Re: slow or fast charge

Yes, the amperage your charging at determines charging time. The higher the amperage, the faster it charges. Your battery is rated in mAh or milliamp hours. One Ah means the electric charge transferred by a steady current of one ampere for one hour. A mAh would be 1/1000th of an amp for one hour. If your battery is a 1500mAh battery it means 1.5 amps for one hour. This charge current should not exceed the rating of the battery. It would cause possible excessive heating and possible a fire or explosion, especially on newer more volatile batteries like lithium polymer batteries. The life of the battery charge when fully charged will be similar no matter how you charged it, but slower, lower amperage charges will maintain your battery better than quicker, higher amperage charges and help extend it's life to its potential.

Re: slow or fast charge

I think it's the amount of Amper... Some laptot offer only 100mA on USB (slow Charge) instead Desktop PC can offer 500mA (fast Charge). The life time of the battery is the same (i suppose) with the fast or with the slow Charge. the difference is in power consumption.

Weird Battery life issue.

It's possible that your battery needed to be replaced. Since if the battery is not taking any charge or the battery depletes fast.. that basicly signifies that battery needs to be replaced since sometimes we can't avoid for the battery to be overcharged or we often charged them to often even if the battery still isn't drained yet. That causes for the battery to be defective or overused.

My g1 will not charge fast like it use 2

Have you tried recalibrating the battery? To do this you use the phone until it completely runs out of battery and switches itself off. Make sure it has completely run out by continuing to turn it back on until nothing happens except a red LED coming on. Then charge it while it's off until the green LED has been on for 2 hours. Hopefully this will improve your battery life.

Just wondering how to connect it to a computer?


The Samsung SCH-i730 doesn't have a USB port, but it has a different port that underneath the phone itself. You need to use an adapter so that you could connect it to the computer. Look for the adapter SCH-i730 Lil Sync USB connector.

There could be a possibility that the battery is not working correctly. To isolate this, try to use another battery to see if you will get the same problem.

NOTE: To take care of the battery, never charge it if it's not running out of charge. Never unplug the charging battery if it's not fully charged.

Sidekick / Hiptop 2 won't take charge

The battery might be an issue. Sometimes with lithium Ion batteries, tehy just act retarded and need to be jump started from the dead. Buy a battery from any vendor and test it out. If it doesnt work you can always return it.
