[Q] Battery life and Android OS drain bug

For anyone using Android 4.0, specifically running it as stock on this device, do you experience the same battery drain issues commonly seen in Gingerbread? You know the one where the process Android OS uses an ungodly amount of battery life through suspend and events/0?

been playing around with the phone for the past 8 hours from a full charge, nothing unusual about the battery
tomorrow with normal usage after the full charge i'll get a better view about it

Does it take long to charge the battery? Like the nexus s. If its a slow charging phone like the nexus s then im not buying.

didn't think that fully charging it toke that much
i usually leave the phone charge when i go to sleep
removed from a 100% charge at 9:15am GMT

I own Nexus S too and experience the same, slow charging ... using the charger from Samsung (default).
So, I changed the charger and I use the one that came with the HTC Desire
And it is much faster, like 3 hours to go fully charged compared to more than 5 hours.
So, there you go, change your charger!

I can usually get my nexus S to a full charge in an hour or two, depending on how empty I let it get. It's fast enough that if I've forgot to charge & need to go out a 20 minute blast will get me through the evening.
No idea who made the charger.. I've got a house full of the damned things these days

So what about life time?

Just check your chargers mA output, the higher the nr, the faster the charge. A computer USB port outputs 500mA wich gives a rather slow charge normal mA on chargers is around 700mA -> 1A. Keep in mind though that higher mA resulting in a faster charge puts more stress on your battery and it WILL get hotter, to high numbers can even damage your battery so be carefull and monitor your batterys temp when trying a new charger!

Slightly off topic, but regarding charging...
Does charging via a "weaker" USB port damage the battery? For example, at work, the only USB port available is an old iMac keyboard USB port, and it's "weaker" in the sense that when I connect it to my phone, the computer tells me "A USB device needs more power.... "
I understand this might charge the battery slower, but does it cause any damage to it, short or long term?

As far as i know USB before 2.0 needed external power supply, meaning your device should not be able to charge from this type of USB. But to answer your question, no, you can not damage an electric device by undervoltage or lower Amps.

Hope to get the GN soon.
Like to see and test how the charging is with different chargers.
Have seen slow charging ( also better hold out ) with different chargers.
My best charging is stil with the original desire ( charges quick and battery holds longer ).
Galaxy S plus is slow, wildefire also slow...

Phone charging really slow??

So my s2 has been charging really slow, like today it took like 5 hours to fully charge, and when connected to charger if I'm using it it wont charge very well, like the battery will stay at lets say 20% when im using it and charging it, it might even go down more. it used to charge pretty well even if I was on it. Cuz this be the charger, or is my battery messed up?? Im using the charger that came with the phone.

Are you charging through a usb port on your computer or ac? If it is with usb port then yes it will charge at a much slower rate. Also if you have a lot of apps running or backround data going it will also cause your charging to slow down some. I would say through usb without any apps open and backround data stopped It would take a few hours to charge say from 20%. Through AC in the same condition probly 1.5 hours. Try to reboot your phone and then plug it in to charge to see if that doesnt speed it up any. If it does then you know you have backround data moving at a fast rate and that would be your reason to slow the charge down.

Yeah I'm charging with the wall charger, not thru usb

You could try calibrating the battery, maybe. To do that, turn the phone off. Charge to full (make sure it's full, by taking it off of the charger and putting it back on...the indicator should read 100% almost immediately when reattached to power).
When the battery is full, with the phone still turned off, remove the battery for about 2 minutes. After 2 minutes, reinsert battery and restart phone.
Battery will be calibrated. This may not resolve the problem of a slow charge, but will clear 'battery memory' which may have been preventing it from charging completely (and, I suspect, may have inhibited charging).
Good luck!

I was using an aftermarket wall charger and had similar results. Switched to the USB/AC converter that came with the phone and all was well.

