Why Replacing iPhone is Important

Replacing your iPhone battery on time is essential to ensure that your device functions properly. A failing battery can lead to a range of problems, such as:

  • Extremely fast battery discharge
  • The device only turns on when connected to the charger
  • The appliance switches off at low temperatures
  • The smartphone works slowly when the charging rate is low.

Removing "Important battery message" pop-ups on iPhone XS to 15 Pro Max

Apple has encrypted the battery on the iPhone XS and later models. When you replace the battery, you get the message "Important battery message" and "Service". Especially the battery data of the iPhone 11 and 15 series cannot be accessed even after installing an aftermarket or original Apple battery.

To solve this problem, we introduce the structure of the battery. It roughly consists of two parts: the BMS board and the battery cell. The BMS board serves mainly as a protection board but also stores battery data. The iPhone XS, as an example, requires a battery data corrector and a new battery cell. After this, you need to disassemble the phone, remove the battery, and weld the BMS board from the original battery to the new battery cell.

It is essential to remove the original BMS board and solder it properly. After soldering, you need to install the BMS board and apply protective tape. Since the BMS board has been replaced and the battery protected, the voltage cannot be measured. It is necessary to activate the battery with a DC power supply.

Importantly, you can only switch on the phone with a power cable. After this, you can install the new battery and go to "Settings" to view the battery health information.

There are also additional steps for the iPhone 11 series, such as installing the BMS board, activating the battery with a DC power supply and using a specialised PCB board to read the data.

At FixNow we carry out these procedures carefully, using the latest technologies and expert technicians to ensure your iPhone performs optimally after battery replacement.

Apple battery replacement

The quality of products made under the world-famous Apple brand is not questioned or claimed by anyone. And yet, it happens that the "Apple" devices need repair or replacement.

Despite the high quality of components used by Apple, battery replacement may become necessary over time, if the user does not follow the usage instructions or if the capacity decreases. Both low and high temperatures have a negative effect. For example, if the iPhone is in direct sunlight in summer or has been left out in the cold, the battery may lose capacity and last less long.

The quality of non-original chargers can also damage your iPhone's battery quite quickly. Therefore, one of the important rules is not to buy third-party battery chargers.

What are the signs that the battery needs to be replaced?

Apple iPhone battery uselessness can be expressed by a number of signs.

These may include the following:

  • The battery begins to discharge extremely quickly;
  • The device turns on only when charger is connected;
  • The unit switches off when the temperature is low;
  • The smartphone is slow when the charging rate is low;
  • When you make a call, the iPhone suddenly cuts out.

These problems may indicate the need to replace the battery, which has failed due to normal wear and tear, moisture entering the device or exposure to high (low) temperatures. In addition, the battery may need to be replaced in cases such as:

  • The iPhone's screen is bulging and there are spots on the screen (the problem is usually caused by a "blown" battery, which presses on the screen from inside and distorts it). In this case, the battery urgently needs to be replaced;
  • The battery percentage fluctuates continuously and the device spontaneously reboots;

How to Extend Battery Life

It is possible to extend the life of your iPhone battery by taking some simple precautions:

  1. Avoid extreme temperatures: Do not leave your iPhone in environments with temperatures below freezing or above 35 degrees Celsius.
  2. Avoid exposure to direct sunlight.
  3. Do not discharge your smartphone under 10%.
  4. Close all applications not currently in use to save battery power.
  5. Only use the original accessories that came with your iPhone, such as the USB Lightning cable and power adapter.
  6. Avoid using portable Power Banks and car chargers.
