My X2's battery seems charging in eternity. Have it plugged almost half a day and still is charging. I'm always turning my X2 off when I'm going to charge it, so I can see the battery icon when it's full. But this one's crazy, when I turn on my phone and looked at how many percent that it has been charged...it says 100%. But then again when I turned it off (still plugged to a charger)...it's still is charging.

Same issue as mine. I wonder what's causing this?
dont worry
this is the problem that many of us are facing with.
no way to get rid of. phone jast charges till 100%, and illumination stops , but the status remains charging. but really its stopped. the charger and battery both get cool.
Had anyone of you did try to send it to SE service center to address this issue?
Many times when I charge the phone the % indicater will just stay at whatever it was when I plugged in the charger. If unplugg the charger for a few seconds and reconnect it again the % indicater will update.
It's just one of those bugs.....
l have contact SE about a month ago..still no reply

It's better to leave the phone on when charging, that way the OS itself can control power management.
Really though, don't worry about it... as it has been said... it's just one of those things

Thank you for that info. But, how long does your battery lasts? Mine wouldn't even last 24 hours.

This is a question that is very difficult to answer as it depends on which applications you are running and how you use your phone.
Earlier this week I experienced that the battery dropped from 100% in the morning to less than 20% around 5 PM after having used the phone quite frequently throughout the day.
Yesterday I used the phone very little and from 100% battery yesterday morning I'm now down to 59% after 26 hours of use.
If you want your battery to last make sure you:
- turn off the screen when you do not use the phone
- turn off WiFi and Bluetooth
- don't use the radio
- turn of GPS
Maby someone else have more tips on how to get the battery to last.
here issue is not standby of battery-it is simple charging time and unacceptability of x2 to stop charging procedure. it just go on and on with charging(it does not display when it the battery is full it display that it is still charging-even if the phone is on charger more then 10h!!)

Sometimes I can use it all day and still have somewhere around 40% to 60% left at the end of the day. If I don't use it that much, it will maybe drop 10% per day. I have gone 3 days once without needing to swap my battery.
I have a standalone charger and 3 batteries. So I swap out the batteries from there every time it is low. It could be possible that the standalone charger does a better job of charging to full capacity.
EDIT: I also leave my 3G on always!
My battery lasts 3 days,about 30min of talk every day,5-10sms,20-30min of wifi,3g is off,gps not using yet...so that is about that.

3 days? And mine was just about....damn!
I have had it plugged into the mains, running tunein radio through wifi and its gone from 85% to 86% in one hour.
If I charge from 10% with phone off it takes about 4 hours to fully charge
If I charge from 10% with my phone on running stuff, it actually never gets to fully charges by the time I finish work...at 6pm
Sorry to keep comparing to the dreaded FruitPhone, but that would charge whilst running wifi and tunein from 10% to 100% in about 2 hours.
I am beginning to think my SGS2 is faulty
i am fiding it takes about 3 hours to charge from empty . It does take a long time indeed but i guess it is what we have to do for a 1650mah battery
3 hours from empty with stock charger .
jje
it might well be a 1650 battery, but it starts to get unusable when it takes all day to charge then a few hours to loose it all.
This phone is the greatest but the battery life just completely destroys it, I am beginning to think I made the wrong choice

Aye... if I don't the bloomin thing would be dead by lunchtime, and I listen to music.
So I basically have to turn it off not use it so I can charge it, how crap is that, owned my iphone a year never had any problems with battery and I always used and charged in its dock.
The desire had slow charging too but snq- fixed this in his kernels maybe we can port his fix to our kernels
btw it's true li-ion batteries degrade quicky when the heat up (or completely charge or discharge)
From 30% it took me one hour and a half to fully charge..
I recommend to download battery mix as it takes very good statistic on the battery life and one can tell exactly how long it takes to charge and discharge

just for the record all Lion batteries in phones never fully discharge or recharge, as there balanced by a balancing chip.
when you get to the likes of 0% you actually have 20% charge, thats why you can power on the phone but it will immediately switch off again. like wise, charging you never reach 100%, it's more like 89%, again because of how Lion works.
if you fully discharged and fully recharged, well put it simply you'd have a lot of exploding phones, fire and chemical burns...
Interesting!
My phone charges in about 2,5 - 3 hours, so should be normal...
But charging with the usb cable connected to the pc it takes much longer.
Any of you experience the same thing?
greets!

