Another reason to choose a phone with removable back cover..

I would suspect that most phones now should be able to stop charging at or near 100%. As was said here, the biggest cause of battery depletion is extreme temperature. Extreme temperatures for a long period of time or an incredibly rapid increase or change in temperature.

What! There was a research article into smart phone battery by a university (don't no which) that said; to make your battery last longer, let it deplete fully (to 0%) and only charge 80-90% never 100%. The article and this guy is right to say that you should never keep your phone plugged longer than its needed for your phone to charge.

Best thing to do is buy phones with replaceable batteries. That is why I prefer Samsung over htc or crapple.

Another tip is don't leave your battery in extremely hot or cold weather. IE a hot car on a summer day will ruin the cells inside.

2 years? How bout after 4-5 months your battery starts it's downward spiral

This was a nice video even all these years later

These tools seem extremely good. Do you ship unit items? For prolonged battery life Chargie stick changes everything.

"Never leave it plugged in and charged to capacity for an extended amount of time" Does this rule apply to laptop batteries as well? I.e. for my macbook pro

[mleslie]

It definitely doesn't take 2 Years. A few months you'll notice the difference

I call bull on leaving it plugged in. They have a charge controller that will not let it ever overcharge. You can leave it plugged in forever and all it will do is go down to 97% charge then it will charge a little back up until 100%. It is fine to leave plugged in for long times but draining it down to 0 does cause a full charge cycle once charged back up. Less drainage results in less charges cycles over time.

When fully charged phone dies after hour of gaming
Is that a good sign that I need new battery?

[jessicadomingo]

Do I need to change, my phone shows charging by my batterry not increasing

[johannasantos]

so if i have bulged up battery does that mean that there is no chance it can function again?

[musicman]

My battery is over 2 years old. I definitely need a new one.

[mariabunn]

I've only had mine for a year and its not working anymore

My cell phone I presumed already has factory setting to detect low battery power. Therefore if I did inadvertently reach at a "0%" juice then my cell phone would prompt me and indicate, " slow charge" or change to the correct charger cable. Some other warning similar to it.

The battery is good, not the same though. Factory setting, not that much. Battery will charge on your phone, but not the same way. Stop and charge up on point, once you predict or see that you've reach below this mark. Zero < 30% battery power left. Stay above 30 > though to avoid the batteries reserve warning.

I noticed that my phone charged at a higher rate just before I reach 30% hurdle or mark. If I paid attention.

Sadly, charging below 30% reserve, forced me to charge it up (slow), I would then overlook the, " slow charging" or the "incorrect charger cable" prompts by powering off.

The battery will charge quicker. Either way I had to eventually replace the battery. Less of a hussle that way.

That's right Grimlock1973, I'm looking at you.

[JeremyWhy]

My battery died TWICE while watching this.

I think I night need a new one. Lol

Not so sure on the Not letting it drain to 0%, after 1 and 1/2 it lasts almost as long as when it was new and most of the times I leave it to drain until 1-2-3%, Samsung battery btw.
