[Q] Generic Android Battery Problem - General Questions and Answers

My SGH-S730m (no device forum for this phone yet) battery percentage was at around 80% when I turned it off. It was placed in a pocket with another device. I can 100% confirm it was off for a complete 4 hours.
When I turned it on, the battery level was at 5%.
The battery still charges, the phone still works. The battery has not exploded yet, and is currently at 45% charge. I am using samsungs OEM battery (it came in the box with the phone). I have had this phone for just more than 2 months now.
What the heck happened? Is my fuel guage messed up?

Have you ever tried battery calibration?
1. Charge phone to 100%
2. Discharge to 0%
3. Let phone sit for 5 minutes
4. Plug it in without turning the phone on
5. Charge without break to 100%
6. Repeat 2-3 times

I also is same...

That might be a fix, but im looking for the reason behind this problem.

Does anybody know what went wrong? My phone still works (if that even means anything).

Sometimes it happens that the chip goes mad. It happens with every android phone. You're lucky that you have removal battery. Some devices is difficult to do the above trick. I think when you do a full charge and disconnect the battery from the phone for 5 minutes it will be good again. I'm not kind of advice let battery go to 0 because you can ruin li ion battery with a full discharge.

How long did you have this phone?
Can't you get it exchange for a new one in case the phone has a problem?

I don't know where you from but in Europe you have 6 months for battery and 2 years for phone.

What I meant was, if it's still within it's warranty period you should get it exchanged.
If not, swap your battery with someone and see if it's your phone or the battery.

Indeed.

I won this phone for $7 at a stack-em machine. I doubt it has warrenty.

Sorry pal I can not answer that. But try the exchange battery suggestion from the other user. And try mine for calibration.

Is this a one time only issue or did you get that a lot?
One time only can be from a stuck process in your phone
If you get that a lot => try the warranty

One time issue. I noticed that the phone was getting really hot (even though it was off).

Nope, you can't. It reads 0% while actually it's voltage is way above 0mV (actually somewhere above 3V) and that's a preventive so that you can never discharge it even close to full discharge because going over 0.5V below the nominal voltage would ruin most Li-Ion batteries so it simply doesn't even allow you to do that. And besides, from where do you think it draws the juice to blink the LED when you try to turn the phone on after a "full discharge"?

You should buy a replacement battery then ASAP, they're pretty cheap these days. You don't want Li-Ion packs overheating and the liquid inside them catching on fire.

Li-ion battery are intended to work between 40 and 100 working below that is in most cases the ruin of a battery. And experts say even 98 % slhould be optimal full charge not evem full.

Can you please quote some sources and prove that this is not just a speculation by yourself? I understand the physics of electricity and the foundations of marketing and economy well enough to say that what you wrote is utter nonsense.

Just read the thread from gokhanmoral from here. On galaxy s3 original development thread.
Sent from my GT-I9300 using xda premium

I already know what the problem is. What I want to know is "what" happened to the battery.
Why, would the battery die so quickly when the phone was off? Why, was my li-ion battery discarging the energy as heat? (which would expain the heat while it was off). Why, does my phone still work?
Years ago, I fried a pocket pc by using a 10A charger instead of the usb 0.5A standard (is it 0.5mA? - I cant remember anymore). The battery didnt actually explode, but it got HOT! Really hot. I came back 10 minutes later to discover that my battery was discharging while plugged in..
I fried my fuel guage hardware. Tried to save it, but there was no way. Even after unplugging the 1 pound beast from the charger, the phone was discharging around %4 every 30 seconds. I learned my lesson from that horrific event (I loved that phone so much).
Now, who "actually" knows what happened to my battery? Anyone? I dont need a fix - so dont bother posting if your going to tell me to buy, sell, or repair, and not tell me why.

Overcharging the battery?

Is it possible to overcharge the battery? I ask because when I first got the phone and fully charged it, it would stay on 100% for at least a couple hours (using circle battery widget which reads in increments of 1%) but one night I fell asleep with it plugged into the charger and when I got up it still read 100% but as soon as I unplugged it it went immediately to 99%. I have not yet been able to get it to read 100% unless its connected to the charger. Think I could get the batt replaced under warranty since its only 2-3 weeks old?

