Battery Life with Direct Push

Just wondering if anyone else is having this issue. I set up my Wizard for Direct Push with the Exchange SP2 server at work. No prob though I did get duplicates. Anyway, yesterday, it worked great, received e-mails even before the computer at my desk, but by the end of an 8 hour work day, my battery life was down to 43%. Is this supposed to happen?
Today I tried disabling the push and after the same 8 hours I have 97% battery. Anyone know what to do about this?
Thanks for the help.

Not fully understanding how the push email system works (I don't have the need for it, nor the pocket to fund it's use on Australian tariff plans), but doesn't it just stay connected to the server through GPRS, sending a 'heartbeat' every couple of minutes to keep the connection alive?
I think it is something like that. If that is the case obviously it is going to effect your battery life as you are using your phone as normal, plus fulltime gprs use and then the backlight/processor when reading/replying to the emails.

Average Battery Life ? ? ?

What is the average battery life most people are getting from their devices? The reason for asking I beleive that my battery life has reduced drastically, I'm averaging 36hours. I do not use it as a phone, the Wifi & bluetooth is switch off, the unit is used for push email only and I receive about 20 emails per day, very little WEB browsing.
I'm sure my battery life was a lot better when I took delivery of the unit.

Mmmmm.. well I'd consider 36 hours fantastic but then it sounds as if I use mine a lot more for wifi, surfing, phone etc. than you. Perhaps an hour to hour and a half per day and charge once per day but will usually have 40/50% charge left I did see a post from someone saying with reasonably heavy use they could only get 8hrs.
Mike

i use mine mostly for data.. in a 3G area i average about an 9.2% loss per hour.. in a edge area i am averaging about 1.7% loss per hour... these are all estimates since the battery meter only goes by 10's

I am fairly certain that the 3G is eating power. I get a full days work out of it with a lot of phone calls, push email, BT always on, and occasional WiFi usage. I am almost always in 3G, I very rarely lose it and only when at a clients far away.
Later, Lew
BTW, A full days work for me is 9am to 3am.

3G is the problem. Consider switching to 3G via MortScript as described in another thread. Personally, I use the GPRS only setting for normal use. PushMail would consume a lot less energy with GPRS and the speed isn't such an issue for mails in my opinion. Whenever I'm willing to browse the net a bit more, I switch to 3G before doing so (takes ca. 15s via the script) and when done, I go back to the less battery eating and more reliable (for taking phone calls etc.) GSM only mode.
You will definately at least double the runtime of your Hermes. I can do 5 days (phone on at night, little use) by doing so.

Well I can confirm that 3G is the cause, as suggested I've switched to GSM and battery life is a lot better.

3rd charge i managed to get nearly 2 days, had a 4 hr gprs web session last night on minimum brightness and still had 30% battery this morning.
if the battery goes to 0% what happens? data loss or just turns off?

Other than any document/application open at time of shut down you should be ok, not like my old Clie that looses everything that's not screwed down on the storage card. In fact quite often I deliberately remove the battery for a while if I reckon it may help with a lock up (normally due to some rubbish downloaded freebie!!). All saved programmes to Device memory and card remain in tact.
Mike

Using my TYTN for email (check every 30 minutes), newsgroups (check every 30 minutes) and reading both every 2 hours.
Also using the phone for lots of browsing.
And i am also using my phone for making some phonecalls over the day (with and without bluetooth carkit), i get to use my phone for about 16 to 18 hours without need for a recharge.

[OT]
How do you enable auto email send and receive?
Cant find the option anywhere
[/OT]

if you add an email account to your tytn you get the option advanced at the end of the settings. if you click it you will get the option to send/receive at a standard timeperiod.

I use UMTS for email and web browsing continuosly for 2 hours and I'm down to 10% after a full night charge. It's pathetic.

Your device is broke, or your battery is defective. Seriously, if you have a warranty, act on it.

i dont know about that.. everyone seems to be getting around the same battery life... i would bet that if i used mine on umts continously for 2 hours i would be close to the same drain, UMTS sucks alot of battery

that's true and umts sucks a lot of power. i am using mine on umts in tokyo and i can only get 10 to 12 hours. i use it mostly for push email (about 80 emails), an hour of browsing and some phone calls a day. i've ended up purchasing mugen's 3000mah one to get through the day without recharging.

I highly doubt it as I have two 8525 and both of them will be at 10% with 2 hours of continuous use.

Well I'm on my 2nd battery.First one was replaced under warranty as I was getting about 8hrs with very little usage.
I'm on my third charge with the new battery. The first & second charges have given me about 15hrs.
Agent said I should be getting 4hrs talk time and if the second battery is also [email protected] then they will replace the phone. So I'm monitoring until next week.

