Help Wireless charging question

[12345Michael54]

If it matters, this is with regard to an LG G3 phone, and a no-name Qi charging mat such as the one at http://www.ebay.com/itm/QI-Wireless...hash=item2eedc47a28:m:m5MivOnLIqxWKChk8uBy-Mg

Can I leave a Qi charging mat plugged in 24/7?

I'm thinking that if it's okay to do so, I'd leave it plugged in all the time, with the mat over on the corner of my desk, and just place my G3 on it whenever I'm working (at my desk) and not using the phone.

Any problems/dangers to doing this? Will it "burn out" the charging mat? Dramatically shorten the lifespan of my phone's battery? Cost me a fortune in electricity?

While I've never used a wireless charger before, and my knowledge of electricity is nothing to write home about, I suspect it'd be perfectly okay. But I figured it wouldn't hurt to post the question and get confirmation.

Yes I've got a couple here that are plugged in all the time. They just sit there doing nothing until a phone with a Qi charging coil is placed on them.

I always left my charging mat plugged in with no problems. I would consult the manufacturer of your mat to be certain you are ok. It's way handy to put a quick charge on a phone or over night charge with the mat plugged in. Not so hand if you have to plug it in prior to each use. My feeling was if there was danger or excessive expense of the mat plugged in while not charging a device it would have an on off switch in place.

yup,

I have 3 of them scattered around the house.

And, that is the whole purpose of a Qi Wireless Charging pad.

the pad stays plugged in all the time...
you just lay the phone on it and it starts charging.

Just in case you needed another affirmation,it's OK to leave plugged in/idle 24-7.
For some contrast,mine go through feast or famine use,depending upon my use of phones with QI Charging capabilities.
Currently,I have only one such device & it's not a daily driver,so,my 3 chargers have been plugged-in for several weeks w/o use & I still have a roof over my head......

And, same here.

Your phone's charging circuitry will charge to about 90%~95% full and with Qi it can get a little warm (it's an induction coil, after all -- the same technology used in glass top electric stoves) but nothing it can't handle. After that it will trickle charge to 100% and then shut off charging. If you leave it there as the battery level drops it will resume a trickle charge at ~95% and take it back up to 100% with very little heat generated. Modern LiIon batteries perform better on smaller incremental charges than a full charge/discharge cycle.
