I noticed that this version of Minecraft PE (1.8.0) drains my batter more faster than the 1.1 version. I can now only play about 3 hours (from 100% to about 5%) on my phone compared to the 4-5 hours on the 1.1 version of MCPE. I'm using a Xiaomi Redmi Note 3. Hopefully this issue will be fixed immediately. Thank you.
