2 days ago it started with it on the loading times until the 100% have been shown, have been getting shorter. Caught my first not on, if it was not extremely shortened term would have been added. Meanwhile, holding out the battery no longer in Standby 2-3 hours, charge is only possible when the mobile hanging for several hours on the power supply. But that seems at some point to revive the dead battery, he invites a few minutes and shows 100%. A short time later, only in standby, the phone is as mentioned then just back out.
Sure, the battery is not GEADE expensive and with a reduced duration at an advanced age one must always expect, but as a total failure, I find it very annoying!
