For many smartphone users, battery life is the ultimate deal breaker. No matter how sleek a phone looks or how sharp its camera is, if the battery cannot last through the day, frustration quickly sets in.
That’s where smartphones with 8000mAh batteries step in. While most mainstream flagships stick to cells between 4500mAh and 6000mAh, a few brands are pushing boundaries with 8000mAh monsters designed to last not just hours, but multiple days on a single charge.
If you want a phone that prioritises endurance, here are five standout devices with 8000mAh battery capacity.
1. Honour Power 5G
The Honour Power 5G breaks the stereotype that big batteries mean bulky phones. At just 7.98mm slim, it packs an 8000mAh battery alongside 66W fast charging, a bright 6.78-inch AMOLED screen, and the Snapdragon 7 Gen 3 processor.
It proves that you don’t have to sacrifice design or performance to enjoy multi-day battery life.
2. Oukitel WP10 5G
For the adventurous, the Oukitel WP10 5G is practically a survival tool. Rugged, waterproof, and shockproof, this phone was built for outdoor explorers and field workers.
Its 8000mAh battery lasts for several days, even with 5G connectivity enabled, making it a reliable companion whether you’re hiking, camping, or working in harsh environments.
3. Oukitel WP5
The Oukitel WP5 offers the same 8000mAh capacity but in a smaller frame with a 5.5-inch screen. This makes it more compact while still being extremely reliable.
It’s a favourite among workers in construction, logistics, and outdoor industries who value stamina and durability above all else.
4. Oukitel B2021
Not every rugged phone has to look like a brick. The Oukitel B2021 blends everyday usability with durability, offering a 5.86-inch HD+ display, 6GB RAM, and expandable storage.
With its 8000mAh battery, this phone ensures you’ll almost forget what it feels like to carry a power bank.
5. Blackview BL8000
The Blackview BL8000 goes beyond with an even larger 8800mAh battery for unmatched endurance. It supports 33W fast charging, is certified with IP68/IP69K and MIL-STD-810H for rugged reliability, and features a 6.78-inch 120Hz display with plenty of storage and RAM.
While it’s on the bulkier side, it’s the perfect pick for users who need maximum durability and multi-day battery life.
