Troubleshooting for Nokia Lumia 900

If the battery is completely discharged, it may take several minutes before the charging indicator is displayed or before any calls can be made. In some cases where the battery is extremely low, one of the following tricks may resolve your issue.

1. Connect the phone to your computer with a USB cable that came in the sales package with your Lumia phone. Your PC should detect your phone now. If the battery has not been used for a long time, to begin charging, you may need to connect the cable, then disconnect and reconnect it.
2. Press and hold the Power and Volume down keys at the same time for 10 seconds. If this restart sequence does work, then you will feel a vibra and the phone start up.
3. Switch the phone into Connect-to-PC mode following these steps:
   a. Unplug the USB cable from the phone.
   b. Press and hold the Camera key and at same time connect the USB cable between your phone and PC.
   c. Continue holding down the Camera key until you see the Connect-to-PC symbol on the phone's screen.
   d. Release the camera key and disconnect the USB cable.

If the tricks above does not help, you will need to contact your local Nokia Care. You can find details by clicking the Contact us link in the support pages of the Nokia website for your country.

If you face such issue, try the following:

1.  Move closer to a WLAN access point to get a better WLAN signal.

2.  If possible, try to create a connection with some other device that supports WLAN (to see that access point is really working).

3.  Restart/reset the WLAN access point, and try to create a connection again.

4.  If some manufacturer specific network mode (Turbo/Nitro/Super/Afterburner/108/SRX) is used, disable it and try the basic modes 802.11b/g/n.

5.  Check that DHCP (dynamic host configuration protocol) is activated in the WLAN access point.

6.  Set the WLAN access point to SSID visible mode (at least temporarily) to check that the Lumia phone finds your WLAN access point properly, and to prevent SSID typing mistakes.

7.  On the router, remove the WLAN security settings temporarily, and try to create a WLAN connection from the phone without any security settings first. WPA2 (AES) is currently the strongest form of security offered by WiFi products, and is recommended for all uses, choose WPA2 with AES (do not use TKIP).

• If you have older WiFi devices on your network that do not support WPA2 Personal (AES), select WPA/WPA2 Mixed Mode. This mode will allow newer devices to use the stronger WPA2 AES encryption, while still allowing older devices to connect with older WPA TKIP encryption.
• If your WiFi router doesn't support WPA/WPA2 Mixed Mode, then WEP128 with Shared Authentication should be used (with a single WEP key in key index 1).

8.  Check that you do not have MAC (Media Access Control) address filtering on in the access point settings. If your WLAN network uses MAC address filtering for security, you will need to know the MAC address for your phone, and then add it to the access list for that network before you can connect. To find the MAC address for your phone, do the following:

1. Press Start, then swipe left to the App list.
2. Select Settings > About > More Info.
3. Then note the MAC address.

9.  If there are many WLAN access points nearby, try to use a different wireless channel in your WLAN access point. Select channel 1, 6, or 11 to optimize wireless performance.

10. Check if there is a software update available for your WLAN router.

11. If you are using a public WLAN access point, it is possible that all IP addresses are in use. Try to create a connection again later.

12. On your Lumia phone, delete non functioning WLAN access point (internet connection) and connect it again:

1. Disconnect the WLAN connection if connected.
2. Press Start, then swipe left to the App list.
3. Select Settings > WiFi.
4. Press Advanced at the bottom of the screen.
5. Tap and hold on the access point name and select Delete.
6. Now add the access point again.
7. On the Advanced screen, tap Add , type the network name in the Network name box, and then tap Add.
8. On the Sign in screen, type the password in the Password box, and then tap Done.
9. Tap the Back key once finished.

Many features in your Nokia Lumia phone increase the demand on battery power and reduce the battery life time. For example if the signal strength of the mobile network varies much in your area, your phone must scan for the available network repeatedly. This increases the demand on battery power.

You can set your phone to automatically save power when the battery charge level is low. To check the battery status, and switch battery saver mode on, go to Settings > battery saver. Windows Phone 8: To choose when you want battery saver mode to be activated, switch Battery saver toggle to On and tap advanced.
Note: When Battery Saver is on, your phone will no longer: automatically receive email and calendar updates, update some Live Tiles and allow apps to run in the background.

If you are listening to music or otherwise using your phone, but do not want to make or receive calls, switch airplane (flight) mode on under the Settings menu.

To save battery power, note the following: 

Background apps

1. Set your phone to check for new mail less frequently or even by request only. On the start screen, open up the email account you want to modify, and tap the three dots (...) in the right bottom corner of the inbox screen, and then tap Settings > sync settings and change the setting for Download new content.
2. Some apps may run in the background unnecessarily. On the start screen, swipe left, tap Settings, swipe to applications and tap background tasks. Tap the app you want to block, and tap block. Especially Lumia 520, 620, 720, 810, 820, 822 and 920 users; please check that Nokia Drive+ Beta app is blocked (set to Off) in background tasks.
3. Close the apps you are not using, to do that, press Back key. For example, when you are finished taking a picture, press the Back key to exit the camera viewfinder. 
   

The screen

1. Set the screen switch off after a short time, go to Settings > lock screen (Lock+wallpaper) and change the setting for Screen times out after.
2. Lower the screen brightness, go to Settings > brightness > Level. Switch the Automatically adjust to Off and select the level. 
   

Use network connections selectively

1. Switch Bluetooth off when you do not need it, go to Settings > Bluetooth, and then slide the Status (Searching and discoverable) toggle to Off.
2. Use a Wi-Fi connection to connect to the internet, rather than a mobile data (E, G, 3G, H+, 4G) connection.
3. Stop your phone scanning for available Wi-Fi networks if those are not available, go to Settings > WiFi (Windows Phone 8: Advanced), and uncheck the box next to Notify me when new networks are found.
4. Switch off location services if not needed – so the phone will not look up your location frequently in the background (Settings > Location services > Off).
5. Use NFC on only when needed. To switch the tap+send feature off, go to Settings > tap+send, and switch NFC sharing toggle to Off.
6. Switch off Connect with Xbox LIVE when you not need it, go to Settings, swipe to applications and tap games.
7. Windows Phone 8: Stop your phone connecting to Xbox Music cloud collection go to Settings > Applications > Music+Videos, and switch all relevant settings off. 
   

Anything else I need to know?

• Always charge the battery fully. Check Settings > battery saver > battery information. Note that older chargers may not fully charge the battery.
• Mute unnecessary sounds and functions, such as key press sounds and vibra. To do that, go to Settings > ringtones+sounds.
• Use wired headphones, rather than the loudspeaker.
• Make sure that your phone is running the latest software to get battery related improvements. Please check also that your phone apps are up-to-date.