This may not apply to you (as you probably know it already!), but Windows Mobile does not shut down programmes when you click the x in top right corner. To ensure you are not unknowingly running lots of applications in the background you need to use a programme that really shuts applications down properly - e.g. Magicbutton or HTC X Button. This can save considerably on both battery power and performance.
Mike

Mike, I'm using Magicbutton and make sure all apps are closed all the time. I've read a lot about the UTMS connection on all the time draining battery. I've just downloaded this app: http://www.gb-soft.cz/XDAII/product_gprs_tweak_wm5pe_en.htm
See if this works and extends battery.

Battery Life using PushMail

Hello all,
I'm using PushMail with MS Exchange and I am very happy about figuered out this feature. But now I have a new problem. If I have charged my battery up to 100% it only need half of a day to be empty without using my hermes (only UMTS for Push Mail)
Has anybody the same problem or a sollution ?
Thanks
sunmaker

Ok, try this. Open your maillbox in Outlook, then send yourself an email from another email account. Does the mail item hit your hermes and your inbox at (about) the same time?
note: if you have cache mode set in outlook then it should hit your hermes before you see it in your inbox.
If you can't access your mailbox with Outlook, then use OWA and hit refresh often to see when the mail item hits.
I suspect that you're going to find out that mail to your Hermes is delayed for up to 7 minutes from the time you see it in your outlook/owa viewed inbox. If you are seeing mail hit at about the same time, try this test periodically for an entire day to see if there's any time that this isn't the case. Let me know what you find out!

It's UMTS that is so power-hungry.
download Daniel Herrero's Bandswitch and force GPRS-only, to see the immediate result. Let us know; in my case it improved battery life from 20h to ~80h.

This doesn't necessarily account for a one half day drain. I'm on UMTS direct push and I go two days between charges. There's something else that I'm thinking about here. If sunmaker is seeing the delay I'm looking for then I'll reveal the reason.
Btw: on mine, email always hits my TyTN before I see it in Outlook.

You should be able to survive around 2 days with UMTS + DP .. and approx 3 days with just UMTS ...
You need to check for any processes/services that might have excessive CPU utilization ...

I have around the same usage in between charges. I get around 2 days with PM+UMTS but if I use my device extensively during the day i charge the same night.
half a day to empy sounds like there is a process chewing up your amps, or the battery is faulty.

It entirely depends on usage.
I get two days (similar to others above) using push and UMTS.
However, if ihave wireless enabled and bluetooth too, and using a bluetooth headset and make a couple of hours of calls in the morning, i'd be hard pressed to last the day out on the same charge.

I'm running Pushmail and UMTS also Bluetooth is enabled all day.
i spend about 35 minutes a day in calls and do send about 5 SMS mess. a day.
My battery last for about 20 hours.

Like i said, entirely depends on usage.
i recieve close to 30-40 work orientated emails a day ,of which at least 20 get replies instantly. add in 2hrs easily of actuall call talk time and its easy to see where my battery life goes.
a lot of people whinge about battery life, but if you expect alll the bells etc that a good WM5 device has theres going to be issues with long battery lifes.
My blackberry 8707g using UMTS and recieving maybe 10 emails a day barely last a day and a half from full charge. Thats without much else, and probably 10 mins of call time. SO i consider the Dopod 838Pro (or Hermes! ) to have more than adequate battery life for what i use it for. Besides a great, powered car holder and hard wired GOS device in the car has just about made this Hermes the best of any unit i've used, WM5, WM2003, Blackberry and palm inclusive.

thank you for so much response.
I have about 30 Mails per day some SMS and 60min phonecalls. I'm using the 1.20 radio so far. Could it be the radio ?
The radio versions i used before I have a lot of trouble with. Because my Hermes always loged out.
I have no other progs in the memory only the necessary (CommMgr, Active synk, Email).
I've ordered some new batteries (1350mAh ans 2.400(!) ) So I will look and see if it is the battery.

HTC TyTN Battery Life with ActiveSync Really bad

Hi
I have read a lot of threads about short battery life, but so far none of those applied to me. I have recently purchased this great device, and normally it gives me 2 days of usage time with a fair amount of fiddling etc, and no activesync. Now the main purpose for this purchase was the Activesync feature, as I have an exchange server pushing me my mail. I have the following settings:
Exchange 2003 SP2 without SSL certs/encriptions
Active sync set to download mails upto 0.5KB and from all times, not only the last 3-5 days, etc.
Active sync is also set for immediate retrieval, which leaves the phone with a permanent GPRS connection. There are PEAK times set, from Monday through Friday between 8AM to 6PM. Off peak times it gets it at every 2nd hour.
My battery lasts 12-14 hours like this, and I dont touch the phone much, plus dont have more than 20 minutes talk time per day. Yesterday I arrived home at 10PM with a dead battery already. This is really bad that I cannot even make it through a single day.
An addition to this the phone gets really warm, but only at the very end of its battery-life, lets say from 30% to 0 it goes in less then an hour or 2, and warms up pretty badly.
I also have the BandSwitch utility keeping my phone on GPRS only, and killing idle connections that are non-used for over 2 minutes. This I guess only takes affect during off-peak hours, but even in those hours, when I check my phone I can see a GPRS connection on for like 20-30 minutes. So I guess Bandswitch doesnt always do a good job.
Any hints? This is really annoying,
Thanks a lot,
Ben

How long does your battery last with internet on 24/7

hey guys. i just wanted to know on average, how long does your battery last with either 3g or edge on 24/7. from what i been experience, after a full charge with edge on, i make one phone call and my battery drops to 90%. after that, from morning till night time, it drops to around 30% at around 6pm with minor activities. so i just want to know how long does your battery last for all you internet users.

