Is it possible to ruin my phone's battery due to overcharging? I charge my phone overnight no matter what percentage it is on, I still charge it I know this is bad, but can this ruin the battery? thanks
You should be able to charge as long as you want w no problems as long as you're doing this in a cool or room-temp environment (rather than say leaving it alone in a car charging at high noon w AC off, windows down & no sun shades on the windshield). If you have your phone charging in hi-temp conditions too long\often your battery swells & you get gradual irreparable damage.

If u make a correct use of your battery it won't get damaged. Extreme overclock, overvolt, etc can ruin your battery, but if u charge it every day because ur battery is empty it's ok, and u won't have any problem.

thanks man =) thanks to the both of you who replied
Normally, when your phone reaches 100 % full battery level, it stops charging and starts discharging. At around 95 % level, it starts charging again. This all takes a toll on the battery, especially over a long period.
If your phone's battery is at or above 50%, leave it alone or turn it off for the night.
I have an external battery pack for use during the day time, just for situations like this.

I don't think that's correct. It should switch to a trickle charge, which won't harm the battery, not stop charging completely.

What I spend a lot of time charging the phone through USB? I leave it on charge at work plugged into the computer through USB as there are no free plug sockets. My battery just seems to be getting worse and worse over the last couple of months... Could this be the problem?

It'll automatically stop charging itself when it's full, it's impossible to overcharge a modern cell phone battery these days. They are a bit more computerized than the old nicad batteries from back in the day. It's actually healthier to give lithium batteries partial charges at a time instead of draining to zero percent and charging to 100 percent.

I doubt it. Could be a faulty battery, but more likely to be apps draining it in the background. Install BetterBatteryStats and see what is using the battery.

i'm using app called full battery & theft alarm. i always charge my phone during sleep, and this app will wake me up to disconnect the charger if the battery is full.
i hope this will prolong the battery life
How do you know your battery is getting worse if it's always charging?
My personal experience is the less you charge it, the better it will perform. However, when you DO charge it, make sure you are less than 30% battery and charge it to 100% before removing it.
For me it's easy, I basically charge my phone at night when I go to bed and that's it. I easily get through an entire day on this phone, though I admit I usually only have about 2-1/2 hours screen on time (I mostly use my tablet when I am at home)
I generally try not to charge my note 2 overnight. I want this battery to be healthy as long as possible, so I don't want it to sit at high voltages for too long.
Normally my note 2 is around 80 percent when I go to sleep so I don't plug it in at night, I just plug it in in the morning for an hour before going to work. It reaches 100 and then I remove it.
The times when my battery is much lower that I won't be able to charge it in the morning in the hour, I do charge it overnight.
What I've noticed is that the battery drains much slower on the days it's been on the charger overnight.
So I'm thinking that the charger will continue to raise the voltage even after it reaches 100%. Maybe someone has some other thoughts, but I just wanted to share what I've noticed so people are careful with their battery.
Hi,
Charge it yhe way you want. Don't stress on it.
But for a few tips:
Don't let the lithium-ion battery go down to critical battery levels before charge.
Don't put the battery on the refrigerator.
Don't over charge it even if it's a new battery .

You can but can potentially damage the battery. It's up to you.
I'm going to disagree with you guys. The charger and the battery has overcharging protection built in. So don't speculate with overcharging overnight. In fact when the phone has stayed longer on the charger I got better battery life. Cheers

Yes, I know. So why would you charge your phone overnight? So it would stay 100% when you wake up?
I charge my phone overnight everyday.
The battery magnet would trigger the charger into trickle mode. This prevents overcharging.
Li-ion battery prefers to be charged then discharged. Contrary to hearsays, discharging it to critical levels too often would actually degrade battery life.
My Nexus one of 2 years still maintained a 84% charge because of this.

The battery have both overcharging and undercharging protection.
So there is no problem charging your phone overnight, the battery will stop charging when it is full. It will then be allowed to discharge a bit and the charging cycle will resume. The fluctuations caused by this charge/discharge cycle are usually hidden by the firmware so that you only see 100% - charged.
As for undercharging, it can indeed kill batteries, but it won't happen unless you drain the battery completely *and* let it self-discharge for a few weeks.
You don't have to adopt a specific charging pattern to keep your battery in good shape, just do what's most convenient for you.
Some tips however :
- Avoid high temperatures, batteries don't like it. The fridge is actually a good place to store your batteries provided that you took the necessary steps to prevent condensation.
- Store unused Li-Ion batteries at about 50% charge. Fully charged batteries have a lower shelf life, the 50% are there to prevent self-discharge from causing undercharging.
- A full discharge-charge cycle won't make your battery healthier but it is useful to recalibrate the power gauge.

I see. Well, in your case it may be better.
Because during the night it gets more time to detect the proper voltage and stop.
And the battery is removable for a reason. It'll have over 80% original capacity even after 2000 discharges and it's only $20 at most to replace. No need to stress it over. Use it all you want and replace it the time comes. Leave the stressing over to the non-replaceable guys.

You telling me if i charge once a day, the battery will still have over 80% charge after 6 years of years? I find that hard to believe as all my previous batteries have to be replaced after 2 to 3 years of use.
That's the quote from manufacturers under ideal conditions. The only devices that I haven't threw out for that long are laptops and the battery in them are still working flawlessly and holds a reasonable charge.
Even tiny LSD batteries can have up to 1000 charges so higher capacity ones will last longer and be more durable due to the increased amount of cells. Just like how higher capacity nand will last longer than lower ones.

