Battery technology has not changed much since the debut of the first mobile phone, but progress has been made on the front of the refill, with much more advanced systems and SoC ready to support the greater input of electricity. All major manufacturers allow now to achieve acceptable levels of loads in a matter of minutes, several approaches to such an outcome. But similar, not identical.
To find out what the device cannot charge more quickly have been compared some of the top range 2015, namely Asus Zenfone 2 (3000mAh), Google Nexus 6 (3220mAh), OnePlus 2 (3300mAh), Samsung Galaxy S6 (2550), LG G4 (3000mAh), Motorola Droid Turbo (3900mAh) and iPhone 6 (1810mAh). Is not a linear race, fast-charging systems are what ensure greater results in the first few minutes, others appear on the ‘ long distance. Things to emphasize that many of these use the Qualcomm Quick Charge 2.0, capable of supporting voltages on 9-volt/1.67-amp, far beyond the 5-volt/1.5-amp used by Apple to charge iPhone 6 and 6 Plus.
To bring all the terminals at the same level were pushed until it is switched off, then get charged up to 5% and determined this starting point, with 5, 15 and 30 minute test. Let’s see who won the day.
After 5 Minutes
On the short distance to surprise everyone is Asus with its Zenfone 2, able even to reach the 17% charged due to its ‘ Boostmaster technology ‘. Much more detached from everyone else, with Nexus 6 and 12% at 2 and all other OnePlus (except iPhone 6) to 11%, with the melafonino lagging behind at 6%.
After 15 Minutes
Having regard to the departure of sprint Asus Zenfone 2 is not surprising to see him back in the lead after 15 minutes of charging, that is enough to reach 32% charge, but Samsung manages to keep up with Galaxy S6, according to 27%. Slightly lose ground every other, with 25%, 6 third G4 the Nexus 23% and 22%, boost Droid instead Apple, yet last but with a respectable 20% like OnePlus 2. The latter was able to add only 8 percentage points in 10 minutes.
After 30 Minutes
Samsung proves up to the challenge, after half an hour of charging is indeed well before charging with 53 percentage points, same as excellent Asus Zenfone 2. It is confirmed in the third position the Nexus 6 thanks to a good 44% charge reached, like the G4 with 42%. Follows the Droid and iPhone 6, turbocharged with 38% finally out from the last position (36%), where it is relegated One Plus 2 with only 34% charge, almost 1% per minute.
After the first three tests it has been calculated the time it takes for the terminals to reach the80% charge, reminding everyone that the terminals have different capacities, you switch from the Turbo to the Motorola Droid 1810mAh 3900mAh dell’iphone 6. In the long run theGalaxy S6 is what can achieve faster this level, it takes only 48 minutes, against 56 min Zenfone 2 and 60 min of Nexus 6. Good also the result of LG G4 (62 min), while 2 with its 85-minute raw OnePlus, still in last place (our review ).
Last detection is obviously made to 100% of the charge, and surprises abound. Samsung closes first with 82 minutes, Second, surprisingly, LG G4 with 96 minutes, the two Korean homes do not provide an absolute sprint in early stages but guarantee a constant rapid charging. Third the Motorola Droid Turbo with 107 minutes required to load a large battery, very close Nexus 6 and Zenfone 2 in 109 minutes.
Detached OnePlus 2 and iPhone 6, the two terminals need respectively 2:10 and 2:35 hours for a full charge, definitely too much given the competition.
Samsung comes out on top, but is Asus to victorious given its 53 milliamps per minute in the first half hour, the more important it is to have to reload quickly and exploit this potential.Considerable even the Motorola Droid Turbo, capable of close to third place at the end of the first half and add 49.4 milliamps.
