Default [Q] Peculiar problem with S4 battery

Hi,

My GT-I9500 is pretty new (bought around 4 months ago). For a few days I am facing problem with my battery. When battery is around 60% my phone reboots and then show 0% batter. Charging it a minute restores batter life to 60%. Here is the sequence of incidents after which I am facing my problem (don't know whether any of them is relevant).

1. I accidentally (playing games) discharged my battery to 0% for couple of times recently.
2. My problem started after I installed batter doctor to improve battery life ( don't know whether its the cause.). Not, that I had any complaint with previous battery life
3. Uninstalled battery doctor and did a full charge... problem persists
4. Reinstalling battery doctor and did a full charge... problem persists
5. Did a h/w reset.... problem persists
6. updated stock firmware through odin... problem persists

Any ideas why this is happening?

Note, that before step 6 my device was rooted so warranty is void.

Thanks in advance.

Ok, I fu....d my battery. What I fail to understand is how?

The only control user have over a battery is charge/discharge cycle and whatever he/she does can't modify chemical composition of the battery that much to cause the symptom I am having.

This is a common and well known fault with a batch of batteries.
Mainly the batteries where the serial number starts BD. Is your battery swollen?

Take it back to where you bought it and ask for replacement.

P.S You didn't break your battery at all, it's a manufacturing defect.

No worries mate.

Just Google search "Galaxy S4 faulty battery" and you'll find lots of pages about it.

Samsung are aware and have acknowledged the issue so you shouldn't have a problem.

I'm in NZ, the same happened to my gf phone and within 2 days she had a replacement battery direct from Samsung NZ.
