I have a samsung s8 and if the battery gets to 55% it drains and shuts down within 5 minutes. Its very annoying and been like that a while. Can anybody suggest what the problem is? 

If it’s anything like an iPhone it sounds as if the battery needs re-calibrating. This will mean running the battery down to nothing and when I say nothing I mean emptying it by repeatedly switching it on every time it dies and using things like playing music or turning on the torch to speed up discharge. When it is completely empty you need to charge it up until it reaches 100% then leave it on charge for a few hours more. You need to repeat this process two or three times and then the battery meter should read 100% when full and 1% just before it dies.

OMG,better to change a new battery or new mobile phone.

A bit drastic when the tips mentioned above have a very good chance of sorting the problem.

 

The part about repeating the process is certainly one to note.

replace it, re-calibrating or whatever wont work, as modern batteries Li-Po or Li-Ion have almost no memory effect, (as opposed to older rechargeable batteries)

 

its likely that the battery has degraded and needs replacing..

 

One thing i would try though, back up all your photos etc, and reset the phone, it could be some software draining it (though not as likely)

It is not  the battery which is being recalibrated, it is the software which produces the battery state of charge indication, by redefining the ‘full’ and ‘empty’ points which become lost after time.

Sorry no, modern phones/batteries don't need to be 'calibrated' or even re-calibrated' etc - it's a falsity.... 

One of the MANY articles on the subject...

Android phones use lithium-ion (Li-ion) or lithium-polymer (Li-po) batteries. Such batteries don’t need to be fully discharged, and come with smart chips that make calibration unnecessary.

Battery calibration is a remnant of older nickel-based batteries (usually nickel-cadmium batteries) that were used widely in laptops till a few years ago. Here are the facts.

Just google it, there's 100's of links about it, all saying it's not needed/wont make a difference etc....
