Self Charging - Nexus S Q&A, Help & Troubleshooting

Battery was 28% last night, the phone gained 3% overnight when It usually drains 2%, no usb connection as you can see in the graphic. What could cause this behavior? I’m just curious.

Perhaps its an issue with your battery controller. It was projecting a certain loss of battery but when it did not after waking from sleep it assumed it had charged and displayed a higher %?
That is completely conjecture based in no fact other than those made up by me, so please take it with a grain of salt. =)

i'll keep saying this, but nobody wants to look at the nexus s battery driver code. seems the phone is based off voltage tables, which fluctuate under load, and hence when you charge to 100% and unplug, it drops to 97%. because the voltage drop.
same could apply to this situation, very often you can see your voltage drop like that. especially if you left the phone idle all night after using it hard prior. voltage drops then increases.

Yes, I was using maps very hardly (at least in comparison to the rest of the day) and that’s the reason of the fast drop in the graphic, then the phone went sleep for almost 7 hours. I’ll take a look at what you’re saying about voltage tables. Very interesting info here.

you were using maps right around the time of that drop? then yes that's the reason. i wasnt directing the "code review" to you lol, just more of a general thing that was discussed in the forum previously. sorry
but this would definitely show, in my opinion, why there is also the 100% to 97% drop when taking the phone off the charger. voltage drop always ocurrs here.

No reason to be sorry about, I didn’t take it that way; I just like to learn new stuff about how things work.

its the battery meter. you probably rebooted. the battery meter in android is known to be inaccurate. sometimes after a reboot it can gain or lose percentage. ive gained 25% before after rebooting! in reality, you didnt gain anything, its just the meter being off by a bit.

I just want to know how you get nearly 4 days of use out of a charge!
Don't you use your phone?

I haven’t seen this after reboot, this happened after awake and it wasn’t sudden. Phone without signal in the graphic is the “airplane-mode” It wasn’t off. I know that battery didn’t gain any charge, of course, It’s just the weird behavior of android reading battery information.

lol, yeah, It was a very quiet week.

it would be awesome if you could test this if you dont mind. turn your screen brightness to max, make sure your on 3g and not wifi, open google maps and scroll in one direction for about a minute or 2, check the battery percent and voltage. then turn off the screen, leave it sit for a few minutes, then see the percent and voltage readings.
maybe try a test a few times just for fun...you wanna place as much load on the phone as possible, so maybe even turn on the camera flash?

does any body else has an easier way, or can recommend a market app to test the battery life by using full features?

Quick test here:
Beginning with 3728 mV, stress the phone a little and It drops to 3622 mV, then I let the phone sleep for couple of minutes and after wake it battery shows 3730 mV. It seems to show higher values than those that were present before sending the phone to sleep. What could be said about that?
I’ll do another test with full charge and more stress, but for the moment, my phone is charging, yeah…. Finally.

its too bad my app (my sig) doesnt work for the nexus s, because i just recently added real time voltage vs current graphing, taking 2 second readings, for these exact circunstances. its fun doing these types of tests on my n1. but the battery driver and model is too different in the nexus s to use the app...
n1 doesnt use voltage at all for percent readings, but my hunch from code was the nexus s does. that's why i was so curious. check out some screens though for fun. you can really do some interesting tests with such high sample rates.

Huge battery life fix.

