TyTN - excessive battery drain

Hi all,
I've got a serious problem with my Hermes:
The Battery is drained very quickly and becomes very warm. According to acbPowerMeter with 3G OFF, WiFi OFF, Bluetooth OFF and no running programs its drawing somewhere between 350-400mA (!) in Standby mode . But now the strange thing: when i switch WiFi ON the current drops to about 80-130mA sometimes 40mA or less.

I already searched the forum but couldn't find any solution for this.
ROM: Pays ROM 2.15 GER
RADIO: 1.50.00.00
same thing with
ROM: HTC 3.54.257.2 GER
RADIO 1.47.00.10

Obviously you know you need to replace your battery immediately.
I'm willing to bet that you've configure your WiFi to search for a 'hidden' SSID (then you switched the power setting to 'performance', instead of the default power saver mode).

The Device and battery are brand new. (Its a replacement for another TyTN which had a defective camera and also drained the Battery very quickly).
WiFi is set to energy save mode and it isn't searching for hidden networks. The thing is when WiFi is OFF the device drains more current than with Active WiFi!

Sorry, unfortunately i can't find any useful information in there.

Sorry if this doesn't belong to this thread, but I have a similar problem:
After using WiFi and turning it off, my TyTN's battery starts getting very warm and drains very quickly. I turn it off, remove the battery for a few minutes, then put it back and power the device on, but in a few hours the battery heats up again and drains completely very soon. I have no idea what to do with this... Any advice?

No, ideas? Help would be much appreciated
I noticed that sometimes my TyTN is working nearly normal, that means it draws 15-20mA with WLAN OFF, i switch WLAN to ON: 150mA, but then when i switch WLAN OFF it starts drawing 350-400 or more again

V87, please post the link to the tool you are using to measure how much power is being drawn from the battery. I want to make comparisons with my unit, just to be sure before I respond

It came together with my rom (pays 2.15)

Hey all,
I've been lurking for a while, just picked up a 8525, and noticed some of the same issues. Occasionally, I'll notice the battery getting warm, and after popping up acb power meter, the device is drawing 350-400ma. Turn on wifi, back down to 40-70ma. Wifi off, back up to enormous drain.
I'll shut the device off (long press power button), remove the battery, wait about 5-10 minutes to let everything cool off. Install device, power up, all good.
It's an intermittent issue, and I haven't been able to nail down what triggers the power draw. I'm still experimenting, and will post if I am able to notice any consistency in triggering the issue.

Hey, count me in with that same issue to. I thought it was a battery/charger problem after only getting about an hour out of a batter, but after a new battery and charger, I tried the battery meter program I saw that it was drawing 350-400mA while doing nothing and getting quite warm, but if I enable wireless it drops to 80-90mA. If there was something in that manual that is no longer posted. I would greatly appreciate knowing it.

Unfortunately no. the service manual that was posted includes a procedure for checking the battery voltage with a multi-meter and a test procedure for the logic board that can't be done without service equipment.
I have since sent my TyTN to be serviced for the battery drain issue, and am waiting to get it returned.

I had a similar issue to this. Got my Vario II, charged it up overnight. Next day took it off charge and headed for work. Got to work about 45 minutes later and the phone felt really hot in my pocket. Battery was down to 10%. Same thing occurred over next 2 days so I sent it back, got a replacement and all was good.

After playing with this unit, I've noticed that the high-drain/hot battery starts happening after using a program that consumes high CPU (AOE, flashing, etc). After powering down and removing the battery for a few minutes, and allowing everything to cool down, everything appears ok.
This could be exacerbated by loading the system while charging.
Any EE's with ideas?

Well my TyTN's back from the shop. They replaced the logic board. Hopefully this one won't have any issues

Maybe this was caused by an active 3G connection. I am currently streaming audio over 3G and the power drain goes up to 550mA. The battery becomes very warm as well, which is normal for 3G usage afaik. If you enable wifi, maybe the 3G connection stops and tries to switch to wifi, causing a considerable drop in power drain.
I also noticed that a soft-reset helps bring battery drain down as well. As if windows or the device keeps using power for some background process or something. Not sure if that if a software or hardware related problem tho.

[x10 Autoshutdown issue] Temporary fix?, Sd cards bad sectors?

First i hope u understand me.!! (My english is not that good....)
My phone was suffering from the same thing (for 3 months more less)...
It was really annoying because my phone started tu shutdown after 1-3 minutes of use. but yesterday i found that it was working as intended after i have formated my sd card..
I have been making some researches about this problem and i found that the problem may be your sd card.
I suggest u to format it in slow mode.
Restore device defaults

I hope this work for u too, this bug is really annoying....
edit1 - try playing a game for at least 15-20 minutes in order to know if this worked for u.
let me know if this worked......

hm, my phone shuts down randomly after about 3 hours of usage. i'll give this a try when i get back home.

