I was just curious about what your methods are when it comes to charging your DINC. Feel free to reply with any comments, and information, (i.e. if you're using a battery other than stock, etc.)

Stock battery, no bump charging, less than stellar battery but I'm thinking Google music beta is the culprit.
Plugged in overnight and sometimes plugged into Car Charger.....And thank you for the charging hack, or whatever its called, that you included in your awesome Kernel Chad, because car charging wouldn't do anything before.
Plug in overnight to charge. unplug when I take my dog out fr his morning business. Plug into car charger on 20 minute drive to work. Unplug when the green light comes on. Gets me 6:30 am to anywhere between 6 and 8 at night with 50% + left when I leave work.
I keep it plugged in pretty much anytime I'm home, and always overnight...that may be too much, but I use Wireless Tether often at home, which really drains the battery. I do have a 1900mah battery from HTC Express, though. I've heard of some who have 2+ batteries that they switch out every day, but I personally don't want to constantly remove the battery cover.
plugs everywhere and charge when needed
Also once in a while it's a good idea to just turn off your Droid Inc and charge it up. You'll notice that even if while it was on it said it was full, the phone will continue to charge when you turn it off. it kinda recharges the battery to its full potential. Kinda small alternative to a batterystats.bin wipe

I usually charge it overnight, but I also have two batteries, which I switch out if I forget to charge it or something.
Charge it whenever it gets low.
Still rocking the Incredible with the XDA Premium App.
i put it on the charger when i go to bed, and then take it off when i get up. last all day. battery life with incredikernel/MIUI is awesome. very rarely do i need to charge before bedtime.
If I'm not going to be too far from a charger or if I know I won't be using my phone much, I typically wait till it gets below 40% and then charge up to 60-70% or so. This is the optimal approach to extend the life of your battery. I wish there was a way to configure the voltage or percent at which you want to stop charging.
If I'm going to be away from a charger for longer period of time, I'll charge until the LED goes green. If I'm going to be away from a charger for a really long time, I'll bump charge, but I try to limit the frequency with which I do this because it shortens the life of the battery.
I am using the 2150mAh extended battery by HTC and I have recently (the last 2 days) been powering down and letting it charge over night. Thankfully, I have my DX and multimedia dock to use as my alarm clock.
Just one charge overnight and last all day

I have a 3,500mAh battery, two regular batteries and a battery charger. When my 3,500mAh battery runs out, I swap it for one of the standard batteries while it's charging.
In the school year: charge all night, take off charger at 6am, put back on charger at 11:30pmish. (I have a long day lol) CM7 and Incredikernal treats me very well. I still have about 40% batt left at the end of my day.

So my s2 has been charging really slow, like today it took like 5 hours to fully charge, and when connected to charger if I'm using it it wont charge very well, like the battery will stay at lets say 20% when im using it and charging it, it might even go down more. it used to charge pretty well even if I was on it. Cuz this be the charger, or is my battery messed up?? Im using the charger that came with the phone.

Are you charging through a usb port on your computer or ac? If it is with usb port then yes it will charge at a much slower rate. Also if you have a lot of apps running or backround data going it will also cause your charging to slow down some. I would say through usb without any apps open and backround data stopped It would take a few hours to charge say from 20%. Through AC in the same condition probly 1.5 hours. Try to reboot your phone and then plug it in to charge to see if that doesnt speed it up any. If it does then you know you have backround data moving at a fast rate and that would be your reason to slow the charge down.
Yeah I'm charging with the wall charger, not thru usb

You could try calibrating the battery, maybe. To do that, turn the phone off. Charge to full (make sure it's full, by taking it off of the charger and putting it back on...the indicator should read 100% almost immediately when reattached to power).
When the battery is full, with the phone still turned off, remove the battery for about 2 minutes. After 2 minutes, reinsert battery and restart phone.
Battery will be calibrated. This may not resolve the problem of a slow charge, but will clear 'battery memory' which may have been preventing it from charging completely (and, I suspect, may have inhibited charging).
Good luck!
I was using an aftermarket wall charger and had similar results. Switched to the USB/AC converter that came with the phone and all was well.

