Samsung Galaxy S :: Prolonged Battery Charging

Jun 10, 2010

Prior to getting the Galaxy S, after I read what Samsung were saying in the manual of not to overcharge, I investigated the reasons and wrote in various topics on the battery and the differences between Li-Ion & Li-Pol battery types.At that point with all the evidence found it made sense to believe that what Samsung were saying in not to overcharge was accurate.Basically, at that time it was believed the phone used a Li-Pol, Li-Pol batteries are different in that they are 'wet cell' as opposed to Li-Ion which are 'dry cell' charged.Li-Pol can be manufactured much thinner but can not be manufactured in different shapes.This is to allow the wet cells whilst under charge which become hot to move around the battery freely. If a Li-Pol was manufactured in different shapes like Li-Ion it would create a 'hot-spot' in an area where the wet cell could not move fluidly around the remainder of the battery.However, it has now come to light that this is not the case and that the batteries provided with the phone are indeed Li-Ion.Anyway, moving on to the present.

After now getting the phone and doing a bit of testing I have found the overcharging issue NOT to be an issue.When you commence a charge on the phone the icon changes to a charge state.However, once the battery has reached maximum charge capacity the battery icon automatically changes to a 'Non-Charge' state and then the phone simply runs off it's own battery. This is despite the phone is still connected to the charger. It's just that the charger although still attached is no longer charging the battery.As soon as the battery falls below a certain figure (I've had different figures ranging from 98% right down to 91% which is probably due to whatever the phone is doing at that particular time to wake the phone up from realizing "hey, you are still attached to a charger, now wake up and start charging again").

Samsung Galaxy S :: Prolonged Battery Charging


General :: Galaxy Nexus - Battery Not Fully Charging

Sep 9, 2012

My specific device is a GSM Galaxy Nexus.

So, I have 3 batteries for my phone. 1 stock (1750mAh) and 2 extended (2000mAh). No I don't need all that juice... its a story for another time. Anyway....

Lately when I charge a battery in the external charger (using a USB cable and the wall plug supplied with the phone) the battery will not fully charge. The LED on the charger will change from red to green (Usually I charge the battery overnight, or while I'm away at work during the day). However when I put the battery in the phone, it will show somewhere between 80%-90% charged.

1) Would a 100% drain and charge reset the battery's "fuel gauge"?
2) My phone automatically powers off at 6% (which is fine, needs enough juice to save current settings and power down properly). Is there a way to truely drain the battery down to 0%? (I'm thinking of some kind of low-voltage lightbulb or LED connected to the positive and negative terminals should drain that down to 0%. Is this recommeneded or is it fine just running it down till the phone powers off?

Normally I try to plug my phone in and charge (or power off and swap batteries) once they hit about 40%-60%. I'm only interested in doing a full drain to see if that will get these batteries to fully charge in the desktop charger. Besides I've read from a few sources that it is GOOD for the battery to do this once in a while (Fully drain, charge to100%) to properly maintain them.

And as a side note, charging the battery in the phone (either with the wall plug or from USB cable on my computer) will always result in a 100% charge, which makes me thing the issue is with the desktop unit itself (perhaps faulty circuit that cuts off charge current when it thinks its full ?)

General :: Blue Triangle In Battery Screen - Galaxy Y Not Charging

Jan 1, 2012

My sister has a Samsung Galaxy y phone running Gingerbread 2.3.3 (not rooted). She plugged the phone after it ran out of charge and saw this screen (pic attached) with the battery icon empty and a blue triangle with a crossed out battery symbol inside it. The phone would not power up.

We tried everything : checked charger, plug points, usb charging, taking out battery and cleaning contacts but everything is fine.

Samsung Captivate :: Is Battery Defective / Not Charging?

Nov 13, 2010

I've had the captivate for about a week now and I haven't noticed much improvement on the battery life. I have discharged/recharged the battery a few times and nothing much has changed. The main issue is that overnight, the phone will go from 100% charge to 75/80% charge. I only have wifi on; bluetooth, gps, sync are all off. I also kill all applications except for a battery status notifier and the sms application.I have noticed, though, that when I sometimes open the task manager I find applications that are open, which I have never touched (ex. music player, video player). Could this be the problem and how would I fix this.Any help is appreciated cause at this point I have trouble making it through one whole day with the phone.

