Hey guys,

My M8 has severe battery drain issues. It went from 85 percent batter to about 25 percent in the course of 2 and 1/2 hours and all I've done is sent a few texts. It's been like this since I bought it two days ago, right out of the box. I've flashed Android Revolution Rom and that didnt help.

Settings, apps, running, and see what's running. Install wake lock detector and greenify. Let wake lock run a while and greenify the bad apps. You can also go into app permissions and deny a good many wakeups but you have to pick and choose cause you can prevent the app from working.

Also choose a governor other than interactive, like on demand and noop or sio for scheduler.

Also turn off WiFi and anything else if your not using it, location especially.
Good luck.

HTC One M8 powered by SinLess Audiophile v3.5.5/Elite Lunar 3.4.0

Could your other posts about converting to AT&T or needing a VZW radio zip have anything to do with this? If you flashed something incompatible, there is a pretty good chance that's causing your battery issue.

"I figured it out. For anyone else out there that has a Verizon M8 and are using it on AT&T, you can convert your phone to the AT&T variant. I'm getting LTE but not constantly, it switches between LTE and HSDPA but it's staying mostly on LTE. Yay!"

If your signal is bouncing around, that will kill your battery.

It was like that out of the box before any modifications actually. The first day I got it I charged it up and it drained to zero within about 4 hours. The second day same thing. I have to charge 3 times per day just to get through a whole day. And that was before I even rooted, did S-off, unlocked bootloader or flashed any roms. After having it for a couple of days I converted it to an international device to get lte (which I'm getting) and the battery is the same as before I did anything. No change. Drain drain drain. It also charges very slowly about 4 to 5 hours to go from zero to 100 percent. I've even tried turning the mobile data completely off and connecting to my wifi at home and even with mobile data completely off it drains the exact same. I think my unit is defective.

If it did that from the beginning, I would bet on a hardware issue. I don't get battery life that bad even with heavy internet use and streaming on WiFi.

Thanks. I ended up exchanging it for a new one and the new is fine. I get a full day with heavy use. Yeah the other one it was really crazy. I would have to charge 3 times a day, it was insane.
