    Samsung galaxy grand1 has default alert settings for battery status at 30%, 20% and 10%. I have noticed the following.
    a) My phone switches off automatically when call comes when battery charge exactly at 30% or 20% or 10%. It never boots when I tried to switches ON. The only way to switches ON is to connect to charger. It is happening frequently since a couple of weeks.
    Batter status shows 30% or 20% or 10% after switches ON where it switched off.
    b) Battery dried up fast when charge dropped below about 15%.
    c) Recently, batter got discharged from 100% to 0% very quickly within 4 hours even though I haven't used much; no power consumption apps/wifi/gps are active. Only once experience it.
    d) Also, I notices battery dried when charger connected to phone and power switch is OFF.
    f) But battery is normal otherwise.

    My phone is 1 yr and 4 months OLD.
    Anybody can suggest me what might be root cause and a solution . Batter pack or software or hardware. Thanks.

    It is only the China made battery's that have this issue apparently. Mine swelled up and my screen has bent and lofted slightly. Taking to the service centre tomorrow.

    After reading this I realized that it is a battery issue. I just ordered a cheap but good 3rd party battery today. I wondered If i had bad water damage due to a sever car accident and my phone layed in a puddle of water on the floor. Thought maybe this hurt my battery but the phone worked great for weeks as I was in the hospital and just began its sudden death cap.. Thank you all for your help

    This 30% is that battery indicator is broken all you need to do is charge it full and restart it

    Hey All,

    I recently had the same issue with my S4 and I came across a very cheap but effective fix. There is an app on the play store called "Real Battery" that scales your battery level down to the percentage it dies it. My phone kept dying at 30% so I set the indicator to 30% and it scaled my battery level so that 30% is my new 0%. It lets you know more accurately when your phone is about to die, so that you won't be fooled when your phone says it has charge. Check it out, its called Real Battery.

    I'm having the exact same issue with my S6. I have taken it to a Samsung repair center where they replaced the battery and did a flash reset. 3 days later, I experienced the same thing. My phone reads 30%-40% remaining, but dies while I'm using it. I plug it in and it starts its charge at 0%. So frustrating not knowing when your phone is going to crap out!

    I have two S4, personal and corporate. the first one, its battery lasted about one and half year. I was travelling and it was taking whole night and some more to charge 100%. then i bought another battery in first shop i found one, that lasted 3 months, swelled. the third battery had same symptom, was switching off before using all the charge. after many temptatives you all know listed in many forums, my problem was solved wiping the conector, and most importante, inserting a small piece of plastic to the opposite side of conector, so that it presses the conector for best contact.

    the second s4 came with defect, it was sent three times, 6 months to get repaired. at last they told that changed the mainboard, and finally is working well.

    I used to charge them every night, all night, so I had full charged to go to work. this practice is not recommended, after 3 initial full charge and full discharge, i was told to not charge more than 3 hours, that is enough to get 100%. nowadays i wait the recharge warning.

    Same issue with my wife and my Note 4's. Factory Reset hers and rolled back from Lollipop, and problem goes away, mine continues. With Lollipop, it seems like there are bugs making the phone do this even to a good battery.

    Hi All
    I have using this phone for almost a month now. my phone seems to switch off at around 20 - 30% of battery life. My friend had brought this from China. And it also shuts down when a lot of applications are open at the same time.
    Please help me sort this out.
