Hello everyone,

I have the exact same issue you guys are all experiencing. I am from the UK and am on the Orange network. I am new to the forum but i have purely signed up due to this complete disaster since updating the mango update, let me give you all some background.

Firstly, i have a Windows 7 Phone, Samsung Omnia on the Orange network (UK)...it is a i8700 model.

I updated the phone to the Mango update on wednesday and ever since its been a nightmare!

Firstly, i have noticed that my emails are automatically updating every 15minutes despite them being set to update manually only! and secondly that my battery life is just being drained massively, consistently ....

I first noticed this as my battery only lasted around 4-5hours at home on my day off on thursday after it barely being used after one quick use of 3g in the morning (about 10mins) and afew txts! For the record i did Not leave 3g on! 3g was off apart from 10mins in the morn.

The next day at work after an overnight battery recharge i thought it was my battery that had broke.. Over the course of friday morning i found my battery draining extremley fast again!

BY mid afternoon it was on 44% when i did a restart of the phone it dropped from 44% to 7%!!!

I did a reset on my phone that night of everything, i even tried the fix from the first post in this thread and i drained my battery and startd a fresh charge from mains plug.

... This was fixed until last night when i was fiddling with some settings and trying to get my phone back to normal and then after a turn off/turn on the battery life suddenly it instantly starting decreasing again! so i tried going into

Settings > mobile network > network selection and instead of automatic i set it to Orange, this fixed the problem! or so i thought, we tested it on off with it set to autonatic and battery drain, set to orange = no drain! perfect!!

Anyway, everything was fine until 3pm today and all of a sudden i went into my emails and the problems started all over again! i checked my emails and it had stated that i updated them 2mins ago! how could this be when i hadnt been in there for 2hours?! my emails are always set to update only manually! wierdly the master email account had still not updated for 2 hours, yet the secondary and third account was updating every 15mins, but by default isnt that the mango default setting? yet it was doing this despite me setting my settings to manual only!

My theory is MANGO is unstable! it has not been tested correctly before its release and it is just running some random set of connections/processes that are unaccesable by its user

Obviously something is resetting my settings behind the UI that isnt accesible by the user...as i have not changed any settings or anything like that... I feel this is a software bug/flaw that is present in the Mango update and would welcome anyone else sharing there experiences in this issue and how to best forward this problem to a resolve.

Thankyou.

PS -- can i go back to the pre-mango update by zune? as i think mango deserves a good years work by microsoft and then re-releasing
[Windows Phone 7 General] Magpir:
I had the same problems as well.... I believe the problem is with the htc firmware.

have u received the post mango update?

i have installed the HTC firmware update (27 october) and it feels improved battery life, performance ect...
[Windows Phone 7 General] melvintwj:
Here's my battery after waking up this morning. Was using my HD7 to play games last night.
[Windows Phone 7 General] Magpir:
There were some bugs before this update

They were

1) battery saver turned on seems to drain battery more than not turned on or is not working

2) when battery saver is turned off, the phone uses cellular to check for updates immediately even though wifi is On ( u can see the icon change from 3g to h immediately)

3) incorrect battery indicator when left for rest for long periods of time, whe u start using the phone, it drains rapidly to reflect the current level , or fluctuating indicator levels when phone is restarted.

4) power consumption during rest is more before this update(20% vs 8%)
[Windows Phone 7 General] Magpir:
I am yet to test this update ....

As for the bugs listed above.others can confirm?
[Windows Phone 7 General] tfn:
Battery Drain Culprits:

1 ) Htc Hub - If you allow it to auto check locations it will run in the Background.

you can check what apps run in the background in settings>background tasks.

2) Rogue apps from market - I installed a recipe app and it drained my battery within less then 5 hours, that is why when you reset your Device the apps are gone and so is the battery drain.

Best to install only apps you really require delete the ones you dont need or use.

3) Multitasking - Mango is designed to multitask (more or less like android) so you will get a much worse battery life than nodo.

4) The more you use your phone the more battery is wasted as with most big screen phones these days . screen is the biggest battery hogger.

5) Locations -- All apps requiring locations like Htc Hub / Maps / people / camera etc. it mught help if you change the settings to not use your locations if you don't need them

6) find my phone - This is entirely upto you :D

I get around 2 days if I just leave the phone idle but around 10 hours of normal

usage.

