[Q] Any disadvantages of frequent charging?

Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?

Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..

True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.

Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.

As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.

Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.

frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....

FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

use it fully untill it drains completely, then charge it to 100% , then use it fully 2 or 3 times and fully charge it.
then just use it like normal and charge like normal

Please do not follow this advice. This used to be the best way to stop NiCad batteried from developing low capacity 'crystal memory' but it is not the case with LiOn or LiPo batteries, in fact, quite the opposite. Doing as he recommends is much more likely to damage the battery and even start a fire.
A LiPo shouldn't be discharged by more than 80% if at all possible. If you want to know more there are a lot of links on the interweb but here's a typical thread on stack exchange .. and a quote from it ...
http://android.stackexchange.com/qu...-first-time-charging-on-li-ion-batteries-myth
Nowadays, batteries are often Lithium-Ion or Lithium-Polymer and such batteries (as I have read many times and based on my own experience) would be stronger if you charge them often. The first time charging and "wait-until-full-discharge-before-recharge" and "don't-use-when-charging" are not applicable to these modern batteries.
Li-Ion and Li-Polymer batteries, if charged often, after about 1 month, would reach to their maximum performance, and you are recommended to charge them every time you find an outlet!

Wow, now we have the Richard Dawkins of battery advice. Well done.
Can everybody just calm the funk down and charge their batteries as and when they see fit? It's fine. Either way.
There is circuitry inside the battery that will prevent them from over charging, under charging, over discharging catching fire and generally behaving badly. There is also no memory effect. Just charge them when you think you'll need them.

Yeah just keep using it, if one day in the distant or not-so-distant future it doesn't turn on for some reason and/or seems unresponsive, it might need charging.

Hmmm .. shows how out of date I can get ... I didn't realise that the overcharge protection had reached such a state of sophistication ... Personally I never bothered with battery regimes, even in the bad old NiCad days ...
Thanks for the correction.

The overcharging prevention was first introduced to the Sensation and EVO 3D phones. I remember when I started seeing it because I would leave for work, and sometimes my battery wasn't charged fully. What it was doing was charging to 100%, then stops charging and will let it discharge 5%, then start charging again. And it would keep doing it until I took it off the charger. I've yet to see my EVO 4G LTE do that, though. Maybe it's been refined so that we don't notice it as much?

On the note of over-discharging: just because there is circuitry inside the battery to prevent over-discharging doesn't mean you should ever let your phone run down to (what your battery shows as) 0%. Yes, the phone will generally shut off when the battery is left at around 3v, but it's still possible to force turn your phone on (which you should never do) after that point. Not to mention, leaving the battery at a low voltage for a significant period of time WILL affect the overall lifespan of the battery. Battery manufacturers will do what they can, but there is really no such thing as "true" over-discharge protection, as with overcharge protection, since batteries will still lose charge even when not in service.
Yes, if you let your battery run down to (what your phone shows) 0% occassionally, that is OK. But you should really only be doing that if and only if you need to re-calibrate for cell mismatches.

Hah! I still remember when I bought a mugen battery the instruction clearly says to discharge it fully and charge it fully for like 5 times to get optimum capacity Obviously I didn't do it. I am much aware of these things since good old Nokia 3310 days.

will the battery be ruined if phone is constantly plugged in?

i'm currently using my note 1 as a secondary monitor and it is plugged into the standard charger while doing so. Will the battery be constantly 'zapped' as I use it? or the battery can remain 'like new' if it's always plugged into AC?
Thanks!

Might be,might be not. I did that sometime, even on my laptops without any problems. But the recommended is unplug when it full charged and charg when its 1-10%. I use battery doctor app for trickle charge for long live battery. And btw the OEM stock bettery is cheap anyway. From now till ur battery is getting drain like hell its would be take like 6month to a year.

It's better to discharge it completely, then recharge it completely from time to time.

Full cycles of charging and discharging keeps the battery healthy for a considerable time.

Also, keeping the phone on charging even after it hits 100% causes the battery to swell. You will not see the effects immediately, but after 4 months, the battery will be swollen on one side. And swollen batteries like to self destruct.

Every battery can be recharged several times[for exm: 500] If you charge it 5 times per day = 100 days battery life. So i think its better to dont remove adapter when battery hit 100%. The new cell phones and laptops got protection and they dont charge the battery when its fully recharged.
This is just my opinion.

Some time ago I did a little research, because I was using my phone as a wi-fi modem for my laptop. Most opinions said, that constant plugging may affect your battery life and best is not to keep it plugged when fully charge too often and for too long.

no it actually does not cause this... the batteries and phones have smart circuitry which prevents battery overcharging.
now fully cycling a battery 1-2 times a week will extend the life of the battery..

