AN515-57 loses charge when turned off the battery doesn't hold its charge over time.

Na, didn't work. Still losing charge when it's turned off.

Thanks for trying though I appreciate it.

I've turned all power setting set to: "turn off"

Down to 75% yesterday from a full charge on the 25th.

Think I'll charge it back up and check it every 5 days. To monitor the drop.

All I can think of is the power isn't cut off close to the battery.

Or the battery is crook.

Cheers Bob.

A year, I think. Unfortunately, product registration doesn't log the date I registered it.

It has been doing losing charge since near new. By near, I used it for 20 days while my game pc was being repaired. Last Xmas.

Since then, I power it up every now and then to check it. The battery/software updates just in case I need it.

Then put it in its pillow for a while longer.

When I really noticed the battery, I started it up every month. And every month its down on charge.

While I can accept some leakage it seems excessive.

My 10-year-old HP takes a lot longer. But the battery on it is a removable one.

The Acer really seems to be running something while shut down.

The power meter on it is deficient. The estimated time to fully charge is out.

Not a lot about 15 minutes from 75% to full. Not great deal.

Thats an interesting article brummyfan2 Thanks.

I'll see if I can find the Acer battery calibration system.

Guess I've got a project for tomorrow.😀 Thanks for your help and directions.

Cheers Bob.

Fire it up for the first time since the battery calibration on the 30/12/2022.

8 days ago, down from 100% to 93%. A 7% loss with only 1 startup (this one). I didn't time it, but I suppose roughly 30 seconds power to shut down.

I'll give it some more time and see what the drop is in another 8 days or so.

Cheers Bob.

Puraw, has offered a possible solution.

I've follwed the suggestion. So time will tell.

Cheers Bob.

It is related to Windows11 "S0 Modern Standby" Microsoft's new Sleep Mode protocol that is difficult to control in Power Plan advanced settings, if you see "USB Selective Suspend" in Power Plan advanced settings turn that off: 
Also you may not be fully shutdown but in hibernate mode or hybrid mode if you have Fast Startup enabled, disable both these options. Google this topic it is a common problem for all brand laptops running Windows11.

I've given up. When I go into the shop, I bought it from the salesperson disappears.

So, my only answer is: to never buy Acer again. It's the only laptop I've had battery troubles with. All my HP's the batteries would remain charged for months.

This one is a constant -1% a day.

Possibly/probably, different metal mixes in them. But….

There is another problem with it too. Copying large 100GB +, game files from one usb drive to another can flatten the battery very quickly. Even plugged into the power. A powered hub may help but haven't tried one. I don't do it that often. But worth a mention. Actually, only when getting it ready to play my games. Saving download time by copying their directories from my other pc drives.

I got it because it was labeled as a game laptop. While it could handle games like Witcher 3. It struggled on Horizon Zero Dawn at full spec. Still playable though. So, it did the job mostly.

My condolences on your purchase.

And I hope your fully recovered from your hospital time.

Sorry I'm of no help to you.

Cheers Bob.