I guess I myself will try how the above affects me :D
[Windows Phone 7 General] blurayfan:
Guys, i just need to start by saying i am Not using an HTC... I have a samsung omnia i8700 phone. its on the orange network.

I have done another reset and managed to get battery life okay... I have only installed facebook app... I have removed all orange apps (orange wednesday app, orange daily app, your orange account app and orange maps app)... I also have not bothered with the ebay app this time around...

So ill see how it goes for now, you guys mentioned a post-mango update? .... Is this sent through zune or your network provider?

Many thanks!
[Windows Phone 7 General] Magpir:
update thru zune
[Windows Phone 7 General] Magpir:
cant seem to turn off find my phone

uninstalled HTC Hub

for google reader i use nect gen reader which has option to update every 6 hours
[Windows Phone 7 General] blurayfan:
Thanks - ill check zune later tonight :)

As for mango, bugs im finding are;

Battery drain issue,

Emails bypassing user settings and updating every 15mins regardless,

Internet explorer always goin to base of page when multitasking,

Internet explorer having problems with logging in on webpages (forums, accounts etc) almost like cookies arent working correctly despite being on,

Samsung tones and sounds have dissapeared after reset,

Local scout app and help+how to app appeared after system reset

Thanks.

yes, same here... Find my phone is connected on mine and cannot be turned off?!... How is this Possible?...

I have two options under 'find my phone' - connect to features more quickly and save my location more regular, both are Unticked!

Could this well be that the phone is just running hidden settings which is draining battery life?... I mean in a sense of course all these extra features will use more battery but its like they are on despite being set to off!

Id also like to know if my phone can be debranded from the orange setup i have?!
[Windows Phone 7 General] blurayfan:
update! -- just had my battery screw up again!... Surfed the net for like 10mins or so using 3g... Sent afew txts ... Left phone on side for like 15mins, checked battery life and it said 50% remaining (3hours remain)... I thought this was abit low for 50% so turned phone off and back on and low and behold battery 14% under an hour remaining! .... On a good note emails are not updating every 15mins as before!.... i have just tested a new idea!....

I turned flight mode on andmy battery stated 15% remaining (3hours remain!) ... Does this officially cryout that the problem is indeed a network/phone issue.... My guess is the phone is overprocessing certain network needs and its just killing the battery.. So hey! Answer is disengage the network! I mean why not its a mobile phone -- why should it do wat its designed to do!.... Im so annoyed right now...

Im going back to pre-mango tonight! .... Mango has been the worse pile of trashever!! :(
[Windows Phone 7 General] Magpir:
Well only nodo can turn off find my phone.

In mango , even if u untick the 2 options, it still says connected

I believe its similar now to apple killswitch in iPhone that allows Apple to remotely delete malicious or inappropriate applications stored on the device that may spread viruses over networks.
[Windows Phone 7 General] blurayfan:
Thanks for that. Can anyone confirm the problem over the battery drain?...

My battery had that crazy turn earlier but now it appears to be stable again?! I am utterly baffled at the cause of this problem!
[Windows Phone 7 General] Magpir:
So what did u do now that yr battery life is normal?
[Windows Phone 7 General] blurayfan:
To be honest nothing, the battery went crazy.. I put it in flight mode on/off... Deleted internet history, turned off location (despite it being on all morning/early afternoon!.. And it made no difference in battery life for that period)... And then i put phone on charge and did a turn on/off, it just settled down somewhat.

Its just completely unpredictable! im going to rollback firmware tomorrow after alittle longer seeing how this "debacle" goes.
[Windows Phone 7 General] ScottSUmmers:
Could also be a battery gone bad. I wouldn't rule out that possibility.
[Windows Phone 7 General] blurayfan:
True, however the issues i have experienced before (as listed in my previous posts) i would likely suggest this firmware is just unstable.

I think ill retry installing the ebay app and orange apps and see just how much of a difference they make to battery/settings overall... Worth a try before i rollback :)
[Windows Phone 7 General] majkeljj:
Magpir please tell me what firmware/software version is after 27 october update?

My zune don't see any updates, but my phone was in service, maybe I have this update applyied.

