Which top-of-the-range smartphone is the fastest charging?

There's no getting around the fact that smartphones eat up a lot of battery power. There are plenty of good reasons for this – the devices are very advanced and more like small computers than simple phones. 

With internet access and apps that offer games and services, the smartphone has become an essential part of daily life. However, charging is more of an active consideration than in the past. Long gone are the days of the old Nokia feature phones that could last around a week on a single charge. 

Long battery life does count for a lot, but with frequent, small bursts of charging becoming more commonplace, it is important to bear in mind how quickly a smartphone is able to charge. For instance, when a phone is low on power, but you only have a few minutes before you are due to leave the house or catch a train, the speed at which the device can pick up power is crucial. 

With this in mind, Tom's Guide tested some of the most popular smartphones currently on the market, pitting them against one another in an effort to establish which is the most efficient in terms of charging time. 

The Asus Zenfone 2 was found to offer the most power in the shortest amount of charge time, but the Samsung Galaxy S6 was joint top with that device in terms of how much power it could gain in half an hour, as well as being joint fastest to get up to 80 per cent battery life. 

Asus Zenfone 2 

After five minutes, the Asus Zenfone 2 was able to get to 17 per cent charge from zero. This is a whole five per cent higher than the average charge of 11.43 per cent in this short space of time. 

After 15 minutes, it was able to get up to 32 per cent charged, a full five per cent higher than its nearest rival, the Samsung Galaxy S6. 

However, it started to lose ground to the Galaxy in terms of reaching a higher charge, taking 56 minutes to reach 80 per cent and one hour and 49 minutes for 100 per cent. 

Samsung Galaxy S6 

The Samsung Galaxy was close behind the Asus Zenfone 2 when it came to the low end of charge speed, reaching 11 per cent charge in five minutes and 27 per cent in quarter of an hour. 

After half an hour of charging, it tied with the Asus device at 53 per cent charged, and started to inch past it for higher levels of battery power. 

It reached 80 per cent battery life in just 48 minutes and was fully charged in one hour and 22 minutes – the fastest of all tested models on both counts. 

Google Nexus 6

The Google Nexus 6 was second behind the Asus Zenfone after five minutes of charging, reaching 12 per cent – the same score as the OnePlus 2. 

After 15 minutes and half an hour, it was third after the Asus and the Samsung Galaxy 6, reaching 25 per cent and 44 per cent charge respectively. 

It also ranked third to reach 80 per cent battery life, taking a full hour – and the last stretch to full power took it one hour and 49 minutes. 

Apple iPhone 6

Despite its consistent popularity, the Apple iPhone proved to be the lowest performer at every level of charge. It was only on six per cent battery life after five minutes, 20 per cent after 15 and 36 per cent after half an hour. 

It took one hour and fifteen minutes to reach 80 per cent and two hours, 35 minutes for full power.ADNFCR-2155-ID-801799082-ADNFCR
