Phone shuts off when taking pictures with flash.

This has been an issue for a long while but its frequency seems to have increased now. Basically it happens randomly and only if picture is taken with flash. I have experienced it on both stock jelly bean ROM and cm10. I don't remember it being an issue on ICS or GB. My phone is not over clocked and the issue does not seem to be affected by kernel.
My gf also has a nexus S and same thing happens with her. We both have the i9023. Her phone is completely stock and not rooted.
This problem is also not limited to the stock camera app as I have experienced it with camera zoom fx as well.
Anyone else with the problem? Do you think its a potentially hardware issue with nexus S?

I think your problem has something to do with your batter. This is my theory because whenever you try to take a picture with flash on a faulty, or non-calibrated 3rd party batter, the phone shuts off. Try this: take out the batter, plug your phone in to AC, and take a photo with flash. Let me know what happens

What is a third party batter? I am not using any "third party" thing. :S
And this problem isnt easy to reproduce since it doesnt always happen. It just randomly happens and I can go on taking several pictures with flash without a problem. Actually what I have noticed is that it will happen on the first or second click in a session or it wont happen. If the phone shuts off and upon reboot I immediately take a pic with flash then it will shut down again but if I give it a break then it wont.

Yeah, the same thing here. Must be a 4.2.1 issue. Happened to me on 2 different roms. I never take that many photos, but happened a week or so and didn't think about it. But today needed the flash for Christmas pictures and every time I used the flash the phone shut off and I had to power back up. What rom are you on?

I am running cm10 stable right now. This is a jelly bean issue I think and I dunno why its not reported enough because its quite a major issue if you ask me. Nothing more embarrassing than that happening in front of friends. :thumbdown:

I forgot to mention that sometimes it wouldn't shut down, it would render the touch screen unusable and I had to pull the battery

Thats not happened with me so far.

It's the cheap battery
My phone switches off when I take picture with flash but only if I'm using the cheap battery which i ordered with spare charger. Tried the cheap battery with my brother's note 4 and it happens every time. It never have or has happened with original battery. This is one of the tests for a new battery.

Inconsistent battery fixed by reboot

I have been so impressed with the battery life on the N5 however the last 2 weeks my battery is dropping 50% in less than 4 hours. If I reboot my phone it fixes this and drops about 10% - 15% in 4 hours.
I thought it must be an app I am opening that is constantly running in the background but can't see anything obvious.
Anybody got any suggestions or advice? I have stopped almost all apps and uninstalled the majority. I don't want to restore factory defaults if I can help it.

Have you checked Gsam? Mine sometimes does that, and the culprit normally is my kernel keeping the phone awake for whatever reason, and a reboot solves it. Not sure why though

Get betterbatterystats and see what your wake locks are.

I have gsam but not really sure what to look for?

I'm not familiar with that. Does it tell you what your partial and kernel wake locks are?

If you go to App Usage it will give you a breakdown of what apps are using your battery

I have this exact same problem. I normally have to reboot my phone when I disconnect from the wireless charger. I don't think that's always the cause tho. I would love to install batterbatterystats but you need root am I'm really trying to not go down that road anymore.

I think It's the dialer. I had this problem in 4.1.1 where it would constantly be looking at my address book in exchange.

In my case, Gsam points to the Kernel being the issue. I'm trying out a different kernel, and haven't experienced the same issue.

App still draining battery after uninstalled?

I have been using the app tweetcaster and it started to drain my battery, maybe off an update or something. So I uninstalled it and downloaded another twitter app, fine and dandy. Only thing is I checked my stats and com.handmark.tweetcaster is still draining my battery!! This is absolutely murdering my battery life! Any help would be awesome, thanks.

Keep that screen up and plug your charger in and then disconnect it. Plug it back in and see if its still there.

Weird. Try clearing your cache.
Sent from my Nexus 5 using xda app-developers app

The only thing I can think of, if clearing the cache doesn't work is that it did not uninstall correctly. Try going to your Settings -> Apps and swipe over to All. make sure that process doesn't exist in that list. It sounds like it did not uninstall correctly somehow.

How exactly do I do this, I know how to clear cache on a specific app, but not one that's uninstalled
Sent from my Nexus 5 using xda app-developers app

Have you charged your phone to full since then? The battery stats aren't cleared until a nearly full charge. That's why it is still showing.

That is bizarre. You could try clearing cache as others suggested? Are you running stock or custom recovery?

