Is the wall charger one by Samsung, or a third party? If it's the latter, I would suggest either getting a Samsung charger, or finding a charger that can charge 2.1A. 1A capable chargers are passable, but expert the output to be much slower. In any case, turning off the tablet and allowing it to charge should charge faster than when it's on.
Now even if you get a better charger and your Samsung Galaxy Tab 3 is still losing charge faster than getting charged, you can look at getting the app like Battery Stats Plus (it's free) and it can tell you what's causing the drain. There could be an app that's constantly awake that's causing excessive draining. Worse case, there's the possibility that the battery is no longer functioning properly. That then may require battery replacement.
Nothing happens when you turn the key: That about says it all, you turn the key and nothing happens, no crank, no clicking, no nothing. It's totally dead. Possible causes: 1. You left the lights on again: ump start the car and remember to turn your lights off at night. 2. Battery is dead: Test battery and charging system. Replace battery. 3. Dirty or loose battery cables: Clean and tighten cables as required. 4. Problem in the charging system: Test and repair charging system as required. 5. Bad Neutral Safety Switch: Replace Neutral Safety Switch.
A loose / slipping alternator belt, or the alternator itself is gone bad.
best way to tell if the alternator is charging is to unhook the battery with the engine running, if it shuts off then you know you have a bad alternator, i wouldn't recommend this with newer vehicles due to the fact you could hurt the computer but an 89 i wouldn't worry about that so much, good luck!
That means extracting energy from rf wave and using them to power up the devices.... -by T.dinesh kumar(mcet)
Sometimes there can be enough power in the battery to run electrical things but not enough to start the engine. You need to get the battery tested to see if it will hold a charge.You can try to jump start it using another battery. If it will not start this way,try charging the battery first before going on to the starter. If it turns out to be the starter, you can have it rebuilt. This can run about 20.00-40.00.
You simply cannot as it is THE battery that you are charging...
The way to stop your laptop from charging is to unplug the charger from the computer. When the battery starts to get low on power plug it back in.
battery is on its way out or its not charging properly
not charging the battery properly... check the alternator.
After making sure the battery was completely dead (on a Samsung Intensity). It took almost 8 hours to finish charging
no, the light has nothing to do with the alternator working properly, the light is only to warn you that it isn't charging the battery properly.
Dead or weak battery? Alternator not charging battery properly?
Your alternator might be bad and not charging your battery properly.
If your battery is not charging properly the charging system warning light ( located just to the right of the " F " on your fuel gauge ) will light up . It is the picture of a battery
Battery is either defective or the charging system is not working properly.
That's not 12 amps,that's 12 volts,which means the system isn't charging Measure the voltage across the battery terminals,if its charging properly,it will be between 13.8 and 14.7 volts,anything less and its not charging. Suspect then a faulty alternator or wiring problem. and have the battery properly recharged and tested too,a low battery will not give you a correct charging reading and a faulty alternator can take its toll on a battery.
take the car to a repair shop and have them put a battery tester on it. it may be the alternator or the battery the tester will tell
