Great initiative. Just need more people to help report their battery life, as there seem to be quite some difference among some peeps.
Yea I know, I need to find some other tests, Any suggestions?
Not a suggestion, but a question : When you go to the *#*#4636#*#* menu, what is your battery voltage ?
Many report 4200 mV after 2.2 update, but I only get 3890. I know it's not much, but still...

Has by any chance anyone made such test under Eclair?
Btw I've noticed that if you use task killer you can save battery. Apparently there are some apps that even when closed keep eating battery. But I really have no proof of it (and have no time to conduct tests). Maybe someone can help me?
And I also suspect that Chrome to Phone eats battery if you don't press "disconnect" even when you don't have any Internet connection enabled. But that's another thing I can't prove.
brief tests - unconclusive, eh
I never thought that battery percentage is accurate enough to perform these kind of test, also didn't have much time to do it (so basically % never changed in 15 minutes timespans). Anyway:
* started at 21%
- Everything off (screen too)
- gmail push on
- good (3-4 bars) mobile connection on 3G
- no 3G data connection
- Wifi on - sleep policy -> always on
- Wifi router is about 1m far away from phone
15 minutes later
= still 21%
next --------
* started at 20%
- same as before but
- wifi off
- 3G data connection on - mobile data connection NOT always on
15 minutes later (19.43)
= still 20%
next --------
* started at 19%
- same as before but
- 3G data connection on - mobile data connection always on
- gmail push received a short email while testing
- hotmail checked mail as scheduled and downloaded 6 short emails
15 minutes later
= still 19%
Tests were started as soon as % showed the reported number.
By night, on airplane mode, it loses about 2% in 8 hours.
Can't really complain. By the way I'm still searching for a tool like WinMo BatLog. Anybody knows if it's feasable on android ?

I've been searching the market for a while but I couldn't find a tool that shows the power drain in Amps
Brightness
Airplane mode - Completely white screen
* Full brightness:
started at 17%
after 2 minutes = 16%
(brief pause to check, then back on white screen)
after 1 more minute = still 16%
(brief pause to check)
after 1 more minute = 15%
(brief pause to check)
after 1 more minute = 15%
Lost about 2.5% in 5 minutes
* Minimum brightness:
started at 13% (didn't wait for full step, probably was already close to 12%)
after 2 minutes = 12%
(brief pause to check, then back on white screen)
after 1 more minute = still 12%
(brief pause to check)
after 1 more minute = still 12%
(brief pause to check)
after 1 more minute = 11%
Lost about 1.5% in 5 minutes
(kept going with low brightness)
after two more minutes = still 11%
after one more minute = still 11%
after one more minute = still 11%
after one more minute = still 11%
Apparently lost less than 1% in 5 minutes
Probably the % is not very accurate here anyway, or maybe at the beginning of low brightness test was still hot from the previous high brightness one.
after one more minute = 10%
time to plug it in, I'd say...

I've seen somewhere someone (eh) reporting that in /proc/somewhere there is a setting that can be read to do it. That is where my knowledge stops.

I have one battery at 3742 mV, however it's at 13% and charging.
The other battery, which is almost full and not charging, shows 4153 mV.
Don't know if it's affected by charging state.

Yep, the more juice you put in the battery the higher the voltage. So a more fully charged battery will have a higher voltage than a lower charged battery.
It goes from like 3.3v to 4.2v.

Erm, yes I've explained myself not very well... I meant that I didn't know if the fact that one was charging and the other not could impact the reading. I wanted to provide the approximate range of usage, since, if I'm not mistaken, the phone turns off when it reads 3.3v ?
EDIT: also on the same note, I think if I remember correctly, I've read that the % read is sometimes 'skewed' depending on how full the battery is. Like 1% battery at 100% lasts (for example) longer than at 50%. Am I awfully mistaken ?
Yeah, shutdown is usually around 3.2 or 3.3. It depends on the manufacturer. I think the batteries get damaged below 3.0v. Protection usually kicks in around 2.7v - 3.0v.
Not 100% sure, because I always mix up LiPo's and Li-Ion batteries
While charging the voltage will be a bit higher, and when you unplug it will go down a little bit.

Yeah indeed. The voltage drops much faster when 100% charged than 60%-70%. Also the reason why there seem to be so many issues with the wrong percentages shown .