Samsung Captivate :: Battery Not Charging Long Enough

Aug 5, 2010

To all those who have battery issues.... How long do you charge your battery for? Check this out:

Saturday night -> Sunday - charged phone for 7 hours
Sunday - about 18-19 hrs of battery life - moderate usage
Charged from 6pm sunday night to 4am monday - (10 hours on charger)
Monday -> Tuesday - 38 hours of battery life - moderate usage
Charged tuesday from 1030pm to 4am wednesday (6 hours on charger
Tuesday - 16 hours of battery life - moderate usage.

BOTTOM LINE: I think the phone says it is charged way before it actually is full. Let me know if anyone else is having the same issues....

Samsung Captivate :: Battery Charging Habits

Sep 22, 2010

So coming from a BB and iPhone I never had to worry about leaving my phone on the charger all night. This being said I would like to do the same with my cappy but I am afraid that I will destroy the battery. Do you guys leave your phone on the charger over night? The only reason I am concerned about this is because the stupid phone actually tells me to unplug it when it is charged. This leads me to believe that it will over charge the battery if I leave it on...

Samsung Captivate :: Charging Battery On And Off Cause Any Damage?

Jul 22, 2010

Ever since I got my Captivate, I've been charging the battery on and off, here and there, never completely, an hour or so at a time, whenever I noticed it running out. Then I read the manual, and it says there that the battery should be "completely" charged for 4 hours before first use.

Have I caused any damage to the battery? I thought with modern batteries we don't have such restrictions and problems as we did with the old batteries (battery memory, discharging once a month, etc).

Samsung Vibrant :: Charging Battery From PC - Is Different Plugging USB Cable?

Sep 26, 2010

With the Samsung Vibrant there is the USB cable and the charger that you plug the USB cable into (to charge it from the wall). I was wondering if charging the battery from a PC was any different the plugging the USB cable into the wall charger? I would like to just keep the USB cable plugged into my PC and charge it that way but I want to know if it will get the same charge as it would with the wall outlet.

Samsung EPIC 4G :: Poor Battery Charging Time

Sep 23, 2010

I am coming to the conclusion that the poor battery charge time is a result of the batteries and not the phone. The reason I believe this to be true is: I purchased the charger that comes with a spare battery and it takes a good 3-4 hours to charge in that, with no phone attached. Batteries in my previous phones would take an hour to fully charge in a dedicated charger. I bet when Seidio comes out with batteries for this phone, we will see much better charge times and possibly better battery life.

Samsung Moment :: Battery Requires Frequent Charging?

Nov 21, 2010

Been complaining about my moment something terrible. Went Friday spent the money and renewed my contract to get the EVO. The guy warned me about the battery on the Evo being bad. I didn't listen since my friend in work plays with his for 3 hours before getting a low battery. Got the Evo and charged it friday from 11am till 4pm. Light turned green full battery. Didn't mess with it much cause I got busy. Had 3 calls about 5 minutes each. Got on the internet for 10 minutes. Phone had gone down 1 bar at 8pm and didn't use it after that. Went to work at midnight to work overtime to pay for the phone, pulled it out at 2am "RECHARGE BATTERY". Ok, charged the battery from 2am till 5:30am. "full charge". Played with the phone about 10 minutes setting it up, made a 10 minute call, 8am when I got home played with it for 5 minutes. Took a nap, woke up at 1pm, RECHARGE BATTERY. Ok, charged it from 1am till 6pm. Green light, battery charged. Made 3 calls, looked on facebook for 10 minutes, sent 5 text messages, went down 1 bar. From 8pm till 3am I slept. Woke up at 3am, grabbed the phone, it was turned off. Turned it back on, powered up, "RECHARGE BATTERY", phone shut back off. THIS IS RIDICULOUS WITH THESE PHONE BATTERY.......

Samsung Moment :: Charging Port - Battery & Malfunctioning - Drains

May 14, 2010

Problem is that both charging port and battery and malfunctioning. My charger port has a mind of its own. Only certain chargers positioned in certain ways will charge it. I'm talking about brand new charge cords (no shorts in cord itself) that when plugged in will over work if I play with the port for awhile. Along with the problems actually getting the charging port to work, there is also problems with the battery. The battery has a terrible life using all of the battery conserving settings it drains like crazy. And along with that when I charge my phone with it off it will tell me fully charged many times but when I turn the device on I'm in the RED.

