I would just like to share some of my experiences with a cheap 3$ eBay battery (like this one), as well as ultra-cheap 2$ USB chargers.
I bought this battery early January to supplement my GS3's main battery. At first I used it as a backup battery, keeping it in my bag in case my main battery dies. This worked great for a couple of weeks until I could no longer be bothered to swap out the battery every time I needed to charge the other one. So I ended up leaving the eBay battery in full time. At this point I have grown to trust it, seeing as I hadn't had any issues.
Months went by like this, but by the end of March, I was scratching my head as to why my phone wasn't lasting as long as it used to. I guess this change was so gradual that I didn't notice it for long. Now this past week, the battery has had even more trouble holding a charge. It took hours to recharge, and barely lasted with me listening to music, chatting on fb and checking reddit several times a day. It got to a point where one night, it only charged to 90%, and then the next night it charged up to 45%. It also would only charge a few percent at a time when daydream was on.
Now yesterday, by the time I got home ~16:00, the battery died. I plugged it in, but it wouldn't charge - a battery with a warning symbol icon lit up when plugging it in. After a few minutes of fiddling, I managed to get my phone to turn on, but then it almost immediately turned off. A few minutes more, I managed to turn it on and finally charge using the original charger. After an hour, it didn't even reach 20%. This enraged me, causing me to finally hot swap the battery to the original one. Surprisingly, it charged up to 70% in less than 1 hour. Quite a nice change.
Since this morning I've been using it more than normally (large FTP download, streaming youtube), and I still have 60%
I suspect that the low quality anode within the battery corroded very quickly due to the high stresses involved with powering the phone, and charging rapidly. The thing that I often see online, is people being afraid of batteries blowing up or damaging their phones, but this is highly unlikely. The phone has the battery charging circuit built into it, and it will regulate the CV and CC charging cycles itself. It shuts off the phone when the voltage drops too low, and it wouldn't go over 4.2v because the phone wouldn't charge above that. The only damage that a cheap battery can do is to leak or vent inside a phone - hence the need for proper circuitry in the phone.
I also have experiences using absolutely the cheapest batteries in some of my other gadgets. Both of my cameras use the cheapest batteries I could find on eBay - without any problems. Ironically, for my point and shoot, the eBay batteries last longer and display an accurate time estimate. With my DSLR, the 2 batteries that I bought (originally to make a cheap power supply for long timelapses), they work identically, charge identically and fit perfectly. I also bought some protected 18650 batteries for various LED projects I was working on, as well as for my flashlight, but about half of them are now dead - I suspect due to the protection circuit. So yeah, those are my experiences with ultra cheap batteries.
Now, as per the chargers, I mostly use only el cheapo dealextreme or eBay ones. I've had no issues with charging my old iPhone, my SGS3, tablet, and my el cheapo 20$ Huawei phone. However, they don't work well with my Raspberry Pi, iPad and my mom's Android tablet (the touchscreen glitches big time).
So yeah. I don't know what the purpose of this is. Just had to speak out .
Hey guys I'm often a lurker on here and don't post a whole lot but came across this article and found it interesting. Thought I'd share... Also, I like to leave my HTC ONE plugged in on my desk stand at work with the "Daydream" clock function running (basically using my phone as a desk clock). Do you think leaving it plugged in charging all day running this clock is doing any damage to my battery? It of course fills up and charges to 100% pretty quickly because I never really let it get below 80%. Below is my charging habit...
1. Charges all night at my bedside
2. Take it off the charger in the morning while getting ready for work and my drive
3. Get to work, plug it in for 6-7 hours running Daydream
4. Take it off the charger and go home... (off the charger for about 4-5 hours in the evening)
5. Go to bed, plug it in, and start all over again...
Oh and here's the article :lol:

How To Take Care of Your Smartphone Battery the Right Way
Click to expand...
Click to collapse
Your smartphone is a minor miracle, a pocket-sized computer that can fulfill almost every whim. But none of its superpowers matter a bit if it runs out of juice. With removable batteries becoming more and more rare, you've got to take good care of the one you got. Fortunately, it's not to hard keep the lithium-ion powering your everything machine happy if you follow a few simple rules.
Obviously, the first rule for extending your battery life is not using up all your battery life playing candy crush and walking around with Wi-Fi and GPS enabled when you're not using either and really, really need your phone to last that extra hour. But aside from that, there are some basic rules for care and charging, and they're the simplest baseline for a healthy battery.
Top it off
You may vaguely recall hearing something about rechargeable batteries and the "memory effect." You know, that if you don't "teach" your rechargeable batteries their full potential by taking them from totally full to totally empty, they'll "forget" part of their capacity. Well forget all that. Right now. It's wrong.
To get the most out of a lithium-ion battery, you should try to keep it north of 50 percent as much as possible. For the most part going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often. That said, it's smart to do one full discharge about once a month for "calibration," but don't do it all the time. Running the whole gamut on a regular basis won't make your battery explode or anything, but it will shorten its lifespan.
So if you're really particular about optimizing your battery's life, you should try to go from around 40 percent to around 80 percent in one go, and then back down whenever possible. A bunch of tiny charges isn't as bad as going from 100 down to zero all the time, but it's not optimal either.
Keep it cool
It's easy to worry about bad charging habits thanks to the training we've had from old rechargeable batteries, but lithium-ion batteries have a worse enemy: heat. Your smartphone's battery will degrade much much faster when it's hot, regardless of whether it's being used or just sitting around doing nothing.
At an average temperature of 32 degrees fahrenheit, a lithium-ion battery will lose six percent of its maximum capacity per year. At 77 degrees, that number jumps to 20 percent, and at 104 degrees it's a whopping 35. Sure, it's not exactly practical (or sane) to keep your phone in the fridge, but it's worth going out of your way to prevent long stays in hot cars and the like.
Avoid wireless charging
Wireless charging is can be incredibly convenient if your phone can do it, but it's not without its disadvantages. The inductive, wireless chargers out there today have this nasty habit of generating a fair bit of waste heat. And while wasted energy is just a bummer in general, that heat will also toast your battery in the process. That's no bueno. It's a little less convenient, but standard plug-in charging is going to keep your battery in better shape, especially if you're some place warm to begin with.
Never go to zero
Obviously, using your battery is going to make it degrade. But it's going to slowly die even if you just leave that iPad in the closet for a bit. There's a trick to minimizing that inevitable aging though: leave it a little bit of juice.
If you're going to be shelving any lithium-ion battery for a long time, try to leave it with at least 40 percent battery power to tide it over. Lithium-ion batteries don't hemmorage power at 30 percent a month like nickel-metal-hydride batteries do; they'll lose maybe five to ten percent of their charge each month.
And when lithium-ion batteries get too low—like, literally zero percent—they get seriously unstable, and dangerous to charge. To prevent explosion-type disasters if you do try to charge one, lithium-ion batteries have built-in self-destruct circuits that will disable (read: destroy) the battery for good, if it reaches rock bottom. And sure, that'll save you from a face full of battery-acid, but it'll also leave you short one battery.
Don't sweat it too much
It's easy to get protective of your battery, but it's also easy to get lazy. And that's fine, because as long as you're not a complete idiot, you'll be OK. Typically, a lithium-ion battery lasts for three to five years, and chances are you're going to want to swap out your gadgets sometime in that window anyway. The slight damage of a technically bad idea like leaving your phone plugged in all night every night, or using wireless charging, might be worth the convenience.
Still, it's pretty easy to keep your battery reasonably healthy just by avoiding particularly egregious torture like letting your phone discharge from full to zero every single day, or leaving it in a hot car all the time. And the next time you make it back home with power to spare, you'll thank yourself for it.

I dont agree that your battery dosent like being or performs worse at a 100%. Or that it harms the battery in any way. I keep my phone plugged in as much as possible durring the day, and all night long. But i only use the wall charger that came with the phone, or a smart car charger made for my phone. Because as the article says, these chargers are smart enough to stop charging for awile after the phone has reached 100% to prevent over charging/heating. Cheap wall and car chargers dont have this feature and continuously provide a charge to the phone. Also charging using a usb port on a pc or other device does not provide this overgharge protection.
My last phones battery lasted for almost 3 1/2 years before needing to be replaced. Heres what i do.
Keep it charging as much as possible only with a "smart" charger.
Never let the batter drain all the way down. If it gets to 10% and i cant charge it at the moment, i turn it off.
Never let your device get too hot. Dont leave it in hot cars or sitting in the sun, etc.
Never "bump charge". That is just a way to trick a smart charger into overcharging your battery.
Also over clocking/volting your phone puts more strain on your battery than it was intended to take. It makes its temperatures rise higher, and the charge to deplete in a more rapid fassion. Both of which are bad for your battery.
These are just my opinions of course, but it seems to work out good for me. I think 3 1/2 years is a pretty acceptable life span.
never let it die
I have always left my phone's plugged in constantly and never an issue. Once my phone hits 100% it stops charging and then is very cool to the touch from then on.I heard phone's now has a failsafe that will stop charging and start running the phone off the charger and not battery.