My battery is better with un-typical settings, all to manual, and with data connection on and 3G on is better then with 3G off, i have manually selected carrier. One more interesting thing is after I got back Mozart from service, oryginal HTC battery works longer that 1800mAh Mugen battery :P before service Mugen was better :P crazy phone :P
[Windows Phone 7 General] Magpir:
bootloader = 5.0.2250.1(130781)

Radio = 5.69.09.05a_22.50.50.21U

Firmware = 2250.21.50001.XXX
[Windows Phone 7 General] majkeljj:
I have something totally diferent:

bootloader = 5.1.2250.4(131830)

Radio = 5.71.09.02a_22.51.50.21U

Firmware = 2250.21.50104.XXX

it is possible it is newer then yours?
[Windows Phone 7 General] Magpir:
mine is a Asia HD7

its possible its newer if HTC goes by incremental version numbers

But if it goes by region numbers, then its hard to say
[Windows Phone 7 General] majkeljj:
My is HTC Mozart Europe->Poland
[Windows Phone 7 General] Magpir:
hello fren, u have a mozart and i have a HD7

so the version numbers may be different
[Windows Phone 7 General] smahmood143:
what radio are you using?
[Windows Phone 7 General] Magpir:
5.51...

but now accidentally i updated to the latest firmware which cant be downgraded

even radio cannot be downgraded.
[Windows Phone 7 General] Smoothound:
This is really intermittant.

On my previous tests, to get rid of the chance of multitasking being the issue, I have powered the phone on and off when I take it off charge.

This morning I didn't, and I used the Facebook app for a while over WiFi. I've left WiFi on as usual, didn't bother to close Facebook.

It's now reporting

Remaining Battery Life 80%

Estimated time remaining 11 hours

Time since last change 6 hours

17 hours estimated in total. I could live with that every day! Thing is, I know tomorrow I'll get half that again :confused:
[Windows Phone 7 General] N8ter:
Battery saver values are inaccurate. I've had it tell me 1 hour remaining with 90% charge remaining. It basically changes by the minute depending on what you do with your phone and will always give incredible values if you check it after the phone has been relatively idle for a minute or so.

Its only useful for seeingbwha the current battery level is and how long its been off the charger IMO.

My HD7 still loses half a charge in an hour or so just texting and doing some light web surfing b
[Windows Phone 7 General] Smoothound:
I guess we'll have to wait and see. To give the feature credit : thus far, for me at least, it's been very accurate. Well...I say that, for sure it turns itself off at zero % (I guess if it's inaccurate there could be charge left)

Ho hum! :rolleyes:
[Windows Phone 7 General] Magpir:
There is nothing wrong with the fluctuating values

The only time u shoukd worry about is if battery saver is working.

There seems to be a bug in htc Asia hd7 devices before the 5.0 boot loader update where the battery saver drains battery instead of saving.
[Windows Phone 7 General] Smoothound:
So last time :

I actually got more like 20 hours in the end. More like what I used to get give or take.

This morning, once again a full charge overnight :

Remaining Battery Life 29%

Estimated time remaining 1 hours

Time since last change 3 hours

Four hours? :rolleyes:

I have no background tasks, all I've done since the previous charge (i.e. yesterday) is make a phone call and check some emails via Outlook/Exchange.

This morning all I've done is check Facebook app.

This is so unpredictable.
[Windows Phone 7 General] Smoothound:
I turned off the Battery Saver on Friday, had a good day's useage out of it too :)

Then, yesterday was rubbish (I didn't use the phone at all, just took it off charge)

Remaining Battery Life 5%

Estimated time remaining 1 hours

Time since last change 5 hours

Today is looking good, I've used it to check Facebook app, Exchange email and play some MP3s in the car.

Remaining Battery Life 96%

Estimated time remaining 14 hours

Time since last change 4 hours

I can't build up a pattern to suggest on particular app, or any particular behaviour to make the battery drain. It's really seeming to be totally random to me. :confused:
[Windows Phone 7 General] N8ter:
We are all aware that smartphones get decent STANDBY tunes, which is basically all you're seeing with that little use on the device.

It's the in use time that's terrible.
[Windows Phone 7 General] Smoothound:
No mate, it's standby too! I can charge the phone to 100%, pull the battery out, reboot - still says 100%.

