[Galaxy S I9000 Q&A, Help & Troubleshooting] botolo78:
Hi guys, sorry for the noob question, but I'm a little confused.

My SGS in running a stock JPO. Suppose I want to install a custom rom based on JP(x) (ie Doc Rom : X-mas special: JPY).

Do I need to flash the JPY with Odin and then install the custom rom or the custom rom includes the JPY data?
[Galaxy S I9000 Q&A, Help & Troubleshooting] tackygr:
Either flash JPX,or find a custom rom that supports JPO.
[Galaxy S I9000 Q&A, Help & Troubleshooting] botolo78:
So in the specific case of the "Doc Rom : X-mas special: JPY" I shoud flash the JPY and then the rom.
[Galaxy S I9000 Q&A, Help & Troubleshooting] tackygr:
I guess so unless Doc sais it supports JPO,have a read in his post to make sure.

[EVO 4G Q&A, Help & Troubleshooting] ICEReaction:
You tried to update your phone via Sprint's OTA update? I assume you removed some apps from the phone after you rooted, and because of that, that's why you are getting that triangle and yellow "!" icon. Best bet is just to download a rooted stock ROM based on build 3.70 and flash that. The only rooted stock 3.70 ROM that updates everything (include radio/wimax/pri/nv) is chris's Sprint Lovers All-In-One, or you can flash a custom ROM and then grab the combo radio/wimax/pri/nv zip and flash that.

[Q] Wifi Tether: Subject to $15 T-Mobile Charge?

Curious about this. Currently I'm connected to my laptop for the past 15 min just fine; no alert came up that said I had to get the $15 fee that T-Mobile charges for the "privilege" of tethering on my current plan. Does that mean that an unlocked phone isn't subject to T-Mobile's tampering?

If so, is this the only value for rooting right now? I don't see any other need for root with this phone except if it fools T-Mobile.

I know there are numerous threads about battery life, but this one isn't about the life itself really.

I can charge my phone to 100%, but when I unplug it, the battery indicator shows 97% right away. I plug it back in, rinse and repeat, and get the same issue. I even tried charging with the phone off.

Ha anyone had luck with using a full 100%?

[Nexus S General] slowz3r:
Id keep it, there was an article posted in one of the threads stating why phones do this...the N1 did a similar thing where after it charged going from 100-96 percent went really quickly

[Nexus S General] cosimoss:
Full charge oddity

When the phone has been switched off and charging the phone shows the fully charged icon on screen when charging appears to be done. Battery Indicator Pro displays only a 95% charge when the phone is switched on. The same happens when the phone is on and being usb charged. When 100% charge is shown and the usb cable is removed the charge is then shown as 95%. This does not happen on my other devices running 2.2. They will show 100% or 99%. A device design or 2.3 bug?

Weird battery reading

My Nexus S was at about 16% when I put it on the charger then I did a quick reboot and it said it was at 52%. I unplugged it, powered off, pulled the battery, then rebooted and it read 28%. Even that is hard to believe after less then 5 minutes of charging. Has this happened to anyone else?

Stock 2.3.1 unrooted
[Nexus S General] Luxferro:
Yes, that has been reported by a number of people. It has happened to me as well when rebooting while charging. Nothing is wrong with your battery though, it just must be a battery stats bug.

[Nexus S General] Luxferro:
that's normal too. but totally different thing then the OP posted about.
[Nexus S General] Crackaf3tt:

No, a jump of that much could only be a glitch.

To prevent over charging it generally only charges to around 96%

post a screenshot of your battery chart?
[Nexus S General] distortedloop:
Sounds like some app ran amok.

Have you gone to Settings/About/Battery Usage and looked at what items are being reported as sucking up the juice?

While in there, if you tap each item, details will come up, like how long the app was in use, the cell in standby, if that app kept a wake-lock on the phone (wake-locks can be big battery sucks).

Also, on the main screen there, if you tap the timer at the top of the screen, you'll get a nice graph that might give a clue as to when the heavy discharge began, and what your signal strength was, wifi, cellular, etc.

Your experience is well off the norm. This phone has AMAZING battery life; it's unreal to me compared to my other 4 Androids, and even to my iPhone collection.

[Nexus S General] allen099:
You'll need to download the Android SDK and use the DDMS app to recognize your device, and take a screenshot using the menus above. Sorry I don't have it open at the moment to be exactly precise.
[Nexus S General] distortedloop:
You have to be rooted and install an app for it to take a screen shot, or use adb from you computer (complicated).

You could take a picture with another camera and post it.

On the actual graph, does it have a steep drop off point, or just a long steady decline.

23 hours and 15% isn't horrible on a non-Crackberry smartphone, but many of us get better than that.

What seemed unusual was you said it went from 70-15% in just two hours.

I'm more interested in the listing of apps and what percent they used from the screen before the graph.
[Nexus S General] golu12:
yep its long steady decline but at the end(when the phone was least used) its does have a red outlined kinda-sudden decline

about that 2 hrs thing, the phone was at 70% at about 10pm and now at 12am its 15%..

during this time everything including bluetooth gps wifi auto sync 3g everything was of and, the phone wasn't even 'unlocked' 'once'.!!!

my phone is already rooted, ill try to take the screenshot..
[Nexus S General] golu12:
it went from 70-15% in 2hrs for me lol
[Nexus S General] distortedloop:
I like DroCap2 for screenshots and use notification trigger setting.

on the SGS phones the battery power detection is accurate

it only became inaccurate after you flashed to many ROMs on the SGS

A strange thing: my Nexus S, with the charger connected, normally reaches a maximum charge level of 95% (fully charged battery indication). Then, disconnect and reconnect the battery charger, to 98% (again indicating the battery fully charged).