Hmm, the shutdown issue could be caused by using custom ROM or custom kernel but not usually caused by SDCARD.Maybe it is bug of your ROM. Have you try another ROM and it is the same?
Sent from Sony Ericsson Xperia X10 - Stock Android 2.3.3 Modded

is the same ..
edit - is only a temporary fix, after a manual reboot it start to shutdown again... at least for me.

Same problem here with my x10 w/ stock clock interactiveX, and class 4 sdhc on any kernel or rom. My wifes x10 is perfect with class 2 sdhc, doomkernel, interactiveX, unlocked sim and BL, OC'd to 1.22ghz (temp control using setcpu profiles). my problematic x10 is similar spec to wifes but with fat batt, and aftermarket sd card.
I slow formatted twice, still same prob, so replaced sd card, but still restarts. especially when using youtube, heavy internet, gaming, and general use while charging. SO, after observations, i suspect: 1 fat mugen battery is trapping heat under it, 2 bad sectors in RAM, 3 general hardware fatigue, 4 another sd card with bad sectors. since those are as common denominators during heavy use and caching...
I'm gonna go back to stock batt, and try another sd. if problem persists, its gonna be an excuse fo either a sgs2 or nexusprime

The device does shutdown itself if:
Temperature of the battery exceeds somewhere around 42-45 degree Celsius (or 107-113 farenheit)
and/or:
Voltage of the battery drops below 3.0 volts (Or what is set as 0% battery capacity for android devices)
Some third party batteries can show a charge level above 3 volts (above 0%), yet be "out of juice". It's known to those batteries that claims themselves to have more capacity compared to the original batteries. In fact, they don't. They only got the voltage "skewed up" in order to appear as a higher capacity battery.
(Most common among "higher capacity" batteries that have the same size as the original.)

My phone shuts down when the battery gets empty

My phone has been shutting of due to battery drain latley, ill be around 30 or 40% leave it sit, then when i come back ill hear it vibrate, hit the unlock button just in time to see the battery indicator at 1%, the trick is when i power back up the phone is back at 30 or 40% battery life again, i've calibrated, wiped stats but it keeps doing it.

I am in discussions with 3 UK and they have informed me that the issue, at least in my case, is down to me dropping the phone. I have told them that is the case, but they have insisted that a cracked glue joint is to blame. How many people have actually suffered from this fault, and what networks are you on?

What does the SDCard has to do with anything? The system is not even in the SD card.

i did it on purpose lol. Let's see the reaction of the others. Lol

Hey..
Did you ever Google "x10 random reboots "?
You will be surprised, but not the nice kind of way.
They say that it's a problem of the Mainboard so only Sony can fix this.
I have the same problem but not that often and only while playing games.
Greetings!
Sent from my X10i using XDA

Get a new battery
I used to have problems with my X10 (SO-01b) suddenly shutting down.
Typically the cause (from what i've read on XDA) is:
1.) It gets too hot
2.) need to recalibrate your battery stats
3.) you need a new battery
I spent a couple months testing out different things and found my battery's voltage would drop too low even when it had enough "charge"
The solution was to just buy a new battery; The new battery cost was really cheap from my carrier (about the cost of 3 to 4 starbucks coffees)
X10 launched over 2 years now; If you haven't replaced your battery by now, you're probably overdue for it (or get a new phone)

Fixed
I reformatted hubby's sd card 4 times in a row now no reboot issue. Thanks for all the great info!

I am suffering from this to. I will try a new battery. With me, the phone dropped a few times (battery cover is even cracked...). It is 2j+ old so it could well be the battery.

[Q] Newly rooted NC having battery issues...

Got a NC for xmas and rooted it and installed cm7.1 and everything seems to be working well except the battery. I went under battery use and i see that Display is eating about 60% of my battery! I turned brightness down to 25%-ish and i have also turned off everything i am not using but the problem still persists. I have seen people saying i need to do some kind of battery calibration but i do not know how to do this. If someone can help me get this issue resolved it would be greatly appreciated.

Unfortunately, you can only do so much about screen battery consumption. Turn brightness down as far as is comfortable, but personally, I don't want to give up the vibrant display. I find 25% is usually adequate indoors. With my screen ON, it consumes roughly 10% per hour of use, which equates to 8-10 hours of use -- not bad. With the screen OFF, it sips less than 1% per hour, and often less than that over a few hours.
Keep in mind, you WANT screen battery consumption to be the largest value. That means it's nice and idle when you're not using it. If something else is using a significant amount of battery, that may be something you can do something about.
As to calibration, I do find that Android battery gauges often are incorrect until you let the battery completely discharge from a full charge once. Then it's calibrated correctly. Of course, that's not recommended for battery health, so don't do it compulsively. I had a device that showed 1% battery remaining for 3 hours while I played MP3 audio.

