Q&A for How to Revive a Cell Phone Battery

The first thing to do for any electronic device that has liquid damage is to remove its power source. This will stop your device from becoming damaged further. For phones, this includes both the charger and the battery. In many cases removing all power sources successfully may prevent damage from occurring to your device. For many newer devices, the battery is not user-removable. In cases where the battery is not user-removable visit your local repair shop as soon as possible in order to have the device professionally disassembled and inspected.

In most cases, this will not help. Modern mobile devices are well sealed, which prevents the rice from making its way inside the device in order to absorb the water.

If the battery is bulging, consider getting a new battery. Using the bulging battery can cause damage to your device and other unwanted problems.

The battery is defective. Replace battery and do not try to charge the old battery.

No. A new battery is inexpensive, and taking these steps with a damaged battery could result in injury.

The battery is dysfunctional. Try getting a new battery. They're usually inexpensive, unless it's an iPhone or iPad battery.

In general, the terminals will be marked with symbols: + for positive and - for negative.

No, you shouldn't as that can result in injury and the battery is beyond fixing.

The fridge is not cold enough; do the freezer method. But if the battery is FWT or bulged at all, do not try any method on this article as it could result in injury.

Your battery is dysfunctional. Replace it with a new one.They're usually inexpensive.

Get a new phone. You probably have an iPhone if you can't remove the battery. Try going to the Apple store and asking what they recommend.

Try going to a battery store. The technicians there can often replace phone batteries.

Use the furthest ones, and not the one in the middle.

It can no longer hold power, which means the battery is bad. You'll need to purchase a replacement battery.

You can't remove a built-in battery, at least not on your own. Take it to the manufacturer or your service provider.

If your battery is in the least bit damaged physically (bulging or mishaped), won't hold a charge, or becomes warm to the touch while being charged, then here is no mechanical repair or electrical repair that should be attempted at all on your device's battery! These are lithium ion batteries, if handled or disposed of improperly they will explode or catch on fire! It is fairly inexpensive to replace them and to have a tech do the work. Replace the battery with a new one and dispose of the old one properly and your device will go on serving you well.

Take it to your nearest phone repair store if you can. Your phone battery might have died, so don't try to jump-start it.

Use the same method - this is explained in the jump-start section. Place the negative wire to the negative terminal, and attach the positive wire to the furthest positive terminal. If the other terminals are in the center, use the ones on the edge.

No, wait until the battery has warmed up til room temperature. Do not use it while it is still cold.

Perhaps it could be from the phone's IC (Integrated Circuit). Try changing it.

No. A 9-volt battery is preferable to jump start the cell phone battery. Make sure you use electric tape, thin electric wire (red wire is positive + indicated on battery and black is negative - indicated on battery). Charge it for 30 seconds and do not exceed 40 seconds. Check by touching the battery to see if it is getting warm or hot. If it is, then remove the battery.

Immediately remove the battery, wipe it gently with a dry cloth and put it in a plastic bag or a bowl with raw rice (as rice drains the moisture from battery). Place it on top of a shelf or somewhere safe for minimum 12 hours. Take out the battery from the plastic bag and clean it with dry cloth, then insert back into the phone and power on normally.

Yes, if the battery is not irreversibly broken (bulged, visibly damaged, etc.), those steps should be able to help.

Yes, you need to use a 9 volt battery to revive a cell phone battery or you can use freezing method; it takes time but it is more effective.

Your battery is dysfunctional. Replace it with a new one. They are inexpensive.

Not, it won't explode. But it won't be healthier for doing this, either. The ideal temperature for storing Li-Ion batteries is between 0 and 35 degrees Celsius. If you're wanting to hide your phone in the freezer, be aware that this might damage some circuitry and any moisture present can harm both the battery and the phone.
