I have a MacBook Air (13", early 2015, i5) that had a bad battery. I just replaced it with an iFixit battery. After calibrating as directed, it was still running all the way down in less than 4 hours, so I reset the SMC, and that hasn't helped. Should I ask iFixit for an exchange and try another battery? Is there something else I should do? [more inside]

hi all, I'm debating whether to buy an XPS-13 2017 and a 2014/2015 MAcbook Air 13" I prefer to buy second-hand laptops so I can reduce my environmental impact. They both SAY that they have a long battery life, but how long are they really? For me, battery life is the biggest criteria, and I'm hoping to have a PC with a very long battery. I've found Macbooks to be fairly reliable and long-lived, and easy to get repaired if need-be. My last XPS got a tad wet and died. Really bad experience. It had amazing battery life though. If battery life is the only / main criteria, which computer will last longer, daily, really?

I am in love with a pair of (women's) shoes that have LED lights in them that twinkle when you step. I am unlikely to wear them more than 2-3 times a year. The shoe's FAQ says they should last for 10,000 steps. Assuming I am not walking all that much when I do wear them, how long will they last? [more inside]

Is there an OSX utility that will notify me if my battery time remaining suddenly decreases, e.g., going from five hours remaining to three hours remaining by opening a certain website? The fan spinning is a hint, but it isn't reliable. I've googled this but had no success.

I have a new-old Droid 3 (bought new, only started using it recently) and it's not holding a charge very long, even when I'm not actively doing anything with it (it can drop from 100% to 70% over night). I looked at its battery usage, and the bundled apps that I didn't want or use were using a lot of battery (YouTube was the worst, at 27%). Should I try some cellphone management apps (examples), get a new battery, root it to uninstall bundled apps I don't want or need, or root it to run a custom OS? [more inside]

My cheapo Android tablet finally gave up the ghost. I'm in the market for a new, nicer one and thought about getting the Nexus 7*. But searching around, it seems to have a lot of problems with battery life, even when on stand-by. I don't play games or watch videos or even listen to music much on a tablet. My main use case is reading and annotating pdf articles and books, especially when traveling (long flights) when battery life is kinda important. Are these battery life concerns for the Nexus 7 founded? Is there another Android** tablet that does better? [more inside]

My Android phone, a Samsung Nexus S, operates on Jellybean 4.1.1. Since the latest update, I've noticed a dramatic decline in the battery life--it will go from fully charged to dead within 3 hours of intermittent use, regardless of whether I'm on a 3G or Wifi connection. How can I optimize the battery life on my phone without losing its functionality? [more inside]

So Energizer or Duracell? Or some other brand? I'm confused. Apparently they are both 5 times more powerful than the other. I'm looking for the best value-for-money AA battery on the market (i.e. battery hours per dollar). I understand it depends to some extent on the device. Let's say two devices - the TV remote control - and a digital camerra. Anyone have a link to the definitive report? [more inside]

I've got batteries on the brain today (slightly-earlier post about aftermarket laptop batteries), but this thread and my growing frustration with my increasingly-relied-upon cell phone brought to mind another question: how much battery life does your cell phone really get? No matter where I am, how much I use it, or even if it's on or off, my Samsung SPH-N400 gets 24-36 hours per charge, at best, compared to the advertised "Talk Time: Up to 2.9 Hours, Stand-by Time: Up to 7 Days."