I wish i was getting 10% an hour, im getting roughly 20% I now have another issue that i did not have this morning, i can not connect to my computer via USB. Is there a setting i might have turned off in my fit to increase battery life?

@Lsjreadingpa Renaming /system/app/phone.apk to phone.bak is a commonly undertaken act that can significantly lower battery usage. Also, you can turn off Account Sync when not using it actively, as it increases battery drain when you are not actively using the NC.
As far as the USB is concerned, make sure you have USB debugging checked in the settings menu.

How do i rename it? Also a bit of an update, i have turned off syncing as well as alot of the other options and i am losing 5%/20min

Last night I cleared cache and battery stats and let the battery die and then charged it to full this morning. Like I said above I turned off syncing and gps as well as removing beautiful Widgets. I just don't know what else to do. I'm attatching two screenshots showing my battery use in the last hour.

You can use Spare Parts to check what's consuming battery if your DOMAIN supports it.

Anyone able to help?

Are you concerned about battery consumption while you're using it? If so, then your brightness and the applications you're running are going to determine your battery life.
If it's battery consumption while idle (screen off) that you're concerned about, then do you have any widgets that do network access? I found that my battery life dramatically improved when I was no longer using the Twitter widget.
In Spare Parts you can go to Battery History, then check 'Partial Wake Usage'... this can help you figure out if there's an application that's preventing the device from going to sleep.

I would recommend trying a newer nightly or the Mirage/Kang build found in the Android Dev sub-forum here. I forget when they were added, but there were a few big improvements to CM7 a while ago to help with battery life.

Battery consumption while using it is kinda of scary because it drops like a brick. While sleeping, which i don't think it was doing, seemed to get better after i removed beautiful widgets. How different is the Kang build?

The Kang build has an updated kernel and other updates since the last CM7 nightly. It's supposed to fix an SOD issue. I've been running it for a while and am very happy with the battery life.
Like others have said, battery life while using it would most likely be helped by adjusting the display brightness, kernel settings and/or stopping "rogue" apps. You can see the kernel settings by going into the Settings Menu, then Cyanogenmod Settings then Performance. I use the InteractiveX governor (I believe "Performance" is the one that keeps the CPU ramped up constantly) with the highest overclock.

[Test] Battery Draining

Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)
Screen brightness: Auto
I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.

Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though

If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.

Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%

Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time

A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.

Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.

An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.

I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.

[Q] 15 - 20% battery drain over 8 hours while idle/sleep mode, any ideas?

Hey guys. I just got a Nexus 7 recently (sold used, but "like new", description said it was used briefly for a day and then packed back in the box again). It was working really well until I flashed this kernel. I had CM10.1 on it for a while and flashed that kernel so I could use CIFS.
After I tried this, I saw the the battery had gone from around 75% to 55% one night (over 8 hours). This is much worse than it was before, where it would only drain around 3%, or at most 5%.
I understand that my issue is probably simple: Just flash a different/old kernel or a new ROM and see if it helps. But I was wondering if there's a way to see specifically what is draining the battery. I tried getting Battery Analyzer, but says that "android keyboard" uses the most CPU, and the actual battery settings says, other than the screen, that "Media Server" is using 8% of the battery, as well as System Idle or something.
I don't know what this means exactly. But I do want to know a couple of things:
1. How can I know for sure what is causing the battery drain. Is there any way to figure it out?
2. How can I troubleshoot this, that is, I want to try disabling features and seeing how much the battery drains after that.
In the mean time, I'm gonna flash a different ROM and I'm sure that'll fix it for now. But I'll have a NAND backup just in case.

Install. Follow directions. Post log as an attachment into their thread asking for help.
High loss while idle implies wakelocks and possibly CPU activity.

I actually found this before and tried it. It showed something with Google+ being highest with partial wakelocks, though I didn't fully understand it. I ended up removing the G+ widget from my home screen on a whim and it seemed to help a lot, only reduced 3% over 8 hours. I'd like to improve even that if possible, but that's how it was when I got it, so I'm really pleased with that. And hopefully it's not a fluke, I'll have to see what happens another night.
Thanks anyway. I'll monitor it more and see if there's anything else I can do.

I use System Tuner to set the off-screen CPU max to 384, seems to help a lot.

May have well just have told him to only touch his tablet on even numbered dates and to only charge it face down on an espresso colored end table. They have the same effect on battery charge and indication that wiping battery stats does. The myth of wiping battery stats was clearly and concisely given an official debunking about a year and a half ago. If anything, wiping battery stats will hinder the OP, not help.

It's not important, as it does nothing for battery life.