Screen is set to the lowest setting using the powerbar, Also the screen was off at the time of doing the test, i.e if it was in your pocket.
During the screen test with the image, it was set to as bright as the power bar will allow

Right, so it's pointless to compare battery drain % at full level and at 1/4, for example. I've also read somewhere that battery temperature influences the reading, as well as reducing the efficiency of the battery itself.

If you really want ill get back and do it with the *#*#4636#*#* and give you 4 digit number from there
Wifi streaming + screen on
Tested music streaming with xiia
* first run with WiFi
- most stuff off, same as previous tests
- music channel was accujazz
- music through the speaker, half volume
- WiFi on
- Airplane mode on
- Screen on (forgot the timeout off)
Battery went from 92% to 88% in 15 minutes (4%)
* second run with 3G
- same as above
- no airplane mode
- 3G in place of WiFi
Battery went from 68% to 62% in 15 minutes (6%)
I've repeated the test and still it seemed that 3G consumed a bit more battery than WiFi (5% vs 4%), but this might be also due to the fact that the first test had no mobile connection on.

Do I feel stupid now not having ever used that as a reference for testing
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.
I charged my HTC ONE X to 100%, took it out of the charger and I have now been 1h 37m 46s on battery, and it ALREADY has drained to 70% !!!
what my phone uses or so it says :
screen 78%
cell standby 6%
android OS 5%
android system 4%
phone idle 4%
whatsapp 3%
what does it mean 78% screen? that my screen is the big killer for my drain? because that would make non sense since I have not had it on that much..and still.....30% in 1.3hours? that's just insanely bad!
stock rom from Holland btw...didn't change a single thing to my phone since I do not know how....
any input on why it drains so rapidly?
thanks!
I would post a screenshot but I don't have ''root'' access'' or something lol sorry!

firstly you can take a screenshot by pressing power button and home button at

how old is the phone?
you are ok bro. for me it drained 17% with 15 minutes screen on time.
this is one big lol.
i am struggling to get 7 hours battery life
If you don't mind the effects on warranty, there are some system mods things that can be done to improve battery life...
Otherwise try turning off extra wireless services, and lowering the brightness on your screen.
I was getting 8-9 hours outa my battery, since rooted and flashed leedroid's rom and I got 26 hours with 30% to go....
what a difference.....
Basically in android, especially LCD screens, you can expect under 3 hours of continual screen use in daily activities. Often way under.
I've gone through a Motorola Milestone, Samsung Galaxy S and Nexus S, HTC Sensation and now One X. None of them broke the three hour mark for screen on time.
Standby and other use, sure, you can push a day or so but the screen is the major killer. Even with 1900mAh after-market batteries for the Sensation I was just about pushing 2.x hours. Screen usually on auto, but often inside buildings.
Counter to what may seem obvious is that if you have WiFi available - use it. It uses less power than the data connection on cellular networks and can improve standby time by a fair bit. Assuming you use push notifications and the like.

is rooting hard? i searched it on the internet but the only thing i found was some half-assed english site trying to explain what to do...couldn't follow it, and also it didn't work :/
I don't know all the terms etc they use so that makes it quite a fair bit harder for me!
Two Questions:
- What are your Brightness settings?
(Settings - Display & gestures - Brightness)
- Do you have Wifi/3G constantly on?
(Settings - Wireless & networks: is Wi-Fi and/or Mobile network: ON?)
How to improve Battery drain:
- Go to: Settings - Display & gestures - Brightness:
and untick: Automatic brightness
with your finger slide the brightness level to much lower than it is now (I have it at only 1/4)
confirm with: OK
- Whenever you do not need to be online (internet), make sure to switch off Wi-Fi and Mobile network
- Switch off notifications for e.g. Facebook, Twitter, Email (you need to open each app and in the Menu have to untick notifications)
From personal experience, I can tell you that having internet on constantly aka WhatsApp sending notifications for each chat message, Facebook and Email sending notifications, ... costs you a lot of battery
Brightness at full level also drains battery badly.
- Following above-mentioned tips, you will get a standby time on the HTC One X of up to 2 full days.
Hope I could help a bit.

