Living with a huge, 5000mAh-battery phone, and why 1000-dollar phones don't have one
Now, if you want to learn more about the ZenFone 6 as a whole, I encourage you to read my ZenFone 6 Preview article where I share my initial thoughts and first-hand impressions. Here, I will focus on one particular aspect of the device – its battery life – and how it has affected me as a user.
This thing lasts forever!
Case in point, the Asus ZenFone 6 can easily last me two to three days on one charge. I get a day and a half to two days from most other phones. I admit that I'm not the heaviest of users, but the leap in battery life compared to anything I've used recently is definitely there. It's a difference you'd most certainly feel, no matter how demanding of a user you are.
The not-so-obvious benefits of having a huge battery
Having your phone last forever is awesome, and so is knowing that you can go on a flight or explore the great outdoors without having to lug a power bank along. But the benefits of having a huge battery do not end here.
Since I started using the ZenFone 6, I noticed that battery anxiety as a whole is no longer a thing for me. Surveys show that a significant portion of people feel elevated stress levels when they're away from an outlet and their phone's battery is getting low, and being less stressed is something few people would mind, I'm sure.
My charging habits have also shifted. Until recently, I'd usually let my phone charge overnight so that I know I have a full charge at the start of the day. An incomplete charge would somehow feel wrong with any other phone, but with the ZenFone 6, even a quick, 30% burst at any point during the day means up to an extra day of usage, so I do not feel obligated to charge it religiously every night.
And on the technical side of things, bigger batteries do tend to have a longer lifespan. This makes perfect sense as batteries degrade after each charge-discharge cycle, and about 500 charges is enough for a cell to lose 20% of its original capacity. Having to recharge your phone less often means it takes longer to reach that threshold. In Asus's lab tests, the battery in the ZenFone 6 retained 90% of its charge capacity after simulated 2 years of use while the 3300mAh cell of an unnamed competitor could hold 85% after the same stress test.
So, why don't all phones have batteries this big?
But it is a different story with phones made for the masses. For example, a phone like the Samsung Galaxy S10+ needs to strike an emotional chord with a potential buyer when they pick it up at the store. For this particular person, numbers on paper may be less important than the way a phone looks and feels in the hand, not to mention that a bigger battery makes for a thicker, heavier, less elegant phone.
Speaking of thickness, for me, this is the only major downside to having a battery so big. The ZenFone 6 is considerably chunky and quite heavy in the hand, especially when you slap a case on it. And now that I've used it for a while, I feel like I wouldn't mind trading some of that battery life to make room for better speakers and a bigger vibration motor.
