Battery & Charger
The ASUS ZenFone 5 comes at a more modest 3,400mAh battery instead of the humongous one that its brethren is equipped with.
We tested the ZenFone 5 in two scenarios – with and without AI Boost. In our section where we talked about the performance of the ZenFone 5, we realized that AI Boost did affect the performance – but does it affect the battery life of the phone? Take a look at this chart.
For some reason, the ZenFone 5 has a shorter battery life when AI Boost is turned on. That’s an interesting point to take note of.
When it comes to the charger, we also have two scenarios – with and without AI Charging feature. It is something that “learns user’s charging and usage patterns” so that the phone’s life span can be preserved as it doesn’t enter trickle charging that quickly.
How it works is quite simple. For example, if you leave your phone plugged in from 10pm to 7am everyday, then it’ll charge as usual at 10pm. However, it won’t continue to charge once it reaches 80% battery. It’ll idle until about a given time, then continues charging to achieve 100% battery at 7am.
Of course, the AI Charging will definitely take time to learn the user’s charging behavior. The more days you use it consistently, the better it gets. From what we can test, it did show some changes in the charging curve.
With the 5V 2A charger that is included in the box, this is the charging curve where we compare with and without AI Charging. Honestly, we’re charging it really inconsistently now since we’re testing the ZenFone 5 in an aggressive manner. Perhaps we’ll revisit the AI Charging again in the future.
