My Honest Opinion
For business users who prioritize battery life and raw performance over brand prestige, this phone is a solid choice. The specs are on paper, but the lack of a well-known might give some pause regarding updates and support.
The LOJSMA I26 Ultra is a beast of a business phone, built for those who need maximum uptime and power. The 700mAh battery is its standout feature, easily powering through a full day of heavy use with conference calls, emails, and document editing, often lasting into a second day. The Snapdragon 8 Gen 4 chipset, paired with 12GB of RAM, ensures that even the most demanding business apps run without a hitch, and the 512GB of internal storage provides ample space for files, presentations, and media.
However, the phone's sheer size is a double-edged sword. The 6.99-inch screen is fantastic for viewing spreadsheets and documents, but it makes the device difficult to handle with one hand and it won't fit comfortably in smaller pockets. The included stylus pen is a nice touch note-taking and precise edits, and the face unlock works reliably. While the build feels solid, the LOJSMA brand relatively unknown, which raises questions about the frequency and longevity of Android 15 updates compared to major manufacturers.
