Less than 4 hour battery life

I just got less than 4 hours of battery life. Is this normal even under intensive use?
For the first 1/4 of the time, I had the phone in my pocket. For the second 1/4, I was playing Symphony of Eternity, a simple 2D RPG that looks like an SNES game, and a bit of Greedy Spiders, another simple 2D game. By the time I was done (a little past half way through the graph) I was already at half charge.
I then disabled wifi and turned off my phone and put it back in my pocket. The battery use decreased, but only by a little. At the end of the graph, I got alarmed by how fast the battery was draining and rebooted my phone, and when I restarted, there was the abrupt jump down in battery.
Anything jump out as a red flag here? I took a look at the Android OS bug thread, and it sounds like that is what I ran into, but does this seem like short battery life even for the Android OS bug and the amount I used it?

Battery drain problems

My gpad the wifi version running Android 4.4.2 got problem in retaining battery. It drains about 4 to 5 percents of the battery when the pad is in idle for about 10 hours. The pad is new so i don't think is the app i downloaded that is causing the problems. It must be something have to do with the manufacturer. Are you folks having the same problems? May be i need to flush it and reload the android to get away the apps installed by the manufacturer. Any ideas? Thanks.

Sound better than average to me (I've had quite a few tablets&phones ... but only have this GTab for 2 days).

that is actually quite good,mine use to lose 10+%.got it to only lose about 2-3% by using clean master.just kill everything when i go sleep.give it a go.

Thanks will give it a try. There are just too much possibilities here. Need an expert to figure it out.

Download App Ops Starter from playstore. Look for apps that keep your tablet from going to sleep and turn off that setting. Also you can turn off their ability to spy on you.

Slow charging and heating

Despite this phone being just perfect in every other way, a couple of things​ about it is just frustrating the heck out of me. I don't know if it's just my device or if this is a normal thing, but my Pixel XL charges SUPER slowly. Taking about as long as an iPhone to reach 100% on low percentage and 40 minutes to an hour with 50% and above. My 6p charges faster than this using the same charger. Not only that, but my phone gets really warm when charging and slightly warm with general use. Does anyone else experience this?

I experienced just yesterday. Normally the phone charges about 1% every minute for me, but yesterday it was 1% every two minutes or something, got really annoyed, turned off the phone, charged normally! And yes, there was a little bit of heat too, nothing complaining worthy but it was there, but then again I use a full back case, which I will remove shortly. The phone/SoC has some thermal throttling surely, cause several times I noticed the phone's performance would drop down severely while charging.

Extreme Stand By Battery Drain

Normally my stand by battery drain is no more that 0.5%/hr. For the last week or so it's been REALLY bad. About 2.5%/hr.
It looks like the cause of the drain is Android System and Android OS. I have tried restarting and clearing app cache on the Android System, Google App and Google Play Services but the problem remains.
Here is last nights results. Battery should be at maybe 97% but instead it's all the way down to 84%. I'm still on the June update and haven't installed any new apps in several weeks.

I lose about 5 to 6% in 15 hours standby

My standby drain is fine but on Android P DP4 I have noticed the google play store showing up for about 1.5 - 2 hours of battery drain. Anyone know what that's about?

Got 0.4%/hour last night with DP4.
Edit:
Having issues with uploading screenshots. Will try again later.

[Q] New Z2 play from China has huge battery drain.

I bought a "bargain" Z2 play from a China seller, and find it drains battery in about 7 hours.
drain occurs out-of-box with no updates. Flight mode doers not help.
Box was opened, I assume to flash international firmware. Phone is not "Play protect certified", so no google pay. Netflix works, but had to be side-loaded.
https://www.coolicool.com/cell-phon...cta-core-55-inch-corning-gorilla-glas-g-48042
Utilities report around 600mA with screen on, over 400mA off & idle.
So charged, screen off and idle, phone is warm and runs flat in around 7 hours.
settings->battery does not show any apps with high usage.
XT1710-08 PVT1 Android 8.0.0 with 1st June'18 patch.
Anything to try before attempting RMA to China?
Should I try another firmware, or would that void warranty - if a Coolicool china warranty is honored.

A few days later, after numerous tests and factory resets, the problem suddenly went away.
About 1.5hrs into a 5 hr test in standby, the logs show the drain suddenly stopped.

Problem has not been seen since, even after firmware reset.
Any ideas? I hope it is permanent.
