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

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
Sent from my SAMSUNG-SGH-I897 using XDA App
DigitalEagle is correct...Li-on batteries are very picky about overcharging
i made this post because people might be wondering about how to charge their phones.
(i say these things from experience so if different for anyone then let me know)
make it a habit not to charger until its at least 15% or less. i always charged my g1 and left it plugged in even at 100 and after weeks the battery life went to hell. i went through 3 batteries that way.
Also try not to use the phone while its charging. i cant really explain what the hell causes that but i know from experience of two other phones that the phone overheats and messes up the battery. so that means avoid over-night charging. i charge mine either before i go to sleep of first thing when i wake up.
also when ur charging ur phone, DO NOT put it under anything, like between a pillow the bed. ur phone will overheat like to the point of too hot to touch. also from experience.
Thanks man,that why my old battery started die'n so fast

I normally do this to calibrate battery:
1. Charge to 100 % with phone on
2. Unplug and turn off
3. Charge to 100% when off (i normally leave it for 10-15 minutes)
4. Then unplug, turn it on, then after fully booted turn it back off
5. put it back on charger till it fully charges again
6. boot into recovery and wipe battery stats
now use your phone as normally and give it 3-4 full charge cycles till the battery is properly calibrated.
Battery calibration is a app on the market. Check it out! It saves you from having to go into recovery and wiping battery stats

i follow all of this and i usually get around 20 hours of battery life. and ive only calibrated my battery once.

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

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.

Hello !
I have read several articles in where people use different methods to charge theyr battery.Maybe it has been talken in XDA too but i havent found nothing that regards charging
How do u charge the battery ?U keep the level from 90 % to 50 % and once a month u fully discharge and than fully charge ?
Or u fully charge it after it shuts off cause of low battery?
Thanks
I'm a bit of a battery abuser, I tend to charge randomly when I think it will be under heavy load such as long drive in the car listening to music I will plug it in with my cigarette usb adapter thingy..
Most other times just plug it into my laptop. My habit for discharging and turning it on until it dont turn back on is maybe every couple weeks to a month if I remember to. Bout that time is when I start cycling out old apps I don't use and just maintaining clean phone status.
...Wall charger every night, all night, while still on, while I sleep. Been doing it this way for 2 years and still using the original battery.

Lithium Ion batteries don't have memory effect, so the only reason to run a complete drain and recharge is if the battery fuel gage needs calibration.
I leave mine on the AC or USB charger everynight. The Captivate's power management chip reduces the charging current when the battery approaches full. After becoming fully charged, it stops charging for an hour or two, waiting until the voltage has dropped about 0.1 V, then resumes the small trickle charge until full again.
You want to avoid getting the battery too hot, because that will reduce battery life (life= number of battery charge cycles). I have an alarm set in battery monitor widget (bmw) when the battery temp is 45 degrees C or higher. you can get bmw or other battery tools on Google Play.

It is my second time that i fully drain and fully charge my battery.
It is wrong what im doing ?
I don't think of it as right or wrong. You don't need to drain it all the way or charge it to 100% if it is not convenient.
I put my phone on the charger at night even if the battery is 60% or more full, with the phone on. I want it at 100% in the morning. During the day, it often gets charged while I am driving or when I am using my laptop. Is is seldom fully charged during the day, and it rarely gets drained all the way.

I have four batteries for my Captivate, because the original seemed sorta crappy, and I found supposed-OEM batteries pretty cheap on Amazon.
My micro-USB port seems to have taken a crap, and the phone will no longer charge via that method. So basically, I have an extra-battery wall charger going all the time, and I swap batteries whenever the battery in the phone dies.
I just connect the usb cable port from my Xbox to the phone when I'm at the man-cave table. At night to my computer's usb port since it still power's up when the computer's off which is convenient :laugh:
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.

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.
