    I've had my U12+ since August 2018 (been a constant HTC owner since the Desire HD in 2010) and over the past few weeks I've noticed a strange chemical-type smell coming out the top around where the microphone is. It smells kind of like a Sharpie or permanent marker and is most noticable when the phone is on but is also there when it's charging. I charge my phone overnight by the bed and have been waking up with a headache because of it. I hadn't noticed anything at all until maybe two weeks ago, but it seems to be getting worse. The phone has never been dropped or damaged, and I like to think I take good care of my tech. Has anyone else experienced this?

    Welcome to Android Central! Do you have a case or screen protector on?

    I would contact HTC , and wouldn't charge overnight anymore just in case it's the battery giving off that smell.

    Welcome to Android Central.

    I have a U12+, but haven't noticed any odd smells. To be fair though, I don't use it as my daily driver, and haven't powered it on in a few days. Tomorrow I'll power it up, and keep an eye on it for a few days to see if I notice anything. I'll report back if I notice the same as you.

    As @mustang7757 suggested, I'd contact HTC, and keep an eye out while charging just in case.

    Have you had any other issues? Did you contact HTC? I pulled my U12+ out and haven't noticed the chemical smell. Also I forgot how much I like the size/weight ratio of this phone.

    Thanks for the replies. I haven't contacted HTC about it yet - that's probably a good idea. I've noticed sometimes I have to wait a few seconds after pressing the power button for the phone to wake up which I never used to, but that only happens rarely. It is a recent thing though. It's possible the battery is draining quicker lately as well, but that might just be my usage too. I haven't had any other issues, except with the touchy volume buttons at times (has a tendency for the volume to turn itself right up when I'm holding the phone, but aren't touching the button), which I believe is a known issue and has been like that ever since I first got the phone. I don't use a case or screen protector either. I'll keep you posted if I hear anything from HTC. What's the best way to contact them, through their website?

    I would contact them via their website. Also, it may be a good idea to always be in the room when you are charging your phone - but in case the battery is indeed giving off that smell, I would recommend not having your head near that odour.

    Please keep us posted!

    I got in contact with HTC through their website (did a live chat). They were very polite and asked for the IMEI number, a copy of the purchase reciept and some pictures of the phone. This is when I noticed some dark kind of leaking stuff through part of the transparent back cover. They advised me not to use the phone anymore because it might be dangerous. The warranty was not valid anymore as I bought the phone online and it wasn't a locally manufactured unit (I'm in Australia and apparently the phone was shipped from Hong Kong), was outside the 12 month warranty limit, etc, etc. They wanted to charge me an upfront $65 USD Global Warranty Service Fee (for shipping of parts for overseas variants) and a $49.50 AUD Diagnostic Fee (Assessment Fee and Freight charges back and forth) excluding the possible additional quotation for the parts that would need replacement (which would have cost who knows how much).

    Needless to say I've decided to ditch the HTC U12+ and I've gone out and bought a Samsung S10+, which I'm still getting used to but like a lot. Luckily I copied all my data from the U12+ last weekend, because just tonight I've noticed it's suffered a catastrophic failure. What I assume is the battery has expanded and delaminated the back cover completely off the phone in the top corner, across the top edge and down the side opposite the one with the buttons, and it doesn't turn on anymore. I watched the screen flicker and die.

    I still have no idea what caused this failure, but it definitely appears to be battery related. I've been using mobile phones since 1998 (exclusively HTC smartphones since 2010) and this is the first phone I've had destroy itself on me for unknown reasons. For a phone only about 15 months old it's pretty dissapointing.

    Anyway, the S10+ seems like a pretty good one - I only hope it lasts longer than the U12+ did!

    Yeesh, that's a lousy situation. You did all the right things, but it's unfortunate that it happened outside of the warranty period. Enjoy the S10+!

    That definitely sounds like the battery failed. I'd ask to buy the remains for parts, but if it had a catastrophic failure, then chemicals from the battery may have leaked into the electronics and ruined the internals.
