Display taking up alot of battery?

I'm on here often and see of screen shots of peoples battery info. I don't see any one as high as mine. Here are my battery stats being unplugged for 6 hours and 1m
Display 74%
Cell stand by 7%
Phone idle 5%
Android system 5%
Dolphin hd browser 4%
Voice calls 2%
Swype 2%
I haven't used it much this morning so maybe the screen is taking up the most, but it always is the highest percent. Any ideas?

Are you running CM6?

Yes, is there an issue with this also?

Been unplugged for 2h 58m
My top is Cell Standby at 25%
Bottom is Display at 6%
rooted/forever/2.1/Hydra uv stock clock
I have auto-adjust off and keep the screen fairly dim, simply because that's how I like it not to save battery.

Im not sure if it is an issue but CM6 will show high display usage, where else other ROMs would usually show cell standby higher.

High display usage is a common theme on every single phone...it's what takes up the most battery in devices. Turn down your brightness if it's getting to be too much for you. Keep in mind that charge is the percentages of the battery taken up so far. so 75% of battery if you only have 10% gone is only 7.5% of your total battery.

[Q] Is high batter % for Cell Stanby and Phone idle normal?

Been trying to improve my battery life and I found this in my battery stats:
Cell standby: 41% (7% of time without a signal)
Phone idle: 35%
Android system: 10%
com.cooliris.media: 6% (Used to be default gallery, but I unintalled it)
Dialer: 6%
Display 3%
Is it normal for cell standby and phone idle to take up so much of the battery?

Yes. Cell takes up a lot of battery, especially if you are getting a low signal

If you use an app to reduce your minimum cpu mhz, the idle should take a bit less of battery

I already underclock my CPU. from 1GHz to 900Mhz, then at 30% battery life, goes down to 768Mhz, at 10% it only goes at 368Mhz.
And when the screen is off, it only goes at 245Mhz.

Are you using an app to get those results?

i work in an area where the signal coverage is really bad and when i leave with full battery in the morning, i get home even with ~50% only. the battery is basically killed just because it keeps searching for a network

battery puzzle

Battery life under 6.0.1 seems decent enough: 10% charge remaining after 17h 52m, with the screen on for 4h 10m. The day's usage included a half hour of streaming HD video and a half hour of Skype videochat. WiFi, mobile data, Bluetooth, GPS were turned on, smartwatch connected, and social media apps were running in the background.
But I'm puzzled about the detailed battery statistics.
The screen is reported to have used 714 mAh of charge, which is reportedly 46% of the total charge used so far. Thus, the total charge so far would be 1552 mAh. And the total so far is reportedly 90% of the battery's capacity (i.e., 10% remaining).
By those numbers, the battery's total capacity is 1724 mAh. But that's only 57% of its rated capacity of 3000 mAh.
What's going on? Is the battery that worn out (despite its reasonable performance), or are the numbers being reported incorrectly?

how to increase lifespan of worn out battery?

Ok guys,
SOT was just around 5h 30 min so I suppose battery is pretty badly worn out.
Probably the phone has been used around 1.5 y and I see date of manfufacture 09/2019.
So I switched to dark mode,enabled power saving,disabled all gestures,switched to fullHD+ res and for sake of battery I'm nor charging with super fast option.
I think I won't even charge at max capacity because accubattery tells me the wear out has smallest value when I charge it at 85 %,so I suppose I will charge it to 85 %.
I will discharge battery at 15 %,never less.
I'm charging with airplane mode ON,because I'm not busy person to need phone while charging.
I can also charge the battery when the phone is OFF and I suppose that is good for battery too.
So dear friends what else I can disable in Android 11 and try to increase it's lifespan?
These are all things which came to my mind from experience.
Phoneinfo is reporting under USAGE HISTORY when I tap on it few times health of only 41 %,but don't think it's accurate.
With other software DevCheck and AccuBattery can't get battery wear level,discharge cycles info.
Now I charged it for first time after buying phone to 80 % (suggested by Accubattery) and this is what I got,dunno if it's accurate or not,but I don't believe that health is 96 %,I wish it is.

Don't discharge past 20% but 30 or 40% is a better cutoff. Charging to 70 or 80% max most times will also help. Li's prefer frequent midrange charging.
These batteries aren't that hard to change out. Just had one fail in my Note 10+. As they age that becomes more likely to happen.
Keep an eye open for rear cover bulging, replace the battery asap if this happens.
The battery sits directly on top of the display and can damage it if it swells.
Erratic fast charging and diminished capacity are also signs of a Li battery failure and with the hump there's no doubt.

oh okay,thank you.
Look at the accubattery readings,doesn't look that bad,huh?
How and when will I know that battery is for replacement?
I still can't find software which would report me wear cycles.

Accubattery... this is it's least useful feature.
Compare your SOT now to when it was new.
It's way more than a 4% drop in capacity.
In reality it's more like 60% or so! It depends of course on how much it's current draw is now and if it's about what it's usage was when new*.
It may also be the phone as it maybe incapable of actual ma measurement and only estimates it bases on battery voltage drop.
*my 10+ is getting around 10 hours SOT but with some battery hogs it could easily fall to 6 hrs SOT with a new battery.

I haven't bought new phone,just used...I wrote that SOT is around 5h and 30 min.

Great deal. You did good, the 10+ is a great phone
It still running on Pie?
The SOT runtime is very subjective depending how well optimized it is. If it's running warm* while surfing the web with screen brightness at 40%, it's not optimized and probably using more battery than it has too.
*ambient temp around 72°F but the phone is noticeably warm.

Great app for getting most of of your battery with some great performance tweaks as well. Difference is very noticeable on my device and premium is very reasonable.
Also recommend tasker. I have it set so my NFC and mobile data are automatically of when at home and automatically turned on (with WiFi off) when WiFi disconnects. Also GPS off at all times unless Google maps is open. These made all made a huge difference for me. Reckon combined they at least doubled my battery life per charge.

Question ELI5 | How do you count battery usage

im just curious. on miui adjacent to the app it shows mah. on 1% battery left it adds up to 3047mah. F3 battery is 4520 and also BBS show nearly the same app usage. So where am i losing it

Try GSam Battery from Playstore

You're losing it to measurement error and random losses
- It's hard to actually measure these things. Maybe you get 10 samples of how many mA is going out of the battery at a moment every second. So you can assume that every sample counts as that mA being delivered for 100ms, but maybe there was actually a spike in between that was missed, or the measurement itself is a spike. You will always just have a general estimate.
-Then there is also a difference between drawing 800mA and drawing 200mA. You might think that 800mA for an hour would use 800mAh, and that at 200mA you could use the phone for 4 hours and deplete the same 800mAh. In reality, the battery will be less efficient at supplying 800mA so it will be emptier after an hour of doing that compared to 4 hours of 200mA. And then there's probably some overhead too, so maybe a 90mA draw is actually also less efficient.
Compare it to a car. You get more miles per gallon driving 40 mph than 80 mph. But when you start driving 10mph the motor might be less efficient, and suddenly the power consumption of the radio and A/C will start counting a lot more, especially with how much more time it takes to get to your destination.
