Signs you need this repair

  • The battery drains much faster than it used to
  • It switches off with charge still showing
  • It only runs while plugged in
  • The percentage jumps up or down suddenly
  • It won't charge past a certain level
  • The back is bulging or the screen is lifting (stop using it and get in touch first)

Lithium batteries wear with use. Each charge cycle takes a little capacity away, and heat speeds that up. Eventually the battery can't hold enough charge for a decent session, or it can't deliver power steadily and the console shuts off early.

Swollen battery? Don't post it yet. A swollen or damaged lithium battery can't be sent through Royal Mail. If the back of your Switch 2 is bulging or the screen is lifting, stop using it, don't charge it, and get in touch before posting anything.

Warranty first. The Switch 2 is still a young console. If yours is under Nintendo's warranty and the battery is failing without any damage, go to Nintendo first. This service is for consoles out of warranty, or where you'd rather keep your own console than have it swapped.

What I do. The battery in the Switch 2 is glued in, so I open the console, release the adhesive carefully without bending or puncturing the old cell, and fit a replacement battery. Then I charge it, check it reports correctly, and run the console on battery before it goes back. If drain is the problem rather than a dead battery, it's worth checking your settings first, and if it won't charge at all, the charging port repair may be what you need.

Back up first. Your saves live on the console's soldered storage. A battery swap doesn't touch it, but back up with Save Data Cloud first where the game supports it. My save data guide shows how.

Frequently asked questions

How do I know it's the battery and not the charger?
If it charges fully but runs out quickly or shuts off early, that points to the battery. If it won't charge at all, try the official charger and another cable first, because that's more likely a charger, cable or port fault.
Is it worth replacing the battery on such a new console?
If it's under Nintendo's warranty and the battery has failed on its own, go to Nintendo. If it's out of warranty or the console has been damaged, a battery replacement is far cheaper than a new console.
Can I carry on using it while I wait to post it?
If the battery is just tired, yes. If the back is bulging or the screen is lifting, stop using it and don't charge it.

About this service

How does your mail-in repair service work?
Three steps: book and pay for your repair online, post your item to me using the packing instructions I email you, and I repair it, test it, and send it back tracked. You'll get updates as it moves through each stage.
What is your no-fix-no-fee promise?
Payment is taken upfront at booking. If I can't fix your item, there's no repair fee — I refund what you paid, less £4.99 return postage to send it back to you. Assessment bookings work differently: the £4.99 covers return postage and comes off the repair if you go ahead, but isn't refunded if you decide not to or it can't be repaired.
Do your repairs come with a warranty?
Yes. Every repair carries a 12-month workmanship warranty against the same fault returning. If it does, I'll put it right.
How long will my repair take?
Most repairs are completed within 3-6 working days of arrival, then posted back by tracked post. If a part needs ordering, I'll tell you as soon as I've diagnosed it and give you a realistic date. Diagnostic-led jobs take a little longer if I'm waiting on your approval of a quote.
How do I package my item safely to post it?
I send clear packing guidance when you book. In short: wrap the item well, use plenty of padding, and a sturdy box — the return leg is insured and tracked, and good packing on the way in protects your item too.
Where do I send my item?
Your postage address is included in the confirmation email after you book — you don't post anything until you've booked, so your item is always matched to your order.
Do you cover the whole UK?
Yes — I run a mail-in repair service, so you can send your item from anywhere in the UK. There's nothing local you need to find.
What if my item turns out to be unrepairable?
I'll tell you honestly and, where the fault allows, offer an alternative. If I can't fix it, there's no repair fee — I refund what you paid, less £4.99 return postage to send it back to you.
