Compatibility Note: Fits iQOO 11S (V2304A) only. This battery uses a dual-cell design (7.78V) — please confirm your original battery voltage before ordering. For reference, Taiwanese retailers sell this battery for $45-53, and iQOO official battery replacement costs 129-200 RMB ($18-28) on promotion. Professional installation is recommended as the phone has a sealed design. Always check your original battery model before purchasing — BA01 printed on your existing battery.

Charging Instructions: Use only a charger designed for 2S (7.4V-7.78V) Li-Po batteries with FlashCharge compatibility. The iQOO 11S supports 200W fast charging with the original charger. Recommended charge current: 2.35A (1C). Never leave the battery unattended while charging. Do not discharge below 6.0V (3.0V per cell).

Battery Care Tips: Avoid full discharge — keep battery level above 20%. Do not expose to high temperatures or direct sunlight. New batteries require 3-5 full charge cycles to reach optimal capacity.

Frequently Asked Questions

The BA01 battery is compatible with iQOO 11S (model V2304A). The iQOO 11S was released in July 2023 featuring a 6.78-inch 144Hz AMOLED display and supports 200W FlashCharge fast charging. If your iQOO 11S battery drains quickly or won't hold a charge, this is the correct replacement. For reference, Taiwanese retailers sell this battery for $45-53, and iQOO official battery replacement costs 129-200 RMB ($18-28) during promotions. Please verify your device model in Settings > About Phone before purchasing.

The BA01 battery has a total capacity of 4700mAh (typical) and a rated voltage of 7.78V. This is because iQOO 11S uses a dual-cell series design (2S) — two cells connected in series inside a single battery pack, producing 7.78V total. Full charge voltage is 8.9V (4.45V per cell). The battery supports the original 200W FlashCharge fast charging capability of the iQOO 11S. Some retailers list the single-cell capacity as 2350mAh, while the typical total capacity is 4700mAh.

Professional installation is strongly recommended. The iQOO 11S has a sealed design with strong adhesive. Replacing the battery requires heating to soften adhesive and careful prying to avoid damaging the AMOLED display. If you choose to DIY, watch a full teardown tutorial before starting, use a heat gun at low temperature (no more than 70°C), and never reuse a battery after removal. Third-party repair shops typically charge $15-30 for labor. iQOO official service charges 129-200 RMB ($18-28) for battery replacement during promotions.