Your battery is fine, it is set up so that it will not overcharge. I tried searching for an article that explained how the system is set up but couldnt find it.

I'll look in to that. But what about the battery immediately dropping to 99% when I take it off the charger?
sent from my Motorola Atrix 2 via Tapatalk
Every android phone I've had has dropped like that as soon as I've taken it off charge, nothing to really worry about.
They do a think called power cycling. It will charge it to 100% then shut off then once it goes back down it will charge it to 100% again. Ill try to find the article. Your battery is fine.

Weird. My SE Xperia X10 didn't do that, it would stay at 100% for at least an hour. I recalibrated my battery a couple days ago, thinking it would remedy this "problem" and after it died on me I charged it back to 100% and took it off the charger at 10pm, set my alarm on it and let it sit overnight. After pressing snooze on my phone 3 times and finally getting up at 630am it still was at 100%! So it's strange to me that this drops to 99% immediately but if it's happening to everyone else I won't worry too much.

Well if I were to judge off that, mine stays at 100% for hours......im going on 7hrs right now. But I use battery circle widget which reads in 1% increments......as soon as my phone comes off the charger it goes straight to 99%......it didnt do that before.

Battery Charging & calibration query
What difference does it make if you charge from empty to 100% in switched off stage and the same in on state? Which is better? How should we calibrate the battery and how often using which app for unrooted MB865 Asia retail? Also if phone dies (switches off) constantly due to insufficient charge does it harm the battery in terms of cells getting destroyed gradually & finally does switching off or switching on the phone while charging have any effect issue on phone or the battery?? Thanks in advance for inputs for all queries.

So whats the best method for a first-time battery charge?

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?
I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.
Thats exactly what I did, I let mine completely die and then charged to 100%.
Be careful with how you charge the phone, rather with how low you let it get.
Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.
I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.
Full battery cycles are not good for long term life of Li ion batteries.
Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.
The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.
Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.
I do the same thing for all of my phones.
1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%
Then use it normally

How do you tell if the phone is charged to 100% while off?
While on, my battery percentage doesn't seem to go past 99%. Is that correct or is this last 1% just taking a very long time?
Update: NVM last 1% just took forever. LED does turn green when fully charged.

The LED will turn green once it's 100%.
Don't worry about letting the phone die and charging it up to 100%.

Mine came dead too. Charged it to 100% and now been using it and so far have 36% on 3h 9m on battery.
Screen at 84%
Does the battery life get better? Because it seems to be draining rather quick. Even though I have screen brightness less than half.

@Maroon Mushroom, Correct these lithium batteries dont have memory effect, but over discharging them will shorten its life.
I dont want to sound like an expert, but discharging the battery until it dies is not recommended. It will affect battery life/performance.
A couple of good references here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
http://batteryuniversity.com/learn/article/discharge_methods
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table
Ya, we use Lithium Ion (Li-Ion) batteries now which dont have a memory. The older Lithium Polymer (Li-Pol) batteries did have a memory and needed a certain charge method to get the longes life cycle out of it.
Awesome, thanks everyone
I turned it off at 20% and wen't to go buy my MicroSIM (ugh...) cant wait to play with it tomorrow
Why would you buy it? Pretty sure they would give one to you for free

Hmm, i hate the idea of letting it die completely. But what i've always done is turned everything on and ran it through a low-powered usb source so it has a charge but the battery is still draining. So even if the battery runs dead it has power via USB plug [make sense?]. Usually having everything on [i do mean everything] and downloading a torrent so the internet is constantly under use. Then again i'm not sure how the One X will work out for this, but thats what i'm planning .
guys its lithium...u cant drain it to 0...even when android shuts down your at around 3.6volts. thats definetly not 0volts. no memory and android wont let you ruin your battery...so charge however whenever.
im qualified in lead acid. ni cad. nimh and lithium batteries. trust me..u cant hurt it unless you short it! !

How to make your battery last longest?

So I just got my galaxy s3. I haven't turned it on yet. But I heard that you were supposed to charge it fully and then let it die. Then charge it fully again and then start using it. That when. Doing this you will optimize your battery so it will charge faster, hold a charge faster, and just last longer.
Is this myth or fact? And if fact how do I do the steps so I get it right?
Thanks for the help and sorry for any mistakes it was typed on my phone that has aa small touchscreen.

