The BlackBerry DTEK60 comes with a 3,000 mAh battery providing approximately 14 hours and 45 minutes of mixed usage, around 6 hours of on-screen time, and less than 10 hours of continuous video playback.
1. In-depth Analysis of BlackBerry DTEK60 Battery Life - Nearly 15 Hours of Mixed Usage
BlackBerry DTEK60 with a 3,000 mAh battery offers up to 14 hours and 45 minutes of mixed usage, approximately 6 hours of on-screen time, and less than 10 hours of continuous video playback. BlackBerry, upon introducing the product, claimed the device could last up to 24 hours with mixed usage, but that's likely under very ideal conditions. Below is a detailed breakdown of the device's battery usage and the process I followed to achieve these results.
Specifications:
- Processor: Snapdragon 820, quad-core
- Display: 5.5' Quad HD (2560 x 1440), 534 ppi
- RAM: 4 GB
- Internal Storage: 32 GB
- Expandable Storage: microSD
- Rear Camera: 21 MP, AF, F2.0, Dual LED Flash, PDAF, 4K video recording
- Front Camera: 8 MP, FF, F2.2
- Battery: 3,000 mAh, Quick Charge 3.0 support
Experiment Parameters:
- Using stock Android 6.0.1 without customization, not rooted.
- Screen brightness set at 50% (no auto brightness). Wifi + 3G + Location + Sync always on.
- Testing environment: outdoor temperature ranging from 27°C to 31°C (throughout the day).
- Software used during testing: Facebook, Messenger (FB), Stock Browser (Chrome), Asphalt 8, CPU-Z, Battery Widget, MX Player.
Testing Procedure:
- Testing each task for 30 minutes until battery depletion including: web browsing (web + chat + fb + news reading), watching Youtube, playing game (Asphalt 8), all done via Wifi.
- Standby process includes continuous mail push, receiving Facebook messages.
- Continuous movie playback, tested movie is The Jungle Book 720p x264.
Mixed usage lasted 14 hours 45 minutes, on screen time 5 hours 54 minutes
Clearly, if BlackBerry equipped the DTEK60 with a larger battery, things would be smoother. DTEK60 boasts powerful specs which can put pressure on the 3,000 mAh battery. Through testing, the device managed to achieve 5 hours 54 minutes of on-screen time, hence resulting in a mixed usage time of up to 14 hours 45 minutes. While not overly impressive, I believe it's sufficient for the majority of users, except for those demanding heavy continuous gaming. With such mixed usage time, one can envision charging the device fully and unplugging it at 7 am, only to exhaust the battery by 9:45 pm.
These are just general figures, so the actual usage time of the device will depend greatly on your usage habits as well. One notable drawback during usage is that the device gets very hot, even when performing lighter tasks like watching Youtube. During gaming, the temperature of the device can sometimes reach up to 47°C, making it uncomfortable for users to hold or answer calls at that time as they have to press their ears against the hot phone.
Continuous movie playback time is 9 hours 44 minutes
Through testing, the device achieved approximately 9 hours 44 minutes of continuous movie playback. Regarding charging speed, using the included charger, the time it takes to charge from empty to 100% is around 3 hours 14 minutes. I believe if we were to purchase an additional charger supporting Quick Charge 3.0, the charging time would significantly decrease.
