Fast chargers

Hey people,
Before I went out and bought a car charger and second wall charger, I was wondering if you guys knew what the fastest ones were. I was using my friends car charger the other day and it literally did almost nothing for 20 minutes. The battery went up 1% every 15-20 minutes or so.

It's probably an issue with the cars 12v port, not the charger itself. No matter what your phone should charge around 3.7v. If you plug in a charger that has a higher output to try and speed charge it the phone and the battery have built in protection to keep it from charging above the recommended 3.7v. So just buy a reliable cellphone charger and don't fall for speedcharging gimmicks

I remember back when the iPad first came out there was a rumor that using an iPad charger to charge an iPhone would charge it faster, but the device only pulls what it needs (if it's designed well). I believe charging a device at a lower voltage may make it charge slower, but you can never speed it up unless the battery specifically possesses control circutry to do so. See http://en.wikipedia.org/wiki/Battery_charger#Fast.

Odd battery issues...

Ok so I have a Hyperion 2200mah battery, when I charge it up inside my phone, my led does not turn green and finish charging. This is opposed to my stock which works perfectly. Also, when I remove the cord when using the Hyperion, the battery is at like ~85% and it slowly works its way up to ~90% in 10 minutes or so and then starts discharging normally from there. HOWEVER, when I charge the Hyperion I'm my stand alone battery charger, it charges to like 98%. Is my Hyperion faulty or do they all act like this? I've had no similar problems with stock.

Here's an example of how it appears on the battery info

It appears that it does fully charge but it doesn't switch to ac power properly or something... and starts dropping idk

I have the same battery and I have seen the same behavior. I bought a two pack of the batteries with a standalone wall charger from Hyperion on Amazon.
I have found that if I charge the battery in the phone overnight it will nearly reach a full charge and then drop off to around 80%. It will then stay at that level as long as the charger is attached (see attached screenshot).
If I charge in the standalone wall charger that came with the batteries it will reach full charge (as indicated by the charger and the phone when I install the battery) but it will drop to 97% very quickly (within minutes).
It is as if the batteries are not truly compatible with the phone. It may have something to do with the difference in voltage (3.8v for Samsung vs 3.7v for Hyperion). I wonder if this difference is confusing the battery charger in the phone.
That is not the only problem that I have with the batteries. They are also thicker than the stock battery (5.85mm Hyperion vs 5.15mm Samsung). This causes the back cover to bulge a bit and makes my case difficult to place on the phone.
I am not too happy with these batteries and I am probably going to try to return them.

Charging batteries?

Does charging my phone directly with the usb port charge the battery better than when a battery is charged on a wall charger? I've been having bad battery problems with all. 5 of my batteries (including a 3500 mah one) and I'm starting to think that when I charge my phone whatever battery is in it last longer than if it was charged on the wall charger. Can anyone confirm that this may be true?

I recall reading somewhere that charging through USB has a chance of overcharging the battery because the wall charger has an auto cutoff when the battery reaches 100% and the USB does not. This may have something to do with possible better battery life when charging through USB. Have you tried draining the phone all the way down to 1% or until it shuts off then charging it to 100% a couple times?

I pretty much do that because I keep the battery in until my phone dies then just switch batteries. Whatever battery ends up in my phone by the end of the day gets charged by usb in my phone and any other batteries that died during the day get charged on the wall charger. But what your saying may be true because on the wall charger usually I find the batteries only 96~98% never actually 100%. Ill test it out and see what happens. Anyone know of a wall charger that works really well?

It would be nice if I could find the articles I read on the matter for some weight, rather than just my comment. But anyways....
The battery is never at 100%; that is for safety reasons. Whether USB or wall charged, it won't hit 100.

