If you purchase an prescribed case for yourOnePlus 13 , you ’ll find something unexpected in the box . It ’s a paring of flexible plastic , form like something you hang on a hotel room doorway when you do n’t require the maiden to fall in , and although your first instinct will be to flip it away with the rest of the packaging , do n’t do it .

You may finish up needing it .

What does it do?

The pliant celluloid serves a purpose if you bought one of the glass versions of the OnePlus 13 . According to the endorsement on the film itself , this is what it does :

“ For the good wireless charge experience , please direct the wireless charging covering fire between the back of the Arctic Dawn version of the OnePlus 13 and your sound type . ”

The OnePlus 13 has wireless charging , and all the prescribed OnePlus 13 cases have a ring of magnets inside to help locate the AirVOOC 50 - James Watt radio set charge puck for the best performance . While the fictile insert amount with all the shell , it only seems to be required with the Arctic Dawn earphone . I’vereviewed the Midnight Ocean OnePlus 13 , and wireless charging seems to work with and without the insert and at the same speed .

Don’t throw it away. But why?

The weird plastic filmdoesserve a purpose , and count on the color of your OnePlus 13 , it may be important . But what does it actually do , how does it work , and why is it only required for the Arctic Dawn speech sound ? We asked OnePlus for illumination and received this reply :

“ [ The ] OnePlus 13 is the first speech sound to feature a microfiber vegan leather color called Midnight Ocean , as well as two glass back colors called Arctic Dawn and Black Eclipse . As these stuff have unlike heaviness and compositions , we let in a plastic film in the typeface of our Arctic Dawn and Black Eclipse models to ensure efficient and efficient wireless charging . ”

This does n’t really give us much brainstorm into how it works , but it does indicate the picture mayalsobe take if you own the Black Eclipse phone , despite it not being stated on the film itself . The safe solvent is if you require to expend wireless charging , it ’ll be saucy to just put it inside the case anyway , disregarding of which methamphetamine hydrochloride OnePlus 13 you buy .

Care is needed

Now we know why you necessitate to place it in the casing . Is it as simple as it voice ? Yes and no . It ’s not a pretty point , and it ’s the first time I ’ve encountered the motive to put something from the manufacturing business between my case and phone to improve functionality . When you place the photographic film inside the slip , it ’s hard to get it rivet aright , and it will in all probability cling out of the camera opening once it ’s sandwich between the telephone set and the case .

Instead , the honorable matter to do is place it on the back of your OnePlus 13 first , concur the phone flat with the back facing toward you , and then put the typeface on your telephone set . This keeps the film from shifting around . Once it ’s inside the sheath , it ca n’t be seen , does n’t tote up any weight unit , and will stay in post until you take the case off . It ’s for certain not the most elegant resolution to a problem of OnePlus ’ own qualification , but at least it come up with a answer rather than just discount it and permit phone proprietor plow with unexpected slow wireless charging .

However , it seems unlikely third - party typesetter’s case manufacturer will fabricate and include the required flick with their cases , particularly as it ’s only necessary for two version of the OnePlus 13 , so anyone who does n’t grease one’s palms a case from OnePlus may end up encountering issues .

If you ripped open your OnePlus 13 fount loge and throw everything aside to get to the case itself , now you know what the strange piece of plastic you believably discarded does — and why you may want to make certain it gets used rather than send off for recycling .
