Ok so I charged my phone up. When it said it was fully charged I took it off charger. It went to 98%. I then plugged it back in and waited till it said charged again. I repeated this for about 30-45 minutes and when I took it off it stayed on 100%. Its been maybe 30 minutes and its down to 99%. Weird eh?

thats whats called bump charging.
if you read the recalibration thread you'll see that what you did is similar to what you're supposed to do to recalibrate your battery.
This is how lithium ion batteries work. Keeping them at 100% actually shortens their life span. The android system tries to prevent it from charging to max for this reason. Unplugging and replugging in like you did tricks the battery into over charging. It won't causing damage once or twice, but try to not make a practice of it.
Wow,thanks for that. I was gonna do it everytime so thanks for the heads up

Yeah, bump charge a coupla times then clear battery stats from cwm. it will turn into the new 100%
Great advice guys, I had the same question, now I know, thanks

DigitalEagle is correct...Li-on batteries are very picky about overcharging

Hey forums, very simple question is charging the phone overnight bad for the infuse? I always get a warning to plug out the phone in the morning. Can overcharging be bad for my battery? Merci.

Do you mean that you get a warning after leaving it plugged in all night?
If so, check to make sure that your cable is connected properly. On some cables, the connectors are not fully touching.
What I was trying to say is. Usually the battery is able to charge fully overnight. But then it probably just sits there with the charger in until morning when I pull it out. I was wondering if the extra time its charging on full battery is bad.
Sent from my SAMSUNG-SGH-I997R
Nope, its not bad, whenever the phone reaches 100% it disconnects the charger till it drops to 95%,then it starts charging again and so on,at least that's the case with my phone on official and custom roms

I put it on charge when I go to bed, and unplug it when I wake up. Just make sure to keep it in open where the phone isn't covered.
Thanks for the responses! I wont worry about this anymore.

Make sure to always use quality, reputable chargers and not the ones you buy at the flea market that say "Made in the Democratic Republic of the Congo".
Lol no problem. I still have the charger that came with it

Yes it is bad, because it will overcharge your battery. It takes a while, but if you overcharge your battery constantly then the battery life slowly starts decreasing until it dies.

In a sense this is correct as the same as playing on your phone while its charging I wonder if we have a unplug app when I was on the evo we had a app that would disconnected the charger when full and wouldn't read it until the battery was at 80%

The phone doesn't actually charge the battery to 100% unless you're using an SBC kernel. You can leave it on the charger as long as you want and it will never overcharge unless you have some kind of malfunction.
Been only charging overnight since I got the phone last May.

So, got this weird glitch. I'll have say 30% of my battery left and I'll power cycle and suddenly I'll have something like 4% left. And power cycling doesn't help or anything. And plugging it in just charges it from that 4%. Anybody got anything?

Just thought about this. I should probably let you know I'm on the latest official stock.

Im runnings the official Roger's GB ROM on my Infuse ATM and I've had similar issues. Mine goes a bit deeper though.
When I first got the phone, it wouldn't charge to 100%, whether it be on or off. When the phone finally charged to 100%, the second you unplug it, the battery widget I had and the built in battery meter on the phone said it was at 80%.
While using the battery, it would drain, sometimes suddenly dropping from 40% to 10%. The only way to get the phone to charge to 100% while its off is to charge it for about 8 hours or overnight. Even then, upon bootup, the phone read anywhere between 80%-85%
This is the OEM battery. Im going to try my luck with a battery off eBay that claims to be "OEM", but so far charging for 7 hours straight with the phone off, it wasn't able to reach 100%.
So im hoping it's not the phone itself. Ive charged the phone with various charges, usb cords, and used juice plotter to keep track of things. Definitely something fishy going on because my graphs always show a sudden jump from 85% to 100% in a span of less than a minute =\

I don't think it's b/c of the rom your on, happened to me when my phone was stock. I tried to let it die, but once it hit zero percent, it just kept going till the "true" battery percent was drained. Im on S7 now and it still happens occasionally..
I had the infuse on the AC charger the other day, when I took it off, it had a message stating charging stopped because of battery temperature. Now battery will only charge to 35% no matter how long its plugged in. Also when phone is off the charger, phone is getting very warm to the touch and the phone is not being used. Do you think I need a new battery or is the charging circuit messed up? Thanks for any input!!!
Sent from my SAMSUNG-SGH-I997 using XDA App
If your able to plug it in and it shows it's charging then there is noting wrong with the circuitry. Your gonna need to replace the battery.
A new battery is much cheaper than a new phone.
Batteries heat up as the internal resistance increases over time. As Axiomkid suggests, get another battery. Do it soon. Old (or defective batteries) overheating run the risk of shorting, leaking, or exploding.
Better yet get two batteries and maintain them properly ie discharge to 10%, recharge to 100%, then swap out with another battery and let the recharged battery cool down.
Tried a new battery, it charged to 100%... but drained 50% in one hour. When I charged it again same problem is still happening. Thanks for all that helped.