Now is this ALWAYS the case?
To clarify what I am asking I am saying does it always harm the life of the lithium ion cell by letting die fully? Like even after 6 or 8 or 12 months of owing the phone (or any device), not just one the first charge. This could be very useful for further reference...:good:
There are some things can help increase life of litium batteries. First, don't let it go down to 0% as mentioned, keep not lower than 50%. Once per month it is recommended to discharge battery to 0% and then charge it to 100% again for device callibration.
This is a good question. I always thought that by discharging and charging batteries at full cycles, you would make their total useful life last longer.
In fact, this happened to me with a notebook, which I used to play with and charging at the same time. In the end, the battery lasted for a few minutes and I had to sell it.
But in all: is this really true? I would also like to know if is truth or myth.

This happened too (as funny as it is) my grandma. She would ALWAYS have her little nnotebook plugged in and eventually it drained. I found out because one day I took it off the plug a d it died while I was on facebook after around 7 minutes.
So I bought a new battery and now she charfes iit and takes it off the plug to use it and twice a month she lets it die and it has worked

It is true if you have a phone like Nokia 3310 if you do not have a NiMH battery do not do that you will lose time also you do not need to "format" a Li-Ion battery
read about lazy-battery effect on Wikipedia
rooting you phone to underclock/undervolt should also help out battery life pretty significantly ^_^
Lithium ion cells do not suffer from the "memory" effect as older rechargeable batteries. You do not have to let the battery run all the way down then fully charge it again to get the best performance that way, that was for the older types of batteries (again so you wouldn't get that "memory" effect) matter of fact its rather harmful to the battery to run it all the way down.
Charge the battery as often as you want no matter at what level it is. If you are going to do some high power **** (play a game, watch a movie) then plug it if if you have a charger around. The longer the battery stays at a high level the better for it. Try not to let your battery run your phone at a low state (charge it asap). Its ok to leave it on the charger even after its fully charged. Your phone and charger are smart enough to know when to start/stop charging the battery. This will ensure a long life for your battery.
...as for your phone...simple rules...if you are not using it( DATA, WIFI, GPS, SYNC, BLUETOOTH) then turn it off. Screen is the biggest battery drainer...KEEP IT ON AUTO!...darker themes really help alot...make your screen go off at 30 sec. or less. Have fun with your new phone homie.

Battery 100 to 0 in 1 sec

Hi, I'm using the AT&T One X with Team Venom ViperXL 2.0 rom.
This morning (while it was still connected to the charger) I received a call, got stuck (I couldn't use it at all until the call was dropped) then I noticed the home-widget clock was showing the correct time, while the statusbar clock was 35 minutes behind
I've rebooted the device, and noticed that although it was connected to the charger all night I had 0% battery.
all this time the device was scorching hot (like when playing a game and charging at same time).
I've poster a screenshot of the battery usage.
What could have caused this and how do I stop this from happening again?
Thanks for any help
I would let the phone drain completely then do a full over night charge while the phone is is off, do this cycle a couple of times.
Did you notice you have some bad wake locks?
You should use better battery stats and find out what's stopping your phone from deep sleeping like it should.

Thanks everyone. I've done one discharge-charge cycle, will repeat the next couple of nights.
I'll update if the problem comes back
Its just a metering error, not real life battery drain. I'm not an electrical engineer or anything. But I don't see how its possible for that much power to be discharged without a huge amount of heat or light, or the device being grounded.
The only thing I've seen clear this up, is a factory reset.
Charge cycles to calibrate the meter can't hurt. But I'd caution against discharging to "zero" (phone shutoff). Discharging to 10-20% is plenty accurate enough. Over-discharge of Li ion batteries can render the battery unable to take a charge. While the voltage doesn't truly drop to zero, it can drop enough to shutoff the safety circuit. I've seen it happen to this and other Android phones in the past (person drained to shutoff, then the battery won't charge).

You might be right about the flash and bang, but the phone seemed to charge like it was really on 0%. maybe the read of 100% was wrong and the reboot fixed it; but why would it be on 0% if it was plugged in to the AC all night? That's also an indicator of a problem, right?

