Something weird happened today.

I had just calibrated my Sensation yesterday afternoon around 19:00-20:00. Went to bed around 06:00 today (don't ask :p) with ~50% remaining and with little usage, probably normal for a freshly calibrated device.

Woke up an hour ago (~16:00) and my Sensation was dead. Looking at the BMW logs, my device kept a steady drain from 13:55 to 14:30 until it shut down...

Here's the log from BMW:

2011/12/31|14:34:24|-190mA|0%|3269mV|25.2ºC|0|0

(for Sensation you never get -2-10mAh, -30-40 is as good as it gets due to battery driver)

Please notice the "2|0" after the log in 14:10:33, 14:25:33 and 14:30:33... does this mean the device was completely on? What does those two numbers mean anyway?

BetterBatteryStats shows no abnormal wake lock, I had no alarms at that time, short of someone just opening the phone and using it I can't explain both drain and numbers.

Could this just be normal after a fresh calibration and should I just wait a few more cycles?

Any ideas?

Happy New Year all :D

Thanks man, gonna give this a close read and give it a go! My battery cannot get much worse thats for certain!

it doesn't really matter mate, the main point is delete battery.stats bin, and you can do it whatever you want but following the op statements..
[Desire HD General] ghilliek9:
My experience

WOW!! This freaking works! Here are some stats...

Galaxy Nexus Verizon

All sync is on - only one gmail account

Brightness on Auto

4G on

Auto rotate on

As you can see, the phone has been off of the charger for 30 hours with 12% battery left!!!!!!! This SS was taken at about 720pm...I'm writing this at approx 920pm and have about 5% left. Normal use on it....I have surfed the web a bunch of times, made a bunch of calls, checked my emails, texted many friends and even played a game or two (nothing too long). In the past, on this kind of use, I'd never be able to make it through the night - yet alone through the following day!

I have followed the instructions here. One thing that I have learned (as it was not perfectly smooth right from the beginning) is that you have to start with a great rom and great kernel! Without that, not going to happen. You'll improve, but won't perfect it. For those of you who are wondering, I'm using the Android Open Kang Project X1 ROM with the franco.Kernel | 4.0.3 Nightly 7.1. (They both have updated the ROM and Kernel with newer editions - I might not even flash for a while since I do not want to have to format/clear anything after all this work) I have it under-volted also.

Thanks memnoc for all your help! This is amazing!
[Desire HD General] MacSeoin:
tried this guide and my phone has been on charge for 15hrs and I'm only on 25%!!!

Just wondering if this is normal after deleting the battery stats???

my battery was in working order before this!

Thanks in advance

Also my battery seems to charge faster if I use my phone whilst on charge. It boosted 3% whilst posting this!!!???!!!

Hello Mates,

seems like for some time now i can not find a solution to this problem.

for some time now i have some problem with my battery drain. everithing i do seem not to be good. i was able to get 2 days with my normal usage, now i can not get even 1 full day.

i don't know what the problem should be.

i have attached some screen captures from batt usage and current widget.

before blame me i can say that i tried everything is written in here: ( inculding fastboot tool), differnt radios, diffrent roms, etc.

the only way i can get some slow drainange is turn off completly data connection.

i just can not get it.

thanks a lot

[Desire HD General] ozaghloul:
Give this a try: Switch off the phone, pull out the battery, put it back in, then charge the phone while it is off for a couple of hours. Also if you are rooted you might wanna try to delete the battery stats from recovery before booting into your rom.

-- yea I was gonna say prob need a new data cable or charger. I was charging 15hrs and achieving only about 40% charge... Took to provider shop, tested phone on new cable

to see if it were a device hardware issue....bought a new charger, all good now ;-)

---------- Post added at 05:40 PM ---------- Previous post was at 05:23 PM ----------

--Also, try an app from the market called 'Battery XL'

Has several features including turning all or specified data connections off on standby and back on at screen on, switching on/off at a set interval for autosync purposes while in standby...also has a whitelist for apps u want to allow to connect regardless. Another setting to set the data transfer to continue until slowing to a specified amount per seconds..also an optional nightmode u can set for switching all data and radio completely off during sleeping hrs...

