[Q] When should i charge the battery?

hi!
guys, when should i charge the Galaxy S battery to maximize his life?
In my old phone, i only charge it when the phone shuts down himself. It can run for 7 days with no problems until i need to charge again.
Should i do the same thing with Galaxy S battery?
Well, when i need to connect the phone to the PC using USB cable, it will charge anyway. Is it bad? Should i do it only when i know the battery needs to be charged (when it has low battery)?

any time you want
it should always be topped up, there is no memory effect

Some people say that we should charge when the phone has 25% or 30% of the battery. And every month we should make a complete charge and discharge.
Is this a good method to keep the battery ok?

best way is to cycle through 2 or 3 batteries
charge them full
then use them down until you get the warning, and change to new battery pack, then take the used battery to the charger

Although I don't really have any definite sources to back this up, I've read several places that Li-Ion and Li-Polymer batteries can (and even should) be charged as often as possible. You should avoid letting them run flat, apparently.
What is certain though, is that they themselves have no memory effect like NiCd and NiMh batteries have.

our SGS will nag you to death as soon as it reaches 10%, and it will constantly annoys you to charge the battery at 5%
so, no worry about running flat

Technically to maximize the life (ie. capacity) of a Li-ion battery you should charge to full when it gets down to 40%.
The cooler the ambient temperature the better - A Li-ion battery operating at 25 degrees C will lose 20% of its capacity in one year. Higher temperatures drastically increase this degradation.
Given that most people will move to a newer phone after 2 years or so, and spare batteries are cheap as chips, it doesn't make a whole lot of difference.

So, people say that we should charge the battery when it has 30-40% of the capacity.
But what is the thechnical explanation?

that's exactly what i would like to know as well at 30%-40% will make the battery totally useless if that is true
might as well take the phone with a super long extension cold with you if that were true
LMAO

I don't think that would be the best strategy, AFAIK (and read)
Li-ion packs prefer more frequent charges, even if after partial discharges, than full charge-discharge cycles.
Its also not good to store the pack fully charged. Best to store at 40% charge.
Following these 2 concepts, I imagine its better to charge the battery as often as possible, like every day, than to let it discharge until you get the warning.
Also, if you cycle through several packs, letting each one discharge almost completely, then charge it fully and move to a different pack like you suggested, that means you will be letting the battery unused at full charge for a longer period (the more packages you use, the longer the pack will stay stored at full charge).
Thats how I understand the behavior of those batteries. Just my 2 cents.

I will say what the first reply said, charge as often as you feel you have time. Do not wait for any percentage of drain. There is no memory effect and yes about once a month do one full uninterrupted cycle. The point of which is to let the device's power management recalibrate where 0 (or thereabouts and 100% of the current fill are.
Cooler is better, this is also true.
All educated advice on Li-Ion batteries is that they remain healthier for longer the fuller they are, but the chemicals must be exercised occasionally, thus the full charge cycle in one go.
One charge cycle also actually counts over multiple charges, and not just uninterrupted ones. You can drain then charge 25% 4 times and that is counted as one cycle for these batteries.
I have always stuck to this advice since I learnt of it several years back and I find my batteries work better and longer than many people I know (who stick with drain, charge methods (lack of updated information).

i agree with nailerr

Simply charge it when you need to. It's better to have a fully charged battery when you need it, than run out of battery when an important call is coming through

So, the main reason to charge it with 30%-40% left is to avoid the battery heat too much?
I found this: h**p://batterycare.net/en/guide.html
It says more or less what you guys said here.
But you need to know that i always charge from 0% to 100% my old phone. It is 4 years old and it has no problems with the battery. It can run up to 7 days without any charge... Looks like charge it that way is not so bad anyway i guess...

[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".

[Q] Battery Memory

So, I'm nervous about the fact that I can't replace the battery on my ONE. So far every night I've been staying up late until the phone dies, then plugging it in, waiting til the light stops flashing, then powering it up to charge while on overnight.
Problem is, this phone has awesome battery life. Right now at 10.30pm, I'm sitting at 41%, and debating just leaving it unplugged all night.
So what's the deal with memory on these batteries? How much, say over a 2 yr span, will charging a non-drained battery shorten its lifespan or lessen its capacity?

