Is it possible to charge your phone too much?
- Hey Everyone, I just got a charger for work and I'd like to use it but I'm afraid that you can charge your phone too much. I have heard so many different things and I know that todays batteries are much different than the batteries of yesterday.
I had heard previously that you should charge your battery when its pretty much drained to keep it lasting longer. I usually just charge mine every night, thats what I've always done.
Then I heard that these batteries can "learn" the first two weeks you get them (I have a new bold). I think that's a load of bologna though, they don't have memories.
Ok so I need some educated people to help me out here.
Thanks!07-07-10 09:18 AMLike 0 -

- With older batteries this was much more of an issue, but with today's cell batteries it's not so much of an issue. Charge away!07-07-10 10:07 AMLike 0

Should I keep going?07-07-10 10:08 AMLike 0 - Yes, you CAN overcharge a cell phone battery but not with the charger that came with the phone or one that's made for the phone. Overcharging requires a charger that supplies a voltage that is too high.
I destroyed a battery in a phone using the USB port on my PC, the battery was almost completely dead and apparently the PC USB port tried to charge the battery too fast, it swelled up like a balloon!
I've found the USB port is safe if the battery is about 50% charged or more but it's always safer to use the proper charger.Last edited by xs11e; 07-07-10 at 10:18 AM.

- They'll be safe, I'm sure. Read the tiny almost invisible print on the part that plugs into the wall, compare output voltage with the charger that came with the phone. For most BBs, that'll be around 5v.07-07-10 10:34 AMLike 0

- SevereDeceitSDYou have entirely too much time on your hands, you could of easily just answered the question instead of making yourself look like a fool. Let me break it down for you since you seem to have a hard time understanding. There is over 2 million members here, not everyone will search, just the way it is. Now run along...07-07-10 10:42 AMLike 0

- The only negative effect I have seen of Lithium Ion batteries is when they are constantly drained. I plug my bb in as frequently as I can. In the days of Nicad (nickle cadmium) they had a habit of losing their ability to accept a full charge if not depleted completely the first 3 or 4 chargings. Just don't drain it completely and you will be fine.

This had nothing to do with the USB port, there is no danger of overcharging the phone or "charging it too fast" either from the USB cable or the wall cable.
What you experienced was a failure in the battery protection circuit and quite possibly the BB hardware too. A LIon battery will actually dissipate voltage over its threshold to keep within it's limits but if this fails or too much current is applied too quickly then you get the problem you experienced.
So bottom line, no, you cannot overcharge the battery and USB or wall chargers WILL NOT damage the battery no matter how long they are plugged in for unless you have a hardware defect either in the phone or the battery itself.07-07-10 10:54 AMLike 0 -

Charge it often and keep it high.
HOWEVER...
If you intend to store an unused LIon battery for more than a few days outside of a device then reduce the charge to 50% before storing it. A fully charged LIon battery will drain away to nothing very quickly whereas one with a 50% charge to start with will hold that for a long time.
Make sense? I know not really, but there's a whole ugly reason behind that.07-07-10 10:56 AMLike 0 -
- Good info Radius, and I'm sure another charger would do the job Pi if you are lucky enough to find one with identical specs, but it's so painful to try and read the damn thing! Miniature font, black on black background. Ouch.

You can test this for yourselves by switching the phone off via the red call hangup button and starting the charge process. You will see the LED flasing gree/yellow on/off about every 2 seconds during the charge process.
When the battery is fully charged the LED will go on solid green indicating that the phone knows that its battery now has a full charge.
A further check woudl be to feel the temperature of the back of the phone (where the battery lives) whist charging and note the warmth of enegy flowing. A half an hour after the gree LED goes on solid, the warmth will have gone.07-07-10 12:09 PMLike 0
