I often see people referring to battery usage as mAh. What does this actually mean and how can I view it?
Thanks
Use current widget downlaodable from market...
mAH is milli amps an hour, current widget will let you see power draw at what ever interval you set.. Enjoy

PowerTutor was reporting the Current Widget and Batteryminder as the biggest battery drainers... And after uninstalling them, my battery last longer

No, it's milli amps hour = m.A.h
milli amps an hour = m.a/h
OP: When people refer to mAh: they should be referring to the capacity of a battery, as in how much energy it holds.
mA is a measure of current, as in how much energy per time is used by the device (or is charged to the battery). Current widget is indeed the tool to measure this.
Thank you for the quick reply everybody.
I have downloaded and installed "Current Widget" and it's telling that I'm using 270mA when in standby. Is this normal? My phone has been booted for hour and it's already eaten 16% battery.
I am using Darkstone's SuperRAM Froyo. In my battery usage panel it is telling that the display is taking up 79% however it is set to 20% brightness.
Anyone help please?
Enable the logging feature in current widget, then put your phone in standby for a couple of minutes, and then check the log. 270mA is not your standby usage, current widget just hasn't had time to update yet.

as if i put it in idle, and it can last for two days.
it is 95% now and i checked with Battery indicator pro and it shows
light usage left: 34:12h
normal usage left: 15:12h
heavy usage left: 7:36h
constant usage left: 3:48h
is this so far the most power saving build? or anyone has suggestion? i have setcpu and task killer.
There is no "most powersaving" build. It always depends on various things you have done. Also I think those numbers are just an average, they don't have to be right.
When I leave my phone in standy at 100% battery it stays about 2 days in standby before it reaches under 5%. Just a tip, never let your phone running android run out of battery. I have heard this may cause corruptions of your data.img file.

Jepp... that happened to me. Not to recomend, had to reinstall from zero.
i have tried mattc leo build before and others..it does not seem to last longer as this build does as for example..when u have 100% and u disable most things task killer, setcpu and dim the display and the next day (not even 24hrs) it drop to like 30% or lower..i even install autostart and disable thouse autostart apps or background, still the same.
When i use this build same thing but just didnt do autostart things...and 100% put it idle..and next day (not even 24 hours), you will still have like roughly 80% and play around bit and next day afternoon and it still has 60% or something...
i basically try to test the phone in light use or mostly idle..
it basically the best so far i have tried (i just used 3~5 different builds)
i dont know how to check the standby ma as i saw someone said use battery status but i downloaded it and it does not provide much details but only
light usage left: 34:12h
normal usage left: 15:12h
heavy usage left: 7:36h
constant usage left: 3:48h

You have to check this with current widget. It's for free in the market. Set the intervall to 1 min. And remember: It's not an app, it's just a widget.
If you got a standby drain of < 10mA you're a happy guy
As I never tried much builds because I like mine with Sense, I have to say I don't know about the battery lifes of others, but as I heard and seen, should mattc have a very good battery life.
Watch my setup in my signature.
I've installed SetCPU and some profiles. I recommend using the conservative governor, seems the best so far. With data enabled I get a standby drain of about 5mA, so my phone lasts without any problems for 2 days in standby.
hihi may i ask what is your standby ma? <10ma?

I downloaded Circle Battery Widget the other day to have a battery widget on my lock screen (I use WidgetLocker). Immediately after putting it on display it showed "74%" which I thought was weird. Turns out it shows the correct percentage exactly all the time.
Thought Motorola designed the battery meter to only meter in 10% increments? Every other widget/app shows only 10% but this shows exactly...might have something to do with it actually measuring the battery voltage (you can see the voltage and temp of the battery in the corresponding app). Someone else download it and check it out

There was a thread about this somewhere else... the general consensus was that it works on estimations. I monitored it as the power drained and found that the stock "10%" scale changes when the circle widget goes from 5-4 (example: goes from 60% to 50% when the circle widget changes from 55% to 54%).

Well either way it's been pretty spot on thus far. My only guess was that it showed a percentage based on the Voltage (because it shows the exact voltage in the battery in the options if you poke it). It's crazy accurate...not sure why Motorola didn't incorporate the same idea into its own Battery displays...
I'd only wonder about moto's decisions when they start making sense.

Hi!
I am going to buy a Huawei U8800 soon but I am wondering about the battery time, how good is it?
Could you please post a report over your usage and how long the battery held.
Thanks!
// Sebgus
Pretty standard for smartphone.
With heavy use - from charger at morning, to charger at evening. With easier use battery will last for 36-48 hours.
And then I guess you use apps like facebook & twitter that updates all the time?
EDIT: On the homescreen I meant
I may have a faulty unit, but my battery time on my X5 is bad, almost to the point where I want to sell it.With a full charge,GPS,Bluetooth and WiFi turned off and minimal usage throughout the day I'm at 10% by 8pm.
power121212:
That doesn't sound that good! But it seems like the quality on the batteries shipped with the U8800 shift very much? Some get a decent 2 days with normal usage and some are fully charged in the morning and then almost empty at the evening.
Shouldn't warranty cover that?
I would like more reports please, want to figure out how good quality they have. Maybe can do a template:
Date on purchase:
Batterytime w normal usage:
Activities, normal usage (what did you do):
Batterytime w heavy usage:

Thanks!
I'd just like to point out that you CANNOT rely on the battery meter to give you an accurate reading for the battery capacity. If your phone drops a few % very quickly then you need to remove batterystats.bin and power cycle the device a few times. Initially when I got mine it went 'flat' quite fast telling me to plug in but when it hit 0% it then shot back up to 30%, since the remaining capacity would have been recalculated.
The battery life is good. It is a large battery for this size of device (1500mAh) the HTC Vision has a 1300mAh (more or less the same hardware). Just be smart about how you use it, don't keep over 9000 widgets on you home screens terminate apps completely, don't leave wifi/gps/3g on unneccessarily (it only takes a few seconds to reenable them in settings)
I agree to Poulsen8r .too much running appz on your phone may cause the battery empty fast.I suggest to monitor all those running appz and turn it off if unneeded.

