I'm on an EVO 4g (but I don't think this is phone-specific) and according to the battery monitor widget app (and confirmed by touching the back of my phone), my battery gets pretty warm when the % remaining gets lower. In fact, at 2% battery remaining (a little under 3500 mv reading), the battery temp reads over 40 degrees C.
Is this normal or is this a sign I should exercise my warranty and get a new battery?
Oh and yes its a stock battery.

When in standbye overnights my phone goes from 60-70% to totally flat, I use battery monitor and I notice the phone use -100 till -200 Ma while I don't have any sync going on?
Somebod else with monitor app please give me our numbers
I have noticed tha cpu works (without any app loaded) about 35% -45% with no reason...that eats battery !!! any other have noticed that ?
I can make a video to proove that !!! Maybe with 2.3 the resoults will be better
I will give you my experiments:
First night(GMT+3 timing):
from (2-3)am: Wireless on, battery percentage still 19%
from (3am-4pm) wireless of, battery percentage is still 19% !!
Second night:
from (9am-5pm) battery percentage was 99%, when I wake up there were two missed calls and the battery percentage was 90% !!
Third night(Last night):
from (9am-6pm) battery percentage was 70%, when I wake up there were one message and the battery percentage was still 70% !!
* It is not nights, these days I actually sleep in the morning, and the timing doesn't mean I sleep all that, but before going to sleep I use my laptob.
I had the same issue in the first few days. I dont know if you installed some apps, but after I deactivated "green power" (for saving battery life) the battery lasts very long in standby mode.
so deinstall apps which say they would save battery and close all apps (browser etc.) before you sleep.
I dont know if the app was responsible for that or just the battery which needs a few days to generate 100% power.
Had mine for 2 weeks now, battery lasts 10 hours from 100% to dead, same as my Desire did.

Battery monitoring and optimizing apps did suck most of the juice out of my battery. Deleted all,my battery easily makes 12 hours now

I don't have any numbers but my phone goes from 100% to around 93% to 95% overnight depending on how many emails I receive while it's in standby.
About the same as my old Galaxy S.

That sounds great!
My Galaxy S2 would lose 30-40% overnight with a few emails...
I can't wait till I get my O3D.
Have a sensation 4G yrsterday i exchanged the stock 1540 mah battery with the xe 1730 mah battery
Waited for the battety to drain completely then from cwm i deleted the battery stats bin
Left the phone overnight to charge
At 100% cutrent widget is reading 4206 mv
After unpluging from power by 15 min battery reads 100% still but 4039 ma
Pluged it back to power battery jumped to 4150 ma instantely
Is that normal ?

Current widget will not measure the ma correctly on the sensation. You will need to use battery monitor widget and set sensation in the settings. As far as i know battery monitor widget is the only one that will measure the ma correctly. I thought my phone had gone mad as well when i was using current widget until i found out the above info. hope this helps. There is a forum on xda for battery monitor widget somewhere. It's free on the market
well i tried: battery status, elixir and current widget the 3 give the same result, anyhow am trying battery monitor to check
but usually is that a normal behavior ?

could explain what ur are observing
Hey, (first Post )
I noticed that too (got a 1900 Anker). I Think, when you plug in the charger, Current Widget shows you how much V or A the battery gets from the charger. When disconnect the charger the widget shows you how much is left.. Just thinking

yup thx, so basicaly buy a new battery (Mugen 3600mah) or bump charge the batt and screw it in 3 month i would prefer going with the second option since i change my phones very often
the problem is, even with a 1730 mah batt. am not able to play for longer than 3 hours on the phone :'( any advise ?
I am waiting for the OTA update before I root my HOX but I am still trying to calibrate the battery now. I disabled fastboot and I'm running JuiceDefender Ultimate.
When the battery reads at below 5% the voltage is around 3570mV. At 100% I'm reading a voltage of around 4185mV. Is this normal? What sort of min and max voltage readings should I be seeing?
I'm getting approx 12hrs (3:45 hrs screen time) before charging (that's with running Shadow Galaxy live wallpaper, and watching a 2hr movie on MX Video Player)
Thanks in advance.
The phone uses less battery because its turned down or off features such as syncing also with li-poly batteries as they drain their voltages dies down with it. Normally is a Mv in difference. Like with an electric car or RC car when the battery is lower than 5% they too slow down. The amperage pretty much goes out the window.
But for the phone HTC has a pretty insane battery management system, its normal. At 15& the iPhone mv would dropped about a whole volt as well.

I am using p500 from one and half years and i use it heavily so i have to charge it every day. Now i feel that the battery has done his job
And now i am getting a poor battery life
Sent from my LG-P500 using xda app-developers app
> how poor is it? about how many hours on normal usage? I use mine heavily on one day and it last 8-9hrs
I'm using my phone since 19 months and battery is fine heavy usage gets me 8-10 hrs battery while moderate gets about 24Hr and simple usage(just for call and msg) gets me more than 50hrs..
A Lithium-ion battery has normally 400-1200 charging cycles (Ref. Wiki).
Couple of things that shorten life span of a battery:
1) Complete discharging, it is recommended not to go below 20%
2) High temperature which implies that if you OC too much your device will heat up and battery life shortened
3) If you consume 50% of your device battery on day 1, recharge to 100% at night, and do the same thing on day 2, then you would have just finished up one charge cycle of its battery life. Constantly recharging a lithium ion battery does not shorten the battery life more than normal usage would. Hence constantly recharging a lithium ion battery does not shorten the battery life more than normal usage would. Avoid letting it sit on empty for too long; instead, keep it charged-up if you can. (REF.)
My battery behaves in a funny way. With moderate use it dissipates very fast. and then if I keep screen off for more than 10 mins then my battery starts regenerating automatically(5-7%)
I noticed a few times, with some of the phones or devices I used to own, that if you, for example, after charging the phone, let's say play a graphics intensive 3D game for 15 minutes, the battery meter will drop quite a lot(e.g. 15%). But if you leave it on stand-by immediately, you will notice that after some time, the battery meter will indicate with 3-5-7% more than before.
My battery life is under 2 hours in 3g continues downloading!

I think it's "normal" to charge it every day!! if you use it!! i charge it at least one time a day..
Lithium battery's do last a long time but they do loose there charge and become weak. After a year and a half I would defiantly consider buying a new battery. I wouldn't recommend the cheap $3.00 battery's but I would look on eBay or amazon and find a stock o.e.m battery. Brand battery's are more expensive but last probably 3-5 times longer then cheap battery's. I've read and heard that lithium battery's are not suppose to get hot but they can get warm, if the battery gets hot then it can destroy the battery and won't hold a charge as long as it should.
It also depends on what ROM you are running and what applications you are running, all that can add up and drain your battery fast. I would change a battery on a phone about 5-7 months or maybe even up to a year. Depends on your budget and what you can afford. hope this helps

Which should be max. battery voltage ?
I have never seen voltage greater than 4.170 mV at 100%, according to Battery Monitor Widget.
My Desire HD instead, reaches 4.201 mV at 100%.
Is this normal ? if not, what should be done ?

Volts are not overly important. It's the mAh that matters. My phone's battery has gone from 3,600mV at 70% to 3,755mV now at 37% (and rose to 3,759 and dropped to 3,756 while I was typing this). My old BlackBerry Torch 9810 used to do the same, my Wildfire S before that. As long as the Elvison battery widget (get it if you don't have it) tells you that your battery is in good health, then you have nothing to worry about.

Thanks for your answer.
I agree, it' s like this during operation.
My problem is the max. voltage when fully charged, which is low compared to the max. voltage of my Desire HD.
