Nitro V 16 ANV16-41 battery draining plugged in with 230-watts adapter

I have a Nitro V 16 ANV16-41 and I struggle with battery draining when gaming and plugged in. I read in this thread (https://community.acer.com/en/discussion/711390/acer-nitro-v-16-battery-draining-while-plugged-in) that it was because the original adapter (135W) is not enough for the consumption when gaming.

So I bought a 230W adapter, but I still have battery draining. I don't know what to do. I can't play more than 3 hours before Nitrosense change to Eco Mode. What should I do to prevent the draining? I'm considering retuning it before reaching my 30-days 😔

Having the same problem on 135w. How is this even possible? BIOS is up to date, drivers too. Super weird

Hi guys, im from Italy so forgive me if I say smt wrong.

I spoke to Acer and they said to me that battery draining is normal, the GPU and CPU are so powerful and they ask for more power than the adapter can get. He said to me that it’s designed like that, and it’s designed to never stop, even if you play for 5-6 hours. I’ve never tried to do so, my eyes burn after a hour or two and I need to rest, but someone can try. They even said I needed to upgrade the BIOS but even after that nothing happens. If the pc doesn’t run out of battery, we could just ignore the battery perc, but if the pc turns off…well that could be a biiiiiig problem.

Hi everyone, I have the some problem like you guys. I did not buy the 230w adapter, bcs I saw that this adapter is not compatible with this device, so I am still using the 135w adapter what I got with my laptop. Have the same issue, playing on the Turbo mode for 2-3hours and dropping the battery to the 30%, then the mode is automatically switched to the eco/balanced and instantly dropping the FPS in the game, etc.. it is charging back to the 40% and again dropping to the 30%. I wrote with the Czech support and they told me that it is normal for the gaming laptop, but it should not be. I have a gaming lenovo legion before and it was without any problems. So, it should be fine if there will be someone from the Acer who will help us or they will give us some software update - if it is help us, i dont know (or compatible charger) or something what will solve this issue, bcs we cant gaming longer then 2-3hours in the turbo mode.

Hi,

I believe this is expected behavior and by design:

Modern laptops use an IC called Hybrid Power Boost (HPB) Charge Controller (aka buck-boost DC-DC). It allows battery work (discharge energy) with the adapter to supply the system load when it exceeds the power level capability.

This helps the system to provide a constant output voltage, and minimizes the overloading of the input power source when the CPU and dGPU are in Turbo Boost mode.

Some of these components can be programmed via the SMBus interface. So, there's no point in using a higher power supply if the motherboard manufacturer has set a limit on the input current (A).

Perhaps a firmware update could improve this behavior, currently the latest version available for the Nitro V16 ANV16-41 is 1.12:

Hi eGomes, thanks for your answer. I downloaded the latest bios update, which is 1.12. Nothing changed. I was doing some testing and I recognized that i started to drop my battery during the balanced mode, in power mode and also in turbo mode. Only Eco mod is only one where I am not dropping my % of the battery during the gaming, but I am still playing on Eco, so I am playing on 40-50fps. How can i solve it, if nothing helps? So i bought this laptop to play only 2-3 hours and then i will have to wait 1hour then the battery will be full and to start gaming again?

Hi, it was 16 days without any response here. Problem is still the same. My battery is draining in balanced mode, what i can do with that? Cant play any game on gaming laptop, because the battery is instantly draining. I will understand this issue in the Turbo mode, but not in the balanced or performance mode. Cant play anything on that without battery draining, so maximum 2-3 hours playing.

Depends on your charger and game power utilization. If you have a 135W charger the drain will be more and if you have a 180W charger it would be less - just an example. Some chargers supply less power than what laptop uses when utilized at peak levels and so battery power too gets consumed to compensate for the shortfall.

After more than 5 months since this message, and as a TL;DR:

The battery draining it's "by design" (Hybrid Power NOS).
Upgrading the adapter to the max (230W) will improve the time until full draining, but the problem will persist.
Until now, Acer have not recognized nor released an update to fix it.

The best decision was returning it and buying another brand. I can use it at max power (i7, RTX 4070, 200W adapter), and no draining. I'm sorry for the ones who can't return it 😓 Maybe @Puraw can help us report this to Acer.

Hello everyone, as eGomes said, you can contact Acer.

Use this URL too ( https://uk.answers.acer.com/app/ask ) to send the email in which you all may report this problem. I already did, if everyone here reports the problem, maybe we'll have a chance to get this fixed.
