I received my replacement C550 replacement, Tuesday 19th.
It was charged for fully 16 hours before I began using it on Wednesday 20th
My usage on day 1 saw the battery drain from 100% @ 06:30 to 60% @ 16:30 (loss of 40% @ 4% per/hour)
My phone was synchronised with PC on The Wednesday eveing thus charging it as well, I guess for a period of approx 45 minutes.
Phone turned off overnight.
Phone battery level at 51% when turned on at 07:00 Thursday
Down to a critical level of 5% as of 11:20am on Thursday
Thats a loss of 46% in a 4 hours 20 minutes (approx 11% per hour !!)
The call times as of the time when I had to being recharging on the Thursday were as follows:
Total of 1 hour 10 minutes and 43 seconds ( Yes - virtually nothing !!!)
Broken down as 16:09 Incoming, 1:46 outgoing and 52:48 data
During all this period of time - Bluetooth has never been activated and signal has always been reported as full strength
At this rate, which can only be described as light usage - the battery would only last a maximum of 25 hours a minimum of 10 !!
Suffice to say I have been on to OCS & upgrade department. Upgrade deferred & C550 (second one) being returned.
I really did hope the the first instance of the battery life being poor was going to be an isolated case, as I could have got used to living with the C550.
Unfortunately though the second one has suffered from the same problem and it is somethign I personally cannot live with.
A bit frustrating really.
I can see by both by the lack of issues with the C550 being posted here and elsewhere - coupled with the postings of support for this handset - that my case is probably a one off.
I'd really like to hear from other users if this turns out to be something a bit more widespread.
Now......wheres my faithfull C500............aaahh, back to normality.
Any views are welcome.
