How to fix LG G3 slow charging issue

Make sure you are using the original charger

When you are about to charge your LG G3, make sure that you are using the charger that came with your device.

Try a different charger

If the problem occurs when you are using the original charger perhaps it is faulty (it may be damaged, broken, etc.), so to eliminate that, use a different charger and different cable.

Use Ampere

There is a handy app called Ampere that will tell you how much power your device is receiving. With this app, you will see which USB cable/charger combination is working the best for your smartphone, so it will charge faster.

Close apps which are running in the background

If you have tons of apps which are running in the background, that may be the reason why your device is charging slowly. Here is how you can close background apps:

  • Go to Settings
  • Tap Apps
  • Swipe to the left and tap select Running tab
  • You will see all the running apps
  • To close the app which is running, tap on its name and click Stop
  • You will be asked if you want to stop system service, tap Yes.

Also, try not to use your device while it’s charging because it will charge slower.


If these workarounds didn’t help you fix the problem, contact LG or your carrier.

  1. So if you are/were like me and [B]have tried pretty much everything[/B], looked everywhere (if you’re looking at an old thread like this, you’re probably desperate to find a solution), and have all the tweaks on your phone to save battery, and the advice people give about disabling wifi and bluetooth, and other[B] obvious tips[/B] that annoy the heck out of you, and you’ve looked at the health of your battery (seems fine) and other hardware related issues, but your battery still drains here’s the [B]real truth[/B].


    [U]I’ve been personally guilty of not facing the same inevitable fact[/U] in the past, but whenever you have an OS update or when things just don’t seem to work all of sudden as it did before, there’s a conflict with some of the old “stuff” in your phone and you need to clean that out. It’s not the update or the new OS that’s the problem – it’s the conflict with the old junk in your phone that’s causing the issue. My phone used to drain overnight (where when i wake up the phone is dead), but now it is at 85% when i go to sleep, 85% when i wake up 7-8 hours later. And that’s with wifi off during sleep, data/bluetooth off. You won’t get the same result unless you have the same [root] tweaks that i’ve made in other areas, but regardless, it’s not gonna go dead overnight.

    I know – it seems scary and it may take some work to get it back to where you had it, but [B]think about all the time you spent trying everything else[/B]. Just bite the bullet and get it done – i promise it will solve your battery issues.

    [U]You don’t need to wipe “system” or your internal/sd cards (don’t wipe these, in fact) – just wipe “data”, “cache” and “dalvik”.[/U] It will throw you in to the original Google/Android phone setup steps, but just go through them. Have google backup or use apps like Titanium to back up every little thing on your phone (like msgs) beforehand. If you have a launcher, you can make back up of that too. Well, this part you probably can figure out.
