  1. Backup your iPhone using iTunes or iCloud.
  2. Use iTunes to completely restore your iPhone as new.
  3. Setup iPhone and monitor battery usage to see if it is normal. If not, you may have a hardware problem - if so, contact Apple support.
  4. Restore your iPhone from your backup above.
  5. Check battery usage to confirm that it remains normal.

This could be due to a lot of apps and services running in the background, when double pressing your home button, are there any apps open?

Testimonial: "I have a Iphone 4s. The battery lasted me @ 25 minutes to fully discharge. I replaced the battery and now I only get @ 45 minutes to use the phone before it is fully discharged and shuts down. I replaced the battery with another 4s phone and it did the same thing @ 45 minutes to shut down from fully charged. As you recommended, I pressed the home button and there was only 1 app running. Any other idea's?"

    That is unusual, how often do you charge your battery? Also, when you bought the battery, did you put it straight into the phone and use it, or did you put it in and let it charge for a while? Batteries usual never have such a short operating time.

    It may not be the battery's fault, one of your phone's has faulty hardware which is damaging the battery's life span.

Norelco shaver sudden power loss
I hope you are observing the following:- Recharging only when the batteries are almost completely empty. Continuously recharging or continuously using as a corded razor will reduce life of batteries Charge only when the indicator in charge meter starts blinking. It appears that your batteries are gone. Hope you have replaced the batteries with the new ones. Use a good brand

My wing phone has a poor battery. I can hardly talk for 45 minute
Sometimes overcharging can do this, look online to find another battery if you think you overcharged your phone. If the phone came like this call t-mobile for a replacement if you are still under warranty if it covers batteries. I have a Wing too and it does have alot of problems.

How to unlock a cell phone
Try this. Disconnect the battery from 30 to 45 minutes. That is long enough for the capasitors to discharge and it should loose it memory. If that does not work then it is locked by the sevice provider, not on you phone, and you must contact them?

Battery
Before you change the battery:
  1. Charge the battery fully
  2. Discharge the battery fully
  3. Repeat steps 1 and 2
If the battery does not reset itself and start lasting longer then you do need to replace it.
