How to Choose a Replacement Battery for Your Cell Phone

 Many people around the world own cell phones and use them as a convenient means of communication. Talking and texting are only two of the
 many uses for a cell phone: they can also take photos, browse the Internet, download data, provide a mobile hotspot, assist users with navigation, 
and supply a list of important contact emails, phone numbers, and addresses. Depending on their capabilities, cell phones may enable users 
to video chat, play games, watch movies or television, listen to music, set an alarm, calculate figures, and record important dates and appointments. 
In order to perform all of these tasks, a cell phone requires a battery that needs to be recharged periodically to keep the phone adequately powered. 
Certain media-intensive activities such as watching a television episode or streaming music will drain the battery faster than a simple phone call 
of the same duration can. 

 Eventually, the battery will wear out and will no longer be able to maintain a sufficient charge for everyday functions. At this point, users will need to 
purchase a brand-new phone or find a replacement battery. This guide offers practical tips for users who prefer to replace their phone’s battery rather 
than investing in an entirely new phone.
 

Signs That a Cell Phone Battery Needs Replacing
The signs of a failing cell phone battery are unmistakable. Generally, the primary indicator is a shortening battery life span. When the phone was new, 
owners may have been able use the phone normally for a few days without needing to charge it. However, when the battery is in the process of failing, 
it lacks the ability to hold a charge and may be drained after only a few hours. Sometimes a sporadic or faulty signal or other minor quirks can be attributed 
to a failing battery. One test for a failing or dying battery consists of removing the battery from the phone and placing it on a flat surface. A healthy battery should 
lie flat, whereas a failing battery will wobble slightly due to slight swelling. If the battery is unstable, users should take action immediately, since the battery 
could explode inside the phone and cause damage to the phone.

A simple way to remedy this situation is to purchase a new phone. However, if the phone is an expensive model with a variety of valuable features, or if the user 
simply enjoys their current phone and wants to keep it, a replacement battery may be a good option. Replacement batteries can be significantly cheaper than 
buying a new phone. However there are several factors to consider when selecting a replacement battery.

Warranty on the Battery
First, users should check to see if their cell phone’s battery is under any kind of manufacturer warranty. Usually companies will guarantee a cell phone battery for 
at least one year, though some phones may have a longer period of coverage for the battery. If the battery degrades completely within that time frame, the manufacturer 
should supply a replacement free of charge.

Even if users do not believe that their battery is still under warranty, they should call the cell phone manufacturer to ask if the company will pay for a new battery. If they 
say yes, users will have saved themselves some money. If they say no, users should inquire about the use of replacement batteries from third parties, to ensure that 
such a move will not compromise the warranty on the phone itself.

Battery Details
If the battery is no longer under warranty and the manufacturer refuses to fund a replacement, users will have to purchase the new battery at their own expense. They 
should ensure that they know the make and model of their phone, as well as the type of battery that will work in it. The model number is especially important. Specific 
details about the phone, such as its original name (the one assigned by the manufacturer, not the carrier) or any additional facts about the battery, can all be found in
 the cell phone’s user manual.

Users may also wish to pop the battery out of the phone and check the white sticker located underneath it. The sticker usually will contain the battery’s serial number, 
type, and IMEI number. This extra information will likely be useful during the purchasing process, since it enables users to make doubly sure that a particular 
replacement battery is compatible with their phone.

Another way of identifying the right type of replacement battery is to simply ask the manufacturer. The manufacturer may post such information online for easy access
by its customers. If not, a quick phone call its customer service department should yield the necessary details.
