Does anyone have any idea why my screen is always listed at 72% on the usage acreen? From what I have seen others are at around 40-50%.
This happens even when I have brightness lowered to 20% (and following several power cycles) so I am perplexed. Any ideas would be appreciated.
Thanks. (Edit: 72%, not 78.)

What is your screen in time?

Thanks for the quick reply. This happens from the moment I am done charging, even after the phone has been powered down. Right now I am at around 7hrs on from dead, maybe 2hrs screen time.
Funny thing is there seems to be no variance (whether I put brightness up to 100 or down to 10), which leads me to think the reading may be inaccurate.
My soft key lights do stay on all the time, unless I am in the full sun or put the phone up to a bright light, but apparently that is normal.

Just an update in case anyone else had the same issue: after about 24 hours at low brightness without a reboot, the phone finally seems to he reporting the correct brightness on the usage chart.
It's strange and I don't know what caused it to finally act normal. Just glad I don't have to consider an exchange.

Just to be clear... You meant battery, not memory. Right?
Yes, right! Battery, not memory, usage. Thanks.

Mine doesn't drop under 70%. Anyone else have this issue?

Doesn't really say anything. It just means that your display is taking up (approximately) 70% of the total power used.
You have to see it in relation to how you use your phone. If you have it just lying around with all power hungry stuff off and just turn on the display to look up the time from time to time you might get such a figure.
Hello guys.
I have the Sensation for 3 days now, and i`m dissapointed about the battery life. I`m coming from Android HD2 who in stand-by had 2-7mAh consumption.This is my first native android phone, so i don`t know what numbers Current widget should show.
I switched off bluetooth,wifi,mobile network,gps and my consumption is 168mAh which seems a bit higher.
So, if anyone could verify on his phone, because i want to know if this happens with all the phones or just mine.
Thanks is advance!
Take the results from that app with a grain of salt. Usually, what it reports is not accurate. You can only notice how your battery life is after a few charge cycles(will take a few weeks)

That's about average. I use Green Power to save some battery. I get a few more hours from using it. Also I'm using the 1900mah Anker battery.
No battery monitor correctly reports standby current yet

The brightness setting seems to have more influence on battery life than anything else in my experience. Try setting brightness to 20% or less. I tried auto initially but there appears to be some issues with the auto setting where it gets changed to 100% after using the camera, etc.

I just tried turning off auto brightness and setting the screen much less bright than auto had it set to. I then checked the mAh using Battery Monitor. It said 221 mAh. Turned auto brightness back on and it shows 136mAh, even though the screen is clearly brighter. Did this twice and auto used less mAh both times.
So, something doesn't make sense. Either Battery Monitor is nuts, brightness is not correlated with mAh the way we all think it is, or auto is somehow more efficient than a fixed setting.
where can i see how many mAh my Sensation use? is there any app?

I've actually run into that issue while my setting was at ~%20 and also when the phone starts up. Though it doesn't come up often enough for me to try anything other than manually changing the screen brightness back down.
I have been using my Sensation for a 3 months now and have noticed the idle battery usage very high and barely get through the day without touching my phone. Well that's probably my own fault for having this and that syncing and downloading all the time. And my suspicions were correct, because when I turn data and WiFi off the battery could last forever. Understandable.
What really bothers me is that when screen is on the juice just disappears. It's just 2 to 2,5 hours of screen being on (web browsing, playing games etc.) to make the battery completely dead. This is pretty much my first actual smartphone and I understand that such a big screen takes it's toll, but is that normal?
I have the AUO screen.

Sounds about right to me. Have never used my screen for two hours straight, but I'm at 36% for about an hour and thirty minutes of screen being on with an Anker battery.
Regarding the syncing, you could probably try juice defense and see if that helps you any.

Yeah, maybe I should get an extended battery. BTW my screen brightness is on auto. Wonder how those 4.7" beasts will handle usage.

Hi,
There has been a lot of talk about poor battery life,and it is mostly attributable to the kernel.
My best suggestion is to update your kernel to:
1.Faux's latest...in my sig
2.Bricked 1.41r has had good reviews...HERE
Make a nandroid backup,
wipe cache and dalvik,
flash kernel,like a ROM,
reboot.
Also, try guide from my signature.. It helped me
How much difference does it make battery wise whether you're e.g browsing the internet or playing graphically demanding games?

