I read that report. I mentioned it to HTC and Verizon. They said, "Well,
Europe has different systems than the US." I did not believe that either.
Just another excuse to not take responsibility for these problems.
Beg my pardon if these solutions are not helpful to you, but these two temporary fixes have greatly curbed my 4.4.2's battery drain. Essentially, these two changes are to ensure your phone can go into what android refers to as 'deep sleep mode' when you are not using the phone.
Disable your wifi (I've never gone over a gigabyte despite 4g connections while watching youtube and using the browser)
-Settings->Data Usage->(top right dot menu)->check 'Restrict background data' (things like weather will not update automatically anymore)
'Restrict background data' must be unchecked to use the Google play store; however, you won't be using the store much in the first place if your phone is dead.
Even with these "fixes" the battery drains the same. I turned off
background data, WiFi, Bluetooth, I don't use the phone for anything other
than email and phone calls and Facebook Manager. The battery drains faster
than before the update.
THIS WORKED FOR ME:
got an email from HTC support, which I will copy. so far, my battery is back to normal.
I totally understand your concern on this matter with the battery drainage of the phone, and I will be more than glad to assist you.
I ask you to please go to All apps > Settings > Battery or Power, and disable Fast boot. Then, please go to All apps > Settings > Developer options, and enable USB debugging. After doing this, please perform a Cache reset. This process will delete unwanted and temporary files from your phone. It will not mess up your personal files. Just follow the instructions on the attached file.
COPY OF ATTACHED FILE:
e:can’t open /cache/recovery/command
HOPE THIS HELPS ALL Y'ALL (as we say in SC)
I tried this solution on my HTC One yesterday and thus far it has worked. The battery is lasting longer; the battery is only at 50% after 24 hours in contrast to 4% after 8 hours before the fix. Thanks!
@padinjones - I have a two month old HTC One M7 preloaded with Kitkat 4.4.2 that received a "baseband" firmware update on Thursday, June 5. Whereas I was getting the advertised 5 days standby time, losing only 2-3% charge on my nightstand overnight, I suddenly had to charge my phone 2-3 times a day and it would drop 55-60% overnight, EVEN IN AIRPLANE MODE!!!
When I called Verizon to complain they seemingly could not get that phone out of my hands fast enough and fedexed a warranty replacement for Saturday AM delivery. To add insult to injury, the phone they sent me was not new and it was DEFECTIVE! Would not read the SIM card! When I called AGAIN to complain they had me try a master reset on my phone. After a day's worth of reloading and configuring all my apps that still did not solve my problem.
YOUR SOLUTION WORKS! Thank you so much for sharing what the (removed) at Verizon cannot seem to figure out. HEY VERIZON, ARE YOU READING THIS???

Then perhaps your tech support can start sharing valid solutions now instead of trying to mask a non-hardware problem by being triggered happy to send out refurbished hardware? I will be very curious to see and track how Verizon handles similar future complaints. We are watching..............
