Battery Info

lithium ion batteries each have a unique id right...is there anywhere to see it in the os? How does the phone decide what the state of charge is? I am looking at an extended battery that says you should leave it on charge 1 to 2 hours after charge light goes green (95%). Where does the light get the info from? Can the charge profile be altered?

Yes, look on the market.
Once I ran accross one, but I find it useless for myself.

I don't think you can view any battery id on your android and i doubt most batteries have such an interface, most are just labeled backs in a plastic enclosure.
If you swapped for an extended battery i would recommend resetings your battery stats (google for how), or else the charge level may be inaccurate.
The information when to stop charging comes from the voltage.
Some unselfish advertisement, my new app can show you the battery voltage.
No the charge profile can usually not be altered except using a stronger charger to increase speed, but batteries love to be charged slowly... increases lifespan.

So there is no electronic id? I was under the impression that lithium ion batteries used a smart charger and id to track battery data...most computer batteries I have seen each had a unique id so it could track individual battery statistics. Will an extended battery not charge to full when being charged in the phone?

Technical Details
Fits in existing space so no replacement door is needed
Made from the highest quality Japanese cells
Capacity: 1750mAh
To obtain the full capacity of your battery, leave the battery/your phone on the charger for an additional 2-3 hours after the charging indicator turns green or the battery status shows full.
Why is that?

Ya most laptop batteries have such an ID, but i have not seen a phone with one.
I'm not sure why it says to do that.
Did you check out my app?
You set it to you show you the battery voltage, charge till the indicator is green, then note the battery voltage, leave it on charger for 2-3 hours, note the battery voltage again.
If it went higher it really charged more, if not, it was unnecessary.

[Q] Strange Battery voltage reading

I am getting strange battery voltage readings while the battery is fully charged . Ideally the peak voltage should not cross 4.2 volts for Li-ion batteries ,IMHO . Also I saw the Moto G review on Anandtech where the battery voltage is given as 3.8 V . But my battery reads a voltage of more than 4.3 volts . So I'm a bit worried about the long term reliability of this battery or my battery in particular . Has any one else checked this on their Moto G . You can see this info by using the secret dial code *#*#4636#*#* ( Lots of other interesting stuff under this menu )
I have a dual SIM variant of this phone .

I don't think it's an issue, mine peaks at 4.325 as it approaches full charge (it's above 4.2 from about 80% up when charging), it will then 'relax' to 4.194 once at 100% (even if still plugged). Other devices I own do similar. 3.8v is the nominal ideal voltage when the battery is least stressed (about 55% capacity) and perfect for long time battery storage.
If you wanted to be utterly anal about preserving your battery for eternity the strategy is never let it discharge below about 30% and never let it charge above around 70%. Lions will last for years and years and tens of thousands of charge cycles in those circumstances with no loss in capacity.

I own another droid device and the removable battery is rated 4.2 V 1500 mah. During charging it peaks to slightly under 4.2 V and reaches about 3.8 V at about 50 % .So it is safely under the 4.2 voltage limit. . Also many articles on battery university talk about 4.2 V being the peak . Hence the query
Is this the same observed by other Moto G owners ?

Mines also 4.3V at or near fully charged.

Maybe Its the moto g's secret of extra long battery life.....dangerously overcharging enabled by default (Also called bump charging)
Bump charging is known to destroy battery life
And since battery is internal...more profits for moto when people come to get them replaced WIN WIN!!

Hey I guess some users have had this phone for a week . Can some onecheck and post the peak battery voltage ? Mine has reduced from 4.33 to about 4.25 .Also looks like the battery life has reduced a bit
Also how does one reset the battery calibration . Is it by keeping the power button pressed and letting reboot twice?

Sorry for 3 months old bump, but I've got a response from Motorola and saw this thread.
X: Hi, my name is X. How may I help you?
(unknown): Hello, my name is [Me]. I want to ask you a question about Moto G.
X: Hello, [Me]. I will be more than happy to assist you on this.
(unknown): I used CPU-Z to look at a few details about Moto G's hardware and noticed that the battery voltage is 4.3V when fully charged. Is this normal?
(unknown): I've read on the internet that Li-Ion batteries shouldn't exceed 4.2v
X: Let me check on my resources. Please hold on.
(unknown): Thank you.
X: No problem. Do you already have our Moto G or you're planning to buy one?
(unknown): I already have one, just checked the voltage with an app (the default android hardware info menu has the same values so it's correct) and I was wondering if it's a bad thing.
(unknown): Is Moto G's battery of higher quality?
X: Okay and yes, it is.
//
I said something about higher quality because I read this: learn.adafruit.com/li-ion-and-lipoly-batteries/voltages
"Nowadays you may also be able to purchase 4.35V cells! These are the latest chemistry, they have a little more power as indicated by the voltage being higher than 4.2V. They tend to be cylinder lithium ion's used for laptop batteries, and lights so its not terribly likely you'll just run into one unless you're looking for it."
So does this mean we shouldn't worry about it?

