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
Does anyone have any ideas on how to increase car charger performance?
When I am using Google Maps Navigation with the GPS running and full 3G signal, the phone barely charges at all. Depending on screen brightness it can actually drain the battery(slower than when not connected to a charger).
Can the charger be modified to increase its output?
You have to buy a charger, which has more than 1 ampere
I have the Brodit Active Holder w/ Cig charger, I'll have to check the specs on it later. Do you think it could be modified in some way?
I bought the SE car charger (http://bit.ly/k7udKw), the price was a bit steep (20 euros or so) but it works like a charm. I use Sygic Aura navigation and the battery meter still increases over time. Not fast, but it doesn't stay put or decrease either, so I'm all in all happy with it.
Check out this thread...
http://forum.xda-developers.com/showthread.php?t=1005618
And make sure you set your phone dock near the air conditional if you open GPS map, it'll get hot and your battery won't last long while it gets hotter even you charge it.
I bought my charger on Internet auction for about 2 Euros (some crappy China stuff) It works like a charm. And yes, battery gets very hot when I use navigation so I mount my phone holder near AC vents.
There must be a reason for the severe heat in the x10.
even in ultra low temperatures it overheats a lot.
So i finally remembered to check my car charger and it is a 1amp charger. I've just upgraded my rom to the one listed in my sig and the phone is much better on battery, so hopefully it charges better in the car now.
Had my phone docked in the car for 20minutes and it charged from 82% to 95% with the GPS on and Google Maps following my route. Pretty happy with that sort of performance.
Mines charge normally i use orginal se charger because in my car i got an ac plug

im using this one

it charge fast and it can charge another USB device like an iphone or my MW600 bluetooth... it can even charge my x10 to 100% while GPS navigation is on. my previous car charge doesnt do that, it can only hold my battery % without letting it drop if GPS navigation is on. so if my battery is 30% i'll get 30% after i disconnect and stop using the GPS navigation...

I've bought this one a while ago for 7 bucks (including shipping). Had just a few chances to use it, but all times it was really sunny and hot outside and the phone just stops charging because it becomes extremely hot. I would stick the mount somewhere near the gear stick, but it won't stay on any other surface than glass
It was a quite funny adventure when we were travelling to a big city with intense traffic and really complicated streets. So I am using the GPS to find the hotel we booked, it's really hot, I just keep going - didn't know that the phone stops charging when it's hot - so we finally arrive at our destination, I start to reach the phone with my hand and it just turns off, because the battery is dead. Was quite scary at the moment
Yeah, did some driving around this weekend using Google Maps Navigation. Had my X10 plugged into the charger that came with my Jabra Cruiser speakerphone. Despite the charging light being on the whole time, by the time I arrived at my destination my phone had >5% battery. I checked the charger, and it's only 500mA.
Ordered this charger from Monoprice.com (was ordering some cables anyway). The price was good, and specs say it outputs 1A. Will let you know how it works out when I get it.
Hi,
I'm having an annoying issue with my car charger. I'm actually using the SE car charger, the 1200mA one.
The problem is that sometime, the charger will charge very well, meaning I can listen to music, have the navigation active, and twitter, G+ updating as usual, the battery is charging around 1% per minute, but on other time, the battery will slowly drain, same setup.
I've noticed something yesterday btw, the phone was in a battery draining phase, then it appears that the phone lost his network connection, then it came back, and the phone started to charge well.
Is that an issue related to the car charger or could it be a "bug" in the phone software ?

The phone limits the charging current at a max of about 700mA.
Sometimes the radio eats thru the battery quite heavily in low signal area's.
The charging current just plainly cannot keep up with the total usage.

You can try that.
In some cases it works in other cases it does not.
I have had my X10 for nearly 2 years now and i have tried about 5 different car chargers until finally settling on a SE original.
I use my x10 with google nav all day long as i am a service engineer and i have found the only way to get it to work for a full day is to mount it directly infront of one of the air vents blowing cold air over it while plugged in to the charger. Without this the phone will get too hot and start discharging especially on a warm day.
Using 2g and low brightness can help as well.

LOL. The X10 was released in late March 2010. So unless you had an early development model, you've had your X10 for 16 months at most.

Yeah, I learned how crazy heat will build up in this phone if using it for nav a few weeks back, when in about 75 minutes of driving I drained my battery fully and the phone was registering at 54°C from sitting on my sun-beaten dash while navigating.
I thinking I'm going to try to build some sort of shade over my car holder to keep the X10 out of the sun, and maybe help channel some of the AC more directly onto it.
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.

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.

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..?

ive thanked him, and guess about to buy

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.
Hi everyone i have been using wifi 5.0 about 3 months now it satisfied me enough and i am sure will continue. But the only issue which makes me unhappy is when i am gaming or using gps battery finishes rapidly. I would like to learn when to charge the device is 25% ok and when i am using it on charge even when its full is it bad for the battery life?
Yes you should unplug it when it gets full.

don't leave it on the charger longer then 20-30 minutes after it reaches 100%, any longer can be damaging to the battery if done repeatedly.
Wish these chargers were more like the motorola ecomoto chargers that cut off charging automaticaly once the battery hits capacity.

Thank you for your answer but every time i am charging it over nights i am always turning it off and go to sleep what i want to say i cant wait to be 100% then sleep is there any app to stop charging when its fully done. And isnt it ok while gaming o keep the charger cuz u know after playing 1 hour of fifa12 battery nearly going dead? thanks again.