A similar problem was discussed thoroughly in another thread. One person mentioned that its possible there is a short between the battery layers. But I would think such a thing would make this event happen more frequently in the case of a hardware failure such as that.

How do you handle your battery on a new phone?

Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?
I also remember someone telling me that you shouldn't let your battery run completely empty, is that true?

just charge it when it needs it, dont worry about what % its at, and dont worry about running them right down... the phone will power down before it gets to a dangerous level for the battery.
dont leave it plugged in all the time when its sat at 100, dont leave it down at 0 and just forget about it for weeks on end...
thats all you need to know

in fact... read here, and note the bit about wireless charging! http://gizmodo.com/how-to-take-care-of-your-smartphone-battery-the-right-w-513217256
Just enjoy your phone. Don't make it so difficult.

THIS IS XDA...
I suggest you lower your brightness to 0%, turn off the useless 3 cores, underclock to 100mhz, undervolt to 0.1v, turn off wifi/data/bt and be on airplane mode all the time and enjoy your month long battery life.

I don't buy the bit about wireless charging. I've used my Nexus 4 with an LG wireless charger daily for almost a year now and haven't noticed any side effects with battery drain or overheating. In fact, I'd argue that the Nexus 4 and my Nexus 7 get hotter when plugged in than they do on the wireless charger. I have absolutely no reservations about using the Nexus 5 on my LG wireless charger when it arrives this week.

Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?

Well the charge and discharge isn't necessary, IIRC that's only for older battery technologies like Ni-Cd batteries (Nickel-Cadmium). On the other side, you probably shouldn't let it discharge all the way since these are Li-Po and it could shorten their lifespan (apparently).
I just plug mine in whenever I'm near a charger.
I'm at work at my desk... its plugged into the charger.
I'm in my car... its plugged into the charger.
I'm at my girls house... its plugged into the charger.
I'm at home replying to xda / android central posts... its plugged into the charger.
This is what I've done with every phone I've had. I only had issues with one battery. I used to have sprint and I had the Samsung Galaxy S2 Epic 4g Touch. After about 8 months the battery got fat (they said it was called a swollen battery at the sprint store) and it kept turning off. They gave me a new battery at the sprint store and I continued with my routine above and never had any other issues with it or any other phones.

this is right on both accounts. you dont need to discharge it all the way, and doing so will reduce its life a little. i recently read about lithium poly batteries and the particular blog i was reading talked about running the battery down to 20% then charging it to 80%
i think when i first get the device i will use it down to 0%, charge it up to 100% uninterrupted and then hopefully keep it within that 20/80 range and probably doing a 0-100 refresh on the first of every month
If you guys want to read some in depth material on charging lithium batteries I would recommend reading this. Very informative.

That's actually the concerning part when I do overnight charging, it's sat at 100 for quite a while!

It's fine. Phone manufacturers know that people charge their phones overnight. That's why there is a trickle charge mechanism built into all phones nowadays.
u have to calibrate the battery too
Over the last month I've had somewhat of a binge of buying phones from Amazon and returning them for one reason or another and I've noticed that the first 1-3 days of phone ownership are usually the toughest on the phone / battery.
I've owned over the last 2 months (in order):
- S4
- HTC One (x3 as 2 were faulty out the box)
- LG G2
- S4
- N5
I've decided on the N5 as being the best for a number of reasons, but my favourite is price.
I havn't worked out whether it's a combination of new phone = more usage or new phone = requires battery calibration. But the N5 is the only device out the major players that actually made it through day 2 (the day after it came out the box) without a charge midway, infact it's ONLY JUST gone on the charger after some 28 hours of moderate (3 1/2 hours screen on) usage.
My gut feeling is that once you're out the first week just use the damn thing, but the first few charges can make a difference to how quickly the battery feels calibrated. My N5 came with 50% charge out the box, I ran it down to 0% and topped up charge as much as I could the first day. Once I got home I once more let it 0% and then did a full 0-100% recharge. Then my 28 hour experiment started and now I'll just use it as normal, and not worry.
I keep brightness at 50% to enjoy this beauty and I do not give a single **** about the battery.
Charge battery between 20% - 80%
Do not use phone while charging
Unplug charger when battery full
