Laptop battery

Recommended Posts



I have asked here before about a battery that would run out really fast. Asked me to update all sorts of things and then I would upload a video to YouTube to see how long the battery lasts.

Yesterday after 3.5-4 hours it dropped from 100% to 30% percent. I did not have the option to leave the computer up to 0 so today I ran again. I see that after 3 hours and 40 minutes it dropped to 49%.

Why is there such a big gap between the test yesterday and today (I put the same video in a loop)?

Because what the laptop shows is an estimate of the battery time according to what is turned on at a given moment.

Note that this also happens if you add or take actions during the day.

That is, the mobile shows that it has X hours left and if you close an application or add, the figure varies accordingly.

I'm not talking about the time estimate that the computer shows.

I started playing it on a particular YouTube video yesterday and ran it in a loop. I came back 3.5-4 hours later and saw that it dropped from 100% to 30%. I could not let him continue to run until 0 yesterday, so I started doing another test today that is exactly the same. The computer is running the video, and I'm not touching it at all.

In that time period he lost 50% today compared to 70% yesterday.

He has been running for 5 hours right now and Otto is reaching 30% (about 33% right now).

It seems a bit strange to me that one time he lost 50% and a second time almost 50% more (70%)


At least this time the battery does not run out after 2.5-3 hours like I had at first.

Exactly the same. About 70% in both cases.

The only thing that was different was that in the first test the cable cable was connected to the mobile for a longer time (I realized that if I run the same video, after one time there is no need for the internet so I disconnected it earlier today.


Today - 5 hours and 20 minutes - reached 28%

Yesterday in less than 4 hours it reached 30%


the mother Should give a generally different performance?


And unrelated question, do you get the beep of the site when there are new posts? I noticed I stopped accepting him

There's a bit of a mess today with this.

Sometimes you click on a new message and you have to do a refresher to see ...

You will need to retry the cable .

With how weird it is ....

Maybe a ticket Also grinds the battery?

1.4 times? I have no experience with Not connected to electricity, but it seems strange to me.

I'll ask you (Although the representatives there are not the sharpest). I need the computer so I do not feel like checking every day :)

I do not know if there is. Maybe the computer sometimes needs more battery even if you run the same thing. I have no idea, so I preferred to ask (what's more, here you get more professional answers than at And the like).

I talked to them. Is it okay that today he used 79% of the battery for 6 hours and yesterday 70% for 3.5-4 hours (and that at that time the day took only 50%)?


What is the reason?

Maybe different uses etc.

But I used the same thing, I just turned on the computer and ran the same video on YouTube.




In short he told me at the end to pass him the battery log and he would check

Lenovo came back to me and said it was okay. They asked me to take out a detail of the battery (attached photo).

Apparently on the 13th of the month the computer operated for almost 7 hours and consumed only 37% and on the 14th of the month it operated for 6 hours and consumed 81% even though the uses were the same (on the second day most of the time there was also no internet).


The actual data displayed there is incorrect (there is a continuation of the report). On the 13th of the month it is recorded that I started running the computer at 11:11:51 with 68% when in fact I started running it at about 13:15 with 100%.


Even if you look at the real data I measured and even if you look at the incorrect data that came out in the report, in both cases there is a big difference in the battery.


Someone with mobile experience can tell me if he feels big differences between day to day when he is The same actions?

I connected the computer to an external monitor and closed the screen of the laptop. It makes sense that I get even worse data than with the laptop screen.

I checked yesterday. From 20:28 to 23:13 it dropped from 100% to 46%, meaning it would hold an order of magnitude of 5 hours without using its screen with easy use of web browsing, sometimes a bit Or watching the show.


If applicable, connect to a 24-inch screen with QHD resolution.
