Bring your Hisense U50 4G back to reliable daily performance with this LPN440400 4030mAh replacement battery. Hisense is primarily known as a TV and appliance manufacturer, but the company has produced a line of budget Android phones primarily distributed in the Chinese domestic market. The Hisense U50 4G (model HLTE222E) is an entry-level 4G smartphone designed for users who need basic calling, messaging, web browsing, and light app functionality — making it a popular choice as a secondary work phone, a device for seniors and children, or a backup phone. The 4030mAh battery was the standout feature of this model, offering several days of standby time on a single charge. This Li-ion Polymer replacement battery restores the full 4030mAh capacity, giving you back the dependable long-lasting power that made the U50 4G a practical budget option. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Why Hisense U50 4G Users Need a Reliable Battery — And How to Spot Degradation: The Hisense U50 4G occupies a specific niche in the smartphone market. Unlike flagship devices that get replaced every 2 years, U50 4G owners tend to keep their phones longer — as a dedicated work phone, a device for elderly family members who need something simple, or as a backup when primary phones are being repaired. After 3-4 years of use, the original LPN440400 battery will have lost significant capacity. Common signs that your battery needs replacement include: the phone no longer lasting a full day on a single charge (originally it could go 1.5-2 days), needing to charge by early evening, the battery percentage dropping rapidly from 30% to shutdown, the phone powering off when opening the camera or other power-intensive apps, or the device taking noticeably longer to charge fully. The U50 4G’s 6.5-inch display and basic processor are not power-hungry, so poor battery life almost always points to an aging battery rather than software issues. Replacing the LPN440400 battery is far more economical than buying a new phone — especially for users who only need basic 4G functionality and appreciate the simplicity and affordability the Hisense U50 provides. Unlike newer phones with sealed batteries that require professional tools, the U50 4G may have a user-removable back cover, making DIY replacement more accessible.
Compatibility Note: Fits Hisense U50 4G (HLTE222E) only. Please confirm your battery model before ordering — LPN440400 is printed on your original battery. This battery is NOT compatible with Hisense U30, Hisense U40, Hisense Infinity series, Hisense A5 (e-ink phone), or other Hisense models. The U50 4G uses a 3.85V rated voltage with 4.4V charge limit — using a battery with different voltage specifications may cause charging issues or inaccurate battery percentage reporting. Always verify your battery model before purchasing.