Lithium ion batteries are awesome. They are lighter, smaller and do not suffer from "memory effect."
Do not drain then fully recharge this phone on a regular basis. That will accelerate capacitance loss. Keep it charged as much as possible, avoid fast charging, try to use your PC to charge it overnight. Do not leave it charging for too long (i.e. days on end). Though on board computers can refuse charging, it is best to stay on the safe side.
2 years, you will definitely notice a decrease in battery life, but by the time it becomes intolerable, you will have upgraded. I can almost guarantee that.
EDIT: Please add to/refute any statements I made if you have greater knowledge on this subject, people.

Thanks! Can you explain why using mr PC to charge is better?

As was previously noted, what you're doing is actually the worst possible thing you can do to a lithium ion battery. In general, best practice is to keep your battery somewhere between 10%-95% charge whenever possible. Once a month, you should "cycle" your battery under 10% (but not fully drained) to keep everything in peak condition. If you're ever not going to use the phone for any length of time, best practice is to drain to 40% and store in a cool, dark area.
When you first get a new device, you do want to condition it by doing three to five (varies on the device) full charge/discharge cycles, but after that, once a month with a conditioning cycle will take care of things for you. And again, as was previously noted, it's not a great idea to leave your phone charging overnight because you can't always depend on the battery controller chip.
These newer cells are all rated to relatively high cycle lifetimes, so I wouldn't worry overmuch. At that point, capacity is supposed to start degrading, although naturally it's going to happen a bit earlier for any number of reasons. I'd be much more worried about avoiding heat though than overcharge.

I'm assuming charging it slowly would keep it slightly cooler than a wall socket and closer to room temp, the better.
There is probably some other reason, but I'm not the person to ask. you can do some independent research. :good:
Just charge your phone when it needs it and don't when it doesn't. Do that and you'll be good until you upgrade no problem.
EDIT: Oh, beat me to it... haha
EDIT: Also, does the 40% apply to phones? Mobile devices never really turn off, they just go into deep sleep, I'm told. I was going to say that too, but then I remembered this. Does the 40% rule apply to non-removable batteries?

It's a question of how much voltage you're chucking into the battery. If you use a low-voltage wall adapter it'll be the same as if you were charging from your PC.
The 40% rule applies to any battery, and they'll all discharge over time anyway (connected or no). If you shut your phone off, everything powers down except (if memory serves) what's necessary to run the internal clock. The impact that has should be pretty minimal (unless you're trying to bury your One for a thousand years, in which case...can't help you there).

And yes, I would like to bury my One safely for a thousand years, so when it is found by the generation of humadroids, they will see it and be amazed that a civilization so primitive could achieve such technological mastery.

I don't know that I bought any, but I have a few lying around from yesteryear's gadgetry.
And at that point, why not launch it into space instead, a la HTC Nexus One?

So I use my phone as my alarm clock and also run the Relax and Sleep app all night. Otherwise I'd just plug it into my lappy throughout the day and not worry about it.
But that raises another question: running the phone overnight while charging it at the same time. Bad juju?
I plugged into my lappy last night around midnight, woke up this morning and had about 95% charge, rather than the usual 100%. I'm assuming this is the result of power output for Relax and Sleep cutting int power input from charging.
I've also been in the habit of leaving my EVO 4G plugged in while tethering. I assume this is also a bad plan?

MOST of this advice is 100% true.
The only part that is not correct information is the advice to not let it die. It is perfectly OK to do this as long as you don't deep discharge the battery... Example like let it die then not charge it for like a week or something.
The science behind this is the fact that lithium ion batteries actually have a nominal voltage operating range which is like 3.2 - 4.3 volts or something like that. Your device is designed to shut itself down when it gets to about 3.5... This is done to protect the battery from deep discharge cycles.
Letting it die is perfectly alright. Just make sure you charge it soon after.
Also, you don't need to use your PC to charge it. That is in no way necessary. Your device came with a wall charger for a reason...
There are safety features built into the kernel and cable to keep you from damaging the device during charge. Use the wall.. It is perfectly safe and faster / more practical.

Your battery will automatically cycle between 95%-99.9999% to prevent overcharge, so you're fine on this front. You probably just caught it on the low end of the cycle.
The issue with charging + tethering is that a phone draws more power when plugged in (ramping up processor, etc.), and tethering eats a lot of power. More importantly, both charging the battery and running the antennas for tethering generate a lot of heat. So long as you watch your battery temp (most good tethering apps will toss in a temperature gauge, although if you're using stock you'll need another solution), you should be fine, but heat is one of the fastest ways to kill a Li-ion battery.

