original battery and charger.
Just got is used
it charger normally at first but around 30 percent it really slows down and then suddenly shoots up to 90 %s.
I let it drain to 0 % but the issues persists
Can i somehow force this laptop to charge fast, like normally?
voltage is fine. up to 8v
wear level 30%
10 000 - 20 000 mW charge rate. but the actual capacity goes up by 20s and 10s like - 40637 mW to 40652 mW and so on.
Device - Dell 7v69y53 original e5570 battery
watched a video for an hour. max brightness, highest performance. went down to 62 or something and then in an instant it went down to 6 percent with battery low warning. didn't connect the charger. soon it hibernated, opened dell bios. for an hour it has been on, screen is on and i am in the bios. it has been saying 1 percent battery for an hour.
This has got to be some kind of calibration issue right?
