Phone won't charge

1280 CHARGING IC SOLUTION

When the phone gets wet i gave taken the phone apart and used a hair dryer to dry it out.
you could have shorted the terminals on the microchip board.

Hi, The Li-ion battery cahrging circuitary is some what complex. For most chargers, the charging procedure is divided into three main phases: ? Pre-charging phase ? Constant-current-charging phase ? Constant-voltage-charging phase In the Pre-charging phase, it utilizes low charging current to protect the battery. However,in most recharging situations, the charged batteries still have some voltage remaining, so the charger does not need to apply this action, and just passes it on to the next charging phase. The constant current and voltage charging phases are the main charging phase for recharging the batteries, where most of the charging energy is transformed into the battery. The maximum charging current for a battery depends on the battery?s rated capacity. For example, one battery rated 700 mAh usually can be charged at 350 mAh to 400mA, for faster charging effort. When the charged battery is Li-Ion, in the last charging procedure, the microcontroller normally maintains regular charging voltage while monitoring charging current to determine when the charging procedure should be completed. When the battery is fully charged, most of the electrical energy is converted to thermal energy, which can result in high battery temperature. In this case, the temperature monitoring function will be added for the solution. But since most Li-Ion batteries on the market also have an over-charging protection function, the temperature detect function is rarely used. So it is better to get your phone charging circuitary checked at a local store rather than to make a charger,coz both may cost you almost same. all the best my friend. regards sreejith

Desk top charger could work if you think the battery is still ok...the white spot next to the gold contacts on the battery indicate if the battery is dry. The safest solution is to try another battery to see if the phone is still ok
