I was wondering whether charging our "Smartphones" for about half an hour or more after it hits 100% really makes the battery last longer and increase its life?I charge my phone daily from about 1-2% to 100% and about 20 to 30 mins even after that and I could say that I have found some improvement in the backup time as it lasts longer.but that's just me..so did anyone else find anything like this or in the worst case,is trickle charging dangerous?just curious

You'll see that even after 100%, the battery is still charging.
Trickle charging is that you keep on charging the battery even after it's full. Is that what you asked?
But anyway, from what I've read over the internet, there are mixed views on that. It confused me as well.
Here's a bit of reading for you -
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
There's some info on charging on that page.
I would be more concerned of the effects of discharging your battery to such low levels repeatedly if I were you.

Given that the battery's control circuitry will only let the battery take what it needs and the phones charger would likely reach that point at the 100% mark, I'd say charging beyond that is like sitting a small glass in the sink and pouring a full bucket of water into it. Any improvement over the first few weeks is likely to occur regardless of how the battery is charged.
I guess this one thing will always remain a confusion..I read some reviews that said trickle charging was useful and would enhance the battery life,where some said that charger is to be disconnected as soon as it reaches 100%..well what I asked was whether anyone else had any effect, either good or bad, on the battery life after trickle charging the battery.

I thought that if we discharge our battery to about 2% and again charge it to 100 would increase its life as I read it in an article..but after looking at all the physics in the link I guess ima discharge my phone to about 5-10% only.what do u say? Will that do?

The article says that deep discharges are bad for lithium batteries. I think that a 90–95% discharge would be classed as deep. Personally, I try not to let my phone discharge below 40% if I can help it.
Obviously circumstances and therefore access to chargers vary, so you can only do what you are able to

Who's to say that they don't take such factors into account when they set the 0% and 100% points shown on the display?
They may set these points and calibrate the battery's control circuitry such that destruction of the battery would be highly unlikely.
Why would Sony (or any other company selling devices with rechargeable batteries) allow the user to destroy the battery through normal usage?

They are hardly going to hold back 40-50% of a battery's capacity to prolong it's life.
They probably don't expect people to discharge to 1% every single day.
Anyway, I'm not saying the battery will be destroyed. If you read the article I linked, it talks about loss of capacity and the rate it will happen versus discharge depths

Who said anything about 40-50% ?
You seem to be pulling wild and unrealistic numbers out of your arse in an effort to try and rubbish what I am saying,
There is likely circuitry either built into the battery itself or into the phone's charger that controls how it is charged and probably also shuts the phone down before the battery charge reaches levels that will harm the battery (harm includes reducing capacity, not just destroying it). People don't need to be paranoid about charging as they are unlikely to do the battery any harm. People who regularly let the charge level drop to 1-2% probably aren't doing the battery any favours though and I believe they would be better served taking the time to charge it before that point (such as over night) to avoid being caught with a flat battery when they need the phone most urgently.

So you're agreeing with the point I was originally trying to make before you decided to quote and argue with me then? Good good
And yes, 40-50% was an unrealistic figure, but the point I was making still stands. I am fully aware that they reserve enough capacity to stop damage, but I doubt it is at the level of 40% which is the level I stated I personally let the phone discharge to in the post you argued against.
As for the distinction between harm and destruction, you are the only one that used the terms "destroy" and "destruction". I had mentioned neither before your input.
In any case, you seem to be suggesting that the safety features on modern batteries will prevent loss of capacity. You have used a smartphone for more than a year then? If you had, you will know that loss of capacity is an inevitability that can only be delayed through precautions, but never totally prevented.

Does anyone even charge like this?How many hours does your battery last until it hits 40% with moderate usage?

Firstly, why even come here and ask the question if you're going to completely ignore anything you are told and just continue doing what you were already doing? Looking for validation and wanting to ignore anything else?
It's not like I just made up the information I gave to you. They have tested and proven it. You would have seen that if you had actually read through the page I linked you to, which you obviously have not as you are insisting that the number of charge cycles is the only factor that matters.
As for how much use I get, my battery is holding up pretty well -

Plus, I feel I need to add this -
I NEVER said anything about batteries getting destroyed. Anyone with reading comprehension will see that Nameless One did. Not me.

Ummm, what you're doing is reducing your battery cycles drastically. On the links shared previously, (batteryuniversity website), you can see that for Li-ion batteries, a partial charge is always better, while deep discharging reduces the recharge cycles by a lot (even more than half).
Li-ion batteries are designed for a 4.2V rating, i.e. the maximum safe voltage for acceptable life and maximum capacity (mAh). But the best battery life occurs at a voltage of 3.92V.
So a better option is to keep your battery charge between, say, 40-85%.
And there's no trickle charging for Li-ion batteries these days. The current its automatically cut off after it reaches the desired voltage.
And btw, these percentages are based on the battery voltage, and circuitry in modern batteries limit the minimum and maximum voltage within a safe range, i.e. the 100% & 0% (i'm not exactly sure about the 0%) for the consumer.