There are several other features also.

I havent reinstalled this app since reflashing, so I'm not sure if it consumes a lot of battery power in itself....but its still a beta version, and worth checking out in addition to what's outlined in this thread.
[Desire HD General] Shane2:
I recently installed the official Facebook app and noticed that seemed to increase my battery usage to skyrocket, in general terms I find applications that use background data and run as services to download notifications, emails ETC cause battery usage to increase, but the official Facebook app just seems to be really bad for it for some reason. Part of the problem with apps that cause battery drain is that it can be a bit hard to specifically pinpoint what is causing the issue.
[Desire HD General] suxelexus:
--Plugged in my phone until fully charged to 0mA, although, at which point I miss understood, and rebooted. After reboot I topped up the battery to 0mA, then calibrated and rebooted...did I screw up the calibration with the premature reboot???

Is there a drain considered unreasonable when running an app while not in standby? I can drain my battery very quickly browsing in wifi. And my camera will kill a full charge in about an hr or so of constant use....a game, well I just stay plugged in, otherwise may get 30-45 mins if lucky. Just want to know if that's normal?
[Desire HD General] Pointlol:
Do you have USB-debugging enabled in the development settings? That's one the first things which fixed my DHD's battery drain a while ago.

This reading tells us very little.

I recommend you use the following programs: Battery monitor widget and Better battery stats.

Use an interval of 5 or 10 mins, not 1 hour.

Remember this is about battery drain in standby only.
[Desire HD General] akpe:
Well I have problems with calibration on the HTC Sensation.

Since the battery driver is screwed up by HTC, it rarely, almost never shows +0mA. Even after 2+ hours on the charger it goes down to +5mA/+1mA, then starts draining again, then starts from +120mA until +5mA/+1mA again.

Something like this (if I'm lucky)

+7mA
+7mA
+7mA
+5mA
+5mA
+5mA
-210mA
-198mA
-150mA
-110A
+205mA
+190mA
+85mA
+80mA
+60mA
+35mA
+20mA
+17mA
+12mA
+9mA
+7mA
+5mA
+5mA
+3mA
+1mA
-190mA
-150mA
-1205mA
+186mA

etc...

Any idea how can I calibrate over this issue? Should I just wait for BMW to show -xxxmA and calibrate at that moment? :/
[Desire HD General] X46X:
Hi guys. What do you mean about this?

[Desire HD General] Black1982:
Just wait till it reads a very low value like +5 +3. Then wipe your battery stats. Let it drain untill the phone turns of by itself. Charge to full again. done

---------- Post added at 01:49 PM ---------- Previous post was at 01:45 PM ----------

I would use BatteryCallibration app to wipe battery stats. Much easier. And I would not turn the phone on again without charging it when the battery is empty. It could be bad for the battery.
[Desire HD General] X46X:
I do it from ES file explorer.. It could be bad for the oldies battery, but newest battery never gone to full empty - phone not allow that..
[Desire HD General] TaFFy4BoBo:
Is this behaviour normal? I can see that dialer eats a lot of battery, and I did not make phone calls at all, 5-10 minutes tops. How can I stop it from running?
[Desire HD General] Black1982:
Maybe it will help to disable pocket mode, flip to speaker and other option under settings/sound. Install betterbatterystats. (see my sig) This gives better info on what is keeping your phone awake. The thread also offers great support.

