I forgot to charge my Motorola Razr last night. Today, I noticed it had the flashing "Low Battery" symbol, and turned it off. Later in the day when I tried to turn it back on, it was not responding and did not turn back on. When I plugged it into the charger at home, it did not turn back on. I've left it on the charger for over an hour now and it's still not responding. A friend of mine suggested I leave it on the charger overnight and then try it again in the morning, since when a phone dies of low battery, it needs more time to recharge. Does this sound like a suitable solution? Is this circumstance common? If so, how did you fix it? Could it be my battery that is faulty? Thanks in advance.