So you mean this devices are not made for using on charge like laptops?

stopping charging has to be done within the charger itself, so no there is no app that can stop it, plus apps couldn't do anything when the device is powered down anyway.
An hour of a game kills your battery? I can play atleast an hour probably closer to 2 of angry birds and thats from less then 30% and i'm on the 4.0 player which has a much smaller battery, sounds like you've got some battery drain issues to work thru.

yeah u are right about apps no way any app to work when the device off.
I mean maybe 1h and 20 min. with 50% brightness on and i guess fifa use more data than angry birds when ur playing.
anyway its important to know that i shouldn't keep charger on when its 100% because usually when i am home i was using it like that thanks again.
do u think the app called 'sense analog' may make the battery life shorter.
Something is definately wrong, because I can play MC3, which is even more intensive the FIFA on my Gplayer 4.0 for more than 1.5 hours and still have some life left, and the Gplayer 4.0 is only rated for 4/5 hrs and yours is rated for over eight!
After a full recharge, while still plugged in download battery calibration from the market, and follow it's instructions, after you do, while STILL plugged in, reboot. After a full reboot, unplug it, and DO NOT REBOOT until your gplayer completely dies (forces shutdown). Once that occurs, plug it in, let it charge to 100% (while on), leave at 100% for about 15 minutes, unplug, and use as normal. That should fix your issue, unless your battery is dying, which should not occur, even if you are abusing it badly, for awhile longer.

haven't seen the 5.0 screen in person but if the brightness levels are anything like the 4.0 why do you have it so high? My brightness is at like 15-20% with autobrightness OFF.
First, like many others already said, it sounds like something is wrong with your battery. I'm on a 4.0 and playing two hours of a really intense 3D game with auto-brightness indoors will bring the battery from 100% to 50% (maybe it even uses less battery).
Second, as to how to conserve battery life, Rule #1 (as others have said): definetely do not keep it plugged it at 100% for too long. Then, something I tried on my iPod and have been using ever since: keep the battery between 50% and 100%, and once a month, completely empty the battery (until it shuts down) and after that charge it to 100% (this is called a charge cycle). As to my iPod's battery, before I was using this, the battery life got shorter and shorter, but after, it didn't shorten noticeably anymore. On the computer I'm writing this on, for a couple of months, I barely followed this plan, and I lost about 5% of my battery capacity (I have a battery widget that tells me what the total capacity is) within one or two months, but then I started following it a little more closely, and actually got some of it back. Over six months later now, I have lost about 10% of my battery capacity (from the original capacity), except that I should do a charge cycle in the next couple of days, and the last time I did a charge cycle, I got about 5% of the original capacity back, not to mention I have broken rule #1 probably too often and for way too long, often for several hours
My 5.0 can play games for hours before it dies but it has strange batery levels..From 100% to 75% it goes very fast.around 40 minutes when you play game..and then on 75% it stays there for 2hours when you play game and with regular use it can stay all day on 75-70% ..after that it fastly drops to 25% and just when you thing you need to recharge it can stay on 25% forever..you can play 2 more hours of game on 25% or with lighy use it will stay all day on 25%.

This is not correct. NO modern device has ANY smarts in the external charger - nearly all current phones (and every smartphone on the market for the past 3-4 years) has a constant voltage 5.0 volt USB input. Modern "chargers" are not chargers at all - they are dumb 5 volt power supplies, nothing more.
Charging "smarts" are handled by electronics in the device itself and have been for ages. (For all practical purposes, the Player 5.0 is a Galaxy S smartphone minus the cell radio...)
The kernel and charger hardware automatically handle charge termination and restart themselves. This is, for example, why Daily Driver can charge at higher current levels than stock at low battery (but drop the current as the battery reaches nearly full in order to stress the battery less).
Oh, as far as battery percentage display - the method used for estimating state of charge on the Players is abysmally primitive and highly inaccurate.
Battery Charging YP-G70
I always charge my completely standard YP-G70 overnight. As I understand it, the charger only provides voltage and in this case it's 5vdc. The device's battery management software draws the required current to charge the battery. If you install 3c's "Battery Monitor Widget Pro" you can see a charging graph showing the current levels drawn over the full period of charging. The charging current is stepped to control battery temperature and is reduced as the battery approaches full charge. By the time the battery reaches full charge the current draw is down to a trickle charge and will not overcook the battery. I usually leave the device switched on, which further protects it by maintaining a small load. One of the problems I have found with this device is that this charging regime, along with the fairly large capacity of the battery, mean that the battery can take up to six hours to fully charge, which confirms, in my view, that overnight charging is OK.

First of all thank you for this valuable information, thus I can keep my device on plug while i am driving and using gps otherwise on long distance its annoying to keep checking the battery while driving with gps app on.
Other think is i guess its normal but just to ask, The device becomes really hot on charging while i am gaming. What do u think?
Is there an app that takes time of your battery like today I turned on at lets say 7:00am and the battery dies at 9:00 and you forget the times but the app says how long it lasted. Is there some app like that?

3c's "Battery Monitor Widget Pro" gives all the battery information you could ever need. A data log and graphs allow performance to be analysed over any period of time. You can set markers to indicate charger plugging and unplugging times. Hope this helps.

Off course it will be hot..you play game which hots cpy and gpy and at same time you recharge batery which hots battery..but if battery reach 50 degrese celsius player automaticly stop recharging no matter whow much battery is full.

Gaming = CPU and GPU cranking at full tilt with the display on - of course it's going to get warm.
