Why is my Samsung Galaxy phone battery draining so fast?

Why is my phone battery draining so fast?

There are many factors that can cause abnormal battery usage or just the battery draining so fast. First you need to figure out if this is a software or hardware issue. One example of a software issue for this is that there are too many apps running in the background that are resulting in high battery usages. If it's a hardware issue, it's best to get your physical battery checked or replaced as it may be damaged and could be affecting your phone's overall health. If your phone is a little old, remember that batteries get worn out over time, so don't be too worried as that's completely normal for your phone's battery to drain a bit over the years. If you just got your phone, or noticed unusual battery drain then see some of the solutions below!

What can I do right now to solve this issue?

You can go the device maintenance setting or app to check your phone's battery usage, you should find the apps that are using a lot of battery at the top. In most cases, these apps are system programs that need to be running in the background and you shouldn't turn them off. You may find your other apps as you go along the list that have used a lot of battery, generally they're going to be heavier apps (e.g. social media, editing apps etc.) that you can always disable or completely uninstall. Another way around this is by putting apps you don't always use to sleep, this doesn't force stop or disable the app, however the app may not be able to receive updates or send notifications. This is quite affective by itself, but if you don't want to manually do this to each app, you can turn on power saving mode and adjust some of the battery limitations to help save even more power.

What do I do if my battery is damaged?

If you're certain that it's a hardware issue, then you should check your battery. Take apart the phone and try reconnecting the battery to it's place. Your battery could also be damaged because you're using a high brightness level all the time, you're not clearing unused background apps or you may have accidentally got water through the charging port. Most Samsung phones can resist a bit of water splashing about on the phone, but if water has gone directly through the charging port then your battery could be in a terrible condition. Usually you get a little pop-up message on your phone, saying 'Unplug charger, Moisture has been detected. Unplug the charger and make sure both the charger and USB port are dry' if there's something wrong with the charging port/battery. Have a look on eBay, Amazon or other sites where you can find a brand new battery that is compatible with your phone. You need to make sure you're getting an unused battery for the specific model.

Hope this helps, Sanuka!

Great post @SanukaK !

However, not all Samsung phones have detachable batteries. So, if there is an issue with the battery, I would advise allowing a Samsung engineer to inspect this.

Hey, @SanukaK  and @KholaI 🖐🏻

 

  • I had that problem my earlier phone which was Galaxy A40. One day it just began to drain battery every time when battery's charge goes below 20-23%. Battery held charge and gave power normally, until charge goes under ~23%. When that happens, I had like 3 minutes time to put phone to charger. It doesn't end or slow down battery's fast power drain, but when charge goes to 0%, then phone didn't shut down. Then it slowly charged phone again to max power. If I didn't put phone to charger, then it turned off. I've never dropped, let phone to go wet and it never get any impact from the outside. Also phone never give me any notes like "USB-head is moisturized". Before that phone I had Galaxy S8 and that phone told me when it was sweat or something else 

 

  • So it remains mystery for me why that Galaxy A40 battery does drain battery when there was about 1/4 charging left. I've never take it to the telephone service because that time I had service where I need to pay first so much, that it wasn't worth of it and it was cheaper to buy a new phone.

 

  • My point here was that there is so many different types of problems with batteries, that one answer couldn't solve them all. 😕

Regardless of what anyone on this community says, the Exynoss chipset is probably the worst performing for standby battery drain EVER. After coming back to Samsung after 6 glorious years on Huawei battery life, I found out Samsung is just as bad as before. At least I realised my mistake before buying 4 of these ***** battery life phones. Cheers Samsung.

Thanks for your reply, and yeah I agree, Samsungs are great phones but the biggest flaw are the exynos chispets. They performs so badly even compared to older snapdragon chips. Samsung should do something about their chispets, at least we've seen very little improvement with the Galaxy S22 lineup chispets. In terms of other hardware in the device, they're certainly ahead of the game when it comes to quality and performance. At this point it's just exynos chispets letting down the rest of the phone.

The pride of the Samsung brand has been going into deep cores of drains in recent times.

 
A bunch of compelling bloatware is one among the crooked & cunning fundamental issues in Samsung's design. It drains the battery much faster than other brands like Moto,vivo, oppo, xiaomi, etc...
 
Although apps not used added in deep sleep mode, lowest brightness, games not used ( but game related services keeps restarting cunningly) animations turned off- samsung Apps which are not required at all, keep restarting in the background to drain the battery.
 
 
The battery drains radically even during the 4g call duration .
 
Even the maximum battery saver does not work like the estimated time shown in the app, 

Medium power saving mode stands better in comparison.  

 
We are suppose to experience long lasting battery life rather than struggling with various settings here & there ,
but 
Samsung brand executives nevertheless agree on these facts, they are probably well trained at bluffing customers by explaining lame reasons. Samsung seems to to be incapable in addressing this issue for all these years,
If Samsung team is seriously concerned about its honest customers feedback it should release battery patch for all the versions to retain them for future business, Else we wont be surprised to see Chinese brands suppressing or surpassing Samsung in all the zones of competition.
