The Complete Cell Phone Battery Guide

A cell phone battery that doesn’t hold its charge can be a frustrating experience. You’ll always need to have a charger close by to keep it from dying. You can prevent this by knowing more about how cell phone batteries work and how to maintain them. We’ll cover a lot of information about cell phone and smartphone batteries that can help you make better buying choices and handle your phone more efficiently.

Whether you’re looking to improve cell phone battery life or to learn more about smartphone batteries, you’ve come to the right place. This article covers the major cell phone battery types, how to prevent your phone battery from dying and how to replace a cell phone battery.

Cell Phone Battery Types and How to Tell What Kind You Have

To understand the needs of your battery, you need to know what kind of battery you’re using. Generally, there are four different types of batteries used in cell phones:

  • Nickel Cadmium (NiCd): This type of battery is generally only used in older cell phones and is the least powerful.
  • Nickel Metal Hybride (NiMH): These nickel batteries are more powerful than the NiCd batteries. They are usually only used in older cell phones, as well.
  • Lithium Ion (Li-ion): This a more common type of battery, as it’s consistently used in today’s phones. It’s even more powerful than the NiMH.
  • Lithium Polymer (LiPo): Like the NiHM’s upgrade over the NiCD, the LiPo is an upgraded form of lithium battery when compared to the Li-ion, as it comes with greater power.

As NiCds and NiMH batteries are out-of-date, it’s likely that you aren’t using one in your cell phone anymore. Unless you’re using a very old model, your phone has a LiPo or Li-ion battery.

To figure out whether you’re using LiPo or Li-ion batteries, you can often simply look at the label on the battery itself. If you can’t find the label or if it has been removed, you can find the info in the user manual.

After you’ve figured out which battery you have, you’ll have a better idea of what effect it will have on your device.

Li-Ion Batteries vs. LiPo Batteries

Li-ion batteries vs li-po batteries

Li-ion batteries and LiPo batteries are the two main battery types on the market today. Li-ion batteries are the most popular type of cell phone batteries among cellphone manufacturers, while LiPo batteries are the most advanced cell phone batteries available to consumers.

1. Li-Ion Batteries

Of the two top types of cell phone batteries, the Li-ion battery has been around the longest, with it being the first to be used in smartphones. Chemically, they are made up of a positive electrode, a negative electrode, and an electrolyte. The positive electrode is a lithium compound such as lithium manganese oxide, lithium iron phosphate or lithium cobalt oxide. The negative electrode is usually graphite, and the electrolyte is a carbonate, such as diethyl carbonate or ethylene carbonate.

There is an organic solvent between the two electrodes where the electrolyte is stored. To keep the battery in one piece, a metal case holds it together tightly. As a safety precaution, these batteries also feature a protection circuit that regulates the battery levels and voltage within safe limits.

Li-ion batteries provide high energy density. Additionally, these batteries have a long-lasting shelf life and are easily switched out, making them user-replaceable.

Though the batteries have many benefits, they do come with disadvantages. They generally have a higher weight, making the phone heavier. The phone’s protection circuit often increases the costs of the battery as well. Compared to LiPo batteries, Li-ion batteries have a high self-discharge level. Additionally, they are usually available in a rectangular shape, which can be problematic for uniquely designed phones.

2. LiPo Batteries

LiPo batteries came after Li-ion batteries. They are very similar in terms of their components, but they do have a difference in their separator, which is the material between the electrodes where ions move. In a LiPo battery, the separator is a microporous polymer covered with an electrolytic gel.

The separator acts as a catalyst for the chemical process. Similar to Li-ion batteries, these batteries have a protection circuit to keep the voltage within a safe range. Unlike Li-ion batteries, they do not require a metal casing.

These batteries are growing in popularity for several reasons. For one, their self-discharge level is quite low, and their weight is significantly lower than Li-ion batteries. These batteries also can come in a variety of shapes.

Despite their benefits, the batteries do have some negatives to them. LiPo batteries have a lower energy density and can be more expensive. In comparison to the shelf life of Li-ion batteries, their shelf life is noticeably shorter. Users cannot replace these batteries.

