Is it OK to leave the phone charging over night? Or are you only supposed to charge to 100 and then pull off the charger? If anything, what's best for the battery?
Sent from my Nexus 4 using xda app-developers app
Yes. It's ok. The phone stops taking power from AC.
But if you leave for more than 13 hrs the phone self destruct. It is a new Easter egg in Jellybean 4.2
Charge as you please. It's virtually impossible to damage the phone / battery through charging (disclaimer: original charger & providing nothing is defect), it stops charging when full.
Just avoid leaving it totally dead for longer periods, that's not good for the battery + avoid rapid temperature changes.

What happens if I leave my battery charging over night and I don't unplug the charger once my phone pops up the message telling me to do so. Will my battery overcharge and fail? Or its out safe to leave it plugged on once charging is done?

Your phone will be fine, there are fail safes in place to prevent over charge (and fire/explosion). Its just a "convenient" notification to let you know the phone is done charging.
On a separate but related issue, I don't suggest leaving it charge more than 10 hours at a time, since the battery keeps topping off the charge, and in my experience this degrades batteries a bit faster.

this.
Constant topping up will shorten the battery life. Not something to be annal about but don't do it too often. It also does not mean you have to fully drain your battery before charging, nor that you have to set an alarm so you take it off charge as soon as it read full.
Wait, so I should not charge my phone en route from work to home? About a 30 minute drive... not enough to fully charge the phone, just enough so it doesn't die before I go to bed.
I thought batteries did not have "memory" and that you could charge them however.... is there a good source to read?

Care to back up that statement with some sources?
Heat kills Lithium based batteries.
A quick rate of charge or discharge creates heat.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
(From the article)
The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible.
should be balanced with this (from the article as well)
batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.
My recommendation is to keep the battery as full as possible at all times and do a full calibration cycle once a month. Done.
If you want the battery to last longer stretch the calibration to once every two months... However the phone will be obsolete before noticeable shortening of the battery life from doing 30 day calibrations. PLUS THE BATTERY IS REPLACEABLE ANYWAY. So, honestly, who cares?

If your battery overcharges and fails, your battery is a danger to you and everyone around you anyway; no matter what charging methods you use. A properly working lithium ion battery cannot be overcharged.
I suggest reading up on how float charging works.

This is normally what I do, so it charges 5-7 hours a day, I don't normally kill it during the day, but it does get pretty low

My phone is samsung j7 prime ....
Yesterday i charge the divise over night ...
Does it will effect my battery?
Hi all im about to pick up a n7 and join the club ..
But i'd like to know the first time charging pattern ? If i remember right i have to fully discharge to 0% and then overnight charge ?
Oh and while were at it how long one full charge takes ?
Thanks.

With the new lipo batteries you should AVOID full discharges. Instead, charge the device to 100% before using, discharge to about 5%, turn off, then charge to full while off. That should condition and calibrate the battery effectively.
Also, a charge takes roughly three hours to full for me.

Manufacture doesn't recommend full discharge, they just recommend a full charge before it is completely discharged. What I did was discharged through use to about 30% (out of box it was 55%) then did a full charge.
As far as how long it takes charge, it really does depend on your power. Every house and every location get its power differently really. It also depends if you are using the stock provided charger as you're supposed to, if you're using usb from the computer, whether you are going through a power converter/ u p s or even if you are using a non standard power output to usb. On know my full charge was about 2.5 hrs from the 30 percent to 100 percent, using the stock charger to outlet through uninterruptible power supply which has a built in power converter/balancer because my electricity is crap ( unincorporated area, old house, old wiring ).
Really though you don't have to worry too much about lithium ion batteries. You really don't want to give it a complete discharge, based on the existing evidence. Apparently this causes a relatively significant shock to the actual chemicals the power the battery. However many people say you do not want to completely charge the battery either, but most battery service management programs, the actual firmware that keeps the batteries going, will stop a charge at 99 percent tell you it is 100 percent and no longer charge above that for this specific reason.
if you look around to the community, many people recommend that you fully discharge battery, after using a program like battery calibration https://play.google.com/store/apps/details?id=com.nema.batterycalibration and then charge fully to 100 percent anytime you change ROM so the same could be said with a brand new stock unit. Also let's be honest, your device is going to last 2 maybe 3 years. How much damage can you really do but discharging in a few times in the time? also the batteries aren't all that expensive so even if it does significant damage it is still repairable?