[Q] Battery charge bug?

Hi,

I'm wondering if anyone else noticed this -- as soon as I unplug my Nexus S after it has fully charged, the battery indicator [using Battery Indicator Pro] goes from 100% to 96% (sometimes 97% or 98%), and when I plug it in, the lock screen says "Charging - 96%". It takes only a few minutes to charge fully, but as soon as I unplug the charger it immediately loses 2-4% of the battery.

Is that a Gingerbread bug or is that a Nexus S hardware/battery issue? Am I the only one experiencing this?
[Nexus S General] unremarked:
SEARCH.

It is your friend.

Answered in sticky FAQ in the Nexus S Q&A section
[Nexus S General] mishkasf:
Thanks, unremarked!!!
[Nexus S General] slowz3r:
can i just point this out.

The link in my signature is a very good reason this happens
[Nexus S General] RogerPodacter:
i know the FAQ attempts to explain this behavior, but i dont buy that explanation really. other phones like my nexus one do not drop 3% immediately upon unplugging the charger.

after looking at the nexus S battery driver vs the nexus one battery driver, the two battery chips are different. the n1 uses a variation of "coloumb counting" which counts the current passed thru the sense resistor in the battery. the nexus s seems to be based off of voltage tables to indicate state of charge. as such, voltage tables commonly do this because the voltage drops as soon as you unplug the charger, dipping the voltage and throwing off the percentage reading.

this table below is pulled from the nexus S source code, and nexus one does not use this method and has no table:

/*
* Battery Table
*/
#define BATT_CAL 2447 /* 3.60V */

#define BATT_MAXIMUM 406 /* 4.176V */
#define BATT_FULL 353 /* 4.10V */
#define BATT_SAFE_RECHARGE 353 /* 4.10V */
#define BATT_ALMOST_FULL 188 /* 3.8641V */
#define BATT_HIGH 112 /* 3.7554V */
#define BATT_MED 66 /* 3.6907V */
#define BATT_LOW 43 /* 3.6566V */
#define BATT_CRITICAL 8 /* 3.6037V */
#define BATT_MINIMUM (-28) /* 3.554V */
#define BATT_OFF (-128) /* 3.4029V */

at full charge my phone levels off at 4.17 volts for a few hours. soon as i unplug it it drops to 4.11 volts, then fluctuates and decreases from there. if my phone followed the voltage table above, it's easy to see why a few percentage points would drop immediately.
[Nexus S General] BrianDigital:
Would this charging scheme affect extended batteries from fully charging much like on my evo
[Nexus S General] sedde:
Weird battery.

My battery is giving me weird readings.

So i bought a SNS like 3 days ago, what my problem is, is that i charge it fully, and when i unplug the charger it immidiately drops down to 94% and goes from that point and on.

[Nexus S General] zephiK:
Okay since you cant find it in that thread theres a link linking to another thread

http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/

tl;dr manufacturers do this on purpose and not have your phone charged to 100% because if it gets to 100% and is being charged for a long time... it causes harm and may cause your phone's battery to lit up in smoke, fire, damaged battery, dying battery and the list goes on because the battery is being overheated due to long charging (when you go to sleep, you keep your phone charged... leaving it overcharged for longer periods of time) [note: parts of this may be inaccurate because im just freestyling it.. but the facts are on that article]

the smoke coming out of the battery is a causality caused by a kernel which removed the 100%, so therefore if u unplug.. it'll be 100% and will stay fully charged when unplugged. the result was the OP of that thread you read regarding about smoke
[Nexus S General] RogerPodacter:
Just want to go on record that I don't believe they do this on purpose. My nexus one goes to 100% just fine for the last year. As well as all my other phones. Nexus s is the first I've seen this.

It's a bug in The battery driver, I'd bet 1000 bucks on it. Just look at the source code and see.
[Nexus S General] zephiK:
It isn't just the Nexus S.

There are other phones that have this feature in stock.

Samsung Galaxy S (I900, Epic 4G, Captivate, Vibrant), HTC EVO 4G (I believe)

.. and others
[Nexus S General] kenvan19:
I'll take your bet. Hundreds of devs have edited said source code to allow for what is called "trickle charging" and there is actually quite a debate about it over on the Evo forums. I have seen it on an HTC T-Mobile MyTouch 3G, a Samsung Galaxy S Epic 4G, an HTC Evo 4G, and now on my Samsung Nexus S.

The issue comes from the fact that the battery controller turns off charging at actual 100% and registers the battery as full (hence why your phone will tell you that you are fully charged), then the phone continues to function meaning it is running down battery life until it reaches a threshold level and the phone charges to actual 100% again. While I do not know what that low level is on the Nexus S it is 90% on the Evo.

As another poster stated this is because allowing the battery to continue charging past actual 100% will cause an excessive heating of the battery to the point that it can sometimes catch fire and explode. Again, this is a well known fact. The threshold of lost charge before recharging occurs differs on different devices (for example my Epic 4G never was below 95% when I took it off the charger) as there is no standard, just what the manufacturer thinks is the correct balance of safety and battery usability.

So, shall I expect a check or should I link paypal ;)