You need to get on leedroid Currently on 71% battery also, but slight difference in how i got there:
16hrs standby
half hour screen on (auto brightness)
5 mins calls,
3g/wifi/locations always on.
Very light usage day for me, but it's very different results to yours
M.
edited for clarity/typos
who would you have your phone on standby for 16hours....I used it more than half an hour a day (half hour screen on as you said) so that says nothing for me lol
and my screen has low brightness but that doesn't really seem to effect it THAT much, but yesn i do have 3d on constantly aswel as fb whatsapp etc...but I do need to be in contact with people so I guess there nothing to fix :/ except maybe a ligh rom but i have no idea how that works haha, might search youtube
I have the same problem but i'm actually using the phone.
As a heavy user (and i mean heavy user) i've yet to get more than 3 hours on screen time with this. once i used it for only 2hours 20 mins and the battery was dead. I'm rooted running leedroid and the battery life is very bad for onscreen time.
Anyone else getting these figures.
hi guys..
i am on stock rom updated to latest but having problems with my battery
take a look at the screenshot. i currently have 30% battery.
as you can see from almost 11 hours of my latest charge 9hours and 20 mins
my phone was at deep sleep.(only 1hour and 40 mins of light usage)
when its locked it shows excelent battery (1% per hour) but after an hour passes and even if i just unlock it and browse a bit my phone ,i lose 5-6% .
my phone is 4days old only.
maybe the problem is just temporary?
thnx in advance for any help.
I'm using an App called 'Screen Adjuster', in which you can set the screen brightness (say 50%), and then auto adjust brightness within the selected range (50% range).
You can adjust the brightness anytime, I found it is very handy because the original auto brightness is simply too bright.
One drawback is that you can click to install 3rd party apk with this App running, don't know why, but just for your reference.
This is what i get.
With surfing a little bit gaming and chatting.
Guys i need your advice on what to do. I've checked a few battery test reviews on the s3 online and they post screenshots showing (example) 3hr 46min screen on time and the % of the battery it used was 34%. My phone right now has had 52min of screen on time and has used 38%. I have a serious battery drain issue with the screen. What should i do?
Turn down your brightness. Turn off Auto. Darker wallpapers. And not trying to be smart or funny here, but turn your screen off.
I listen to music all day long and don't have the screen on that whole time. Sure I am on XDA, browser, MLB At-Bat and a few others that I need the screen for, but I'd say that the majority of my day the screen is off.

You do realize those numbers change right? That doesn't mean your screen is using more battery than it should. It means that out of the battery you have used, the screen has accounted for that percentage. The screen will be the biggest power draw on the device if you are actively using it anyways.
turn ur brightness down instead of setting it to auto
I've a brand new Xiaomi Mi 10T Lite, but since a few days I notice that it seems that the battery is draining fast.
So I've done a test: I've charged my phone to 100% and used it until it turned off due to too low battery and it lasted 23 hours and 3 minutes.
But I doubt if this is normal and I'm kinda worried about it.
I've bluetooth off, and wifi is always on except when I go outside and then I use mobile data.
I use my phone for surfing, using social media, chatting, gaming, making nice pics and more.
So is the battery life normal or is this a serious problem?
is 23hr bad ? I feel like my one is always above 80% as it charges that fast I don't seem to notice the battery being low

I dunno
I haven't mentioned the standby time and the active time in the topic, and I cannot find that data anymore so that means I have to do the test again
I would advise to install AccuBattery app, fully charge the phone and look at screen off and screen on power consumption at the end of the day.
These numbers are "normal":
Screen off - no activity (over night or phone just laying down for a few hours): 0.2-0.3%/h
Screen off - the usual daily activity (moving around with the phone in the pocket, Whatsapp for web active, Google location tracking active etc.): up to 1.3%/h
Screen on - about 7-9%/h
I'll do another test on Friday as I said.
I'll charge the phone to 100% and use it until the phone turns itself off due to low battery and look at the active time then.
I'll post the results here if the test is done.
What were the results?

My phone is pretty new and I am using it more frequently these days. This leads to similar battery times like you describe them.
I did not do the exact same discharging like you did, but imo battery drains mainly during screen-on time. Over night it is quite stable and only slowly discharging.
Maybe power consumption is dominated by the LED screen? This might be the reason why Xiaomi has such an aggressive screen dimming implemented...
I think what _mysiak_ is describing above, is pretty accurate and explains what you are observing.

Unless your trying to calibrate the battery that's really stressful to the battery to use it like that.
Puts a lot of wear on it... fast.

I'm now trying to keep my battery level between 90% and 40% or 30%.
