Please help!: What could cause massive battery drains?

this is not settings related i'm fairly sure....
My battery lasts maybe 4 hrs with moderate use.
Tonightit went from 40% to 0% in 2 hours or so with almost no use!
The only symtom I have is that often the back of the phone gets VERY hot when charging...and I think at other times also.
Anything device/system related that could cause it?
thanks!

Any software that may be updating OTA too often and draining the battery?
It could be a defective battery.

There has been a problem with PocketToday software draining the battery. That problem has been fixed btw.

Pocket Today? i haven't heard of this software...can you provide a link? thx

Think it was the combination Pocketweather/Pocketbreeze from SBSH
Installing the newest versions solves the problem.

Have you checked to see if you had an active UMTS connection? That would most certainly do it.

I get about 4hrs of active use out of my Treo 750v, even though during the day it is checking emails every 10mins. I am reasonably happy with that. Battery life seems to be getting better as the battery is broken in.

Hi,
Along with UTMS, another classic is any sat nav software you have in use. You turn off the GPS receiver, hit the X button on the sat nav programme, but that only minimises it. It spends the rest of your battery hunting for a GPS unit that's turned off!

Well, Mine uses a lot of Power because of the Bad UMTS Receiption and therefore it always switches between 3G and GSM.
I wonder if it's possible to switch to GSM only mode as on my MDA Pro or other HTC devices.
Perhaps over the same registry key as it's possible on WM6 on the MDA Pro.
Does anyone have a hint on that?

Treo 750V Battery Drains
Hi Member
You dont need any hack you can tell the phone only to use GSM and not switch to UMT when avaliable.
From the start screen do the following
Start - Settings - Phone
Then go to the services tab and tap on band selection
The phone will at present be set on Auto
Change the top line from Auto to GSM and click on ok button
The handset will then only use the GSM signal and battery life will improve greatly.

BlackJack - Battery draining and unit gets HOT
I have the exact scnerio that was first mentioned in this string and I have not seen what could be causing this symptom.
1. BlackJack phone, not a BlackJackII
2. Battery charges for long periods of time, and within an hour it's displaying alerts that the battery is low.
3. The top of the phone gets HOT to the touch
4. The phone functions fully normally, but has no power.
5. I have multiple batteries, and the symptom is the same for all of them.
ATT basically said I was out of luck, since my warranty had expired.
Does ANYONE have a clue what could casuse this? Do I have any grounds to go back to ATT on?
The phone was RMA'd in January 2008, so I have had it for 6months.

Extend Battery Life on Touch Pro

Well i have 2 phones, a mogul (no service)
and my new htc touch pro.
Mogul has been in a drawer for 2 weeks now, and still STILL has battery life.
got me thinking. it has no service, so i put it into airplane mode..
so basically its just sitting there.
so i began to think, why does my HTC TP die in no time.
then i remembered, im running Gmail via Imap using flexmail.
basically this connects to the internet, and has a live connection to my gmail email.
so all day long its tracking my gmail,
i went into flexmail, and turned idle mode off, and set it to check email every 15 minutes.
i just did this right before i typed this, so i will post in the morning how it worked out.
if nothing at all this may inspire some of you to look at things your phone is doing that you didnt realize.
i update in morning.

I have mine set to check 2 accounts, a hotmail account every 4 hours and my pop account every 30 mins. I also have it set to auto disconnect data after 3 minutes idle, radio mode on so it can still receive calls. On average when I go to sleep for 8 hours and get up, I get a drop of 3%-4% battery during that time. Not bad at all. My tilt drops at least 8%-10% with the same setup.

ok, how do you have it set to drop data after idle time.
this may help in my quest.

I have mine disconnect after 1 min idle, check hotmail and regular e-mail once every two hours, and try to keep all extraneous programs from accessing Internet without me knowing. I can get up to about two days' normal usage (as of right now, 2:33pm, my battery is about 35% on its second day without a charge).

pssst how do you guys do this?

