How to Replace a Mobile Phone Battery
With mobile phones being so ubiquitous and constantly in use, replacing parts to keep yourself connected becomes commonplace.
If you have not already experienced, or are currently experiencing a dying battery, you are or will be in the market for replacing your mobile phone's battery. There are many cellphone carriers and manufacturers, but the concept of replacing a mobile phone's battery is pretty consistent across the board. So regardless of what phone you may have, these steps will more than likely prove very useful for you on how to replace your cellphone battery.
For this tutorial I will be using pictures that show four different phones undergoing the removal of their battery. This is to illustrate the similarities, as well as the small differences between the phones.
The four phones used and how they are displayed in the pictures below:
LG Rumor Touch (upper left), LG CU500 (upper right), Kyocera Adreno S2400 (bottom left), and the Kyocera Loft (bottom right).
First things first, buy a new mobile phone battery
The first thing you need to do after determining you need a new mobile phone battery is to purchase one. There are several solutions to this.
- Take the phone to your carrier to get a replacement
- Use your user manual to contact the manufacturer or go to their website to order direct
- Search online for replacement (e.g. look up replacement battery for LG Rumor Touch)
- If nothing is coming up or there are multiple batteries on a search, follow the steps below to access your battery and use the serial number to search specifically for what you need.
Typically you can find better deals searching the internet, but be wary, a cheap knockoff battery could result in you replacing your battery sooner. It is always best to replace electronic batteries with the manufacturers battery.
Step 1: Powering down your mobile phone
First and foremost is to shut off your mobile phone. Each phone will have a feature for shutting down, such as a dedicated power button, or holding the hang up button. Whatever it may be, shut down your phone before opening it up.
Why should you power down your phone? This repercussions are debatable and will vary from phone to phone. However, this is just a cautious maneuver as some people have reported loss of data and problems with their settings. Then again, taking your battery out while the phone is live is also what is termed a soft reset, and is advised for problems that arise, like a frozen screen. I would play it safe and power down.
Step 2: Removing your cellphone battery cover
The next step is to turn your phone over and locate either a small arrow, or a tab that can be pressed to release the back casing of the phone. Some phones may not have any indication of how to open. These types of phones may have screws holding the back plate in place (such is the case for some Nokia phones), or you may simply need to press down and slide the back plating.
The best course of action if you are unsure is to consult your phone's user manual or visit the manufacturer's website.

Step 3: Removing the battery from your cellphone
Now that the case is off we have access to the battery. In the case of the LG CU500, the back panel IS the battery, so two steps in one! What a deal!
For the rest of the phones I am using in the demonstration, I am looking for a small groove or notch that creates space between the battery and the frame of the phone. This small space will allow me to use my fingernail, or a small object, to pry the battery out.
This method will alleviate the need to slap the phone in the palm of your hand in hopes of the battery popping out, which for me typically ends with the battery flying out of my hands and onto the floor.
Step 4 (Optional): Cleaning cellphone battery terminals
This step is optional, depending on the condition of your battery terminals.
Sometimes the battery terminals will appear dirty or corroded. If this is the case, get a cotton swab (a Q-tip works best) and some rubbing alcohol. Wet the cotton swab with the rubbing alcohol and wipe the terminals clean. This will ensure good contact and prolong your battery's life.
You can also do this as preventative maintenance, cleaning the terminals periodically on both the battery and the connecting terminals on the inside of the phone.
Recycle your mobile phone battery!
Don't just toss your mobile phone's battery in the rubbish! Check to see how to recycle batteries in your area, or you can go online and find programs like this:
Step 5: Replace the battery on your cellphone
This step is pretty much reversing everything you just completed. You should already have your cellphone's new battery, or at least now have a serial number you can obtain from the existing battery to help you order the correct part. Once you have the battery in your possession, follow these steps in reverse order to get you to the point of using your cellphone again.
Step 6: Charging a new cellphone battery
You have the battery in and everything is back in place, you fire up your phone and we have power! Though you may have minimal battery life, you do have power.
Do not go rushing to plug in your phone. Instead, check your user manual to see what the manufacturer suggests.
Some say allow the new battery to completely die and then charge it. Do this again a few more times before you start charging with the battery not all the way drained. Doing this may prolong the life of your battery and give you and your phone a longer lasting relationship.