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".

I just wanna ask when is the right time to charge?
Do I need to wait until my battery drains or should I charge when at a certain batt percentage?
Thanks a lot
Nope, charge it when you want too.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
there is a site out there (Battery University) I think who did some testing along these lines. The general gist of their findings was that Lithium polymer/ion batteries like that used in the Note do not suffer any sort of "memory" that NiMH batteries used to suffer (the origin of the "discharge fully before charging" advice) however there was a noticeable and VERY gradual decline over time due to the repeated expansion and contraction of the anode (I think it's that way round) and the lowest decline was when the battery was repeatedly charged when it had reached 60% (40% discharge).
tl;dr version: Lithium batteries have no charge memory so you can charge it whenever you want, however you may find the battery could last longer if you charge every night.
Even so, the battery should last you at least a couple of years before you start to notice any changes. Even then, the huge capacity will mean you may not even notice any changes for a further while!

The post "charge when you need it" is most appropriate, and i would go further and say charge the phone every time you are near a charger and will be there for an hour or more.. after all, its not as if the Note is like a Blackberry and can last a couple of days... lol..
As LordManhattan said, you can whenever you want.
Frequent charging would not affect battey life in long run.
But charging from 1% to 100% will.
Personally I don't let my battery go down below 25% (time to swap batteries) and don't charge it beyond 95%.
You may have heard about 'battery life extender' by Ezekeel.
keeping battery charge levels between 20-80% will allow your battery to maintain its maximum capacity.
drain the battery to 0% and you might find it dies just that little bit quicker the next day.
likewise, you know when charging the progress slows down around 90-100%? - that's the battery inefficiency around the max mark; this is damaging the battery too.
so, is there an app out there that will stop charging the battery when we get to 90%?
tasker can recognise the battery level but it has no action to stop the charging so presume ably its too low level. its also not available in the secure settings add on.
Do you have any links to back up these claims?

Some kernels have these options. Battery life extender, where you can change the maximum charging level. I would guess though that by the time you're really affecting your battery life it will be time to upgrade anyway!

Thanks. I'll look into that. I'd probably leave it at 90% or 95% but 80% is the value I heard. Personnally I find charge doesn't really slow down until 98%.
Mugen batteries can be upto $100 each so I think it's worth protecting the investment and Lithium batteries are the same technology in the brand new Galaxy3 or iPhone4s than it is in a GalaxyS1 etc. So that's my motive.
I experience this too! when my phone are only charged at 90 percent it last more longer !

Here's a technical explanation for why this kind of app needs to exist (and why I was Googling this charge-limiting idea tonight to find this thread):
jago25_98 brushed the surface of it in an earlier post, but was blown off. He's dead-on. The top 90-100% of a battery's capacity is very slightly damaging to the battery, which likes to stay in the 3.7-4.0V range (about 30% to 90%). 4.0v to 4.1v is about 90 to 100%, and 4.1v to 4.2v is "you can cram in about 5% more at your own risk" territory. The charge lingers around the 100% mark to cram more power in without exceeding 4.2v. This is why devices are shipped half-charged, not full-charged: the batteries are manufactured at a stable mid-range voltage and charge level. Then, they're tested and returned to that half-charged state for storage (!) and shipping. They like to stay in the middle, not the extreme ends (and definitely not fully discharged).
Charge algorithms are designed solely with capacity in mind, because not much care is put into "how long" something will last. They'd much rather abuse the battery and have the battery (or the device) replaced, than to put a larger battery in to make up for lost capacity by charging only to 80%.
For some of us, we understand that, and we'd like to limit our battery charge so the life of the battery (the capacity it will hold over time) will stand up to the test of time. If treated right, these batteries could last over 10 years. Charging to 100% each day and staying there all night (most of the time, it charges within an hour, leaving it sitting about a quarter of its life at a full charge) is pretty destructive, compared to using an app that caps it at 80% each night, saving the full cycles for monthly battery-meter refreshes.
If it can be done, I'd like to know... I might just dust off my SDK and crack open a "how-to" book to get started. About time I had a good app idea...

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.

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.
Good to know. Glad batteries aren't as finicky as they used to be.

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...
Acc. To motorola cust. Care

SO i contacted motorola through help and they warned me to not charge my phone overnight every night because it would "DRAIN" my battery.
however they said it was ok occasionally
that's a bummer cos it is pretty convenient :/

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.
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.

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?
I do a backflip spin 360 before charging my phone...

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.

Smart alecks. Granted, I got a chuckle.
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.

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.