Because:
a) That´s how Li-Ion-batteries are charged. To fully charge a Li-Ion-battery you need 3-4h.
b) The power-supply is pretty weak. It is just enough to charge the phone at decent speed, but it is not enough to charge it and intensely use it the same time. In this case much of the power is used by the phone and there is not enough left to do a proper charging. I use a 1,2A power-supply from my old Nokia, and while it won´t speed up charging itself, at least it slows down less when I´m using the phone while charging.

This is not possible. The mighty fruity-phone may tell you it is 100% charged, but certainly it isn´t
You can charge a Li-Ion-battery very fast from 0 to 70-85% you could reach this in 1h. But you have to charge the remaining 15-30% very slowly, otherwise the voltage would raise too much and destroy your battery.
The so called saturation-stage (the charging-stage until 100%) takes longer the faster you charged at the beginning. If you really charged until the saturation-stage in 1h, the saturation-stage will take 2-3h.
If you charge slower, so you reach saturation-stage after 2h, the saturation-stage will only take 1-2h anymore.
In the end it will always take 3-4h to fully charge a Li-Ion-cell, regardless how strong your power-supply is.
Another few notes:
Charging will get slower the fuller the battery already is.
Using the phone with low battery-percentage will lengthen the charging-time quite a bit, a stronger power-supply could help.
Getting the last 20% in a Li-Ion-cell will always be very slow, usage of the phone won´t influence this a lot, and a stronger power-supply can´t help.
It doesn´t matter much, how much charge is left in the battery, to fully charge it it will always take long, as you spend most of the time in the saturation-stage (the higher the left percentage is, the more time you spent in saturation-stage)

It is not faulty, it is designed this way.
It took 3 hours 10 minutes to fully charge my dog and bone yesterday whilst off

Your having a bubble bath ain't you mate
Your battery sounds faulty to me, taking over 4 hours and only charging 1 percent in an hour. Try the battery calibration app in the market, if it doesn't improve get it swapped mate

The wifi is the killer, try turning it off when charging your phone..
Sent from my GT-I9100 using XDA App
it takes so long to charge because samsung capped the charge current at 650 mA in the battery driver. but other phones like HTC allow charging at the full 1 amp. so that's why its a slow charge, and why its possible to drain the battery even while plugged in to the charger.
Now who wants to ask kernel developers to increase that to .850 or 1 amp and use that lol.
I believe lack of heatsink due to design is the culprit behind decision to cap it at .650.
Sent from my GT-I9100
3 hrs to fully charge, and as i use tunein radio a lot i can tell you on my device with the screen off, wifi on with tunein running, it still seems to take no more than 3 hours maybe 15 mins more at most
I am probably going to order a cheap eBay Li-Ion battery that's 1800mAH and likely has a charge cap closer to 1000mAH. I will know in a week when I finally get my phone and report back if that battery helps. I expect it to heat up while charging and am going to use an external charger.
Two replacement batteries and an external charger go for about $12 USD on eBay btw.
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

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?
How long is it taking you guys to charge your N7? At first I had the sleep of death and once it finally turned on after a slight charge, it stays at charging 0% for quite some time now. But before that, it always seemed to slow charge.

No idea. I plug it in when I go to bed and it's good to go the next day...lasts me the whole day. I also don't know how many licks it takes to get to the Tootsie Roll center of a Tootsie Pop.
At I/O they said the tablet takes about 3 hours to charge from 0-100% but it may be faster. Whenever I get the 15% alert I throw it on the charger for about an hour and it's past 50%
charge times will vary depending on the charger as well, best charge time will occur from the wall charger that came with it, USB trickle charge will take a month of sundays :laugh:
that is of course unless you have a magical USB controller that outputs 2A from each port (highly unlikely)
I wonder if its something wrong with my battery. Been on charger for more than three hours and nowhere near 100%. It was at maybe 48%. Drainage seems reasonable..its just the charge seems rather long to reach full charge. This is all from using the stock charger too...

