Introduction

The OnePlus One is an excellent smartphone but as all smartphones come, their batteries will eventually wear out and will need replacement.

Image 1/3: 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. Image 2/3: 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!

  • Remove the SIM tray.

  • 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.

It doesn't mention you have to remove SIM tray first.

I used the #0 for the rear panel screws. The #00 is too small and will slip, stripping the screws if you're not extra careful.

where can i buy the battery??

Has anyone answered this? I am looking too.

Elie Daou -

They sell it on here, although I found mine on eBay.

Aliexpress for $9 (original)

The last three hidden screws are a !&&* of a time consumer to remove. probably you would need only a certain type of tweezers - I got stuck at midway and now I cannot get go have my phone detect the sim card either probably because the six screws are removed. I can now turn the phone back on but with no service or wifi connections are detected. This phone is a disaster!

Manan Shah - Reply

Ivdid that too but son in law found I had reinstalled sim card in backwards or upside down.

Davide Rota - Reply

EBay. I bought new battery cause old ibe was dead would not charge. Just ordered new cables fit 9.00 something free shipping. Anyway hope this fixes problem cause new battery did not fix problems.

I was able to open going from the microusb slot and working my way around. The corners are tough, though.

in my phone the battery was glued with double sided adhesive tape, only on the right side. I pried the left side up first, and carefully removed the battery. to lift the battery I used first used a suction cup(?) followed by a plectrum like tool to lift te battery, and keep it lifted

A word of caution: the back panel is harder to remove than you might think. Especially because you may be removing the *screen* by mistake. When you have a "grip" with the tool make sure the metallic border is not coming off with it, and when you have removed enough to be able to lift the panel, make sure it isn't attached by ribbons - in that case you've been removing the screen. A good idea is to gently press your finger nail against the weak plastic located between the back and the SIM slot, and going up and down and sideways until you hear a click. Then you can start from there with the opening tool. As recommended be very gentle around the SIM slot.

Image 1/3: Keep in mind that there are four hidden screws. One underneath the white tamper sticker(uh-oh) and a second under the plastic plug(circled in red), and 2 more under plastic plugs to the left and right of the camera. Tweezers are an effective tool for removing the plug. Image 2/3: Luckily, the OnePlus One was assembled with all of the same size screws save for the  one holding down the motherboard. All of ''these'' screws are Philips 00 and 3.175 mm. in length. Image 3/3: Once all of the 9 screws have been removed, you can pry the cover off with  the blue opening tool, exposing the motherboard.
  • Using our #00 screwdriver, we remove the screws around the outer edge of the upper interior cover of the phone that houses the motherboard and cameras. See info note below!

The plugs are annoying to open for the first time. They're shaped like little pegs, but I was able to poke at them with screwdrivers enough to open.

Roger - Reply

the best spot to start prying the cover open is at the cable outlet for the power/volume buttons (careful not to dameage the wires)

Dangerous Pictures - Reply

A needle works best to remove the plugs.

Stan Barton - Reply

I second this. I used a sewing pin and the plugs came out in no time!

Be careful not to displace the rear camera when replacing the motherboard cover.

Image 1/2: 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 caution and patience are your friends.

  • 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.

This took a ton of force to remove from the adhesive!

Also I was able to take off the cable before removing the battery.

Roger - Reply

Is it OK to use the battery if I bent it during removal? I had to 'iron' it flat, but I think it might still be useable...

Henry Annand - Reply

the best way to remove the battery is to lever the left side up from the bottom and remove it from the glue with an old credit card

Dangerous Pictures - Reply

Do this! it comes up very easily this way. All the adhesive is on the right side.

Daniel ONeill -

Great suggestion with a card to remove the battery!

Jeff Mack -

I second Dangerous Picture's suggestion. I found it very helpful to remove the ribbon from the dock (it was easy to do) before trying to remove the battery.

Stan Barton - Reply

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

For step 4, the connection to the battery should always be done as soon as possible so after removing the back plate to the board would be ideal.

Otherwise, very thorough so far!

Thought I was going to snap my battery in half but patience and slight pressure did the trick.

Also agreeing the battery should be disconnected as soon as possible.

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.

That Guy - Reply

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.

Benoit Hogue -

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.

Benoit Hogue -

Works great!

How can I tell if the charging port or the battery that is damaged?

Ang Wei Ming - Reply

After doing this my screen no longer works. It's just a black screen whether I use the old battery or the replacement.

Terry Atkinson - Reply

Fixed the black screen issue by taking the cover off and then checking all connections and putting back together. All good now. Hardest part was to get the cover off. Starting from the sim card port worked eventually.

After the grand success of OnePlus 3 and OnePlus 3T (the upgraded version of OnePlus 3), the makers are planning to launch the 4th generation of the series, the OnePlus 4 with even better features and specs. It would give tough competition to iPhones

when it releases because of the extraordinary features it would have. To know more about OnePlus 4, its http://www.oneplus4update.com/ just take a look here.

anyone knows where can i buy a good quality battery? i dont want a cheap replacement...

Moti Dorfman - Reply

I just got mine from this Ebay seller: http://www.ebay.com/itm/162062594869. It is an original battery, as far as I can tell.

Ordered it on Monday, received it on Friday. It took me about 30 minutes to replace the battery and it seems to work.

I just very proudly followed these instructions and my phone switches on again \o/

Now the touchscreen is unresponsive :-( what did I do wrong?!

Also- is the old, broken battery hazardous? What should i do with it?

Dud - Reply

Burning. Flushing down the toilet is also a popular choice.

I am looking for the new battery to replace old one in my Oneplus one. Can anyone help me, where can I get the genuine one or at-least a good one?

me_paracom007 - Reply

Good manual! Be careful the battery cable is attached to motherboard cover. Don't tear it off right away. Loosen the motherboard cover and SLOWLY and CAREFULLY lift it to see whether yours is attached too. Also get 1-2 plastic cards like credit cards to lift the battery from the tray. Mine was glued on the right side if you look at the battery with phone lying on the table face down. Make sure to discharge your battery before removal.

My phone only comes on when it's plugged to power. Could this be a battery problem? How can I get a new battery in Nigeria?