Actually, one doesn't need an app to calibrate the battery. If you follow the instructions above, the app is unnecessary. And the phone mustn't be rooted

YODA? ^^^^

Hey elflip88, have you found the issue yet?
I have the same problem on my HTC Amaze 4G. It's charging 1% every 3 minutes (adds up to 5 hours)
I'm also using the wall charger...oh damn, I'm starting to think I have a faulty device / battery...
yelp!

For the record Samsung devices are known to be slow at charging so with that considered.... You still shouldn't be at 5 hrs. I would find a battery stats app charge your battery over night and check the chart to see exactly how long it takes to go from 0 - 100. Make sure your batter status is good. Also check the voltage coming into your phone from your charger. There are plenty of battery stat apps in the market that will do this sort of thing. Of course make sure your battery doesn't have water damage of course too lol.

I've had the same problem with mine. But, I can get 1.5 days without charging and moderate usage. Charge it up, drain it, charge it back up then wipe your battery stats in recovery.

This may help if you're using an aftermarket wall charger
If you guys are having issues with slow charging using an aftermarket wall charger, it could be that the phone is charging in a USB state rather than an AC charging state. QuickCharge could alleviate your issues. The cable is inserted between the wall charger and the USB cable that goes to your phone. You can find the product on Amazon. It's the 2nd of 3rd item from the top when you search 'QuickCharge'.

I find that when I fully drain my battery and charge it, it's really slow. Once the phone has enough battery to stay on, I unplugged it and replugged it and it charges normal again.

It's your wifi and your apps using wifi. Turn wifi off while charging. I used to charge 4 hours + on my S2. Reduced to 2 and some change when I turn off wifi.
Also, I struggle to make it through a working day with wifi on. Turn wifi off and I can do 4 days no problem.

USB to PC

I would try another cord and/or a different pc if possible.
Also check the battery stats to see if a certain app takes up a lot of battery (it may restart the app as soon as you kill it).
If none of that works I would wipe and re-install the rom or another rom for testing purposes.
And if it occurs on multiple roms/kernals it maybe hardware/battery related.

i believe you shouldn't charge it with a PC usually. i could be wrong though.

Not necessarily - in my experience it depends on how much power your computer's USB ports are capable of providing, and even that can vary depending on what controller is powering what ports and the like. I normally charge my phone from my computer and it takes roughly the same time as using the wall charger, though I've noticed that it doesn't seem to charge as quickly on at least one or two other computers I've had the phone plugged into.

USB usually has 500mA, where as the charger supplied by Samsung has 1000mA. It -will- charge faster with the supplied charger.

That is still sufficient power to run the phone without the battery. So at worse, the battery stays at the same percentage. It's not normal for the battery to drop while the phone is plugged in.

Higher powered USB ports are far and few inbetween. Usually higher end PC's/controllers will accommodate this. Most PC's though only push about 500mA via the USB ports.

once in while my phone will bug out like that, even if you turn it on and off. only way to really fix it is a battery pull.

I have found that if I am doing anything on it (screen on, gaming, Internet, etc.) and connected to my laptop, it often will not have enough power on the subject to compensate for what I am using and will only slow the speed the battery decreases.

That's crazy. Try a factory install. Another possible point of contention, lock frequencies and stop all overclocking. On custom Roms is your clock/governor settings set in the rom OR an app? If you have both set to boot they could be conflicting and constantly switching clock speed and governor settings.
Another thing to do. Charge to 100%. Go into recovery and delete your battery stats

yeah.. that's happened with me while pc usb charging. i was running maps, playing music, and texting at the same time with the screen constantly on. at first it was a slow drain.. then if i turn the screen off it would charge.. just too many things at once. but governor, voltages, schedulers do play a factor.

I don't think you guys realize. I don't have a single app running. At lunch time today I basically had 95% charge on my phone -- and it was connected to my computer.
In about 5 hours the ONLY thing I did was send a few txts. Sent maybe 20 txts in 5 hours. The ENTIRE time my phone was plugged in.
My phone is now at 84% and it's super hot. Opening battery to see what's up? doesn't show anything using any battery juice.
This phone fuking sucks.