It seems everyday there is a new thread about a possible solution to the TP battery issue. I've ran the most basic test possible. Mogul by TP, both hard reset, both with radios off. Removed both from charger at 0700 before work. Got home at about 2100. Mogul was at %90 and TP was at %60.

Use Advanced Config. Left softkey brings up more options, to disconnect data after a certain time is one of them

What is a soft key? Sorry, I'm new to all this...

LOL! I laughed so hard I just had to comment. Just in case you were serious.
Soft Keys are the onscreen buttons usually at the very bottom of the screen. I.e. on the Home screen Calender and Contacts would be soft keys.
Except for the Raphael, on most HTC WinMo devices most softkeys have hardkey equivalents that are usually directly under the softkeys.

Well i now have a battery life of a few days (not phoning a lot or using Wifi alot) Also only a drop of 2-3% during the night.
I installed the RomeOS 1.51 whithout any modifications, but if i install the HTC Task manager my battery drains in 1 day (sometimes in 9 hours) so i'm not using that tool anymore

This isn't exactly relevant to the email conversation, and I suppose I could find one of the other 300 battery threads to post this in, but I made a bit of an accidental discovery too.
I had to make a trip for about 10 days and chose to only take my other phone with me. I left the fuze fully charged and without the sim card in, and with gps, wi-fi, and bluetooth turned off (all radio stuff was off). When I got back, at least 11 days total time gone, the battery was sitting at either 66% or 76% (was a few weeks back, I forget)
Not a huge revelation since there should be virtually no power drain with screen off and no active radio, but it further enforces the theory that the radio is a prime suspect for battery drain...and radio roms in particular are worth testing.

I agree that the drain has to do with the Radio.. I have a sprint touch pro and it will drain in a couple hours..
I left it sitting on the table a couple days ago, It was sitting for 2 days and when I checked it it was only down to 60% I also had bluetooth and wifi turned ON. The phone radio was turned off.
I thought the phone was turned off so i did not mean to test it like this but i thought it is worth mentioning.
wifi on and connected
bluetooth on but nothing connected
Phone radio turned off.
2 days sitting and the battery only down to 60%
This phone usually drains to 40% in 4 hours just sitting on standby in my pocket. Does this not proove it is the sprint radio killing the phone.

If you're running a default ROM and haven't changed the power saving settings, wifi turns off when the device auto-sleeps.. bluetooth remains on but by it's design its power draw is very minimal without an active connection.
The phone radio maintains a constant connection to the cell towers, and it doesn't have a deep sleep mode (it has to remain ready to wake the rest of the phone up when a call/sms/mms comes in) - if for whatever reason it's signal drops below a treshold, and it starts hunting for different towers etc. it'll bump it's transmitter up to full power for a period of time..
As long as you're maintaining an active connection to the cell tower, there's gonna be power drain. On the GSM side of things you can minimize it by locking the phone to GSM until you need 3G, the nature of GSM allows it to use less power both in idle and active transmission modes than WCDMA.

As I have tested and re-tested different ways to conserve battery life I can honestly say there is no miracle cure to make it last longer. If you're burning through lots of data (via 3G, HSDPA, etc) you're gonna have even less life. Moderation in usage seems to work best although that's not a viable option for most of us, myself included. With all the talk about better drivers and power plans, has anyone looked at the possability of the battery being crappy? Could it simply be not enough juice for a device of this caliber?

You're surprised that this person doesn't know what a softkey is, yet you can't speak english correctly...

i don't use data on my phone during the day and I only use about 3-4% battery power a day with a couple of texts in there.

You're getting unusually good life. In a good week, I get about two days out of a single charge. When I'm not using several features, the battery drain is approximately 30%-40% in one day. This would be a light workday. More times than not, the drain is around 60%-70%.

Battery Helping

HI all Last night I Fully charged my HTC 3G and sleep but when I wake up i see it have 30% of battery .....70% gone
anyone know what is the problem ???????????????

sorry I don't know what happen I post tow topic and I cant remove IT please remove one I am really sorry

This might sound stupid, but did you make sure that the other end of your charger was connected?
Alternatively, perform a soft reset and see if your battery level changes back to normal.