What's the best battery conservative rom?
Why do you think you should never fully drain it?
Every 30-40 days, you should fully drain your battery - until your phone automatically powers down - and then fully charge it - and allow it to stay on the charger for 30-40 minutes after it's 100%.

The battery management system in the phone does not allow the cells to go lower than the safe level. For Li-ion cells, that's somewhere around 2.7-3.0volts/cell.
If it did, there'd be not only a huge warranty liability, but also a safety one.

You can believe that if you want to but if you actually read that link you will understand. It puts a lot of strain on the cells to go that far down. There is a physical reaction inside your battery of growing and stretching created from the charge/discharge cycle. If you regularly drop the charge to nothing then it makes it harder for it to keep a charge over time. You're more than welcome to do your method of calibration but I'm a firm believer in keeping the battery healthy.

I didn't say regularly. I said every 30-40 days. I have a lot of experience with lithium cells - both manufacturing and selling.
Before getting the One, I regularly used my HiTec lithium charger on my thunderbolt battery to run a discharge cycle, and then balance/charge it slowly.
No one need be afraid of their phone getting below 10%. It isn't causing any damage.
Well i guess its all a matter of opinion. Me and my wifes first smart phones were the htc incredible. I would never let mine die and the battery lasted fir 3 1/2 years. My wife would let hers die once or twice a month, and it lasted for 14 months before it needed a new battery. Got on her about not letting it die after we replaced the battery, much to my surprise she listened, and the replacement lasted for another 2 1/2 years. Both of our batteries actually still work today just not used to much anymore.
I had the dinc2 and followed the same procedure he used and pretty much nuked a battery from doing that same procedure. In less than a year my battery was bad. To each their own but I still don't suggest running it all the way out.

even anker, who is is probably the biggest portable battery manufacturer recommends not letting their products get below 25% because it can reduce the lifespan of the pack. They state that keeping it between 25-75% is ideal.
Interesting article, thanks for sharing OP.
I also leave my phone plugged in while sitting at my desk and let it charge up. Typically I plug into my laptop via usb while at work, once fully charged it shows 'fully charged' and switches the led status light to green.
I try to never let it die either but have to travel for work and do get very low on occasion, once I get down to 10% I typically just shut to phone off to preserve power while I am flying and avoid turning it back on again til I can get it on a charger.
Battery Life
I'm new to this phone,so I'm not entirely sure how the battery life is ... but I heard a while ago that you get the best battery life out of phones when you only plug them in to charge when they are completely dead. I don't do it often enough to see a difference, but has anybody else done it?
You probably get a much more consistent charge while it is dead/powered off. The only problem there is does letting your phone die occasionally ruin your battery or not?

My laptop, which is a Lenovo, has 2 settings. Best battery health and best battery life. Best health keeps the battery charged to between 50-60 percent and then stops the charge. Best life goes up to 100.

Hi, I have some questions for you. Three weeks ago, Motorola let me a Moto 360 for reviewing purposes. I felt in love with it so I ordered one at Amazon and now I have a personal one. But, with both of them, I'm suffering the same problem. After fully charging them, I've never seen a 99% or a 98%. They always drop directly to 97%. I don't know if I'm so unlucky and I've got two bad 360s or if it's a general problem.
I hope that someone can help me. Thanks in advance.

Mine did that too, a lot of the time. Thought it was my imagination, lol
Truthfully it really doesn't matter what it shows, at least when you're in the upper range of the capacity. If you really care to have it as accurate as possible, run your battery down until it dies, then fully recharge it to 100%. It'll probably show 99-100% then.
Battery gauges rarely reflect the charge. Manufacturers have 2 options. You show the true charge. So 0-100% would be a real representation. But, chargers never keep a device topped up at 100% as to not prematurely wear the battery. So once it hits 100%, the smart chargers will stop charging, and wait until the device hits 90% before it tops up again. But if the manufacturers used the true charge method, you'd rarely ever take your phone/watch off the charger and see 100%, it'd usually be between 90-100%. Most people wouldn't like that.
So what they do is something that's somewhat normalized. If the phone is at somewhere between 90-100%, yet it's been on the charger for a while, it'll show as 100% even though it's not. You've only got the picky aholes like yourself where this method gets noticed
The percentage doesn't really matter, its all based on where they set the numbers. Motorola could easily adjust it so it shows 100% even while the battery is at 50%. It must just be 100% just after removing from charger and the smallest voltage drop brings it down. What matters is how long it lasts during the day.
The reason you are seeing it at not %100 as soon as you pull it off the charger is because todays lithium battery charge methods call for the charger to stop at %100 and let the device discharge, usually to between %90 and %95. This offers a longer life span for the battery than trickle charging constantly so the battery is always %100. Laptops do it too and are pretty obvious about it thanks to windows not hiding anything. Both android and iOS hide it just like they fudge signal strength, although you are free to pull battery voltages on most of todays phones.
Hi it happened to my moto 360 too, two or three times now, have u found the "problem" of this? Thanks
Note 7 is my first foray into wireless charging. I figured it would be useful at work for me as I can spend random amounts of time away from my desk throughout the day so when at my desk I can drop it on the charger and then grab it when I need to go. I just wondered if thats bad for the battery?
I already did a full drain and then full charge from there and even that I'm not sure if it's still beneficial to do. But with a non removable battery I want to make sure I'm not doing more harm than good and shortening it's life by having it on and off thw wireless charger often during the day. Thanks.
Its not bad, its actually recommended. Keeping the battery as high as frequently as possible will help in the long run.
Using it while its charging isnt so good though.