Then do nothing.

4 hours later it's flat....sometimes.

Other times, I charge it up, go on facebook, play some MP3s, and get 20 hours.

RANDOM!:confused:
[Windows Phone 7 General] Magpir:
It has something to do with charging.

I discussed about these in many posts, the charging used by htc seems strange.
[Windows Phone 7 General] StriderNo9:
Just to put my two cents in. I have a Focus S and the battery lasts me about 11 hours on week days when I am using it moderately. No more than I did my Focus which lasted like 30 hours most times. on weekends when the phone is used much lighter I can get like 24 hours or more out of it.

I swapped my battery at AT&T, I have went through multiple charge cycles, I have turned off background apps, and even reset the OS like 3 times, I am not going to try the SIM card trick. Hopefully that works.
[Windows Phone 7 General] N8ter:
See thats the issue. If I'm going to do all that, I mind as well just roll back to NoDo. You're crippling the phone for longevity, when it should be MS fixing the issue. Its not an OEM issue cause too many people have reported significant drops in longevity after the mango update, on a wide assortment of handsets.
[Windows Phone 7 General] JC_Agga:
There is a literally an app called Toggle or Toggles in the marketplace, it's an app for wifi, bluetooth, data shortcut to your homescreen so you can just click the pinned wifi for ex and turn off instantly. It even tells you if data or wifi is turned on when you pin it!

I'm not sure if my 1400mAH battery is doing a fantastic job, or i only get 2g service on my device, but i get out of my place at around 8:45 in the morning, come back home at around 7, or sometimes 9, and i use zune alot, 10 websites wth wifi on, play some games, text, and everything turned on from background apps, location services, find my phone feature on, and pretty much everytying is on except bluetooth and i get about 15% battery remained at the end of my day. I have WP7.5 and Venue Pro. So i'm not sure if people with having battery issue are lying or i am just lucky?
[Windows Phone 7 General] StriderNo9:
Seems like the SIM trick didnt work for me.
[Windows Phone 7 General] timmes:
Turn of 3G

Turn of location

Turn of Bluetooth

and set mail sync to manual.

I can work 2 days with my phone now.

LG E900 optimus 7
[Windows Phone 7 General] majkeljj:
agreed.

on my mozart now with light use and this settings I have 56hours without charging and still 45% left. (mugen battery 1800mAh) I ON data connection only when i have to use it. data connection drain battery a lot.

I hope new comming update will improve this more.
[Windows Phone 7 General] Smoothound:
I've not really changed anything. All radios are on except bluetooth (same as usual)

Battery saver is OFF

What I have done differently, is charge the phone for 2 days solid, even though it said 100% charged.

Remaining battery life 40%

Estimated time remaining 6 hours

Time since last charge 1 day 17 hours :eek:
[Windows Phone 7 General] nok_fusion:
hmm weird,can u confirm that u remaining battery i better than before?
[Windows Phone 7 General] Magpir:
yes this is what is also recommened with mugen batteries.

but we need mOre details, whats yr usage pattern like or is it on standby all the time with no usage at all?
[Windows Phone 7 General] Smoothound:
Useage : typically on standby. I have one Exchange mailbox, one Hotmail, and three gmail accounts set up. Facebook chat is off.

In any day, I will use the Facebook app or the built in functionality to update/check Facebook. I will do a couple of Bing searches a day. Maybe send a text or make a call, never more than one call a day, this is very much a PDA for me.

I'm off work at the moment, so my activity is less, probably the most significant thing I hadn't though of - I removed the Exchange account. (that said, the other 4 mail accounts are still active)

I guess it must be the Exchange account? But not everyone has one of those right? :confused:

I've still not charged it. It's saying

Remaining : 31%

Estimated Remaining : 4 hours

Time since last charge : 2 days 15 hours
[Windows Phone 7 General] Magpir:
well, I see to have such figures like 1day 17 hours before the 5.0 update. But it never lasts that long .

now I have like 17 hours after the latest firmware update . says the same thing al the time. Last night I charged very long like more than 12 hours. The battery drain vs usage seems better now.

although it says 17 hours, I have 72% remaining after 2 hours of heavy usage .

