Prolong cellular battery life

Try avoiding frequent charges. If possible charge only when the mobile has discharged up to a very low power, say 20%. This increases battery life. For now allow your mobile to drain out completely, then follow the above approach, you may observe an improvement in the battery life. If still it does not improve, you need to visit a servicing centre.

nokia 2330c calling time battery empty & when restart phone battery full plz provide me this problem's solution ....

Hi,the reason why your laptop is telling you to replace Battery is,you have killed your battery without knowing by Charging it always,since you have constant power supply,you should at least after getting a new Battery,discharge it four to five times a week longer life of battery,by these i mean,unplug cord from mains let power drain to 5% or 10% before charging again while working and if fully charged and you are not making use of it disconnect and if you want to make use of it use battery instead do not connect immediately to mains until power drains from battery.Just like your mobile phone,you only charge it when need be(ie. when Battery is Low).

If both the charger and the battery are warm to the touch, the battery is probably charged.

The low battery level warning level is learned by the phone. To train it, allow the battery to run down once until the phone stops working, then recharge it.

The best way totest the charging operation would be to try using the phone. Fully charged you should get about 6 hours of talk time from a fully charged battery, and at least a week of standby operation.
