Techie friends: My S4’s battery life has been really bad lately. How can I check if the battery has a problem?

Nagkaka buldge yung battery when it's going bad. So it's going to be easier to spin.

It'll spin longer if it has a problem.

Oops beat me to it.

work backwards, check the apps that you installed or updated recently. it may be one of those that's draining the battery.

Have you tried battery calibration? It worked on my Galaxy Tab's fast drain problem.

Can confirm battery bulge when it started dying on me at 20% power. I use an S4 Active, which shares the same chassis and battery as the S4, but with a poorer camera and slight water resistance built into the exterior. The Bulge is generally a sign of overcharging. (Even for a factor of a few minutes, cumulatively, it adds up and ruins the battery.)

To be clear, dying here means shutting off as if it had 0% power, though the indicator showed 20%. True enough, purchasing a new battery fixed the problem, and the bulge is quite evident when you compare the batteries side by side.

Check your battery usage under Settings app :)
