Flash disabled with low battery power. - HD2 General

Is this normal? I was on about 19% and it refused to enter the camera app, giving an error. A soft reset fixed this but the flash refused to start but is now working normally following a charge. Was this an intermittent fault or normal?
Cheers.

Yeah, this is normal, using the flash with the battery power that low is a bad idea for the battery, can cause an abnormal discharge I believe.

This is normal.The limit they made is 20/100 for battery.After that flash light is grayed out.

Always power off without low power alert

If my HD has 20% power left and is running program, it will always power off without low power alert after a few minutes. Then, you must recharge it for power on.
In addition, I found that the refresh interval of power indicator looks slow, in other words, after it has been charged and run for a while, the power indictator is still 100%.
Can anybody tell me the reason and how to resolve it? Thanks!
Are you using the original battery?
Battery level is rather inaccurate, especially with 3rd party batteries, so don't take it for granted.
The battery is certainly an original battery.
Is there a possibility that the issue is relative to ROM version?
I have a experience that I flashed a rom of version 21109 into my HD, the issue occured every time. Afterward, I reflashed a stable rom of version 20769 back to it, the issue has never occured. But, several days ago, I flashed the newest radio into my HD, after that, the same issue occured anew.
I'd blame the battery, if it dies when your unit reports 20% charge, it must be in a pretty bad shape. If you can find a spare battery, give it a try...
was anything more found out about this? I also find my battery indicator very slow to update....soft reset my device and lost 5% power according to the battery...I have even had the reverse effect after a charge,....soft reset after a charge and seen MORE power than indicated.
This is making me paranoid and search for every last tweak to save power but it might be that the indicator is wrong in the first place - ideas?
Charge the battery full and let it drain to zero,and one time again.this should recalibrate the powermeter.
or your battery is old and broken...if you often charge your device when its not even required the battery will loose power and be dead in a very short time.
i know my english is not the best,hope you understand what i mean

Unable to activate flash when taking photo [Problem solved]

This is just weird, i have been using the flash while taking photo, but today i was unable to activate flash light. I can press on the 'flash button' but it won't change into auto mode or on mode. Any suggestion?
This seems to resolve itself now. The only thing i can think of is because of low battery. The battery was around 15 % when it happened. i charged my phone 5 mins ago and it is at 21% and the flash is working again.
it looks like it auto prevent the use of flash light to save some battery when it is running low.

Nexus 4 shuts down with blue flashing light

Hello,
Yesterday, my nexus 4 while it was in deep sleep turned off itself and in order to boot again I had to plug it into my pc (wall would be ok also).
When the phone booted there was a drop in battery details from ~90% to 0% and then back on ~70% (when booted).
So, I cleared the battery stats with the battery calibration app from play store and see how it goes.
Today, the phone shutted down again, while it was in deep sleep, with a blue flashing light (from the notification led).
This time the phone booted without charging it and there was a drop in battery details from ~60% to 45% (not 0%).
I run the device full stock and rooted.
Maybe there is a defect or a software issue. I'll flash again the stock rom, do a factory reset and I'll report back.
However, I was wondering if someone knew what the blue flashing light means...
Thanks in advance for any suggestions and help

Massive Battery Drain in 4.4.2

Does anyone else have a massive battery drain in Kit Kat? I can charge my Nexus to 100% and in an hour or two it's completely dead with blinking red light. I tried restarting to bootloader when it was at 5% but it was still on for like a half hour. Once I restarted my phone, my battery read 0%. I'm thinking it may be time to change the battery if no one else is having this problem.
I suggest you to reset the battery stat from the recovery. The probability that this works are low but is better then nothing.
How do I do that from recovery?
Edit: phone was charged to 98%, rebooted into recovery to see if I could wipe stats in TWRP, rebooted again, phone reads 28%, 3 minutes later it read 66%.

To wipe battery stats in TWRP:
boot into TWRP recovery
/advanced/File Manager/
folder /data/system/
click batterystats.bin
click Delete
reboot system
If you can't see the folder, you need to mount the data folder.
Well I switched to Philz Touch, do I have to do the same thing then?

You should have the wipe battery stat under advanced in your recovery.
The right step to follow are:
1. charging the battery FULLY
2. wipe Battery Stats
3. don't charge the device until the battery still turns off your device because it empty
4. now again FULLY charge without interruption
Wiping battery stats does nothing, see here: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ . Sounds like your battery is borked. May need to send away for repair. Are you still under warranty?

Yeah I figured. Thought it was a KitKat bug at first but then it started getting ridiculous. Phone was at 70%, started taking a photosphere, phone shut off, and when I turned it back on it was at 3%.
No its not. Bought it off Craigslist. Just gonna order a battery off eBay for $18 and replace it myself, see if that fixes anything.
I just got out of a similar problem.
My battery percentage was jumping all over the place.
It would charge fully in about 5 mins, and die in about 20.
Everytime I restarted the phone, it would read a different percent.
I ended up running the phone on full brightness, with like everything turned on to drain the battery all the way down.
& Everytime it would shut off cause it had no battery left, just restart it and keep draining it until when you reboot the phone it no longer turns on(because the battery if fully drained of course).
That's when it is really dead.
Then just charge it to 100%, and keep it charging for about 20 extra minutes once it hits 100%, and now it's back to normal!

That really worked? Any problems with it since and is this a common issue with the N4? For some reason it won't die when it's in the bootloader even though the percentage read 5.
So yesterday it was so dead that it gave me the red blinking light, should I charge it when that happens again and should I leave it off while charging it or turn it on and not touch it?
How many times did you have to do this until it straightened itself out?

I am currently having WakeLock problems, but I do not beleive this was the cause.
I was able to restart it after it died about 4-6 times, till it was fully dead.
Then I charged the phone, and kept it off the whole time.
I installed wakelock detector to make sure that wasn't the problem. I had this problem on the stock rom even before I rooted. So the problem hasn't persisted since?

Nexus 6p suddenly shuts down at ~20% battery left

Hi guys,
I have a problem with my nexus 6p's battery. My phone is always shutting down as soon as it reaches around 20% left. I tried a full factory reset, different roms but the problem is still present.
The strange thing: I can't boot into android after it shut down. But: I can boot into twrp. I could run my phone for 2hours in recovery mode. I made about 10 backups and deleted them immediately.
The display was on and on 100% brightness.
Is it possible to recalibrate the battery? This is so annoying!
You probably need a new battery. Download AccuBattery from the Play Store, and use it to check the health of the battery.
Yeah definitely the battery I had similar issue. For now you could just keep the battery topped up but in time will start doing it at random times.

Sounds like a battery that's done...get a replacement...they're not that expensive.

Once you emptied it in recovery, try charging and quickly (with fast charge like 10s should be sufficient) booting then without using the phone, letting the phone charge and stay 1h30 at 100%.
Then let it discharge and when you reach the 20%, you need to have the minimum discharge rate (airplane mode, no heavy app, screen off). Every like, 30mn, check your percentage and screen off again.
Has anyone had an issue similar to mine? My issue is that the phone never shuts off when i'm using it. Randomly, a couple of times a week, i lock the phone after using it, and when i go back to turn it on, i see that the phone has shut off. I can turn the phone back on without needing to put it on a charger. Running PN + EX kernel if that matters.
