I barely use Snapchat, less than 10 text snaps per day, only one or two 300KB pictures, and I almost never watch nor send videos. I never use the rightmost activity (branded content).

Despite this very limited usage, Snapchat consistently wastes a LOT of battery:

Network usage is also way over what it should be. Data usage alone is not high enough to explain the huge battery drain though.

Just staying on a conversation screen (zero activity) drains more power than the outlet can provide. You read this correctly: Even with the phone plugged into the wall, if Snapchat is open the battery level decreases and eventually the phone has to shut down, this happened to me yesterday with a Nexus 5.

Is there anything I can do to prevent Snapchat from using that much power?

  • Use a firewall to block useless branded content download?
  • Remove some permissions? (phone is rooted)

I only need conversation with friends, which means I don't mind losing branded content, sponsored stories, etc. I don't care much about my friend's profiles/stories either.

Note: That's despite having enabled Settings > Manage > Travel Mode already:

  • I don't use Snapchat- maybe these settings help? – beeshyams Jun 16 '16 at 11:20
  • @beeshyams: That URL has two tips: the first I had already enabled, the second is for iPhone. Thanks though! – Nicolas Raoul Jun 16 '16 at 12:03
  • Suggest install Wakelock detector as explained here as first step- second step could be to limit those wakelocks coming from snapchat without breaking functionality using Amplify (requires Xposed ) – beeshyams Jun 16 '16 at 12:12
