. (Mine was at 16...lol).
Thank you all for your help!!
Cheers!

My problem was the cable, and it was causing the phone to take five hours to CHARGE, not discharge.
These phones don't hold charge for too long, and the more activity you got going on, the more power it will consume. The screen hogs up the most power, so using the device constantly (especially with high intensity background light) will drain the battery very quick. First smart move would be to set the screen intensity to the lowest setting. Wi-fi and bluetooth, if you're not using them, shut them off. Open your task manager (or get a decent one from the market) and kill all the apps you got running in the background.
Games also require a lot of graphics/processing power, so naturally they will drain a lot of battery too.
Edit: There are some special cases where it could also be related to your network or even simply coverage zones exposed to the device. If it's stuck in a zone where it has weak 4g and 3g signals, it will keep bouncing back and forth causing more drain than normal on the battery as well.
If you've taken all these things into account, then you may have a defective device, then you will want to setup an RMA...or just take it back wherever you bought it and ask to exchange.
Hope this helps,
Cheers
My skyrocket takes about 3.5 hours to charge from 10% to full charge. If I plugged it in the car charger and run google map with the radio on the background, it would slowly drain the battery even though it was plugged in. My iphone 4 did not do this. It charges very fast and does not drain the battery even when I had several apps running in the background. I think the skyrocket consumes more power whether it is plugged in or not.

Hi, what you need is a charger with a higher amperage rating than 500mA (or 0.5A). Buy a charger that is rated for 5V/1Amp like this one and your problems should go away.
The phone is basically "burning" more energy than it is receiving from the USB charger, hence the discharge.
To know the amperage rating of your charger look on the label for numbers that look like "5V/500mA"...
Hope this helps,
Cheers
EDIT: The link I provided does include an iPhone cable, but I'm just referring to the charger itself, the cable would obviously have to be a micro-usb.

thread moved to...mexico?
Most illegal threads are trying to move from Mexico.
But, you need a charging source more powerful then the base 500ma, (or whatever that term of measurement is) computers are only supposed to supply 500ma to a USB port so AC adapters are typically better for charging. But feel free to follow the post above and check the rating on the charger.

It will only charge when the screen is off, when I turn it back on the battery starts draining. Does anyone else experience this?

Yes mine does this too, i dont really care since my phone lasts 16+ hours i usually just start charging it when i go to sleep.
but yes i have this problem.
I just got my phone yesterday so I don't know how long the battery will last for me, but having it drain while plugged in is really annoying. I plug in my phone overnight and will read news and browse the internet until I fall asleep, so I don't want it to discharge while I'm doing that.

This does not happen with mine. I just ran a test - started at 82% on the wall charger. Currently tethering via wifi, doing heavy surfing. Also opened Opera and kept refreshing a page every 20-30 seconds to keep the screen on and to simulate surfing via the device itself. So doing double surfing. After about 10 minutes I was up to 84%.

My note charges while using it as well. The ipad charger likely won't make a difference unless the circuitry in the Note is different than the Galaxy Nexus as I tried an ipad charger with that and the current was so high it shut off from overheating..
Also your phone has software in it to prevent overcharging. What it does is it will charge to 100%, then even if plugged in run off battery power down to say, 95% and when it hits that lower threshold it will charge back up to 100% and so on. This is probably what you are seeing.

I've noticed something similar to this and attribute it to the dual core processor and movie-theatre-sized screen.
Actually, my Note takes longer to charge on any charger other than the one that came with the phone, unless I have it charging off a usb plug directly into my computer (for some reason). However, I will say that unless I'm doing something super data/GPS intensive like Google Nav, the battery will not continue to discharge while plugged in, so it's possible you might have a crap battery.
I would power cycle the thing a few more times and then if no different, try and swap out the battery.

