I bought my LG G3 mid Sept. 2015. I am beginning to have troubles with it. Today is the third time it won't charge, or is super slow to charge. I have been using the adaptor and cord that came with it. I have tried restarting and also removing the battery, but it still won't budge. I don't leave it plugged in overnight (often) (My son gave me crap for doing that, so I don't unless I need to). I am a bit anxious since I will be travelling in the next couple of weeks and kinda need my phone to behave. Any suggestions?

It's been at least several years since you shouldn't leave phones to charge overnight. Any phone made in the last several years will stop charging the battery at 100%. I would let him know that and don't worry about leaving it to charge overnight.

It's possible that the battery or charger are giving you issues. First try another charger that you know works, and may as well try another device on the same charger you use. The next step if a charger that charges something else quickly but not your phone I'd say is a new battery.
There was a day I used three different chargers and none of them budged the number. Then after I restarted the phone, it worked. Another day I used the same charger, but took the battery out and back in and it worked. Now today I restarted it three times, took the battery out three times, and used a different charger (still LG). This last time I pulled the battery out, let it sit for probably 10 minutes, then plugged it back in, and now I see the numbers are up 10% already in 20 minutes. Good grief! 

So you think it might be the battery itself? Are those under warranty with the phone? My phone is less than a year old...

When a battery shows signs of slow charging or an inability to maintain a charge, the battery is usually suspect. Plugging the phone into chargers other than the OEM supplied charger, such as rapid chargers or in-vehicle chargers that have higher amperage ratings, can shorten the life of the battery.

Unfortunately, under Koodo's warranty repair policy, it doesn't explicitly state that they will replace the battery. They do however have to abide by the manufacturers one year warranty and LG does mention on page 129 of the users manual that: "During the applicable warranty period, LG will repair or replace at LG’s sole option, without charge to the original end user, any defective
component part of the phone or accessory".


The battery is considered an accessory. To save your self a little time, follow Bob's suggestion below regarding battery replacement.

Have you tried a different outlet or charger and charging cable?

Have you tried to charge another phone with this outlt, charger, and cable?
Yes, yes, and yes

Download a battery tester/monitor from the Google PlayStore. Give the phone a workout. If it's the battery, you will know quickly.

Back up your data and do a factory reset if the battery tests OK.


The battery is covered by warranty, but that will soon run out. Even if that's expired (or you don't want to surrender the phone for repair just before leaving on a trip), replacements are not that expensive.