Typically 3 to 4 hours for me using OEM charger
Via my HTC Rezound
Between 2-3 hours on charger, around 7-9 hours on usb.
My battery app says 3 hours and 40 minutes on average. That includes charge times when I am using it at the same time so I guess about 3 hours.
Sent from my Nexus 7 using xda app-developers app
I don't know what happened, but with me, when I first got it it was 3 hours on the dot to a full charge. Then one day it said it needed to be plugged in to charge getting below 14%. Then I plugged it in and got the sleep of death, and plugged it in the wall and the battery icon came up, then I turned it on. Now it's been charging for about 6 hours and its only 85% :crying:
Mines generally around 40% at the end of the day, it takes less than 2 hours to get to fully charged.
Mine takes about 3.5 hours but I noticed my 10 foot micro USB cable doesn't charge fast at all. Takes about 12 hours on my 10 foot cable
Yeah I'm with the rest, mine's in the 2.5 - 3.5 range. But as stated, which charger you use makes a huge difference. Charging off the computer (USB to PC) is waaaay slow. Using the OEM wall-charger is what should give you 2.5 - 3.5.
3-4 hours for me depending on what percent I wait till, usually 5-15% battery, haven't tried with anything other than the OEM charger though.
From about 10% ie when the warning to charge came up, to 100%, took mine about 2-3 hours only last night using the supplied charger. Much longer on USB, haven't timed that.
Should I get mine exchanged ? I'm still within the 14 day policy of Mac mall. Its been an hour and its only 14%. Usually it takes 3-4+ to charge fully.

Make sure you're using the supplied charger. I believe the ones for smartphones charge at a different rate? I made the same mistake when I first got my Nexus 7 by charging it with my SGSII charger. It was VERY slow. Then I switched back to the supplied charger and everything was normal.
Usually takes me just 2 hours, and it is full. I usually start charging at around 15%. Using OEM Charger too. :good:
I used my Gnote charger but left it overnight (about 5hrs). I'd say that normally it takes around 3 hours. The battery life is awesome I have to say.

I found this while searching for an answer, my Nexus has been taking 12-15 hours to charge fully, using the factory charger. I also tried my powered USB hub (using a charging port, rated at 1.5 amp), and my Galaxy Nexus charger, same thing. Called Google today and they said it's the device, and I need to return it. Luckily I bought it locally, so I can just exchange it at the store.
Hello Experts,
I received a new nexus 4 and noticed that it takes around 3.5 to 4 hrs for complete charging from 5% to 100%.... is it normal? my other sony xperia seems to be charge in about 1..5 hr
since i am new to Nexus 4, not sure what is the avg charge time and should i call for RMA? Please let me know what is the avg time for charging.
thx

Perfectly normal. You want a nice slow steady charge, especially in a sealed phone. The battery needs to last as long as possible. Fast charging batteries significantly reduces their lifespan. My old Nexus S takes the same amount of time to charge from 5%.. 3-4hrs or so give or take.. I still have the two year old original battery and it holds a charge just as well as it did the day I bought it. Meanwhile my 15 minute charge AA batteries I bought last year lose their charge in a week just sitting on the desk.
Mine is just about the same, but that's under use. If I don't touch the phone, it typically charges to 100% in about an hour.
And if it's through USB.. um.. more like 8 hours to fully charge.
Battery widget reborn (awesome app btw) says my phone usually charges in about 2.5 hours. This is on Qi though not sure about the regular wall charger.
2-2.5 hours for me on usb wall charger and Qi Orb.

yes, this is one of the reasons i started this thread to understand what everyone is experiencing.... i called up the google customer support and they are ready to send in a RMA as it appears to be a higher side...
so let me know your thoughts guys...should 3.5 hrs charge time considered high and warrant a RMA? share your thoughts.
^ Hmmm.. I doubt if this would mean anything serious or worth RMA-ing. I can but I won't RMA my device because it's been exceptional so far. I am fairly happy with it and wouldn't want to get it replaced with a defected one.
Its perfectly normal especially from around 5% to 100%.. In my experience if you dont let it get below 20% it usually charges faster. I wouldnt RMA it especially if your phone is perfectly fine in other aspects.
I tried with a different charger yesterday and it took similar time. The charger has same voltage input levels.
You charge 3 hours, for only double the lifetime. How pathetic, actually. I didn't thought that the battery life would be that bad. I can hardly make trough 1 day, if I play some games, make some calls, and use a little bit of internet. On the last charge I got 4Hours of screen on time with 15% left.
Gosh, at least it's fun to use it. :/
