Why do tablets take so long to charge? [ASK MR. NOOBIE]

QUESTION: Why do tablets (generally) take so long to charge? – Kyle N. from Indianapolis

ANSWER: While I don’t proclaim to know the inner workings and specifications of every tablet on the market, I can tell you this. Tablets have bigger (higher capacity) batteries than other devices like smartphones. And to me, the bigger the battery, the longer it takes to charge.

However, there are other reasons that may factor in as well. For example, how you charge your tablet can affect the charging time. Connecting your tablet to a computer via the USB port is not going to give you a lot of bang for your buck. Connecting it to an electrical outlet via a USB adapter will.

Use the right adapter

And speaking of adapters, it does matter which one you use. I recommend always using the one that comes with your tablet. Take the iPad for instance. Depending on which model you have, your adapter is probably a 10-watt or 12-watt adapter. The iPhone on the other hand comes with a 5-watt adapter. So if you are charging your iPad with your iPhone’s adapter, expect a longer wait.

One last thing. Your tablet should be able to fully charge from a depleted battery in anywhere from 4 to 8 hours, depending on what tablet you have. If you are charging your tablet all night and it is still not fully charged in the morning, there may be something wrong with the battery in your tablet and you should probably have it checked out.
