If you're using android 4.4.4 goto Settings>Battery, then up the top right hand side click on the battery icon. This should bring a drop down menu to change the battery symbol.

I had a similar issue with an S4 mini. I found the best solution to turn off airplane mode and then turn on wifi, which essentially keeps it from searching for a cell signal when one was poor or non-existent. You can create reminders or macros to do some of this on a non-rooted phone.

No, It is not possible on unrooted devices and yes, it can be done on rooted devices. In a rooted device, Add a permission to Android : android.permission.WRITE_SECURE_SETTINGS. Then, system call the set function of the BATTERY_STATUS_CHARGING from the BatteryManager with a 0 value. To automate this function, use a third-party application like Tasker to ...

Sounds like you could use a factory reset. This will reload your operating system. After you do that I would load applications one by one and see if any of your apps are causing the battery drain. Here is a guide on how to factory reset your phone: http://www.digitaltrends.com/mobile/factory-reset-galaxy-s5/

There is a bug report that has been filed to AOSP about this with a FutureRelease status (a bug fix will be coming soon). Read it here. It seems that a reboot provides a temporary fix for the problem. A factory reset fixed the issue permanently for most users.

I upgraded to Android 5.0, and now the option to hide battery percentage is available with a simple checkbox in the battery settings interface.

Here is the official documentation. It's very simple, just take off the back cover and pop out the battery.

You should have no problems doing it on your own. However, make sure you use a compatible and genuine battery to avoid issues. Switch off the phone before proceeding. Pop the back cover and replace it. Turn on the phone and check for any charging defects. (just to be sure)

On smartphones I have never seen any problems in doing it yourself. Be a little gentle though when you remove the back cover of the phone. Some of them can be very thin plastic thus a bit fragile. My own Samsung is very thin overall. OBS: Never ever use any tools other than your fingers ;)

So the battery usage information is usage since the last time you unplugged at about a full charge. Something is going to use the battery. People worry too much about "why is using 40% of my battery" but that is not actually the case. It is using 40% of the about of power that has drained since you unplugged your phone. So if your battery is at 90%, and ...

There is a free guide available on ifixit.com: https://www.ifixit.com/Guide/Nexus+5+Battery+Replacement/26009 Of course, when disassembling the phone you always take various risks of damaging it, but I assume you are aware of that.

If the battery depleted without a phone shutdown call, it would essentially be the same as a battery pull, where the power is suddenly cut off from the device. One of the major risks is preventing this automatic shutdown is data loss/corruption, but this should only occur if you were in the middle of a data process (eg. saving offline document, ...

Instead of paying for Tasker, the same things can be automated for free using the app Automate. It has blocks for checking battery level and rebooting the device. However, rebooting a device programmatically will required a rooted device.

Do you have an external sdcard in your device? If so, remove it and try again. When sdcards start throwing errors and have to remap sectors it kills their performance. As this is usually an indicator for a dying sdcard i would suggest to backup any important data you have on it.

The extra connections on the battery are for an NTC thermistor within the battery so the phone can monitor the battery temp. How else do you think the phone can display the battery temp? Std on iphones, some Androids can also display it with the right software installed but it does monitor it during charging etc to protect the phone and battery from fire ...

It isn't airplane mode.... airplane mode only stops certain hardware from running, making it physically impossible for that to be the reason You probably have a bunch of other applications running when you go to sleep. but it will always say that Android OS used the most battery, because the operating system handles everything... try installing cleanmaster ...

Had the same situation, I rooted and installed some app management apps, and stopped autoruns of many apps like maps, games, etc. I also removed some stock apps that I don't use which runs in background like Samsung apps. I recommend "System Cleanup" app for this .

and after restarting the phone battery is empty. This shows the battery of the phone is dead. You will need to replace the battery to stop the sudden drain like this.

Batteries labeled NFC come with the NFC antenna, without which it would be impossible for the NFC chip on the device to operate.

I have an OTG adapotor that looks like this It accepts SD, microSD and USB memory sticks while charging. It's a bit bulkier than what you've got, but it may be worth trying. This one was made for the Galaxy S2, and it works well with the Galaxy S3 and the Galaxy S5 as well (those are the ones I've tried it with, and it probably works with most Samsung ...
