I'm wondering it would be okay to remove the Ace's battery and run it on the AC power adapter that charges the battery.
I have read about battery issues here since I got my Ace a few weeks ago. I'm a little disappointed that the charging circuitry isn't smart enough to stop current fed to the battery when the phone signals that it's fully charged. Because of that it's recommended NOT to do what most people probably do... leave their phones connected to the AC charger overnight.
But I haven't been able to find anything on whether or not it would be harmful to pull the battery so it won't overcharge, and run the phone directly from the AC adapter. I didn't realize the phone had such a great radio receiver. I'd love do for long periods of time what I've been doing briefly from time to time on battery... plug it into the audio input for my stereo and play the radio, MP3s, audio from YouTube videos etc.... but powered by household AC.
Anyone know if there'd be any issues doing that?
I tried it , doesn't work unfortunately .
Ace-ing all tests.
Well it was a thought.... Thanks.
My old nokia dumbphone can do that
Btw the phone is smart enough to not overcharge even if u leave it plugged overnight. Its called trickle charge or something, when battery is 100% full it'll stop charging, and when it discharge to 99% it'll charge again till 100% and the cycle continues. Moreover when phone shows 100% charged it was lying all along, to prevent sudden overvoltage. Maybe its just 95% when it showed 100% full

Do you have any links to pages that detail testing that? I googled for quite a while and only came up with a couple hits that said suggested the opposite. But it seems Samsung and the Android OS would be smarter than that.

That sure sounds right. I downloaded an app that displays battery charge by percentage increments. After charging the Ace until it gave an audible notification, within seconds the battery indicator dropped from 100% to I think 87% and stayed there for quite a while.
Well I found a stress test on the Galaxy Ace that says, "The battery contains a microchip that protects it from short circuits and overcharging."
But again I came up with this information saying, "... never put your phone for charging over night as this may hamper the battery’s life very badly..."
There must be definitive info out there on the phone's charging circuity. But I haven't found it yet.

unplugged my phone at 8 read xda forum for 5 mins got to work right now 943 already at 89 percent. Does this seem normal? I been checking better battery stats but don't really understand it. I feel like something is trying to sync. i have fetch off for email and Facebook. anyway to diagnose this on saurom rc4 clean boot.

Are you overclocked? If you are, which governor are you using? I've posted in the OC kernel thread about an issue where the CPU is running at max frequency the entire time causing a huge battery drain.
I am right now but its showing me deep sleep and 192mhz on demond has a big percentage. Its not running max clocked i know that.

This is my shots I'm at 78 percent now been on xda for maybe teen more mins. My brightness is one step above min level. Its like 1 percent every 3 mins when screen is on even if I'm idle.

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

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.
As the title would suggest, my poor GS2 gets VERY hot when charging. Not all the time, but often.
If I charge from my PC's USB, it doesn't, but when I use a mains charger, it overheats.
When I finish my night shifts, my battery could be down to 20%, so when I go to bed, I plug in the phone, set it's alarm and pop it under my pillow, like I have done with every phone I've ever owned without issue. I wake up during the night and pull out the phone to check the time and almost leap out of bed because of how hot the device has become.
To make matters worse, it's discharged in battery power. This morning was the final straw, as when I checked the phone and it was red hot, it was also dead. I held down the power button and booted up the phone. It showed 15% battery left. I know people say that when it's charged, remove it from the charger, but it isn't practical. Besides, I've never had to do this on any other phone I've owned. This is unacceptable for me to rely on any more. Is this a common issue?
Or my fault because I have rooted the phone the tried custom roms/kernels/modems on it before?

1) change to a diff kernel and see for the issue.
2) well charging from 10~20% to full 100% will lead to heat up the phone than charging from 50~60% to full 100% , hence also check for the same and see

I should have mentioned. This happens on any Rom and I've tried 4 kernels and still the same issue. Only thing I haven't tried, is going back to Samsung stock rom. Going to try that today, see if that solves it and report back.
Like Samsung told my wife "when it gets hot dial *#*#4636#*#* and note the battery temp".
Is it still under warranty

Well the PC's USB output would be limited to .5 A whereas your wall charger could provide 2 A. This might just be normal IMO, although I can't say that my phone gets ridiculously hot during charging. As others mentioned, I would check the battery temp.
The issue is already in his post and the solution as well.
1) The S2 has the tendacy to get hot. Its all very compact and there are no internal ventilators so the S2 dissipates heat to the rest of its body.
2) There is a Power difference between the charger and a USB cable. The charger gets hotter since it delivers power directly of a higher voltage and slightly higher amps then a usb port.
Your issue comes from one sole thing. Your bed. beds have very poor heat dissipating abilities, in fact, it has none. Considering no fresh air is delivered to your device, because it is stored under your pillow. Not to mention your pillow, the rest of your bed stop heat from leaving and it builds up. Ontop of that your heavy head is resting on it, pressing the pillow tight around the device.
in short, it has no way to relieve the heat. There is a simple solution of a non technical matter. Don't put the darn device under your pillow.
(the same counts to people that use there laptops on there beds pillow or covers without a proper cooling matt, before wondering why the hell there device shut down all of a sudden.)
The problem is you put your phone under your pillow. I made this mistake a few weeks ago and the phone was too hot but no problem when i charge it somewhere not under the pillow
I agree, I should stop doign that. But one question, if that's the case and the getting hot is normal, then why did the battery drop from 100% to 8% while plugged in?
Your cooking the battery, thats why.
i'll admit i charge my phone and leave it ON the bed so air still circulates but it did used to get hot. Not sure if any changes i've made such to things kernel, ROM, modem or undervolting has caused my change in temps but my phone never feels warm anytime day or night weather its on charge or not where as my partners phone (stock sgs2) does get hot using the same charging habits as myself

Another odd issue. If I mains charge my phone or connect it to my laptop(not PC the PC charging seems to not effect it) the phone lags. Menus take longer and it really struggles to register my touches on screen.

