wp7 unknown battery drain

[toothfish]

For the past 2 nights i have been experiencing this

had 50% power left the night before...
after 6 hours sleep
phone is out of battery @@

Now that aint right, im guessing something is running under locked screen and iono what!!! but i always jump out of any program when im about to sleep too, so it cant be because of that

In the past, i could have standby time for a long period especially after one night. But the past two days when i woke up, it always ran out of battery!! Also when i charged my phone to full life, i sometimes come back after a hour or two to find it dead!!!

This has never happened before and im wondering what could be the cause of it.

In the past i could leave my wifi, bluetooth, location on and it would still last overnight and i wasnt running any program

It cant be because of alphajax right? I mean i did install that two nights ago :\

That is really weird, which phone do you have? I have the hd7 and get 2 days between charges most of the time. Have you tried uninstalling alphajax to see if that helps?

I use a HTC mozart 7

Im gonna try uninstalling a few apps to see if that helps or switch to my secondary battery pack

just to let you know i watch videos before i go to sleep and because its get so hot it drains battery faster, even though i had 50% after I finished watching it went all out in about 8 hours of sleep.

That sounds highly likely, i was playing a game before that, then left it alone for 1 hour, check still had 50% battery, and then went to sleep

woke up with a dead phone

I will confirm that when I have overworked my focus, ie several hours of video and games, the battery can get very hot and if I wait until I get the low power warning, plugging it into my laptop USB can't keep up with the drain.

ok this is ridiculous

in 3 hours i lost 30% power on standby

ITS ON BLOODY STANDBY!!! lol i cant figure out whats causing it. I didnt use the phone for anything at all then put it to charge till 100%. Started counting down time...

If I were you and you dont mind loodsing games aves etc, Id try a hard reset and if that doesnt solve the problem go to LG and ask them to fix it if there may be a fault.

Sorry I cant help further and Goodluck!

I've had this issue as well. This has been going on for months for me. Before NoDo and the pre-update.

Perhaps the battery isn't calibrated properly. Mine shoots down to 50% over the day but sometimes an hour or so after I hit fifty the battery goes critical then dies.

Battery Drain

I have the Samsung Focus. Pre NoDo I could get maybe 18 hrs in standby, and charging from USB on my computer was not happening. I had to plug it into the wall. If I actually used my phone for maps, calls, web or whatever I would get about 10 hr's depending how "how much I used it". This was with EVERYTHING turned off. Bluetooth, location services, feedback, anything and everthing I could disable. After NoDo, I get about 2 days, and now it will charge from my computers USB. Go figure.
All I can guess is there was some sort of corruption in the ROM.

Just a side note, does anybody know what "NoDo" stands for???



Answer: No Donuts

Before the February and March updates, I woke up one day to see my battery had drained from 100% to 0% in about 6 hours of sleep. After recovering from an angry awakening next morning, I paid a lot of attention to how the battery was draining. So I charged up to 100%, went to work on the tube as I always do, and noticed how after about 45 minutes, the battery was down to 50%. That was just some music playback and checking a few mobile websites.

In the end I remembered the day before I had installed two applications, one of them being Lyrics and the other one being a BPM (beats per minute) detector for getting the tempo of a music track. I decided to remove that application and, voilá, the battery drain stopped. I would have uninstalled the Lyrics app but this was already taking me to a decent power usage state, so I stopped there.

If I were you I would check recently installed apps to make sure you don't have a power drainer that's magically working in the background when you put the phone to sleep.

Did you disable feedback in settings. That extended my battery life considerably

I know what your going through, but i found the solution.
Your mobile data is constantly running to check for updates on the game and push notifications. Disable data connection whenever your not using it, and i swear you will see a massive improvement. I have a htc trophy and its notorious for its bad battery. I used to only get 4-6 hours out of it, and now i get 12-14, with WiFi.

That reminded me.... alphajax uses push (although i had disabled it) to notify the user if the other player had made a move...

It all seems LOGICAL that alphajax is the culprit here....

but i also have lyrics, how does that app affect the battery???
