Hello together,
I´ve also the problem, that the battery of my IP5 drains out to fast. My IP5 does not reach the specifications.
I can not use LTE, my phone is in 3G with perfect radio conditions.
Yesterday, I made some tests with my IP5.
I found out: Running WLAN in parallel with having 3G Data connection = on seems to drain out the battery of my IP5 in unusal high manner.
After releasing the 3G Data connection and running my IP5 only in WLAN for data, the phone reaches the specifications in extrapolation. After one night in standby and some phone calls / mails / Push= on / surfin during this morning: the usage time is much less than ever before related to my use cases. 16 hrs standby, 1hr 10 min. usage, 87% rest-capacity. Values, I never reached before, regarding my usage profile. Extrapolations for 3G call time is nearby 8hrs, as expected by specification.
For sure, this is no solution. But it indicates for me, that the HW / battery of my IP5 seems to be fully okay and perhaps, there could be a small software problem causing unusual demands from the mobile transmitting unit, especially when WLAN = on.
Let us see, what will happen in the near future ( SW-Update?)
