SF314-57G-716Z sudden battery capacity drop

swft3

Hello,

I have just found out that my laptop's (Swift 3) battery capacity has dropped dramatically in recent weeks, it is so bad that it only has 30 minutes of battery life left without plugging in now. I searched through the community and came across generating a Battery report for my own laptop.

From the results, it is shown that the capacity has dropped from around 20000mWh in August to only 7503mWh left in late September. The speed of battery degradation is appalling.

Then I noticed something more interesting. The Battery report has stated that I had a session of connected standby for 592 thousand hours in August -- which is 67.6 years in conversion. It is genuinely impossible for that to happen.

The coincidence of the timeline between the probably charging time error and the sudden battery capacity drop has made me curious if the battery is really damaged or is a bug from Acer's battery program. I also would like to know if there's any way to fix this problem.

Thank you!

Sorry. Actually has been degrading pretty fast since April. Probably an internal cell short. Should be replaced. Arrange for warranty repair If it's less than a year old. If no longer under warranty, google search SF314-57G & battery for vendors who ship to your location. About $50usd. Acer doesn't make batteries but may relabel those made by battery manufacturers like LGC, Murata, Panasonic or Lite-On

You can also do the battery reset and battery calibration routines, just in case the numbers are all just bogus. Most of the Swift 3 models have abattery reset pinhole on the bottom of the unit. Power the system down and disconnect everything, including the charger. Using something like a bent paperclip press and hold that reset button for 15-30 seconds, release and wait 15-30 minutes and plug only the charger back in. Wait for the full battery indication before turning things back on. Next, in Windows, run on battery until it shuts down automatically due to low battery. Leave it off and plug the charge back in until it shows full battery. Do that a few times in a row then check to see what the stats have changed to. If it was just corrupted data it will go back to normal, if it's the battery itself then it's definitely time to change it.