What is it that's getting hot, the very bottom of the phone or the battery?
Have you tried going to retail store with this problem and see if they swap out the battery for you? Might just be a faulty battery.

I just had the same problem with my brand new stock Galaxy S4.
I bought the new 2amp Genuine Samsung car charger and on the 1st use with my phone turned off it took 3 hours to charge 49 % battery and when i turned the phone on it would say it was charging but the battery was going down.
Faulty cable. Used the car charger with cable provided with phone, all fine. But the Galaxy S4 with auto brightness even with the genuine wall charger if you are playing games it takes ages ti charge and sometimes won't even charge and loose battery.
Just use the genuine charger and try not to use the phone while charging.

10 hours to recharge phone ??????????

Can anyone tell me why it takes so long to recharge my phone ?
I use a charger cable from my computer (usb) to phone while at work --- then I also use it at home too.
Is it only the wall charger that does it fast ? not USB/laptop/computer ?
Last night it took me 10 hours (phone was on but I didn't touch it for 10 hours - internet/wifi/3g was OFF)
why does it take 10 hours ?
Is something wrong with the phone? battery? or is it the charger ?

USB only has a small amount of current that goes through it. Enough to power small USB devices and no more. I believe it's around 500mAH. But your phone is always drawing power, so the excess is what actually charges your battery. Your wall charger is 1000mAH which means there is plenty of current to charge your battery even with heavy usage.
Tl;dr: USB is weak and 10hrs is normal. Wall charger is much more powerful and faster.

damn thanks for the great reply.
Further more, I was at my friends house once, and he has a black berry (same charger as my SGS3) and he passed me this cord to charge and it honestly charged the entire phone from 5% to 90% in like less than an hour...
not sure wtf this was but is it possible ? is it bad for the phone ? for the battery ?

10 hours is not normal. And the average wall charger that comes with your phone is 750mAH, not 1000. The 1000mAH chargers are quick charge ones.
The fact that the blackberry charger worked well on your S3 tells me that you should get a new charger.

where does one find one of the quick chargers to buy ? (1000mAH)

you can find all sorts of chargers on amazon. you can find inexpensive ones at walmart too. i would recommend buying a samsung charger for your samsung phone. hold onto the one that came with your S3, even if it takes forever to charge. just use it to connect to your pc for file transferring, odin, etc.

Even though charging quickly seems good but if you can afford the time then use the one you already have z charging too quickly affects your battery health negatively , a slow charger will make sure your battery stays healthy for a long time , mind it by slow I mean a 750 mAH one not a faulty one in case yours is faulty .

The S3 charger is 1000mAH. I have two of them that came with my phones. And anytime I connect my phone to my computer I can leave it connected for hours and only charge a few percent. This phone just draws a lot of power.

thats interesting because i have 4 samsung chargers. 2 came with my old S2's and 2 came with my 2 S3's. the output on all 4 is 700mAH. i got robbed. of course, connected to a PC the output is max 500. even at that, i still get a better charge than a few percent when connected to a PC for hours.

Navigation app KILLS the battery?

Anybody else having the issue (or perhaps it's normal?) where running the Google Navigation app on your Nitro absolutely KILLS the battery...Even if you have your Nitro connected to a high-output power connector?
On mine, running CM10.1 RC5, even plugged into a 1.0A car adapter, the battery drains at about 1% per minute! The area around the CPU is super hot so I imagine running Nav pushes the CPU quite a bit...But this seems excessive.
Any thoughts on workarounds, fixes or alternate Nav apps?
Thanks.

This is actually a fair question, as what is "normal" usage when it comes to using Navigation on our Nitro? Is the 1% per minute drain to be expected?

