How to improve charge rate on LG G4?

How can I make my LG G4 charge faster?

Convince LG to relax the temperature threshold where charging rate is reduced.

A QC charger will charge the phone at about 1.2%/min. Unfortunately that's about as good as it gets for now ( and maybe ever).

The phone charging circuit is designed to feed a fixed current into the phone (through most of the charge cycle). The maximum save current for any lithium battery is 1C - IOW, for a 3000mAh battery, 3000mA. That will charge it in about 90 minutes (due to inefficiencies in charging - electrical to chemical and chemical to electrical conversions are among the lowest efficiency energy conversions). Most phones, though, are designed to charge somewhere between 0.3 C and 0.7C, so it takes a couple to a few hours from 0 (which you should never do - 40% is about as low as you should drop a lithium battery if you want it to last a while) to 100%.

Quick Charge 2 brings the charge time down a bit, at the cost of a little battery life. I wouldn't do that to my batteries. (I still have 11 year old batteries working in an old phone that I keep as a spare.)

How long is it taking for your phone to charge? Please install GSam and post a screenshot of the chart showing a charge cycle.

+1. As tourbound129 alluded to, keep the phone cool.

The stock charger & cable will do about 1600mA. But as the phone's temperature rises, the phone will reduce the charge current, I've often seen mine fall to about 300mA.

So what the phone is capable of (I get about 1950mA with my QC 2.0 charger), and what you actually maintain during a charge, are two different things. Keep the screen turned off to reduce heat. Try to avoid apps that keep running in the background, contributing to warming the phone up.

Go on amazon. Get an Aukey quick charger. It's Qualcomm certified and on sale for like $7. Totally worth it. It's a 3,000 mah battery. A standard charger, even the one that comes with the G4 is gonna take a long time to charge. And probably won't even charge it if you're using it while it's on the charger.