How to Make Your Phone Battery Last Longer on a Single Charge

How to Make Your Phone Battery Last Longer on a Single Charge

If you’re wondering how to extend the life of your phone throughout the day, you can make several changes whether you have an iPhone or an Android. Below are some of the main options available to users:

1. Dim Your Screen

One of the simplest ways to keep your phone charged throughout the day is to dim your screen. Regardless of the type of phone you use, an overly bright screen will drain the battery and increase the operating temperature of your phone. By lowering the phone’s temperature, you extend your battery life and increase the phone’s life span.

2. Turn Off Location Services

A major drain on your phone is likely coming from your location services or GPS functions that your phone provides. This feature complements directional apps like Google Maps, but many other apps also use it, even if you don’t realize it. If you don’t need your phone to know your location, turn off location services, and reap the battery-saving benefits.

3. Cut Down on Your Use of the Vibrate Function

While many have probably had the vibrate function on their phone on since they first took it out of the box, it’s wise to put the phone on ring occasionally. While it might not be obvious, a ringtone takes up less battery than a vibration. So, when you don’t need to have your phone on vibrate, turn on your ring tone or simply set it to silent mode if you don’t need to hear it at all.

4. Say No to Push Notifications

While push notifications can be occasionally helpful, they often provide you distracting information you don’t need, while also harming your battery life throughout the day. Anytime your phone gets a push notification, it lights up, draining the battery. Some push notifications also come with a vibration or a ringtone, further affecting battery life. Get rid of most push notifications, if not all, if you want to keep your phone’s battery running strong.

5. Disable Most or All Background Data

Background data can be a hidden source of battery drain on your device. Apps will continuously run even if you don’t have them on, taking up your phone’s bandwidth. This kind of drain due to background data is especially impacted by social media and email apps on your phone. In your settings, you can turn off all background data, or you can choose only to have a few choice apps running in the background. Whatever you select, it’ll use less battery.

How to Make Your Phone Battery Live Longer

If you want to improve your cell phone battery life beyond keeping your daily battery use low, try these methods for increasing how long your phone’s battery will last in the long term. Here are some of the main tips to extend your battery life:

1. Reduce Battery Discharge

Lithium-ion batteries are meant to keep the same charge capacity for between 300 to 500 charge/discharge cycles. However, batteries typically fall to 80% of their battery capacity within only 100 charge/discharge cycles.

To make sure you get the most out of your battery, you want to limit how often the battery discharges completely. While some might think it’s best to let the battery get down to 0% before charging it again, any phone battery charging guide will tell you that waiting this long could actually harm the battery. Instead of waiting, always keep your phone partially charged, restoring it to 100% battery if it starts to get too low.

2. Avoid the Heat

Keeping your phone out of the heat is one of those long term actions you can take to make sure that the phone doesn’t overheat and become damaged. For example, direct sunlight can take phones over their 113 Fahrenheit limit. If the phone is regularly in these conditions, it will often degrade faster, reducing the amount of charge it can hold.

To protect your phone, keep it out of direct sunlight. This is especially important in the summer, as surface temperatures can easily reach 158 degrees. Leaving it in these conditions for an extended period will lead to your battery losing its charge capacity faster.

3. Don’t Let Apps Pile Up

Though it’s tempting to stockpile apps that you might use in the future, it’s better to keep your apps from piling up. Having many useful or fun apps on your phone may seem like a good idea, but, over the long run, your phone’s battery will thank you for being judicious in the apps you allow on your cell phone. Having multiple apps will add to your background data and increase your battery drain. An easy way to cut down on these types of apps is to eliminate apps that serve the same purpose. Do you need two weather apps? Three news apps? You can save your battery and your time by preventing your phone from repeatedly showing you the same notifications from different sources.

4. Don’t Fast Charge

While many phones will have fast charge options available now that let you charge your phone in a few minutes, you should avoid using them. The fast charge feature is okay if you’re genuinely in a rush, but don’t use it regularly.

