My tablet eats the battery some nights

[cobito]

Hello. A while ago I noticed that my tablet's battery was suffering a significant drop some nights. As I didn't remember exactly the battery percentages before and after, I didn't give it much importance. Tonight it happened again and I checked the battery log.

In the following image you can see the charge curve of the last 4 cycles:

You can see that in cycle 1 I used it less, but the total duration remains more or less constant in the next two cycles. However, in the fourth (yesterday and today) the duration is considerably less when I have given it more or less the same use.

In the following graph is the charge curve of a normal night:

You can see perfectly that in the early morning it remains completely horizontal, as it should be.

And here is the curve from last night:

You can see that it has been consuming battery all night. I don't know how long the battery of this tablet lasts, but surely no more than 3 or 4 hours of use (maybe 5), so if it were a normal discharge it would have completely discharged.

Is there any application that is playing tricks on me? I don't have much installed: Wassap, Skype, file manager, some small game...

Thanks.

It may be the play store updating apps automatically or syncing anything, try to cut off wifi when you don't use it to see if that's it

Also games with their notifications can consume you something, but I don't think that much

I have automatic updates for all apps turned off. Anyway, if it were some program doing "routine maintenance" is it normal to pull all night for hours giving it hell?

It's strange

Look at the battery consumption settings. There it tells you which programs consume more and the percentage of use

Check the battery usage settings. There it tells you which programs consume more and the percentage of use

That's what I'll do next time it happens because now I only see the consumption since I charged it (a while ago). Thanks.

As Mystique tells you, in the Battery section of the Settings menu, it shows you a list of apps that use the battery. If you notice that there is one that is going crazy, uninstall it and reinstall it again, as it may be a bug, or look for an alternative app that does not consume as much battery.

I started to get scared with the Z1 when one night it ate 45% of the battery by itself with everything turned off, only data on... In the battery usage I discovered that the "Media Server" was the damned process that was constantly and actively consuming 78% of the resources.

When I centralized the problem on it, I read and it seems that sometimes it happens that some app or process gets stuck trying to read some image, video or sound that is "corrupt" or that gives some kind of error, so it keeps running indefinitely in the background and that's why the battery discharges at great speed.

I read a list of possible solutions, but in my case I did two things, I don't know which one was the good one or if they were both, but they solved it for me:

1-I uninstalled and updated the Battery Doctor app, which crashed sometimes when I tried to see the charge history.

2-I deleted a few junk images, a couple of long videos and a strange image that the gallery didn't recognize (it smells to me that it was that one), everything was in the internal memory of the phone.

Here I leave the site where I looked at the possible solutions:

The same thing happened to me and in the end I discovered that it was an App to find out the passwords of the wifis that you have saved… quite a thing..

But being at specific times... it looks just like what they say above, maintenance or updates.

By centralizing the problem in it, I was reading and it seems that sometimes it happens that some app or process gets stuck trying to read some image, video or sound that is "corrupt" or that gives some kind of error, so it keeps running indefinitely in the background and that's why the battery discharges at a high speed.

I read a list of possible solutions, but in my case I did two things, I don't know which one was good or if they were both, but they solved it for me:

1-I uninstalled and updated the Battery Doctor app, which crashed sometimes when trying to view the charge history.

2-I deleted a few junk images, a couple of long videos and a strange image that the gallery didn't recognize (it smells like it was that one), everything was in the phone's internal memory.

Ok, perfect. At first I thought it was some kind of spyware sending my data to some place during moments of inactivity… that's what paranoia does.

When I know the process that causes the discharge I will act. In the meantime I will do a general cleaning of junk.
