At the N14,000 ($87) retail price, the Innjoo i1s is as cheap as budget Android smartphones come. But unlike other devices within its price range, it has mind blowing specs. Well, sorta.

Over the weekend, I shared unboxing photos and my first impressions of the Innjoo i1s. But I didn’t say much about the disappointing battery capacity. I find it odd that a quad-core processor smartphone is powered by a measly 1900 mAh battery. While it’s possible it has some awesome battery optimization in place (unlikely for a budget device), there’s only so much juice you can get from such a small battery powering a quad-core. So how does it hold?

The biggest culprits of smartphone battery hogging are the display and internet. I looped 480p resolution videos on the Innjoo i1s, under 2 different scenarios. 

  • Scenario 1: Loud speakers at full volume, brightness set to 100%, and 3G mobile internet on. The battery lasted- 4 hours to 10%
  • Scenario 2:  Loud speakers at full volume, brightness set to about 50%, and 3G mobile internet on. The battery lasted- barely 5 hours to 10%

Not bad for a 1900 mAh battery. But not spectacular either. I was going to test it in a third scenario, with headsets plugged in but, for lack of time, I wasn’t able to. I might try it out some other time.

There are a couple of other real-life usage tests I’m looking to pass the Innjoo i1s through:

Gaming: This is where I use the phone at a stretch for nothing other than gaming, brightness set to high (because we like to see all the details when gaming) and mobile internet off. It will be interesting to see how long the battery will last.

Intensive Everyday Usage: This is where me and the phone are clingy best buddies for a whole day. It will hardly leave my hands. I will use it intensively for regular stuff like browsing the web, instant messaging, calling, gaming, taking photos and listening to music.

I should have these other battery time results in the coming days.

In the meantime, judging by the results above, what’s your impression of the Innjoo i1s battery life? Will 5 hours of continuous high resolution video playback be enough for you? Any other thing you’d like to know about the battery life? Let me know in the comments
