iPhone 4s battery life is only 5 hours with new battery

My battery seemed to die after 4 hours, so I replaed the battery.

Now after a full charge I still seem to get only 5 hours.

The only thing running is phone service, Facebook notications and messenger.

I did notice the phone getting warm, but not hot to abnormal.

Any suggestions on what the problem may be?

Thanks

Where do you get the battery from? Maybe the battery has been used or it is a fake one. Suggest you choose a reliable supplier like hcqs.cc to get a original iPhone 4s battery.

It is worth buying a battery from a reputable supplier, eBay batterys can be all over the place.

But you would expect even the poor quality battery lasted longer to start with.

I would do a hard reset (DFU ) https://discussions.apple.com/thread/526...

Make sure you back up first

After restarting turn off everything that uses battery power. wi-Fi, Bluetooth. See how long the battery lasts for.

If you still having problems, probably you need to a get a repair shop to test the draw from logic board.

The only thing that makes it last longer now is to turn the 3G off.

Now it lasts 6 plus hours.
