Galaxy s5 4600 mah battery?

Posted on 2015-01-07
Last Modified: 2015-01-07

I found this Galaxy S5 battery which delivers 4800 mah.
It looks just the same size as my current battery but would boost lifetime to almost double.

Just wonder if I can trust it.

Please advise.

Provision to provide extra power does not cause any issues. Make certain this is a Galaxy battery and specified for your machine. Make sure the voltage specification and connectors are the same. Make sure (if a third party battery) that it does not void any warranty.

That is a third party battery. The sellers have a lot of print about how they warranty their battery but are very coy about the Samsung phone.

There is a always a risk that overcurrent will cause issues with Li-ION batteries, and higher current batteries present higher risk.

Ask Samsung if the battery voids your warranty. If so (warranty voided), take care. If you decide to go ahead, you do so at your own risk.

Thanks, but that's actually what I like to know: it IS a battery specifically for Samsung S5, they offer other batteries with even higher voltages (but that makes the Samsung to big for me) up to 7500 mah.
They wouldn't sell it if it wouldn't be working at all if it would cause failure of the mobile.

If the battery is physically the same size, and the correct voltage, then additional power will not cause any issue, as I said before.

You need to get the battery vendor or Samsung to tell you about the phone warranty.

They wouldn't sell it if it wouldn't be working at all if it would cause failure of the mobile.   <-- Be very skeptical about this. It is called "buyer beware"

Let me give you a different story. I purchased a ThinkPad T61p a while back from an IBM/Lenovo partner where I live. I got a 3 year warranty. It came with a small battery.

One year later, I asked them for a bigger battery and they suggested a third party battery which was less money.

I asked them if the third party battery was warranty approved and they said Yes. The laptop worked just fine.

You need to get the battery vendor to say the battery is warranty approved for Samsung.  It does not so say in the link you provided.

Thanks but that's all very general.
Good luck asking Samsung if they would support this battery.  If they would ever answer, it would take months.
It's like asking Microsoft if I can install there OS on my own built computer.
Of course it is at my own risk. That's always the case.
I mean, I appreciate your answer but it doesn't give me much info about things I did not know.

I have winnowed this down to the very specific statement. Is the battery warranty approved? It does not so say.

If you are unwilling to ask or wait for an answer, then you must take your own chances.

@janhoedt  - Thank you. I was indeed trying to be helpful. You are probably OK to do what you want but I just cannot say with certainty. Good luck.