[Q] Hi guys, few questions battery life and charger.

hey guys, I just got this LG Optimus G pro off of Craigslist, and while I'm sure that the phonewas worth the deal, I just got a few questions.
1.the battery life. I've been using it constantly, and I've managed to get it up to about 75 percent battery. When I check my battery usage,it says that I have about 4 to 5 hours of used before it dies. Is this normal? I'll read the reviews and it said that this thing had an awesome battery. I went ahead and ordered some brand of battery (lemon-something) that came with 2 standard amp batteries and a wall socket battery charger. so do I need these batteries because mine is drained or is that normal?
2. the wall charger. I do not currently have the original manufacturer charger, but I am using a LG branded wall block, with a SamsungUSB. It seems to charge it okay, but when I'll plug it in I've got to tilt it up just a bit, and then it will start charging, even after I let it go. I had some generic Motorola Droid charger plugged up to it, I didn't have to wiggle it around at all, but I had to quit using it because it didn't have enough output voltage to charge the phone. Is this an issue with my charging port, or just not having the original manufacturer charger and charging cable?
thank you so much for any replies and taking time out of your day to help me.

The battery life is awesome on here. Yes, it's probably because of your USB cable. I haven't used anything but the charger my phones have come with for well over a year and all worked perfectly. When it says 4-5 hours of use, that means actually using the phone. Not standby. Not sure how well the 3.1amp ZL batteries perform, but I have the 9300mAh one and I'm loving it. Days on a single charge and comes with a TPU case.

1) Battery life IS awesome. Turn on Quad Core Control in Battery settings to make the most out of your phone.
2) I also bought mine 2nd hand without the original charger. You only have to replace your USB cable coz it's probably worn out. I've used all sorts of chargers (generic car charger, samsung, nokia) and never had a problem with any of them.

I second the idea that at usb cable is bad.Im using a generic ul last for sb cord right now and it charges just fine and the charge will last for a full day or more depending on use

Charge Zerolemon in under 9 hrs.

I searched for a solution and bought these two items..
Anker® 40W 5V / 8A 5-Port
http://www.amazon.com/gp/product/B00GTGETFG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
Mediabridge USB 2.0 - Micro-USB to USB Coiled Charging Cable
http://www.amazon.com/gp/product/B009W34X5O/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1
Now here's the kicker... It's currently unavailable...but two days ago when I wanted to make this thread is was not even listed on Amazon, so possible restocking ? I don't know.
I killed my battery to the point of total shut down by about midnight Saturday night. When I got up about 930 am I was fully charged. Now I know we've seen longer run times leaving the charger on after 100% pops up, so to speak to that I am on 94hrs run time and have forgotten how to check Screen On Time...

I am now at that dreadfully annoying -10% level. So I can use the phone all day on 100% brightness but it will chime in all day to warn me of the coming Powerpocalypse to come :laugh:

If you rooted your device you can put an xposed module on that will eliminate all low battery warnings.
On your setup, I don't really see the difference between it and using the OGP's standard high-power charger. The cable isn't going to do anything, as far as I can see. And the charging port is 8A/5 ports — from what I've read it adapts to the device to allow it to pull what it needs within that allotment, thus I don't see the OGP pulling more than 1.8A. So, my question to you is, you've tested the standard 1.8A charger against your setup and you get X hours reduction on charge time?
FYI, I don't have the ZeroLemon pack. Thinking about it but might upgrade my device to the GP2.

I have, it took a day and a half.

36 hours to charge?
Most using this pack state around 12 hours. Seems something is wrong if it's taking 36 hours to charge with the standard charger that comes with the OGP — normal battery charges in less than 3 hours. I've seen where some zerolemon packs hit 100% but are actually only half charged, thus causing increased charge times. . . . strange stuff.

Using Yoobao 2 Amps wall charger
My zerolemon (9000 mAh) only took 10 hrs to charge. And standard battery (3140 mAh) took 2 hrs using Yoobao 2 Amps wall charger.
I was hoping someone could tell me where to find 4A or 5A wall charger near Jakarta.

My zrrolemon zero lemon takes about 12 hours to charge AMD my standard battery takes about 2-3 hours using the stock charger
