The maintenance of mobile battery usually starts from the first time of charging which influences battery service life. Normally, the first time of charging should be 16 hours, but no more than 24 hours, otherwise, it would destroy the battery. After the first charging, remember that letting the battery discharge totally, then let the battery charge, around 5 – 6 hours per time. After a few times of charging and discharging, the using effect would reach the best.

 

 

Be notice that, not to stop using the battery which is used at a half or is already used for a few months. The standard of battery service life is one year. After one year using, to discharge the battery every two months, it is good for extending the working life of it. While no need to recharge the new battery every time after using. Finally, please pay attention that do not continue to use the battery which is oil spilling. Normally, to charge the mobile, it is better to use the original attached charger, but not the multi-charge one.

 

 

Once the jewelry, keys or something like bead accessorizes touch with the electrode of the battery, these things might become very hot by forming a circuit and it is harmful to human body. Avoiding oil leaking by accident, the charged battery should be placed properly. Once the battery is taken out from your mobile, it should be kept inside the protection bag. If the battery will not be used for a long period, it should stay in the saving bag and keep it in some places which are dry and dark. Do not leave the battery on hot surfaces (over 60℃) or in the sun. Besides, using the lithium battery in low temperature condition could not make sure the best stand-by time and speaking time.

 

 

When you are using GSM mobile, be attention that this kind of mobile has functions of locking the mobile itself and the card as well. If user forgets the password after locking the mobile, it can be solved with dongle. However, since the self-protected function of GSM-SIM card, if the PIN is lock which means the card is locked. After inputting wrong PIN for three times, user will be asked to input PUK, after ten times with wrong PUK, so sorry about that, the card is over. For examples, Sony Ericsson mobile would show ‘SIM CARD BLACKED’, and Panasonic G500 would show ‘SIM ERORR’ which mean the SIM card has been destroyed. Therefore, ‘look before you leap’ when you want to lock the card with password.

Something as rainwater, moisture and the liquid with mineral would corrode the circuit board. Do not place the mobile in somewhere which is not clean or with dust, since it might destroy the removable parts. It would be a good idea to get a leather case for protecting the mobile. Do not use drastic chemical products, cleaning agents to clean it.

 

 

Hot temperature would reduce the service life of electronic devices and destroy the battery. Placing the mobile in somewhere with too cold temperature, with the increasing of mobile temperature, humidity will be brought out to inside, so it would probably destroy the circuit board.

 

 

Do not use GSM mobile next to the programmed – Control Telephone which is being used at the same time. Since the interferences between mobile and programmed – control telephone is quite serious, and it would influence the speaking quality of both.

 

 

Do not beating or vibrating the mobile rudely, it would destroy the inside circuit board. Keep the mobile and its components away from children, in case the mobile would be ruined by accident.
