🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Restore the gaming performance of your Lenovo Legion 2 Pro with this BL316 or BL318 replacement battery. The Legion 2 Pro is a unique dual-battery gaming phone — it uses two separate batteries (BL316 and BL318) working in parallel to deliver sustained power for long gaming sessions. Unlike standard phones, the Legion 2 Pro has a 6.92-inch 144Hz AMOLED display, dual USB-C ports, and a built-in ATA cooling fan. This listing allows you to purchase either BL316 or BL318 individually — simply select the correct model from the dropdown above.
Understanding the Dual-Battery System: The Lenovo Legion 2 Pro’s dual-battery design (BL316 + BL318) provides several advantages for mobile gamers. First, it allows 90W wired fast charging through either USB-C port — significantly faster than most phones. Second, the parallel configuration reduces heat generation because each battery shares the current draw. Third, it enables “pass-through” charging: you can plug in a charger and play demanding games (Genshin Impact, Call of Duty Mobile, PUBG) without draining the batteries. This replacement BL316 or BL318 battery is built with grade A Li-Polymer cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
Which Battery Does Your Legion 2 Pro Need? The Legion 2 Pro contains two physically distinct batteries installed in different locations inside the phone. The BL316 and BL318 are not interchangeable — they have different dimensions, connector orientations, and cable lengths. Before purchasing, you MUST check which battery is failing:

  • BL316 — typically located on the left side (when looking at the phone’s back with the top up)
  • BL318 — typically located on the right side, near the cooling fan assembly

To identify the correct model, open your Legion 2 Pro’s back panel (requires heating to soften adhesive) and read the printed label on each battery. If both batteries are aging or showing reduced capacity, we strongly recommend replacing both BL316 and BL318 at the same time for balanced performance.
Compatibility & Installation Note: Fits Lenovo Legion 2 Pro L70081 only — not compatible with Legion Phone Duel, Legion 1 Pro, Legion Y90, or any non-Legion devices. The Legion 2 Pro’s internal layout is complex due to the ATA cooling fan and dual USB-C boards. Professional installation is highly recommended. If you choose to DIY, follow these steps: 1) Power off completely. 2) Heat the back panel (use a heat gun at ≤70°C) to soften adhesive. 3) Remove the midframe screws carefully — the fan assembly is delicate. 4) Disconnect both batteries before removing either. 5) Replace the faulty BL316 or BL318, then reassemble. After battery replacement, perform one full discharge-recharge cycle to recalibrate the dual-battery management system.
Battery Care for Gaming Phones: For maximum lifespan of your new BL316 or BL318 battery: avoid full discharge — keep charge level above 20% during gaming sessions. Do not leave the Legion 2 Pro charging while playing heavy games for extended periods — the combination of charging heat and processor heat accelerates battery degradation. Use a standard 5V/3A or 5V/2A charger for everyday charging; reserve 90W fast charging for when you actually need it. If you notice swelling, overheating, or sudden capacity drop on either battery, stop use immediately and replace both batteries. For long-term storage (more than 1 month), keep both batteries at approximately 60% charge.

  1. S**** (verified owner) –

    Bought this BL316 to replace the worn-out battery in my Legion 2 Pro. The phone is back to its original battery life, easily lasting through a full day of heavy use. It arrived well-packaged and was a perfect fit. Shipping to Brazil took about 5 weeks, which is expected for international delivery.

Frequently Asked Questions

The Lenovo Legion 2 Pro uses a unique dual-battery design with two separate batteries: BL316 and BL318. These are NOT interchangeable — they have different physical dimensions, connector positions, and cable lengths. For BL316 battery replacement for Lenovo Legion 2 Pro, you need to identify which side has failed. The BL316 is typically located on the left side of the phone (when looking at the back with the top up), while the BL318 is on the right side near the ATA cooling fan assembly. To determine which Lenovo Legion 2 Pro battery replacement you need: 1) Heat the back panel to soften adhesive, 2) Remove the midframe screws carefully, 3) Read the printed label on each battery — it will clearly state "BL316" or "BL318". If both batteries are aging (reduced capacity, shorter gaming time, or the phone shutting down under load), we strongly recommend replacing both BL316 and BL318 at the same time. This listing allows you to purchase BL316 or BL318 individually — please select the correct model for your needs. For L70081 battery replacement guide, many repair communities have detailed teardown videos showing the exact locations of both batteries.

With a new BL316 or BL318 2750mAh battery (note: the Legion 2 Pro runs both batteries in parallel, so total capacity is 5500mAh), you can expect approximately 5-7 hours of continuous gaming depending on the title. For Lenovo Legion 2 Pro 2750mAh battery performance, light emulation (PS1, NDS) or casual games can reach 7+ hours. For demanding titles like Genshin Impact, Call of Duty Mobile, or PUBG at 90-144Hz refresh rate, expect 4.5-6 hours of gameplay. The dual-battery design also supports Lenovo Legion 2 Pro 90W fast charging — with a new BL316 or BL318 replacement, the phone can charge from 0 to 50% in approximately 12 minutes and to 100% in about 35 minutes (using both USB-C ports simultaneously). For optimal BL316 BL318 battery life for gaming phones, avoid charging while playing heavy games for extended periods — the combined heat accelerates degradation. To maximize longevity, use a standard 5V/3A charger for everyday charging and reserve 90W fast charging for when you need a quick top-up before gaming sessions.

Professional Lenovo Legion 2 Pro battery installation is strongly recommended for BL316 or BL318 replacement. The Legion 2 Pro has a complex internal design due to its dual-battery architecture, ATA cooling fan, dual USB-C boards, and extensive adhesive sealing. To replace BL316 battery in Legion 2 Pro L70081, the phone requires: heating the back panel (60-70°C) to soften strong adhesive, careful removal of multiple midframe screws, disconnecting both batteries before removing either (to avoid short circuits), and precise handling of the delicate fan connector. For DIY Lenovo Legion 2 Pro battery replacement, watch a full teardown tutorial before starting — the fan ribbon cable is particularly fragile. Use a heat gun at low temperature, never use a metal tool to pry the battery (use plastic spudgers), and label each connector. If you only replace one battery (BL316 or BL318) and not both, ensure the existing other battery is in good condition — mismatched battery ages can cause uneven charging and reduced overall capacity. Third-party repair shops typically charge $30-50 for labor on dual-battery gaming phones. Lenovo official battery replacement costs vary by region, typically $25-40 per battery plus labor. For L70081 battery replacement guide, many YouTube tutorials show step-by-step disassembly — search for "Legion 2 Pro battery replacement" and pause frequently.