I am using the stock radio. This has been confirmed by others as working also.
Seems as if there is some sort of bug with with Cell standby that causes the phone to lose signal which in turns just kills the battery. To verify that your set has the problem, check the Cell standby info in the Battery Use info. If the Time without a signal is higher than 0% (50% seems to be the norm) than you have a problem.
One solution, at the moment, is to follow these steps:
1. Plug in phone charger or into USB.
2. Put phone in Airplane mode
3. Put phone to sleep for a minute
4. Turn off airplane mode
5. Unplug phone
My Time without a signal is at 0% for over 16 hours now. The battery life is much better and the phone didn't die on me last night while i was sleeping.
I am using the new Radio and mine was @ 58%. I will report back with any change that this makes.
Also testing. Mine was at 32%.
Didn't work for me
I am running the stock radio and after following the instructions cell standby was at 0%. 5 minutes later, I am back up to 46% so I guess it didn't work
Tried it twice with the same result.
Ok, followed your steps. Using the new radio, after 2 min with the phone in standby, I checked again. Shows it sitting at 40%. So I dont know.....
same here...it's back up to 48%
I tried this and after 10 minutes of standby mine has dropped from 56%% down to 30%. What exactly does this fix do and does it have to be done after every reboot?
Well i tried it and thus far it's had no effect my cell standby is back up to 40% was at 50% it's been climbing steadily.
Perhaps someone can correct me but it was my impression that "Cell Standby" was NOT time without a signal but rather cell time spent doing nothing but communicating with the towers. Since the phone is always communicating with the towers then it's going to show a high percentage of battery usage.
I imagine the reason you are seeing less % with Cell Standby is not because your saving battery but rather other applications (I don't think they all show) are using more battery time.
Anyway I don't know this for fact, but it makes a sense to me. Perhaps someone else can comment on this.
You need to press on Cell Standby to see Time without a signal , this is what kills the battery.

Were not talking about cell standby, were talking about time without signal, which is a huge battery drain, and is under the cell standby category.

Thanks for the correction, however I did go under Cell Standby and I do not see the settings you are referring to. Perhaps there is a ROM difference (damagecontrol 1.0) or maybe I don't have any time without signal.

I did it one more time and it worked this time.
I'll keep my eyes on it until tomorrow and see if there is a difference.
OP, do you have to do this after every reboot?

Mine also looks like that without showing Time without a signal for a while, at some point it will start showing 0% otherwise is will show like 50%.

That's a pretty big assumption. One that's unsupported IMO.
My "time without a signal" has been exactly 50% since I installed DamageControl. My battery life is no worse than it was with any 1.5 ROM. I don't think this is an issue.

I can tell you that my battery life for 18 hours yesterday was better then it has been. I also know that if you have no signal the battery drains like a mother. I don't know if all phones have this problem but I have a phone "without Google" on it.
ill give it a shot i was at 50% so cant hurt
I have noticed that eventhough my cell standby time has decreased the time without a signal is still at 50%.
HAHA Well without any fix at all Cell StandBy = 5% - Pretty good if you ask me.
BUT
Street View is at 89%- ROFL I haven't used Maps.Nav in 2 days!

My Time Without Signal was at 58% before doing this (the Cell Standby was somewhere around 60%).
After doing this 1.5 hours ago my phone does not display a Time Without Signal.

[Q] Help with identifying Nexus S i9020a Battery Drain

Running Stock ICS 4.1.2 on Nexus S i9020A on AT&T US.
The battery was fine till about a few months back, but of late, it is draining @ around 8-10% per hour on standby!. I originally thought JB was causing the drain, and switched to ICS, and finally to GB. But the drain is consistent across all three.
There is also accelerated battery drain if my phone is completely switched off. If I leave the battery in the phone after powering off, the battery goes from 100 - 0 in less than 4 hours. Thinking the battery might have gone bad, I bought another oem battery, but that is exhibiting the same behavior.
This leads me to think there might be a hardware issue with my phone. I am tired of keeping the phone plugged in at all times, and am ready to throw this out the window and get another phone. As a last ditch effort, I wanted to post this here to see if I can get any kind of feedback/confirmation on this before I buy another phone. Other users are reporting 1-2% battery drain on standby, so 8-10% drain is unacceptable by any standard.
I have attached some screenshots from today when the battery was at 20% after about 9 hours. For this test, I did the following last night:
1. uninstalled all apps I downloaded
2. turned off WiFi, Bluetooth, GPS, sync, auto brightness ( set to the minimum brightness)
I charged the phone fully, and then left it on standby, with minimal usage - I think I made a 2 minute call, checked my email once, and read some rss feeds for about 5 minutes in the 9 hours I tested it.

