Severe battery drain forces HTC to put a hold on Android 4.4.3 update for AT&T HTC One (M8)

Severe battery drain forces HTC to put a hold on Android 4.4.3 update for AT&T HTC One (M8)
HTC has halted the Android 4.4.3 update that it had been pushing out to the AT&T HTC One (M8) since Wednesday. Users have been experiencing problems with severe battery drain following the installation of the update. Android 4.4.3 has already been sent out to Sprint and T-Mobile HTC One (M8) owners, along with European owners of the phone.

Because Android 4.4.4 is mostly a minor update made up of security fixes, HTC has taken the Android 4.4.3 update, and has added minor improvements from Android 4.4.4. This means that Android 4.4.3 should be the last update for the HTC One (M8) before the major Android L update is released.

Besides Android 4.4.3 and the aforementioned security fixes, the update includes optimization for Wi-Fi, Bluetooth and cellular connectivity. Applications getting updated include the Camera and the Gallery (Image Match), Settings (Power History) and the HTC Sync Manager. Also receiving updates are the BoomSound speakers, Motion Launch and Quick Settings.

No word on when HTC plans on re-starting the Android 4.4.3 update for the AT&T version of the HTC One (M8). We do expect Verizon owners of the phone to be receiving Android 4.4.3 shortly. Big Red customers with the HTC One (M8) will finally get the Extreme Power Mode with the update. This feature allows users to limit the phone's capabilities to making/taking phone calls, sending and receiving texts, and manually checking email, in order to extend battery life. Each 1% of battery life remaining will last 3 hours with the mode on. In theory, using the Extreme Battery Mode will allow 8% of battery life to last a 24 hour day.

HTC has had battery issues for years and for this to happen doesn't help its cause. I stopped buying HTC phones because of their battery issues

My M8 gets me 3-5 DAYS of battery life, it is safe to say they fixed the battery problems

”Each 1% of battery life remaining will last 8 hours with the mode on. In theory, using the Extreme Battery Mode will allow 8% of battery life to last a 24 hour day.” - that math doesn't add up

HTC looks like they are priming themselves for a Microsoft acquisition, so who really cares?

Yup, it's pretty ridiculous. My phone is almost unusable. At least, now, I know that I'm not the only one. I was feeling bad that my phone could have been broken.

Samsung and LG are the future of Android in the US at least. HTC devices are to heavy by far. Most people put their phones in some kind of case anyway. If you need "premium" materials ie metal. Buy a metal ingot

Yesterday I relocked my boot and unrooted SuperSU. I used the RUU exe from HTC's support. It says to have HTC Sync installed but I don't and only have the drivers installed on my 8.1 machine. It ran very quickly with no problems. After first boot I did a factory reset and cleared the cache. I then turned off FastBoot, I disabled all of the bloatware, and only updated the things I wanted to. I let the phone update while I made all of my personal settings. Next I turned the phone off and did the battery Calibration while plugged into the charger by holding all 3 physical buttons down for 3 mins. I let the phone charge to 100% then turned it on. I did a couple of restarts. It's been 12 hours and I'm still at 80% battery. Half of the usage is from me surfing the internet for a few hours last night... -Shane
