Build 14342 is draining the battery like crazy!

Hi,  after the update my Lumia 640 goes from 100% to 40% in < 2 hours. The battery used to last a full 24 hours before this update. Looking at the Battery Usage by App shows Settings at 35% (I looked at the settings for < 2 minutes!). Need a fix for this issue soon. Thanks.

5/19 Update: Installed .1003 yesterday and it didn't help at all. It looks like the cellular radio is constantly looking for a signal and is causing the phone to heat up. With all the heat build-up and the rapid discharge, I am afraid that the battery's lifetime is going to be severely affected.

5/25 Update: Downloading .1004 right now.  Thanks for the update. Hopefully this fixes the battery issue once and for all!

Glad to report that .1004 has fixed the battery drain issue!

The same on my Lumia 930 - and it's overheating!!! Please fix it fast.

I have Start, Store  & Settings listed as main battery consumers. Phone is Lumia 532.

On 24h profile: Start-17%, Store & Settings-10% each.

On 6h profile: Start-20%, Store-13%, Settings-2%.

This is the option "Apps with usage". If I change to All apps then it is only Start(17%) & Settings(12%). All the rest are below 1%, except for Outlook Mail-2%

I have aout 40 tiles pinned to Start. Cellular was never on since I installed this build 14342.

In regards to the Store drain:

After Store got updated I cannot check for updates-the button remains unresponsive with the new version (11604.1000.21.0). Anyone else having the same issue with Store?

Have A Nice Day!

me to. lumia 640xl. never seen bat drain like this with any other preview build.

Hopefully the new build 14342.1003 just released will fix this.

Yeah hoping for a fix with .1003. My phone doesn't even last 4 hours from full charge with 14342.

Thanks, but already tried this one. Store wouldn't install with error code. Then my battery was almost down, so I connected the phone to a charger & few minutes later got a notification that Store, Maps, OneNote & Microsoft Health were updated.

Thank you for the suggestion though.

Have A Nice Day!

same. Please report back here when you have some more info.        

Grr.

After my Lumia Icon got this Build, I noticed it was hot in my hand. I did a full shutdown to see if it would cool off once restarted. It warmed right back up after I powered it up. That's when I noticed the battery draining fast and it draining as fast as I could charge it. So, with some free time to mess with it, I went back to 8.1 Mobile, made sure everything was working fine, then turned Fast back on.

After the Build loaded again, I thought it was fine for a while and the battery was recharging normally... and then a friend called me. While I was talking to him, I noticed the phone getting hot again. I looked down and the battery was draining again.

I am back to Windows 8.1 Mobile again.

I hope this helps, Microsoft, and that you can rush out a fix soon. With as many Builds as you have sent out, I would think this kind of silliness would be a thing of the past. Maybe your developers and testers need what my dad used to call "a stern talkin' to."

Same here with a 1520. Only my 2A charger has enough grunt to charge it, 1A or USB can keep up. 

Drains is about 3 hours and is very warm around the camera area. 

During this update, I did notice the reports of the windows logo staying on screen for a long time, I also experienced that, but I updated before work, left home at 8, by 1pm I still had the windows logo on screen (I plugged in at work to ensure the battery wouldnt go flat during the update because it was taking so long). At 1pm I decided to reset it by holding the power down. It booted up ok, but that afternoon reported an upgrade needed to restart my phone, I did that restart also and got the cogs and windows screen but it was much quicker.

After all that it when the massive battery drain started and 50% of my apps say "<appname> cant be opened. An app update may be available in the Store"

Not good. Please fix ASAP
