Battery Problems

[Matt]

Hi 

When my battery gets to 22% it seems to drain quickly down to 0% when it gets to 22%.

is this a Battery Problem or a App/software problem.

My Galaxy A13 is running Android 6.0.

Is anyone else experencing this problem and what can I do to stop this from happening.

Thanks

Matt

Hello Matt,

I would advise you to observe/document the problem with your A13 more closely. I don't know if this was a one-time problem or if it really starts losing battery at 22% quicker and is a repeatable problem. Even if determining the battery capacity is not that easy, a smartphone should be able to estimate the battery level. This is also important for the user, otherwise you will assume completely wrong circumstances and can even get into problems if the device incorrectly estimates the battery life.... 22% battery should last at least as long as from 44% to 22%. You rely on the device and the information to a certain extent.

I would therefore recommend monitoring the device when not in use (e.g. at night) and noting the battery level.

I don't know how old your device is either, maybe the battery has a problem and loses too much voltage at a certain point. But I have no idea how or whether the devices determine the battery level, there is absolutely no information from the manufacturer. It's also worth looking for external causes. The standard suggestion is to look for apps, perhaps the device was in a corner with poor reception and more power had to be used to maintain the connection, updates. You should rule out everything as a cause.

Example:
My A14 and a second A14, which definitely has some strange problem and always starts losing battery massively after 10 days of system runtime.

hi, out of topic but I just wanna ask something.. when I first bought a13 the battery life says "2 days left" and now it only says "15hrs left" why is it decreasing?

Hello @nin1 

I dont know your battery level in relation to your remaining runtime.

From my observation, samsung smartphones take the usage SOMEHOW into account and battery runtime is adapted.

That doesnt mean that the runtime is correcly estimated. In my use case on several devices (A12, A14) the runtime ist completely wrong and unlogical, even there is data to prove a longer runtime. Especially if the battery lasts a week, two weeks or a month or more, the runtime is completely wrong. Samsung shows completely wrong values ​​for me It seems, that the Samsung "Guesswork" on some or all(?) devises is based on a fictional average usage time (on many devices 4d 4h) and based on this value, the runtime is adapted ....somehow.

I would definitely recommend restarting the device, looking at what's running in the background and closely observing what the device is doing. If the product is working correctly, you would assume that you either use the device a lot or that it is otherwise subjecting it to high levels of wear and tear. You haven't written anything about that.