If you do it to often it will shorten the battery life
wait till it asks You to charge , I guess that message is for this . Connect your charger ! under 15% Phone tells You itself

Charge at 50% and you can do it about 1500 times.
Charge at 20% and you can do it about 700 times.

I hope you dont do that for all your phones as it will destroy your battery way sooner. Charge it when it reaches 50% and you can do 3 to 5 years with the battery at 24/7 use. (Instead of the 1 to 2 years when draining the battery).
Yes, it is recommended to charge the battery when it below 40% and disconnect the charger when it reach 99%. Do not overchange.
There was a big test I did read and the best was to keep it between 40 and 80 percent.

charge it when it prompts you to charge. at 19% you start getting the first recommendation in lockscreen, then at 15% you even get an annoying prompt.

Are you guys seriously sitting and watching until the battery goes down to certain percentage? And for what? Battery is easy to replace and not that expensive, it has a circuit to protect it from over and under charging, to avoid the damage and you get many more shallow charge/discharge cycles than deep ones as already mentioned. I charge my phone daily in the evening at my convenience, usually before I go sleep regardless of what's left (unless I use it so much it can't last until evening), so by the time I go sleep it's 100% and by morning it will be around 97% and normally last me whole day. I've been doing this for yrs and for example my 4yr old Nokia I gave to my friend, still lasts him couple days of light use on original battery. I wouldn't worry about it at all. Every few months you may want to fully discharge it to lets say 3-5% to have the meter calibrated and maybe clean the contacts with alcohol every six months or so, but that's all the maintenance my battery will get or need. If it fails before the phone, it probably had some factory defect or something, but no big deal as long as there is replacement easy to buy and with so many millions of notes sold, there should be.

Couldn't agree more, I charge mine on a evening regardless and phone gets me easily through a day. If I notice a massive drop in the battery not holding a charge then I will buy a new one. More important things to worry about in life than watching my percentage for the battery.

That is good as a principle but the numbers are still rather big and depend even more on the charging current - if you charge (even) from 50% with 2000 mAh it will never last 1500 recharges - that is why Samsung has slightly improved the Note 3 recharging algorithm so as to use (variable) lower currents (even if the charger is 2000 mAh), and also why it is still far, far better to recharge from a very good USB at under 500 mAh (actually 450) - and indeed preferably from over 40%.

As long as the charging current is lower then 1C (1 full charge for the note3 its 3200mAh) its not a problem and wont shorten lifetime.
But yeah charging at lower currents is better, but more due to less heat and induction.
Anyway its just sad that other people with little to no knowledge about lithium batterys are giving advice, and WRONG advice at that.
Just read the link i posted in previous post (page1) there are the facts. Dont believe just anybody, people are stupid. (yeah im people too )
The chemical reaction will be less when battery is drained and is hard to recover.
But if the battery seems dead, put it in the freezer for 2 or 3 hours and it will be recoverable.
Theres more to these batterys than people think.
Hi.
When i go to sleep after a normal day my battery is around 60%
Yesterday it was only 85% after a full day of usage.
I sleep around 4 - 5 hours at night. That is how long i charge my phone, its allways charging when i sleep.
But is it bad if my phone is charging for so long even if my battery was not complete empty ?

wow. That's great battery. I also usually charge my phone overnight, but I have <10% when I charged it.
I think it will damage the battery somehow, but I can't confirm this, many people have better battery knowledge rather than me, so just wait them to answer it.
But I wanna give suggestions, if your full day use is just consume max 40% batt, just put it in flight mode or turn it off overnight, so you still have enough juice for the next day.
I think it's more battery friendly rather than charge it overnight while still have alot juice in it.
I think it's better to put it in ultra power saving mode instead so you won't miss any important calls or texts.
It is lithium, replaceable battery. Either enjoy it fully charged or buy spare battery and craddle/charger to replace dead one when needed. It only will last so long and you may need replacement in about 2 years anyway.

no its fine. if you want to increase charging time get a Qi charger which takes 5 hours to charge anyway.
Not much to worry about when the battery is user replaceable. You'll be fine, but even if you're not, you can get a brand new OEM battery for 30-35 USD.
No it isnt.. I have 3 years old galaxy s3 i have been always charging it overnight.. Still no issue.. Working good

Just got my OP5 in hand, how long does it need to charge the phone for the very 1st time? As Dash charge can charge the phone to 100% in 30min, do I still need to keep the phone on charge for an extended period of time like b4? Cheers
Hi,
Dash charge can not charge the phone to 100% in 30min
In 30 min you can charge between 40% and 60% depending on what is running on your phone :

Hey,
I don't know definitively but I don't think so. I think battery technology in this respect has moved a long way so you don't have to charge it to full before you first use it, nevermind charging it to full and then over charging for multiple hours.
In fact, phones these days cut off charging and then trickle charge when the battery is full to maintain charge but not try and charge an already full battery thus causing damage.
Bottom line is I would suggest you wait till it gets to 100% before using it but don't need to wait any longer after that.

With modern Lithium ION/POL batteries this is no longer a requirement. In fact the hardware will make it stop from overcharging or it could become a hazard. In fact, Li-ION batteries are best kept between 20% and 80% for longevity. if you plan to store Lithium batteries store them at around 50% charge. so your old phone keep it stored at around 50%. this is also how all laptops and phones are shipped these days. They are shipped with approximately 50% battery charge for any hazard and also for longevity should it have to be stored for a long period of time.
