What should I do with my slightly puffed phone battery?

I've been using an old phone that's over ten years old, and lately, I've noticed that the back of the device is slightly puffed out. The phone has had several battery and screen replacements and has struggled with battery life for some time. I'm in a pinch and have to keep using it for about a month. Are there any tips on what I should do with this puffed battery? Can I still charge and use it safely?

If you have to keep using it, store it on something like a baking sheet to catch any potential fire damage. But really, see if you can afford to get the battery replaced; it's often much cheaper than replacing the whole phone.

I had a similar situation with my iPhone. I used it with a puffy battery for a while, but I only charged it while I was nearby, just in case. It worked for weeks, but I wouldnโ€™t recommend it at allโ€”itโ€™s a bad idea.

Don't charge it or use it anymore. Puffing indicates that the battery is faulty and could potentially explode or cause a fire. Itโ€™s better to be safe than sorry! If you can, replace the battery sooner rather than later.

It's really concerning that your battery is puffed. Honestly, you should avoid using it at all. I understand you need it for a month, but a failing battery can be dangerous. Back up your important data onto your computer or a USB drive right away. Then, consider replacing the battery or getting a new phone, as using a puffed battery isnโ€™t worth the risk.
