Battery charges super slow, battery doesnt last long neither. Should of got a Surface?

need to test charger --port and battery

You should have had in the box with your Surface 3 Tablet a charger. It will have a plug with 2 points that is for your power plug, and at the other end you will have a natty little flat magnetised plug for the side of your Tablet. Mine is at the bottom right slot, looking at the screen of your Tablet. Now when the power is turned on, a small bright light will glow. That is now informing you that the battery in your Surface is being charged. Now at the bottom right of your Task bar, that is the Bar on the bottom of your screen where you can place program short cut Icons for your convenience. Now the speaker Icon which is there toward the right-hand side and has a cross if off, or a different look when on. Now the next icon on its right is the one that tells you how much charge is in the battery, if you touch it, it will come on to the screen informing you how much charge you have in the battery. If I'm using my Surface a lot and I do I keep it on charge while I work as a precaution to keeping my Surface well topped up. Hope this helps.

Since it's brand new, return it. You didn't say what type of tablet it is, but they should last for many hours on a charge.

There are no surface pro 4's or 5's yet unless you are an engineer at Intel. If you want it to stop discharging so quickly- turn it off, and no I don't just mean put it in standby. You need to power it off completely- that way you will keep it from eating your battery when not in use. These things boot so fast that the inconvenience of 15 seconds is not worth the hassle of a dead battery coming out of sleep after a day or so.

You have a problem with the battery or charging line. If you have indication from Windows for charging battery, mtery.aybe you need a new bat

i never used a kindle . i have no knowledge of its engineering.
yet to me there seems to be many thing that you could check.
1 worn out lithium ion battery(the capacity of a lithium decreases if its charged at a high rate or just too many times).
2 burned out fuse in the charger(if so, then it's prolly a surface mount fuse)
3 the charger receptacle on the kindle has one or more cracked traces or solder joint on the PC board.(abuse causes the receptacle mounts on a lot of large things to fail)
wander if you tried a different charger? or with very light pressure, like handling a jellyfish, holding the charger interface plug in the receptacle at an angle(be careful not to do that too hard or too much cause thats what breaks em yet thats how you can tell).
lastly the battery can be replaced it you should ask a used computer tech how. i think it involves very very slowly and carefully slightly heating the whole unit to heat the contact adhesive to unstuck the battery without ripping open the plastic battery or destroying the unit.i have removed batteries but lots were destroyed. lol. i never used heat. just very slowly lift it and the adhesive releases over a period of several minutes or patients.

sorry of its all worthless to you.

oh yea.. and very lastly.
you could try wiring a vapor pen charger directly to the terminals of the battery if can't find any fixable bad connections.

i say "vapor pen" charger, cause vapor pens use a very slow charge rate and it can extend the life of your battery greatly to charge it slowly instead of 2 amps or whatever and the charger units are like a buck on eBay.

good luck :D

Check for dirt in charge port; if dirty try a clean dry toothbrush to clean the contacts.
If still buggy, consider taking to store and see if it charges with sample power supply.

Same problem on my Samsung Galaxy Note 10.1 (GT-N8013) w/ OS 4.1.2

It just boots up and shuts down.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced.

The computers contact point for the charging cord is "VERY" sensitive for me. I had to try many times to actually see the charging "icon" light up before letting it charge. Many times the icon would go back to "battery" during charge and I would have to re-try the connection again... Very annoying. If the battery get so drained that you can't see the "charging" icon, then it's a guessing game as to whether it's charging or not. I needed to re-install the OS and it took me 3 days to get my battery charged that way.
