[Q] Battery Charge time - Galaxy S II Q&A, Help & Troubleshooting

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..

Ah forgot about that. But it's kind of pain removing that battery cover.

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%
sub 3 hours .
jje

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 -.-

Can someone please test the GS2 charge time?

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

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

Charge times seem to be getting really long now?

Mine has been taking forever lately, just took over 5 hrs to gov from 25 to 100%...WTF! My Hero with the 1500mah battery would charge from 10% to 100% in 1.75-2 hours this thing has a roughly 17% bigger battery but takes 3 times as long now to charge, it didn't at first when i got it but it is now no matter which of my 3 HTC wall chargers or my car charger I use. I don't know if the battery is going bad or what. Is there an app for displaying charging amps...I thought I read that there was but i can't find one?

I use Current widget (free in market).
Cool Thanks, wonder if that shows amps comming in to phone or just +amps over what the phone is useing...by the fluctuations I would say the latter. Works though.
That Current Widget worked great, when unplugged it shows draw and when plugged in it shows gain rate. Note for everybody, just because it sais its a High Speed 2.0 cable doesn't mean it meets the amp draw requirements. 2 of my skinny cable are only capable of transfering 500mah when the HTC cable and 1 of my thick ones transfer a full amp of juice. Good to know all my chargers work just have to get a thick-high quality 6ft cable now.

HTC Amaze 4G Taking 4+ hours to Charge

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.
Just charge it when you go to bed and you won't notice the time it takes

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.

[Q] Charging on the Samsung Galaxy S3

Well I bought the Galaxy S3 on the first day of the UK launch and depleted the battery to 0% then charged with the original 1 Amp charger from 0%. I had noticed that this takes a very very long time, around 8 hours. The battery life after charging however is substantial and very adequate.
On the second charge after depletion once again, I decided to use a Griffin 2.1 Amp charger which I had used to charge the hefty Galaxy note with. The Galaxy S3 charges at a much rapid rate and takes around 2-3 hours to reach 100% from 0%. However I have noticed that the battery life depletes a bit faster, Is this due to my imagination or is a 2.1 Amp charger not suitable for this phone as it was with the tablet-like Galaxy note.
Also note that I tried to charge my HTC one X with the 2.1 Amp charger and it charge very slowly, while the original HTC charger has a much lower ampage than 1 Amp
Hmm I have been using my galaxy s charger 0.5amp and it has been charging pretty slowly but seems to deplete faster.
I have been actively using for 50min on wifi now and 85% left. Which seems a bit quick for me. I will try charging with the standard 1amp tonight and see.
Now fast are you depleting at?
I measure my battery life by checking the screen on time just before the death of the charge which was 5 hours on the original charger, with the quick charger its 4 hours. My Galaxy note has no change in battery life weather you any ampere chargers. Also the general battery percentage seems to run low faster anyway on the galaxy s3 using the fast charger.

Just wondering, since the S2 had a limit of 650mA for charging, does this apply to the S3? You guys make it sound like it charges slow as well...
Galaxy s2 does charge very slow for me aswell. Compared to htc phones the Galaxy s 2 charges painfully slowly. Now I regularly use the 2 amp charger on my galaxy s3 and have seen a huge improvement in charging speeds. It charges at around 2% per minute and still lasts around 4 hours of screen time for a full charge.

You can verify by going into *#*#4636#*#*, Battery, using ori charger will show AC while HTC charger will show USB
I think samsung made some changes to the microUSB pinout

Thanx for the "shortcode". Where does one find those?
Also from reading about the MHL to HDMI cable from older devices not wotking, it does in fact seem that Samsung have changed the microUSB pinouts (although my Nokia 1.2A charger shows AC in that battery "menu").
Mine charges from about 10% to full in about two and a half hours, using the charger provided in the box.
My s2 came with a 0.7amp charger and took about 2.5 hours. My s3 came with a 1amp charger and takes about the same. Charges to 80% in no time and then slows down for the later part of the charge

