My battery is draining 890ma~1000ma when screen on.. even the charger cannot keep up
Now as i type, battery dropping.2% every 1min or so. Just 30mins use, battery is already at 48% .
But if screen off, the drain is like 2ma. I cant brain whats up with my phone
The battery itself could be going bad.
What do the battery stats show as the biggest user? And is there a wake lock that's keeping the phone on and spun up at full speed at all times?
Try using 'Badass Battery monitor' from the market. It would point to battery eating evilness.

My new battery dies when it has 5% left i have been reading to calibrate it. What way should I calibrate the battery software or clockwork mod???? Thanks in advance i am rooted and am using AndroidRevolutionHD. I have used the battery calibration from the market but it seems like my battery is draining in 2% intervals. Is there any other software I could use or can what is your alls recommendation

Calibrate it the old way. Let it completely die and then let it charge for 8-10 hours. Make sure the phone is off while charging. Do that twice and that should calibrate battery. Also look on the market for a battery widget that way you can find out what is draining your battery.

When I get to about 10% left, the phone suddenly says that there's 1% left, and turns off. Im on ARHD with faux 004. Tried the 005, but same problem there. The problem happens with both the Anker 1900 and EVO 3D battery, so its not the battery that's failed.
Tnx guys!

Yeah I have that issue too.. The thing is battery is not properly calibrated.. Also you can see that once you charge your device with that 1% left within 2 minutes you'll see that battery is 12-15 % charged.. Which is not possible
Also once you got 100% you'll have 100% even after 1 hour of usage.. That's how it works in my case with anker battery

You need to properly calibrate the battery. To do this go to the play store and download an app called "current widget". This is a widget that will tell you the physical mah values of your battery, in other words, how much juice you have left when your phone is not charging. Make a widget in your home screen and put the phone to charge, when its plugged in the widget will tell you how much mah of charge is needed to be 100 % full. Do not disconnect the phone when the led light turns green as it is not yet fully charged. You can see that when the light turns green that the mah values have not reached "0" So when the mah values reach to "0" or somewhere near 0 (<10), your phone is 100% charged. At this time, with the phone still plugged in go to the recovery menu or another app that can "wipe the battery stats" and reboot the phone. Your battery is now successfully calibrated and should fix your battery % issues.
Yeah, same as me then. But the battery is calibrated as oneonesix says, so its a bit wierd.

My phone was reduced from 100 to 82 in just around 6 hours. I had data/wifi turned off as well. Is anyone else experiencing this?

Nope. With data/wifi turned on (data auto-off since Wifi is active), I lose at most 2% overnight. With airplane mode on OR data/wifi off, you should be seeing practically 0% loss.
Check your battery usage and see what's eating up the battery. Sounds like an rogue app/process that's wasting cycles or is out of control.
One of the best things about this phone is its standby life, as it seems to sip battery juice very lightly.
My battery was still 100% after I woke up today.
Nevertheless it dropped very quickly after using the phone, about 11% in 10-15 min but I assume that's completely normal after 8 hours standby.
I have a live wallpaper but it shouldn't work when is screen off. I also have setcpu set so that is practically doing nothing when the screen is off. The live wallpaper cost only 2% of my battery but standby showed 20%. I have no idea why it uses much in standby...

That means that of the whatever % battery (out of 100%) that you've used, 20% of that drain was due to standby. That's not necessarily bad. So if you have 50% charge left, then it means that (50% x .2)% of your drain was from standby. My cell standby has currently used 23% of my current drain percentage. Since your phone is often left in the sleep/not-active state, then a large % of battery drain happens in standby.
Battery usage on Android is frequently misunderstood. And keep in mind that the 2% from the LWP you used is because it's only displayed when you're on the home screen. Otherwise, it remains dormant/paused.
that's strange that you are having that much usage in standby.. i have been getting a solid day and a half out of my battery and it doesnt really use any battery in standby.. there has to be an app of some sort that is sucking the battery or still running.. i always at bedtime though clear the cache thru storage in the settings menu and end all tasks in the task manager and close all the windows/programs with the far right virtual button on the bottom of the screen.. I am a bit OCD but heck if its working why stop..lol
Area with poor cell reception? If you were in plane mode it is an app for sure.

My battery stayed the same overnight. That is with a x2 battery saver which switches off data when the phone is not used and only allows it as special intervals. I have set at 10mins intervals though which is not a huge saver.
I'm doing a test from yesterday to see how long the phone will last with my use. So far from last night im at 39% and when I first turned the phone on it was at 47% from yesterday.

I would have to agree with everyone else. I only experience 1% loss at most times overnight. Best standby battery life i've ever gotten on a HTC phone.
I actually have full bars at home so I don't think that's why. Maybe it's because it's a new battery so I'll try charging it a couple more cycles.
Lost 8% tonight (86/78). Saw this morning that the signal was not perfect. But wifi went off during the night. That should not happen. Maybe my custom rom is switching off wifi on sleep...

It's either a faulty battery or a rogue app. Shouldn't happen to a new battery either.

Use better battery stats to diagnose rogue apps.

Right.
Battery lasted up to 2:30pm being off the plug from 7 am the previous morning. So a total of 31hours.
That is with tapatalk, a bit of web browsing, a bit of WiFi and google store updating, 2 short phone calls.
The app. 2x was running on mild battery saving,mainly by cutting the data periodically when the phone is idling.
I must say that this is really good and the phone took quite a while to go from 15% to 4% after which it switched off before I noticed it again.

I'm reading some guides and posts about battery calibration...
I'm trying to do it with battery calibration apk, but I can't understand when battery is really full even if I use current widget (it stucks at 10mv, it does not come down to 0).
how do you calibrate?
Do wipe status as long as u riched this value as a maximum. .. restart. .. let it with out charging till it gets to 1% then charge it again till 100% do that a couple of times ur battery should be calibrated for good; )

To know when its fully charged you need to be watching ma not mv. As ma is the flow of electricity that your battery is currently receiving, as long as your phone is on it will not hit 0 as your phone will still be consuming battery so it will always sit between 10 and 20ma when fully charged. As long as your happy its sat around that mark for a few minutes then its charged. But best way to calibrate in my opinion, is to just discharge to 5% and charge overnight. Wiping battery stats does nothing as your phone creates a new battery stats file on its own after every full charge and battery stats.bin only contains information of what's been using your battery like in the settings menu. This has been confirmed on xda portal by a Google software engineer.
Your phone is clever enough to figure out what charge your battery has by measuring amps and volts once its been discharged and charged a couple times as by then it will have a established the minimum and maximum mv your battery can hold and battery stats file does not hold this information.

Hi. I'm using htc sensation xe with viperS 1.4.1 rom. normally it took 2.5 hours to charge from 10-20% to 100%. but lately, (for about a month) it takes up to 4 or 5 hours to completely charge it. I bought a new battery and charger, but i can't feel any difference. i have some battery drain problems too, but it seems almost everyone has that! is there anything i can try? thanks.
For the battery drain problems you can get Better Battery Stats. This app will let you know if you are getting any Wake locks. Wake locks can be the biggest battery drain. If you are getting wake locks that app will help identify which app is causing the issue and you can delete it! You can get better battery stats here on xda, or even in the market. This will help your battery drain issue. About the charger, my charger takes around 4 to 5 hours to charge fully also. Never thought it was a issue.... I'm thinking it's normal, however I could be wrong. Best wishes.