Any help would be much appreciated.
Thanks!
I know I'm not giving any advice here but I just wanted to let you know I'm in the same boat. No matter what ROM GB/ICS/JB I lose too much battery per hour with the phone just on standby. There's no explanation for %10 battery drain per hour with pretty much everything off (wifi, data, gps, nfc, background data, etc)
I have tried everything and now I must admit I've given up. I'm just going to ride out CM 10.1 until I can decide on a new phone, most likely the Nexus 4 or HTC One.

Yeah, your phone doesn't seem to be doing much while asleep. 20 minutes screen on, 35 minutes active, yet battery down to 21%. My battery would be at 90% with that sort of usage. Since you changed the battery (I'll assume it's a decent quality battery, although a cheap battery could be in cause), there's not much left.
Have you tried switching 3G off? 3G seems to SUCK the life out of these Nexus S batteries like no tomorrow.
But I suspect it's a hardware issue with the Nexus S phones. I have WiFi, Bluetooth, 3G and auto-sync all shut off and a static wallpaper and I will lose 20% of my battery in 7-8 hours.
Battery is kernel related. Try changing your I/o scheduler to row and governor to smartassv2. If you don't have those options then look for a kernel that does...air kernel and matrix should suffice.
NO SOLUTION so far
A friend was having the same issue, gave him the battery of my nexus s ... it lasted him for 7-8hrs max whereas it gives me 1 day~ on 2G and normal use without gaimng . So my guess like his mobile your mobile may have some component which is short and draining out the battery . I have been trying to look around for answer but so far no luck. So better check it with another batteryif you can before purchasing a new one.
Vampire test
If anyone is investigating why their Nexus S suddenly starts draining the battery in a matter of hours, BEFORE spending a ton of time (like I did) trying to diagnose what software problem you might have, do the vampire test, as described here:
http://forum.xda-developers.com/showthread.php?p=42586314
I wasted days before coming across this test on this forum, and it proved it had to be a hardware fault.
I have two healthy batteries, both hold a charge for days (probably weeks) when not inserted in the phone, but pop one in the phone, leave it powered off, and within 6 hrs it's dead. So frustrating, and sad to see this phone go.

Is the One X supposed to charge like this?

After switching back to ViperXL and ElementalX from AOSP ROMs, I noticed that the phone seemed to be charging kind of slow, so I went and actually jotted down some data on the charge rate.
Time, battery percentage, delta percentage, delta time (interval), percentage [points] per minute, delta ppm, fast charge, and power source. The orange dot denotes when I turned fastcharge on.

Obviously, this isn't supposed to be definitive or even scientific, but I'm curious as to if other people's phones charge like this. The whole charging process took about 4 hours from ~15% to 100% (not completely documented).
The phone didn't seem to get any warmer than usual with FC on while ambient temps were ~60F/16C.

My power source was AC from the wall. It doesn't seem like Fast Charge from the wall makes any difference (it shouldn't have).
A 90min charge is much better than 4 hours... I feel like AOSP ROMs charge much quicker than Sense ROMs, but I don't have the data to back it up.
about 100mins for mine.charge to full

trying to like my phone die to 10%, and then i will charge...it takes forever to drain for me...don't know if that is good or bad lol..been running music and making calls and keeping wifi on
I've kinda noted these issues too. The last 10% of charging takes forever on my phone, but going from 100% to 90% takes no time at all.
On the other hand, going from 60% to 0% takes forever, but charging 0% to 60% takes about a half hour.
Have you checked to see if you have an app draining battery really quickly? Usually Facebook or Google maps

So true. My led is green,and I glance it (thinking it is a notification) and it is at 90 or 91. Never recall seeing a number after that. Next time I look its blank. Which means 100 (circle percentage)

Maps is Greenify'd and Facebook isn't too high up on the list of App usage. If it was an app draining battery, wouldn't I see sub-par battery performance when off the charger? I got 14 hours total with 3 hours of screen-on time yesterday.
Mine usually takes about three hours to get to 100% from low charge (~10-15%)

Not exatcly the correct spot but, will it do any harm to charge the One X with an iPAD charger?
I remember reading two things,
1. It might harm the battery in long term use.
2. It will not charge fast hence the One X's battery is capable of pulling 1A maximum. Not an electronics expert so apologies if this is a dumb thing to ask.

