LG G4 Needs Quick Charge 2.0 Charger For Faster Charge

May 28, 2015 - Written By Cory McNutt

The new LG G4 now officially supports Quick Charge 2.0, but in order to take full advantage of the rapid charge time, you need to use a charger that supports Quick Charge 2.0 (QC2.0) – the normal stock charger will not get the trick done.  The stock charger will take the LG G4 an incredibly long 127 minutes to charge its 3000mAh battery, however, using the Motorola Turbo charger, the time was reduced to 98 minutes…a 23-percent improvement over the stock charger.  However, we must point out that after just 10 minutes of charging there was a 15-percent charge and after 30 minutes it went up to 39-percent and so on until it reached 85-percent in one hour and nine minutes…after that, the charging rate dropped to slowly top off the battery in an effort to help preserve its useful life.

Our source also noted that even though the Rapid Charger shipped with the Samsung Galaxy S6 and Galaxy S6 Edge is not advertised as a QC2.0 charger, it yielded the same results.  This is not surprising as it is rated the same 15 watts as the Motorola Turbo Charger, although some third-party QC2.0 chargers are rated as high as 18 watts and should yield even faster results.  What is also interesting to note is that when the LG G4 was first announced, they did not have the Quick Charge capability, even though their Qualcomm 808 processor supports the feature.

We had reached out Qualcomm about it and they confirmed that LG decided not to include Quick Charge 2.0 in the G4 – to cut costs, because it has a removable battery or because LG was planning to sell a folio case that supported Quick Charge 2.0 – we were not sure.  A week later, LG said that they omitted the feature because the LG G4 has a removable battery and they felt that Quick Charge 2.0 was unnecessary, but due to public outcry, the Quick Charge 2.0 documents are now on their site.  This was all done before the LG G4 was officially available for sale, so any one you buy should have the firmware updated and the feature available, just remember, having the proper charger will make all the difference in your charging times.