Thanks guys and to be specific for the charging time part i will be using stock charger and not usb so just a quick recap charge to 100% discharge to 5% and recharge to full ?
And if it takes me 4 hours id be satisfied because my sensation that has 1900mah takes about that much time and the n7 is more then double of it ..
Can't wait to pickup this beast hope ill get a perfect unit

Use it to 5 percent charge, then recharge to 100 percent
Sent from my rooted Nexus 7 via xda-developers app.
Just reiceved my N7 today. It only had about 5% charge. I've had it on the charger for 5 hours and its only at 75%. This doesn't seem normal.
Hey people.
So I have an issue with my battery on my N4. I left it to charge over night in the wall charger and when I woke up my phone was stuck at 66% charge. I unplugged the charger and plugged it back in. First it's showing that it's charging via the AC but changes to USB after a few seconds. I rebooted my phone twice which fixed that problem. However, charging is very slow now (so slow that the battery drains faster than it charges) and when my phone is not charging the voltage keeps jumping up and down.
i.e: at 53% charge the voltage is at 3734mV but jumps to 38xx mV all of a sudden and then jumps back down again (not the first voltage but to a different one again such as 3778mV). Is this behavior normal? I don't think so.
So should I be worried or what can I do to fix this? Maybe fully discharge my phone? But I'm worried that this'll affect my batteries life in the long term.
I've had this phone for around a month now and I'm fairly scared that somethings wrong with my baby.

Is it possible to ruin my phone's battery due to overcharging? I charge my phone overnight no matter what percentage it is on, I still charge it I know this is bad, but can this ruin the battery? thanks
You should be able to charge as long as you want w no problems as long as you're doing this in a cool or room-temp environment (rather than say leaving it alone in a car charging at high noon w AC off, windows down & no sun shades on the windshield). If you have your phone charging in hi-temp conditions too long\often your battery swells & you get gradual irreparable damage.

If u make a correct use of your battery it won't get damaged. Extreme overclock, overvolt, etc can ruin your battery, but if u charge it every day because ur battery is empty it's ok, and u won't have any problem.

thanks man =) thanks to the both of you who replied
Normally, when your phone reaches 100 % full battery level, it stops charging and starts discharging. At around 95 % level, it starts charging again. This all takes a toll on the battery, especially over a long period.
If your phone's battery is at or above 50%, leave it alone or turn it off for the night.
I have an external battery pack for use during the day time, just for situations like this.

I don't think that's correct. It should switch to a trickle charge, which won't harm the battery, not stop charging completely.

What I spend a lot of time charging the phone through USB? I leave it on charge at work plugged into the computer through USB as there are no free plug sockets. My battery just seems to be getting worse and worse over the last couple of months... Could this be the problem?

It'll automatically stop charging itself when it's full, it's impossible to overcharge a modern cell phone battery these days. They are a bit more computerized than the old nicad batteries from back in the day. It's actually healthier to give lithium batteries partial charges at a time instead of draining to zero percent and charging to 100 percent.

I doubt it. Could be a faulty battery, but more likely to be apps draining it in the background. Install BetterBatteryStats and see what is using the battery.

i'm using app called full battery & theft alarm. i always charge my phone during sleep, and this app will wake me up to disconnect the charger if the battery is full.
i hope this will prolong the battery life
How do you know your battery is getting worse if it's always charging?
My personal experience is the less you charge it, the better it will perform. However, when you DO charge it, make sure you are less than 30% battery and charge it to 100% before removing it.
For me it's easy, I basically charge my phone at night when I go to bed and that's it. I easily get through an entire day on this phone, though I admit I usually only have about 2-1/2 hours screen on time (I mostly use my tablet when I am at home)
Is it safe to charge my phone overnight on the charger it came with?
Sent from my Verizon LG G2
Can't see why not. I've done so many times. It didn't get overly hot at all, and after it was done charging it felt even cooler. It even gives you a ping when its done and changes the LED to green, so in case you notice just pull it out. Try to avoid charging unnecessarily though, for the batterys sake.
Lol that's why I'm asking the question. Cause I'm asking about charging while I'm asleep.

The way a charger works is FIRTSLY it supplies the hardware with power, and if it's a 5v 2amp charger and your playing a game, say the phone uses 4watts, then we still have about 6watts to the battery.
When you're charging it without using it, it will use LESS than 1watt, and when the battery is charged, it only charges the battery when it needs to, but the charger will power the hardware.
tl:dr yes, modern chargers are safe to not disconnect .

check this thread out its pretty helpful.
also, apple has a little helpful page
http://www.apple.com/batteries/iphone.html
highlights:
partial discharges are more beneficial than full discharges
ideally, you would charge while phone is turned off
use 20%-30% at a time
keep phone cool
ive also read elsewhere that its best to keep your phone between 40-80% charge, and after 30 charge cycles to do a full discharge (run it til it shuts off) then fully recharge. this process simply helps recalibrate the accuracy of the battery reading. dont worry about damaging your battery by letting it discharge until it shuts off, the manufacturer designed it to shut off before any damage is done.
Thanks guys. Just curious cause you hear so many different answers from everywhere. Loving this phone. Got it for free from best buy last week!