I don't think the issue is that they are consistent battery drainers. The issue is that they occasionally go "rogue" and kill your battery in short order. I've had maps kill like 30 percent charge in a matter of an hour. As soon as you kill the instance, the app restarts and goes right back to its minimal usage. No idea what causes it. The entire thing is just random. I did report it to Google, though, so hopefully it will get resolved.

Doubt it'll cause damage. If the One X only pulls 1A, then it'll only pull 1A. It's not like you're forcing it to pull more.

This seems normal behavior for charging of Li ion batteries, based on the first graph here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Although the OP's issue sounds different, as the behavior seems to have started after flashing the new ROM.

Question Watch 4 stand-by battery drain

It is normal for it to consume energy at night, if you do not use the phone at night a few percent will also escape
if your battery life is low, you can try to "optimise" it (there are various tools for this on the forum)
kind regards

At night... While sleeping... So phone is not used at all... And yet the watch drains battery.
I don't know the battery lasts about a day on watch 4
and you have to charge it more or less every day
regards
I charge my gw4c in late evening, wear it before I go to bed and by the next late evening I have abt 55%. I do charge it almost every day because I know it might not make it for two full days. Heart rate/stress/snore detection set to always and blood oxygen measuring during sleep to on.

I too
I got GW5 Pro and I was also wondering why the battery usage doesn't add up. For some reason it doesn't show every apps battery consumption. I was able to find some apps that didn't show up on mine, but used some amount of battery. Usage still doesn't add up but gets closer.
On your phone open wear manager and go to watch settings and then apps. Now go through every app on that list one by one and check battery usage there.
For me Find My Mobile, Settings and Samsung text-to-speech engine shows 5% (I'm at 26% battery now) battery usage for every of those app, yet none of them are listen in apps shown at battery usage page.

That is normal. The watch is still "running" even if not on your wrist and with the screen off and idle. It is still connected to your phone and communicating some. The drain might not be a lot , but it will still use some power.

Not if it is off your wrist it isn't. My drain rate, off my wrist, with WiFi off (BT on), sitting a foot from my phone, is about 0.6% per hour.

How to even figure what's causing the drain since the battery stats don't even add up to 100? Also I noticed when placed on a dark surface, the battery drain is higher. When placed on a white surface, drain is on the lower side...

It isn't easy.
For one, it is important to store the off-wrist watch on its side or up-side-down. That is what I do. Since I have AOD on, it is often necessary to keep the display off. But it also stops the watch from trying to measure heart-rate/etc. Store it near the phone, so the signal to the phone is strong and it doesn't have to expend as much energy (assuming it ramps up/down for transmission power). Reboot the watch once in a while (I do at least once a month; I have my Samsung phone set to reboot each Sun). I am not sure what other apps or systems installed will affect battery life. I don't have Samsung health thing running, since I don't care about it.
Battery stats never add up. Not on the watch or any Android device I have ever seen.
If you use and recharge the watch (or any modern device) very often, as it gets older, the battery indicator will become less and less accurate, overstating or understating drain/remaining life. At that point, a recalibration is helpful (drain it COMPLETELY until dead and shuts itself off, charge it fully. Might require a repeat).

Well, it has bedtime mode on, so AOD isn't an issue I guess. It's relatively a new watch, been just a month or so.
Will try keeping the watch upside down and see nonetheless.

Kept the watch upside down, still drains @2%/hour.

Question Adaptive Battery or not?

So I have a new Pixel 7 Pro and after being away from Pixel devices since the 4a I am back.
I am used to turning adaptive Battery off on my Samsung devices because generally it throttles performance. Generally doesn't seem to increase battery life much.
Does Google implementation work better? Do people use adaptive Battery?
If you do why? Have tried it with it off and on and seen any difference?
Does adaptive Battery affect performance?
What are people's experience with it here?
I use it and unlike on my Note 20 Ultra all apps that run in the background like my smart thermostat with geofencing, blink cameras and so on all keep on running. On the Samsung that was always problematic. had to use macrodroid to sort of keep them running and to get geofencing working.
Battery life on the p7p is stellar too,
So most people use adaptive Battery.
Anyone with experience with it off?
I guess most people don't seem to really care?
I have never turned it off because I've never had any problems with it and I expect that with it off, battery consumption would greatly increase. Admittedly I have never tested it though so maybe that's what I'll do today.