As far as I remember from the tech-news, newest energy cells (li-ion and li-poli) shouldn't be charged like the old ones - I mean charge 12h, then empty it completely and repeate the whole process 3 times. I read it on polish site some time ago and they we're also saying, that keeping phone under chargerer can harm battery or even mainboard.
But as we can all see, there are many different opinions about that

Mine did. Swelled a bit on the side, cover used to creak whenever I pressed on the other side

All (reputed) devices that use Li-Ion batteries use controllers that will automatically cutoff charging once the voltage reaches 4.200V/cell.
So you cannot over charge a battery by leaving it on for long duration.
Unlike the older Ni-Cad batteries, there is no memory effect. so there is no need to fully discharge it periodically
In fact, deep discharge of Li-Ion battery will irreversibly reduce battery capacity (Wikipedia -> Li-Ion battery -> Battery life )

[Q] Overnight charging recomended by Motorola?

I just got a "tip" from Motorola telling me that its best to charge my phone to 100% whenever I'm near an outlet and that they RECOMMEND charging the phone overnight to accomplish this. Are they trying to make my battery die quicker or something? Am I missing something about newer cell phone batteries that allow for constant recharging over the course of a single night without killing the battery?

Apparently, you can charge some of the newer phones and tablets overnight and not have to worry about overcharging. These newer batteries are supposedly able to stop taking charge once they reach full capacity. I've Google'd this a few days ago and several users on several forums from different sites are all saying the same thing. However, although you can charge it overnight without having to worry about overcharging, heat conduction while having the battery charge might be excessive enough to damage the battery.

I leave the phone on charger all night every night and i haven't really noticed any changes in battery.

I've always left every single one of my phones to charge overnight. Do some people really take it off the charger as soon as it's charged? That seems like a waste to me, as you're using battery charge that you could otherwise be using throughout the day.

That Motorola tip is total BS. It doesn't matter whether you charge it to 100% and you certainly don't need to charge it overnight to accomplish that although it's fine if you do.

I think the newer batteries today become worse based on the number of cycles you put them through. Further, letting your phone only go donw to 80% before charging it back up again causes less strain on the battery and isn't a full cycle. The more cycles your phone goes through the less of a charge it can hold. This is why many people report to charge your phone as much as possible because it is actually better for you to leave it charging all the time instead of doing a battery cycle.
Many battery monitor softwares require you to recalibrate the batteries capacity to hold a charge after a certain number (often 30) cycle have been performed. And they consider cycles depleting your battery pass a certain percentage (ex. 70% or something). I did a decent bit of research a while ago and this was the information that I gathered from all of it.

Right. It is better to charge your phone as much as possible because your battery is capable of only a finite number of full cycles. My only contention is that it is not required that you charge it to the full 100%. In fact, they say that it's actually better for Lithium-ion batteries to hold partial charges.

Never charging the battery to 100%, nor depleting it to 0% will allow you to more get more out the battery overall. But keeping it on a charger means that you shouldn't even be using the battery.
I keep mine on charge overnight, and if I weren't worried about wearing out the USB port, I'd put it on a charger when in the car, while at my desk at work, etc...

Sorry but whoever told you that is misinformed. No harm will come to the phone / battery from charging overnight unless you use a dodgy fake charger. I've charged all my phones overnight since my Motorola MicroTac in 1995 and have never had a battery / phone fail because of it.

All Motorola devices have good battery protection software, it won't hurt it to charge overnight. Short charging sessions are better for your battery but it makes no sense to worry about that either. The only way to hurt your battery is if you stuff a charge by letting it fill, then unplugging an plug it in several times. This can "top off" your battery and give you a little more charge but at the risk of damage and shortening your battery life. I personally don't recommend it. I have Anker backup battery if things get desperate or if I am out all day.

Well yeah, how about Apple doing it and everyone else pursuing? prolonged charging IS damaging your battery. If you use a Chargie device (https://chargie.org) during your overnight charging you might prevent this, since it delays and limits the charging pattern to a safe value. But otherwise nobody in 2021 recommends leaving your phone charging overnight.

I think the battery has overcharging protection, so it won't overcharge and damage it, so leaving it on charger during night, even if the battery reaches full level, is not going to cause harm.
Also, using the phone while it's charging, won't damage the battery.
Useful battery info HERE.

Thanks! I thought may battery is bad. 43% in 3hours the screen was on. XD

Best way to charge:
Quoting from http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries:
Code:
A portable device should be turned off while charging. This allows the battery to reach the threshold voltage unhindered and reflects the correct saturation current responsible to terminate the charge. A parasitic load confuses the charger.
Charge at a moderate temperature. Do not charge below freezing.
Lithium-ion does not need to be fully charged; a partial charge is better.
Chargers use different methods for “ready” indication.
The light signal may not always indicate a full charge.
Discontinue using charger and/or battery if the battery gets excessively warm.
Before prolonged storage, apply some charge to bring the pack to about half charge.
Over-discharged batteries can be “boosted” to life again.
Discard pack if the voltage does not rise to a normal level within a minute while on boost.
