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.

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.

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 :P (with and without bluetooth carkit), i get to use my phone for about 16 to 18 hours without need for a recharge.
How do you enable auto email send and receive?
Cant find the option anywhere

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 cr@p 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, 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.

Had a quick look at your link and yip, looks good going to try it as well.

Mine only lasts 6-8 hours even when not being used and on standby mode, unit also always feels slightly warm to touch. no wifi, bt or any other programs working. tried b-idle program to check for idle time and it does show idle time. Sometimes (maybe 3 times) I have got the unit to cool down on standby and hold its charge but for no apparent reason. does anyone else have this problem? I posted in hermes under battery drain problem if anyone wants to see the details
