Hi, my screen on my new phone shows as using 49% of battery, which seems a little low compared to my previous phone which would have that value at about 70%. I'm wondering if 'Android OS' at 16% is abnormally high, or is this normal?
Also, is it possible that keeping wifi on while screen is off would cause the phone to stay awake?

So, I'm running the latest MikFroyo (4.2), Netarchy's 4.2.2 Less HAVS and the corresponding SBC kernel, and running SetCPU (set at 384/128 conservative with the screen off). When I have the screen off and the phone is idle, I'm seeing an unusually high drop in battery. Last night (12-8) my phone dropped 12%. While looking at what was using the battery up, Cell Standby and Phone Idle were using the most battery (46% and 40% respectively), Android System had used 2%, and screen had used 1%. I checked Spare Parts and I don't have any wake lock issues that I'm aware of... I checked and, according to the battery use details for Cell Standby, the phone was only without a signal 19% of the time.
Is this normal or is there something I should check out? I've never had battery drop like that overnight. I'm seeing an unusually high drop in battery even with the phone idling with the screen off.
I've done a load of tweaks to maximise the battery life of my Play, and am now getting a couple of days of light use on one charge. Looking at the percentages for battery use, I have "cell standby" and "phone idle" taking up 70% between them. Display is down at 5% even though that's the main culprit for everyone else's battery drain (judging from what I've read).
This made me think - Are cell standby and phone idle taking up too much juice on my phone, or are they just that high because the numbers have to add up to 100 however efficient you make it? On an optimal phone, should cell standby and phone idle be the biggest drains on the battery, or should display always be the biggest problem?
Yes, those should be the largest two values on a very optimized phone. The higher the "phone idle" % is, the better (because phone idle uses very few resources, a really high % means the other apps are using almost no resources). And yes, they all always add up to 100% (it may be a little off because of rounding). Also, "display" means the phone is on and in use, while "phone idle" means the phone is on but the screen is off (so depending on usage, either one of these could be higher)
Hello everyone! I just switched to my first Android device and am truly enjoying the experience. I can't believe I was using an iPhone for so long. I finished draining my battery for the first time and recharged it and am draining it again. My phone indicates that the screen is consuming around 66-70% of the battery drainage while everything else is quite low such as the Android OS taking up about 12%. Is this typical and does it improve over time? Thank you for your help.
this is normal but seems like that is pretty heavy use. if your phone was barely used then that is not normal.
I am going to further diagnose this. I have my brightness set to auto. I wasn't really using the phone that much. I flashed it to the yakju build and it is running 4.0.2. Is there anything I should do to test the phone?
what is your screen on time
I'm looking at
9h 56m on bettery
Android OS 33%
Phone Idle 30%
Cell Standby 22%
Screen 9% (on time 9m)
Wifi 5%
Google Services 2%
This is after the phone being nearly untouched most of the day, no calls or texts and nothing being done but checking my email once not too long ago. It's on Auto-brightness which sucks because it appears to be on the darkest setting but without that my battery seems to go from full charge to 50% in 1-2hours with moderate usage (Browsing the web, Checking email, Browsing Market, few phone calls and texts) and it sucks that I feel like I cant play with the phone because it'll be dead when I need it and without Auto-brightness the battery dies even quicker.
Almost feel like I need to be tethered to the charger.

you either have really bad signal and/or 4g and/or a process keeping the phone awake, in your case the high cell standby time suggests the first two
This seems common for the lte version. The gsm version gets very good battery life especially idle drain. Turn off lte is your best option.

Assuming you have the screen on a lot then yes. Those big beautiful screens are hard on a battery.
If you're on the LTE version using 3G only you will get around 3 hours screen on time MAX.
GSM version you will probably get 3-4 hours screen on time per charge.
Hi guys,
I've recently bought a Nexus 5X. Naturally it came with Marshmallow installed. When I turned it on it was at 19% and I've used it for a couple of hours and the battery charge barely dropped, I was even concerned that there might be an issue with either the battery, or the phone reporting the charge properly (it just looked too good to be true).
I've charged the phone and updated to Nougat. It seems like the battery is discharging rapidly. I've followed tips like never let the phone go under 10-15% and charge for 2-3 hours longer, after the phone reaches 100% for the first few charges. Now on its 4th charge it still drains rapidly fast. When I use the phone (adaptive brightness off, I'm using it at 20% brightness at the most) and the battery drains really quickly and it looks like the screen is at fault. When I play something it's ~1% per minute or two, which is awful. Here are some screens:
It seem like I don't have enough posts in order to be able to post links in my threads, so the phone's charge is currently at 27%, the screen has used 22% of the battery - Time on: 2h 58min / computed power use: 567mAh
As a comparison my crappy old Sony M2 Aqua (I know, I know...) for the same battery usage by the screen I can see more than 7hours "Time on". I know we're talking about different devices, Android versions, screens, etc, but it still looks like the battery of my Nexus 5X is draining a lot faster than it should.
I must admit that the battery barely drains when the phone is at standby (locked screen).
So is this a software issue with the new OS, or a faulty screen, or battery or something else? I'm really freaking out guys, please shed some light on this if possible.
Hi
My A52s battery don't seem to last long, upon checking Always On Display was consuming 16% of it. Thats a little excessive isn't it?

That is impossible to say. The 16% is the AODs part of the total consumption. It is NOT, as many believe 16 % of the battery that is used. If the phone has 95% battery left and the AOD has used 16% of this part that is only 5% of the capacity, the AOD has consumed less than 1 % of the battery capacity.
So say that the phone is used very little or newly rebooted this is not bad. But if the phone has been used for several days and you have used web browser, games and other stuff there is something wrong.