For the AC charger this problem is known: if the charger is of poor quality it will generate too much 'noise' (ripple) which disturbs the electric field used by the touchscreen. However the original Samsung charger is of good quality and does not have this problem.
Experiencing these kind of problems when charging by a laptop USB port however is abnormal.
Interesting.
I bought an official Samsung charger off ebay, and it produces the same results. Much to my frustration.
Leaving it plugged in all night however was fine, I placed it on a shelf and the phone was actually cold when I woke up. I'm just worried the battery is ruined. It seems to drain quite quick.

Another problem i faced recently was the battery draining to fast, i was told to pull the battery out for atleast 3 mins, this lets the CPU etc cool off, since then i've had no problems at all and getting a good 12 hrs atleast on battery use

does anyone know if its possible to find out if the s3 is really charging or not? ive been plugged in and it's still discharging. I need to know if its hardware or software related. when plugged in it has a lightning on the battery and it has red led when display is off but its really slow on charging

The battery does not charge to 100 %, this is not a defect in the phone but rather a sort of internal protection so as to not damage the battery. Indeed, it happens many times to leave the phone connected to the charger much more time necezzario.
The battery by doing so you may receive a surplus of energy than necessary, and in the long run, deteriorate more quickly. Samsung has inserted inside the Galaxy S3 a limiter that operates in the following way: while the phone is charging, you download slightly of 2-3% for then recharge automatically up to 100 %. This process is repeated automatically from your phone until it is removed from the charger.

While plugged in go to settings/battery and see if it is ac charging or usb charging....I've had this problem with the new cable and plug, it only charges at usb rate, use my old S1 charger now, BlackBerry one worked for me as well

Hmm, im not talking about when it charges at 100 % im talking about when it charges in mid ranges like 50 or 80. It shows charging but an hour passed but it didnt even increase to 2 percent
Are you on an original rom or a custom / leaked one?
Have you tried another charger or computer?
It may take some time to charge on slower chargers (the ones only outputting 0.5Amp) but it definitively should not be discharging when connected to a charger with the screen off.
Im on stock firmware. Using the wall outlet ti charge the phone
Hello!
I am facing,lets say a issue, when charging my L920 on charger and phone is OFF. I put on charger after 2-3 minutes it starts by it self....
Does it to anyone else also? It is normal? I just want it to remain switched off while charging like this, but its not a big deal ofc.
Thanks
It is the normal behaviour of ur phone, so be cool with it. It is not an isssue.

But isnt it better for phone to charge up while its off? i mean it deffinately has less power consumtion in off state :] so it can charge better ..i guess
Seeing as the phone has a 2 Ah Battery and the charger is 1A, you can recharge your phone in about 2 hours (That's from 0 to 100 with a 100% efficiency, usualy efficiency is lower but you usualy don't let the phone drain to 0 ). The power it drains during that time will probably not affect the charging time to much, you can probably charge it in 2h 15m if it's turned on. In short: The time you would save by charging the device turned off is insignificant.

This question came up a lot when the WP7 came out (it's not a Nokia-specific issue at all).
The gist of the reasoning is that the phone's charging isn't a "dumb charger" that dumps a bunch of current into the battery and hopes it charges eventually (ideally without exploding). Instead, the phone has an actual charging circuit that tests the battery capacity & incoming current to determine how charged the battery is, and cuts off the current when it's at 100%.
This is actual "software" that runs on the phone's processor, and thus requires that the phone be on for it to work.
You'll get used to it.

Thats one serious answer, something i hoped for. Thx a lot for explanation.
First I don't think anything is wrong with my device but just curious if anyone else noticed this.
1. Fully Powered off device
2. Plug in charger (little battery charging icon animates)
3. This is where it gets strange I let it get to 100% but didn't unplug it (left it plugged in all night like I usually do on all my devices) , next morning I check the charge and it showed 97%
so I assume the phone circuitry shuts off the charger after it's fully charged to prevent overheating or whatever, or the charger shuts off, strange why I got a 3% drain though with it completely off...
so far I have only tried with the official charger and cable, curious if anyone else had this issue.
besides for that the battery in this device seems good I can get about 1 day 1/2 moderate / heavy use out of it
Perhaps it's the boot animation etc?

I guess it could be if it runs in the background , it just was strange to me since my samsung tablet will always show 100% even if I leave it plugged in forever, maybe lithium-ion (samsung) and lithium-poly (xiaomi) have different charging rules like maybe you can't float charge lithium poly (just guessing)
