hmm..ok thnkx

Same here. I believe it either cut off or do trickle charge after full coz phone will be cool after full charge when leaving overnight. If phone is warm or hot after overnight charge, then you got some concern there.

How long does ur battery lasts with moderate gaming?

I found it eat battery much faster compared to S3, drain almost same as Note 1.

All my previous phone Iphone, Nokia, HTC & Samsung always overnight charging with ori charger. Last week try S4 overnight charge with compatible 2A charger, in the morning switch on, my S4 hang & feel warm with no display. Took out the battery & leaved it till cold, restart luckily o.k, fuhh!

lol, u lucky only... if not, it will burn your phone

compatible charger from?

I use my Nexus 7 charger to charge both s4 and the tablet. I leave the Nexus charging during the day and charge the s4 at night. Been doing it since the s4 launch. No problems so far.

Samsung Compatible 2A charger(Made in China), bought at Tesco as my backup. My advice don't use compatible charger overnight.

any samsung original (1A or 2A) can charge this baby quickly and safely. my bad habit is leaving phone charged overnight on my s2 ori charger. still running fine (no symptoms of heat etc).

however, interesting note, i left it on my macbook usb overnight and it overheats.

Yeah charging fast..drain also fast..its time to flash to custom rom..any specific rom to suggest on better batt consumption?

But wont differ much right..need to get extra batt pack then

Is it possible, some wakelock activated and processor run hot. Got hit a few time with S2 with that. Other than that, I always leave my phone charging overnight. Bought another original charger to charge in office.

I read comparison between S4 vs S3 says S4 battery can tahan longer, but my personal experience its the other way.

guys, would like to check if stock recovery is firmware specific? or it's universal across all firmwares? thanks

me too. the under utilized 8 core is the culprit

Mine would last in under an hour. Samsung is well known for the battery life problems.

You can actually download firmwares from different countries.

It runs on 2 quaddies, so only 1 quaddie is used at a time. Performance is on the higher end one while battery life is on the lower end one.

If both run simultaneously, you'll get a burnt chip on a phone

Hi, any of you guys have problems where your S4 turns off by itself randomly? Even the battery is still like 30% or more full? And I can't turn it on just like that. Have to plug in charger only can turn on. Upon turning on the battery indicator shows that its far from empty. Hope its not a hardware issue. Any ideas? Stock firmware and everything. Never rooted.

My other S4's wifi randomly turns on and off. Try reflashing, factory reset, etc to no avail. Sent in for warranty.

If i were you...i send the phone to service centre for checkup.
Phone with untouched stock rom shouldn't behave like that.

mine is random reboot, but only occurs when I put it in my pocket.

so maybe mine is pocket problem.

ur pocket smelly? lol

how much to replace a S4 cracked screen at samsung? barely 3 months old.
