OnePlus 5 Battery Review: Surprisingly efficient for a flagship phone

Featured, Technology No Comments on OnePlus 5 Battery Review: Surprisingly efficient for a flagship phone 1

After mostly positive reviews of the OnePlus 5, the phone continues to gain attention among buyers. Priced from Rs 32,999, the OnePlus 5 comes with the Qualcomm Snapdragon 835 SoC and either 6GB or 8GB of RAM, which offers top-level performance. We’ve comprehensively reviewed the OnePlus 5, and it remains our top recommendation for flagship smartphones today.

But with all that power comes the assumption of poor battery life. After all, this has been the norm with flagship smartphones, which are not typically known for good battery life, simply because of all the energy required to power everything from the flagship SoC to the typically high-resolution screen. We’ve been using the OnePlus 5 for a while now, and here are our insights on what to expect from the phone when it comes to battery life.

OnePlus 5 Battery

The OnePlus 5 is backed by a 3,300mAh battery, which is a little bit less than the one on the OnePlus 3T. However, the phone does sport better hardware and components, allowing it to utilize the power at hand in a more efficient and effective manner. It’s possible to use the phone for a full day on a single charge, even with heavy usage. During my over one month with the phone, I haven’t once run low on battery, even when I started the day with a full charge.

This can largely be credited to the Qualcomm Snapdragon 835 SoC under the hood. Fabricated on the 10nm process, the flagship chipset offers about 30 percent better performance, while using 25 percent less power than the Snapdragon 821, according to Qualcomm. These figures aren’t inaccurate; this is something that I have experienced, and in practicality, the Snapdragon 835 is a superior chipset in every way.

Power consumption is significantly lower in all regards, but shows particularly when it comes to intensive tasks. Gaming, multi-tasking, and increased use of the screen have a much smaller impact on the battery than with other phones I’ve used. Also helping is the fact that the phone has enough RAM at its disposal, as well as the AMOLED full-HD screen, which isn’t quite as power-hungry as the QHD or higher IPS-LCD screens on some other smartphones.

Long gaming sessions with graphics-intensive games such as Riptide GP and Hungry Shark World don’t cause the battery to drop as quickly as we’re used to, and watching videos on Netflix or YouTube also see the battery ticking down slowly. This allows for much more practical use of the phone, with you able to tap all of the power at hand as often as you like, without worrying too much about running out. I’ve also regularly seen a screen-on time in excess of five hours on a full charge, with some occasions going as high as seven hours.OnePlus 5 dash Charge against Samsung Galaxy S8

Dash Charge dashes as fast as ever

OnePlus premiered its Dash Charge fast-charging technology in 2016 with the OnePlus 3, and indeed doesn’t see any change even today, essentially using the same technology as Oppo‘s VOOC charging. Although the charger is physically large and has a formidable and somewhat scary 5V/4A specification, it’s a small price to pay for what you get. Going from 0-100 percent in just about an hour, the phone is easy to charge and doesn’t need you to keep it plugged in all night, as was the case as recently as two years ago.

This can also have a profound effect on your charging habits, and lets you worry much less about your battery levels. Charging for 10-15 minutes when the battery is low can add as much as 40-50 percent to your battery, letting you charge in bursts as and when you need it. I often gave it about 10-15 minutes of charge while I was in the shower every morning, and then perhaps another 30-40 minutes at night before sleeping, which would be sufficient. On occasions, I’ve also been able to use my OnePlus 3 Car Dash Charger for quick bursts of power. This new form of charging is a refreshing one, and something I’ve now gotten used to.

Final Thoughts

With flagship phones, we’ve come to assume that battery life will be poor. Powerful phones with high-resolution screens are assumed to draw more power, and intensive tasks such as gaming, multi-tasking and video streaming tend to have a stronger impact on the battery. It’s therefore a refreshing change to see the OnePlus 5 go against many of those norms.

With the excellent Qualcomm Snapdragon 835 SoC, enough RAM and a reasonable full-HD AMOLED screen, the OnePlus 5 makes the most of its 3,300mAh battery. It gets you through the day thanks to efficient usage of the battery, and the highly optimized OxygenOS also works well to keep battery usage sensible. The icing on the cake remains Dash Charge, which allows fast charging and will help you change your charging habits for the better.