---------- Post added at 02:50 PM ---------- Previous post was at 02:45 PM ----------

A file explorer is also possible, but from my view batteryCalibration App is easier AND safer (esp. for noobs)

About the battery not going to total empty, true but I'm not sure if this protection keeps working if you keep trying to boot up with an empty battery, also I think it is not necessary.
[Desire HD General] X46X:
You think that flip to speaker drain battery?
[Desire HD General] TaFFy4BoBo:
Ok, I installed betterybatterystats, what should i post here? Screenshots or does the app save logs like currentwiget?
[Desire HD General] Black1982:
There is an option for making a log file. You can post it here, but t would be better to post in the BBS thread. Also post the log from currentwidget and screenshots from settings/about phone/battery/battery usage. Including the screen that you can see when you press on the graph.
[Desire HD General] (^.^):
Hi mates, I have issue using this method.. I calibrated the battery stat file by using battery calibration app and used it until the phone turned off , then I turned it on and charged it from 1% to 100%.

The issue is, I noticed my battery suddenly charged up to 100% while it was at 82%, it skipped 83%~99%.. Anyone has this kind of issue??

Thanks.
[Desire HD General] akpe:
I had this issue on my Desire HD, it skipped from ~88% to 100% while charging. Can't say if it's normal or not, but I remember other perople here experiencing it as well, although in smaller "skips", like from 90% to 100%.

cant get under 270ma with wifi connected... is that normal??
[Desire HD General] sigurd_LU:
Definitely not. I'd recommend you make a full wipe and set up your configuration from scratch. Restore you apps step by step to be able to tell which app is the culprit. Also don't restore any system settings/apps.

Also: what radio and RIL are you using, on which rom?
[Desire HD General] angusc:
What ROM are you each using? Its not much help staying put battery life unless you also state which ROM your using. To improve battery life here are Few tips to change your settings:

1) in wifi settings press menu and advanced, them set wifi sleep policy to either after 15 mins or not when plugged in to charger. This switches if wifi after15 mins of screen off.

2) change your sync settings to "wifi only" then only turn on your data connection When needed.

3) set your phone to only manually sync data.

4) in power/power mode settings change from "performance" to lower setting.

5) don't use a live wall paper.

6) set your screen brightness to lower that the standard "auto" setting or if your custom ROM allows it then using RCTeam tweaks set it to auto with lower our lowest setting.

7) turn of GPS, BT, and only enable when required.

Below us a typical heavy days use of my phone, note the time that the display is on and phone is awake, I'm a heavy wifi and tapatalk user so this 13+ hours is pretty good. If i leave my phone in my pocket all day then i would achieve more than 24-36 hours on a single charge.

My display is still pretty high, and how comes I have awake time which is double that of screen on time? Any ideas on how to bring down awake time? I assume that is the time when it isn't in deep sleep and it making the little spikes in my mAh usage.

To find out which (if any apps) is keeping your phone awake on standby you can use this tool :)
[Desire HD General] danton11:
@Nightst

Try and flash another Rom with the same apps and setup and see if it's a Rom problem...

Also your battery is not fully charged at 4.1xxvolts even if it says 100%! It's should be 4.204v.

Even though you calibrated it wasn't enough.

Charge to 0mA reboot,

charge again till 0mA reboot, charge till 0mA.

Turn phone off,

unplug then plug in charger

charge till green light,

unplug charger leave for 30 secs, plug in charger till green light.

Repeat 20 times or as long as you can!

Switch phone on to check mA if 0mA reboot to check if it stays below 4/5 mA.

Check voltage level. Should be 4.2xxV.

This is the only way to fully charge battery.

Tried and tested on many different phones...
[Desire HD General] NiGHTsC:
@danton11

I'll test another ROM ASAP, didn't expect that at all.

Well, I let it charge for 12hours+, but I guess it's just because the problems I have

will try what you say after I install new ROM and hope I can have a good news soon :D

Thank you.
[Desire HD General] danton11:
Let us know how you get on..
[Desire HD General] NiGHTsC:
Now with CoreDroid_MULTI_DEVICE_Sense_3.5_26.1.12_RV

and it seems the same...

I just can't get it to 0mA/4.2V, it always stuck at (+/-)50mA+/4.19xV

charge with USB, green lights up, restart, orange lights up, wait till green, restart, orange again.