I'm running Android 9 and 10 on Note 10+'s. I never use it as it doesn't work. Turning that junk on isn't the same as hand optimizing the phone, not by a long shot. Even with degraded battery at about 80% of its original capacity I get 9-10 hours SOT.
How long does it take charging time for you? I put it at night and it gets charged after 6 hours? Is it by purpose?

Yes, it remember your usage pattern. It will try to complete the charging process around time you wake up in the morning. Like, in my case, it will only hit 100% around 6a.m

that's adaptive charging not adaptive battery
There was an issue with losing granted permissions when adaptive battery is on. I still have it happen sometimes.

well, that's because am answering the question about the charging from user above me, lol
No one mentioned adaptive charging, i thought maybe albsat had got the 2 functions mixed up, my bad.

So are you saying that "adaptive charging" has been the reason for the late charge? My goodness. I will try today. I thought I had a defective battery. Lol
@otonieru thanks man.

Yes it times the charge by when you will be unplugging it in the morning or whatever so that it will reach 100% when you're ready to grab it. I have that option office cause I just wanna charge as fast as possible in case it's needed unexpectedly. Adaptive battery so far works better than whatever the equivalent for Samsung was.
From what I understood from Google documentation : Adaptative charging will hit the 100% charge, few minutes before your alarm time. For this feature (that is supposed to protect the battery) to work, you need to have the alarm setup between 6am and 10am.
This actually seems quite good without adaptive so I'm just going to leave it off. In fact I was doing some 5G speed testing using Network Signal Guru on this charge and I would have expected something more like 10-11% screen on drain as a result. It was hovering around 6% before that testing.

Very helpful information. Thank you!
I have had both adaptive features enabled since I got the phone from Google.
Charging speeds seem just like normal? I didn't know the longer charge cycle is only enabled if you have an alarm set on your phone? I use a regular alarm clock but I may try and set my alarm as I charge the phone tonight. Would be interesting to see if it does something like a trickle charge.
It says adaptive Battery learns your usage patterns and optimized charging speeds based on that so I just thought that was it and every time I have charged the phone it seems to charge pretty quickly and get slightly warm. Depending how low it is around an hour to an hour and a half.

If you have your alarm set some time up to 10AM, it stops charging at 80% and then trickle charges to 100% right before your alarm goes off IIRC. I don't use it because I don't have an alarm set before 10AM lol.

I am going to leave it off for a week and I'll report back with my results. So far though, it almost seems better to just leave it off, which is weird.

Gookill Adaptive battery never worked going back to Android 9.
You can see its status real time; Developer options>standby apps.
When off all buckets show as active and their states can't be altered. When on the bucket states vary and can be manually altered, which doesn't seem to do a damn thing except use more battery and cause erratic behavior especially with bluetooth apps.
Instead, target the hogs individually, altering background battery/data usage in individual app settings doesn't invoke adaptive battery or alter the standby apps bucket state.
They call it Gookill for good reasons. Lol, every dumb bunny thinks they win with Google...

I have generally found adaptive Battery only throttles performance but doesn't really offer a significant benefit in battery life. My experience with it has generally been tied to Samsung devices though so I was curious if there was any difference on Pixel devices.
I am of the opinion that if you let a chip work as fast as possible it completes tasks faster than throttled and that actually helps with battery life. Basically throttling may give you a slight battery advantage but the difference is generally insignificant but the hit to performance is generally real. So you get almost the same battery performance but better overall performance without any adaptive Battery features enabled.
It will be interesting to see the results of your test to see if my experience is true or if Google has implemented a version of adaptive Battery that actually works and gets better over time.