What IS normal is high current draw during battery use. What ISN'T normal is the battery drain when plugged in. Try a different cord or even a different vehicle. I have noticed that on some cars for me it won't charge at all, but won't drain, and on others it will charge slowly. I would suggest also making sure that the cord is rated for at least 2 amps. When I tried the stock cord and charger with a power inverter it would drain the battery with GPS use, just not as bad as you described. Also with screen off I get a drain of about 5%/hr with the navigation working. This has been consistent with stock or cm10.1 for me
Sent from my LG-P930 using xda app-developers app

it's actually decided by the wiring in the vehicle, and the adapter (which is either a car plug that has usb or a straight car plug -> micro usb)
i drive 3 differant vehicles at work and my car and have 3 differant adapters, i noticed that each adapter has differant charge speeds, and each vehicle does as well, my dollar store charger can't even keep up with navigation drain, a rapid charger will. however in my car i have 2 outlets, one in the center console and one in the dash, the center console outlet is more powerful than the dash.
so if u can't control your vehicle power buy a higher priced rapid charger.
if you really want good charge, buy an adapter that turns your car plug into a wall outlet plug, then plug the wall charger that came with your phone into it, that will probably be the max possible current you can get in any outlet, the higher quality the wall outlet converter the better.
if you notice you can charge your phone in a wall plug about 5x faster than a cheap car adapter plug
that is why they added a "slow charge" warning in some rom's to hint to people that it isn't the phone that is broken it's that there is a LOW current coming into the micro usb port.
there are also some kernels that will force a faster charge and remove some media transfer over usb capabilities, but i think that only works when plugged into PC (not sure)

I've noticed mine drain like this too. Nav annihilates my battery, if it's plugged in it still slowly drains. Maybe someone still running a stock ICS ROM can try it for comparison.
My old phone (HTC) also drained fast on nav, but plugging it in would result in a VERY slow charge instead of a slow drain.

The only time I experienced an actual drain when plugged in was while using the stock adapter on a power inverter. My car adapter plugs straight into the micro USB and us rated at 2A that is why I suggested a 2A adapter. Also to answer mpsantiago I experience no battery drain on stock ICS but on cm10.1 it actually charges faster. The only thing I can say is get a 2A adapter as the phone clearly draws more than the stock 1.2A adapter can deliver.

that's interesting... well i guess the moral of the story is just find a good charger, usually dollar store ones are garbage, also, use a widget like power toggles which has a multi setting brightness toggle, and turn your brightness low while your screen is staying on in navigation, my only suggestions. you could also try a new ROM or flashing firmware for gps hardware but i doubt that is worth the effort, if i use a cheap charger or use a bad outlet on an old work truck i have these problems with ANY ROM, but i don't have them using a good charger.

I love this phone and all, but it tends to have strange battery drain tendencies. As in, the screen isn't what drains the battery most, a lot of the time. :/
I happen to have the 6200 variant, if that makes any difference.

I had installed the yahoo weather app and went from 2 day on one charge to less then 8 hours on a charge. Some apps are a bastard on the battery..

Yes, Navigation kills battery. I too have it plugged into my car charger and while it slows the drain down, it can not charge it fast enough to keep up with Navigation's drain.
I'm running HO!NO!'s ATT V20f rom with the latest Wind Kernel. It's not just your phone. The Nitro gets hot and if you didn't have the car charger plugged in while running Navigation, your battery would easily be dead in about an hour.

You have to use a 2 amp charger with the navigation app with the screen on. As part of my job I am constantly using Google navigator. The cord I purchased was $40 and it charges fine, slowly but fine. To test this I borrowed a buddy's cheap charger that he bought at Walmart and sure enough I experienced battery drain, as it was only rated at 1 amp. The good news just hit the power button on the phone to turn off the screen. You will still get the voice guidance and your phone will charge or get a decent charger. BTW my charger has charged my phone no matter what ROM I used from Gingerbread to Jellybean.

good advice, but if you need the screen because of volume issues or you don't have a bluetooth stereo to make listening to audio easy, then you can just turn your brightness down as far as possible, i use power toggles for this its a widget with a brightness button that has up to 4 options, so you can push it and toggle through, mine is 10% 20% 30% 75% and there is a settings for auto, this is handy because depending on the sun at the time you want to be able to quickly swap between the lower brightness settings to find one suitable for seeing but that has minimal battery drain.