It may be a problem with the battery..... otherwise it could be alot of different things.
if your internet, gps, backlight was on, where receiving text messages, receiving emails, if you have push mail set up, if you have weather updating all the time.... ect ect ect
How long where you out?

Sounds like gps was left on or perhaps wifi... maybe bluetooth. Some roms on here have been optimized to reduce battery consumption. Some are like night and day. Some of the older roms for my kaiser sucked the soul out of my battery. The newer ones are barely molesting it. I would try using Battery Status Today plugin to see how many ma you are consuming during idle... with bluetooth wifi and gps and post results. I remember i had a MOTO Q Global and until i fixed it with com port hack the gps was enable all the time! barely got 4-5 hours out of the extended battery... Just throwing that out there. I also find it funny that my kaiser uses so much power that it can not charged through usb from computer unless its in standby. If i try to use it tethered to the computer you see it slowly but surely drop the battery % . Everythings turned off or down to minimum in a non 3G area go figure.

Even if all the radio devices were on, wouldn't the device be taking power from the AC rather than from the battery? I have had my device cradled at full blast a few times (not overnight though), but battery did not go down...
It could be a problem with the battery just like Joel stated...
I am only assuming that you were charging the unit overnight. Sorry if I am misreading your post.
BTW, do you have S2U2 installed? It has happened to me that the device wakes up due to an event reminder and the screen does not turn off because of S2U2. I am running 1.37.
Just throwing it out there.

I do it again tonight and turn off all thing and see what happen then tell you
I have one another question whaaaaaaaaaaay anyone don't cook room for HTC ?3G

Can't Believe my Touch Pro Battery Backup

Well, I am not complaining. I am surprised and I am here to share with you all my battery backup.
I have last charged my phone 4 days back and I still have half of that green bar left.
Its been some 8 months or more that I am using my phone and the battery backup never lasted more than a Day. I use to charge every night and the battery use to drop to less than 25% by the late night. I didn't panic though. I use to read about others experience on the battery backup and given the features and usefulness of the phone, i have no regrets what so ever.
I didnt upgrade anything on my phone including the ROM,
But I am quite surprised that its been 4days that I last charged and the battery is still at 50% and my usage didn't change a bit.
Am I going to get the backup that the HTC spec talks about?
Guess what? my GPRS is not working for some reason since a week now and i believe that is helping the battery. When the GPRS was working, it always use to be on air and even if I disconnect, it reconnects and stays that way because of automatic email checking.
But if it is really the GPRS, how do i live without that when the device itself is build for messaging and emailing? How do I optimize this?
What do you think ?

What "battery backup" are you using? Is this an external battery pack that you plug in?

No stevens, i am using the default battery that came with the HTC.
By saying Battery backup, i mean the standby time.

In diamond tweak you can choose to disconnect your data connection after not using it for 10 sec. through to 10 min. Try this, works just fine on my TP.

pointless thread please delete
of course the battery lasts if the radio is turned off

Automatic email checking uses a LOT of power so it is not wonder your battery lasts longer when it is disabled.

I'm not talking about turning the radio off, I'm talking about turning data connection (GPRS, EDGE, UMTS, HSDPA) off. It's a different thing mate.

also turning off 3g will make the battery last longer since it doesn't constantly look for 3g signal

as the guys here stated, as long as you turn off (or that they're off by default) the data connections and gps,your battery should last a good amount of time.

Phone like to haz p0wer all the time.

