Welcome to Vodafone Community
To be honest I haven't got that much installed. A few games and apps but nothing major and I don't use facebook or twitter either.
My sync options are also set at the maximum time allowed so I'm sure it can't be that either.
I have a samsung galaxy tab, so I thought I had managed to control the battery with android quite well but this seems to be something else. I don't know how to explain losing 50% battery with the phone turned off!
Thanks for your post here. I’m sorry to hear that you are having this problem too. I appreciate how frustrating this must be for you.
Unfortunately, if you have a fault with your phone/battery (which you would appear to have) then the only option is to send the device away for repair. You can get all the information you need on how to do this by following the link in Lee’s post above. I'm sure that once you do this, you'll have a 100% fully functioning phone once again
Please let me know how you get on and if you have any more questions we’ll be happy to help you further

Thank you for your replies NeoBlade and Wayne,
I've just installed system panel and I will give it a few days.
I have no task manager except for the one already on the phone.
I was just uninstalling some apps when the phone turned off. I turned it back on and it asked me to select a time zone!
I don't know what to do. This rapid drain has happened about three times since I had it but it doesn't leave you with much confidence!
I'll report back soon.
Hmm... It sounds like a bad battery to me but let me know how it goes. I forgot to ask, is it on the latest firmware as well? Make sure the battery is over 50% before flashing or have it connected to charge while doing the update. Does it heat up so its very warm to the touch?
Yep, latest firmware. The heat seems to build depending on what I'm using. If playing a game for an hour it can get quite warm on the back around the centre and bottom.
Perhaps I will send it in and might get a new battery. I don't mind nursing the battery through the day but the total randomness is frustrating.
Right, it has happened again!
Nearly exactly the same as last time. First checked at 4:30 pm after a full charge at 2pm, and it was down to 60%.
Checked again at 7pm and it was down to 10% without me using it once.
Task manager shows nothing running but system monitor has about 20 programs running in the background such as calendar, dock mode, gmail, htc message uploader, htc report agent, internet, mail, market, messages, my uploads, settings, shop, status bar, touch input and wallpaper.
Is this normal for android?
I'll admit to not delving too deep with my Tab as my partner stole it most of the time!
If this is normal then I suppose i will have to go the dreaded repair route!
There's now a Mugen power battery for the Sensation, 1800 instead of 1520 maH, came out earlier this month.
Mugen power batteries are supposed to be really good.
Anyone tried one in a Sensation yet?
Thanks for coming back to us here. I’m sorry to hear that you are still having this problem. I understand how annoying this must be.
I can’t confirm exactly what programs should be running in the background as I don’t personally own an Android handset, however I’m sure NeoBlade will be happy to confirm this.
Even with those applications running, the battery drain still seems a bit extreme. I’d still recommend the repair option.
Please let me know how you get on and if you need anything else, let me know.

I have just started having this problem.
I've had my Sensation about two months, And I've found the battery to be OK. Drains pretty quickly with heavy use, but it lasts a day, And that's fine with me.
Lately though (past few days) I keep leaving it on standby And then coming back to it And it's VERY hot,. And the battery is almost or completely drained.
I assumed this was some app In the background, so I tried restarting it And charging it - but it was the same problem.
Last night I restarted it, charged it fully, then this morning I made sure I went In And "killed" anything running In the background - so I've got a fully charged phone, not running anything, wifi turned off, etc. I then didn't even look at it until I got to work. When I did get to work, it was hot, And 40-50% of the power was gone... In less than an hour And a half!
I'd much rather fix this than have to get a replacement or my money back, so I'm open to any advice!
P.S.. I've not installed any new apps recently either.
If I remember rightly, all my problems seemed to have started after the firmware update.
My phone also keeps randomly rebooting.
I have now done a hard reset to see if this helps. If not I'll send it in for repair.
teburne, I suggest a hard reset first, then if things don't improve, send it away for repair unfortunately.
First of all thank you for your enquiry. I am sure this is something that can be resolved quickly and easily
It would appear you have tried all you can do for now, I would recommend that we have the phone sent off for repair.
Please let me know how you get on with this.
If you read a few Android forums, the phone going hot and draining battery is usually a sign that some process is in an infinite loop, or a wakelock as they prefer to call it. Email tends to be a common one, especially Exchange Activesync coupled with some kind of Juice Defender which kills connections (you need to setup to be on push mail rather than pull if you use juice defender).
It's almost certainly going to be a piece of software, so sending a handset off for repair is a bit drastic. Backup your stuff and do a factory reset and if it was software apps/config then these will be wiped so it should hopefully stop.
My experience on the Galaxy S 2 was that automatic background sync can be quite a killer.
You could use a tool like this https://market.android.com/details?id=cz.psencik.simple.autosync to turn off autosync on all apps except for
leaving all the *contact sync* to only happen every day.
For me this significantly extends the battery life yet doesn't stop tweets, emails coming through instantly. It won't get you as far as juice defender, but will likely give another 50% or so.,
The repair link comes up with 'An Unexpected Error has occurred. '
I am also seeing terrible battery life with my sensation. It will now only last about 24 hours without a charge - this is with EVERYTHING turned off! wifi, gps, background data, nothing set to sync.
The final straw was last night, went to bed with phone at about 80%, 8 hours later it was dead! As I use my phone as an alarm this is terrible.
Look at the battery graph:
This looks like poor phone signal basicly killed the battery. My sim is looking a bit battered so I'll try getting it replaced, but even so surely this shouldn't be happening?
