All batteries, whatever their chemical composition, deteriorate over
time, although recent improvements in battery technology and the
introduction of lithium batteries have eradicated many of the problems
associated with cell phone batteries. If you find your cell phone
battery doesn't seem to hold a charge for long, then there are two
methods you can use to refresh your battery, depending on the type of
battery.
Instructions
-
-
1
Turn off your cell phone. Remove the battery cover. Cell phone battery covers usually slide off or unclip.
-
2
Remove the battery from the cell phone. You need to lift it out of the battery compartment using your fingers.
-
3
Check the label on your cell phone battery to determine if
it's nickel- or lithium-based. It says NiCad, meaning nickel cadmium, or
NiMH, meaning nickel metal hydride, if it's nickel-based. If it's
lithium-based it says Li-ion, meaning lithium ion, or LiPo, meaning
lithium polymer.
-
4
Replace the battery into the cell phone. Put the battery cover back on the cell phone.
-
5
Complete the steps in Section 2 if it's nickel-based. Complete the steps in Section 3 if it's lithium-based.
-
6
Turn off your cell phone. Put your battery on charge in the
usual way. Disconnect the charger once your cell phone indicates the
battery is fully charged.
-
7
Turn on your cell phone. Open as many applications on your
cell phone as you can: Play music, videos and games. Browse the Internet
if you have the capability. You must discharge your cell phone battery
fully to refresh it. Let the battery discharge until your cell phone
automatically turns off. Wait for half an hour or so, then turn on your
cell phone. It powers up, despite having appeared to be dead half an
hour earlier.
-
8
Open a few applications, not too many, because you need to
drain the remaining energy slowly. Let it operate until it turns off
again. Wait 10 to 15 minutes, then turn on your cell phone. If it
doesn't turn on, your battery is fully discharged. If it powers up, let
it operate until it turns off, then repeat again until the cell phone
doesn't turn on.
-
9
Let the battery rest for 15 minutes, then plug in the
charger. If your cell phone turns on when you plug in the charger, turn
it off. It's important you charge the battery while the phone is off.
Leave the battery to charge. It takes a lot longer than it did
previously. This is because the crystals in the nickel-based battery
have broken down during the full discharge and can now retain far more
energy.
-
10
Unplug the charger from the battery once your cell phone
indicates it's fully charged. Turn on your cell and you will find your
battery is refreshed and lasts much longer.
-
11
Turn off your cell phone. Remove the battery cover and battery using the same method as before.
-
12
Wait a couple of minutes. Insert your battery into the cell
phone battery compartment. Replace the battery cover and then turn on
your cell phone. Let it power up, then turn off the cell phone and
remove the battery cover and battery. Removing the battery, then
replacing it, can reset lithium batteries because each time the battery
is replaced and the cell phone is turned on, the electrical current
flowing between the two effectively "kick starts" the battery.
-
13
Turn off your cell phone. Charge your battery in the usual way. Wait until the cell phone display indicates the battery is full.
-
14
Turn on your cell phone and use it until the battery display
says it's three-quarters full. Charge your battery: You don't need to
turn it off. Let it charge until full, then use your cell phone.
-
15
Repeat the procedure one more time. Lithium batteries,
unlike nickel batteries, operate better if they are charged for short
periods. Charge them as often as you can, but remember to disconnect the
charger once it's charged. You will find your cell phone battery is
refreshed and operates better and, if you are unable to charge it for a
while, you will find it lasts much longer.
