Pixel 7, Samsung S23 & iPhone 14: Which one has the Best Battery Life

October 19, 2022

No more charging your phone once a week. As phones become more advanced and powerful, the battery life becomes shorter. This is the price we all have to pay today.

Still, having a mini-computer in your pocket surely beats the phones of 15 years ago. And in today's smartphone market, three names have reached new heights, and those are Apple, Samsung, and Google.

How do the three flagship models compare when it comes to battery life? Letā€™s find out.

Apple iPhone 14

Historically, iPhones have not been phones with a large battery capacity and, therefore, enviable autonomy. In fact, the battery has been one of the strongest points of criticism of these, although this does not mean that it has been bad. It's just that in this sense they have been below what most Android phones offer.

With the iPhone 14, this changed for the better, at least a bit. As is the tradition, Apple deliberately left out some details at the presentation of the iPhone 14 series. At the presentation of this series, Apple stated that the iPhone 14 series offers "all-day battery life", and for the iPhone 14 Plus, they stated that this is the iPhone that will have the best battery life for an iPhone so far.

The details about the batteries of the iPhone 14 model came through the Chinese regulatory database. Thus, the battery capacities of the iPhone 14 series are as follows:

  • iPhone 14: 3,279 mAh

  • iPhone 14 Plus: 4,325 mAh

  • iPhone 14 Pro: 3,200 mAh

  • iPhone 14 Pro Max: 4,323 mAh

By comparison, the iPhone 13 mini has a 2,406 mAh battery, the iPhone 13 has a 3,227 mAh battery, the iPhone 13 Pro has a 3,095 mAh battery, and the iPhone 13 Pro Max has a 4,352 mAh battery.

So, the iPhone 14 arrives with a slightly larger battery capacity compared to its predecessor. The iPhone 14 Pro brings a slightly bigger improvement compared to its predecessor, while the iPhone 14 Pro Max has a slightly smaller battery than its predecessor. iPhone 14 Plus has the largest battery, and will almost certainly offer the best autonomy of all iPhone 14 models.

Google Pixel 7

Google did a great job when making a compact flagship out of the Pixel 7. When talking about battery life, here too it does a good job as the 4,355 mAh allows the Google Pixel 7 to stay a day and a half away from the socket even with somewhat intense use. This autonomy falls with the most intense use, such as games, without going strong for the full day, at least as a general rule. A super-saving mode can boost these numbers to 72 hours!

But if you use bulky apps and games that require high performance, then you should probably get around 7-8 hours of screen time. This means that if your battery drains faster than this, then there must be a problem and you should follow Googleā€™s troubleshooting methods to improve battery life on this phone.

For wired charge times, these are the percentages with an 18W charger:

  • 5 minutes of charging: 8% battery.

  • 10 minutes of charging: 16% battery.

  • 20 minutes of charging: 32% battery.

  • 30 minutes of charging: 48% battery.

  • 50 minutes of charging: 74% battery.

  • Total: 1 hour and 45 minutes.

The battery issue is common among most Android devices. After a couple of years of use, the battery degrades and its lifespan is reduced. But in the case of Pixel smartphones, things are different because they come with strong algorithms that prevent battery life degradation.

Samsung S23

This phone is about to come out and the information regarding battery life is still uncertain. Be that as it may, there are two main rumors ā€“ one is that the battery will be smaller due to compactness, and the other is that the battery will be more powerful than what the S22 has.

Letā€™s remember, the Galaxy S22 mounts a 3,700 mAh battery that, with moderate use, has given us between 4 and a half hours and 5 hours of screen time. This means that you can get to the end of the day if you only use your mobile to check email sporadically, some instant messaging, some navigation, and, of course, your fantastic photos.

If you are going to use it to take non-stop photos or videos, play games, or spend hours jumping from reel to reel on Instagram or TikTok, it is more than likely that in the middle of the day you will need a visit to the charger.

Unfortunately, Samsung has lagged behind by offering just 25W fast charging that will take 28 minutes to reach 50% and 67 minutes to complete 100% charge. It does have wireless charging, but that doesn't improve it as it only supports 15W power.

Now, back to the S23 - the battery life of the Galaxy S23 series is expected to increase due to the use of a new Snapdragon 8 Gen 2 processor made with 3nm technology, as well as the new generations of OLED panels that they may bring to the table. However, if Samsung goes for a complete redesign and waterfall display on the S23 series, the battery sizes of the S23, S23+, and S23 Ultra may need to be downsized and their capacity reduced, which will make up for more frugal hardware to get there.

In our opinion, if the new chipset requires more juice, the battery capacity will be greater. If Samsung manages to improve the processing power battery requirements (meaning that the phone will use less battery to operate), then the smaller battery can be implemented. Either way, it seems that the S23 will have a battery life quite similar to the one the S22 has.

Final Verdict

So which phone has the best battery life?

- On top comes the Pixel 7, which is quite understandable since itā€™s the ā€œweakestā€ of the three, hence will use less battery to operate. Plus, the new chipset works perfectly to save some battery.

- The second place is reserved for Samsung S23, which will have more or less the same battery life as its predecessor, which is still quite good.

- Finally, even though Apple did a good job of boosting the battery life for the iPhone 14 a bit, it still lags behind the three, although not far away from Samsung phones.