Chalk me up on the list for those that have draining batteries while being charged. I don't even have to be doing anything on the phone except making a phone call... and it will drain.
I have a little update to my problem. Instead of using the cable that came with the phone, I tried a 15ft cable from monoprice that I had laying around. Now the phone charges when in use, and chargers much quicker than it did with the Samsung cable. So I am happy now.
I am having the same issue. It takes more than 15 hours to fully charge, then only get about 6 hours of usage. It will also drain if plugged in and I am using it with the screen on. This should not be happening. I believe that the battery is defective. If there is no fix for this, I am going to exchange mine. I read about the outstanding battery life on this thing and I want it! I was tired of getting only 6 hours on my Dell Streak and paid full price for the Note hoping to get at least 10-12hrs. I can't even get the thing to fully charge.

If you're using the stock charger and cable, something is wrong. Period. It takes maybe 5-6 hours to charge from nearly flat, probably less.

Using the stock charger plugged into a wall outlet? Or charging from a USB cable plugged into a computer?
in my experience since I got my note a month ago, different usb cables seem to vary in charging speed, even using the same usb port on my computer or the wallwart. I know that prob makes no sense and i can't explain it, but I have a cable that has those rf chokes on each end, and it is thicker than most cables, seems to carry current better or something. I am charging from a usb3 port on my desktop, and have fast charge turned on so that may be affecting it.
I can use my phone, while charging and I gain 1% about every 5 minuets.

I think I know what the problem is: Your phone is trying to kill itself and save humanity from that terrible font
seems like a bit much but it could be normal.
Once your phone's charge reaches 100% it stops charging to prevent damage to the Lithium-ion battery. I am not sure however when it starts charging again.
Mine charge % dips even when I am using plugged in! Horrible consumption with screen on.
installed only few apps.

Are you using the Samsung OEM home charger? It shouldn't be dipping when using that one. Mine will charge AND increase while using it in the car with GPS running (huge battery drainer) and a driving DVR program (DailyRoads Voyager) and the screen on. All with a car charger and cheater plug that shorts Pin 2&3. That's the secret to getting rapid charge to work. The OEM home charger has those pins shorted internally. If you are trying to charge over USB on your computer then again you need that cheater plug and ensure the USB port can support more than 700 mA. If it's a USB 3.0 port then it should handle that current.
No problems for me on the stock or aftermarket chargers with the screen on.
I have the same problem with my brand new I717 GN. Battery level slowly drops when on charge, even if it's the OEM wall adapter. I've tried my Kindle USB cables as well with about the same results. I noticed the charge is a bit stronger from the wall source, but still can't keep up with even simple web browsing via WiFi. I've installed JuiceDefender as well, and it's helped reduce depletion a bit, but not really enough. This phone would never last me a full day of intermittent use without a power source.
I've read several of these threads and there doesn't really seem to be a solid solution to this other than some GN owners saying they have the problem and some don't...
Someone mentioned a crosswired 'Smart Adapter Compatible with Samsung Galaxy S' on Amazon (I'm too new and can't post the link)... I might try that but maybe I'll return for a new one if some people don't have this battery problem, unless it turns out to be a latest firmware problem..?

he mentioned it and linked it 2 posts above you
ive thanked him, and guess about to buy
just that shipping cost more than the item itself, sheesh
I read an article in a journal recently about how smartphones charge their batteries. The article claimed that once the charge has reached 100%, it will stop providing current to the device until it reaches 90%, after which it will then trickle charge to maintain it at about 90%. All the while the battery meter will still show 100% (at least in the case of iPhones), but after you unplug the phone the first 10% will go rather quickly as it approaches the real charge level.
True for our notes? No idea. But with how Lithium batteries work, I wouldn't be surprised.
I haven't gotten my Note to discharge while plugged in with the OEM AC charger. In the car however, running Waze will suck the life out of it even while charging. (My car charger puts out about 150mA less than the OEM AC charger). Oddly enough, running Navigon on battery alone has less discharge than running Waze while plugged in...Which sucks, because while Waze has crappy directions, it has saved me many hours by routing around traffic. But at least the phone still charges while using Navigon and streaming some Pandora.
Why o why do samsung phones take so freaking long to charge? What good is slightly better battery life if the phone take so much longer to charge?
Yes I know S3 has 2100mah battery but it really shouldnt be taking over 2 hours to charge as phones like the xperia S and iphone 5 charge way faster per mah. Samsung has done a better job with charging speed than the S2 but still its behind.
I dont know why reviews never mention it? Its obvious cost cutting from samsung and trust me I am a big samsung fan but this is really disappointing and surprising that nobody complains about it.
I know atleast on my nexus S that it has nothing to do with the charger, the phone just wont charge faster no matter what charger I use.