El daddy's post is correct. The app is not still draining battery.
The graph shows battery usage for 10 hours.
If that app had shown 40% after 5 hours and your battery had gone down to 75%. You uninstalled it at 5 hours. If your battery was at 50% after 10 hours It would still show as 20% after 10 hours. Even though you uninstalled it 5 hours previously.
Just charge your phone back up to full which will trigger a reset on the usage calculator. All should be fine after that

Nope I uninstalled it last night, I reinstalled it about an hour ago to see if it saved any cache, but it didn't, so I uninstalled it again. Phone was completely charged to 100% for this morning

100% stock, phone has not even been rooted yet. How do you clear cache, I know how to clear cache on individual apps, but this app is no longer installed

To clear the cache partition:
Turn your phone off.
Hold volume down and power, this will boot you into the bootloader.
Scroll to recovery using the volume keys and select recovery using the power button.
It will boot into recovery and you'll see an android laying on its back. Press and hold power, then immediately press volume up and let go of both. (it may take a few tries as it's tricky to get right. If you can't get it in time, the phone will reboot and you'll have to start over)
Once the menu opens, choose clear cache partition. It will wipe cache and the phone should reboot automatically.
The boot up will take more time as usual as the OS re-builds cache.
Hopefully this helps. I'm not sure it will work because I've never seen an uninstalled app drain battery, but it doesn't hurt to try.

Okay cool thanks. I use to ROM and everything when I had a captivate, and galaxy s 2, but this phone is so polished and smooth stock I never saw the point to. Didn't know I could get into recovery without being rooted with a custom recovery installed. I'll do this when my phone charges to about 50%, its basically dead right now

Incorrect/Unreliable battery reporting?

So I was charging my N5 and rebooted. As you can see, the reported battery level jumped ~25%. I am under the impression that "battery calibration" apps don't do anything, but should I try something to fix this? Or am I wrong about calibration apps?
Sent from my Nexus 5 using XDA Premium 4 mobile app

na, just use and charge it like you normally would, itll work itself out the next 1 or 2 charges. its been like that since the first day android was public with the g1, and every device after. its not perfect, but its usually pretty accurate. when its not, it generally works itself out quick. only rarely are their other issues involved.

Massive drain with no wake locks

Hey all
I had a wake lock trigger that was draining my battery so I decided to try and find what was causing it. I turned off all background sync and disabled GPS. I charged my phone to full and then let it drain over night. As you can see in screen shots... Massive drain occurred with no visual signs of the cause. Anyone have an idea?

Did you get any shots of the Kernel Wakelocks and Partial Wakelocks screens in bbs? That's where you would see the culprit(s). Also, do you ever do soft reboots? Some people (including myself) have experienced increased battery drain with no visible wakelocks after soft rebooting. Doing a full reboot seems to fix it.

It's definitely something using Wi-Fi. Need more in depth analysis

I checked those but there was nothing abnormal. I'd done a reboot when I flashed the kernel back to stock pa.

I've disabled wifi and it drained to dead. Going to recharge to full and see what it does off wi-fi. What could I do to see why/if wi-fi is killing it?

You can see it is draining it in your screen shots. Maybe you didn't fully disable the background Wi-Fi usage. "scanning always enabled" for example

Doesn't look like its disabled correctly. Your screenshot shows nearly 8 hours Wi-Fi.
Maybe there is a bug in your settings data.
Not sure if you're rooted or not but maybe a backup / wipe is the best course of action

Here's the current setting. I guess I can factory reset again. I'll try that after this current charge cycle.

You could try booting the phone into safe mode to see if it's a 3rd party app, though unnecessary if you plan on trying a full reset anyways.

Factory reset, no syncing enabled, no auto updates, google now disabled, no apps other than stock gapps installed. Still high android os usage.

while at first it looks high, in reality it isnt(yet). in your screenshot you have only lost 5% battery so far with light use. at this point you really cant tell what your battery will be like with use.

ahh, thats a little better, but itll drop a little more with use. while 20 is a little high, id still classify as normal. really anything up to 20% is normal. typically, after a full cycle, i see android os between 9-15%. but it would all depend on exactly how you use your phone.

i see that chrome(and chrome sandbox) is taking a huge amount of battery for very little use. 21% together, just to respond to xda..

Install system monitor from play store and check CPU freq and number of CPU's online while screen on.

As said above....use the phone normally and check when its almost drained. It will surely be much lower.
If location is on...it will probably be higher than 10% I'd guess. If so....completely normal.
