I have resisted updating my Android firmware and am still on V19.
Up until a few days ago, I always got a day's battery life - even with CODI enabled.
Now if I leave it unplugged sitting there doing nothing (WiFi on as normal), I can pick up my phone and it isn't responding. Turns out the battery has drained and it has turned itself off. I estimate it is losing 25% charge in a little over 2 hours.
I haven't changed anything with the setup on the phone - nor have I installed any new apps.
Any ideas or is this just another Planet quality & reliability issue?
On mine, there is something that occasionally causes the CPU to max out and the battery drains very fast.
There are a couple of tell-tales for this:
* Temperature goes way up in the area near the fingerprint reader
* Screen refresh rate is impacted, looks very jerky when sliding from one desktop to another (or any scrolling, really)
To counteract these, I always check if scrolling looks jerky before I put my phone away, and I have set up temperature alerts.
Between these two measures I usually catch the problem within a few minutes of whenever it starts (you can see very clearly when it starts in GSamBattery's charts, the CPU goes to max, the battery drains fast and the temp starts creeping up).
If I catch it early the battery drains by just a few percent capacity, so I still get a full day on one charge.
This happens around 0.5-2x / day, ish.
Very much looking forward to the battery improvements in V22, whenever that comes.
