If the lithium-ion battery in your smartphone has seen better days, there are a few things you can try to bring it back to life before spending the cash to replace it.

* One of the simplest is allowing the battery to die completely and then charging the battery for two to 

three days while the phone remains off.

Other methods are simple, using household items to repair a weak battery. For both these methods, turn the phone off and remove the battery before beginning.

'''Cold Storage'''

Wrap the battery in newspaper and then two layers of plastic wrap. Put the battery in the freezer for three days and then put it in a cool, dry place for two days. Replace the battery in the phone and charge it. Placing the battery in a cold area reduces the leakage current, which increases the power.

''' Oxidation Removal'''

Using an eraser, gently wipe the metal contacts on the battery and inside the phone. Prolonged use creates oxidation, causing a weak battery and a bad contact.
