When and how do you charge your M8?

[mbcastle]

I charge overnight too, but every other night as it takes that long to get below 30 percent.

I just leave mine in the car charger all the time unless I
leave the truck. Since lithium batteries it's not even something I worry about. The last phone I had that even had a battery issue was a Touch Pro 2. Defective battery caught fire while it was off the charger. I don't even remember the last time I needed to replace a phone or battery because it was getting old and losing its ability to hold a charge. They're long gone before it ever reaches that point.

When it is less than 20% or if I won't be near power for over 10-12 hours or so.

You know, I just realized something. The battery in the m8 is not a lithium ion but a lithium polymer. Just though I would bring that to everyone's attention.

Is it better than the lith ion?

Lithium ion is:
Higher in energy density.
Cheaper to manufacture.
But:
Heavier.
More rigid in shapes and styles.
More internal resistance, for slower discharging, and lower amperages.
Has greater aging, even if not used for 1 year.
More explosive, so requires an IC circuit.

Lithium polymer is:
Lighter.
Moulderble, and flatter shapes.
Less internal resistance for faster discharging and higher amperages, at up to 65C continuously, or 135C in bursts!!!
By comparison, a typical RCR chemistry 18650 can only discharge at up to 5.8 amps.
While an IMR chemistry 18650 at 2000 mAH will discharge at up to 10 amps, though an IMR chemistry 18650 at a puny 1600 mAH can discharge at up to 15C, but for the diminished capacity.
Has less self aging, even if not used.
Less explosive, so no IC circuit required.
But:
Less energy density.
Expensive to manufacture.


Thus, LiPo is used in radio controlled cars for their lighter weight and faster discharge rates, for massive amperages, for more power.
LiPo is used in mobile phones especially for their flatter shape, and their lighter weight.
While Lion is used in flashlights for their greater energy density for longer run times.

I don't know if it's better, it's just a different battery chemistry

Charge it whenever I can

I charge my phone during the day while at work, that way I can monitor once it hit's 100%, then I take it off the charge.

I almost NEVER charge while I sleep at night.. it's not really good to leave your device plugged in for very long periods once it hits 100%. Charge it up, once it hits 100%, leave it for a few mins and unplug. You'll get the longest battery longevity using this method.

It's absolutely fine to keep your phone plugged in for long periods of time once it reaches 100%. The phone monitors charging levels and trickle charges it keeping it topped off. It cannot ever overcharge the battery cell. I (and many others) have been doing this with every single phone I've ever had and haven't had a single battery fail me. You can do whatever you want, but it's definitely NOT going to affect battery life leaving it plugged in for long periods of time once it reaches 100%

Hummm. Wonder what that means. I've been following the golden rule of not allowing it to fall below 15%.

I charge mine each night. It's usually around 20% when I go to bed.

It's just a different battery chemistry. You can still charge the same way you would charge a li-ion

I'm talking about battery longevity. I've read many whitepapers on lithium ion batteries, and if you want your battery to last the longest, charge it from between 30% or so to 95-98%.

Charging Lithium-Ion Batteries ?€“ Battery University

Li-ion does not need to be fully charged, as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge, because high voltages stresses the battery.

For the average user who replaces their phone every 6m-1yr, sure, leave in at 100%, who cares.. for me, I like my stuff to last because I'm OC about it.

I read your first link, and it doesn't say anything about NOT leaving a battery charging overnight. I was concerned about this very thing a couple of years ago, and did some research, and came to the same conclusion as Skyway, "It's absolutely fine to keep your phone plugged in for long periods of time once it reaches 100%" The software in our advanced smartphones simply stops the phone from overcharging. How hard is that to understand? Leaving a cell phone charging overnight might have been a factor years ago, but is complete nonsense now. Not to mention that it's nice to have a fully charged phone in the morning

It's on the second link, and here you go for even further info and they include references from Battery University also.

How Often Should I Charge My Gadget's Battery to Prolong Its Lifespan?

Don't leave it fully charged. Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. When possible, keep it in that range to prolong its life as long as you can. And, if you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health. If you need to charge it overnight, use something like the Belkin Conserve Socket to stop it from charging after it's full.

I charge it each morning at work until 100% and then usually once on the weekend, usually Sunday during the day. Between charges I'm using my phone frequently during the day for most of a day streaming music, acting as a mobile hotspot, taking a few photos, browsing the web, etc., and it still have anywhere from 30 to 40% remaining the next day.

I'm amazed that even after unplugging it after it's morning charge I don't have to worry about streaming music or hotspotting with it, it's never been at risk of running out of power before the next workday charge. With prior phones I would have to leave them plugged in if doing either of those things for any length of time, but no worries with the M8. I'm loving the battery life!

 

[alyled]

I charge it when it's very low but plugging it into the wall. It takes forever to charge using my work pc.

The batteries in the m8 are lithium polymer, not lithium ion.

When? Usually when I go to sleep.

How? By plugging in the Micro USB cable into the Micro USB port on the bottom of the phone.

 

[iamstillvince]

I usually charge when the battery is below 80% and NEVER leave my phone plugged in for more than 10 minutes or so once the charge is brought up to 100%. I never charge overnight.

i hope you are joking, you are letting your battery rule your life! throw a backup battery in your pack/car whatever and use your phone freely. I rarely ever need a day charge so it just plugs in at bedtime every day. Also have a cord by my couch and in car if i ever need it.
