How long should my Samsung Galaxy S4 Replacement Battery last?
Our extended battery is double the capacity of your original battery. So you will receive twice the battery life of a standard battery with the same amount of use. Please follow the proper initial charging and cycling instructions.
How to maximize my Galaxy S4 extended life battery potential?
To get the full extent of your new battery, please follow the conditioning cycles. When you first receive the battery be sure to charge it all the way up before using it. We recommend overnight. You will then need to discharge the battery and recharge fully again entirely. This process will allow your phone to adjust to the new battery capacity.
How long should I charge my new Samsung Galaxy S4 extended battery?
Depending on the size of your battery we recommend 9 to 10 hours of continuous charging. If your battery is 4500mah or higher, you would want to charge your battery for at least 10 hours.
Why is my Galaxy S4 battery not fully charged?
There could be many reasons your battery is not fully charging. The most common are not allowing the battery the full length needed to charge fully. Batteries 4500mah or higher would need to charge for 10Hr. If you can not fully charge your battery after 10+ hours, please contact us via email at firstname.lastname@example.org or by phone at 1-888-663-5998
My battery has a bulge in the middle. What does this mean?
There are a few reasons for this. If your battery is over a year old, it could mean your battery is seeing its last days. If you’ve only had it for several months, it could be due to improper charging. If you are still within warranty, please contact email@example.com