My battery lasts about 72hours if only bluetooth is activated and EDGE/3G is used and I use it "normally"(read a few emails and a few phonecalls).

I don't believe EDGE is ever always on...
I use WiFi almost the entire day while I'm in my apartment doing work and constantly getting important emails. My battery could probably go 48 hours but I charge it every night.

ur right its not always on. however, i have few programs that is set it to connect every 20 mintues, so lets say i do get disconnected, it will reconnect and refresh.

Yea I understand. I'd say if your battery isn't lasting all day with minor usage, something's up.

something between 24 and 48 hours, depending on how many phone calls i make and if WiFi is on or not.
usually i talk a bit on the phone, 24/7 Internet through Edge/3G and Push Email enabled i get 40 hours.

my battery life
my battery lasts for 14 hours i hear mp3s on bluetooth headset ,i use 3g couple of times check my inbox or so... wireless s used for 30 mins and 2 hours phone calls and some snapshots using the cam

When browsing ALOT through the day less than 24 hours.
Using often Opera Mini 4.2.
With Opera Mobile 9.5 even less (much more data).
I never keep my internet connection open constantly, always turn off after using.

I've been using CSD to browse the net for the past 4 hours. the screen barely ever turned off during this time. I'm down to the last bar of battery. does that sound reasonable?

seems reasonable enough. when im at work, screen barely goes off since im always using palringo to chat with my buddies hehe
but yea, after a few hours of usage straight, im usually down to about 40%

The phone only draws power when sending or receiving, more so when sending. Just having the 3G/3.5G connected on idle does not use a lot of power.

Doesn't it eat up the battery if 3G is constantly on, since it is trying to receive a signal to keep alive the connection? Similar to the regular phone connection?

My data channel had been on for 43 hours when I checked this morning. That is GPRS though, not HSDPA/3G. The phone was still showing 20% after almost 2 days.
Battery use with HSDPA though is much shorter, like 12 hours or so.

how do you check how logn our connected? mine doesnt show. i remember back then when i had my tytn 2, it shows the time.

Tap the signal strength icon and it should tell you how long your data channel has been connected. In my case, right now it says:
mobile web (GPRS, 3G) 06:05:10

yea i know thats what i did when i had my tilt. however, on my x1, it just says connected, no time, and no disconnect button.

Question
I have an iphone, and I only use it for email, because I can leave wifi enabled, and it will connect and check every so often, the wifi goes off when its "sleeping" but will switch itself on to check for email.
My question is, with my xperia, if I leave my wifi enabled and put it to sleep, will it still disconnect/connect if/when it needs to and still give a decent battery life?
So far I keep it off and don't even use it for email, but if i can get similar behaviour and battery life to my iphone (giving me almost a week with wifi left on, not being used for anything else) then i can ditch the iphone and just use my xperia.
My only other option was to take out a data plan add-on, i like having my emails checked regularly for me and being notified, but when i tried it on my second day of owning my xperia, it killed hte battery in under 3-4 hours.
Any suggestions, comments, etc?
Thanks.

I am connected to internet 24/7 with HSDPA
Loading web pages here and there around the day, syncing email evey 30 mins, BT 24/7 with MBW-100 watch and my car, WiFi occasional to move files around my work network and home, GPS 1 or 2 times a day, and heavy, heavy phone usage with some videocalls
I even share the SEX1's internet to my desktop computer because it's faster than ADSL
At the end of the day I still have 30-10%
I would say 36 hours of battery life
When I used the Diamond I had to recharge at lunch, TyTn lasted until 3-5 pm
BETTER phone I've ever had, by far
PS: battery drains very fast when sharing HSDPA internet to the desktop PC with WMWiFiRouter, so I prefer USB sharing when at office

always on doesn't mean anything if there's no active data transfer. It's the data transfer that's consuming power, not the fact that your 3G or GSM network is turned on.
For e.g. my phone is connected to internet 24/7 due to my pushmail setup, I do get mails pushed to me, but when it comes to night, since it's off-peak period it's pushed to me on hourly basis. Battery consumption will be around 10-20% over night, but could be less than 10% if I turn off pushmail.
If I were to continuously stream video off from my ISP provider's online TV channel, I would get about 5-6 hours of playback time (I think, since it was awhile since I last do that, can't last full day for sure)
