got the battery to 100%, its been unplugged for 2 hours and its at 65%...and thats without data, all background stuff disabled, no extra apps on it, no 3g, and the wifi crapped out earlier today too
That specific description definitely sounds like a hardware problem to me, I would guess either the battery management module or the battery itself. Hope the replacement is OK, please let us know.
I strongly dout that the facebook app is causing this issue as i have it on all 3 of my wp7 devices. I have all background tasks turned off. I have changed the setting on my googletalk app (forget the name but if makes a diff i will post here) to not push notifications. I will let you know how this test proves.
I've found WhatsApp really sucks the battery down. It's difficult to turn off push notifications with that though because it would kind of defeat the purpose.
My experience today is as follows:
Charger off at 6.30am. Wifi off. Bluetooth off. One email account (30 min sync). Location services on. Find my phone off. Facebook and google logins added.
So far made one phonecall (a few minutes), sent 5 or 6 txts, surfed the web for around 30/35 minutes. Checked the phone now and again (new emails etc), probably about once every 30-60 minutes on average.
Remaining battery life is 49%
Estimated time left 12 hours
Time since last charge 12 hours.
Its now 7:28pm. So it looks like the phone can work ok all day given my normal usage, will see how the web surfing goes as I leave work and head home.
Does this Lumia sound healthy?
Hello, all. Get the lumia one week ago and I have the battery troubles also. Called nokia support and they promised an update. But i don't know what to do, because i can change my lumia for 14 days for another....I like the system and phone but the battery life is really really poor. Can anybody tell me how to set the find my phone mode off?
After having discussion with a friend about this picture and the fact that i coudn't start the phone, He said me to plug the provided charger, not using an usb port from my pc. I did it, and after some time, I could start it again. So, I'll continue to test, disable background tasks.
I have the same thing with regard to "full capacity" - 1500mAh max, but remaining charge, when "fully charged" (reporting 100%) doesn't get above about 1300mAh.
I suspect what it's talking about is that the battery's full charge is 1500mAh, but the *remaining charge before it turns off* is 1300mAh. This would fit with keeping 200mAh charge minimum on the battery as Lithium Ion batteries *really* don't like being fully discharged. So the 200mAh is likely to be a 'safe' minimum to keep the battery working right, and so when reporting to the phone, 100% is 1500mAh, 0% is 200mAh.
