Why I Had to Replace My S21 Ultra Battery

As a proud owner of the Samsung S21 Ultra, I was initially blown away by its impressive features and performance. However, after a few months of use, I noticed a significant decline in the battery life. What used to last me a full day with heavy usage, now barely made it through half the day. This is when I realized that a battery replacement was necessary.

Firstly, with daily use, the battery’s capacity gradually decreases over time. This is a common issue for all devices and is known as “battery degradation.” As much as we try to prolong our phone’s battery life by charging only when needed or avoiding overcharging, it is inevitable that the battery will eventually lose its ability to hold a charge.

Secondly, constant use of power-intensive features such as high-resolution display, multiple apps running in the background, and 5G connectivity can also contribute to draining the battery faster. With the S21 Ultra’s top-of-the-line specs and advanced features, it is no surprise that the battery takes a hit.

Lastly, wear and tear can also affect the battery’s performance. Dropping your phone or exposing it to extreme temperatures can cause damage to the internal components of

After going through the process, I realized that it can be quite overwhelming to find the right replacement battery for your phone. So, I have put together this buying guide to help you make an informed decision.

1. Check the Model Number

The first step in buying a replacement battery for your S21 Ultra is to check the model number of your phone. You can find this information on the back of your phone or in the settings menu. It is important to make sure that you are purchasing a battery specifically designed for the S21 Ultra model.

2. Look for OEM Batteries

OEM (Original Equipment Manufacturer) batteries are made by the same company that manufactured your phone. These batteries are specifically designed and tested for your device, ensuring compatibility and performance. Although they may be slightly more expensive, it is always recommended to go for OEM batteries.

3. Consider Capacity and Voltage

When looking for a replacement battery, make sure to check its capacity and voltage. The capacity determines how long your battery will last while using your phone, while voltage affects how fast your phone charges. The original battery of S21 Ultra has a capacity of 5000mAh and a voltage of 11.55V, so try to find a replacement with similar specifications.

4. Read Reviews and Ratings

Before making a purchase, take some time to read reviews and ratings of different replacement batteries available online or in stores. This will give you an idea about the quality and performance of the battery from other users who have already used it.

5. Warranty

A good quality replacement battery should come with a warranty period, usually ranging from 6 months to 1 year. This ensures that if you face any issues with the battery within the warranty period, you can get it replaced or repaired without any additional cost.

6. Price Comparison

Last but not least, compare prices from different retailers before making a purchase. You may find different prices for the same battery at different stores or online platforms. Make sure to consider all factors such as shipping fees and warranty when comparing prices.

Taking Care of Your New Battery

Once you have purchased a new replacement battery for your S21 Ultra, here are some tips to keep it in good condition:

  • Avoid overcharging your phone as it can damage the battery’s lifespan.
  • Avoid using non-compatible chargers as they can cause damage to both your phone and battery.
  • If possible, try not to let your phone’s battery drain completely before charging it again.
  • If you notice any issues with the new battery such as overheating or quick draining, contact customer support immediately.