Power Samsung phone without battery #2

Update 23 November #1: final voltage setting.
Yesterday the battery charged again. I used up it's charge to 18%. After a night it was 17%. Today I tried to use it. I could without power supply till it dropped to about
11%. I guess the battery voltage is dropping. I connected my power supply again. Set it to 4.3 volt. Android shows that my charge is dropping. It drops to 8% and remains there.
Even running 3D game the charge stays at 8%. I measure the battery voltage and it's 0.03V. Battery Temperature normal. Not even warm.
After removing the battery and re-insert. I had to set the power supply voltage to 5.5 volt to make the phone boot at all. The phone draws a current 1.1A (there was a moment it drew 1.8A, did once) ,when I use it heavy. Like running a 3Dmark demo Icestorm. The best settings to make the phone always run: 5.5 volt on the power supply.
If all remains the same and all ok. I will then stop posting messages on this thread.
Update 23 nov 2014 #2
The battery charged to 100%. The battery voltage went to 4.4 volt. 4.2 volt supposed to be the Vmax. Above 4.2 volt is not recommended.
From this moment I cannot recommend anyone trying this home. Will see in the future if the phone can run or a dead battery. Going to drain for a longer period.
Update 22 november 2014 #1: With success I am using a my Samsung Note 3 directly connected to a lab power supply.
Needed materials Final list:
- any smart phone with a Li-ion battery which is chemically dead! Very important! This li-ion battery must show 0 volt.
- A lab power supply like this one Basetech BT-153 (https://www.conrad.nl/nl/basetech-b...c-0-3-a-45-w-aantal-uitgangen-1-x-393647.html)
- 2 small pieces of copper sheet
- any strong tape that cannot conduct electricity
- some technical skills. Ask a electrical engineer if you are not sure what you are doing!
Update 22 nov 2014 #2:
After running the 'broken' battery at 5.3 volt. The battery is chemically active again. I measure 3.9 volt. It charged back to 64%.
I am wondering if the Samsung battery and phone is able to / not able to run if the battery is broken. Perhaps the phone ran because the high voltage made the battery chemically active again. I am not sure. Going for another deep discharge again and let the battery lay on the shelf for a week. And keep it draining energy with a resistor and LED.
Have fun! Well I am =)

Work in Progress (WIP) Highly experimental. Hope to finish my research and provide a safe way for any user to make a dummy battery. And that the phone is powered by
a external powersupply only.
Remember that Li ion batteries can become extremely hot and can explode. Don't short circuit, damage the metal casing any way!
In my previous attempt, I was almost there, but at the last moment I had to give away my loyal S6312. Perhaps later I can finish it.
Previous post for S6312: http://forum.xda-developers.com/gen...r-samsung-phone-battery-t2923590#post56778430
- Don't dissesamble the battery. The reason is that there is an electrical protection circuit inside the li ion cell. Without the cell and protection circuit the outer electronics, that is in
the battery connector housing, it will not work and your Samsung phone will not recognise it as a working battery, and will refuse to boot.
This guide is tested on a Samsung Note 3 N9005, but if my guess is right, then you can use it for pretty much all the Samsung phones! Let's wait and see.
In this attempt, I am confident it will work. My overal plan is:
1) Get a defect battery. Completely drain it to make it chemically inactive.
2) Hook the battery , that cannot charge, onto a lab powersupply
3) Run your phone at your desk without the recharging the battery.

Inside the li ion battery is some kind of protection circuit that must be included with the electronics outside will it work. As someone else mentioned to me.
The outer electronics (right under the 4 pin connector)) + lab power supply equals no good boot.
Electronics attach back to Li ion cell equals normal boot of phone.
Conclusion: use the complete battery as a dummy. Opening a battery is not safe and / or good idea.
Edit:
From a RC car forum I heard that someone connected the power supply right onto the outside plus and minus of the battery. And that it worked.
Since a li ion battery requires a charger to charge , connecting the WORKING battery to a power supply will be bad idea.
That is the reason I am going to use a battery that can no longer be charged. Then I can safely connect it to a power supply.
At this moment I am draining my li ion battery beyond the lower voltage, to make it completely unable to charge.
My method of draining:
1) Enable exposed framework , and enable module "disablecriticalbatteryshutdown". This will prevent the phone from shutting down at 1%.
2) Use the phone till it shuts down by itself.
3) remove li ion battery, then re-insert it back into the phone.
4) try to boot. My battery was wrongly calibrated. After 2 times remove and insert, the battery gained another 10%. That means it saw 11% as critical.....
5) Repeat steps 2 - 4, until the phone does not start at all, the screen remains black.
6) connect a resistor in serial with a LED and keep using the power of the li-ion battery. You need to drain it. Or connect a bicycle lamp of 0.5W or more, that will drain it even faster.
7) Check the li ion battery voltage with a meter. The voltage should become lower then 3.2V. At certain voltage the li ion cell will not become chemicaly active again.
That means it won't charge because the voltage is too low. My cell shows 0 volt after letting it on the shelf in the very very deep dischanrged state.
Now that the battery shows 0 volt, you can safely use it! I don't know when exactly the li-ion is chemically dead. To be safe I waited to 0 volt.