I am running current widget. This phone is a beast and eats 250mA while idle while my OG droid only was taking 20-30mA. no wonder this sucker dies in 4 hours

That shouldn't be that high when idle. I'm doing idle power tests right now, all the time in fact, on my nexus. Checked the thunderbolt and inspire at the store. At least they seem more efficient with screen on, hitting around 430mA at max brightness. My nexus will hit 750mA which drives me nuts.
I'm comparing ginger bread idle power, and Google seems to have made enormous improvements. Idle current draw is now at 8 mA, where on froyo for me its around 18mA. More testing needed.
But I feel that slcd screen is way way better for power than the amoled since most uses show white color anyway.

well its pretty consistent idle power draw of 200-250. i have 4G on and syncing on as well. When i am using the phone with the screen on i average around 450-500. when i turn of 4G and have good 3G signal i can get the phone around 45mA

45mA is still high. I just wiped my phone because I'm averaging 50mA idle all the time no matter what. On this clean install I'm now at 15mA very consistently. But what's driving me nuts is I loaded stock ginger bread, and that ROM stays dead even at freaking 4 - 7mA. It's beautiful, my battery lasts incredibly long on it. But switching back to cyan7 I can't get below 14mA, and its driving me mad.
I just swapped ROMs again a few hours ago to do more tests. I hacked the nexus battery driver to do some useful tests. Wonder if the thunderbolt uses the same driver.

My idle draw is an average 40 with 4G. I'm using the current widget.
It also draws the same on airplane mode. Something is screwed up somewhere...

Your posts aren't very informative for someone trying to compare.
What apps are you running background, which services (sync, location, etc), which radios on (wifi sleep policy, BT on, 4G/3G area, etc), screen brightness settings? Even the app will have an impact on draw, since keeping a log file will cause some juice drain each time the log is written, so update interval is probably necessary for the discussion to be meaningful.
You're getting your numbers from the log and when the phone is actually truly idle (ie. untouched, screen off) for a while?
Not criticizing at all, but these kind of discussions can end up just frustrating folks because of ambiguities...kind of like the posts where someone says (I get 5 days on my battery with "moderate use", and it turns out that guy's idea of "moderate use" means it sits untouched all day except a couple of minutes browsing).
I just installed the current widget out of curiosity, so not much data to go on, but with the screen on 50% brigthness, wifi on, BT on, sync on, several apps having been opened I saw about 140mah. Turned the brightness down to minimum and it dropped to 76, then 45. Let the phone idle scree off for a few minutes, and it was showing 32 when I first turned it back on.
My log shows that during the idle period for a couple of minutes, the phone was drawing between 30 and 40 each pull (every ten seconds).

Ill post a copy of my Log later on. Right now the results wouldnt be fair because i am at my parents place and their house is made of some material where you go from 3 to 0 bars of reception when you walk in the door. But usually my general setup is 3g/4g on wifi off, BT on but not connected to anything, GPS on but not actively lookin for sataillites, and then a bunch of my regular apps. I mean let me put it like this. in my first post i discuss the difference i have seen in current consumption between the TB and my OG droid. The phones are set up EXACTLY the same with the same programs running in the background. The only difference is the TB has that extra 4G radio. I live in West LA so generally the coverage should be 100% 3g/4g. anyhow ill get a copy of the log.

my currentwidget is almost always above 100mA and ive got 4g off, wifi off, gps off, BT off, no apps running etc. very frustrating to see this phone die in 6 hours no matter what

This has been my experience also. my history from last night showed a peak of about 400mah discharge and a min of about 120 mah discharge. Not sure what is going on.

I have wifi off, bt off, gps off(using vzw location services though), with words with friends, double twist, battery booster, goog voice, lookout, bat indicator service, myphonemrules, simple service, craigs checker service, weather toggle widgets, nobars, night time service, battery monitor widget, and swiftkey, the rest are vzw bloatware services or htc processes in the background. Backlight is at about 30-40, and timeout is set to about 1 min. Since the last restart I have gotten as low as -50mah and max is about -350. I can't say what all was running during the night because I changed few things this morn to try and fix my drain, which as seemed to help, but not a lot.
Attached is a copy of my history since 3/24.

Once we are able to undervolt our kernel, our idle usage should drop significantly. Until then, I'm keeping a charger handy and waiting for my eBay batteries to get here, lol.

I have the extended battery, which I can't use with my case of course, if I really need it. But I like having a case on my phone because I shattered the screen on my D2 a week after I got my last one. Not trying to do that with the TB.

so to revisit this post a couple months in.. i am on the new GB leak. still idle at 40mA still sucking power like nobodys business.. wtf