You might need a new charger too. are you using the original Samsung charger? Try charging it from a PC too. The 50% drop in the charge could be a calibration issue too. It would improve that reading over the first few charges with the new battery.
yes i am using original charger, i have use a captivate phone charger as well. i think they are both the same. i'm thinking something is wrong with the phone because after charging and taking the phone off, the phone is getting really hot without being on the charger. like the phone is being used but it's not. could maybe the rom cause an issue like this? i'm thinking maybe trying to flash the phone with a stock rom and see how much the battery drains
Problem solved!!! Reflashed ROM and all is good

I heard that leaving the phone plugged in for a long time can affect the battery's performance. Is it bad for me to leave my phone plugged in for 24 hrs+?

keeping an li-ion battery fully charged all the time is not so good for it, not because it can become "overcharged" but because your not using the battery it may suffer from capacity loss, the ideal environment for the battery would be to let it discharge to about 50-20% then charge it again till full at least once in a while so that it is maintaining its cycles and capacity. :good:
OK thanks.

I always charge mine for a couple hours before I go to bed that way I don't leave it overcharging. Throw it in airplane mode and go to bed that way ur battery doesn't drain too much overnight.

Also is it bad for the battery if you reboot a lot?
Pretty sure the phone's charge circuit isn't going to do anything to damage the battery. Once it's charged, it may go to a tiny maintenance trickle charge, but you will be fine. Rebooting also will just drain your battery, not damage it, as it uses a lot of CPU and I/O to get Android fully up and running.

Not bad for the battery but I guess you'll have to charge it again sooner
Nice thread on Li-Ion batteries http://forum.xda-developers.com/showthread.php?t=669497
So on a daily basis I should run the battery down to about 20-40%, and then charge to 90-95%?

it cuts off when its fully charged so i wouldnt worry, also you dont have to cycle charge li ion battery's even if you only run it down to 60% and charge it, it wont do it any harm, infact they like to be charged willy nilly as its keeps the ions jumping about or something, haha
My phone's battery goes down if it's charging and the data is on until the phone dies. I'm using miktouch and Hyperion's extended battery. It also doesn't seem to charge fast at all (12+ hours). Once it's "dead"it will power off, then randomly go back to 100% battery (orange light to green light).
Anyone else have this issue?

First guess is you have a defective battery. Draining while connected to the charger should never happen with a good battery.
I guessed as much too. These Hyperion batteries go bad quickly. I've had five since January.

I just got mine. It says to not use more than 4.2V to charge it. My chargers are all 5.0V. What kind of danger am I playing with buy not buying a compatible charger?

With LiPo batteries there is the danger of explosion/fire. I have an Anker universal charger and note that the output when plugged in is 4.2V. However, USB ports output 5V, so I would think the Anker battery can tolerate that otherwise you would not be able to charge the phone by plugging into a USB port.

I hope so too.
So, brand new anker and the battery still decharges when plugged in and goes full charge once the phone is off. I'm thinking there's something broken with the phone and not so much the batteries.

From a lot of the comments in this forum, I suspect the phone has a charging circuit controlled by software rather than hardware. Before you do anything hardware drastic, you might try flashing a different kernel.
Also, you report that the battery leaps to 'full' when you disconnect the charger. Have you tried measuring the battery voltage physically with a multimeter to see if the battery is charging at all. Should be 4.2V when fully charged. Something like 3.6V when empty. Obviously if you put the battery in for half an hour and the voltage goes up, it's charging no matter what the UI says!
I've not tried either of those. I don't completely understand what the kernel is. I'm using Miktouch rom, but I don't know how much that has to do with the kernel. I know the battery is being charged because if I leave it plugged in for a good 8 hours it holds its charge for the day. And if I leave it plugged in for say, half a day, and turn off data/wifi, it will slowly show increased charge, like a percentage per half hours of charging.
What do I need to know and do to flash a new kernel on here?

Your the only one of my users to ever have this issue, including me. And the doubleshot was my last device before going Nexus last February.
What I would do is:
1. Backup all your user downloaded apps with Titanium Backup.
2. *Do a full wipe from recovery*
*Wipe data/factory reset
*Format system
*Format Data
*Format cache
3. Flash MikTouch and reboot.
4. Once rebooted don't go cramming apps and settings back into your phone just yet. Make sure its going to charge and drain like its supposed to. If all is well, then start 1 by 1 with your apps, making sure each of them are not causing your issues. If all tests are passed then something in the ROM its self went stupid.
Sounds like hardware though.
