[Q] Battery Health and Charge

Got a problem with my battery I think, the phone switches off even if it's showing 60 or 50 or what ever charge. Once the comes back on it shows zero battery. So plug it in and start charging but if I wait till it's on 2-3% and unplug the charger and leave it the battery indicator goes up instead of down! lol
So I thought it might be a calibration issue so downloaded Battery Calibration app and it's showing "Current Charge: 100%, 4mV" shouldn't the mV figure be in the thousands?????
IS there a app that will show Current charge Level, Designed Level and what the max level is now ???? Like on most laptops?
Thanks

Sounds to me like a major bloated battery. Open your back cover and see if your battery is "pregnant"

Na battery is normal. I have had it for 2yrs now and flash a new ROM every couple of weeks lol
Will fully charge it and check the battery graphs and post back later/tomorrow.
Thx for the replys

The phone switched off (was around the 50% mark) and i couldn't switch back on until i plugged AC in.
Once plugged in it showed zero but after a second shot up to 50%+, and doesn't take long to hit 80% or so.
On further inspection it does look like battery is becoming bloated. Upgrading end of the month so will live with it then sell it to O2 recycling for £30

My SGW is about that old, but I´m having here 4 batteries flying around. The one that was used regulary for about 11 months is already pregnant and not in use anymore, though it´s still working good, so now using another one regulary and the other ones are used as reserve.

Like said 2 years for such a battery is a really long time, so no wounder it get´s bloated and needs to be replaced. Just wounder O2 will pay you 30 pounds for this battery. For this money you can buy 3 new batteries

Best way to charge phone

Hello I was wondering what is the optimal way to charge the s3? With wall charger or in comp? Should I let it plugued more after it says "Charged(100%)"?
I have a Zerolemon 7100mAh

I just picked up a Zero Lemon 2300 and still trying to figure out best way. The instructions they give you just dont make sense to me

They make it looks kinda simple but how can we be sure the battery is really fully charged or decharged etc..

Exactly. Plus every time I read someones post on how they did it its always different.
My first battery charge I did what they said. Charged for 12 hours with phone off. Ran it down to 1% and then recharged. Left it on charger for about half hour-hour past full charge. Did the 5 recharge cycles.
Think second battery I may install and run down to 1% before fully charging. My batteries came in with about 56% charge. I dont see why they would need to be charged for 12 hours like that

fastest should always be wall charger since it has higher current than your usb port in your computer will output, especially if you don't have fast charge enabled (root and rom support required for fast charge).
TL;DR use a wall charger

Yeah wall charger charges up the battery faster than in the computer. But I don't mind the time it takes.. The question is which method is better for the battery? Plus I don't use fast charge since opinion on its risk varie a lot.

Chemically speaking, the speed variation of the reaction shouldn't matter on health. The process is pretty much reversible which is why you can recharge it after draining. The only reason batteries die is because this process isn't perfect, and sometimes chemical pollutants form. In this case the current and time variation shouldn't provide a better battery health either way. For best battery health simply drain the whole way down before charging it. Charging it when its not completely empty tends to make it die faster. (Chem major here)

OK here's the reply I got
Rami Mubasher
For best results we ask that customers let the items die down to 1-4% before your first charge. Leave the battery charging for 12 hours if you are able to. Then repeat this cycling 4-5 times. This will yield the best results the quickest. Hope this helps.

Great answer! And what about letting the phone plugued in at 100%? Like a whole night? I've heard so much things, some says "it's better to always charge it a little when you can because it is bad if it reaches 0%". I know it's a chemical reaction and I know the internal resistor gets altered over time providing less efficient charge/decharge. When the phone closes it is because not enough power comes out of the battery, but the reaction is still there and by pluguing it we revive it.. right? That would make sense to me. That would mean that there isn't a charging habit killing the battery life more than another?

I generally like to unplug when full. The reason being, when it gets to 100% it discharges to 99% and the back to 100% it charges. Now in all reality you won't notice any of this battery dying with current gen li-ion batteries unless you keep a battery for like 2 years of use. But then you can always replace it. Bottom line is its not really worth worrying about. I don't know why people say letting it go to 0% is bad. The less repetitive charging, the better, this means letting it go from 100 to 0 as often as possible.
TL;DR it doesn't matter, your battery will outlive your new phone cycle

Thanks a lot for those clear answers!

How to best charge Note 7

I think the batter is the weak link in this phone. Actually, I think it was that in my Note 4 too. After a good year, my phone started bootlooping and it was the battery's fault. I am not too confident in Samsung's batterys, not because of explosions but because they seem to be not the best. The problem is, if we want to change Note 7's battery, it will have to be done at the service center. So I'd like to keep the battery in good condition for as long as possible.
I have read it is best to avoid fast charging. I also read it is best to keep the charge between 40-80% and not let it charge over night. And to only let it drain to 0 and charge to 100 once a month to recalibrate it.
Do you guys think these are good tips for the Note 7?
I also read that first time I should have let it chargefor 5 hours, which I didn't first mistake there? Thanks everyone.

From what I have researched from chemical engineers who design batteries etc the best thing to do is not allow the battery to discharge below 20% and not charge it over 90%. Fast charging apparently does shorten battery life but all charging methods shorten battery life. All about heat, so they say? In 'normal use', whatever that is, a typical mobile battery could last years?
In thinking about this I have owned since the early 80's maybe over 100 mobile phones and 100 other mobile devices and have never replaced a battery yet? I have friends and family still using some of my hand me downs and they are still going strong.
Appears a very hit and miss science?
Ryland

I am pretty sure I count as a normal user. I also don't think I exposed the Note 4 to too much heat or did terribly stupid things with the battery. Did I just get a bad one, maybe.