Battery complete dead and tested it (success!!!!)
Today I rechecked the voltage of my broken Li-ion battery. It showed 0V. With Li-ion batteries this means the battery can no longer start the chemical process that enables it to charge.
I attached the plus and minus to the cell plus and minus. Watch out that you do not cause a short circuit. One of the li-ion connections is a small island. At this small island you can cause a short circuit very easy. Just use tape around the island to prevent any problems. I did not connect it to the outside 4 pin connector. There is hardly any place to place a copper plate between it. So I hooked it onto my power supply. Set the voltage to 3.8V. The phone starts, but reboots endlessy. But that changed when the voltage was set higher, the phone could boot further. Only when I set the voltage to 5.3, measured at the cell connectors, the phone boots normally. I have no idea why.
Any lower voltage and the phone refuses to go beyond the first samsung N9005 boot screen and restarts endlessy.
As a precaution I used my infrared temperature gun and checked the temperature of the battery. It stays at about 30~35 degrees. It's stable.
It's running a game for 10 minutes now.
So, I succeeded in powering my Samsung Note 3 directly from a power supply! Awesome. I will make a video of my final setup.
So that you can see.
Video of my Samsung Note 3 on power supply: http://youtu.be/cqClM6Rlblc
Final Update #2: It seems that the li-ion battery is not dead yet. After 1 hour the phone charged to 2%. I checked the battery voltage and it is 3.9V again. So it seems that 1 or 2 days of 0 volt is not enough to kill the battery completely. I thought it was dead, because I measured 0 volt and because I could not charge the dead battery through USB. I urge you to be carefull and monitor if the battery is truly dead. I will start my deep charge cycle again and keep it on the shelf for 1 week. After that I will check again if the battery is destroyed or not.

What worked for me, on a Galaxy S4 mini (the note3 is still "too young" to get immolated on the altar of science) was to remove the battery electronics, solder two leads on the back plate of said electronics where there is continuity with + and - contacts, and by giving 4.2V the phone boots showing 88% charge.
Maximum observed current draw was 1.2A during installation and run of Antutu.

Battery indicator issues after replacing the battery

Hello,
I have bought an replacement OnePlus battery (the red ones) it looked identical to original one, the only difference was that it had an extra sticker hologram like. The battery was replaced at a service center (after I have ordered it my self, it also comes with 1year warranty).
The issue started the first time I changed the battery. It came charged at first to 55%, I used it until like 35% and then I left it to charge. Charging stopped at 90%. Accubattey measures a capacity of 3050 mah. However the voltage was at 4.280V and at this point it will not accept any more current (charging current drops to 0mA).
When normally charging it with the original charger it draws the usual 2 ~ 2.1 amps. Then I drained it to 0. Now it charges to 95~97%.
My questions are. Is the voltage correct for stopping the charging ? Should it not go 4.35V?
Do you think that repeted discharge to 0 cycles my fix this issue?
Should I consider using my warranty, for the battery and request a new one? Also on this topic. On the supplyer site it states that 5 cycles should be performed to calibrate the battery.
Did anyone else experienced this?
Thanks

calibrate your battery and see if you could find any change,if not, which rom/kernel are you on?

Well I am running 25 Dec CM 13 by sultan XDA, I did not flash a new ROM after the battery replacement.
What steps would you suggest for calibrating my battery ?
I was thinking of dischargeing it to 0 then trying to start it until I get no response from the device. I mean not even show the boot screen. Then leaving it like this for two hours. And then retry to start it, just to make sure the battery is all the way discharged. Then plug it in and leave it to charge over night and see what happens. And if it's still not 100 repeat until it happens.
Thanks for the reply.

Samsung S7 - Abnormal battery wear

Hello,
Sometime ago I started to notice battery in my S7 is much weaker than at the beginning. I checked how it works with cleaned system but effect was very similar. Then I installed two apps to check battery wear:
-Samsung Phone INFO: https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
-AccuBattery: https://play.google.com/store/apps/details?id=com.digibites.accubattery
Effect was very similar: according to Phone INFO battery had around 370 charging cycles and it had 76% of new battery capacity. For me this wear wasn't normal. Battery was replaced under warranty.
Now I monitor battery again. Phone INFO noticed 12 charging cycles (AccuBattery shows 28 cycles because it also notices charging between 40-80%) and wear is similar in both apps: 95% left.
I wonder if you would be able to check battery wear in your S7 mobiles and let me know how it looks in this thread? My warranty expires in 2 months and if there is anything wrong with motherboard rather than battery itself I would try to sort it out.
In app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo there is tab Personal and there are two important for me fileds: "Battery Discharge Cycles" and "Battery Health"
Thank you in advance

My 2-years old S7:
Cycles: 513
Health: 84.7

Results from AccuBattery
Mine, after 2years and 2 months:
2.353mAh average.
I assume that would be 78% health. (2353/3000mAh)
EDIT: Where can I see my charge cycles? I will post them when i find them.
