List: CBR looks at battery life and charging speeds for major smartphones.
Today’s figures from Strategy Analytics revealed a slowdown in the smartphone market, with sales dropping by 3 percent year-on-year.
This was the first contraction in the market in history, and comes at a time where users are beginning to focus more on core features – such as battery life and charging speeds.
A uSwitch survey of British smartphone owners in August found low levels of interest in advanced and futuristic technologies, but battery life desired by 21 percent of users.
Battery life comprises a range of indicators, and phones with the same specs in some areas may still have different battery performances.
The demand and the efficiency of the CPU can change how much battery power is consumed, while the quality of the charging technology can affect how quickly a device powers up. Additionally, the size of the battery will affect how long it can go on.
For remote workers and those who do a lot of work while travelling, such as salespeople, having a reliable phone that won’t cut out can be crucial.
CBR rounds up some smartphones to consider if you are looking for a battery-friendly model.
1. Samsung Galaxy S7 edge
Samsung boasts that its Adaptive Fast Charging recharges a Galaxy S7 edge up to 50 percent in about 30 minutes, based on laboratory testing. Recombu found that a complete charge from 0-100 percent took 95 minutes.
As a larger device, the edge is able to fit in a 3600mAh battery, at the higher end of the scale, meaning it has a fairly robust battery life.
Other charging features include Samsung’s wireless charging technology, which received heavy billing in the run-up to the release of the device. The device can simply be placed on a pad, with no wires required, meaning that even though the speed of charging may not be the fastest, it is still fairly convenient.
2. Motorola X Force
The Motorola X Force went big on battery life as a selling point, with Motorola claiming that the 3760 mAh battery offers up to 48 hours of power on a mixed use profile including video, downloads and web browsing.
The device uses Motorola’s Turbo Charge feature, which uses the phone’s software to monitor the state and health of the battery. This adjusts the amount of charge delivered at each stage of the charging so that it is always charging at the optimal rate.
According to Expertreviews, the device reaches 20 percent battery in 10 minutes, 70 percent in half an hour and 92 percent in an hour. The final 8 percent takes the total time to 90 minutes.
3. Oppo (TBC)
At Mobile World Congress, Oppo unveiled a new technology called SuperVOOC which promises to be able to charge a 2500 mAh smartphone battery from empty to full in 15 minutes.
Usefully, the technology uses a standard MicroUSB or USB Type-C cable, meaning that no hardware upgrades will be needed to make it work.
Oppo has not yet revealed the device which will feature the technology, but those who have been waiting for an essentially hassle-free phone charging process should keep an eye out.
4. Asus ZenFone 2
The ZenFone 2 from Asus boasts a fairly hefty 3000mAh battery, which puts it fairly comfortably in the large category.
Its charging speeds are boosted by the ASUS BoostMaster Technology, which can get battery up to 60 percent in 39 minutes, according to Asus.
Asus also says that the BoostMaster technology will provide 4 hours of talk time (2G) in under 10 minutes of charging time.
For a full charge, it will take roughly 1.8 hours, according to Anandtech.
5. Huawei P9 Plus
Huawei’s recently launched P9 Plus packs a 3400mAh battery.
Using dual-IC Rapid Charge, the device gives users six hours of talk time after a 10-minute charge. However the company has not released figures for a full charge.
Huawei is one to watch in the battery space; in November 2015, Huawei demonstrated new batteries which achieved a charging speed 10 times faster than a standard battery, reaching about 50 percent capacity in mere minutes.
One battery had a 600 mAh capacity that can be charged to 68 percent capacity in two minutes; and another with a 3000 mAh capacity , which can be charged to 48 percent capacity in five minutes.