Today after fully charging my phone I took it off charge and i set my brightness low and after 1 hour of playing asphalt 6 I checked my battery stats and it showed that the screen has used 87% of battery whereas asphalt 6 and wifi only had drained 8% of battery. I'm using 1730mah battery and I want to find out the battery usage other people are having after playing 1 hour of game
Sent from my HTC Sensation Z710e using xda premium
If screen dont drain any battery than we could play 10hours of asphalt 6 non stop while we still have 16% of battery left. Beside I know that impossible but still I'm sure there must be a way to stop high screen battery drain

I believe the only way without buying a new battery, is to reduce the screen brightness
Its a well known fact that Our Screen need more juice and is the biggest drainer of battery.......Try keeping brightness under 30 or buy an Anker battery.
I did keep my brightness to the low because it was night time and still it showed that screen drained my battery a lot I don't know what would have happened if I kept my brightness full

Bright or not the screen (specifically the backlight) will always be the biggest power consumer on the phone. There is no way around this.

well i got an sensation too with viper rom frmo the venom team and after the update i recognize a much harder battery drain than before but all apps are the same so dont know why and no one else is experiecing something like this :S
The biggest drain on the battery is the screen and the back light for the screen. I've noticed a significant improvement by disabling auto brightness (this is controlled by the kernel and rom parameters) and just setting brightness manually.

Hi everyone,
I'm currently running CM10 on my AT&T One X. It runs great, but when I hit 6% battery, it suddenly jumps to 1% and shuts off a few seconds later. I've tried recalibrating by using the app available on Google Play, as well as letting it shut off and recharging all the way. Neither have seemed to fix the issue. My question is; are there any other ways to recalibrate the battery, or simply cause the battery indicator to display the proper percentage?
Thanks to anyone with advice!
Have you looked to see if anyone else on CM10 reporting anything similar?
In any case, the battery meter is not all that accurate in the best of conditions. I wouldn't trust the meter being below 10% to mean you have much significant battery. Really, by the time you hit 20% or so, you should be looking to charge.
Why you letting it get that low? Normally around 10% I plug in.

It's not habitual or anything. I just normally don't plug it in until I go to sleep, and sometimes it dies before that time comes.

This isn't based on facts but my 2 cents is that because the calibration of the battery isn't wiped, it's not accurate. There's no wipe battery stats in TwRP. If you ever notice the battery percentage in TWRP after flashing many ROM, it differs from the actual phone.
I wipe the batterystats.bin in data/system when full then reboot but who knows if that even works. I had my phone turn off @ 3% once so who knows but charge it as soon as it gets in the teens. Its bad for the battery if it keeps powering off when low.

You're right: that isn't based on facts.
Battery stats get reset every time you charge your phone. Manually wiping them does nothing.

This issue has been discussed in other threads. Seems to be specific To CM roms only.
Some report steep declines from 40% to zero in seconds. You seem lucky.

I wouldn't worry about it. Mine turns off anywhere from 5 to 15%. The battery percentage is just an estimate based on the software, it's not an actual indicator. As such there are tons of variables that can affect when the phone is actually out of battery.
TWRP also doesnt report battery correctly and it has nothing to do with the stats. It is taking more of an educated guess as to where it's at. Believe it has something to do with are phones.
thanks for the info.. i have experienced this issue also
Battery percentage is guessed at based on voltage. As the battery drains, voltage decreases slightly. Yes it is an educated guess. Every battery behaves slightly differently and has a unique profile or discharge curve. Some may be steeper than others at the end, but the device should learn this and adjust accordingly. An internal short in a composite battery like this would also exhibit this behavior, only exhibiting itself at certain voltage levels(dependant on location of physical short in battery) where voltage drops to 0 at that moment. I have seen this issue in defective packs where they work fine most of the time, but then zero all of a sudden. I'm not saying this is your problem, but the case design/new soft shell battery(no hard plastic shell to protect against the internal layers from being squeezed together) is wide open to physical damage from the phone being compressed.
Try a stock ROM and verify it works normally. If not, the battery is damaged.
My One X has never shut off before it reached 1%. I unlocked it 4 days after getting it in the beginning of June and have been running CR ever since and never had a steep battery decline.