Although a full normal discharge (phone powering off) won't kill your battery in one go, it's a deeper discharge than I would recommend on a regular basis. Things are built with margins of safety, but I don't like playing on the edge when I can avoid it. The difference between 10%-15% isn't too much either when it comes to my use-case either, so I'm content to bounce between 20/30-95 most of the time.

About safety margins

Concerning the Nexus 5 battery, how do you recharge your device?

Hi guys, good afternoon, how are you?
As I was looking after the Nexus 5 and the battery life of the device began to get discussed, I was unaware of the fact that nowadays we can just charge the device however we like, using Lithium-ion polymer batteries, different from the past, when a full recharge was recommended for the battery performance not get affected.
Considering that, for some users the battery life shouldn't be a concern, mainly for those who have a power outlet nearby, making an option to recharge it at any % level before getting it to fully recharge during the night.
I'd like to know from you guys: how do you recharge your devices? Do you wait for it to drain every % of the battery before recharging it or just plug it on the power outlet whenever needed?
Also, do you guys believe that recharging it at any % level does not affect battery performance?
Thanks a lot!

Modern batteries have a finite number of charging cycles before they being to lose performance. Generally speaking, 100%-0% is one discharge cycle, so if you want to maximize battery longevity you should do your best to minimize the number of discharge cycles you subject the battery to. It is not strictly speaking a direct relationship, but the battery should last longer if you charge it when it reaches 50% as opposed to 0% (that would qualify as "half" a discharge cycle).
When I'm using my device heavily and I have access to an outlet, I leave it plugged in. That saves on discharge cycles. Also, when I am sitting at my desk at work I generally keep it plugged in.
The following link is an excellent source of information regarding batteries:
http://batteryuniversity.com/learn/

right now with my current phone i'll usually just top it off after work from a wall outlet, or top it off in the morning when i wake up and get ready for work. i also have a usb cable at work to top off whenever needed throughout the day. i try to keep the battery over 50% most of the time, just because, but i rarely leave it plugged in throughout the entire night, and this is even with running sleep tracking apps. i imagine battery use/charging will be the same with the nexus 5 -- topping off in the morning while getting ready for work, maybe charge a bit while at work via usb cable, and topping off after work via wall outlet.
i guess i charge my battery in intervals throughout the day, instead of the daily 8 hour overnight charge. however, i usually keep it at least half full

Plug it in at night before I go to sleep.
If i'm using it heavily and it gets below 50%, I'll plug it in.
Some days at the office I'll plug it in about an hour before I leave so it'll be almost 100% after work.
If i'm going somewhere and feel I may run the battery down before I get home, I'll carry my portable charger with me (Anker 5600mAh).

Wouldn't heavy usage while its charging put too much heat on the battery? Which is worse for it then worrying about charge cycles?

It depends whether/how much heat is generated during heavy usage. On my N7 while browsing the net or watching videos the heat is non-existent. Certain games cause more heat than others. If the device starts to become "hot" then yeah, keeping it plugged in will only exacerbate the problem.
Also, having a case on the device can increase heat soak.
It depends on the situation.
You are right though that heat is the enemy when it comes to batteries. About an hour in my back-back on a beach on Oahu killed my GNex battery, and it was in the shade too.

I plug mine into a wall charger or my laptop...

At the end of the day though, if you don't bake or freeze your phone, the battery should last at least a couple of years without losing too much capacity I think.
The battery longevity discussion with mobile devices is similar to the oil change debate in automotive circles. Some people swear by certain brands and oil change intervals, whilst others just buy what is on sale and change the oil when the car tells them too. It probably makes very little difference in the end.

To OP:
Today's lithium ion batteries are way better than what they were 10 years ago. As posted above, go to battery university and learn all about it. My advice? Don't worry about special ways to charge your phone. You'll break, sell, or permanently store this phone long before your battery gives out due to charge cycles.

This!
Once upon a time I used to wait till my phone drained to 0-5% before I charged it. But I quickly realized that doing so turned my battery into trash.
So now with my 2 latest phones I usually charge it when they are at 30-40% or higher if possible and not only do I get excellent battery time but also its lifespan & performance doesn't deteriorate over time.