Samsung Vibrant :: Stop Vibration When Battery Is Finished Charging

Jul 22, 2010

I keep my phone near my head on my bed, since I use it as an alarm clock. Unfortunately the Vibrant is vibrating at the end of the charge cycle, which is distracting when I'm trying to fall asleep!

I can't find a setting to turn this off. I have haptic feedback turned off. I keep the phone in vibrate mode (ringer volume = vibrate).

Samsung Behold 2 :: When I Plugged In / Battery Charging Logo Didnt Show Up

Dec 13, 2009

Just for starters I have not rooted my phone or done anything of that nature. I've only had the phone for about two weeks. I've had an issue with it rebooting on me, though it was due to Locale since the first time it rebooted on me, that was the only thing I had done to the phone. The developer said there was an issue with the api's from samsung.Well since then I havent used Locale, removed it, yet its rebooted just a couple of times(compared to 3 times in an hour when I had locale). Now today, I found my phone completely unresponsive. Black screen, no lights, dead. I pulled the battery, reinserted and tried to power on. It charged overnight so it cant be a dead battery.

When I plugged in, the battery charging logo didnt show up, so I did a reset(vol down+ call+ power), got the behold ii boot logo with Recover text, so I hit the home button. I then got a logo I've never seen. It was a logo of the phone with the warning exclamation point inside a triangle. I left the phone alone for a while but it was still there. I pulled the battery again, reinserted and powered on to a normal boot and the phone came on.I'm going to talk to Tmobile about replacement as this is really weird and I havent seen anyone else say thing like this. And just for info, my battery does have the same serial number that others have found to have an issue with. I'll update with any other info I find out, but I'll probably just get a straight swap without any feedback.

Sep 9, 2013

So, I have the Samsung Galaxy Chat (GT-s5330) and I have a weird problem. When I connect it to a charger (happens on wall charger and on PC connection) it turns off immediately, and it can't be turn on whatsoever.

Samsung I7500 :: Battery Screwed - New Battery For Galaxy?

Sep 13, 2010

I connected a usb cord that came with my galaxy, to the front usb ports of my new computer. I built it myself but i think i connected the from case usb cords wrong to the mobo or may be the mobo is defective. My phone turns off as soon as i connect it to the usb cord connected to the front. Could the battery be screwed? My phone still boots up, it just doesnt charge as fast. If not at all i left it connected to the wall charger all night tonight and it was only half charged by morning. Should I just order a new battery off ebay for my galaxy?

Samsung Galaxy S :: Phone Battery Gets Hot / Why Is So - Fix It?

Oct 16, 2010

I just got a new Samsung Galaxy S phone from a local AT&T store in the US. I took the phone home the first day and spent a few hours scrolling thru the menus and getting familiar with the phone. I did a software update on the phone it has ver 2.1. I also went to a few websites to test the browser. I made about 3 calls and talked for about an hour. I had the phone turned on the entire time, I was not in standby mode.
After about 2 hours - the back of the phone where the battery is, started getting hot.

It didn't burn my hand but it was like holding a very hot cup of coffee in your hand. Very uncomfortable. Has anyone else had this problem with a battery getting hot?

Why is the battery overheating? I'm afraid to use the phone now, it might burn up something in the phone or ruin a memory card or something else.
What's causing the battery top get really hot? How do you fix this problem?

So how do I make my SGS not use 90% of my battery life?

PS. Got the brightness at 0 and the sound volume at 0 (Only on vibration atm)

Samsung Galaxy S :: Battery Life Vs Usage

Aug 8, 2010

However, this simply has not been my experience at all, I get a couple of days out of my SGS whereas some others report only getting a day.

I just thought it would be interesting for us to post in here how much battery life we are getting for the amount of use we put the phone to.

There must be some sort of pattern.

My usage:

anywhere between 10 - 30 texts per day.
Several emails - sending and recieving.
a few phonecalls.
30 Minutes of gaming.
Twitter.
Live wallpaper running.
BBC News widget running and Weatherbug widget running.
I also listen to some music but this varies day by day.
3G and HSPDA are left on constantly as is my wireless.
GPS is turned off.

Thats my usage and i get at least a day and a half. Would be interesting to compare...