It sounds to me that you've been paying too much attention to the battery, stop worrying and you'll enjoy the phone even more.

never let the batt go to 0%, charge max at 90%, thats all you can do, and, dont worry too much, enjoy your note 7

This is off of Samsung site...
Cell phones, originally used for little more than calls and text messages, have evolved into all-in-one entertainment devices. Your smartphone plays videos, music and games, and many include lightning-fast Web browsing and a robust app library. Use these features for more than a few hours, though, and your phone's battery charge may not last longer than a day. You can coax more life out of your phone by charging the battery correctly and tweaking a few power-hungry settings.
Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

I've researched this and tested it for myself not saying this is the answer. I use to go 100 to zero with note 3 trying to see how far I could go screen on time. Biggest mistake I've read from Samsung and makers of lith batteries to not let it go below 60 amd it's ok to top it off as often as possible. Leaving on charger doesn't effect them due to them never fully charging they trickle charge my wife does this every night with note 4 no issues same battery for a year. You get 500 cycles of charge if you deplete 100 to zero it makes the battery unstable when hitting zero lith don't like it. You get 2500 cycles if you do the 75 to 100. I've topped off my note 7 every day lowest going to 60. I play music for 3 hours walking outside only lose 2 percent of battery. Using hotspot I lose 5 percent in a few hours all been the same the way i charge. I had 2 other note 7s I did the opposite. In a week I would lose 20 40 percent battery with hotspot music not as good either. Learn the mechanics other the battery how they work wiki it. Look at the science not opinions or articles. That helped me in the long run. I keep a Poweradd Apollo with me just in case.

Well if Samsung put that info on their page it really about says it all.
Back to stationary phones I guess. I don't want to have to take this phone to the service centre in ten months or so.

Have you read the replies here?
No device can go forever without an eventual battery change. As I said I have owned hundreds of mobile devices spanning FOUR DECADES and have never replaced a battery.
How did you arrive at a 10 month replacement figure?
Ryland

Yes, mostly they don't agree with you . And ten month figure from my experience with Note 4. At 10 months it started being weak, then after a few more months, bootlooping started and it was just because of battery. I love Notes but just don't think they have good batteris to begin with.

If you have a doubt regarding a mobile don't buy it especially an uber one like the Note 7 etc. If you are very concerned about battery and its going to cause you worry go for a brand with removable battery. No one can asses how you use your phone and how long the battery will live.
Sounds like you had a bad experience with your previous mobile and that has caused you some anxiety. All one can do is relate our experiences to you and hope you can make a judgement call based on others opinions?
I have zero reason to suspect the battery life of the Note 7 to be any weaker than my previous mobile devices. Only time will tell. The battery on my crystal ball needs charging.
I wish you well.

I gave my son my note 3 when I got the note 4, the note 3 is now almost 3 years old, and the batt is still reliable, not as when new, but very dependable

I try to plug in my phone when the battery hits 40% and charge it up to 80%. I dont get to strictly follow it but that's the best way to preserve battery life/performance

Battery Percentage Lies?

so I bit the bullet and purchased a new batt at the repeated recommendation of this board. I will find out more if that really was the issue over the next few days of use.
however... 1 issue still remains. it appears that the battery % lies while charging with the phone on... i can't honestly say this was an issue with lollipop as perhaps i just never noticed it... but i normally charge my phone in the AM (not overnight) so that once it's fully charged i can pull it off the charger. what i have noticed is (am on MM now) is that i get the popup that says batt is fully charged (lightning bolt not on the batt indicator) BUT.... if i power the phone down it shows the batt is only at 94-96%... so i leave it be and it takes a good 45-60 mins of further charging to achieve 100%...
what is that??? it seems like a complete software issue to me...
my thoughts are... perhaps it's only specific to samsung and may be related to the note 7 problems and maybe samsung made it to where the software prevents over charging? idk... anyone else notice this?
***note*** i do NOT use fast charging.

Strangely....the battery drained faster than it charged for me. Of course, that's an exaggeration, but Quick Charge on this phone isn't as fast as other phones.
I can say that using it while charging DEFINITELY affected the charging speed more than my last phone. It does not charge quickly while charging AT ALL.

Using your phone while it's charging does not destroy your battery. It may not charge as fast because you're obviously draining it at the same time, but it's perfectly fine to use the phone.

Your battery simply starts to degrade once you start draining and recharging. There's a difference between degrade and destroy. If it really destroyed our batteries, phone companies and cell phone carriers would be telling everyone to absolutely 100% do not use your phone while charging. That's just silly. How many times do you walk through an airport and see people sitting on the ground by an outlet, so they can charge and use their phone? Same with laptops. The batteries in cell phones now are so much better than they were before.

That's an old "wise tale". I do it on every phone whether it is needed or not though. I actually do it twice. I take it to around 10% and back up to 100. I still fully charge it before I even use it. May be a waste, but for some reason, it gives me a certain "pleasure".

They don't produce as much heat as SD820 or SD845 so shey can still keep battery cool and let it get charging., or they put their phones aside and let them get battery charged fast because its not charging as fast when being used. Like G7.
Using G7, especially gaming or watching Youtube on mobile cell produce too much heat and battery gets warm fast. So to prevent Note 7 style overheating and explosions both Samsung and LG makes speed of charging lowest in that case. Even that was stated by Samsung's advertisements when Galaxy S8 was introduced. You may search for them on Youtube. LG does the same, it become charging with 0.5A like form USB 2.0 port, lowest possible speed. It prevents battery from heating to avoid degrading and explosion. Turn screen off, put phone aside for half an hour and let it suck up juice
