How I manage to get 40% battery even after 24 hours

[Guest M Azmin Ishak]

I had an interesting and chilling experience to share.

A day before yesterday, I upgraded to HI1 from HH1. During the flashing, something not right happened when the flashing stucked after PDA part flashing. The flashing just hang at Com Port 18 opened. I am not so sure why...

It really pissed me off but I had no choice but to unplug it. To my surprise, the flashing did not damage my phone but I ended up with the following:

My PDA part now run on the new HI1

My Phone part now run on the old HH1

Now, I am running at 40% battery after 24 hours. So far it is the best battery performance compared to my previous PDA phones e.g. HP Ipaq, Dopod 838pro, TyTN II. Those at best would run from 7 am up to 7 pm only.

How to increase the battery performance for this i900 omnia:

1. Upgraded to HI1 ROM

2. Do not enable auto download in the Enhanced GPS settings.

3. Do not enable HSDPA in Connection tab under Settings.

Hope this will help to all Omnia users....

huh? ;) 1 day and your battery drop to 40% from 100%? should that consider good battery usage? i'm checking mail almost every hour, making about 30 mins - 1 hour car a day, 3-5 sms and once a while check time on the phone (coz i dont wear watch). and the battery level drops about 10-15% per 24 hours, isn't this suppose to be more "normal"?

HSDPA is on, because i'm using EDGE.

XTRA GPS is on but Auto Download is Off.

the only thing i realise draining battery is Push Mail, i off it since i do not subscribe to Push mail service from my telco.

Im using HH3 at the moment.

Xtra GPS = On,

Powersave mode = On

HSDPA = On (as my area is HSDPA enabled!)

Its checking email imap box every 60 minutes and downloading FULL emails.

I would say fairly moderate use, probably be about 20 texts per day out and maybe 40 in,

around 45 mins of phone calls out/in

Probably use a few meg just pissing about on wap/internet when bored.

Normally if the battery had just come off charge that morning, the following morning it will be on about, 60%, typical use the following day will take the battery quite regularly into the third day (admitently it wont last much past 2pm)

[Guest Omnia_1]

HH3 also, moderate usage, 5-6 calls per day, minimal GPS usage with xtra enabled, gprs enabled and so far about 15-20% loss per day. I have disabled quite alot of process and SIP's too. The large start menu is the first thing I disable.

Im using HI1/XXHI2 phone at the moment.

Xtra GPS = On,

Powersave mode = off

HSDPA = On

moderate consistent usage. On HH3 got 40 hours, now moved to above and get nearly three days 72 Hours. Will try Powersave mode on to see what effect this has but very happy with the combo above. Signal Strength could be better, but as mentioned in another thread 'what you see is not necessarily what you get.'

I can make and receive calls / data with no bars quite happily.

what you see is not necessarily what you get.

LOL i strongly agree on this ;)

[Guest Geronymous]

Any expert that can indicate the theoretical difference in power usage between 3G (HSDPA disabled) and 3G+ (HSDPA enabled)? Is the difference so significant?

Regarding the XTRA auto download... if you put it to download once a day, it shouldn't use that much battery. If you are downloading emails on a regular basis (I do every 30 minutes), the data connection is on all the time anyway, so I expect minimal impact from XTRA, right?

What I am interested mostly is the effect of the Powersave function... any experiences?

I know Omnia can last for three days. At least that what I saw in a review from a local computer magazine (CHIPS). Frankly speaking for me, 2 days is better than my normal 7 am to 7 pm :wacko:

this is the first pda that last that long for me. never had this good experience will dopod 838pro and htc tytn II.

by the way I already had a spare battery with an external desktop battery charger bought in ebay. pretty cheap...
