Best "Battery Warrior" Smartphones To Buy in 2024

Smartphones are getting better by the day when it comes to aspects like cameras, software and designs across all price segments.

But one thing that people seem to forget is how much battery has become a sector that these brands are competing in.

And it’s not just about the battery capacity but also factors like charging speed and other innovative charging tech like wireless and reverse charging.

So this list makes sure to cater to all these aspects in trying to figure out the smartphones in the 2024 market that offer the best value.

iPhone 15 Plus (KES 120,000-130,000)

This is a phone that has been described by many as an outright clone of the iPhone 14 Pro. But that isn’t a bad thing in my opinion, since you’re getting the Pro-level upgrades at a lower price.

The battery is one of the few features that makes the iPhone 15 Plus stand out among the iPhone 15 series despite not being the top sibling. Despite having a mere 4383mAh battery, the device has been touted by many as one that holds its own as it doesn’t demand too much power in comparison to the 15 Pros.

It’s safe to assume that the currently most expensive non-foldable Samsung smartphone offers one of the best battery lives.

OnePlus 12 (KES 90,000-95,000)

OnePlus’ reputation over the years has always been the “flagship killer” and the 12 model definitely lives up to the trend despite selling at “flagship prices” in the Kenyan market through third-party retailers. One of the standout features with this device is the 5,400mAh battery which we don’t get to see enough with phones in this price segment unfortunately.

OPPO Reno 11 F (KES 48,000-50,000)

This midranger is quite fascinating as it actually holds a 5000mAh battery that is bigger compared to that of Reno 11 and Reno 11 Pro which cost more. The battery will give you about 8 hours on a single charge which should be enough for most users as a daily smartphone. The device also supports 67W SuperVOOC charging that juices up the phone to 100% in under 45 minutes. A 30-minute charge can get it to 80%.

Redmi Note 13 Pro 5G (KES 40,000-42,000)

When it comes to the midrange segment, this will most likely be the one device with the biggest battery which says alot about what it offers. The phone comes with a whopping 5,100mAh battery with 67W charging that guarantees you enough screen time and also fast charging from 0-100%. So, it’s safe to assume that not many users would have too many complaints about power with the Redmi Note 13 Pro 5G.

Infinix Note 40 Pro (KES 38,000)

When it comes to innovative charging tech that I mentioned before, this is probably one of the few handsets in the list that lives up to the expectations since we don’t get to see alot of charging features in this price segment. Other than the 5000mAh battery, you get to have a charging pad that also comes with a specially designed phone case for that, reverse wireless charging, 45W wired charging and bypass charging.