Calibrations are not helping it at all

I'm now charging with charger and I don't think it helps...

green lights up, turn off the phone, plug in charger, light stays green, turn phone on and it's still 50+mA, restart, orange again.

Now it's 100% again with charger...

Should I leave it with charger for few more hours?

does it really helps? it seems mA never drops to 0 even with hours of charging...

Thank you.
[Desire HD General] danton11:
It should definitely work... When phone is off and on green light, unplug but don't restart, just plug back in while phone is off...

Edit - I just installed sense ics Rom. And for the first time ever my voltage was reading 4.206V instead of the constant 4.204V. Maybe you should try this Rom to see if you can charge your phone fully?

It's worth a shot I know how having battery problems can feel like your phone is ruined... This guide gave my phone a new lease of life...

[Desire HD General] NiGHTsC:
No, just can't get it to 0mA/4.2v.

Lowest I could get is 6mA/4.192v and that was before the phone-off-charge-with-charger.

I finally did what you said tonight and I can't remember how many times I plug/unplug-in the charger, but the orange-to-green mission seems to stop at 50secs

did it 4times and it always charge up at 50secs~ish.

So I decided to turn the phone on, it stays green but the mA is still not 0(+/-50mA+ as usual) neither is the voltage(4.1~ instead of 4.2v).

Restart phone, it drops to 98%.

Wait till 100%, restart again, drop to 98% again.

Wait till 100%, restart 3rd time, drop 99%.

Wait till 100%, restart 4th time, drop 99%.

Wait till 100%, restart 5th time, drop 99% again.

It seems the same as the 50sec phone-off-charge-with-charger, guess it will always drop to 99% immediately when unpluged cause of 4.1~v?

I'll try the only ICS Sense we have with HTC IS tomorrow night.

Failed.

No wifi+3G, no "Unknown sources" function.

no way I could track battery voltage/mA/usage in detail lol...

So I just install ICS rom but without Sense.

[ROM][MAR-04] IceColdSandwich 4.3 AOKP || COMMUNITY EDITION

Same thing, never goes to 0mA, with charger/USB, power on/off.

I have also notice one thing, when power off with charger, the longer green light stays with charger, the longer it has to charge up after unpluging for secs/mins.

Thank you.
[Desire HD General] tarroyo:
I tried this battery tweak and it does work, my battery is lasting hrs longer then it usually would!

I'm curious though why do you have to wait til current widget displays 0mA? Is the battery not fully charged when the green light turns on???
[Desire HD General] NiGHTsC:
It doesn't seems to be ROM problem.

Just installed yet another ROM, ARHD

Android Revolution HD™ 2.2.0 | High Quality & Performance | O/C | Legendary

All the same, voltage never goes up to 4.2v, mA never drop to 0mA

I've also tried BetterBatteryStats by chamonix and I still can't find a solution.

wakelocks don't seem to be the problem cause I have the same amount of wakeups on my WFS and it still stays at 0mA.

same APPs, almost identical ROM, but totally different results.

0mA and 20+mA, 4.2v and 4.192v

Thank you.
[Desire HD General] Dlog:
The light turns green before you hit 100%.

I guess that the light turns green as soon as the fast-charging is over. The more you get to 100% the slower the charging becomes.

Waiting for 0mA is used to ensure that the battery is at full capacity before deleting the battery log.

Same why people always say that you need to charge from 0% to 100% a few times: the bigger the charging cycle the more accurate the calculation is of what capacity your battery really has.

But i should mention that discharging to 0% only shortens the number of cycles your battery has and is ONLY needed for the aforementioned calculation. You don't get any "extra" battery life out of it.

[Desire HD General] RogerPodacter:
Only thing i can think is are you using the official htc battery? Ive seen aftermarket batteries use a cheaper version of the fuel gauge chip which is giving mA readings and thus give inflated mA readings. I experience this myself on my nexus one. The mA is triple what it should be.
