Dear colleagues , I know that the problem is already common battery of S4 .
Got aa S4 ( model i9502 ) recently , I know that there are sites that say that Samsung has admitted the problem , but the samsung store in my town did not solve the problem . Before you go back and / or take other measures , would embassar me a little more .
In short , the phone has downloaded very fast until I installed the app drain battery analyzer to try to understand what has occurred .
Another thing I noticed , the cell was 69 % battery only open adobe reader, then hung up and put a sd card and turn on back, after showing only 52 % .
Another detail , I turn off the S4 and did not take more than 2minutes to make this whole process , and when I turn on again, the % of the battery has fallen enough, the date/clock unconfigure of 2014 to 2013 and clock has changed too. Typically phones even if turned off and removing the battery with litlle time between turn on and turn off keeping date and time , for example in s4 of my girlfriend, I do this, turn off put off the battery for about 3 minutes and put it again, and the clock it was configured normally, this usually helps get a diagnosis ?
And like I said , it drains very fast , and turns itself off before the battery goes to 0% sometimes , for example , sometimes have shows that 50 % of battery and turn off anyway.
Detail , the battery temperature is normal, the app shows usually 22 º C.
Another problem I noticed , had a day that was showing 47 % battery indefinitely , direct, and with the app adobe opened, strange was showing 47 % - have stayed that way for so long without even changing the percentage , rebooted and then called again , and was 22 % , ie , apparently the battery meter stop tocount the % and not show the real situation , the OS of my phone will be some bug or the problem are battery itself ?
Will this be a problem in android , or battery ?
Already setting the cell for maximum economy with power saving mode on , with a minimum brightness with function close applications when you leave, and nothing worked .
( if only buy another battery , somehow the lesser of evils , indeed , less worse than being a problem on the device itself ) but currently have no way to buy the battery and take to arrive , and would also be frustrating to buy another battery and problem still occurs , then I would know a way to check what is really the problem , to make arrangements from there .
After that , I also did a reset erasing everything that was in the cell for it to stay as factory . And not solved .
Anyone have any suggestions ?
Thanks in advance .