Actually, one doesn't need an app to calibrate the battery. If you follow the instructions above, the app is unnecessary. And the phone mustn't be rooted

Hey elflip88, have you found the issue yet?
I have the same problem on my HTC Amaze 4G. It's charging 1% every 3 minutes (adds up to 5 hours)
I'm also using the wall charger...oh damn, I'm starting to think I have a faulty device / battery...
yelp!
For the record Samsung devices are known to be slow at charging so with that considered.... You still shouldn't be at 5 hrs. I would find a battery stats app charge your battery over night and check the chart to see exactly how long it takes to go from 0 - 100. Make sure your batter status is good. Also check the voltage coming into your phone from your charger. There are plenty of battery stat apps in the market that will do this sort of thing. Of course make sure your battery doesn't have water damage of course too lol.

I've had the same problem with mine. But, I can get 1.5 days without charging and moderate usage. Charge it up, drain it, charge it back up then wipe your battery stats in recovery.
This may help if you're using an aftermarket wall charger
If you guys are having issues with slow charging using an aftermarket wall charger, it could be that the phone is charging in a USB state rather than an AC charging state. QuickCharge could alleviate your issues. The cable is inserted between the wall charger and the USB cable that goes to your phone. You can find the product on Amazon. It's the 2nd of 3rd item from the top when you search 'QuickCharge'.
I find that when I fully drain my battery and charge it, it's really slow. Once the phone has enough battery to stay on, I unplugged it and replugged it and it charges normal again.

It's your wifi and your apps using wifi. Turn wifi off while charging. I used to charge 4 hours + on my S2. Reduced to 2 and some change when I turn off wifi.
Also, I struggle to make it through a working day with wifi on. Turn wifi off and I can do 4 days no problem.

I've charged this phone almost every night since I got it (early June) and my battery is still doing outstanding. There are times when charging it over night the battery will set it self to draw battery so it can recharge and not cause harm I believe. There are many superstitious theories and others that "battery experts" say charging over night can be harmful. Overall I don't buy into too much. I always try to unplug as soon as it hits 100% though.

I don't think its true either.. I've charged all my phones like that since I can remember and never had problems with battery, other than software related problems that drained battery, but fixable.. Did you check if maybe it was software related and not due to the battery?

This use to be true on older phones. The galaxy S 3 and most new phones stop charging once they hit 100% it will only start charging again when it drops under 100.
And even before on older phones where it wasn't recommended I did it anyway. No harm done.
I've done this with all my phones, nothing ever happened to them

Overcharging protection, while present, can fail.
If you guys want to have a full charge in the morning, try an outlet timer - or put it in airplane mode overnight (I do that, battery is down only 1-3% after ~8 hours). You could also turn off data + wifi - so phone calls are still there if you are really worried about getting an emergency call in the middle of the night, the call function is still there, but apps aren't syncing and wasting battery and sleep time doing so.
I'm just not comfortable with the fire risk of leaving it in overnight. Sure, it probably won't fail - but if it does ? Why take that chance when there are other solutions ? I just charge it at my desk before going to bed, unplug it when it reports full charge.
It's the same kind of risk as putting a 100W bulb in a 60W socket - sure, you might be fine for a while, you might never have problems - but you might also start a fire when components fail under the stress.

Is there some sort of smart outlet that can stop charging when it reached 100%? I guess in a way the same as the outlets that has a master outlet and able to turn off the rest when the master outlet is off?

I usually let me charge overnight, it hasn't caused any problems for 6 months now.
It is true that your battery being at 100% charge (even if charging to the battery has stopped) is harder on your battery and overall capacity will lower at a faster rate than one stored at 60%. The thing is the difference is negligible over a year. It is technically best for your phone to be charged to 100% and then removed from charge so the battery can drain but we are talking about the difference of wether the half life of your battery is 3 or 4 years. overnight charging is not why your battery has failed.

Lithium Ion batteries are in an ideal state of equilibrium when at 50% charge. If you want to maximize the overall shelf life of the battery, do your best to keep it around 50% charge and avoid the extremes like 0% and 100%. Practically speaking this is tough to do. I am frequently near a charger, so I can unplug around 60% and plug it back in around 40%. The high amperage chargers that come with the phone can add 20% in about 30-40 minutes.
So the answer to your question is, the less time your battery spends at 100% the better to maintain the quality of the battery.
LOL, I keep phone on the charger all the time. Then again, I usually have the screen on most of time.
The only danger I can think of is if someone comes out with a kernal that does SBC which can give batteries more charge, but can also damage the battery if overcharged. I haven't kept up on all the kernals, but I don't believe anyone has made any with SBC.

