I think I have a problem with the battery drain of my HD2 wjen in standby mode: as you can see from the attached log it never goes lower than -75mA, even with pushmail off...
It started like this with CHT 2.0 installed... could it be?
Yeah, CHT could be a reason, some stock ROMs seem to be a bit critical for this great piece of software.
Plus, it can also depend on what extensions and widgets you added to CHT...
After all, not so easy to find out. My HD2 runs like 2 days at normal usage (some phone usage, some texting, some mail sync over wlan, sometimes even with some navigation).
Please also make sure to try different Radio ROMs... or re-flash, or whatever. You´ll find several threads here with similar issues and various solutions and ideas.

yeah but why would CHT affect battery life when in standby? I am worried about the -75mA drainage in standby mode...

CHT in itself does not consume much power (if at all), I have CHT 2.0, and idle consumption is in 2-8 mA range (with GPRS and pushmail working).
Maybe you have some of the CHT monitoring widgets active?
If so, I'd suggest checking power consumption with those widgets turned off,
or even checking what is the power consumption without Sense

I have no monitoring widgets..
Could it be that I turned on the bluetooth discovering mode in cht editor? What does this option do exactly?

rather not, discoverable mode means normal bluetooth operation, except that your presence is not hidden from other devices (more info in wiki here)
as for the power consumption, it's definitely too high,
you seem to use some battery logging app, does it also show the current in real time?
if not, you could install BattClock, to check what the mA level after you wake the device from idle state (just to have second opinion/confirmation)
besides that you can either search this forum for some hints (the problem was raised several times), and/or start searching for the reason by elimination (check mA usage w/o Sense, try turning off the auto update of services like weather, contacts, FX etc.), check list of running processes with the Dotfred's Task Manager - trying to find which may be unnecessary

Hi,
when was the last time you formatted your SD card? A malfunctioning/severely defragmented SD card can cause a huge battery drainage. I'm pretty sure that this is your main problem. To solve it, follow this way:
1. Shut down device and remove SD Card
2. Insert SD Card into Card reader and insert to PC. Wait untill you see the Windows screen that says: automatically play/open this device and choose open folders.
3. Backup the content of your Card to a self named folder on your PC
4. Click another station than the SD card
5. Go back to SC card and right click it and choose formatting (slow mode)
6. After finishing this formatting, safely remove the Card from your PC and reinsert into device.
7. Boot device and format SD Card again with SD formatting tool (Windows - Tools - SD Formatting Tool).
8. Take out SD card and reinsert in PC and restore data fromm the self named folder.
9. Reinsert SD card in device and soft reset.
Done

Hi,
I have alreday tried that with no benefit... Only difference was that I formatted it diurectly into phone, skipping step 5: why do I need to format SD card on pc as well, before formatting on phone?
BTW, why would the SD card drain the phone while in standby?
I have also tried disabling sense and monitoring again, and still I have a fixed -75mA drain in standby...
Here's a list of running processes:

JBlendDaemon > what is this?
CommManager
battclock > this was installed already before having batt problems
BTTrayCE
alarmPal > this was installed already before having batt problems

A SD Card uses enery/battery power, when SD card dysfunctions or contains errors or is heavily defragmented, they all can lead to several severe problems, f.i. a huge battery drain even in standby.
The reason why you have to format your SD card first in PC, is that the Windows PC formatting tool does a very much more thorough job than then device's one (only compare the time they need to finish this process!!) and erases the Card totally whilst also repairing posssible errors or skipping and excluding bad sectors. So skipping this and only using device tool might not solve you're problem. The formatting afterwards with device's tool is only meant to prepare the card for the device's system. So, if I were you I would format SD Card with PC first and monitor battery usage. Be not surprised when the usage diminishes a lot.

ok thanks: i have done that and now will monitor usage...
by the way, i am using BatLog: is this a good tool?

then just to verify that I use it in the proper way:
- I launch batlog
- I set interval to 10 seconds
- I set the log name
- I start the log
- I minimize batlog
- I turn off the screen
is this correct?

I am still doing a few tests: ALL ON, ALL OFF, DATA OFF, DATA ON BUT PUSHMAIL OFF.
Then i wanna try with SD out, just to exclude SD.
My real problem is that overnight, with data on but pushmail off, it drain 20% in 8 hours... way too much...

