Best phone battery life | Phones with best battery life 2021 – No matter what you are looking for in a smartphone, one thing is certain, you will want to make sure it offers decent and good battery life.
Phones with best battery life 2021
Battery capacity is measured in milliamp-hours (mAh). The higher the mAh of a battery, the higher its technical capacity. But the phones with the highest mAh aren’t always the phones with the best battery life. Here, are the top best phones with best battery life of 2021:
- Doogee S58 Pro – Best overall
- Moto G9 Power – Best for ease of use
- Moto G9 Play – Great value
- Xiaomi Redmi Note 9S – Great all-rounder
- Xiaomi Mi 10T Pro – Most feature-packed
- Vivo X51 – Best camera
- Xiaomi POCO X3 NFC – Best value
- One Plus 8T – Most powerful
- Xiaomi Mi Note 10 – Feature-packed
- Doogee S88 Pro – Biggest battery
Doogee S58 Pro – Best overall
- Battery test score: 14:10 (GB 4), 17:01 (PC Mark)
- Battery size: 5180mAh
A budget offering that specializes in being resilient and long-lasting. The cameras and performance aren’t great but the S58 Pro will still serve those looking for a device that can withstand an active lifestyle and long stints away from the wall plug well.
With some of the best battery longevity that we’ve tested, the S58 Pro is a great option for hikers, divers or people who work in extreme conditions. The one thing no-one can complain about is the battery, which lasts multiple days on a single charge.
Moto G9 Power – Best for ease of use
- Battery test score: 16:18 (PC Mark)
- Battery size: 6000mAh
The latest in a growing line of Moto G phones built specifically to offer exceptional battery longevity, the Moto G9 Power packs in a whopping 6000mAh cell, which offers up enough juice for multiple days usage at a time.
It also sports a pleasing display and a water-repellent design, and while its cameras are on the underwhelming side, if they’re not your top priority, there’s a lot going for the Moto G9 Power.
Moto G9 Play – Great value
- Battery test score: 16:04 (PC Mark)
- Battery size: 5000mAh
An even more affordable alternative to the G9 Power is Motorola’s own G9 Play. While it doesn’t pack in quite as sizeable a cell, the phone still delivers on battery life.
If you’re not hankering after super-fast 5G mobile speeds, the Play is a great affordable option with a big screen and a huge battery.
The display needs work, as does the camera, but for the price and paired with Motorola’s slick user experience, the G9 Play isn’t a bad budget offering by any means.
Xiaomi Redmi Note 9S – Great all-rounder
Battery test score: 15:03 (GB 4)
Battery size: 5020mAh
The Redmi Note 9S’ key selling point is its 5020mAh battery. With some budget- to mid-range hardware inside, along with a large (6.67in) – but only Full-HD+ – screen and the Snapdragon 720G processor, it was able to put in the longest result we’ve ever seen in the Geekbench 4 battery life test.
Though its battery life excels, this remains a budget phone, so you won’t find support for wireless charging. It is otherwise a great all-rounder at this price.
Wired charging is fast – at 18W over USB-C – and a 22.5W charger is supplied in the box, which enabled us to get from 0 – 36% in 30 minutes.
Xiaomi Mi 10T Pro – Most feature-packed
- Battery test score: 14:24 (GB 4), 14:55 (PC Mark)
- Battery size: 5000mAh
Dubbed a ‘spec beast’ in our review, the Xiaomi Mi 10T Pro packs in flagship-class innards against a mid-range price tag.
What’s more, it features a huge 5000mAh battery that translates to days worth of use per charge and has no right being the final punctuation in a long list of hardware highlights.
If the battery alone isn’t enough to tempt you, the 144Hz display, 108MP camera and the 5G connectivity should win you over.
Best phone battery life | Vivo X51 – Best camera
- Battery test score: 14:42 (PC Mark)
- Battery size: 4315mAh
Vivo’s first true offering in Western markets comes in the form of the Vivo X51 and it’s a great first gambit – even if it’s essentially just a re-branded take on the existing X50 Pro.
Its primary hook is a gimbal-stabilised main camera and a competent 5G-capable Snapdragon 765G chipset. A killer design and some top-notch battery life don’t hurt either.
Xiaomi POCO X3 NFC – Best value
- Battery test score: 14:24 (PC Mark)
- Battery size: 5160mAh
One of our favourite budget phones of 2020 also happens to be a superb battery champ, thanks to a large cell, efficient internals and 33W fast charging.
The version we reviewed features NFC but if you pick the Poco X3 up without this extra connectivity, the internal space is instead filled up by an even larger 6000mAh cell.
In testing, that 33W fast charging resulted in 59% charge after just 30 minutes.
Best phone battery life | OnePlus 8T – Most powerful
- Battery test score: 13:24 (GB 4)
- Battery size: 4500mAh
OnePlus’ last flagship of 2020 brings the heat with its 4500mAh battery, which delivers exceptional battery life but not only that, also includes rapid 65W fast charging, resulting in a full charge in just 39 minutes flat.
The inclusion of a 120Hz AMOLED display, Snapdragon 865+ chip and the latest Oxygen OS user experience make this an easy phone to recommend for those looking for an affordable flagship.
Xiaomi Mi Note 10 – Feature-packed
- Battery test score: 13:13 (GB 4)
- Battery size: 5260mAh
The Mi Note 10 is a great phone for many reasons and battery life is certainly one of them. You’ll also benefit from 30W wired charging which gets you to 80% in 40 minutes and fully charged in just over an hour. Impressive stuff.
Doogee S88 Pro – Biggest battery
- Battery test score: No score
- Battery size: 10,000mAh
The Doogee S88 Pro’s 10,000mAh battery is almost unheard of in a smartphone and double many of the other entries in this chart.
In fact, it lasted too long for us to effectively benchmark. Nonetheless, from typical everyday usage, we were able to get a ridiculous six and a half days on a single charge.
There’s also 24W fast charging via the adapter included in the box and even 5W reverse wireless charging. Its rugged design and significant weight (372g) might put some people off, but for people who spend long periods away from the charger, this is a great option.
Battery capacity is measured in milliamp-hours (mAh). The higher the mAh of a battery, the higher its technical capacity. But the phones with the highest mAh aren’t always the phones with the best battery life.
It can depend on how efficient the phone’s processor is in conjunction with the software, as well as how much you actually use your phone. Expensive high-end phones often are faster and have better screens, but require larger batteries to compensate or suffer from crippling shortfalls (such as with Google’s Pixel 4).
