If the lamp light doesn’t turn on, you know there’s an issue with the outlet and can try plugging your phone into a different outlet.

You can also borrow your friend’s charger to see if it will work for you. You can try changing the cable first, but if your phone still doesn’t charge, try your old cable with a new adapter (if you use one). If your phone charges with a new cable or adapter, you can skip the rest of these steps and instead charge your phone for a while.

If moisture has gotten into this port, it may cause damage to your phone or prevent you from charging the battery until it is dry. You can set it upright with silica gel packets so the moisture drains out and dries. Make sure the pins here are intact. If they are broken, you may not be able to charge your phone’s battery. Fixing this yourself might damage the phone, so take it to a service center.

Do the same with the negative wire. Do not connect opposite polarity, positive to negative, because this can short out your cell phone battery. Most cell phone batteries have more than two terminals, use the ones that are furthest from each other, or the ones on the outside. The center terminals are not to be used.

Place them in a cool, dry place, away from any water or heat.

Do not use paper bags or foils as water can easily penetrate these materials. For the sealed plastic container, think of a Glad or Rubbermaid container.

By exposing the battery to low temperatures such as the inside of a freezer, it allows the battery cells to recharge a little, enough to hold sufficient charge to be connected to a phone charger.

Do NOT use the battery while it’s still cold.
