Finding the Smartphone with the Battery Life You Need

Hey there! Are you frustrated with your current phone dying halfway through the day, before you’re ready to call it quits? You’re not alone. Poor battery life is one of the top pain points for smartphone owners today.

The good news is that you have more options than ever when it comes to phones with all-day battery life and beyond. In this guide, we’ll explore the key factors that make a long-lasting battery and reveal the top 5 smartphones of 2023 that go the distance. Let’s dive in!

What Matters Most for All-Day Battery Life

When trying to choose a phone that won’t leave you stranded with a dead device, there are a few key specifications and features to focus on:

Specs What to Look For
Battery Capacity A minimum of 4,000 mAh, but 5,000+ is ideal
Charging Speed 30W, 65W or faster. Avoid phones limited to slow 5W/10W charging.
Display Efficient OLED is better than LCD. A lower resolution 1080p display uses less power than 1440p.
Processor Newer processors like Snapdragon 8 Gen 2 are more efficient than older chips.
Software Well-optimized operating systems like OxygenOS extend battery life.

Let’s explore why these factors are so important for getting the most mileage from your next phone.

Battery Capacity Sets the Foundation

The battery capacity, measured in milliamp hours (mAh), determines how much total power is available on a single charge. Most modern flagship phones have batteries in the 4,000 to 5,000 mAh range.

Budget phones sometimes have even larger batteries up to 6,000 or 7,000 mAh. However, these tend to be paired with less efficient components that cancel out some of the gains.

As a rule of thumb, you should look for a phone with at least a 4,000 mAh battery for all-day life. But if you want the comfort of multi-day battery, 5,000 mAh or higher is recommended.

Phone Battery Size
iPhone 14 Plus 4,325 mAh
Pixel 7 Pro 5,000 mAh
ROG Phone 6 6,000 mAh

Of course, battery capacity doesn’t tell the whole story, which leads us to…

Faster Charging Compensates for Smaller Batteries

One shortcoming of large battery phones is long charging times. Who wants to wait 3 hours for a full charge?

This is where fast charging comes in. Phones with 30W, 65W or 100W+ wired charging can offset average battery size by juicing up quickly.

For example, the OnePlus 11 can charge its 5,000 mAh battery from 1-100% in just 20 minutes thanks to its 100W SUPERVOOC charger. That convenience helps make up for battery life that’s good, but not the absolute longest.

Phone Charging Speed 0-50% Time
iPhone 14 Plus Up to 20W 30 min
Pixel 7 Pro 30W wired 30 min
OnePlus 11 100W wired 10 min

So don’t overlook phones with fast charging, as it allows flexibility if you forget to charge overnight or need a quick top-up during your busy day.

Display Efficiency Varies Greatly

The display is one of the most power-hungry components on a smartphone. A phone with an inefficient display will struggle to last through a full day, even with a large battery.

OLED displays are much more efficient than traditional LCDs. OLED only lights up the pixels it needs, while LCD has to constantly light the entire display.

Furthermore, a lower 1080p resolution consumes less energy than a 1440p or 4K display. Those extra pixels have to be powered!

Here are some display power consumption estimates:

Display Power Consumption
6.7" 1440p OLED, 120Hz High
6.7” 1080p OLED, 60Hz Medium
6.7” 1080p LCD, 60Hz Medium-High

Of course, you likely don’t want to sacrifice screen quality solely for battery life. The good news is you can find phones like the iPhone 14 Plus that strike a nice balance with an efficient OLED display at 1080p resolution.

Software and Hardware Optimization Matters Too

A phone’s battery size doesn’t tell the whole story. The processor, RAM, and software experience also play a big role in efficiency and battery life.

As a general rule:

  • Newer processors like the Snapdragon 8 Gen 2 are more efficient than older chips. They utilize larger, more advanced manufacturing processes to save power.
  • Well optimized operating systems like OxygenOS and Pixel Android make the most of the available battery capacity. Poorly optimized software will drain the battery quicker.
  • More RAM (e.g. 8GB vs 6GB) improves battery life by allowing more apps and data to stay in memory rather than reloading constantly from power-hungry storage.

Again, a balanced approach is best. The Pixel 7 Pro demonstrates that flagship-level performance and great battery life aren’t mutually exclusive.
