    If I charge over 100%, what happens? Is this safe or dangerous if it happens often?

    If by 'overcharging' you mean leaving the phone on the charger too long, then no. You can't overcharge a battery that way. Either the charger or the phone has a gizmo in it to stop charging when the battery is full. If you charged it with a higher voltage than the regular phone charger then it could get overcharged and damage the battery.

    Yeap, battery technology has come a long way. They're "Smarter" batteries nowadays.

    So... I only charge my phone when I am asleep, that is after midnight. And I pull out the cord after I wake up. I always fear that I may have overcharged it (for nearly six hours). Do you guys mean it won't do any harm to the battery?

    I cant wake myslef in midnights to just pull out the cord.. :3

    Once the battery is charged to 100%, the charging stops automatically. It won't keep charging your battery post 100%. I have kept my phone charging overnight several times but nothing happens. So there is nothing to worry about.

    I don't know if that's 100% true, the charging may stop but there is a trickle that happens continuously. I thought it was common knowledge that unplugging a charger when your battery is full extends battery life, but maybe I've been believing a lie for many years.

    Yes I want this addressed too, for sure at that.

    The 1st 920 I had got the battery swollen up, thanks to NOKIA Care I got it replaced. I always thought it was due to overnight charging, now it seems like I had a defective model.

    You can't overcharge your battery. If this was a problem, they would note it in the owners manual or on your phone, or the fast start guide..

    Keep in mind, no matter how careful you are with your battery usage, after about a year and a half it will have about 80% of it's original capacity. At three years it will have 50% or less of it's original capacity

    I always remove my charger from my phone after an hour (fully charge). I do not leave it overnight.

    Windows Phone charges the phone to 100% then it stops charging and wait's for the battery to go down to 97% to start charging again, and this happens over and over again.

    When I travel I usually leave my phone on the wireless charger overnight so it will be ready in the morning. You can see the charging plate led cycle once the battery is at 100%. So the phone/battery combination knows when it reaches full charge.

    OK, everyone needs to learn that you won't damage your battery by charging it whenever. If you let it constantly run down, and then charge up, you are over stressing the battery, and that ends up doing more damage than you think you're stopping. I put my phone on the charger at 90% for 8 hours when I sleep. I have only noticed a decrease in battery life after I updated to the GDR3 Preview. Get a grip and stop following these ridiculous tech tips. YOUR PHONE WILL BE FINE IF YOU CHARGE IT BEFORE IT GOES TO ZERO.

    Which is why I hate sealed batteries. If I have a phone I want to keep for several years, the average consumer needs to have it sent off to get it worked on once holding a charge becomes a problem. Most will just get a new phone.

    Just evil. Good business model, but evil.

    I used to feel the same way. However, the only device I had where the battery failed after a little over a year was a BlackBerry 9000, which had a removable battery.

    I also have a friend who still uses an iPhone 4S he got back in October 2011, and it has not had battery issues.

    Speaking of that, I have an iPad 2 from September 2011 with no issues battery wise. So it really depends. And quite often I drain my iPad battery to zero.

    We have an original iPad in my house which I bought in April 2010. It's now basically a toy for our three year old and was a great potty training tool, with still great battery life.

    That was one of the horrible days with the 920, the camera panel started bulging out from bottom, i 1st though it was a bad glue, but then **** happened, the front screen started bulging and by the time i gave it to nokia care, its screen was bent, like the lg g flex(but outwards).

    Here's a link about charging a lithium phone battery. It's talking about Apple. I didn't find a Nokia or HTC article doing a quick search, but it's the same:

    well i got the 520 for a few months now,i always charge it at night while im sleeping,in the morning when i wake up the battery is full and device is cold-if the device was hot it would be a clue of overcharging,so nothing to worry about. :)

    Overcharging can lead to a state where your phone does not run. Then, simply not charging for 24 hours usually fixes the problem. I have observed this issue on devices left on their charger for 2-3 days.

    Okay, I'm an electrical engineering major in school so I can explain this. LiON batteries and LiPO batteries have charging circuits that prevent them from being overcharged AND drained (as in, the phone will leave some charge left in the battery when it is so low that the phone turns off as to not damage the battery). Overcharging does not hurt the battery in the sense that you are putting too much current and voltage into it as much as the phone will keep charging the battery over and over again. What that means is that the phone will charge the battery to 100%, the battery will naturally discharge over time, whether the phone is on or not, and lets say the manufactures have it set to charge the battery when it gets to 90% capacity again, and then it will start charging again. So basically, when you have your phone constantly plugged in, it will charge and discharge and repeat this over and over again if its full. This will eventually kill the battery life as LiON batteries have a certain amount of charge cycles in their lifetime. The average LiON battery will usually last about 1-1/2 to 2 years in general. Unfortunately, battery technology is the limiting factor in all mobile devices and its the one technology that has not advanced anywhere as fast as other technologies. I mean, the last breakthrough was LiON and that was in the 90's. WE NEED NEW BATTERY TECHNOLOGIES!!!!!
