soft reset in whichever state the phone is, which is in essence a battery pull.
hard reset while turned off, which starts you over without data (so back it up if you go this way).
Other phones probably have their own instructions on doing this; if there is somehow no way at doing this, the only thing left to do ...

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 ...

I decided to do a bit more testing on a Nokia Lumia 800 running the 12072 firmware.
I did a basic test using the Nokia battery diagnostics application.
I found that when using as items arrive the battery discharge would wildly fluctuate between 80-420 mA, with long periods of around 280 mA. Changing to check hourly the discharge was reasonably calm at ...

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.

1) Go to Setting, Swipe to go to the applications tab. Select background tasks and turn off every background task which you don't require.
2) Don't use applications like flashlight and others very often which may drain your battery.
3) Keep your WiFi and Cellular data off when not in use.
4) Turn on battery saver.
5) Set brightness to automatically adjust....

The Windows Phone OS has been built from the ground up to manage power in a newer, unique way. For one, like you mentioned, a push notification system. This system is designed to circumvent the old way of having to expend power by polling a server.. especially since most of the time there wasn't anything new there. However, not all services offer it at this ...

According to this article it appears that the latest firmware has messed up the Battery Status icon as well as the application, consider looking for a way to downgrade or attempt to contact Nokia to resolve the issue you are experiencing.
I haven't read it in detail, but perhaps the battery fix I posted above fixes this (or causes this); in any case, be on ...

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 ...

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 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.

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 ...

Poor reception drains the battery very fast. Is your new providers reception worse?
You should also check your running background tasks settings->applications->background tasks. Try disabling all tasks (if any).
If 3G is on while you are sleeping try increasing the email polling interval to one hour.
To further rule out connectivity issues, try sleeping ...

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 ...

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 ...

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 ...

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.

The car charger will have the same output as a standard charger, so no problems there.
The degradation people are mentioning is probably due to the car kit frequently charging your phone to 100% which isn't good for lithium-ion batteries. I believe most phones will stop charging when it gets to 100%, but the problem will be that you may frequently turn ...

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 ...

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). ...

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 ...
