A smartphone’s battery capacity is a deal-breaker aspect for many potential buyers. Some original equipment manufacturers (OEMs) place huge battery units in the device to get prolonged battery life. Others settle for modest battery units -- and make compromises like reducing the screen resolution to sustain the battery life. And in some other cases, the in-built software is tweaked to get the desired result. In any case, the retention of the battery life depends on the configuration of the handset.
According to Phone Arena, Qualcomm was reportedly the first chipmaker to bring in the quick-charging capability to smartphones with the help of QuickCharge 1.0 technology. Apparently, the first-generation technology rolled out in 2012 reduced the charging time by nearly 40 percent. Then came Qualcomm's QuickCharge 2.0 technology and this was reportedly part of the Snapdragon 800 SoC. Following the path set by Qualcomm, Chinese OEM Oppo came up with the VOOC chargers seen in the Oppo Find 7 smartphones. Notably, the Find 7 is one of the quickest-charging high-end phones available today.
Meanwhile, the Oppo Find 7 takes about 1 hour, 22 minutes to get a full recharge. Plus, the new device to get added to the list of top 5 smartphones of 2015/2014 is Samsung’s 2015 flagship Galaxy S6. Notably, the Galaxy S6 comes with “Fast Adaptive Charging” technology. This handset has trumped all other devices in the custom test conducted by Phone Arena. The Samsung Galaxy S6 reportedly goes from 0 percent to 100 percent in 1 hour, 18 minutes. Interestingly, this Fast Adaptive Charging option was first introduced by Samsung in the 2014 phablet Galaxy Note 4. Here is the list of the top 5 smartphones of 2015/2014 that can be charged rapidly.
1. Samsung Galaxy S6 (1 Hour, 18 Minutes)
The Galaxy S6 comes equipped with a modest 2,550 mAh battery unit. However, the aforementioned Fast Adaptive Charging aspect helps the device get a full charge within 1 hour and 18 minutes. Reportedly, the handset can sustain the charge for 7 hours and 14 minutes.
2. Oppo Find 7a (1 Hour, 22 Minutes)
The underdog Oppo Find 7a features a 2,800 mAh battery unit. The charging time taken by the handset from 0 percent to 100 percent is only 1 hour and 22 minutes. Notably, this device uses VOOC technology. As a result, the battery charge can be retained for reportedly 6 hours and 6 minutes.
3. Samsung Galaxy Note 4 (1 Hour, 35 Minutes)
A humongous 3,220 mAh battery unit is housed in the behemoth Samsung Galaxy Note 4. Similar to the Galaxy S6, the Note 4 also comes with the Fast Adaptive Charging feature. Therefore, the device can be fully charged within 1 hour and 35 minutes. And the battery life can be maintained for apparently 8 hours and 43 minutes.
4. Motorola Nexus 6 (1 Hour, 38 Minutes)
The Nexus 6 also comes with the same battery capacity seen in the Note 4 i.e. 3,220 mAh unit, but the technology used is Motorola Turbo Charger, according to Phone Arena. But then, the charging time reportedly is 1 hour and 38 minutes and the battery life retention time is 7 hours and 53 minutes.
5. HTC One M9 (1 Hour, 46 Minutes)
The battery capacity of the 2015 flagship HTC One M9 is only a modest 2,840 mAh unit. Nevertheless, the QuickCharge 2.0 technology on the device charges the battery from 0 percent to 100 percent within 1 hour and 46 minutes. Plus, the One M9 apparently retains the charge for up to 6 hours and 25 minutes.