A battery isn't like a fuel tank which you simply fill up through the hose until it's full.
Due to physical and chemical reasons, a nearly-full battery takes a lot longer to fill by a certain percent since it simply can't store the energy quickly enough.
Additionally, deep-discharged batteries often start with a slower charging speed (and then cranked up) to keep the battery from dying too soon and/or not being able to reach full capacity.
is the Nokia 1.2A charger ok to use with the samsung G3 as i got one of these spare and would prefer use it if so as the usb is way to short to reach from my desk up and around the back.
but the Nokia 1.2A charger lead is more than long enough
Just to check with all of you, i've been told that it is best not to charge your phone or any other handheld device IF the battery is not at a really low rate, at least not till your device actually prompts you to charge. They were saying that this would cause the battery life to be shortened. But at times, I need to make sure that i have enough battery to last me for a few more hours before i knock off from work, i would just charge the phone (battery at 25-30%) even before it prompts me to. Is it alright to do that often?
2ndly, at times when i stream videos on my phone for many hours, the battery would definitely drain fast and i would need to charge my phone at least 2-3 times a day. Is it alright for me to do that or am i "abusing" it? =X
Appreciate all your advises...Thanks in advance~
so any update on if using the nokia charger is ok with it being 200mah more than the standard 1A charger since it has longer lead.
or there is the 700mah samsung charger from my old S2

I don't know why this misconception still lives on; lithium ion batteries require no priming on first use. The WORST thing you can do with a li-ion battery is to fully deplete it before recharging. It is much better to top it off whenever possible; having said that leaving it turned on, on the charger once it is full is also not the best thing (though nowhere near as bad as depleting it fully).
I believe since this phone has a removable battery with external charger the best thing you can do is always charge your battery in the external charger and just switch out the battery when it gets to around 10%.
Nek0onna you should charge your phone whenever it's not full and you have a handy charger.

Can anybody check what the max charge rate is on this device with a battery monitor app? I have handfuls of 1A and a couple 2.1A chargers. I'd really like to charge at twice the rate if possible but not all devices support such rapid charging (kernel limits and such). Just curious before I buy one Thanks!
Even if Samsung slipped up and allowed a 2A charge i'd never want to try it, because tablet and laptop batteries are rated and manufactured for a higher current charge/discharge and most phone batteries would heat and swell up and possibly explode.
my HP touchpad charges with a 1A charger and it would be nice to use that with my sgs3.
Can anybody please check what the max charge rate is on this device

Extremely slow charging (12+ hours).

I recently upgraded to a Rezound before the family share data plans came around to keep my unlimited.
First thing I did when I got the phone was to install the latest ICS RUU, unlocked via htcdev, s-off and ra recovery. For the ROM I used business sense ics. Started on 5.4 and upgraded to 5.5. I'm using the stock kernel bundled with the ROM. It's running awesome. Only problem I have is the battery charging.
I have the OEM HTC 2750 ma extended 3.7v battery. The charging is extremely slow. It took the phone almost twelve hours to go from dead to "charged". I've read a few issues regarding this, but nothing that looks like it matches my issue.
Using battery monitor I checked the ma when charging and it seems to be charging at a slower pace than via even USB. It ranges anywhere from 175ma to 400ma with occasional jumps to 800ma and even the occasional dip into negative ma even with the charger connected. According to the app it seems to stall at 98% charged with a charge of 2692 mAH of 2720 mAh. I've tried the stock charger that came with it, an igo charger, an lg charger. Just about every charger I could think of. Even the 2.1 amp chargers.
Anyway, I'm at a loss. I love the phone, I just hate the fact that I have to basically be tethered to a charger for 12 hours to get a charge that only goes to 98%. Any ideas or explanations of to why this is happening. I checked the battery threads here, but like I said or doesn't really match my setup. I appreciate any input.

I know you have tried different wall plugs but have you tried different cables?
It is possible you might have got a lemon.
Yeah, I've tried a few different cables, even tried bump charging like I did with my old incredible. When you say lemon, do you mean the battery or the phone itself? everything is working so well except for the charging.

Does the normal battery charge at a normal milli amp rate or do they both charge slowly? Also, how hot is the phone when it is charging slowly? The phone might be getting too hot and slowing the charge down to reduce heat
Honestly, I haven't actually used the stock battery. I'm not at home now, but when I can I will switch batteries and let you know what happens.
The temp is usually in the low 90s when charging. It actually increases during use. Right now, discharging the temp is at 107 and seems to be climbing.

Try the stock battery. We need to narrow it down to a phone or battery problem.
install current widget
tell us what the mah charging rate
check ur cable might damage or fake
So I ran down my battery until the phone shut off today. While I was waiting I wiped the battery stats five times. I'm currently charging the phone now and it's charging much faster. The ma when charging now is up where it should be. Ranging anywhere from 500 when I'm using the phone to over 1000 when I leave the phone alone. I don't want to speak to soon but maybe everything worked itself out. I got about six hours of use out of the battery, and that was with the screen on over 90% of the time. Not bad. I'll report back after a few charge and discharge cycles.

Settings/Power/Battery Status. With the OEM charger and cable, it should say "Charging (AC)." If it says "Charging (USB)," there's a problem, with charger, cable, the jack on your phone, or the firmware you're running.
