bad charging and battery problem?
Following problem this time :
Samsung galaxy tab 3 8 inch tablet is working fine : battery percentage is ( for example) 56 percent. one second further the tablet says : only 4 percent left , please charge ...
sometimes the battery is dead, i recharge the tablet , but a few seconds later i see that there is 80 percent battery ?
also charging is soooo %#*@ slow... for example : 2 hours of charging for 10 percent battery ....
could it be the battery ? ( it will be the 3rd battery in 2 years)
could it be the charching port? bad connection?
how do i measure this on the battery and or the charching port?
could it be something else?
i always use a genuine charger , and also tried an other charger... ( offical charger) ...
thanks in advance
Hey Guys thanks for the help so far.
I opened the tablet,measured out the battery :
6 wires :
2 x 0.0 VDC on black wires
1 x 0.0 VDC on yellow
1 x 0.32 VDC on yellow
2 x 3.72 VDC on red wires.
( measured 4 times to be sure.)
now measured out the charging port : ( as good as i could ) i measured 5.05 VDC on that connector.
(measured 2 times ...)
so it looks okay ... i gues, what do you guys think?
problem on the main board? bad or faulty diode or capacitor or...
The battery is already ( under warranty) replaced 2 times (once at 6 months old and now 5 months ago) . and 1 time the charging port... i think thats not quit normal.
the tablet is now 2.5 years old. and out of warranty. i could replace the charging port and battery but here in belgium those parts cost 60 euro ... so i have to be sure..
