This is infuriating. I too have a Samsung Galaxy Tab 3, 10 inch. I let the charge drop below 10%. And now I can't recharge the device. The behaviour is bizarre. I have many micro-USB cables, and many charging options. Using only cables that have shown, on any device, to present any power to the Tab 3, here's a sample of the results:
- iPod 5W USB Charger: Nothing
- Apple 10W (iPad 2) USB Charger: Nothing
- Apple 12W (iPad 3) USB Charger: Nothing
- Apple iMac: starts charging, but the iMac can't sustain the current
- Apple Mac Mini: starts charging, but can't sustain the current
Who wrote the battery management software and tested it? This is badly written, badly tested code. I'm seriously annoyed. The idea that one has to monitor the battery usage and avoid discharging below a certain point? What other device do you have to do this on? I can't think of a single rechargeable device that I have to do that on.
I and my family have, at last count, 15 intelligent USB rechargeable devices (including iPhones and iPads, 4G dongles, smart bicycle headlight, ancient Tom Tom GPS, bluetooth mice, bluetooth headsets, etc), and seven laptops of various types. Not a single one of these other devices has a problem with being completely discharged and recharging from a point at which they refuse to switch on. Not one other device has this problem. Not one. Except for the Samsung Galaxy Tab 3.
I'm not at all happy. This is bad product management, and an unacceptable design flaw for a modern product.
I tried all the helpful advice here except for the parts involving disassembly and reassembly: my device is well within warranty and I want no dispute about me having opened it and interfered with it. I shall be taking it back, and asking for a full refund. I'm not going to become an external battery monitor for a defective design. I don't usually get this annoyed over product failures. I understand that some things might not work. I usually just shrug and move on. But this is a known problem, where the manufacturer has chosen to issue frequent updates for the applications they force on you (Samsung Play type stuff), instead of fixing a basic battery management design flaw. That's just very bad product management, IMO, and a betrayal of the brand promise. I might as well buy unbranded products, if a brand ships defective equipment that it refuses to address, under its' name. Vexing. Timewasting.
Thank you all for your generous help on this forum. I deeply appreciate the attempts to help.
