Battery – is it a bad idea to keep your phone charging all the time?

The first part of your question can be found under Ideal charge / discharge percentage for maximum battery life. The answers there explain in detail, so yes, that's it true

Second part afterwards how long… depends on how often You charge it incorrectly, your usage (how many charging cycles) etc. and you can't put a number on it. Remember that batteries will lose a significant lifespan even if they are not used due to aging. For more information, see the answer here.

Should I disconnect the HDMI cable from the laptop when turning off the laptop to make sure my monitor doesn't waste my laptop's battery

Should I disconnect the HDMI cable from the laptop when I turn off the laptop to make sure my monitor doesn't waste my laptop's battery?

I am using an MSI Leopard 8. GP63 laptop which is good. And when I edit in After Effects, I see that it goes up to 12% in less than an hour. So can you tell me if this is the cause? Because I didn't see anything like that before I got the monitor

Battery – Sony NP-FH40 does not charge well

The answer is probably very simple: the battery is empty.

Lithium-ion batteries lose some charge when stored. The self-discharge rate normally stated by the manufacturers is 1.5–2% per month.

If this period is extended, they can be deeply discharged, which can damage the cells in the battery.

As a result, they lose a lot of capacity or can even be damaged so that they no longer have a real charge.

Please also note that the batteries age and this effect also leads to a reduction in capacity.

The good news is that they have become cheaper and a new one will bring you back around $ 15.

Battery Life – Understanding Samsung Power Settings

I'm pretty confused about Samsung's "App Power Management" page.
There seem to be several overlapping settings:

  1. Adaptive battery – Limit the battery for apps that you don't use often
  2. Put apps to sleep – Put apps to sleep when they haven't been used for a while
  3. Sleep apps – These apps don't run in the background
  4. Deep Sleeping Apps – … never run in the background …
  5. Apps that don't go to sleep

Here is my interpretation:

  • (1) & (2) sound like exactly the same setting. I'm assuming that (1) is the standard Android 10 implementation, while (2) is the custom Samsung version, which may be older than Android 10 and possibly more aggressive? To be honest, I'm not sure why they keep both.

  • The same applies to (3) & (4). Both sound the same to me. Again, it looks like (3) the original operating system setting and (4) a Samsung thing.

  • I assume that (5) is an exclusion list for apps that are not covered by (1) & (2).

  • None of these settings relate to doze mode, and even if you put an app under (5), dozing is not disabled for that app.

Would love to get more details when you have them.

The battery door switch on the 1100D is defective. How can the problem be solved?

Yesterday, a tiny plastic part broke off the microswitch on the inside of the camera housing and turned it into a fancy paperweight. Why Canon would make the most important part of the camera from less than a millimeter thick plastic is a mystery to me.

My question is: is there a way to override this switch? I have never needed the functionality provided by the switch and do not intend to start now.

iphone – From which state of the battery does iOS start to reduce performance?

I have an iPhone SE with iOS 10.3.3 and am planning to upgrade to iOS 13. A third-party app stated that I can charge up to 80% of the capacity of my battery. I know it takes less time than when it is new, but it still works pretty well and is perfectly fast. I also know that iOS 13 discharges the battery faster than iOS 10. But would iOS 13 be an additional problem with this battery performance, leading to a performance limitation that would not occur in iOS 10?
