Charging the LG G3 = Long and Painful!

[dmullins8]

Mine takes no where near that long. I would definitely get a replacement.

First, the G3 is neither slow nor particularly fast to charge.

AnandTech | The LG G3 Review

"In this test, the LG G3 trails behind both the One (M8) and Galaxy S5 in charge time, although it's quite close to the One (M8). This is strange, especially because the LG G2 has the same battery size. However, this can be explained by the change to charging protocol, as it seems that the G3 doesn't support Qualcomm's Quick Charge technology. Instead, signalling is done over BC 1.2. As we'll see later in the article, this is due to the charger chip used." - from the article

^^^ That means that you probably won't see it charge at a faster rate when it's closer to dead.

Second, the reason a 2.4A charger could theoretically charge faster than 1.8A even though the phone might only pull 1.8A max is efficiency. The LG charger might only be, say, 90% efficient (I'm really just making the numbers up) which means it's not actually putting out 1.8A, more like ~1.62A. If you get a 2.4A charger that's capable of even 80% efficiency (again, making that number up) it'll put out realistic ~1.92A. That would mean that it could give the phone a bit more juice.

That being said, .18-.2A is not going to make the phone charge in half the time some of you are saying that it takes. If you're actively using the phone while charging there is a possibility that your phone won't charge at all depending on what you're doing. If you're plugging in it overnight for 5-6 hours and using the stock LG charger that came with the phone there's no reason it shouldn't be fully charged. Something is defective. If a new charger fixed it, than your charger is most likely defective.

Mini chargers tend to be specced like they have terrible efficiency. Some are not even 50% effective. But the OUTPUT amperage should be guaranteed. Same as a PC PSU maker gets into trouble when its 15A +12v rail dies at only 10A, branded chargers should deliver up to or beyond the numbers printed on them. Cheap 3rd party models may be as treacherous as a $30 'Sunbeam' transformer. :/

Just upgraded from the G2 to the G3. Mine also appears to be charging slow. I'm using the 1.8A from my G2 so I know its not the charger. G2 charged ridiculously quick. This phone is barely charging while I use it and will take 4 hours to fully charge from 5%. Granted I've been using it most of this time to surf internet but screen at 20% brightness. Getting a stronger charger is not the right answer.

 

[hanzel81]

I guess anandtech's review had a total charging time of 2.8 hours. Guess 4 hours while using it would be comparable. Guess people are exaggerating some with the "90 min" charge times.

try to use other fast charger..

I had a problem with my igo dual USB 2.1A total output charger. I picked up a 4.8A charger dual USB on amazon and it works well for me. I need dual USB. One for my work phone and one for my personal phone and its easier when hotels only usually have one outlet bear the bed.

Didn't go through the entire thread but read this... took them 2.8 hours?!

No way that's normal cause mine will basically charge 50% per hour with the supplied charger. And don't notice it charging any slower than my G2 did. I think 2 hours for phone is decent.

Mine takes about 2hr 30min to fully charge and that's not using it.

I am not really sure what happened, but my G3 was at ~10% at midnight when I put it on the charger, and when I woke up at 6AM, it was only charged to 80% using the OEM charger.

I just rooted yesterday and installed Greenify, Lux, GSam Battery Monitor, and switched to Art. Not sure if one of those things caused my poor charging? Idk, I will try again tonight.

This is your problem I'm afraid.

This is your problem I'm afraid.

How so? I have read of people getting 20-40hr battery lifes with rooted G3 and some tweaks. I don't think everyone has slow charging issues just because they rooted...

 

[hanzel81]

Thanks for the feedback. I'll see what it takes tonight to fully charge without use.

 

[Nreeldeep]

I am charging my LG G3 from 4AM at 14% Battery Life got up at 8:30AM battery is on 57%!
Could anybody explain me why it takes so loooooong to charge a stupid battery? In this time my LG G2 was charged already while on the LG G3 I am not even half charged!
Is there a problem?
Anybody has a batter or faster charger?
Please help

P.s. Yes! I am using the charger it came with the G3/G2 (same 1.8Amp Charger)

My wife had a g3 for a week. It had a lot of other problems but charging wasn't one of them. It charged as quick as anything else we've ever owned. The charging speed was impressive, even when surfing while charging.

Your issue is either a bad root or something you installed. Also, its been know that ART messes with the G3. Not sure how well it works with root though. Try reflashing and starting all over again if anything.

I couldn't care less about anandtech's or any other person's conclusion about a mobile device. I'm just as able to come up with my own conclusions based on my own tests, which are much more valid than some dude on a website offering his own personal opinions from a single device he tested. His own personal tastes and biases play a part. I can charge a phone just like he can.
If people's devices are charging slowly, that means they're charging slowly. Out of a million devices coming off the assembly line, there are going to be variances in performance and build quality. Anandtech chose one that charges quickly. My wife did also. Obviously people purchased devices that charged slowly out of the box. Their concerns are valid.

Thanks, I used IORoot to root and everything seemed to go ok. I think I am going to switch back to Dalvik and see how that pans out

Let us know how it works out for you! Good luck!

Charging time is something that can be measured repeatedly and is not subject to opinion. I have a G3, and can confirm the results of that charge time test. I'm sure others can as well. If someone's phone is charging at a significantly slower rate than is being reported by a majority of users they probably have a defective device and/or charger.

Now, depending on what device a person came from could affect the perception of the charge time. Coming from the M8 and S5, the G3 feels like it charges much slower, even though it's pretty neck and neck with the M8. Could be an affect of the quick charge tech from Qualcomm increasing the charge rate when the battery is lower. Could be something else. Doesn't change the fact that it does in fact charge slower and that for me it feels significantly slower because of my prior experiences.

 

[hanzel81]

Agreed Kevin. Charging time should not vary much from unit to unit (using std 1.8A charger). Its a physical quality of the phone, much like other benchmarks. Thus the reason I quoted anandtech. Obviously all reviews have bias. Its up to the reader to filter this and look at them objectively.

 

[ranger29]

Just got my G3 and wondered...does anyone else think it is really hard to put the charger into the device? Maybe I am just use to my S4 being "loose" but it just seems like its really tough connecting the charger...at first I thought I had it going in the wrong side up but I was wrong.

Mine also is hard to put in. Thought about returning it and getting a different phone, as I don't want to break the internals. But I think it's been getting easier. Mine takes only about an hour to charge from say 10% to 100%, which suprised me. Using the charger that came in the box.
