Acer Predator Helios Neo 16 Battery Died Right After Warranty Ended – Coincidence?

It's interesting how some things seem to happen at just the right time. I purchased an Acer Predator Helios Neo 16 (i7 HX 13th Gen, RTX 4060, 16GB RAM) in October 2023, and it performed well—until recently. Right after the warranty expired, the battery health took a dramatic turn, leaving the laptop barely usable without being plugged in.

Original Battery Capacity: 90,614 mWh
Current Full Charge Capacity: 8,978 mWh (a fraction of what it once was)
Cycle Count: 165 (not exactly excessive use)

Attached are battery reports and a timelapse video showing just how quickly the battery drains. A premium gaming laptop should last longer, but it seems like this is not an isolated

incident.

Strange how these things tend to happen just when support is no longer an option. Would be great if reliability extended beyond the warranty period. Has anyone else experienced this? How did you handle it?

Not seen that happening before and I have the PHN16-71, post the complete battery report, I suspect something else is amiss: Open the battery report with your Edge browser, press Ctrl+P or right click and select "Print to Microsoft PDF", attach the report to your reply, type @Puraw or use "Quote" when you reply so I will get an alert. You should not disconnect the power adapter but leave the battery charged 100% at all times, this system will lock Predator Sense once the battery <40%. My estimate is that you will get 30 minutes battery backup with a new battery while playing games and the power adapter is disconnected. Are you perhaps using Acer Care and Acer Sense "Battery Calibration", "Optimization" or "Battery 80% charge limiting"? even when uninstalled these services keep running. I don't see 100% charged, are you using a USB-C charger?

Thanks for your response.

@Puraw

I’ve been very careful with my battery usage:

I always kept the charging limit at 80% for better battery health.
I never used a USB-C charger.
I frequently kept my charger plugged in to avoid unnecessary cycles and to focus on my work without interruptions.
I used Acer Care Center and Predator Sense for monitoring and optimization.

Despite all this, my battery health dropped from ~90,000 mWh to less than 9,000 mWh overnight. This is not normal. My cycle count is only 165, which isn’t excessive.

I’ve attached my complete battery report (PDF) as requested. Let me know what you think. Could this be a firmware issue? Or am I just expected to replace the battery so soon?

Hi, you are doing everything wrong with your battery, you should never limit the charging to 80%, stop the battery monitoring and battery "Optimizing" nonsense (a myth) and you should disable accSvc in Windows Services. Always leave the power adapter plugged in 24/7. That battery has not been registered in the new BIOS version 1.18 and by MSACPI. Boot to BIOS with F2 and press F9 (reset) and F10 (Save changes). Boot to Windows and in Device Manager uninstall the 2 battery drivers on the picture below. Just reboot and disable Fast Startup and Hibernate in "Change what closing the lid does" and "Change settings currently unavailable" and reset the Power plan in "Reset Power Plan", reboot and perform the mandatory Full Charge Cycle:
Charge the battery to 100%, check that the battery meter on the taskbar reads 100% and wait an extra 5 minutes, unplug the power adapter and work till the system shuts down automatically, do not touch the power button just close the lid. Plug in the power adapter and charge till the amber battery LED turns blue and wait 5 minutes, open the lid and boot to Windows, that's it.

If you kept your PHN16-7x whichever model you have plugged into the adapter 24/7 then there is NO way that your battery would be so depleted unless its a faulty battery., as having 8978mWh power left of a battery that has a design capacity of 90,674mWh there must be something going on with such a new high end Acer laptop

This is the same exact battery that you have in my PHN16-71 model laptop, this laptop is 3 months old and its Full Charge is even better than its Design Charge and only has 19 Cycles Counts, my laptop is always plugged in 24/7 but once a month I let the battery discharge overnight and then recharge it at 20% power. I know that its not 12 months old but your battery should not be so depleted after 12months as these batteries should last at least 3-4 years before you need to replace them. Get a technician to check your laptops main power rail and its charging rail if they are operating 100%, Good luck.

These are the batteries that both the PHN16-71 and 72 models use, so buy a genuine Acer new battery to replace the old battery'

A week ago, I turned on the "Optimized Battery Charging" setting in the PredatorSense app and last night right after unplugging my adapter, my laptop died in 2 mins. When I plug in the power adapter, it says 98% charging but won't last a minute after unplugging. So I turned off the Optimized Battery Charging setting and set it to Full Battery Charging again.

I have checked the powercfg/batteryreport and it's saying that I've lost tens of Wh of battery in the past week. I'm attaching the battery report here. I've tried everything. Reset the BIOS, uninstalled and reinstalled the battery drivers in the Device Manager, reset the power plans in the Control Panel and also calibration in the PredatorSense app. Please help!! I think it's a software thing that's bricking my laptop's battery.