The only advice you need: DO NOT FULLY DISCHARGE LI-ION BATTERIES. These aren't NiCads, you do not need to power-cycle them periodically.
For best Li-ion life, try and avoid discharging below 20% or above 80%. Manufacturers will often add some 'headroom' to the 100% level (so that a battery that reads 100% is actually only charged to 80%-90% of capacity) in order to maximise longevity. within that range, charging and discharing will have little effect on battery life. charge and discharge rates do have an effect, but again ythe battery controller will limit these to prevent damage to the battery, so this is not something you need to worry about yourself.
Keep the battery topped up and avoid discharging it completely. Anything else is hocus-pocus or incorrect advice for the wrong battery chemistry.

i replace my phone once a year so i dont bother with saving the battery etc.. ive never had any measurable degradation to the battery the way i charge in less than a year. I usually charge it from what ever % its at to full. Most of the day at work it stays on my wireless charger, but it stops charging it after its full.

Thanks everyone for the feedback this far, in just a couple of minutes I already learned a lot.
Please let's continue the talk and vote if you can!
Thanks again.

On the charger before reaching 10%, around 20% or higher if it's possible.

this +1.
I put emphasis on 'so this is not something you need to worry about yourself'.

Thanks to this two people.
Before i read this, me always charge the @ 10% or below.
+1 :good:

I just discharge to 20%-40%, then charge it with the included charger overnight...
I've tried using slow chargers but didn't really make the battery any better.
I agree that discharging it fully is bad. Very bad.
I just charge it how it's mean to be charged and I don't have any problems

I've been charging wrong this whole time! Will start charging before I hit 10% from now on. Glad I saw this, just got a new phone and am hoping to keep it for as long as possible...

I charge it every night because I have to use it all day.

Turbo Charger on Overnight?

I always charge my phones overnight when I go to bed. Not that it takes that long for a battery to charge, it's just when it's convenient. And I'm sure I'm not the only one who does this.
My question is if the Turbo Charger that comes with the phone will hurt the battery long term if I keep it plugged in all night. Or is is smart enough to shut off and/or lower it's power draw from the wall. I know a lot of people have hypothesized that the battery will have a shorter life cycle with the abuse the Turbo Charger will deliver time and time again.

Can't answer your question specifically, but read where the phone fast charges up until a certain percentage is left. I'm thinking that it fast charges up to 75 or 80%, then reverts to the regular slow charge.

Going forward, a huge number of phones are going to support Snapdragons Quick charge technology, the turbo is not the first nor will it be the last that will have this feature. I am no expert on this, but I HIGHLY doubt that Moto (and all of the other companies that will be supporting this technology) would package a charger with a phone and advertise this feature if it has the possibility of damaging the battery.
I plug my phone in every night like you, personally I am not going to worry about it. I think a lot of people charge their phones when they go to bed as well, I have to imagine the engineers thought this one through.

I'm agree in the part that I highly doubt that companies put harmful accessories with their products, it won't make any sense.

I noted that the phone gets real hot when charging until 80%, and then it starts to cool down, maybe is because of what you said.

I plan on using a regular charger for overnight, and keep my turbo charger at work for my long shifts. Just in case.

I have been using the turbo charger daily since the release. I too have my phone charge overnight with it and haven't encountered any negative effects or problems at all. The phone cools down for me after 60%. This cpu and charger are intelligent in handling the voltage and what not to not harm battery. If it was harmful then qualcomm wouldn't be inputing so much research and tests to have a stable version of quick charge. Keep that in mind too

Been using quick charging for 6 months including plugging in overnight while breaking every rule about charging batteries with no noticeable losses. As stated quick charging only goes at full speed during the first part of the charge, 70 percent is often mentioned. In practice the full charge phase is dependent on battery temp which is monitored per cell and other factors. I recall reading that such charging has a theoretical perfect world capability of charging 1amp in 6 minutes and we are nowhere near that. There is a lot of research and testing in quicker charging methodology and it has been in use in other areas for several years, I'm thinking there isn't much to be concerned over in any aspect of it.
Edit, just an FYI... My Oppo charger works on the Maxx and the Maxx charger works on the Find 7, I get full speed with either charger on either device. I have one of the Verizon car quick chargers and I can confirm it also works on both devices and charges full speed. Nice to know we can do some mix and match on these.