Agree. And it greatly depends on your location as well, I mean your battery would definitely last longer if u're sitting besides a strong cell tower all day without finding, detecting and re-connecting cell towers.

Yeah, the battery is large and nice. I will try to take it easy with the widgets, even if they are tempting. Leaving wifi and gps on is just waste of battery imo, so no worries.

Make sure your phone is fully charged and plugged into pc then:
start terminal/cmd
adb shell
rm /data/system/batterystats.bin
reboot
Unplug your phone and let it discharge WITHOUT TOUCHING IT as long as possible ideally until its empty. Then charge FULLY and discharge again. Then it should be fairly accurate and consistent (no sudden drops pf 10% in 10mins).
theres an app here in xda that helps to do battery calibration:

Rooting, SetCPU and the battery calibration-app feels like a must-have!

Hi!
I installed NAND rom on HTC HD2. I have battery problems (I think).
I left it for sleep for 6 hrs. I turned of bt,mobile network wifi. He lost nearly 15% in that state. I received only one sms. I cant get battery through day. Is that normal or i have problems ? Also i would like to know is there any program to se battery wear out level like on laptops so I can know to replace it. Thanks in advance
Adition on battery stats now i have 12% 16hrs since charged 14.5 stand by 1.5 up time. Is this normal?
try controlling running operations at background. i use android assistant for this. use battery monitor widget for battery information and statistics. at sleep it should consume 2-6 ma. be sure auto sync is closed. control screen brightness, it eats battery very much. with some kernels after activating bluetooth it consumes 60 ma battery in standby until you restart. for good battery life prefer cm7 roms (i'm happy with hyperdroid

Use CurrentWidget from the Android market (free). Just put the widget on a homescreen, put the device to sleep then after a minute or two check the battery drain.
Sometimes my phone is left with 5 to 10% of battery and I plan to give it a full cycle, so
whats the best way to drain the battery quickly?
I found a few threads on xda but i can't get them through
@_Dagan_ on one thread said Ghost Radar app will do it, but
there are many apps named Ghost Radar, i don't know which one to download.
So kindly tell me how to drain my phones battery faster and safer.
Set the screen brightness and timeout to the max value
Turn on the flash light
run benchmark app

The safest thing to do is to NOT do that. Running your battery completely dead is worse on your battery, just charge it from 5 or 10%.
Lithium-Ion batteries should never cycle all the way down. In fact, with Lithium-Ion batteries, the higher the charge left the more charge cycles you will have with the battery. Nickle-Cadium batteries (Ni-Cad) are the ones from the 80's and 90's that developed a memory and cycle was NEEDED with them. There is ZERO memory effects with Lithium-Ion batteries.
For example... if you charge the phone regularly when its at 25% battery left or lower you will get roughly 250-350 charge cycles. 50% battery left and you will get 1000-1200 charges cycles and if you charge it at 75% or more you can get roughly 2000-2200 charge cycles. And obviously a charge cycle is when you charge it to full so if you charge it once a day then that is 1 charge cycle.
My battery rarely goes below 50% battery with 4-5 hours of screen on time and that's after a full day (8am-midnight) and i plug it in each night.

I have a question for you, I hope you can help me. I have samsung note 3 EU from two months, the rom is android 4.4.2 original , I use auto brightness, energy saving active, all disabled, except the 3g that is always active. I have a problem with the battery drain, because I use the phone five minute to see web page on internet and my battery drain 2% , for example if I have 100% of battery pass to 98% in 4-5 minutes. This is normal? I have to send the phone to the assistance service?
I made an hard reset but not change the time of battery drain. Help me please.

Well, a lot of things go into battery life. Surfing the web since it uses data and when on 4g or LTE data you will use a lot of battery. That said, things I do for best battery are these...
Any app you don't want or need running background data i would restrict the background data under settings-data usage then tap what is using data and you can tap restrict background data. Turn off all your syncs (use manual sync) unless you have to have them like email maybe and dont let it sync every 15 min maybe change it to once an hour or every 4 hours. I would use your internet for about an hour of surfing and see what you get after that. I probably lose about 10% battery per 45 min or so of constant web surfing on stock browser at 30-40% brightness. Also, turn off your auto brightness... it will never save you battery but use more. it will almost always be brighter then you need. Just adjust the brightness as you need it. I run mine at 20-25% brightness unless i need it higher.
hope this helps.
on GPS, turn on waze navigation
turn on wifi tethering, connect another device to it and play a 2 hour HD video on youtube
at the same time connect to a bluetooth speaker and play a song
screen brightness set to maximum
do the above 4 at the same time. should be dead in less than 2 hours

Well I can't help much with gmail since I don't use it. I looked in Gmail settings and I see no options for sync times either. I use stock email. You might not be able to change or specify that. Someone else that knows may be able to chime in.