From my research into battery life what you write is incorrect. There are other threads on this very subject where I precise my findings.

Apparently keeping the battery between 50-80% is the ideal scenario. It's probably ok to change to 100 but leaving it on the charger once it's fully juiced makes the battery heat up too much which is bad for it.

There has been research that suggests it is better to charge the battery from around 40%-to about 95%, never full.

I looked at some of the research people have mentioned and it does seem that between 40 and 80% is the sweet spot on the Lithium Ion batteries. It says not to charge to 100%, but that the phone is smart enough to stop charging ones full to prevent overheating. But regardless I suppose leaving it plugged in overnight isn't the best idea.
But in my case it sounds like multiple charges throughout the day isn't bad on the battery as long as it keeps it in the 40-80% range? I can manage that, just wanted to make sure multiple small(5-10%) charges throughout the day wasn't also shortening its life span.
Hard to say I guess. I was the drain and fully charge guy. Never any issues. My wife is the opposite, she should constantly top it off or close and her battery would drain faster than mine. Eventually hers would die very early. So who knows.
Always been like this with all our phones
I know some firms in the past have built in charge counters in batteries so you could only charge the X amount of times, but that was a fair few years ago and things have moved on since.
but my phones I have charged them multiple times a day and my Xperia Z1 that I got on launch day is still in use by a friend and still has near perfect battery life despite being charged some time multiple times a day and always being left on charge overnight every night. (so thats for about 3 years now?)
my S6 I have ran on the wireless charger since I got the phone on release day, every time I went in the room I chucked it on the pad to keep it charged up, the phone still works and charges flawlessly, the Samsung charging pad unfortunately wasn't as up to the job as the phone was and died last week. but no big loss as I want a fast charging one after I get my note tomorrow.
-The less you recharge your phone, the better
-Keeping your phone between 40-80% is the best theoretical solution for best health. But if you are running your battery down to 40%, and charging back up to 80% twice a day, that's still more wear than just leaving your phone at your desk plugged in at 100%.
Or say you keep it at your desk and you have to move around office 4 times that day. So every time you leave your desk and come back, you charge it back from 90% to 100%. 4 x 10% - 40% is still less wear then the guy doing the 40-80% x 2 a day. Less charging overall.

Wrong. Going above 80% is a "high stress" situation for lithium batteries. It isn't bad, but the best charging practice for absolute longevity is keeping it between 20%-80%.

Leaving it on the charger doesn't heat up the battery. It just keeps the battery in that high stress state, and isn't good long-term. If you are doing intense activities with it plugged in, then yes that is a combo for high heat which is bad for the battery.

Not really. Leaving it at 100% all day is not the best idea. It'd be better to let it run down to 20% and recharge to 80%. Unless Samsung routes power directly to the motherboard when plugged in, instead of passing it THROUGH the battery first, it is absolutely better to not keep the phone at 100% and charging while using it, heating it up further, and it is still cycling the power/wear through the cells.
Does any of this matter? No. Unless you keep your phone for 2+ years, you aren't going to notice any difference. Charge it whenever and however you want. The battery isn't going to **** out on you because of how you charge it.
Thought the manufacturer warranty was two years anyway? Android phones are only guaranteed updates every two years so may as well upgrade every two years. If the battery craps out inside that time just warranty it. It's extremely unlikely though.

TOO MANY MISCONCEPTIONS. Let me clear them up !!!!
1) Lithium batteries like to sit around 50% for prolonged periods.
2) It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v
3) It will HURT THE BATTERY MORE to keep using it when it is depleted or near depleted. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5%. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%)
4) High Charge and Discharge LOWERS battery longevity. Lithium batteries prefer to be charged slowly and discharged slowly.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
5) Lithium batteries do NOT like heat. Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
I might put this in a new thread.

