I recently bought a HTC Radar and I love the phone. One of the reasons is the terrific battery life. Or, that was a reason. Recently my battery life has dramatically diminished for a reason I cannot find. I used to be able to do 2-3 days with a battery, and suddenly I am down to 10-12 hours (and that?s not making calls, opening websites etc.). I don?t know what the cause is; I haven?t changed any settings, all I can remember doing is updating my phone via Zune. I however don't know how that could be the culprit, No errors came up during or after the update. To ? unsuccessfully ? find the problem I have tried the following:
1. First, I checked for software updates via Zune. None are available (I am at OS version 7.10.8773.98, firmware version 1750.0602.40504.61).
2. Although I didn?t change any settings after updating I tried to set screen settings to medium, set e-mail synchronization to each half hour, disable wifi, location and more of these standard tips. This helped nothing (I tried them separately).
3. I turned off all background activity of my apps and I got rid of any live tiles for apps. When this didn?t help I removed all apps that run in the background (and that do not have the option of turning off the background activity). Unfortunately, also this didn?t help.
4. I - of course - tried switching my phone on and off. I also tried a hard reset. This had no effect.
5. Finally, I tried to roll back my phone software to the one restore point I have. Unfortunately I got an error in the process, indication that a roll back was not possible because it wouldn?t be compatible with my phone anymore (code 801812E0).
This last option unexpectedly greatly increased my battery life. I thought I was there, but I discovered this was only due to the fact that my SIM card was still locked and I had no mobile connection. After putting my mobile (and data) connection back on my battery life is back to its poor self, not making it till the end of the day (without making calls or visiting websites). Because my battery was good without the connection I assume it?s not a battery problem (i.e. hardware) but that it must have something to do with my mobile/data
So, I've been trying for quite a while and with no success. I'm lost at what to do next. Any help would be most appreciated.
