Even years after its release in 2014, the OnePlus One is a popular smartphone. However its built-in batteries will probably have worn out after all these years of usage.

Although the built-in batteries were not intentionally designed to be replaced by end-users, this is still possible. Replacement batteries are available through online shops. Some of them even maintain the original design of the OnePlus One batteries.

The batteries are connected to the motherboard via a ribbon that needs to be carefully disconnected first. To this end, you open the smartphone and unmount the motherboard cover. The batteries themselves are not packed in a hard cover. Hence, extra care is required when removing them.

This guide will walk you step by step through the process of removing the batteries and give useful advices on the mentioned dfficulties. After you will have removed the battery, you can just plug in your own by executing the steps in reversed order.

  1. Remove the SIM tray.
    • Remove the SIM tray.

    • Using a plastic opening tool, carefully separate the back panel from the main body assembly of the phone. Be extra careful around the SIM slot or other weak areas.

    • You may encounter some resistance due to hidden locking clips around the inside edge of the phone. Not to worry; just move in one consistent direction around the phone as opposed to jumping from spot to spot!

    • Top to bottom, left to right, clockwise or counter clockwise, once we make it about half way around the device, the panel is easily removable by hand.

    • It is of utmost importance that you do not attempt to free the battery from the device at this point without proceeding to the following step! This is an integrated battery that can easily be damaged or destroyed if the proper steps are are not taken.

  2. Using a pair of tweezers, remove the plastic plugs.
    • Using a pair of tweezers, remove the plastic plugs.

      • Once the hidden screws are revealed, use a PH #00 screwdriver to remove the three 3.175mm screws.

    • Use the PH #00 screwdriver to remove the remaining six 3.175 screws.

    • Using a plastic opening tool, gently pry up the black plastic cover and remove it from the device.

    • After we have removed the motherboard cover, we notice that the battery is intact and has a black ribbon attached to it, which is mounted on the logic board.

    • Using the spudger, carefully begin to lift the the battery up from the side opposite the ribbon. Be aware that there is high-grade adhesive holding the battery in its bay, so proceed with caution.

    • This battery is not encased in a hard shell so it is soft and malleable. Caution must be taken during removal so as not to cause permanent damage.

    • Once the battery has been freed, we use the ever handy black spudger to pry up and free the battery ribbon from its dock.

    • You can disconnect the battery before freeing it to make removal easier.


To reassemble your device, follow these instructions in reverse order.

The Apple iPhone sim ejector is not long enough to work on an OPO. A paper clip is a better option.

There will be a compatible battery with one pin OnePlus

Successfully accomplished, thanks to your clear instructions. One note: the adhesive on my unit was applied in about a quarter inch strip along the right underside of the battery as you view it from the back. Peeling up the left side allowed me to reach and release the adhesive on the opposite side with the spudger or knife blade.

Thank you! I use a slim (but not sharp) butter knife to nudge the battery out slowly by poking the adhesive tape along its length. It was a bit unnerving because I was afraid of damaging the soft battery. Worked out in the end.

One note to add is that the original battery connector's top was glued to the motherboard cover. I had to remove the battery before I could successfully sepearte the 2. My phone is still working and I'm charging it right now! :)

Thanks for the very detailed guide.
