Search for "Battery" in the Windows Store and pick up one of the free battery monitoring programs that displays a graph of you battery usage by time. (The one I use is called Battery Sense, by Vasan Jiaramaneetwesin).
Let that run in the background and try to remember what apps you run during the day. The graph will show you what rate you're using your ...

Is there any difference in the battery consumption when my background is black and when it is white?
That actually depends on the type of display you have, and hence on the exact model of your phone.
AMOLED displays light up each pixel individually, with the amount of energy required per pixel depending on the brightness of the colour that the pixel is displaying. A fully white pixel will consume more energy than any other colour, and black pixels consume ...

The battery life span won't be negatively affected by turning on battery saver. Reducing the current flow out of the battery (which is effectively what this does) might even be better for the battery since the number of charge cycles per week will be reduced.
Microsoft advises against turning on battery saver all the time since it prevents background ...

Some people say that it is better to charge the battery of any mobile
device after it is fully drained. But, this is applicable to nickel
cadmium types and when it comes to lithium ion, it is not necessary to
fully discharge the battery before charging it. This is because when
the charge reduces too much, it might cause damage to the device.

The battery in the Lumia 920 is not user-replaceable. If you attempt to open the device and remove the battery, you may damage your phone and will void its warranty. To have the battery replaced, take your phone to an authorised Nokia service centre.

Windows Phone 8.1 has two built-in ways for viewing battery percentage:
In the Action Centre - swipe down from the top of the screen and the percentage will be shown right underneath the battery icon, next to the time and date:
In the Battery Saver app, under Settings:
You can either pin this app to your Start screen or open it from the all apps list.

The new battery saver app introduced in 8.1 should show you battery use by app since you last rebooted the phone. On a phone that has just been turned on, it points a finger of blame at HERE Maps and People; obviously your battery usage will be different, and activities like chatting Cortana up will use a fair amount (after all, speech recognition isn't ...

Your suspicions are indeed correct.
Most, if not all, dual SIM phones (not just WP, but Android and the simpler, more basic, Nokias (101, 107, 108, etc.)) tend to use (roughly) about 19% to 30% more power, when the second SIM is inserted. This is because the phone has to poll twice as often to the local phone transmitter. If you are in an area that has poor ...

I use this app (https://www.microsoft.com/en-us/store/apps/battery/9wzdncrfjc2z) called Battery.
It does everything I have ever wanted (only used Windows smart phone) and I find the statistics really useful.
I then pin it to the home screen and it gives me updated battery statistics.

I have had the same problem with my Lumia 950XL, check the Settings -> System -> Battery saver, tap on "Battery use".
But I notice that in my case the wifi turned on, and the signal switching from 2G-3G-4G causes battery drains and even resets. But it is related with bugs of the OS. The latest version 10.0.10586.107 fixed some of the problems but not all ...

High battery drain after updating to WP 8.1 is not an isolated problem its all over the forums.
I'm pretty sure this is the problem with geofencing.
Geofencing is a new feature in Windows Phone 8.1. The phone keeps on checking your location continuously even though the app doesn't require it. Example IE, WhatsApp, etc. (pretty much any app).
This is just ...

If you are running out of battery where you cannot finish the day without the phone dying, having a replacement battery you can swap out will not damage the phone at all as long as you purchase a suitable replacement. In fact, this has been a common practice amongst business users and a complaint about many high end phones which tend to not have replaceable ...

Even with all the usual suspects taken care of, my 920 will sometimes get warm out of nowhere and start draining battery like crazy. I suspect some sort of firmware issue. In any case, when that happens just do a battery-pull reset -- hold the volume down and power buttons until the phone vibrates. I have to do this a couple times a week; an annoyance, but a ...

Yes, using different USB chargers should be no problem.
I have many different Nokia, Dell, Apple, etc USB adapters and use them to charge different devices all the time.

You can't find things in such details but yes we do have some to get details like those. You can try a view to your All settings->Battery saver.
Here you will be able to see your battery status, then usage of apps. You can allow and disallow them too according to your need.
We windows users are happy with it :)
You as a long time android user will find ...

This can be done with a custom app that doesn't use the built in phone email function I believe. I use the below vode in my .net desktop apps and i think similar will work on phone. But I don't think battery percent is available in Windows Phone 8. Only 8.1+. In Windows Phone 8 you can only detect whether it's charging or discharging iirc.
You can have the ...

Do You have other devices on your network? If so, it's connected to your phone and if You have a lot of devices connected to That network it'll automaticly connect (or trying to connect). Try deleting These devices. Then restart your phone and done. If it didn't work, There'll be a software/phone issue.

Use Battery X app (Free or Pro), its best for windows 10. the live tile also show the battery percentage with remaining standby time.

It has mostly to do with how Mobile Networks work. Each connection results in the cellular radio being on for 10-15 seconds after the transaction. If you get over 12 e-mails an hour - polling every 5 minutes is more efficient than push. However, if you only get 1-2 e-mails an hour, push is more efficient. I blogged on this (with some math to corroborate). ...

The LG Quantum C900 uses a lithium ion battery. If you run it completely dead it can be irreversibly ruined. However, the electronic circuitry is designed to make it more difficult to drain. It is designed to "shut off" the phone when the battery is around 2-3% charge remaining. The battery will still naturally discharge and it is possible for it to ...

I advise you to plug your phone to a charger and then begin with update. During update to W10 battery percentage can go wild (my Lumia 520 went from 90% to 10% during update, and after update it had around 40% battery) or it can get stuck on last(or any other) step for a long time.
Play it safe - plug it in and do not worry about the battery.
P.S. When I ...

My summary of the referenced links below:
Check your storage available, you need up to 1.5 GB free space. New phones allocate System & reserved 4.98 GB of 29.1 GB. You may also have some pre-installed Apps & games taking up space (mine was 1.05 GB). If you have plenty of storage space available then you can ignore the erroneous storage space ...

I use to have the same problem. Then updated the phone to OS build: 10.0.10586.29 and all seems to work fine although the phone gets hot when I am using it while it is charging.

I'm sorry my answer isn't direct (as others said, this is a question for a hardware-reviewing site, of which there are many varying opinions), but here's my take:
The technology of the battery itself has not changed very much over the years. Largely, the time that the battery will last you is dependent on how many programs run in the background over time, as ...

The first weeks I had the same problem, but at some point, after a month or so I did't experience this problem. I turned of some background services for a while, but now I use sync every 15 minutes and allow all kinds of background services. I think you have to use it for a while for it to be great!

Pull uses less battery power as it checks for new email messages at a (specified) regular interval.
Using "push" email however allows message to arrive on you device virtually instantly. In order for this to work, your phone needs to keep some form of constantly network connection online

No, that won't hurt the battery at all. You're fine.

It has been my experience that Windows Phone "always" has a rough first day or two after a major update or a restore. I've reset various phones of mine on a somewhat regular basis and the following day always seem to be an irregularly bad battery day.
If the trend continues, I would use various battery monitoring tools to track down the situation. It is ...

Following Perrucci, Fitzek and Widmer (2011) WLAN is more power efficient than 3G. A publicly accessible excerpt of their results can be found on their website. Note that in their study, the access point was placed fairly close to the cell phone.
The same conclusion has been made by Carroll and Heiser in their 2010 USENIX conference contribution, measured ...

Third party chargers are known to be of significantly lower quality than name-brand chargers. I used a Samsung charger with my HTC 8x that ruined the battery within a month and bricked the phone.
