Star Yue L's power loss is fake. Low-current electrical appliances consume power: As long as the is connected to the vehicle, many electrical appliances continue to consume power, albeit with a very small current. The power consumption is minimal and can last for many days. Therefore, if the vehicle is not driven for an extended period, it is recommended to disconnect the negative terminal of the battery. The battery's capacity diminishes with use: Even if the battery is not connected to any electrical appliances, it will naturally lose some charge over time. If the car remains unused for a long time, the battery cannot recharge, and starting the engine requires a significant amount of power, making it prone to power loss. Each instance of power loss significantly reduces the battery's performance. Battery discharge has a cliff effect: New batteries discharge in a relatively linear curve, whereas older batteries with significantly degraded performance may appear to have a full charge based on indicators, but their power can suddenly drop to zero at a certain level.

















I've been driving the Xingyue L for a while and have indeed encountered drain issues, especially when leaving it parked for a few days in winter—the battery would alarm and fail to start. Friends with the same car have reported similar issues, so it seems it's not entirely a rumor. The reasons could be high power consumption from electronic devices like the navigation or remote control modules, or the battery itself aging. It was fine when the car was new, but over time, the battery capacity decreases. It's advisable to develop a habit of regularly checking the voltage and driving the car at least half an hour each week to charge the battery. Avoid installing too many additional devices to prevent overloading the system. Always turn off all lights and the AC when parking to avoid long-term inactivity. If problems arise, you can call for roadside assistance or visit a repair shop to check the circuits and replace the battery. It's not a major issue, but it should be addressed promptly to avoid affecting your driving experience.

Having worked in the auto repair industry for many years, I've encountered numerous cases of drain in the Xingyue L, and not all of them are fake. Common causes include control units failing to enter sleep mode leading to continuous power consumption, or issues like short circuits and fuse problems. Owners can perform simple diagnostics themselves: measure the battery voltage the next day after parking; if it's below 12.6V, there's an issue. It could also be due to excessive power consumption from aftermarket electronics like dashcams. Preventive measures include regular battery maintenance and cleaning corroded terminals. If battery drain occurs frequently, it's best to visit a 4S shop to scan for fault codes to check if it's an ECU setting issue. This isn't a severe fault, but delaying repairs can damage the battery. Generally, adjusting the system or replacing the battery can solve the problem, and the cost isn't high.

As a tech enthusiast, I've researched the authenticity of the Xingyue L's drain issue. Some reports are valid, with the root cause being insufficient optimization of the Battery Management System (BMS) or software bugs leading to higher-than-expected standby current. Especially during prolonged parking, the system fails to enter deep sleep mode, resulting in excessive current consumption. Upgrading the vehicle software or resetting settings often improves the situation. However, each vehicle's condition varies—environmental temperature and driving habits all play a role; thus, it's hard to generalize the truth. A preventive method is to monitor the current with a multimeter; normal readings should be below 50mA. Regularly drive and charge the car, avoiding idling for over a week. While battery drain isn't uncommon, timely action is key—no need to panic.

I was terrified when my Xingyue L experienced drain just a few months after purchase, thinking the car was broken. Later, I learned this wasn't an isolated case—some owners reported starting difficulties after prolonged parking. Possible causes include new battery quality issues or default settings draining power quickly. The solution is simple: ensure all electronics like headlights or AC are off before locking the car. For long idle periods, start the engine periodically to recharge. If drained, jump-start with help or visit the dealership. Overall, the car performs well, and battery issues can be mitigated with proper habits—no need for excessive worry. Key is regular maintenance; batteries typically have multi-year warranties, so timely replacement suffices.

I've been using the Xingyue L for almost two years now, and drain has happened once or twice. It's a real issue but not a widespread one. The causes vary: colder weather, prolonged parking, or abnormal power consumption by electronic modules. For example, if left unused for a week, the voltage drops significantly. Fortunately, I've learned to prevent it—regularly checking the voltage to keep it above 12V and disconnecting the charger when not in use. Overall, the car is reliable, and most battery drain issues stem from maintenance neglect. I recommend reading the owner's manual to understand the sleep mode settings. When problems arise, don't panic—a simple jump-start followed by an hour of driving to recharge usually resolves it. After developing good driving habits, such issues become rare, making this car quite worry-free.