You are absolutely right on that, this drainage is far too much. My overnight drainage in standby mode (so connection data on) is max 3-4%. If drainage without SD card is far less then now, I would advice you to buy a new one because either it's severely damaged or corrupt, even after formatting.
BTW, do not worry too much about Battlog, just look at your battery% that you have left over after a certain amount of time.
Good luck and regards, Kuzibri

OK,
after two tests (but I'd like to do a few more)...
-1- GSM ON, DATA ON, PUSMAIL OFF, SD IN, NO ACTIVITY AT ALL
23:00 @ 50%
07:30 @ 15%
lost 35% in 8.5h that is 4.1% per h
-2- GSM ON, DATA ON, PUSMAIL OFF, SD IN, 2 CALLS and 10 MINS BROWSING in 3G
10:00 @ 100%
19:00 @ 80%
lost 20% in 9h that is 2.2% per h
So for the moment it looks like it's the SD, but I'll try again tonight removing the SD while the phone is in stand by with no activity (same conditions as test 1)

Bad news... 28% in 10 hours overnight, with SD out and pushmail off.
Cannot be sd at this point... Could it be that after 1 year and 3 months the battery is already dying? This would explain the -75mA drain when in standby.
What's strange is that now I'm charging the batt and ir went from 41% to 57% in 15 minutes...

so, 10h overnight, SD IN but DATA CONNECTION DISABLED and it went from 100% to 95%...
I guess this means only two things: it's not the SD, teher must be something which uses the data connection constantly... how can I find it out?
PS: weather is set every 3 hours, facebook every 2 hours, nothing else...
I purchased a WiFi 7.7 on Saturday and have been having some real problems with battery drain, even when it's not in use (e.g. Overnight) to the point where the time gets reset to 12AM and the date to January 1, 2000. I don't appear to lose any apps or home screen settings etc.
In the end, I actually returned the first one I bought, as I was convinced I had a faulty battery.bathe battery issue seemed worse with the first one as it would go from 90% to zero overnight, on standby.
I have a Lexar class 10 microsd in the slot but have very little in the way of apps installed and nothing running (apps) overnight.
Has anyone else seen this behavior?
J.
maybe try not putting your sdcard and test it overnight, i read somewhere here that a faulty sdcard can cause problems

Totally agree with such cause , as i personally have encountered this with my previous HTC HD2 & the cause was the micro sd card.
Hmm, I did read about sd cards possibly causing battery issues but I've not heard of anyone else, with a 7.7, that sees the date and time reset like my device.
Interestingly, a folder called LOST.DIR is created each time the sd card is formatted in the tab; does this point towards a definite card problem?
When I've checked battery usage before it showed that the android os was the hog but previously it was the screen. Can't remember where I saw that one.
I have another (8GB) sd card so will see how I go with that one and report back.
J.
normal
The LOST.DIR is allway created so thats normal, try resetting to factory default and remove the memory card and use it s litte to test it. If that does not work i would return it
The LOST directory it's part of the file system and can contain data which has become unlinked in error. Ignore it, certain tools can use it to recover from errors but in practice your not likely to need it.
I tried unmounting my class 4 Kingston but it seems any power leakage is negligible for me--I checked using battery monitoring tool.

Have exactly the same issue with my 7.7
Since owning a tab 7.7 (3G) for about 6 weeks, I have had the sudden overnight drop in battery occur on 5 occasions. Most nights it will drop only 3% on standby overnight but on these occasions it will inexplicably go from 80 or 90% to totally flat in the morning. On 2 of the 5 occasions the date and time have reset. The battery monitoring of the apps "BetterBatteryStats and "SystemPanel" do not show anything that can be interpreted sensibly when this occurs.
I too have a microSD card (Patriot class 10) in my tab and I will now take it out and see if the problem persists.
Similar problem. When sd card is in the slot my tab drains battery very quickly, even when sleeping. (20% per night). Without the battery just 2% per night.
update
update on my issue...
Ive noticed that the battery drain is also accompanied by what is termed "sleep of death" so i downloaded something called "auto airplane mode" (by DON) which switches the wifi off when the sreen is off and the tab "sleeps". So far, so good.
I formatted the 32gb card so will keep testing and update if problems persist.
J.
Quick update...
Since installing that app, I have had ZERO issues.
Hi
I have a Huawei watch and a Samsung Galaxy S7 edge. Both were working fine until a few days when i noticed that my phone battery was draining more quickly. I also noticed that my watch battery was draining at an alarming rate. So I reset the watch to factory settings. Things worked for a few hours then it all happened again. I used Wireshack to read the log of the bluetooth (Bt wakelock was draining my phone) and i noticed that the contacts are being constantly being updated on t he watch. I looked at the watch storage and the contacts storage was at 100 Mb , however, my phone contacts storage was just 30 Mb!
I deleted my phone contacts and sync again then i factory reset my watch again. However, the problem is not gone. The contacts storage on my phone is increasing in size gradually and the constant sync is draining both batteries.
Is there a way so i can stop my watch from synchronizing the contacts?

Try disabling the permissions for contact storage in watch and observe. It is found in settings- permissions.
I will try that if the problem reappears, Thanks.
Meanwhile, i got mad and i factory reset both the phone and watch!! i will wait and see what happens
