Table of Contents
1. Best Samsung battery life –Samsung Galaxy S23 Ultra
- The score for battery test: 12:43
- 5,000mAh battery capacity

Top 2023 Smartphones, The Galaxy S23 Ultra’s battery life in actual use is outstanding, even though it didn’t perform as well in the PC Mark battery test as some other phones lower on our list.
For the first time, all models use a Qualcomm processor instead of being limited to Samsung’s own Exynos CPUs, which sometimes have inferior battery life, in places like the UK. Instead, we discovered that the Ultra lasted far into the second day even with the (great) display set to its top WQHD+ resolution and at the adaptive 120Hz rate thanks to the Snapdragon 8 Gen 2’s exceptional performance and battery.
Similar to the iPhone 14 Pro Max which is included in Top 2023 Smartphones, this is the phone to purchase if you want the very best specifications available but don’t want to sacrifice battery life. The Galaxy S23 Plus, which has a flat 6.6-inch screen and a slimmer design and lasts almost as long as the Ultra in everyday usage, is an excellent alternative if you don’t require the S-Pen pen or think the boxy design with a 6.8-inch curved display is too much. It also scored a remarkable 15 hours 47 minutes in our testing.
2. Motorola Moto G82 5G – Great budget pick
- Score on the battery test: 15:15
- 5,000mAh battery capacity

Top 2023 Smartphones, Along with the Redmi phones on our list, the Motorola Moto G82 is another excellent, less expensive phone with a terrific battery life. If you prefer a simplified, stock version of Android to the MIUI skin you will get on the Redmi choices, it’s a good alternative to choose in Top 2023 Smartphones list.
You can obtain a top-notch phone for the money if you don’t mind the rather subpar cameras. It boasts 5G, a big, brilliant OLED screen that’s uncommon in this price range, a quality 120Hz refresh rate to make things seem fluid, and all of these features are combined that’s included in Top 2023 Smartphones.
Top 2023 Smartphones, Although it isn’t a great pick for gaming, overall performance is excellent. Additionally, you may use it for a second full day on a single charge using USB-C.
3. Best gaming phone – Asus ROG Phone 7 Ultimate
- Score on the battery test: 14:55
- 6,000mAh battery capacity

Consider purchasing a phone made expressly for gaming in Top 2023 Smartphones if you want long-lasting battery life for playing mobile games. Although expensive, the Asus ROG Phone 7 Ultimate is your best choice for 2023. It uses two distinct 3,000mAh cells to reach its 6,000mAh battery, which is the biggest on our Top 2023 Smartphones list.
There is a fast charger included, and one of the phone’s two USB-C connections may be used to charge it while it is being used to play games in landscape mode. To keep things cool while you’re draining that large battery with high-end games, there is also a fan attachment provided.
The poor quality of the cameras is a drawback. Although it costs approximately the same, the phone is well below the iPhone 14 Pro Max and Samsung Galaxy S23 Ultra despite having a primary sensor that performs satisfactorily in the daytime. However, if you’re looking for a Top 2023 Smartphones and don’t mind a large, hefty smartphone, you’ll be rewarded with astounding performance and incredible battery life.
4. Best small phone battery – Zenfone 9
- The score for battery test: 13:37
- 4,300mAh battery capacity

We are surprised by the Asus Zenfone 9’s impressive battery life given that it is a very tiny and flagship-level Top 2023 Smartphones. In our assessment, we discovered that the battery was consistently hanging around 50% after a typical day of use.
Despite the promise of two years of updates, this phone meets all the requirements. Top-notch hardware, excellent cameras, and Asus’s subtle take on Android (i.e., it doesn’t overly alter the look and feel) combine to create a fantastic design.
It somewhat overheats during heavy usage, but if you want to play PUBG, you probably already know that this isn’t the phone for you. Others may find it to be a highly portable phone with a long battery life included inTop 2023 Smartphones.
5. Great premium option – Google Pixel 7 Pro
- The score for battery test: 12:46
- 5,000mAh battery capacity

Although the battery life of the Pixel 7 Pro is the greatest we’ve ever experienced on a Google phone, it’s not quite as impressive as the top iPhone and Samsung options in our list. The Pixel 4’s extremely terrible battery life is a thing of the past.
This is also by far the finest phone Google has ever made. Yes, it’s massive, but that’s how the bigger battery, a gorgeous 6.7-inch 120Hz display, and some of the greatest cameras in the industry could all fit inside. Whether you use powerful primary, ultrawide, or telephoto lenses, this phone is genuinely so much joy to photograph with. It encourages you to take more pictures, which is a hallmark of an excellent camera.
Although the design is a bit controversial and it charges slowly, once it is full, it should last the entirety of the day and then some, even when you’re using it vigorously.
Frequently Asked Questions
How is the size of a battery determined?
The unit of battery capacity is milliamp-hours (mAh). A battery’s technical capacity increases with the mAh value. However, the devices with the greatest mAh don’t necessarily have the longest battery life.
It may depend on how effectively the app works with the phone’s CPU as well as how frequently you use it. Expensive high-end phones frequently feature quicker processors and sharper displays, but larger batteries are needed to make up for these improvements or may have fatal flaws (like the Pixel 4 from Google, which has a famously short lifespan).
What should you be cautious of?
It’s crucial to think about your intended usage for the phone as well as the hardware it offers when selecting a phone. When compared to a phone with a similar-sized battery but a smaller or lower resolution panel, for instance, durability will be significantly impacted if you choose a larger-screened phone.
Some phones, especially those in the mid-range and budget ranges, may have huge batteries and excellent battery life yet lack or have slow fast-charging capabilities, making it difficult to recharge them at times other than overnight.
