How to Protect and Extend your Gadget’s Battery Life

I just scored a new Motorola Droid 3, and this time, I promised the smartphone and myself that I would take extra good care of the battery. I didn’t want my lovely new Droid to end up like the Samsung Gravity which it replaced… i.e., seemingly needing a charge every 15 minutes or so.

“I’ll only plug you in when your battery is almost dead,” I said lovingly. “And I’ll let you charge until your tummy is all full before I use you again.” And then I trotted off to read up on batteries and charging, patting myself on the back over how good of a parent smartphone owner I was.

Whoops. It would have been a great plan if the Droid 3 used nickel-cadmium batteries. But like most modern electronics (smartphones, laptops, tablets, netbooks, etc.), the Droid uses lithium-Ion batteries. And they have very different rules.

The following tips are designed to give you the best possible results for the longest possible time, but your battery will die someday. And by “someday,” I mean you’ll be lucky if you get more than two or three years out of it (I’m so sorry). Even with the best tender loving care in the world, you’ll watch your battery get weaker and weaker all the time, and chances are you’ll notice shorter battery life after the first six months or so.

The good news: these tips can slow the loss to a minimum, and potentially add an extra year or two to your battery’s life, which, given the rapid pace of technological advancement, is probably as much time as you’ll want to spend with your laptop or smartphone.

How to protect your gadget’s Lithium-Ion battery life

  • The old NiCad batteries had a “memory” problem which trained us all to think that charging a half-full battery was the worst possible thing to do. Lithium-ion batteries are exactly the opposite. Any kind of charging will slightly decrease the battery life, but charging it when it hits 50% will hurt the least.

  • A good rule of thumb is known as the “40/80” rule. In other words, the ideal time to plug in your charger is when your phone gets around 40%, and the ideal time to take it off the charger is around 80%.

  • Don’t get obsessive about it. Letting your battery drop to 20 – 30% isn’t cause for panic, nor is letting it charge to 90 – 100%. You’ll shorten the life of your battery a tiny bit more by doing it that way, but not by enough to worry about.

  • Letting your phone discharge completely, or leaving it on the charger too long after it reaches 100%, will take its toll on the battery life if you do it often enough.

  • Your battery won’t hate you if you plug your phone in before bed and it has to sit at 100% for a few hours until you get up in the morning. You definitely don’t want to leave it on the charger for days, though… and if you’re really worried about this, there are “smart” chargers that stop when you hit 100% (in addition to helping your battery life, this also helps your electric bill and the environment!).

  • Some experts recommend you let your phone run all the way down about once a month, just to update the memory regarding what “full” and “empty” really mean. If you stay on the “40/80” rule for too long, you might start to see “5% or less – charge battery now” messages when you’re really at 45% or so (or ‘fully charged’ readings at 75%). Once a month, think like an old NiCad owner and recalibrate the battery by running it down and then charging fully. As far as battery life goes, you’ll probably end up with a net gain because you’ll have a far more accurate idea of where “40/80” really is.

Pro Tip: Enhance your phone’s battery life by switching to grayscale mode or setting the display to black and white.

How to protect and extend your gadget’s Lithium-Ion battery life: Conclusion

While lithium-ion batteries have different rules compared to older battery types, there are still ways to protect and extend their lifespan. Following the “40/80” rule, which suggests charging your device around 40% and removing it from the charger at around 80%, can minimize the impact on battery life.

Avoiding complete discharges and prolonged charging after reaching 100% is also advisable. Additionally, occasionally allowing the battery to run down completely and then fully charging it can recalibrate its memory.

By implementing these practices, you can significantly slow down the battery degradation and enjoy extended battery life for your gadgets.