The reason to use fast charge features sparingly comes down to the loss of storage capacity that occurs when a battery is charged. When lithium ions and lithium metals are shuttled between electrodes within lithium-ion batteries, they move slowly. When you charge at a slower rate, you let the shuttling process occur at its natural rate, fully completing their movements. By charging more slowly, you’ll increase the capacity of your battery’s charge.

Whether fast-charging or slow-charging, it’s also important to remember to unplug your phone when it reaches 100% as overcharging will damage your battery. Many newer chargers, like those that come with fast-charging phones, are built to be “smart” and automatically avoid overcharging your phone. However, you will see the best results for the life of your battery if you unplug your phone when charging is complete.

Phones With the Best Battery Life

Several options on the market today have superior battery life when compared to older phones and other popular phones on the market. When it comes to battery life, look at the milliamp-hour (mAh) of the phone. The higher the mAh, the longer the battery life and the higher the battery capacity.

  • Moto G7 Power: These cell phones come with a 5000mAh battery capacity. In testing, the phone ran for over 14 hours. If you want a long battery life, the Moto G7 Power is an excellent option.
  • Huawei Mate 20 Pro: This phone has 4200mAh along with energy-efficient software that helps the battery get close to 11.5 hours in a single charge. The Huawei Mate 20 Pro gives you the confidence that your phone will last throughout the day, even with constant use.
  • Huawei P30 Pro: Another Huawei model, it comes with a similar 4200mAh battery. Like the Mate 20 Pro, the P30 Pro lasts for about 11.5 hours.
  • Moto E5 Plus: Like the Moto G7 Power, the Moto E5 Plus prioritizes battery life and comes with a 5000mAh that has been tested to run for seven hours.
  • iPhone XR: The iPhone XR has the longest battery life of all iPhones. Compared to the iPhone 8 Plus, the iPhone XR will last 1.5 hours longer off one charge. The battery usually lasts for about a day and a half before needing to be recharged.

Phones With Removable or Replaceable Batteries

Phones with Removable and Replaceable batteries.

Phones with removable batteries might seem like a thing of the past, but some phones still include them. If you like to have multiple batteries so you can be sure you always have a charge, one of the following older phones might be perfect for you:

  • LG V20: The LG V20 comes with a removable battery, along with a headphone jack and 64GB storage. It also has a dual 16-megapixel rear-facing camera that has a 120-degree wide-angle lens. LG makes several models with removable batteries, including the LG V10 and LG G5.
  • Moto E4: The Moto E4 has 16GB or 128GB of storage. It also comes with camera tools, lightweight design and a water-repellant coating.
  • Samsung Galaxy S5: The Samsung Galaxy S5 is the last Samsung produced with a removable battery. Though it’s a little older, it comes with HDR camera mode, dust and water resistance and a heart rate monitor.

Many of these phones are no longer being manufactured, but there’s a good chance you can find one at brick and mortar retailers or online at The Whiz Cells eBay store.

How to Replace a Worn out Android or Apple iPhone Battery

If you don’t have a removable battery, your cell phone battery replacement is going to be more involved than simply turning off your phone, taking out an old battery and placing a new one in. As non-removable cell phone batteries are not meant to be removed by the user, it’s recommended to go with an authorized repair service center. If you do decide to do it yourself, there are a few tips to follow:

Android Battery Replacement

Android phones have unique features that play into their repair. So, you want to research the intricacies of your specific phone first. After researching the phone, follow these general tips if you’re set on repairing the phone yourself:

  • Turn the phone off before you begin the repair.
  • If you’re replacing a lithium battery, make sure it’s below 25% battery life. A charged battery can explode or catch on fire if punctured by accident.
  • If your battery is swollen, do not attempt a repair yourself. It may be more volatile and likely to harm you.

The basic tools you need include:

  • A flat opening tool
  • A heat gun to melt the adhesives
  • A screwdriver
  • Tweezers
  • A suction handle
  • Replacement adhesive to glue the phone back together

iPhone Battery Replacement

iPhone battery replacements are fairly inexpensive and are free with a warranty or AppleCare+. Due to the iPhone’s design, we recommend you send your phone in to be repaired rather than trying to do it yourself. You can find plenty of information on this process through Apple Support.