50% is for storage. When in use it is optimal to charge to 100% and recharge between 10-20%, ideally at the 15% warning, which is why it's there. Charging to 100% overnight wouldn't have a huge impact on battery life for a li-ion unless you left it plugged in for several days straight. All newer good quality cellphone and mobile device li-ions have a voltage regulator and charging circuit built in. When the battery reaches 90% the voltage regulator drops the input voltage so its receiving less power til 100% once it reaches 100% the charging circuit opens and stops charging the battery, once the battery begins to discharge again while plugged in the voltage regulator switches to "trickle" charge mode which puts back a small amount of power every minute or so. When "trickle" charging the input power is so low the battery can actually drain while still charging if its being used. These are safety measures to prevent damage to the phone and battery and lessen the risk of the battery exploding, but it also helps prolong the life of the battery by preventing it from constantly overcharging if you forget to unplug it or charge over night. Hope that helps explain a bit about how charging works. Its also better to charge the battery at lower amperage outside of the device. Optimal charging for a li-ion is around 750ma on an external charger or while the device is off.

I do it when I can't get a full charge before bed; but I also wake up 2-3 times per night and tend to unplug it once I notice it's at 100%. I've read that once it reaches 100%, if it stays on charge for a certain amount of time it will switch to battery and drain, then charge back to 100% after a certain percentage is drained. I would say that's the case as I woke up one morning and the phone was at 92% charge and was in the process of charging. Battery info said it was charging on AC and the graph showed it went to 100% then back down.

I do use that guide. My signal is terrible and is what drains my battery. I really don't believe that is related to any app running wild and draining my battery because from completely dead to 100% takes about 2.5-3 hours with me using it, WiFi on, brightness at 100%, etc; I can also easily get over 2 days without a charge with light use... It would be more but my lack of signal accounts for an almost 1.5% per hour idle drain. Good signal areas I'll drain less than .5% per hour with no use/app changes outside of having a strong signal.
Weird...
When your phone charges to 100%, your phone knows to stop charging, mine always stops charging when is says "reached 100%". I just leave it on the charger and it stays steady at 100 until i take it off.
It shouldn't effect the lithium ion, either.
I thought that was the special thing about lithium ion?
They don't wear down?

Bought some cheap batteries on Amazon, I charge whenever I want, however I want (typically overnight, all night). If I ruin the battery, so be it, I can just pop it out and replace it in 5 seconds. This is the real advantage of having a removable battery.
I've always left my smartphones on the charger overnight. Seven years going and haven't had any issues. I do tend to replace my battery after 9-12 months of use though.

I've read that once it reaches 100%, if it stays on charge for a certain amount of time it will switch to battery and drain, then charge back to 100% after a certain percentage is drained. I would say that's the case as I woke up one morning and the phone was at 92% charge and was in the process of charging. Battery info said it was charging on AC and the graph showed it went to 100% then back down.

This sums it up. Per the article linked earlier in the thread about charging li-ion, it sounds (relatively) trivial for the device manufacturer to implement a charging cut-off after the cells reach a specific voltage level. Once the cells drop to a certain level they're safe to charge again, and the cycle starts over. I don't imagine it's great for the battery to sit on that recharge cycle, but it's not going to over-charge and become a fire hazard.
I imagine external battery chargers might be a little different. That $3 battery & charger from eBay isn't going to have the same safety regulations as a major manufacturer like Samsung.

An interesting tidbit from that article.
Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery.

I'm pretty sure a $600 phone can handle any of your charging blunders. Relax kid.
We're not dealing with Nokia's anymore.

Avoiding full charge has benefits, and some manufacturers set the charge threshold lower on purpose to prolong battery life.
Lithium-ion does not need to be fully charged; a partial charge is better.

All the other comments say not to charge over night...

I charge mine overnight with no issues.

I just called Samsung and they highly recommend me to not charge it over night

I get the general concepts that the article presents, but it doesn't really address any advances in charging methodologies that newer devices could add. It reads like it was designed for 'dumb' devices such as cordless phones, rechargable power tools, etc. For instance, it says never to charge with the device powered on. Yet Windows Phones (at least my Lumia 800) won't charge with the device off...plugging it in automatically boots the phone up.
Our phones obviously have more advanced power circuitry, such as being able to hold the power button in and have the device power cycle no matter what state the phone is in, and I assume it applies to other parts of the phone as well.
