I have an 8-GB Nexus 7 that's about a year and a half old. Its battery life seems fine, but the actual charging takes an unreasonable amount of time. When it was new, it charged in about 2.5 hours; last night it took 7 hours to go from 30% to 60%. I'm using the adapter and cable that came with it.
Is there anything I can do to make my device charge faster?

Greetings - I "inherited" a MacBook Pro last year. It was a Apple MacBook Pro Core 2 Duo 2.4Ghz from Spring 2008. So it was 4 years old when I got it and I was told that the battery was dead and as long as I kept it plugged in, it worked fine, however, I would need a new one. So last year, I purchased a new battery and installed it.
However, I am still noticing that the battery life is horrible. It seems like when I am using it to type a document or check emails and surf the web, etc, I literally can watch the battery drain. I would assume that it might hold a charge of about an hour and a half maybe?
Is there any way I can "test" it to see what my actual battery life if? To ensure there isn't something else going on? Any suggestions would be helpful. Thanks,

How often, and for how long, should I turn over my car's engine in order to preserve the battery? [more inside]

How can I get a really really big rechargable "laptop battery"? Thinking 12-24 hours worth of charge on a laptop that can drain a high-cap battery in 1 - 1.5 hours. [more inside]

My Aspire 3680 (crappy laptop PC) doesn't want to hold a charge anymore, with either battery. How do I determine if it's my laptop, my batteries, or my charger? (I have a VOM and know how to use it).

How can I recharge my nearly-completely-drained car battery so that it will work long enough to drive it to get crushed? I'm hoping to avoid buying a brand new battery just to have it crushed. [more inside]

The "battery not charging" light on my dash went on; the mechanic told me I need a new alternator. Now the "battery not charging" light has turned itself off again. Does this mean my battery is, in fact, charging? [more inside]

Why is there no bat-acitor? (hybrid battery/capacity w/best of both) Is there some limitation in physics, chemistry, materials, etc. that prevents it, or has it just not been invented yet? [more inside]

A friend and I were charging the battery of a 2001 Honda Odyssey. He attached the cables to the wrong terminals of the dead battery. How much damage might we have done? [more inside]

I'm sure somebody else who's travelling over Thanksgiving could also benefit from this knowledge. I brought my cell phone with me on my five-day trip to my parents' place, but of course
I forgot the charger. The question I ask is: 'tis nobler to leave the phone on continuously and hope the battery pulls through, or is it a better idea to turn the phone off every night and turn it on only at the point in the day when I plan to use it? Does powering off and on drain more battery power than idling / the cell phone equivalent of "sleep"? FWIW, I have a relatively new Nokia 6682, and the battery is currently showing a full charge but I suspect it's lying, as I think it's been at least 24 hours since I charged it (that said, this battery's done five days unplugged before).