Well first of all, most people charge overnight so its a non issue really. I dont get your issue with it. Maybe its not reported because no one cares about an extra half hour or so...
Secondly, if it charges faster, battery life will be decreased....also my iphone took longer to charge than my S3 does
Where's the obvious cost-cutting? Seriously, if people took the time to actually understand the technology they use, we wouldn't have these trivial misunderstandings.
Lot of people like i do charge the phone during sleep time, btw my phone charge very fast when i put on charger in daytime

Ya right as if no one ever runs out of battery before the night. And I like to have the phone by my pillow when I sleep.
And you must not be using a proper charger for iphone I assume?

My s2 has always charged faster than my old iphone 3gs, and is probably on a par with the iphone5.
The s3 seems to charge pretty fast. Stop plugging it in to your pc, it won't charge as fast on there
Having it by your pillow doesn't preclude charging it though..

I was using the charger supplied with my iphone.
Since this post, its taken half an hour to charge my S3 by 40%...
This is elementary maths. Charging a 2.1 Amp-hour battery at 1amp will take ~2.1 hours if there is no concurrent draw . I wish we could break the laws of physics and I bet Samsung wish they could too but since we can't I wouldn't let it bother me if I were you.

I dunno about the 3GS but the iphone 4 charges in under an hour.
And how come S2 has charged so fast? Using tweaked kernels? Well you see thats a different thing and not something every user wants to do.

So your S3 takes less than 1.5 hours to fully charge? I searched this and alot of users are reporting way more times and thats talking about the AC charger not computer charging which I know is slower.

I dunno what you are talking about. An xperia arc S with 0.7 amp charger takes only 40-50 minutes to charge a 1500 mah battery. It sure doesnt fit your criteria.
I don't see it as a problem myself.
If you find it troubling, why dont you try to set charge current higher?
Sad ...

Sad but true - with the exploding popularity of the S3 the forum seems to be invaded by script-kiddies without any clue
And another thing - if you recharge from an USB from a computer you will only get 500 mAh at most - so it will take 4 hours - but your S3 will NOT overheat and the battery will probably survive for twice more full recharges!
EDIT:
Some explanations for the script-kiddies and mactards without a clue (which if you look below you will see that is most likely trolling around):
http://en.wikipedia.org/wiki/Universal_Serial_Bus#Power
Also certain kernels - for instance Siyah - lets you tweak the recharging parameters - but that will not change the fact that standard computers will immediately disconnect your S3 when it draws more than 500 mAh, or that recharging at 1000 mAh will heat the battery / device and VASTLY accelerate battery aging.

mah = milliamphour (1000th of an Amphour)
An Amphour is 1amp for an hour so a 1 amphour battery will last 1 hour if you draw 1 amp. That is what Amphour means. When charging, the current drops off when nearly complete which is why I used the ~ as a symbol for "approximately".
It is simply impossible to charge a 1.5 Amphour batter in 40 minutes at 0.7 amps unless the battery is knackered and not fully charging.
I have no interest in arguing with you but physics is physics and the same rules apply to all manufacturers.

Again I dont see evidence for this. iphone has a battery capacity of 1420 mah so that means it should take around 3 hours to charge through USB when it infact charges in just over an hour even through USB.

Hmm letme recheck the xperia charger. You seem very knowledgeable and I have had questions about charging times for the longest of times and I really want to clear them. Will get back to you.

I believe some computer USBs can provide 1amp now.

I am talking about normal computers but just the latest ones. Dont know what apple does but every single android phone takes considerably longer to charge through USB.
Lol my S3 charges really fast compared to my s1&s2
