Why isn't my phone battery staying charged for as long as it use to?

HTC One M8 Battery Drain After Android 4.4.4 or 4.4.3 Update

My battery used to last about 20 to 30 hours and after the recent Verizon software update for 4.4.3 and then 4.4.4, the battery has now dropped into the low 10s (12 hours on average). Has anyone had this problem and know if there is a way to fix this? I have not downloaded any new apps and all the app settings stayed the same prior to the update. I have Tasker on my phone, which seems to take the most battery after the update. However, I have noticed that Chrome is eating up a lot of battery as well when I'm just browsing.

Welcome to Android Central! For troubleshooting purposes, it can be helpful to do the following: Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:

1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

You could also try wiping the system cache partition, which won't erase any personal data: http://forums.androidcentral.com/ht...ow-reboot-into-stock-recovery-htc-one-m8.html
