Batteries need to be cared for properly — they’re a critical part of our mobile devices and battery technology hasn’t advanced as fast as other technologies. Unfortunately, there’s a lot of incorrect information about batteries out there.

The problem with leaving the laptop plugged in all the time... The battery will wear off a lot faster. At least 3-4 friends and a lot of other people I know around, inclusing myself, have done this mistake. Brand new batteries, laptops just bought. Out of laziness and getting used to leave the battery plugged in, considering "it's not charging anymore if it reached 100%" they were simply using their laptops like that plugged in all the time. Well, those batteries die after less than a year.
Use a battery correctly, as in charge it, remove the plug, recharge it, remove the plug, and so on, makes the battery still work even after 3 years.

I always keep my batteries in the freezer and I feel I get full use of them when put in use.

What are you talking about? I always keep my 2010 netbook charging when I use it, and the battery amount hasn't decreased by more than 15 minutes.

When I use my notebook, it's almost always connected to the AC. What I love about the Lenovo G570 is it has its own battery management program that can be set to maintain a battery charge of only around 50% to help prevent premature battery degradation. I let it charge to 100% if I anticipate I may be using it without AC.

My Fujitsu A1120 laptop has been in regular use since '08, and if there has been any battery degradation, it has been little enough to be unnoticeable. It's rare that I use it on battery power. It's generally plugged in, and unplugged about once a month, to discharge to 70%, then plugged back in.
My dad used to store spare batteries in the freezer. In those days, they would have been alkaline. I don't know if the science crosses to ni-cad or lithium batteries, but I think I'd go with, "Couldn't hurt".

What about doing a "Full recharge" from a Battery Doctor app on iPhone and iPad? It says to periodically run the battery down to ~10-15%, call up the app and run a full charge cycle. I do it once a month. Good idea, or bogus? In other words, do repeated, daily partial recharges shorten battery life?

Good article. I have actually done a lot of research into LiPo batteries for a project I am working on and discovered all this myself. The big surprise for me was that batteries should be stored at half charge or less - the opposite to SLA and NiCd!

If a battery's life is measured in charge-discharge cycles, it would seem that the thing to do is to plug in the device when one can, so as to minimize the number of those cycles. I do that with laptops, trusting the circuitry to not overcharge (Lenovo seems to have particularly intelligent charge management) and have gotten years of life out of my batteries.

This is what I am looking for, how to use or take care my gadget battery. I used to discharge my phone to 0%, but when I read the article, I am wrong. Thanks for the information .

So, Does it matter if I don't fully re-charge my phone before removing the charger. eg putting the phone on charge whilst in the car and then removing it when you get to your destination but the battery isn't full yet? tia

There are many new ways of charging your phone on-the-go via cases or portable chargers. Being so new to the market are these charging methods safe for your phone battery? Will a charging case cause the battery to overheat to much?

Hopefully, your device will be due for an upgrade by the time its battery dies.
I would suggest differently: Only buy devices where the battery is easily replaceble and a new battery is readily/cheaply available. On my thinkpad x200 i'm on my third battery after over 5y of usage.
Don't throw away your devices just because the battery goes weak!

Same here. My 2 year old netbook gets used every day, and it still gets at least 3 hours on a charge. Since LiPo batteries have a useful life span of maybe 3 years to begin with, I'm absolutely fine with the state of my batteries.
My Dell laptop has a nice feature: it charges the battery once after being plugged in, then stops charging it. It will only fully charge the battery maybe once a month or so.
@greeneyedsouls, the problem with you and your friends is probably just due to heat-based breakdown of the cells, not overcharging.
#16 By: Tom Wilson, January 16th, 2014 11:40
Actually, that's better for your batteries. the longest-life scenario is to charge our battery to about 85%. That should put the cell voltage at around 4.0v. Charging the cell above 4.0v actually wears your cells out faster.
If you really want to learn how to treat LiPo batteries, go read some RC forums. Electric RC cars and planes have switched almost entirely to lithium chemistry, rather than nickel batteries. Since RC guys have to use generic chargers (the chargers aren't matched to the batteries like they are in cell phones and computers), they have to spend time learning how to properly charge and maintain their cells.
In fact, I had to take a training class from my model airplane club before I could use the club's airfield, due to the danger of fire if you mistreat a LiPo.

Not really, Other than with NiCd batteries, this has never been a problem with rechargable batteries. In fact, daily charging is the best way to manage your battery.
And that "deep discharge" app? Kill it with fire. That's the best way to ruin an LiPo cell.
