POOR P800 Battery Life

That is strange... With moderate PDA use I get about two full days on one charge. Remember to close all the apps when you don't use them. If you have a lot of stuff running in the background, the battery will get drained in no time. Use File Manager or Handy Day to close the running apps.

If this doesn't help you might have a defect battery.

I've owned mine for 2,5 months now, and I've noticed that the biggest battery drainers are Bluetooth, GPRS and of course the screen, so it's wise to turn these things(in addition to any app/program that might be running in the background) off when not in use.

I feel the P800 gives great battery life considering it's a PDA/phone hybrid. There's no PDA on the market that can stay on as long as the P800.

I get 2-3 days now with my P800. If I disable the backlight (kinda useless at night) I can get 5-6 days. The backlight drains a LOT...almost as much as making a call.

Turn off your screen saver so the power saver kicks in sooner.

The more you use the phone, even waking it up from powersave mode, the more battery it drains. Leaving the screen on (no power save) eats up less power than having power save kick in after 2 min, only so you can wake it up again after 3 mins.

initializing the components from standby eats up more power than leaving it on. The same goes for making calls. Ten 1-minute calls eats up way more power than one 10-minute call.

My first couldnt last a day. It was on less than 50% by 1 p.m.
I got the replacement and now I can make two days out of it.
I'm not however satisfied with RF at all.

Is the thing to close the apps from qfileman.sis?

Have that but cant see where to close down processes.

My battery also lasts only about a day... if only it charged from usb 😞

You have to WEAR the battery in, let is DISCHARGE COMPLEATLY
then charge it back up to get full capacity out of it.

do a search here to read more...

I heard that could actually do damage to these newer batteries?

Can anyone confirm?

Im quite sure even the manual says to do this for full capacity with the battery on first use as with most things of this caliber with a battery...
anyone?

Andy_P,

By the way, how did you get unlimted GPRS? Costs?

As for charging from USB... Dixons are selling a USB charger which is compatible with Nokia and Ericsson Phones (it's compatible with T68 which has same connector) for a mere �15...

You DO NOT need to close down applications manually. The memory manager will close down unused applications for you when your device is low on memory, and applications that are in the background does not drain the battery at all (except if they keep the GPRS connection open, in which case you can close the connection from the GPRS icon in the status bar at the bottom of the screen).

Ofcourse some apps will drain battery time when run in background... the programs won't freeze when you multitask... Try run EScummVM or DOOM or anything in the background, u'll see the battery only last 3 hours or so... They should be a task man that shows how much CPU the programs are using, so you know which program to close down to avoid battery loss...

IMHO the battery life of the P800 is very good. This is both a fone and PDA, and believe me i have used other similar devices which conked on me after only 4 or 5 hrs. My brother and officemate also use P800 and they also find battery life to be very good. Ordinarily it takes me 2 days before i need to recharge my batteries. Of all the applications i think its Opera that takes alot of juice. I think whatever battery problems people are having has to do with defective batteries. Maybe you can have it replaced

Application developers need to be power-aware and not let for example game graphic animation threads continue to run when the application is backgrounded. Applications that only wait for user interface input (event driven) use virtually no CPU while backgrounded.

hi..if u have use communicam and goboy without closing it using taskmanager...it will drain ur battery within half day...i experience this lots time and do test on them.

check on it

Thanks guys.... I drained the battery TOTALLY... then charged it up fully... now after 14hours (8am to 10pm) it is still at 88%, unlike previous it was 30% by now. Seems to be better... will observe further and report. Am gonna drain it this time again till flat and then recharge one more cycle just to make sure!

Kool, make practice of this 4 best possible life 😊

Remember, that a big power drainer is, when you use the Magic word function, because the P800 is listening, what you say all the time. 😉

So what about the sounds? Do they drain much battery power when switched on?

Roughly how much more standby time would i get if I left the phone on silent? or does the vibration use more battery than the speaker? :-?

Hey gadgetfreak, I dont think its advisable that you drain your battery the all the time because we are using lithium batteryies already. Its not good for these types of batteries to be drained because it lowers there lifespan. Did you initialy charge your batter @ 12-16 hrs before using it for the first time? This is very important. If you didnt do this and just charge it for a couple of hours and used it right away then your battery will not have fully equiped its power charging capabilities. The reason for this is before it was sold to you it has been on standby in the box for quite along time and the battery cell were sorta "sleeping" and you need the 12-16hrs charge to fully wake all the cells up.

These comments are based on experience and comments by other people on other gadgets like the ClieNr70v or other noki or ericsson phones.

i got the battery in SingtelShop $75 😃

Its been 40 hours since last charge... now at 70%... normal use. Looks like it is still going strong. Will take advice and charge before it goes completely flat!

@Muzikfreakah:

I'm afraid I admit I didnt charge mine fully... I used it until it was at about 20% left and then charged it for about 8 hours.

Battery life is now about 20 hours or so (at a guess) as it never seems like it will have enough to make it through the next day so it gets charged every night.

Would it be worth running it flat now and giving it a mega charge?
