I have a Curve 9360 with the latest 7.1 OS (Updating didn't solve my problem).
Problem I'm having is that the phone does not report the correct amount of battery life remaining. I've tried running it till it's completely flat and charging it overnight to make sure it had a "full" charge but within 30-60 minutes of use it shows that the battery life has dropped from 100% to 1%.
I can use the phone for hours at 1% till it actually dies. Like yesterday, unplugged from the charger at 6am, by 7am it said the battery was on 1%, battery had only really run flat at 9pm. I've tried enabling and disabling the power saving feature but it didn't make a difference.
Is this a fault with the device itself or the battery? I don't have another battery to test unfortunately. Will this issue be covered under warranty? If so, how long would it take to get swapped out or repaired (Vodacom)?
