Hello! I've been using my Asus ROG phone 5 for about a week now. Much like many people I have felt my battery life was not up to the mark. However, I flashed the latest firmware and wiped my phone clean, after which battery life improved substantially. However, I was on a voice call on Signal with 2 other people (voice-only, no video at any point in time. The call lasted for approximately 3 hours, and I was in an area with perfectly fine signal (all full bars). If it helps, I am using Airtel's 4g LTE connection. The screen was also mostly turned off during this time. I was using a pair of earphones (OnePlus buds Z) but I don't think that's the issue because it was only in use for the first half hour, after which I turned bluetooth off on my phone. I also use it to listen to music regularly, and I've never had a battery drain of such magnitude. It might yet be a Signal problem, but I have faced some situations which lead me to believe that it is a phone problem.
Here is my battery backup on another day, on heavy use-case. I've been away from home, and because a lot of my work takes place on the phone I've had to use it quite heavily. No problems here.
Here is how much battery Signal took up. Here you can see that it took up a whopping 32% of a 6000 mah battery in over 3 hours. Note the timestamp.
Here you can see when the call started. The call lasted for about 180 minutes, give or take 10 minutes.
Here we can see that the battery chart is more or less normal, approximately up until the point where I used Signal, and then it goes on a steep decline.
Not sure if it helps, but here is the memory usage for Signal.
Okay, so I believe that it is not a Signal problem as me and the other 2 people I was on a call with, are all running the same build of Signal, however they have different phones. More importantly, however, I have noticed battery draining extremely rapidly when I am running multiple operations on the Play Store. I shrugged it off at the time believing that I was being nit-picky, but I think that this phone's software is unoptimized when it comes to the inbuilt radios, i.e battery drains quickly when lots of data transfer is going on via the mobile network. I am not sure if this problem will persist even on a Wi-fi network, I have not checked yet.
I would like to know if this is a recognized problem and will there be a software update to fix this? I have seen other posts complaining about battery life, I believe that this may be related. Any response would be appreciated, thank you!