So basically what you are saying is you the more you use your phone, the more wear you will put on your battery.
100% to 0% drain (100% total) is still more wear on the battery than 80% to 40% 2x per day (80% total)?
GUYS... Come on.

So basically what you are saying is you the more you use your phone, the more wear you will put on your battery.
100% to 0% drain (100% total) is still more wear on the battery than 80% to 40% 2x per day (80% total)?

Basically yes...batteries have a finite amount of charge cycles.
Charging 2000mah into your battery, whether its all at once, or 500mah x 4, should be roughly the same amount of wear on the battery.
For me, only things i ever worry about is deep discharges and heat. Heat is the worst enemy imho.
Everything else is pretty minor when it comes to wear.

TOO MANY MISCONCEPTIONS. Let me clear them up !!!!
1) Lithium batteries like to sit around 50% for prolonged periods.
2) It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v
3) It will HURT THE BATTERY MORE to keep using it when it is depleted or near depleted. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5%. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%)
4) High Charge and Discharge LOWERS battery longevity. Lithium batteries prefer to be charged slowly and discharged slowly.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
5) Lithium batteries do NOT like heat. Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
I might put this in a new thread.

Pretty much covered it here. Good post.
And avoid high heat scenarios as much as you can.

Somewhere in the samsung+ app for note 7, it says always keep the battery between 50 -90 for longevity.

My last phone, an HTC One M8, spent every single night on the charger for the last 2 1/2 years. I would also connect it to a charger in the car when I was driving for any length of time, and that was fairly often as I was traveling regularly. The battery life was not appreciably shorter when I retired it last week than when I first got it.

Hi, I have Samsung Galaxy S20+ G985F/DS (Exynos). Few weeks ago I get a new company car, which has wireless Smartlink+ for android auto and apple car play. I was used to use cable, but few days ago I decided to bought wireless charger (Baseus Cobble 15W) to my car. Since then I have problem with overheating my phone when I am using wireless android auto and wirelessly charging it. I am using Spotify and Waze together and at same time I am charging it with wireless charger, but after few minutes (usually 5-10 minutes) it disconnets with error that my phone is too hot and it will continue charging after it will be colder. When I try to take a phone its damn hot. Is this normal behaviour or my phone is broken?
Running the battery hot will cause premature aging fast; stop doing it.
Software may be using a lot of cpu cycles; wayward apk(s).
Correct this if so.
It's not a good idea to charge and use the phone.
Get a fast charger for the car; you get about 2% per minute with a 25 watt one in fast charging mode between 40-65%.
A 25% charge should last 2 hours.
Li's love frequent partial midrange charge cycles and will get hundreds to thousands more full charge cycles when used like this. Partial fast charging does no harm as long as you keep the temp in the 80-99F range.
Try to avoid charging when under 80F and especially if near or below freezing temperatures.
Been using my 10+ like that for over a year, the battery is in very good condition to spite near all day use.

Well thank you for your answer, but I don't understand you well. Your post is very confusing. But from what I understand, you simply tell me, that I must buy normal wire charger and I must stop using wireless charger because using it is not good? But that is not answer that i want. Because I don't want to plug cable to phone, because when I have wireless android auto in my car, its useless. For example my colleague have car with built in wireless charger. And from what you told me, he can't use this built in charger because its bad?
You have two issues.
App(s) that are using excessive battery.
Charging while using.
Both are best avoided and both drive up the temperature.
Of course you can do what you want but battery longevity may take a hit in doing so.
Karma Firewall is useful for finding unnecessary bandwidth hogs and some of the battery hogs. Start with that.
All wireless chargers make phone hot. Even if you use it at home and no aps are open.

Excellent point.
A damp rag can be used to reduce the temp.
Unless the charge port is broken wireless charging just doesn't seem like a good modility.
Even at high frequency and optimum primary/secondary winding gapping air core transformers are notoriously inefficient.
These batteries are power hungry critters...
Man, I know what you all are saying but imagine covering your phone with a damp rag when changing, imma die of laughter if I see that anywhere. I know it's gonna work but it's going to be funny af
Mine did the same thing, it was 5 days old when I saw it the first time. If you insist using your phone and charging it wirelessly disable the fast wireless charging option from the settings and you are going to be good to go, but don't expect the phone to charge that much, maybe 2% in 5min, something like that probably. It will not overheat, tested it myself. Be careful, if it continues to overheat even with fast wireless charging option disabled stop using the charger when using your phone. I have a suspicion I burned my coil like that, it only took 5 or so times where my phone said that it can't continue charging because too hot. I hope that wasn't the case.