So it seems logical to charge it for more than 12 hours.
[Windows Phone 7 General] majkeljj:
this battery usage indicators are useless it don't deliver real data.

I have now: 68% battery left. 23hours from last charging and remaining time 1 day 20 hours:P and im' sure that today evening I will have 20% left and >20hours remaining - not first time, but phone will die in next 2-3hours. so this are only estimates datas based on previous times from charge to next charge.
[Windows Phone 7 General] Smoothound:
I suppose...but I never had to before Mango. I used to get two days out of the phone one one charge and be able to charge it over night.

If it is the Exchange sync which is draining the battery, then it's something they've changed in how that component works as I have always used that feature and it never caused excessive drain before :(

I'll keep with it anyway, and see if the drain issue comes back when I re-sync with Exchange. Currently 3 days 13 hours since charging. 5% left,so I think I will have to charge soon!
[Windows Phone 7 General] Magpir:
smoothhound, what phone ar eu usng

i am on HD7
[Windows Phone 7 General] aptcore:
If you are only using 2G data that may explain your " longer"battery life, as 3G uses more power. Also Wifi uses less power than data connection. I found out that my battery drains 2% every 15 minutes in IDLE state with HSDPA on, WiFi , location and BT off with all apps closed and even when battery saver is on.

Sent from my LG-E900 using Board Express
[Windows Phone 7 General] Magpir:
i think the culprit here is the Find my phone

In mango there is no way to turn it off
[Windows Phone 7 General] ScottSUmmers:
I thought you just uncheck, "Save my location":confused:

Anyways, I guess the HD7 sucks, cuz my 7 Pro has done nothing but gained time according to the meter. Obviously depending on the task I do, the battery will drain faster and the estimates will adjust accordingly, but overall--yeah, gained time.
[Windows Phone 7 General] Smoothound:
To recap - I removed my Exchange sync over Christmas and found that I immediately got better battery life.

I just wanted to post up and let you know that since returning to work and adding my Exchange account back, I've had no problems.

I can easily get 24 hours out of my phone again.

So in my case at least, it was some weirdness with the Exchange sync. It seems the Mango update does *something* to Exchange sync which makes it drain battery - removing the account and adding it back in seems to fix it. In my case at least.

Hope that helps someone else!

EDIT : I've turned all the other stuff back on too, including Facebook/MSN chat :D

hmm.. Using a HTC HD7 I thought my battery was quite bad.

At 100%, after a night of approx 8hours charging it says:

Estimated time remaining : 1 day 4 hours (occasionally a bit more).

Reason I thought / think its quite low is cause a mate of mine uses a Samsung Omnia 7 and he gets nearly 2 days after a full reload.

Although the battery in there is 1500mAh while mine (HD7) is "only" 1230mAh

Now after coming back home from uni I saw this

Remaining Battery Life: 59%

Estimated time remaining : 15 hours

Time since last charge : 11 hours

---

I did as you said the "trick" with the Sim card, which seems like a weird trick indeed :)

But this was the outcome:

Remaining Battery Life: 62%

Estimated time remaining : 17 hours

Time since last charge : 11 hours

Now I have no clue if it was just by rebooting the phone or the actual Sim card removal or if its temporary or an actual fix, but for some reason it worked and therefore I can only press the "Thanks" button for ya.

Hope its "fixed" cause I dont feel like doing this thing (every couple of) day(s), hehe.

[Edit:] For people using a HTC HD7 I can only say that the biggest culprit in this whole scenario is the weak battery (1230mAh) to power a bigass 4.3" screen, while most phones have a 1500mAh+ battery, aka better battery life. And this for in most cases a smaller screen
[Windows Phone 7 General] Foxnov1990:
Small update, I managed to flash a ROM so that I could revert to 7720 (to interop unlock) and back to 8107 after a Hard Reset and this is what it reads now.

Remaining Battery Life: 99%

Estimated time remaining : 1 day 17 hours

Time since last charge : less than an hour

Eventhough the battery sucks bigtime for the HD7 I recommend to hard reset your phone and afterwards put your apps back on there (either installing everything again or backing it up first with "Windows Phone Device Manager")

[edit] not sure if its just the 8107 but the reset "gave" me approx 14h extra, enjoy!
